Wasteland: My items are infinitely upgraded.

Chapter 138 Continuous Upgrade, Level , Battle Level
Carrying the level 18 evolution potion, Lin Feng quickly returned to the camp outside the cave.

This evolution agent, which is close to 300 milliliters, contains rich source materials and comes from the evolution meat of a leader-level rock wildebeest.

If it is divided into two equal parts, it can become two level 17 evolution agents.

It can be given to two mid-stage first-level evolvers to achieve late-stage evolution.

However, only by ensuring the improvement of one's own evolutionary level can the greatest benefits be achieved.

After all, the core combat force of the team is not even Lin Feng himself, but the two guns he upgraded, whose firepower is far stronger than that of the same-level firearms ability users.

Bringing the evolution agent into the chariot, the original level nine purification and extraction filter has been upgraded to level ten:

"Nano-grade source material filter level 10, red quality, brand"

"Basic Attributes: Maximum Aperture 90 nanometers, First-Order Gene Impurity Filtration: 100%; Usage Times: 1; Upgrades consume health points."

"Evaluation: Can perfectly filter out foreign genetic impurities from first-order life essence, obtaining pure essence to achieve immaculate evolution. Second-order life essence has limited filtering capabilities, requiring a maximum pore size of 10 nanometers or less to completely filter out impurities."

Lin Feng narrowed his eyes, and then poured the life source in the evolution agent in his hand into the nano-scale filter to filter out all the rock wildebeest gene fragments inside.

After obtaining a pure eighteen-level life essence, upgrade the filter to save a little life value for refreshing the number of uses.

According to the calculation based on the pore size reduction value of ten nanometers each time, it needs to be upgraded to level eighteen to effectively filter out the impurity fragments in the second-level source material.

After ten hours, when Lin Feng absorbs the second-level life essence of the Rock Wildebeest, he must use an eighteen-level filter to achieve pure evolution.

As for the current eighteenth-level evolution agent, even if it is taken directly, it will not cause much impact on the body, because Lin Feng himself is already a first-level evolver. The first-level evolution cells in his body can deal with foreign cells of the same level on their own and are not contaminated by their genes.

But to be on the safe side, Lin Feng used filtered pure source material every time he evolved. After all, it only took a little health to restore durability and refresh the number of uses, so the cost was almost zero.

After collecting the pure source essence, Lin Feng first ate a piece of level 18 evolved dried meat to recover his condition, then filtered out a large cup of life source essence and drank it directly.

Gulu gulu...

The heat starts from the stomach and spreads to the body.

Lin Feng had a feeling of practicing, as if his Qi was sinking into his Dantian and circulating throughout his body, as if spiritual energy was flowing through his body.

But in reality, it was a large number of level 16 cells in the body that began to divide and proliferate under the stimulation of the level 18 source substance, and evolved to level 17.

The seventeenth-level evolutionary cells at the core fully absorbed the source material and transformed into eighteenth-level cells.

And so on, promoting the evolution of the entire body.

After closing his eyes and resting for a while, Lin Feng successfully completed his transformation and became a powerful evolver of level 18:
"Lin Feng, lv18/19"

「生命值：140，体质：140，精神：139；lv18各属性上限140」

"Super Awakening: Brand Power (Slightly increases the speed of brand equipment enhancement and upgrade)"

"Item upgrade limit increased to level 18!"

"You can consume 5 health points to upgrade the lv17 machine gun, lv17 rapid-fire cannon, and lv11 source filter."

This evolution took less than half an hour.

It is mainly a small-scale evolution within the stage, which does not really bring much improvement. It just makes the foundation of later evolution more solid and lays a good foundation. At the same time, the upper limit of strength breaks through to eight tons, and the overall strength is further improved.

After completing everything, Lin Feng immediately upgraded the level 17 armor-piercing gun and rapid-fire gun around him.

Ten health points were consumed at once, and the peak state that had just evolved was weakened again.

Lin Feng quickly ate half of the level 18 evolution meat.

Each piece of level 18 evolutionary meat is a standard one kilogram, which can restore 20 health points. Half a piece is one kilogram, which is just enough to make up for the 10 points lost during the upgrade.

The reason why he is in such a hurry to upgrade is mainly because he needs to improve his combat effectiveness in the upcoming battle with the mutants. In addition, after Lin Feng's evolution, his camouflage firearms ability must also be improved to be in line with his personality and not be suspected by the Saviors.

Of course, after upgrading to level eleven, the source filter must continue to be upgraded.

