End of the World: My Items Can Be Upgraded Infinitely

As Lin Feng activated the flight mode of the lv20 Flying Tiger Armor, he flew backwards relying on the inertia of retreat.

The soil pile at the entrance of the wormhole, which had been hiding, collapsed in an instant, revealing a loose deep pit.

While the mud and sand were constantly flowing due to high-frequency tremors, a ten-meter-long giant jaw, almost at the same time, suddenly broke out of the ground from where Lin Feng was before, like a stab!

With a click, it closed and cut off!

The sharp barb at the tip of the giant jaw was only a few centimeters away from the tip of Lin Feng's toes after he took off.

Fortunately, he reacted quickly. If he was a few microseconds slower, his feet would definitely be in danger and he would be seriously injured.

Because of the activation of the Eye of Death, Lin Feng entered a state of full concentration, especially when he pulled the trigger at the last moment, his attention ignored the changes in the soles of his feet.

A large number of red beetles used their chelicerae to insert into the cave wall, and then began to shake in unison.

It was exactly the same as what Lin Feng had encountered in the dormitory building in Haicheng.

At the beginning, the red beetle group knocked on the ground wall together to summon its kind to come...

And at this moment, their consistent behavior is to use rapid vibrations with synchronized frequencies to destroy the stability of the soil structure, so that the soil on the cave wall becomes like quicksand, allowing the nearby tiger-backed worms to quickly swim through the cave.

When the vibrations reached Lin Feng, it was at the last moment that he discovered the changes under his feet in time, and there was no time to upgrade the lv19 howitzer that completed the kill.

Lin Feng directly retreated several steps and soared into the air.

The tiger-backed worm stretched out a pair of giant jaws and found that it could not bite the target, so it slapped back heavily, trying to injure Lin Feng.

It must be said that the tiger-backed worm, as a cross-level upgraded version of the black-backed worm, not only has a qualitative leap in physical attributes, but its IQ has also been improved, which is completely worthy of the dozens of points of spirit value.

If Lin Feng did not obtain the ability to fly, it would not be so easy to avoid this crisis.

And as he soared into the air, the lv19 howitzer in his hand had already aimed at the quicksand cave below!

The shells were fired like flowing water!

Under a series of explosions, the tiger-backed worm quickly hid deep in the tunnel, but the red beetles that helped it build the quicksand river were not so lucky.

The howitzer with a damage of up to 190 points, the shock wave generated by the explosion directly killed them.

So the tremor stopped, and the fluid-like soil gradually stabilized.

Even if the tiger-backed worm lost its breakthrough point for attack, Lin Feng still pulled the trigger until he blew a more than ten-meter deep pit in the sunken pit under his feet, and then stopped the bombing.

Fortunately, the tiger-backed worm ran fast, and it was protected by the soil, and the hardest giant jaw was facing upwards, so Lin Feng fired dozens of shots in a row, but only caused nearly 100 points of damage.

For the tiger-backed worm, it was not even a serious injury.

It was a pity that it was let go.

Lin Feng groaned and spit out a yellow sputum on the ground.

It was full of mud and sand, which was the flying dust inhaled when he retreated and shot violently before.

After using telepathy to confirm that there were no tiger spine worms nearby, Lin Feng decided not to stay any longer and gave up the idea of ​​going to the cave where the tiger spine worms died in the distance to check the bodies.

Qin Hu's experience was still vivid in his mind.

Even if Lin Feng had the protection of the Flying Tiger Armor, he did not want to take the risk of fighting with the Zerg in the cave for the corpse.

If he was besieged by several tiger spine worms, his lv19 howitzer alone would not be able to cope with it.

With a flash of light, within fifteen seconds, Lin Feng maintained an altitude of fifty or sixty meters and flew back to the outpost fortress.

At this moment, many new recruits who were watching, as well as Li Ran and others, were stunned.

With Shen Jie's reminder, they already understood that the humanoid creature wearing black and yellow flying armor who broke into the heart of the Zerg was their sergeant, Lin Feng.

When the familiar explosion sounded, Li Ran and others who raised their telescopes to observe, cheered for the death of the tiger spine worms, and also clenched their palms for Lin Feng who successfully avoided the Zerg counterattack at the critical moment.

At this moment, the sergeant returned victoriously, waving his membrane wings and landing steadily next to the chariot in the center of the outpost.

Li Ran, Shen Jie and others came over, and after the smoke and dust cleared, they saw the familiar face in the black and yellow flying armor unfolding the facial armor, and they were immediately overjoyed.

Ninety percent of the combat effectiveness of the outpost bunker comes from Lin Feng himself, and the stronger Lin Feng is, the greater the chance of their success in defending.

Whether it is the unique flying ability it shows, or the means of fighting against or even killing tiger spine worms... it can greatly alleviate the deterrent pressure brought to the defenders by the second-level Zerg.

Morale is a very important thing.

Especially in long-term battles, losing morale means that the combat effectiveness of the team will plummet.

This psychological factor can sometimes even determine the outcome of a major battle.

And Lin Feng's record of going deep into the Zerg hinterland, not only killing a tiger spine worm, but also retreating unscathed will undoubtedly greatly encourage the soldiers of the outpost and no longer fear the more difficult battle tonight.

Because they are led by the sergeant.

Even if the tiger spine worm attacks, there is nothing to fear.

Facing the gazes of Shen Jie and others, as well as the expectant eyes of many soldiers in the shooting layer on the wall, Lin Feng said lightly:

"I have successfully killed a tiger spine worm and will soon enter the second stage of awakening. Disperse, I need to have a good rest and complete this awakening before night falls."

Hearing the confirmation from the sergeant, everyone cheered!

The awakener of the second stage is a powerful existence picked out of thousands...

