Shadowing --- lifted.

The power that exploded 100% of Gu Feng's whole body faded one after another.

A faint swelling pain appears on the muscles, and there is a feeling of muscle fatigue, but this is not a side effect at all.

After hunting the xenomorphs of the Stage 2 form, Gu Feng was now full of self-confidence.

Although the "Great Zombie" has become more powerful after evolving and mutating into the "Grumpy Tank", its star rarity is too low, even if it is barely upgraded to the 3-star ★ level, it is still not Gu Feng's opponent.

The quality is too far apart!

"The most important thing in evolution is star ★ quality!"

"Although I am only an evolutionary of the first stage form, I have already evolved to a 4-star ★ rarity, and I have also devoured the Corpse King to strengthen my physique."

"Strengthening high-quality genes is like building the foundation for a high-rise building, the stronger the foundation, the thicker the foundation, and the farther you can go in the future......"

Gu Feng had some understanding, but he was not so anxious in his heart, and when he steadily promoted to the 5-star ★ level, no matter how those monsters evolved, they would all be tortured and killed!

Next, it's time for the "harvest"!

Corpse worm, devour!

Gu Feng controlled more than a dozen corpse insects to absorb the corpse of the Grumpy Tank while removing the virus source liquid from it.

The virus source liquid produced by the xenomorphs in the second stage was very dark in color and looked a little different, but Gu Feng still unscrewed a small bottle that he carried with him and put it in.

This vial was already filled with many virus source liquids at this time, most of which were left over from some low-level xenomorphs.

"Hunt a few more, find a safe place, and absorb them together." Gu Feng shook the bottle happily, these are the materials of its evolution.

At the same time, the energy contained in the corpse of this irascible tank is also amazing.

Energy value: 80/500

Energy value: 90/500

Energy value: 100/500

It took more than 10 minutes for the huge body to finish gnawing, absorbing a full 100 points of energy for Gu Feng.

It is worthy of being a second-form xenomorph, and it has never lost such a big size......

Eat dry and wipe clean.

Satisfied, Gu Feng found a secret small room again, and continued to control his tamed little zombie to start the hunt.

In the tide of corpses, a "spy" who is incompatible with other zombie actions is searching.

Like an industrious little bee......

……

……

Time flies.

In the blink of an eye, the day has passed, and it is late at night.

The bright moonlight sprinkled the land, and also sprinkled the rotting and twisted bodies of the zombie monsters, accompanied by the heart-rending roar and roar of the breeze, and those xenomorph monsters would become extremely excited every night.

"Now is the time when xenos are at their most active."

"Going out hunting becomes more dangerous, and the whereabouts of those xenos become erratic."

"Find a secret place and digest the virus source liquid harvested today."

Gu Feng's hunt today is over, and this is a very wise choice.

Night is not the same as day.

During the day, xenos absorb energy in the sunlight and rarely run around.

At night, it is the best time for those terrible monsters to forage and hunt, and it is difficult to pinpoint the location of the scurrying around, and the xenomorphs hidden in the shadows can be life-threatening at any time.

So, the best option at this time is to find a safe and private place to rest, or to evolve!

Moments later......

Gu Feng appeared in a hidden room, a dusty apartment that seemed to be uninhabited before the end of the world.

The door and windows had been sealed with wooden iron plates by Gu Feng, and not a single ray of light could shine through.

And a lot of antiseptic liquid was sprinkled on the door frame and window edge to ensure that the monster would not find him through his sense of smell.

After doing all this, Gu Feng was still not at ease, and hid in the built-in toilet in the room, so that even if the monster sneak attacked, there would be a buffer time.

Energy value: 367/500

Gu Feng glanced at the energy value, then took out a small bottle filled with emerald green liquid.

Virus source liquid!

This small bottle is filled with virus source liquid, and this is all Gu Feng has gained today.

"It's a pity."

"The only thing that can be done is the virus source liquid of that grumpy tank."

"Most of the others are low-level xenomorphs, but there are a lot of them."

A day of hunting was fruitful, but it was impossible for every xenomorph to be as powerful as a raging tank.

The main reason is that the "little zombie" walks too slowly under Gu Feng's control, otherwise it will definitely be able to find more powerful high-level xenomorphs......

So, let's get started!

Gu Feng excitedly unscrewed the lid and swallowed the bottle of virus source liquid.

Evolution begins!!

"Evolution Initiated!"

The cold voice of the system appeared next to Gu Feng's ears, and his body began to absorb these virus source fluids, turning them into material energy for tempering genes.

The scorching energy melted and dispersed in all directions around the body......

This evolution felt very different from the previous ones.

The painful tearing feeling did not arise, and without the feeling of rushing forward, the degree of evolution was slow to grow upward.

Evolution: 60.01

Evolution: 60.02

Although the source fluid of the virus was being consumed, Gu Feng's evolution was so slow that it was devastating.

It wasn't until the time he began to digest the "grumpy tank" that the evolution began to grow, and the familiar tearing pain in the cells came again, but even then it only grew by 3 percent.

Evolution: 63.35

Gu Feng looked at this number with some despair, swallowed so much virus source liquid, and only grew a little bit?

What went wrong?

"System, what's going on with my evolution??" Gu Feng questioned the system.

"Answer the host."

"Your genes are of extremely high quality, and the concentration of these xenomorphs is too low to meet your evolutionary standards."

"You need to use a virus source solution of 4 stars ★ or higher."

The system's words made Gu Feng almost collapse.

Gu Feng is now a Tier 1 (★★★★☆) Evolver.

Moreover, his genes have also been forged and tempered by the Corpse King, and his quality is even better.

Therefore, those low-grade garbage virus source liquids can no longer meet Gu Feng's concentration, the concentration is too low, there are too many impurities, and they cannot meet Gu Feng's evolutionary requirements.

If you want to evolve, you must use a higher quality virus source solution, and you must have a four-star rating or higher......

"Grass!!"

"Four-star or more xenomorphs!"

"Where can I find so many rare xenos above four stars!"

Gu Feng was almost already roaring angrily.

Four-star or more xenomorphs, but rare xenos, it is impossible to be as full of Chinese cabbage as everywhere.

It seems that continuing to evolve is not as easy as Gu Feng thought, and as the quality level increases, his path to becoming stronger will become more and more difficult.

However, just when Gu Feng collapsed and complained, the system answered him very seriously.

"Devouring the training space."