The subsequent upgrades were just as Lin Feng had expected. The maximum pore size of the filter element was reduced by ten nanometers each time.

By analogy, when you reach level 18, you will be able to filter the second-order life essence of the patriarch-level rock wildebeest.

The reason why Lin Feng was eager to upgrade the filter was not only because of the need to purify the second-level source essence, but also because of another idea hidden deep in his heart:

That was the evolutionary flesh of a third-order aberration king. Could it also be squeezed out to produce the so-called third-order essence?!
If possible, even if Lin Feng doesn't need it now, he will definitely need it the next time he passes through the Taishan ruins or a wasteland year after the global migration.

After all, judging from Lin Feng's current evolution speed, he will definitely be able to advance to the late second stage within six years. By then, he should also consider advancing to the third stage like Bai Ye and build his own king's city.

If the third-level pollution source in the Taishan ruins can help Lin Feng evolve to the third level, then the value of the source filter in his hand...

That cannot be simply measured by points!

Even millions or tens of millions of points cannot equal the influence of a third-level king.

Even if Lin Feng can't use it now, as long as he can obtain even a little bit of the third-level source essence, it will become one of his biggest trump cards in the future.

Once you're fully grown, you can take it to the guild to trade and earn at least several million points.

After all, a piece of second-stage, early-stage, level 20 life essence can be sold for 200,000 points, and a pure one costs a million points. Then, wouldn’t a pure third-stage life essence be sold for tens of millions?
To be precise, its value can no longer be simply measured by points currency, because its pure attributes give it more additional value.

For example, the protection of a third-level king, or winning over some large forces to support them.

Even the first- and second-order pure essences in Bai Ye's hands can be attached with various conditions, gaining favors beyond the price itself...

Others will naturally follow suit.

Thinking of this, Lin Feng swallowed the dried meat in his mouth and accelerated the upgrade of the nano-level source filter.

Combined with the additional attributes of the brand, the upgrade speed of the filter is faster than that of the armor-piercing cannon and rapid-fire cannon, and it only takes about ten minutes to upgrade one level on average.

After waiting for more than an hour, the filter, which had become level 16, began to slow down its upgrade speed. Its main grade gradually approached Lin Feng's evolution level, and it was no longer as fast.

At this time, Lin Feng had already eaten three large pieces of dried meat to restore the health points consumed by the upgrade.

The repeated consumption and recovery also affected his mental state, so he put away several pieces of branded equipment, spread out the cushions in the back row, and planned to take a short rest.

It’s not even half past one now, and there’s still an hour and a half until three o’clock, which is just the right time to catch up on some sleep.

Although the biological clocks of all humans are disrupted in the wasteland under the oasis, it will have a great impact on the body in the long run.

It is mainly intermittent sleep, which keeps the nerves tense for a long time and greatly affects one's mental state.

Over time, people will suffer from nervous breakdown.

This is also the reason why the evolvers who come from the wild people have a weaker foundation than those cultivated by other family forces.

Fortunately, Lin Feng, who had just woken up, did not have such an experience. After visiting the Oasis Shangmin District, he also realized the importance of a normal schedule.

The church provided such good living conditions for the Shangmin in order to cultivate their spiritual strength. It even built a garden and provided a large number of musical instruments to meet their spiritual and cultural needs.

Extend the Moonlight Ritual observation time as long as possible.

Although Lin Feng didn't know what the spiritual power was used for, as one of the three basic attributes, it must be very important.

Taking the currently known evolutionary principles as an example, the second-level evolvers have solved the problem of physical longevity. They have unlocked the genetic shackles of cell aging and can achieve physical immortality, just like the famous cancer cell "HeLa".

But what limits the immortality of second-level evolvers is the loss and decline of spiritual consciousness.

Consciousness condensed by memory will disappear.

Even humans with the most developed brains will lose most of their memory as they grow and age, a case in point being Alzheimer's disease.

However, the longest-lasting way to preserve information in the world is the most primitive stone carvings, which can last for tens or even millions of years.

Lin Feng once saw on the top of Laoshan Mountain a large number of time records and warnings to future generations left by the first survivors six thousand years ago.

The more advanced the recording method, the shorter the preservation time and the lower the effectiveness.

This is equally fatal to living things. As memory loss accelerates in the later stages, they are actually no different from the living dead.

Therefore, most of the long-lived life forms in nature are either sluggish and dull in their movements, or have not evolved rich neurons at all, and are just low-level life forms without brains.

