The evolution of Zerg

As for the inability to reproduce in large numbers, one is due to body size and the other is due to nutrients.

The sea snake swam to a small island at an extremely fast speed. This island was an uninhabited island, which just met Zhang Fan's development needs.

The bacteria's bodies began to mutate, their surfaces were covered with a thick film, and then they slowly crawled onto the island.

The monitor lizard on the island discovered this group of uninvited guests and crawled over while spitting out snake messages.

They opened their mouths and bit down on the outer shell of the bacteria. However, what they didn't expect was that the bacteria were not bitten into pieces, causing their teeth to hurt.

Zhang Fan felt that he had been bitten. He couldn't let it go. The bacteria chased the group of lizards with their flagella waving.

Looking at the increasing number of bacteria, the lizards finally felt scared and began to run away.

However, one lizard was left behind, a truly terrifying group of bacteria.

Zhang Fan looked at the little lizard and thought to himself, "Well, I have a good idea. I don't know if it will work."

So, the bacteria dragged the lizard down into the ocean, the sea snake released the modified cells, and the lizard was successfully modified.

Then, Zhang Fan discovered that this was a female lizard that was about to give birth. After thinking about it, Zhang Fan decided to occupy a lizard egg first.

A few days later, the female lizard successfully gave birth to lizard eggs, but one of them was too big and eventually suffocated the female lizard to death.

And this egg was a lizard egg that had been modified by Zhang Fan, and it was incubating at a high speed.

When all the nutrient solution in the eggs is absorbed, the little lizards begin to break out of their shells.

This kind of lizard is called an iguana. It is a lizard that can walk upright. It has sharp scales on its back and very sharp claws.

Zhang Fan has transformed into this little lizard. He swallowed all the eggshells into his stomach, and he couldn't let go of the remaining egg white inside.

After drinking and eating, Zhang Fan slowly walked out of the lair, the dazzling sunlight stinging his eyes.

The tail behind him swung involuntarily. Looking at the sharp claws, Zhang Fan decided to hunt first.

Through the investigation of the bacteria, Zhang Fan already knew that turtle eggs were hidden somewhere, so he ran towards the coast.

After lifting a large stone, densely packed white turtle eggs were revealed inside. Zhang Fan rolled up an egg with his tail, smashed it and swallowed the nutrients inside, which was a bit like seafood bone soup.

When Zhang Fan was eating with gusto, the female turtle came back. She looked at Zhang Fan devouring her children and made a turtle-like hissing sound.

Zhang Fan continued to eat the turtle eggs unmoved. Now the female turtle couldn't bear it anymore and quickly crawled towards Zhang Fan.

"The opponent is too big and cannot be defeated. I will come back to you when I grow up in two days." After saying that, Zhang Fan ran away, and his speed was not slow.

After returning to the lair, Zhang Fan needed to digest the supplemented nutrients, so he slowly closed his eyes and fell into a deep sleep.

When he opened his eyes again, he felt his body was a little crowded. He touched the surrounding rock walls and found that the nest was a little small.

There is no way, the iguana has grown in size, and the nest can no longer accommodate creatures larger than half a meter.

What are the bacteria doing at this time? After they have scouted out the location of the iguanas, they start heading to all corners of the world to help the iguanas open up a great shipping route.

"Gululu." Zhang Fan was a little hungry. He had to continue eating. An iguana with sharp claws and fangs could not be a herbivore.

So, Zhang Fan started looking through the nests of insects and found a group of big and fat white insects in a rotten tree.

After stuffing these white worms into your mouth, it feels like you have gone back to time hundreds of years ago.

White worms are very nutritious, about six times as much as beef and twice as much as sea turtle eggs. After Zhang Fan finished eating the whole white worm in the rotten wood, he patted his round belly and burped.

"We should find a place to stay for the time being." Zhang Fan looked around, but couldn't find a suitable place, so he decided to leave it for now, Lieutenant General Kuchiki.

One night passed, and the iguana grew in size again. When Zhang Fan woke up, the rotten wood had been completely burst, and its skin had also been replaced.

The current body length has reached 1.5 meters, and it is about 1 meter when standing up. It looks majestic and domineering.

Finally, Zhang Fan was going to find a turtle to practice his skills with, and fight with him first. If he could kill him, he would have food for tonight.

Arriving at the beach again, Zhang Fan was lucky. These days happened to be the spawning period of sea turtles.

He ran up to a turtle and punched the turtle in the head. The turtle was a little confused and looked at Zhang Fan blankly, not understanding why he hit himself.

Zhang Fan pursed his lips and realized that the heavy punch did not knock the turtle unconscious. When he was about to punch him, the turtle had already retracted its head into its shell.

Zhang Fan missed the target with one punch, but Zhang Fan was not discouraged and began to hammer the turtle's shell. However, the current iguana's strength was too weak. If it were a springtail, it would definitely be able to penetrate it with one blow. Of course, if the iguana jumped, If the insect really comes, it is estimated that one blow can penetrate the entire planet.

After beating the turtle for a long time, there was no movement. Zhang Fan shook his head and said, "Forget it, I'll spare you for now. I'll take care of you when I get older!"

Abandoning the turtle, Zhang Fan returned to the forest again.

After seeing no movement for a long time, the turtle began to poke its head out and returned to the sea in a panic.

In the forest, Zhang Fan began to bully some larger insects and some small animals.

He didn't expect that there were rats in this island forest. It wasn't until he saw rats swimming that Zhang Fan knew the origin of these rats.

These agile little guys are difficult to catch. They are very vigilant and very smart. Sometimes they can fool Zhang Fan around.

However, no matter how smart these guys are, they are just lower-level animals and cannot be compared with higher-level creatures with intelligence.

After leading Zhang Fan to dig some traps, they successfully captured these rats. They wanted to fight back, but they couldn't break Zhang Fan's scales.

After eating rats and worms, Zhang Fan lived a carefree life like this. He would not lay a germ blanket here. If he did, he would lose a lot of fun.

The iguana has grown to 3 meters in size and stands about 2 meters tall, just like the Igwanna tribe.

Zhang Fan once again sought revenge on the turtle. This time he knocked it down easily with one punch. Even if it was hiding in the turtle shell, Zhang Fan could break it into pieces.

All the creatures on this island were eaten by Zhang Fan, and they became even larger. Some trees were crushed underground by Zhang Fan. The iguana's body length has reached 6 meters, and its height has reached 4 meters.
