Wasteland: My items are infinitely upgraded

Carrying nearly 500 milliliters of evolution fluid, Lin Feng returned to the camp to begin his final small-scale evolution before advancing to the second stage.

Completing the level 19 evolution meant that the first-stage cells in his body had reached their limit. From now on, there would only be quantitative accumulation, with no more qualitative breakthroughs.

Inside the Rock Horse chariot, Lin Feng looked at the Leader-grade Rockhorn Horse life essence in his left hand and the level 17 filter in his right, lost in thought.

Currently, the maximum pore size of the essence filter had shrunk to about twenty nanometers. With just one more level, it could filter second-stage essence!

When that happened, the filtration conditions for third-stage essence should also appear. If successful, it would mean that Lin Feng's evolution resources for the next few years could be solved by the secondary processing of the essence filter.

After purifying and filtering the level 19 Rockhorn Horse essence in his hand, obtaining a full cup of pure essence, Lin Feng first consumed five points of life force to continue upgrading the filter.

Then, he ate a piece of dried cooked meat to restore his life force, while also providing sufficient energy for the upcoming evolution.

"Lin Feng, lv19 / 19"

"Life Force: 150, Physique: 150, Spirit: 149; lv19 attribute limit 150"

"Superpower Awakening: Imprint Power (slightly increases the enhancement and upgrade speed of imprint equipment)"

"Item upgrade limit increased to lv19!"

"Can consume 5 points of life force to continue upgrading lv18 machine gun, lv18 rapid-fire cannon, lv18 essence filter"

Lin Feng narrowed his eyes slightly, then checked the level 18 essence filter that had been upgraded aside:

"Nano-scale Essence Filter lv18, Red Quality, Imprint"

"Basic Attributes: Maximum Pore Size 10 nanometers, First-Order Genetic Impurity Filtration Rate: 100%; Second-Order Impurity Filtration Rate 100%; Usable Times 1; Can consume five points of life force to upgrade"

"Evaluation: Can perfectly filter heterogeneous genetic impurities in first-order and second-order life essence to obtain pure essence for flawless evolution; Filtration rate of third-order life essence is limited, requiring a maximum pore size equal to 1 nanometer to completely filter impurities."

Although he achieved the expected effect, Lin Feng wasn't very happy because the third-order essence level actually required less than one nanometer!

This meant that its pore size had to reach the atomic level.

Lin Feng remembered the chemistry he had learned a long time ago, which introduced that the most basic unit of matter, the atom, was between one nanometer and one picometer in size.

One millimeter is equal to one thousand micrometers, which is the size of a single cell or bacteria.

One micrometer is equal to one thousand nanometers, which measures chromosomes, viruses, and some large protein molecules.

And one nanometer is equal to one thousand picometers, which is the scale for measuring the size of atoms.

The specific size depends on the mass of the atomic nucleus, or more precisely, the number of positively charged protons, which determines the number of electrons in the atom, thus affecting the size of the atom.

A small hydrogen atom is about 0.1 nanometers, or one hundred picometers, while other large-mass atoms are around several hundred picometers.

Therefore, a pore size less than or equal to one nanometer can definitely filter out all impurities.

Of course, some small molecules can also pass through, but ribonucleic acid containing genetic information will definitely be blocked, ensuring that the filtered life essence is absolutely pure.

However, this was also what Lin Feng was worried about.

Originally, he thought that the pore size capable of filtering third-order essence would be at most ten nanometers or less, and upgrading to level 19 should be sufficient.

Now it seemed that less than one nanometer was necessary to be safe, so the level 19 filter definitely couldn't meet the requirement. At least a second-order orange quality equipment was needed to completely filter the impurities.

Therefore, before advancing to the second stage, unless he used the imprint's forced upgrade skill, at the cost of consuming one of his own evolution levels, the filtration of third-order essence would be a distant prospect.

He hoped Bai Ye would keep his promise.

After clearing the negative third floor, he would hand over the Chieftain-level Rockhorn Horse's second-order essence to him.

Otherwise, Lin Feng would never have agreed to accompany them below the negative third floor.

According to what they had said before, the military factory was likely on the negative sixth floor or even further down, where various dangerous sources of pollution were abundant.

Moreover, after the pollution sources accumulated, they would give birth to third-order Aberrant Kings.

With the Salvation Army opening the sealed door, who knew if only one third-order Aberrant would run to the upper and middle layers of the ruins.