Not only will the superpowers have a qualitative leap, but the combat power will also be greatly improved.

For example, Major Cheng, who returned unexpectedly, was promoted three levels directly because he successfully advanced to the second-level awakening, becoming the only awakener with the rank of colonel.

But he is only an awakener with enhanced physique.

And Sergeant Lin in the outpost at this moment is a famous super-powered bullet awakener!

Once the superpower is further improved, it is estimated that he can kill tiger spine insects remotely and directly bomb the insect tide army.

As Lin Feng waved his hand, he walked into the chariot under the attention and expectation of everyone. The excitement filled the outpost for a long time.

Chen Yanyan stood up from the driver's seat and saw Lin Feng take off his full body armor and reveal his true body. She breathed a sigh of relief and smiled as she stepped forward to help Lin Feng take off his short-sleeved pants that were already soaked with sweat.

Continuous flight would cause the Flying Tiger Armor to overheat, and the sudden increase in heart rate and adrenaline in the previous life-and-death crisis made Lin Feng sweat all over.

Easily invincible is shown to outsiders.

Only Lin Feng himself knows the real danger.

"Didn't you detect any traces of flying insects?"

Lin Feng took the dry towel handed by Chen Yanyan, wiped the sweat from his forehead, and asked.

Chen Yanyan shook her head:

"I didn't detect the existence of wind-winged insects, but there were a few green-winged insects, and one was hiding in the distance and watching, and never approached."

"They will probably go back to inform the queen of the Zerg, and the next time they go out of the city to fight, it won't be so easy..."

Lin Feng nodded. The flying mode of the Flying Tiger Armor could not be hidden for too long. From the beginning, he planned to use it to exchange for equipment upgrades.

Now that this goal has been successfully achieved, Lin Feng, who has been upgraded to lv20, has corresponding solutions even when facing the harassment of wind-winged insects.

And the flying mode is only the variant form of the Flying Tiger Armor, and one of them is an auxiliary form. The remaining two, whether it is absolute defense or explosive scale armor, can effectively resist wind-winged insects.

"Then you continue to monitor. I need a period of awakening and cannot be disturbed."

As he said this, Lin Feng frowned slightly, his eyes deep:

"If during this period, the Zerg launches a general attack and several tiger-backed worms are preparing to attack the city, you can directly press the detonator of the explosives on the road and drive away from here."

"As for the others, take them if you can."

Chen Yanyan took a deep breath and nodded solemnly.

As the awakening unfolds, Lin Feng will definitely lose his combat effectiveness for a period of time, and this will also be the most vulnerable and dangerous moment of the outpost.

As the person Lin Feng trusts most, he must make a decisive decision when necessary, abandon some of the defenders, and protect Lin Feng from escaping the outpost.

Seeing the detonator Lin Feng put on the table, Chen Yanyan watched him walk into the bedroom and then returned to her post.

Confirm that the tiger-backed worms did not come and retaliate.

In the bedroom, Lin Feng turned on the upgrade of the lv19 howitzer, then walked into the bathroom, washed off the sweat on his body, and at the same time washed off the arm guards covered with dust and mud.

After washing and walking out of the bathroom, Lin Feng ate some compressed biscuits, chocolate and other high-calorie foods. When he felt full, he lay on the bed and waited quietly for the completion of the howitzer's cross-level upgrade.

It was only half past one, and there were still about five hours before dark, so it was completely in time.

What I told Chen Yanyan before was just the worst possible possibility with a very small probability.

If the queen mother had a little bit of brains, she would not launch an attack during the day when she knew that the sentry had the ability to kill the second-level Zerg.

It was the best decision to retreat and make plans.

And soon, after an hour of cross-level upgrade, the lv19 howitzer successfully entered the orange quality.

"Armor-piercing cannon lv20/29, orange quality"

"Damage 250, effective range 10 kilometers, remaining bullets 6000/6000"

"Additional attributes: bullet recovery 1/s, space magazine 6000 spare bullets, Death Eye 0/50, firepower coverage damage 50+50/s, coverage area 10,000 square meters"

"Additional attribute added: bullet time"

"Evaluation: This is an armor-piercing cannon with the ability to penetrate a hundred millimeters of defense layer. Its powerful penetration makes it difficult to maintain its narrow gun body, but the changing form can better exert its long-range combat power. The enhanced shells can penetrate ten meters deep soil layer through multiple energy additions. Hitting the target can cause internal explosion damage, which poses a serious threat to targets with extremely high armor values."

Looking at the orange light flashing in his hand, the lv20 armor-piercing cannon transformed from a pistol to a rifle, Lin Feng could already feel its weight increasing exponentially.

Don't look at its appearance at the moment, it looks like only a dozen pounds, the actual weight is as high as hundreds of kilograms, but in the hands of a first-level perfect awakener who can swing his arm with several tons of force, the weight of a hundred kilograms is no different from the wooden stick in the past.

Lin Feng can still aim the gun with one hand at will, and after the upgrade, it is also equipped with a matching scope, which can be switched from 4x to 8x at will.

And more importantly, this scope can superimpose Lin Feng's eagle eye vision as an awakener.

In other words, its actual observation and aiming distance is within eight kilometers.

Like small rockets and anti-tank missiles, Lin Feng's actual combat distance has increased several times.

But it seems that there is no night vision mode...

It will still be greatly discounted at night.

But this upgrade directly increases the basic damage by 60, which makes Lin Feng very addicted.

250 points of basic damage, combined with the Eye of Death, the headshot is doubled, even the lv25 tiger spine insect will be killed on the spot.

As for the reserve bullets, it has increased by 1,000, and there is no actual change in other aspects.

Lin Feng continued to look down and saw the new additional attribute he had been missing:

Bullet time...