For example, the 500-year-old Greenland shark, or fungal aggregates, and the so-called "immortal" immortal jellyfish.

This low-level intestinal animal has only a few reflex nerves in its body and does not even have self-awareness. It is only slightly more advanced than a sponge. Calling it a ball of moving meat is a bit of an exaggeration.

To truly achieve immortality, we must alleviate the attenuation and aging of the brain, an organ that carries consciousness and has high energy density, as the entropy increases over time.

As for the solution, Father Su An had already hinted to Lin Feng that it was the evolutionary path of a third-order king, which was to directly integrate his own memories and information into his genes.

Use genes to carry one's own consciousness.

This can also explain why there is genetic radiation around the third-level king, and the missed blood tissue will cause serious genetic pollution, forming a life forbidden zone.

As for how to integrate his own consciousness and memory into the genetic body, although Lin Feng currently has no idea, he can basically confirm that it is related to the spirit among the three basic attributes.

So now pay attention to maintaining a good mental state. It will only benefit your future evolution and not harm it.

What's more, the third-order deformed being that they will fight later, although it is just a contaminated third-order king, and its strength is at most at the late second-order, but it is still called the third-order, and it is by no means as easy as the cleaning work on the upper three levels, which only requires moving a finger and pulling a trigger.

We still need to stay alert and be prepared.

Lin Feng fell into a deep sleep. After sleeping for more than an hour, he was awakened by Chen Shanshan who came in.

She went to bed early and went to the dormitory car as soon as she came back at twelve o'clock.

He woke up after sleeping for more than two hours. Seeing that there were only twenty minutes left until three o'clock, he hurried to wake up Lin Feng.

The moment he opened his eyes, a series of reminders popped up in the corner of his eyes. The two branded guns had been upgraded to level eighteen, and the source filter had also been successfully upgraded to level seventeen.

Lin Feng got up and asked Chen Shanshan to clean up first, while he checked the properties of the upgraded equipment:
"Armor-piercing cannon level 18, red quality, branded"

"Basic Attributes: Damage 150, Effective Range 2km, Damage Coverage 12m, Remaining Tungsten Core Armor Piercing 350; Upgraded to Host Level Cap."

「额外属性：子弹回复1/1h；空间弹匣350枚；范围杀伤(覆盖半径12米，中心2米伤害160)；火力覆盖(一秒六发持续五秒)；穿甲炮弹(穿甲能力提升100%，伤害+10)」

「Note: You can switch back to lv9 boutique AK freely」

"Note: The current basic damage has reached the upper limit of the second-level red quality. The next upgrade will continue to enhance the bullet damage, and the benefits will be reduced." After this upgrade, the basic damage was successfully increased to 150 points, which is equivalent to the upper limit of health at level 19. The shell damage cannot be further enhanced in the future.

However, the damage is sufficient. With the additional ten points of armor-piercing shells, the current maximum damage has reached 160. It is invincible and unstoppable below the second level.

When Lin Feng evolves to level 19, he can choose to increase the recovery speed of the shells or expand the ammunition capacity.

However, Lin Feng prefers the former.

If one shell can be restored per minute, there will be fifty more spare shells than the expansion capacity, which is much more useful.

Because it is rare to shoot 300 missiles in one go, but recovery is too slow.

One bomb per hour, only twenty-four bombs per day, not enough for Lin Feng to cover fire for five seconds. After firing a few rounds, he would have to wait two or three days before he could recover.

If one shell is replenished per minute, that means sixty shells per hour, and the full replenishment can be achieved in six hours.

After checking the extreme damage of the eighteenth-level armor-piercing cannon, Lin Feng immediately checked another rapid-fire cannon of the same level:
"Rapid-fire cannon level 18, red quality, branded"

"Basic Attributes: Damage 110, Effective Range 2km, Damage Coverage 6m, Remaining Explosives 3500; Upgraded to Host Level Cap."

「额外属性：子弹回复1/1s；空间弹匣3500枚；范围杀伤(覆盖半径6米，中心1米伤害110)；极速追击(自动模式每秒十发)」

「Note: You can switch back to level 9 precision pistol freely」

Unlike the armor-piercing cannon, which had an increase of fifty rounds of spare ammunition, the rapid-fire cannon directly increased by five hundred rounds after being strengthened by Lin Feng's imprint.

The increase from one upgrade is more than the ammunition of the entire armor-piercing gun.

