Wasteland: My items are infinitely upgraded

The sudden tremor and the booming explosions reverberated throughout the entire Vault ruins.

Judging by the direction of the sound, the explosions originated from below.

And in the lower levels of the ruins, besides the Savior Army's search of the military factory, there was no other human activity.

To use explosives with such power, the trouble encountered would definitely not be as simple as ordinary mutated creatures, but definitely something very棘手.

The resulting mutated creature riot, accompanied by a sudden increase in mental pollution, became a disaster sweeping through the lower levels of the ruins.

"Run!"

They might even leave the group and walk towards the monster tide.

Lin Feng in the front row also immediately took action, raising the large-caliber AK in his hand and switching to the level seventeen rapid-fire cannon mode.

The explosive rounds fired by the rapid-fire cannon could automatically replenish, while the number of holy water hollow-point bullets was limited.

However, when facing the constantly surging tide of mutated creatures like a flood, the single-target attack hollow-point bullets were obviously not as effective as the rapid-fire cannon with its explosive area damage.

Especially the latter's firepower, one explosive round could repel several mutated creatures.

Lin Feng turned his head and activated the Rapid Pursuit attribute, gaining an ultra-high rate of fire of ten rounds per second in automatic mode. With just a light pull of the trigger and several shots in a row, he fired dozens of powerful explosive rounds.

Equivalent to dozens of grenades, exploding densely thirty to forty meters behind everyone, instantly repelling twenty to thirty attacking mutated creatures and stopping the formation of the monster tide.

And the three thousand spare shells possessed by the rapid-fire cannon were enough to support Lin Feng and the others to run the three kilometers to the entrance of the fourth basement level.

At this time, as Lin Feng kept shooting backward, the four women behind him also came to the front of the team.

Lin Feng immediately ordered:

"Shen Yue, hold up the shield and clear the way! Chen Shanshan, help kill the attacking Tier 2 mutated creatures! A Lian and A Ming, provide left and right fire cover, repelling the mutated monsters that block the way or squeeze through."

The vibration and explosion just now awakened a large number of dormant mutated creatures. They were frightened and began to scurry around, and most of them just wanted to escape the unknown danger behind them.

They did not intend to attack Lin Feng's team.

That's why they had time to react and use the weapons at hand to cut a bloody path through the monster tide.

However, in the monster tide, there were also mutated creatures that had evolved to late Tier 1 or Tier 2, planning to take the opportunity to launch a surprise attack on such delicious prey as Lin Feng's team.

Now they could only rely on the four women to rush to the front, cooperating with each other to be prepared.

And the rolling monster tide rushing from behind the team would definitely be difficult for Zheng Yanying to deal with alone. Lin Feng had to step in to assist in order to prevent the team from being swallowed by the monster tide.

If they were swept into it, with thousands of mutated creatures bumping and biting them, even if everyone was wearing sealed battle armor, it would definitely be breached and infected.

To escape, Lin Feng and Zheng Yanying had to block the monster tide behind them, causing them to flee to both sides.

And the main road, as the widest road among the various levels of the ruins, naturally gathered many mutated creatures.

Fortunately, Lin Feng had powerful firepower. A rapid-fire cannon in his hand was equivalent to two fully loaded infantry fighting vehicles.

According to the sixty-millimeter mortar, with a rate of fire of thirty rounds per minute, one round every two seconds, while the rapid-fire cannon could fire ten rounds per second, that was twenty times the firepower.

Equivalent to Lin Feng alone, controlling twenty small mortars to strike the monster tide behind him.

In terms of firepower suppression, it was naturally more than enough.

In order to avoid exposing too much strength, Lin Feng only activated the Rapid Pursuit attribute at the beginning. After successfully repelling the surging monster tide, he switched to the ordinary one round per second, creating the appearance of limited ammunition.

At this moment, cooperating with Zheng Yanying's raised iron hammer, they repelled the surging monster tide to ten meters away.

Lin Feng was responsible for large-area strikes, while Zheng Yanying carried out targeted treatment of the fish that slipped through the net.

Under the perfect cooperation of the two fighting and retreating, they quickly helped the team retreat to the outside of the entrance to the fourth basement level.

The monster tide gathered by the mutated creatures behind them had already gathered continuously.

Because both the left and right sides were places where sources of pollution gathered, the panicked monster tide all blocked the entrance to the third basement level on the main road.