At that time, without the strength of second-stage evolution, Lin Feng would definitely run away with the Church's team first.

After making his plans, Lin Feng ate evolved jerky while giving the rapid-fire cannon and armor-piercing cannon their final upgrade before the second stage.

Soon, according to the established upgrade and enhancement strategy, both heavy weapons were fully upgraded:

"Rapid-Fire Cannon lv19, Red Quality, Imprint"

"Basic Attributes: Damage 120, Effective Range 2 kilometers, Kill Coverage 8 meters, Remaining Burst Rounds 4000; Upgraded to host's level limit"

"Additional Attributes: Ammo Recovery 1 / 1s; Space Magazine 4000 rounds; Area Damage (coverage radius 8 meters, 120 damage at the center 1 meter); Extreme Pursuit (automatic mode ten rounds per second)"

"Note: Can freely switch back to lv9 Excellent AK"

After being upgraded to the second stage's maximum level, the rapid-fire cannon had a total of four thousand rounds of ammunition. The entire gun gradually upgraded from the original Excellent AK sample to the current heavy machine gun state, which was more than one and a half meters long.

The barrel alone was more than one meter long, and the inner diameter reached more than thirty millimeters. With four thousand rounds of ammunition, the weight had already exceeded one ton.

Now, Lin Feng, who had evolved to level 19, although he had nine tons of basic strength, could only perform single-shot bursts while holding it in one hand.

If he turned on the automatic mode of Extreme Pursuit, unless it was purely for fire suppression, he could only ensure accuracy by holding the gun with both hands, with his left hand assisting in pressing down the gun.

The recoil of continuous fire could not be suppressed with one hand.

Of course, the best use of the level 19 rapid-fire cannon was actually to mount it on a chariot on a mobile platform to provide long-range fire support and strikes.

It was a bit too overpowered for an evolver to use directly. Perhaps ten evolvers with gun abilities could not compare to this top-level rapid-fire cannon.

The number of rounds Lin Feng revealed to Bai Ye was three to four hundred, only one-tenth of the real ammunition.

Therefore, no matter what, the Salvation Army would never guess Lin Feng's true strength.

Now, let alone thousands of Aberrants, even tens of thousands, Lin Feng could rely on the narrow terrain advantage of the staircase to carry out dense fire blockade.

Four thousand rounds of rapid-fire cannon with a damage coverage radius of eight meters, one round could effectively kill seven or eight flesh-and-blood Aberrants.

Its sustained firepower intensity, combined with the characteristic of no durability wear under the power of the imprint, could reach an incredible level!

As for the upgraded armor-piercing cannon, because the damage had already reached the upper limit of the second stage, Lin Feng optimized its bullet recovery speed according to the previously established enhancement direction:

"Armor-Piercing Cannon lv19, Red Quality, Imprint"

"Basic Attributes: Damage 150, Effective Range 2 kilometers, Kill Coverage 12 meters, Remaining Tungsten Core Armor-Piercing Rounds 400; Upgraded to host's level limit"

"Extra attributes: Ammo regeneration 1/1min; Spatial magazine 400 rounds; Area damage (coverage radius 12 meters, 2-meter center deals 160 damage); Firepower coverage (six shots per second for five seconds); Armor-piercing rounds (armor penetration increased by 100%, damage +10)"

"Note: Can freely switch back to lv9 precision pistol"

Now, the armor-piercing rounds have 400 rounds in reserve, enough to inflict devastating blows on 400 Tier 2 Mutants, the firepower is already strong enough.

In addition, with the ammo regeneration speed of one round per minute, he can rely on another rapid-firing gun to provide suppressing fire during usage gaps to regenerate the armor-piercing gun's ammo.

Alternating between the two, Lin Feng felt that as long as he had enough time, he alone, with the cover of other members of the team, could solo the upper six floors of the ruins' restricted area.

And then block the Tier 3 Mutants at the entrance to the -7th floor.

It's just a pity that time is tight, and there's also the Salvation Army, who are determined to enter the bottom three floors, forcing Lin Feng's cleanup plan to be a little more restrained, first listen to their arrangements to obtain the evolution serum, and then consider collecting Wasteland Wolf Source.

After checking the two weapons, the upgrade time of the nano-source filter was relatively long, and no reminder had popped up yet.

At this time, it was exactly twelve noon, and Ding Yi's call came from outside, it's time for lunch.

The noon meal was eaten together by everyone.

