Become a sea squirt larva and eat a brain first

Chapter 1: Beginning as a sea squirt larva

Chen Mu opened his eyes, and as soon as he opened his eyes, he was stunned.

"Water?" Chen Mu found himself surrounded by blue water, and he was actually in the sea.

The blue water was all around.

However, Chen Mu did not feel that he could not breathe, but felt very comfortable.

"What's going on?" Chen Mu looked at his body.

But he found that he had turned into a translucent little thing.

This thing looked like a tadpole, with a big head and a tail.

Chen Mu suddenly noticed that there were several creatures in front of him that looked similar to him.

"Sea squirt larvae..." Chen Mu recognized the identity of the thing in front of him at once.

"Did I become a sea squirt larvae?" Chen Mu was stunned. He wanted to raise his hands, but there were no hands. He wanted to raise his feet, but only the tail was shaking.

What on earth is going on?

Chen Mu remembered that he went to bed, but he woke up and became like this.

Chen Mu couldn't accept it at all.

"No, I don't want to become a sea squirt larvae, I want to become a human, I want to become a human."

Sea squirt larvae are too weak and can become food for other creatures in the sea at any time. Chen Mu doesn't want to die.

"Congratulations on binding the biological evolution system." A mechanical voice sounded.

Hearing this voice, Chen Mu's heart moved: "Who are you?"

"I am the biological evolution system." The mechanical voice had no emotion or tone.

As a modern person, Chen Mu naturally knows about the system. Isn't it the system that only appears in countless novels?

Could it be that I caught up with the trend of time travel and became a sea squirt larvae, and also bound to a system?

But damn, why is it a sea squirt larvae?

Chen Mu was very depressed. He said: "I don't want to be a sea squirt larvae. I want to become a human again. Is it okay?"

"Your original body was killed by an explosion in your sleep. You are now dead and can no longer become a human again." The voice of the system sounded.

Chen Mu was stunned.

"Explosion?"

The system did not answer.

Forget it.

Chen Mu said to the system with the idea of making the best of it: "You said you are a biological evolution system, so what can you do?"

"Everything you eat will be converted into the energy needed for evolution. When the energy is sufficient, you can evolve."

"Evolve?" Chen Mu's heart moved: "Can it evolve into other animals?"

"Yes."

"Can it evolve into humans?"

"I don't know."

I don't know? In other words, it's possible!

Chen Mu suddenly noticed that the sea squirt larvae flying beside him began to attach to the reef and no longer continued to drift with the current.

Chen Mu remembered the habits of sea squirt larvae.

After the sea squirt larvae are born, they will swim in the sea for a few hours, then attach to the bottom of the ship or the reef, and then filter the sea water to eat the nutrients in the sea water for a living.

Chen Mu now needs to eat to get energy, so forget about the sea squirt larvae. It's good enough not to be eaten by others, and it's basically impossible to eat others.

So, Chen Mu chose to follow those sea squirt larvae and attach to the reef.

What to do next?

Chen Mu didn't know what to do, so he could only stay on the reef.

"Getting energy... The required evolutionary energy progress is 0.1%."

The system's voice sounded in his ears.

"What do you mean?" Chen Mu obviously didn't eat anything, but why did the system say that it started to get energy?

Didn't it say that it would start to get energy after eating something?

Chen Mu was a little puzzled, but increasing energy was a good thing, so he didn't think much about it.

But as time went by, Chen Mu found something wrong.

He found that his tail, along with the internal notochord and tail muscles, were quietly shrinking, and the brain in his big head was also disappearing.

Seeing this, Chen Mu immediately understood.

He didn't not eat, but was eating.

What Chen Mu was eating now was actually the notochord, tail and brain in his body.

His body was consuming his brain to get energy!

The evolution of sea squirt larvae into sea squirt adults is called retrograde metamorphosis.

From the perspective of biological evolution, the transformation of sea squirt larvae into sea squirts is a degenerative process.

Many organisms evolved from simple structures to develop sensory nerves and brains.

The larvae of sea squirts, on the other hand, first developed sensory nerves and brains, and then as they grew, they digested the nerves and brains, and their bodies became more simple.

"The required evolutionary energy progress is 65%."

Chen Mu found that his body had turned into a sea squirt, like two tubes inserted into a reef.

One mouth was used to filter seawater and swallow the plankton inside, and the other was for defecation.

Although Chen Mu had no brain and no other organs, no eyes or nose, he could see the surroundings and feel the water flow.

"In other words, I didn't completely turn into a sea squirt. Does the biological evolution system give me vision and perception?"

Forget it, Chen Mu didn't care.

Let's swallow the required energy first.

Chen Mu tried hard to use the mouth that filtered the seawater, sucking water from the seawater and swallowing up the plankton in the seawater.

"There is too little food... We can only rely on the plankton brought by the ocean current." Chen Mu wanted to move, but it was impossible. His body was already attached to the reef and there was no way to move away.

"It's so depressing. It's obviously an animal, but it's like a plant, taking root in the same place."

There was no other way, so he could only continue to eat.

"The energy required for evolution is 66%."

Listening to the system's prompt sound.

Chen Mu suddenly became interested and continued to devour.

He had to quickly accumulate this energy to 100% to see what he would evolve into.

Time passed by little by little.

The energy that the sea squirt could obtain was really too little.

After devouring for half a day, it only added a little energy point.

Chen Mu kept devouring like this, and he didn't know how long it had passed.

Finally...

"The required evolution energy progress is 100%."
