Natural selection of the fittest to survive, in order to survive, living beings have been constantly adapting to the environment, although the evolution of each creature from birth to death is negligible, but the evolution of genes is carried on with reproduction, so that the offspring are more adapted to the environment. There are also many organisms that can evolve directly in a limited life, from crawling larvae to various forms of adults, and caterpillars are a typical example of this.

Silking, cocooning, and butterfly transformation are the steps in which caterpillars evolve into butterflies. Of course, this is Gu Zheng's understanding of the evolution of caterpillars. Gu Zheng's biological knowledge is quite lacking, he only knows that this creature can evolve like this, and it is generally called so, and he doesn't know the name of the caterpillar in the book, so Gu Zheng only has a general understanding of the caterpillar. In Gu Zheng's mind, if the caterpillar wants to evolve into a butterfly, it needs to spin silk, and then hold itself in a cocoon for a long time before it can evolve.

And the caterpillar in front of Gu Zheng and the others was obviously not an ordinary creature, and when everyone was thinking about how to stuff such a big piece of caterpillar into their mouths, this caterpillar suddenly stood up with its tail end to support its body, and then opened its mouth and began to spit silk. The caterpillar's mouth was like a watering can, and the silk thread brush kept flying out, and the soft silk thread immediately solidified when it met the air, but in just a few seconds, the caterpillar wrapped itself tightly with the silk thread.

Gu Zheng stretched out his hand and poked the cocoon, suddenly raised his head and said, "You see that this thing is also made of poison, otherwise let's try to break this cocoon, maybe we can detoxify ......"

Wu Ju saw Gu Zheng's movements, and immediately stood up with a pale face and roared, "Release your claws, don't touch it!"

The hoarse voice and hoarse tone, if it weren't for the insect cocoon here, Gu Zheng would have wondered if it had moved Wu Ju's wife...... After taking a few deep breaths, Wu Ju suppressed the anger in his heart and said, "This insect obviously has the ability to devour poisons, but we don't know if it has the effect of detoxification. Right now, this bug has formed a cocoon, and there should be no way to use it in a short time, and I ...... now."

Click, click!

Before Wu Ju's words were finished, there was a crack in the insect cocoon that had just formed, if it weren't for Gu Zheng only poking it lightly twice, everyone even wondered if Gu Zheng had used too much force and directly punctured the insect cocoon. However, after all, this bug carried the lives of several people, and the current change immediately attracted everyone's attention. Under the gaze of everyone, in just a dozen seconds, this butterfly crawled out of the broken cocoon.

The butterfly's torso is only the length and thickness of a finger, but the wings behind it are the size of a palm on each side. It is covered in emerald green, with only white markings in the center of its wings, and when it spreads its wings and flies, it looks like a face floating in the air. The combination of a green body, white patterns, and a human-like appearance makes this butterfly look extremely strange. The butterfly that had just broken out of the cocoon was not afraid of people, but kept flying around Gu Zheng's side, looking like it was quite happy, tentatively stretched out its palm, and the butterfly immediately landed firmly in Gu Zheng's palm. It looked like a pale person, smiling at Gu Zheng. Gu Zheng just wanted to try to see if this butterfly could wake up the rest of the people, but the butterfly suddenly opened its mouth, and a slender mouthpiece suddenly pierced into Gu Zheng's palm!

This butterfly's mouth is huge, and when it is opened, it occupies two-thirds of its head, and the mouth of this butterfly is full of dense sharp teeth, which circle and circle to the depths of the mouth, which looks quite disgusting, and the mouthparts that pierced into Gu Zheng's palm are like the tongue of this butterfly. Seeing this butterfly attacking Gu Zheng, Wu Ju and the others immediately stood up in a hurry, and Gu Zheng immediately waved his hand to signal that he was fine. Of course, Wu Ju and the others stood up probably just worried that things would change, after all, this butterfly was carrying several lives at this time.

The butterfly stood in Gu Zheng's palm, trembling its body with great difficulty, and in the thin mouthparts, you could see that green liquid was injected into Gu Zheng's body little by little. The whole injection process was extremely slow, and Gu Zheng could also feel that the attack power of this butterfly's mouthparts was extremely weak and fragile, as long as he used a little force, he could break this mouthparts, but Gu Zheng did not do this.

The origin of this butterfly Gu Zheng knows well, it is the work of the inexplicable king in the body, and now the king and Gu Zheng are one, no matter for any reason, the other party has no reason to kill Gu Zheng. Even if the other party wanted to kill Gu Zheng with some kind of poison, and then seize Gu Zheng's body, it would not be enough to use such a low-end attack method. Therefore, Gu Zheng is willing to believe that this butterfly is doing this completely for Gu Zheng's good.

Sure enough, although the green liquid was injected into his body, Gu Zheng could feel a force slowly flowing through his body. It was an indescribable energy, he could feel the heat flow circulating in his body, but he couldn't control it, every time this heat flow traveled around his body, Gu Zheng could feel that he was a little stronger. Strength, Vision...... This energy can be absorbed and then continuously strengthened in the body, which feels exactly the same as strengthening the body in the ark!

At this time, Gu Zheng squinted his eyes slightly, his body trembled slightly, and he looked as if he was enduring something. Wu Ju and the others saw it really, and they didn't dare to make any moves for a while, and it seemed that they still had a little respect. It is estimated that these people feel that Gu Zheng is sacrificing himself for others, and suffering along the butterfly in order to save people, but in fact, Gu Zheng has already laughed crazy in his heart, and the body can't help but tremble, in fact, because he is too happy and excited.

Strengthening the body in the ark, each point of attribute value is extremely expensive, and it can not be strengthened after reaching a certain level, in addition, the ark can only strengthen the physical fitness, and attributes such as energy cannot be strengthened at all. But this butterfly is different, Gu Zheng can feel that this kind of enhancement is all-round, every cell is being strengthened, that warm current is energy, although I don't know what the attribute is, and it can't be used because there is no exercise, but it can be stored in the body! What kind of butterfly is this, it is completely a mobile body strengthening machine, and it doesn't cost money! The value of this butterfly can't be measured by life span at all, it's completely priceless!

Gu Zheng clearly remembered that the caterpillars that were exactly the same as this butterfly produced were extremely easy, almost to the point of being inexhaustible. The only thing that doesn't matter is how to trigger the appearance of bugs. As long as you can find a way to trigger the king, you can continue to produce this caterpillar!