Ah Lian and Ah Ming, who had entered the ruins for the first time and returned safely, finally woke up after sleeping for nearly twenty hours in one breath.

The weirdness and horror inside the ruins caused the two's mental state to decline sharply, but fortunately, after resting for so long, they have recovered somewhat.

After learning about the current situation and that they had no tasks, the two looked at each other and breathed a sigh of relief.

For the two of them, who were only in the early stage of Tier 1, the exploration mission of the ruins was still too dangerous. A slight carelessness could lead to their death, and then being eaten by the Mutants, or gradually becoming Corrupted.

But in Lin Feng's opinion, it was more useful for them to stay and protect the convoy camp than to follow and drag them down.

After all, the dried meat in the transport vehicle was the foundation of this mission and the team's most important supplies.

One hundred pieces of Level 18 dried meat, after Lin Feng evolved two levels in one breath, were consumed, leaving only ninety pieces. The main reason was that the upgrade of the source filter consumed nearly fifty life points, directly from level nine to level nineteen.

In addition, the physical exertion after continuous combat must also be replenished in time to restore physical condition, so the consumption of stored evolution meat was very fast.

These late-stage evolution meat, including the mid-stage evolution meat in Chen Shan's hand, and the ordinary evolution meat that the other five team members eat daily, are worth nearly 100,000 points in total.

Lin Feng was really worried about leaving only Liu Mingfei and the two girls, Liu Qian and Ding Yi, to guard.

If Ah Lian and Ah Ming were added, there would be a total of three combat members, enough to defend the camp and the war chariot.

Especially with the Level 9 AKs in their hands, which can fire Liu Qian's enchanted bullets, even if a Tier 1 late-stage evolver attacks, they can deal with it.

At this time, the two girls who had woken up were cooperating with Ding Yi to make a hearty lunch.

Having slept for almost a whole day, they were already hungry.

So a big meal was soon placed on the table.

Seven people sat together under the tent, ready to eat.

Lin Feng specially called the opposite church team over, anyway, there were only three of them, and they couldn't eat much.

But not Shen Yue.

So before the official meal, Lin Feng directly divided the large pot of stewed groundnut horse meat on the table equally into ten portions, ensuring that everyone could eat their fill.

So when Shen Yue walked over wiping her saliva, she found that there were only ten sets of tableware on the table, and the stewed groundnut horse meat had already been divided equally. Except for some vegetables and seasonings, there was no trace of other horse meat.

The joy and smile on her face disappeared by more than half.

Fortunately, ten kilograms of early-stage evolution meat were used this time, ensuring that everyone could get two jins.

But this Shen Yue, from the beginning of the meal, had finished a large bowl in less than five minutes, devouring it like a whirlwind.

Seeing her looking at others eagerly, having to mix the nutrient solution with vegetables to make a salad, looking helpless, Lin Feng rolled his eyes and handed her his bowl.

Lin Feng mainly tasted the flavor. No matter how much Tier 1 early-stage evolution meat he ate, it had very limited replenishing effect for him, who had already advanced to Level 19.

It's better to let Shen Yue eat more, which can also make full preparations for the next cleanup mission on the -3rd floor.

When everyone was about to finish eating, Lin Feng said:

"The Mutant cleanup work in the ruins has progressed to the -3rd floor. After the -3rd floor is cleared and we enter the -4th floor, our Wasteland Wolf Source collection mission will soon be completed."

"At the latest, there will be results on the fourth day, and I think it should be possible to collect everything on the fifth day."

The Salvation Army is very anxious now. They, like Lin Feng and the others, need to catch up with the progress, knowing that time is running out.

Now it is already the third day, and there are only seven days left before the scorching sun descends behind them.

Everyone nodded, sighing at the impermanence of the world.

They didn't expect that they would eventually need to rely on the Salvation Army's strength to find the Wasteland Wolf Source crystal and complete the mission.

Shen Yue then spoke, asking about the key point:

"When the Wasteland Wolf Source crystal is collected, if you still want to continue to stay and protect the Salvation Army's transportation of military equipment, we and our party must return in advance."

"The Oasis is urging us tightly, you know the reason."

"You can send a few people to drive an electric car all the way to protect the source crystal, and after arriving at Oasis Town, find Father Su An to exchange for the reward."

Lin Feng hummed and looked at Chen Shanshan beside him:

The latest novels are first published on 69shu.com!

"No problem, I will arrange it at that time."

