Judging from Qin Gu's perception, this one-dimensional world is neither ocean nor space, but a chaotic world full of various forms of life forms and all kinds of matter.

Everything here is still floating if there is no external force, so no matter what kind of life form can move, it can swim freely, as long as it is not eaten by a predator.

Qingu shrunk up as much as he could, hiding behind a larger meteorite, trying to wait for the other party to swim over. After all, there is a difference in the size of each other, and the other party is full of stingers, so even if they sneak attack, they have no chance of winning.

But the other party sensed the breath of the prey, and opened his mouth to bite the meteorite where Qin Gu was hiding.

With the help of the blockage and power of the meteorite, the two "feet" kicked suddenly, and the body retreated quickly to the back, and the largemouth bit the meteorite in one bite, but there was a stinging pain in the mouth.

Qin Gu took the spikes he had prepared earlier with black particles and launched them when the other party was biting.

The largemouth fish was caught off guard by the attack, and suddenly became more violent, only to see its body bulge violently, and the spikes on its back suddenly shot towards Qingu.

The two were not far apart, and the impact speed of the largemouth was too fast, Qin Gu avoided a few poisonous needles, and there were still two poisonous stingers that stabbed one tentacle.

Suddenly, Qin Gu felt that her connection with the tentacle had been severed, and then, the cells around the poison needle became inactive, and she moved slightly, and she actually broke off from the poison needle.

Hey, it's so toxic!

Qin Gu subconsciously placed more special cells on the severed tentacles, and then frantically waved the remaining tentacles to escape.

The largemouth fish rushed over with a swing of its tail, swallowed the severed tentacle in one gulp, and then continued to pursue towards Qingu.

After all, in the nearby area, the size of Qiangu was barely enough for the other party to fight a tooth sacrifice.

Qin Gu was depressed in his heart, could it be that the tried-and-true black substance was useless to this largemouth?

In that case, she had no choice. After all, the size, the speed is there.

Deal......

Qin Gu had already made the final plan, placing his consciousness cells behind a meteorite...... With just a little bit, she can make a comeback!

Qin Gu tried his best to escape, but was finally bitten by the largemouth.

Qingu frantically releases special cells in his body, as well as digestive juices stored in the stomach pouch. The remaining tentacles instinctively wrapped around the opponent's body, and as a result, they were stabbed by the stinger, and before the black substance could take effect, the tentacles almost fell off.

The largemouth frantically tore at Qin Gu's body, but a window appeared in the mouth, and the ulceration became deeper and wider, and finally gradually lost its strength, and then ......

Qin Gu now has only one head left in his body, but fortunately, the central digestive organ inside has not been destroyed, and it can decompose all kinds of energy and substances faster.

Qingu decomposes sacs and slime to separate the spikes from the largemouth's venom, and then smows the battlefield in a frenzy - if there is another largemouth now, she will be completely finished.

This battle allowed her to not only "recover" the limbs that had been lost, but also digest all the largemouths. Harvest a huge amount of energy and matter.

She faces a new evolutionary problem: the octopus is agile and easy to hunt, but against a stronger opponent, if she doesn't have the black substance card, she will still finish playing. So she can't turn into an octopus this time.

Largemouths are great, but they're not perfect. The most powerful weapons are spikes, toxins, and fangs, but these are also very limited when attacking...... If you meet someone like yourself again, who is tricked by the mouth, won't you also wait for death?!

Qin Gu thought about it, or ...... Evolving into a humanoid?

Qin Gu had thought about the human form before, but there was not enough material at that time, and her understanding of the living body could not complete a complete human body structure.

Now, these substances should work.

There has just been a fierce battle between the two "giants" here, so there shouldn't be any other predators coming for now.

Just in case, Qingu pushed the surrounding meteorites together to enclose a space.

Then, Qingu began to assemble these substances one by one...... Start by building a model of a person and then supplement it little by little.

First bones, muscles, skin.

The most important thing is the arm, and the most powerful thing about people is that they can use tools and are flexible.

Qingu assembles the parts that he thinks are most important, his torso is balanced and large foods are digested and absorbed, his feet are mainly used to move his body, and his hands are used to control tools......

By the way, what about the head?

Qin Gu finally found that the human figure he assembled did not have a head.

Looking at the materials that have been used, in fact, the head is the control and the main senses. And Qingu can now control all cells and perceive everything in the outside world through consciousness, so it doesn't matter if he has a head or not.

The venom of the largemouth fish is very domineering and very corrosive, and if you have to make an analogy, it feels like it has a strong acid that she once recognized in the three-dimensional small world.

Qin Gu tried many ways to collect it for his own use, and found that this thing could corrode even ordinary stones.

However, the extremely pure crystal sand can isolate it.

The spikes on the largemouth are made of crystal sand, translucent, very sharp, hard, hollow like a needle, which can store venom.

It's not enough to be able to store venom, after all, this thing is so domineering, if you don't really master the method, it's a double-edged sword to use yourself, and you don't feel at ease.

Qingu tried to release the black substance in the special cells, and found that the two fused into a very viscous mucus, and the ductility was also very good.

A crazy idea arose in Qingu's consciousness: a cell membrane controlled by consciousness was split from the body to cover this mucus, which could control its expansion and contraction, and it could be expanded to become a huge handkerchief, which would be a pocket when it was closed, and then release venom or special cells......

The mind controls the cells of the body to function, and the epidermal cells work at the same time, splitting into a thin film made up of two layers of cells, which then detach from the surface of the body and gently wrap around the mutated mucus.

Three small sacs are divided into a row, which can be thrown as weapons when needed.

The first thing Qingu did when he had a body was to use his hands to start making tools for himself. In fact, she also had a body similar to lobsters, starfish, and pirates before, and she could also make some small trap tools or something, but she always felt that it was still not as easy to use as a human body, and it seemed that the human body evolved through hundreds of thousands of times is indeed the survival of the fittest.

Qin Gu hadn't converted all of her venom into slime, and there was only a small part left, which she had only found on this largemouth so far.