Relying solely on the rate of fire of one round per second in his hand, he could no longer stop dozens of mutated creatures from pouncing and biting at the same time. Lin Feng had no choice but to switch to Rapid Pursuit again, relying on the automatic mode's ten rounds per second for suppression.

Fortunately, the four people in front of Chen Shanshan had already successfully reached the stairwell with mutual cooperation.

Lin Feng and Zheng Yanying exchanged a glance, and after repelling the monster tide once again, they immediately turned around and ran towards the stairwell at the entrance.

During the escape, Lin Feng did not forget to raise his left hand and give the large group of mutated creatures that surged again behind him a few extremely powerful armor-piercing rounds.

These armor-piercing shells not only easily penetrated the flesh and blood of the mutated creatures, but also triggered the warhead fuse in the process of penetration, exploding instantly.

The huge damage of up to one hundred and fifty points, coupled with the explosion range that could cover a radius of ten meters, completely severely injured the twenty to thirty mutated creatures on the entire main road with just one shot!

The mutated creatures within a radius of two meters from the center of the explosion were directly blasted into pieces, with no possibility of resurrection!

Such power was already comparable to the army's 105mm howitzer in the Old Earth period, which was the basic starting model among heavy artillery.

Above, there was also the more powerful 122mm, which could cover a radius of twenty to thirty meters, equivalent to a basketball court; and the 155mm howitzer, with a kill radius of up to fifty meters or more, the damage range could even cover two entire soccer fields.

And this was also the main strengthening direction for Lin Feng to upgrade the level seventeen armor-piercing cannon in his hand later.

The pursuit of extreme damage was to achieve the effect of a one-shot kill.

Just like at this moment, with the armor-piercing cannon out, the hundreds of surging mutated monster tides also directly disintegrated in an instant.

They were deterred by the terrifying explosive power and sound.

For a time, scattered limbs and minced meat littered the entire main road, and nearby buildings were covered with the shattered mutated creature flesh and blood tissue...

The scene was so tragic and brutal that even the low-intelligence mutated creatures felt deep fear.

They scattered and fled, no longer daring to gather together to pursue Lin Feng's team.

Taking advantage of this opportunity, the six members of the team also successfully entered the entrance stairwell, climbed up thirty steps, and arrived at the third basement level above.

Shen Yue, walking in the front, saw a few bright lights emerging from the exit, and then instinctively raised the titanium alloy shield in her hand, squinting to observe.

Immediately after seeing the light clearly, it was the team left by the Savior Army on the third basement level, responsible for receiving them.

At this moment, upon this meeting, the other party also saw clearly that the escaped explorers were not their leader, and then asked about what happened downstairs.

How did Shen Yue and the others know the situation? They only said that an explosion occurred below, alarming all the mutated creatures on the fourth basement level. They also escaped death and saved their lives.

It was not until later that Lin Feng and Zheng Yanying ran out of the stairwell that the six members of the team took a temporary rest.

Carrying a hundred kilograms of battle armor and running wildly for three kilometers, while also dealing with the attacking mutated creatures everywhere, even the evolvers were a little exhausted.

Adding to the fact that everyone was already feeling slightly exhausted before, they now needed to rest for a while before continuing.

It was a good opportunity to use the entrance stairs on the fourth basement level to block the mutated monsters surging up from the lower levels.

The only ten-meter entrance, coupled with the concrete walls on both sides, allowed Lin Feng's rapid-firing cannon to exert its power to the fullest, maximizing the impact.

Just two consecutive shots could cover the entire stairwell, repelling more than a dozen mutated creatures crowding up, scaring them back to the fourth basement level.

The Salvation Army's rescue team, seeing the power of the gun in Lin Feng's hand, instantly calmed down from their original anxious state.

They realized the strength of the other party, especially Lin Feng in front of them, was definitely not someone they could interrogate.

So the captain quickly sent Lisa, who was standing at the back, to inquire about the situation.

Seeing Lisa approaching with a torch, Lin Feng fired into the stairwell behind him while saying:

"We really don't know the situation. We were just active and exploring within three or four kilometers of the entrance to the fourth basement level."

"The explosion came from below the fourth basement level, maybe the fifth or sixth level. Anyway, it was very powerful. You on the third basement level should have felt the tremors, right?"

Lisa nodded, looking worried:

"There was a slight tremor, and we could hear the sound of the explosion. However, in the upper three levels of the refuge ruins, the number of mutated creatures is small, only about a hundred or so on each level, so there hasn't been a monster tide like the one behind you."