Zheng Yan Ying nodded. As long as Lin Feng was still willing to continue to cooperate and fulfill his agreement with the Church and Father Su An, everything else would be easy to say.

After discussing this matter, the meal was almost finished.

It was only half past twelve, and there were still two and a half hours before three o'clock in the afternoon, so Lin Feng returned to the car to continue sleeping and recover his energy.

This cleanup operation on the -2nd floor lasted a total of eight or nine hours. Although Lin Feng only needed to pull the trigger and carry out remote bombardment, he still had to walk non-stop along the way and guard against the surprise attacks of Tier 2 Mutants, so the mental consumption was still not low.

So resting for two hours now can also make sufficient preparations for the upcoming battle on the -3rd floor.

On the other side, Chen Shanshan and Shen Yue, who were full and satisfied, also went to sleep.

The remaining few were maintaining their weapons and equipment.

Two hours passed quickly.

Lin Feng, who had set an alarm, woke up on time at half past two, and looked at the upgraded level 19 source filter. The maximum aperture was only reduced to one nanometer, which could only filter out 99% of the impurities in the Tier 3 source.

It was just the last bit.

As Lin Feng expected, to obtain the technical ability to filter Tier 3 source, he had to upgrade to at least Tier 2 orange quality.

However, he can now perfectly filter all impurities in Tier 2 source, obtaining pure life source.

Allowing Lin Feng to successfully achieve Tier 2 Immaculate Evolution.

This also means that even if he cannot advance to Tier 3 King in the future, Lin Feng will have two more opportunities to change his evolution path, either choose to join a top force in the wasteland and become a believer of an existence above Tier 3, or directly undergo xenogeneic evolution…

In short, the more pure and immaculate he keeps himself, the more evolution paths he can choose in the future.

But unless he is in a desperate situation, Lin Feng will definitely still be like Bai Ye, walk out of his own evolution path and become an independent Tier 3 King, without being subject to any constraints or restrictions.

Of course, if there is a chance, Lin Feng would also like to see what the evolutionary path after the third level would be like.

Is the end of evolution to become a truly ultimate life form, or a great and eternal god?

But before that, let's advance to the second level first!

Lin Feng then took his weapons and equipment, got up and walked out of the Rock Horse chariot, came to the camp, and put on the sealed armor.

At this time, Chen Shanshan was already ready, and Shen Yue on the other side was also awakened by Zheng Yanying and was about to finish packing.

Ten minutes later, the three of them, having prepared everything, walked towards the cave entrance at the foot of the mountain not far away.

The Salvation Army members in the cave, after eating lunch and resting for a while, were now waking up one after another and starting new cleaning work.

And this time, Lin Feng and the others will directly join the main force, responsible for providing long-range firepower support.

Leader Bai Ye was standing near the entrance of the cave, explaining to Ma Li, another second-level evolver in the Salvation Army, the arrangements and preparations after everyone entered the ruins.

Although Ma Li is tall and sturdy, she is actually a mechanical engineer, not a combat member, and not suitable to follow everyone into the dangerous interior of the ruins.

Before, she was brought underground to break open the closed iron gate, but now that it's purely combat, it's more appropriate to have her stay in the cave on the surface, maintaining order and the refraction of sunlight.

After talking to Ma Li for a while, Bai Ye, who had already seen Lin Feng and the others, walked towards them.

Bai Ye noticed at a glance that the rapid-fire cannon in Lin Feng's hand was much larger than when they first met.

Gun power users can assemble various guns and enhance their power at the same time, which can be called a human-shaped mobile arsenal, and one person can usually release the firepower of a platoon.

Like Lin Feng, who is now at the late stage of the first level and level nineteen, his strength is definitely stronger than ordinary early second-level evolvers.

If the two sides were to engage in a contest, Lin Feng would definitely win from a hundred meters away.

This is the power of gun power users.

It is also the reason why they can thrive in big cities.

Almost no team will refuse to recruit a gun power evolver, although most of them form a wasteland hunting team with themselves as the core.

Just like Lin Feng.

So even in a remote small town, Lin Feng can be on an equal footing with the Oasis Church and reach cooperation.

"It seems that your strength has increased a lot. How is your condition? Have you rested well?"

Bai Ye said with a smile, she had already checked the situation on the second basement level and was very satisfied with Lin Feng's clearing effect.

At this moment, her evaluation of his strength is even higher.

Lin Feng nodded:

"I have to thank you for your generosity, Lord Bai."

"We have already slept, and we have enough energy to deal with the battle on the third basement level."