With such a huge amount of ammunition, even if the damage is only over 100, it is enough to make up for the lack of damage.

What Lin Feng ultimately wanted was a full 4,000 spare rounds of ammunition to deal with the next wave of distorted monsters on the fourth and fifth floors of the ruins.

There were tens of thousands of them, overwhelming them, and they didn't have enough ammunition. If anything went wrong, like this mutant riot, Lin Feng had to first ensure that he could safely evacuate the ruins and fight his way back to the surface.

Therefore, the number of bullets in the space magazine becomes a crucial attribute.

Lin Feng stared at the rapid-fire cannon in his hand, and suddenly realized that the so-called space magazine, the expansion space inside, and the spatial ability that Ding Yi had analyzed before, actually had the same principle.

The source of the space magazine is the vacuum bubble area created when the granular gunpowder in the bullet body burns rapidly after the bullet is fired, pushing the bullet forward.

Although this area will soon be filled with the explosive gas of gunpowder, there is indeed a vacuum area at the tail when the pressure generated by the explosion pushes the bullet forward.

This can be clearly seen when a bullet is fired underwater, where a vacuum cavity is formed in the low-pressure area at the tail of the bullet.

Lin Feng narrowed his eyes slightly. If the gun created a vacuum area during the firing of the bullet, thus upgrading the original magazine to a space magazine...

So as long as a vacuum area is designed on other items and equipment, can an additional space storage attribute be upgraded?

Thinking of this, Lin Feng slowly raised his head and looked at the level 17 Rock Horse Chariot around him.

A bold plan slowly emerged in my mind.

But Lin Feng thought again, it doesn’t seem to be very useful to create an expanded storage space on a tram with a low load capacity. After all, if more things are stuffed in, the weight of the storage box will increase.

Because what is lacking now is more abundant motivation.

Rather than load space.

Perhaps in the future, when a better power system is found that can travel at a speed of 100 kilometers per hour, the extra storage space on the tank will have practical significance when it is put to use.

For example, on the Green War battleship, an ultra-large capacity expansion space was upgraded to store fresh water resources, which is both safe and convenient.

Lin Feng's occasional flash of inspiration was rejected. After checking the two guns, he consumed another five health points to upgrade the level 17 filter...

After finishing everything, Lin Feng immediately stood up and walked out of the car and put on the sealed armor.

At this time, Chen Shanshan was ready. Shen Yue in the car opposite was yawning, holding up her shield, and walking towards the two of them.

At 2:50, the three of them continued their journey and headed towards the cave entrance at the foot of the mountain.

After arriving at the cave, the four Salvation Army members who had followed the three to clear out the underground first floor continued to follow and were now waiting at the cave entrance.

The main reason is that the flamethrowers in their hands are only suitable for close combat burning. Beyond twenty or thirty meters, the effect will be greatly reduced. Therefore, in the dark space below the negative third floor, they are very suitable for dealing with sudden attacks from deformed monsters.

But during the clearing operation, the terrified deformed creatures ran faster than each other, and would run away as soon as they heard a sound when the door was opened.

Stay away from humans who come out of the light.

At this time, Lin Feng needs the guns and cannons in his hands to provide long-range firepower strikes to eliminate all the remaining deformed creatures.

Only then can the Salvation Army members focus on moving machine tools and industrial lines with peace of mind.

Otherwise, with more than 80% of the personnel engaged in transportation, the remaining 20% ​​of the guards would have difficulty in dealing with even one or two hundred evolved mutants.

The most important thing is to prevent them from attacking and causing damage to machine tools and production lines.

Protecting the equipment is more important than killing the aberrations.

This is also why Lin Feng is needed to clear out most of the deformed creatures in the upper three layers.

When the sunlight reflected by the concentrator is aimed at the entrance to the next level, there is no light on both sides of the main road. Even though the deformed monsters have been driven away now, once they launch an attack, it will cause immeasurable losses.

The significance of military production is that it is the ruling foundation of first-class forces, and is listed as one of the three major foundations along with the food and evolution provided by the wildebeest industry.

They represent weapons, food, and the people who make up the forces.

Therefore, military equipment cannot be lost.

Of course, Bai Ye arranged Lin Feng to clear out the deformed creatures in order to check and evaluate his strength and see if he was qualified to receive advance investment from the Salvation Army to ensure the smooth shipment of the equipment.

Led by the Salvation Army team leader, Lin Feng and the other two walked through the clean and bright basement floor and entered the slightly dim basement floor.