Lin Feng hummed in agreement:

"I guess the Salvation Army's main force encountered some mishap while searching for the military factory below, and had to use a powerful explosive…"

"If they are confident in their strength, they should be able to escape after using the explosives to solve the problem."

"It's about time, we have to go."

"I suggest your team return to the surface first. A dozen or so mutated creatures running out from the lower levels are beyond what your weapons and equipment can handle."

"Moreover, the mutated creatures are already in a frenzy, all in a state of rage. Even the holy water we carry has lost its ability to dispel them. Relying on a few torches is useless."

After speaking, Lin Feng immediately signaled the few members of the team who had caught their breath to continue retreating to the upper level.

Mainly Shen Yue and A'Lian needed to rest for a while to recover their strength.

The former was holding a giant shield weighing several hundred kilograms, while the latter was weaker and couldn't withstand continuous high-intensity combat. As for Chen Shanshan, she was much more relaxed. During the retreat, she used the titanium gun in her hand to take down several attacking Tier 1 mutated creatures.

The demon-exorcising holy flame on her waist also had an excellent effect.

When the four women encountered a Tier 2 mutated creature, the demon-exorcising holy flame only needed one shot of two blasts to shatter it, along with the seven or eight Tier 1 mutated creature lackeys following behind.

The original base damage of 130, plus the additional 10 points of armor penetration, was 140 points. Adding the 100% bonus to mutated creatures after adding holy water, it became 280. Then, with two gun barrels, one shot of two blasts…

A total of 560 points of damage could be dealt!

Even a Tier 2 mutated creature in the early to mid-stage could be seriously injured with one shot and taken down with two!

It was precisely with the help of the demon-exorcising holy flame's terrifying damage that the four women's retreat was so smooth.

Now that Shen Yue and the others had caught their breath, Lin Feng immediately ordered them to continue retreating.

In any case, they had to escape the refuge first.

Chen Shanshan nodded, obeying Lin Feng's orders, and then led the three women behind her to continue fleeing towards the exit on the third basement level in the distance.

She believed in Lin Feng's ability to hold off the rear. If even Lin Feng couldn't cope with the monster tide crisis behind them, then the entire team… would be buried here.

As the women left, Lin Feng glanced at Lisa and the Salvation Army team standing behind her, and then followed Zheng Yanying's footsteps, walking at the end of the team.

Even if they reached the third basement level, waiting for everyone above was still a long trek of twenty-five kilometers!

The only good thing was that there were no Tier 3 contamination sources in the upper three levels, and there was no need to worry about attacks from Tier 2 mutated creatures. Even the number of Tier 1 mutated creatures was very small.

Everyone no longer needed to deliberately maintain a retreat formation. Their tense nerves could finally relax a little.

After Lin Feng's team left, the remaining Salvation Army support members looked at each other.

Until the captain saw the mutated creatures in the stairwell behind him, gradually eager to move because of the loss of artillery suppression, he hesitated for a few seconds before ordering them to follow Lin Feng's team and withdraw from the refuge ruins together.

The long trek of twenty-five kilometers was even longer than a half marathon. Fortunately, everyone was an evolver, and they didn't have to worry about attacks from mutated creatures on both sides, so they rushed to the second basement level in one breath.

Then, without stopping, they continued to rush forward.

Everyone was holding their breath in their hearts, gritting their teeth and not letting go.

Fortunately, the further they went, although it became hotter and hotter, the environment was no longer as harsh as it was below. The whispers in their ears and minds gradually dissipated, and there was not so much bacterial mucus and black mist nearby.

Until they entered the first basement level, the line of sight became slightly brighter, changing from darkness to dimness, no longer like the previous fourth basement level…

Pitch black, so dark you couldn't see your fingers.

At this time, everyone had already run more than twenty kilometers in one breath, from the fourth basement level to the first basement level.

Except for Lin Feng, the remaining three, including Zheng Yanying and Chen Shanshan, showed signs of physical exhaustion.

After all, wearing hundreds of kilograms of battle armor was not powered armor, and they needed to resist it themselves. In addition, there were the weapons and ammunition prepared in their backpacks, as well as the thirty kilometers they had already walked before the monster tide occurred, and the exploration of the contamination source on the right side of the fourth basement level…

A series of actions were constantly consuming physical strength.