Bai Ye glanced at the two women behind Lin Feng, both of whom were only at the mid-stage of the first level, but Lin Feng, who was supposed to be protected, was already at level nineteen. She then asked:

"Do you need me to send two more people to be responsible for protecting your safety? That third-level aberrant king is very cunning. I estimate that after seeing your combat power, it will command those second-level aberrants and corrupters to launch a sneak attack on you."

Lin Feng frowned slightly, obviously not expecting this kind of thing. Could it be that the aberrants have also evolved intelligence?

So he asked in reply:

"Has that third-level aberrant developed self-awareness? Or is its level of intelligence very high? Comparable to humans?"

Bai Ye took a deep breath and nodded seriously:

"That's right. We have had two confrontations with it. One was the battle on the second basement level. It led a large group of second-level aberrants and lurked in a certain house to launch a surprise attack on us."

"Fortunately, we had previous experience breaking down doors, and we were prepared along the way, so we didn't suffer much loss and disintegrated their offensive."

"The second confrontation was the previous third basement level. When you were cleaning the second basement level, we were attacked by them at the entrance to the third basement level. This time, the third-level aberrant king became smarter again, trying to find ways to attack the spotlight reflector at the staircase entrance, wanting to destroy the light strike."

"It even used the remains of the aberrant's corpses to pile up at the entrance to prevent the light from entering the third basement level."

"Moreover, those guys have learned to use the remains of ground buildings to block the sunlight. It was the third-level aberrant who taught them, or put them on."

"Their evolution speed is very fast. Before, it was only because they were isolated from the world and had not been in contact with intelligent life. Now, they are rapidly growing in the battle with us."

"Second-level aberrants already have a certain sense of danger, and third-level aberrants even know how to deal with danger. Although it is not clear whether they have self-awareness, we must not continue to treat them as mindless zombies..."

"Otherwise, we will suffer a big loss!"

Lin Feng took a deep breath and nodded seriously:

"Understood, then let's have two people. It just so happens that we can form a four-corner formation and let me stay in the center to support with peace of mind."

Bai Ye nodded and then called over two people.

They were two squad leaders, late-stage first-level evolution, one of whom was the captain who had cooperated in the clearing before.

Lin Feng asked them to follow behind him to ensure the safety of the rear.

With their late-stage evolution strength, they were enough to deal with the sneak attack of second-level aberrants and buy Lin Feng reaction time.

With the personnel arranged, everyone began to enter the underground ruins and engage in a decisive battle with the aberrant tide on the third basement level.

This time, with Lin Feng's joining, the firepower of the Salvation Army directly increased several times.

Soon everyone came to the entrance from the second basement level to the third basement level. Before they even walked in, Lin Feng saw wisps of smoke floating behind the spotlight reflector.

If it weren't still "working hard" to resist the aberrants pouring in from the bottom of the stairs, the second basement level that had just been cleaned would definitely be occupied by the aberrant monster tide again.

More than a dozen main force members of the Salvation Army in front, most of them with late-stage first-level strength, were holding shields and flamethrowers, walking down the stairs.

Lin Feng followed behind them and saw the fire blazing in the corridor. More than a dozen people spread out in a semicircle formation at the entrance of the third basement level, forming a wall of fire.

The members controlling the spotlight reflector behind them also began to adjust the direction, shining into the inner area of the third basement level, illuminating the way for the team.

The raging fire killed one first-level aberrant after another that rushed over.

However, the smooth advance did not last long,

Suddenly, a group of black shadows rushed out from the main road!

A group of humanoid aberrants with various stone slabs tied to their bodies and iron door panels in their hands rushed towards everyone!

Looking at it under the sunlight, it was a group of tall second-level aberrants, intending to break the formation with this.

Lin Feng narrowed his eyes and immediately raised the level nineteen rapid-fire cannon in his hand, aiming at the attacking aberrants.

Twenty or thirty shells in a row poured out, instantly severely damaging a pile of aberrants.

The building materials in their hands could at most resist the light or isolate the burning of the flames for a while, but they had no resistance to the explosive impact damage.

But just as Lin Feng and the others were glad that the aberrant's offensive had been disintegrated...

Several ghostly figures suddenly appeared on the flank of the entire advancing formation!

The speed was so fast, reaching a hundred meters per second!

"Be careful!"

Chen Shanshan sensed it first and reminded aloud.

Shen Yue immediately raised her shield and stood in front of Lin Feng!