Through the refraction of the spotlight at the stairwell, the brightness of the space on the second underground floor is enough to clearly see objects three to four hundred meters away, which is equivalent to the evening when the sun sets.

The residual temperature of the beam above my head also dropped from 500 to 600 degrees Celsius on the first floor below ground to 200 to 300 degrees Celsius.

Lin Feng felt the changes in the environment and frowned slightly.

The outside sunlight decays so rapidly that by the time we reach the third floor below ground, the effect will be less than Baidu's.

It also needs to penetrate the humid mist in the air, and the brightness and temperature of the light beam will attenuate again.

It seems that the third floor below zero is its limit.

Even the decisive battle originally scheduled for the negative fourth floor will be moved forward to the negative third floor.

Lin Feng saw from afar that the main force of the Salvation Army was currently gathering at the entrance from the second to the third basement floor, setting up the third concentrator.

"Let's go. Our mission leader has explained that there are quite a lot of remaining aberrations on the negative second floor this time, covering a full five square kilometers, in the dilapidated hibernation pod areas on both sides."

"There are no fewer than three hundred of them, and there are more than thirty of them that are second-order aberrations."

"Our mission is to eliminate as many of them as possible, at least two hundred of them, especially the second-level aberrations. The more we kill, the better."

After walking down the stairs and reaching the basement level, the leader of the Salvation Army team spoke to everyone and continued:

"The mission time is nine hours, which means before noon. Time is still a bit tight, so let's get started quickly, starting from the left!"

After saying that, he began to walk towards the residential area on the left with the three team members behind him, as well as Lin Feng and the other two.

In addition to the flamethrower, the Salvation Army also has a bright searchlight that can illuminate an area of ​​100 meters, which is very suitable for building inspections and improving efficiency.

As for Lin Feng, he only needed to shoot directly as soon as he heard any movement, in order to seriously injure the deformed person.

With the cooperation of several people, the speed of the sweep became faster and faster.

During the period, when it was approaching a corner, it encountered a counterattack from four or five second-level mutants, but under the continuous firing of the rapid-fire cannon and the huge damage of the armor-piercing cannon, they were all seriously injured before they rushed to fifty meters in front of Lin Feng.

Especially the level 18 armor-piercing cannon, which has a killing range of 12 meters and a shell damage of 160, which can effectively kill deformed monsters with flesh and blood bodies.

If it was a second-level evolver wearing armor, it would not be so easy to be seriously injured. At least the opponent's torso would have to be hit accurately.

The real killing power of the armor-piercing cannon has been seriously exceeded after Lin Feng's several damage enhancements. It is specially prepared to kill the leader-level and patriarch-level rock horn beetles.

As the wild beasts with the strongest defensive attributes, they are covered with nearly half a meter thick ceramic steel rock armor, which is as hard as titanium alloy. Even the eighteen-level armor-piercing cannons are not enough to damage them.

To upgrade heavy artillery with this standard, in other words, apart from the Li family's Rock Horse Armor, there is no ordinary evolved life that can withstand armor-piercing artillery.

As Lin Feng killed his way forward, he circled the underground second floor three or four times, from three in the morning until eleven in the morning, and finally killed more than two hundred and fifty deformed monsters!

Among them, there are more than 40 second-order aberrations, which have already achieved the set goals.

The remaining aberrations have been playing hide-and-seek with everyone, so there is little point in continuing to chase them.

The last group of seven people rested at the entrance of the negative third floor, and the team leader of the late first stage went down to report on the completion of the mission.

Soon, Bai Ye followed him back to the basement level and walked towards Lin Feng who was leaning against the wall.

"Thank you for your hard work. Go find Mali to get the essence. Rest for a while and remember to replenish your nutrition and recover your condition."

"Due to the attenuation of light, most of the negative third floor is still shrouded in darkness. Thousands of aberrations remain, including a third-order aberration king..."

"At three o'clock in the afternoon, we plan to try to see if we can keep it completely."

"Your fire support will be crucial!"

After saying that, Bai Ye reached out and patted Lin Feng on the shoulder:

"Don't worry, regardless of whether we kill the third-order aberration or not, as long as we clear the negative third floor, I will definitely give you your share of the Patriarch-level Rockhorn Beetle Life Essence."

"As for now, go and get some rest!"

Lin Feng nodded and stood up.

Follow the team leader and his four companions back to the surface.

Once again, he obtained the nineteenth-level life essence from Ma Li. This would be before he could advance to the second level...

The last evolution!