Even powerful Tier 1 mid-stage evolvers like Chen Shanshan and Zheng Yanying couldn't withstand such high-intensity combat.

Equivalent to a thirty-kilometer forced march, plus a twenty-kilometer breakout battle, and having to carry a body of heavy armor, focusing their attention throughout…

So after arriving at the first basement level, except for Lin Feng in the late stage of Tier 1, the remaining five were already overwhelmed.

Among them, Shen Yue was panting the most. She was holding a titanium alloy shield weighing several hundred kilograms, nearly a ton, plus the armor on her body, which was the heaviest load in the team.

Even though she had the strength of the mid-stage of Tier 1, she was bearing a load ten times her weight, running the entire distance…

If it weren't for her special physique-type digestive ability, which could provide a long-term berserk state, she would have been exhausted halfway.

Apart from her, A'Lian and A'Ming were also approaching their physical limits, sitting on the ground with a thud or lying down, coughing violently, and having some difficulty breathing.

At this time, Zheng Yanying supported herself with a war hammer and said to Lin Feng:

"We've already run more than twenty kilometers, let's rest for a while. Even if there is a monster tide, there are very few that can reach here. Ordinary Tier 1 mutated creatures, even Tier 2, pose a very low threat to us."

"Let's rest for ten minutes before leaving."

As soon as these words came out, they were unanimously approved by the women.

Lin Feng frowned slightly. What he was worried about was not Tier 1 or Tier 2 mutated creatures, but the crisis targeting the Salvation Army's main force, which was likely to be a stronger and more terrifying existence than Tier 2 mutated creatures.

Thinking of this, Lin Feng looked at the stairwell behind him, where explosions were heard from time to time, while calming his breathing…

He slowly said to everyone:

"According to our previous analysis and the introduction when Pastor Zheng came, the Salvation Army has at least two Tier 2 evolvers, one of whom is quite strong, at least in the mid-stage of Tier 2."

As she said this, Zheng Yanying gradually reacted, her face under the mask flushing, and her expression changed.

Lin Feng continued:

Think about it, what kind of enemy could force such a strong, second-rate wandering force to use extremely powerful explosives?

Zheng Yanying sighed softly beside him:

Then it can only be the third-order aberrant bodies gathered from the bottom of the shelter... from third-order sources of pollution...

Lin Feng nodded:

We can still rely on the special anti-magic effect of holy water to severely damage or eliminate second-order aberrant bodies, as long as we react in time...

But once we face third-order aberrant bodies, even if they are far from true third-order kings, even possessing one-tenth of a king's power is something our first-order team cannot resist.

Zheng Yanying nodded, picked up the warhammer propped on the ground, and slowly echoed:

Lin Feng is right, I was inconsiderate. The enemy is likely to be a third-order aberrant body, or a late-stage second-order corrupter. We can't afford to provoke either of these right now.

Let's go, it's only the last five kilometers. The two minutes of rest we just took are about enough.

Hearing about the existence of third-order aberrant bodies, the four women on the ground were immediately filled with fear, and could only endure the soreness and fatigue all over their bodies, gritting their teeth and struggling to stand up, following the pace of Zheng Yanying and Lin Feng, and continuing forward.

As the group continued on their way, after walking two or three kilometers, they finally saw the remaining light shining down from the ground staircase!

The sunlight they once hated was now like quenching thirst with plums, representing the hope of survival.

The painful and ferocious expressions under the masks of the crowd also showed a look of longing.

Zheng Yanying then spoke, cheering everyone up. As a combat priest, boosting her teammates was also her duty.

So, she began to explain that the aberrant bodies chasing behind them could not leave the underground ruins.

To be precise, they cannot leave the dark environment.

Because when they enter the extremely dry surface, or are exposed to the sun, their slippery skin will directly crack, and their body temperature will rise rapidly. The strong ultraviolet rays will burn and kill the aberrant cells that make them up.

The genetic radiation of the ruins is a curse, but in the face of the blazing sun, once they leave the dark environment, the strength of the aberrant bodies will plummet instantly, turning into lambs to be slaughtered...

So, as long as they escape to the surface,

they can be safe!

Encouraged, everyone burst out with strength again. The physical fitness of the evolvers, even after being overdrawn, still had the strength to continue squeezing out.

Even though they were carrying hundreds of kilograms of heavy armor and had been running for over twenty kilometers, after seeing the hope of survival, they relied on their last willpower, and everyone ignited a raging fighting spirit!

They quickly ran towards the final staircase leading to the surface, two kilometers away.

The soreness and swelling of their feet gradually subsided with the excitement...

Losing sensation, they ran faster and faster.

It took a total of ten minutes for the group to run five kilometers and reach the long staircase they had descended from.

Looking up, they could already see the mountain cave where the sunlight was shining in, beckoning to them.

Unfortunately, after reaching this point, it was difficult for Shen Yue and the others to climb up the steps.

Lin Feng had no choice but to help them up one by one, running back and forth four times.

Finally, it was Zheng Yanying's turn to guard and be vigilant.

The latter waved his hand:

I can do it myself, you watch the rear.

Lin Feng nodded and followed behind her, stepping up the steps one by one, walking towards the exit above.

Just halfway there, they heard a loud bang!

A violent explosion came from the entrance of the second basement level behind them, the vibration and sound level being more intense than the armor-piercing cannon in Lin Feng's hand.

Lin Feng immediately turned his head to look.

He saw the sound of frantic footsteps approaching from three or four kilometers away, heading towards the entrance.

Zheng Yanying's expression changed slightly, recalling that if Lin Feng hadn't insisted on everyone continuing forward ten minutes ago, they would have been the ones being chased now.

Let's go, don't look.

Lin Feng's faint words came from behind.

Zheng Yanying nodded and continued to step forward.

When she arrived at the exit, the others who had already taken off their level three helmets grabbed Zheng Yanying out of the cave.

Back on the surface, they lay on the ground, taking off their masks and breathing in the fresh air.

Although the mask had a breathing filter system that provided clean air, the air in the old space of the fourth basement level was not only full of bacteria and viruses, but also smelled very bad.

Even if the air filter could filter out the large molecular gene proteins of the viruses, it could not remove the smaller-level odors.

Moreover, the oxygen content of the air in the underground shelter itself was very, very low, and they needed to suck hard to get the oxygen they could normally breathe on the surface.

Now that the danger was lifted, everyone lay on the ground, revealing long-lost smiles.

But soon Zheng Yanying realized something was wrong...

Lin Feng, who had climbed up with her,

had not walked out of the nearby shelter ruins!

Zheng Yanying immediately stood up and came to the edge of the cave, seeing Lin Feng still standing on the steps near the entrance, looking at the explorers rushing from afar.

It was the Salvation Army team.

More precisely, it was the Salvation Army's main force, leading a support team, rushing towards the cave at top speed.

Behind their group, there were countless aberrant bodies, including quite a few second-order aberrant bodies.

The leading monsters in the front row of the monster horde were quite large, especially the one in the very front, which was more than four meters tall.

Because the distance was too far, and the sight in the dim space of the first basement level was limited, they could only vaguely see the humanoid monster wearing black armor, closely chasing behind the Salvation Army, through the lights in the hands of the Salvation Army.

And in the Salvation Army team, running in the front was a white-haired woman wearing light armor.

She was also carrying the exhausted Lisa in her hand.

While running for her life, she pulled out a bottle from her waist and threw it towards the monster horde behind her.

Then the steel bottle, less than the size of a forearm, exploded with a bang, unleashing a power even greater than an armor-piercing cannon.

But because it was just a simple explosion, without speed and precision, it was easily dodged by the large aberrant body that was closely following behind, as well as several late-stage second-order aberrant bodies.

Seeing that this group of powerful aberrant bodies was about to catch the main force of the Salvation Army, Lin Feng hesitated for two seconds...

and slowly raised the armor-piercing cannon in his hand.

Activating the firepower coverage attribute, it could fire six armor-piercing cannons with 140 points of damage per second, for five seconds continuously.

Lin Feng only pulled the trigger twice!

Twelve powerful armor-piercing cannons shot straight from the muzzle, half a fist thick, towards the locked target:

the group of powerful aberrant bodies behind the Salvation Army!

Only a series of rumbles were heard!

It was as if several cannons were firing simultaneously, bombing a thousand meters away.

The relentless monster horde was instantly severely damaged by the artillery fire, stopping and scattering.

Just three or four seconds of interception successfully created distance between the Salvation Army and the monster horde, giving them a chance to escape.

Seeing that the goal was achieved, Lin Feng only glanced at the people in the Salvation Army who were staring at him, then turned around and left the cave.

Let's go, it's time to go back and eat.
