Chu Yi looked at his watch and decided to see how long he could stay in the water.

Breathing fresh oxygen, Chu Yi dived into the deep of Renyu Bay.

"It should be more than 20 meters here. How can I dive so deep?" Chu Yi stepped on coral coke and didn't dare to dive deep.

Because he didn't know how long he would be able to dive in the water. If he was too deep to return, wouldn't he have lost his life in the deep sea?

Chu Yi doesn't do things that are uncertain.

"It's been twelve minutes, and it feels good." Chu Yi went upstream a little and felt that the oxygen seemed to be less and less, and his head was still a little dizzy. Therefore, I dare not stay any longer.

"Fifteen minutes. I can't believe I stayed in the water for fifteen minutes without diving equipment. After you improve your mental strength through the Dragon formula, can you stay longer? " Chu Yi surfaced and talked to himself excitedly.

After resting on the water for a while, Chu Yi plunges into the water again.

This time, he had more confidence. Looking at the time, he kept diving deep to see if he would not be affected by the water pressure.

"This should be the limit that I can dive, and I don't know how many meters." Feel the pressure suddenly increased, Chu Yi quickly upstream.

After all, he didn't take any measuring tools with him. He didn't know how deep he had just dived.

But he estimated that it should be more than 50 meters.

It's impossible for human beings to dive so deep.

After returning to the sea, Chu Yi felt tired and didn't stay in the water. After saying goodbye to Xiao Hui, he left the sea.

Chu Yi did not go home, but walked towards the direction of the shallow dragon beach.

Into the shallow dragon beach, a stink on the face, almost let Chu Yi vomit.

However, he had to go there to find a chance to change the water quality of shallows.

Holding the bottle, Chu Yi pinched his nose to fill a bottle of water and left the stinky place.

After returning to the village, Chu Yi got into his small consulting room.

He has a microscope to see if there are microbes in the water of this shallow dragon beach.

"Eh, is there really microorganism?" Chu Yi was surprised because he found more than one microorganism in the water.

"System, I want to optimize the microbes in the water."

Then, an interface pops up in front of Chu Yi, listing the graphics of five kinds of microorganisms.

This is two more than Chu Yi can see through the microscope. Obviously, the magnification of his microscope is too low to observe the other two.

Achromobacter mutans (no optimization value)

Bacillus mutans (no optimization value)

Mycobacterium mutans (no optimization value)

Flavobacterium mutans (no optimization value)

Vibrio mutans (with a certain role in cleaning water, can be optimized)

"This mutant Vibrio has the function of cleaning water?" Chu Yi was shocked by this result. He didn't expect that there was such Vibrio in the shallow dragon beach.

He knows that there are more than 90 kinds of Vibrio, most of which can cause human diseases, but he did not expect that there are Vibrio which can clean water.

"But this cleaning ability should be very weak. It will take hundreds of years for it to clean the water." Chu Yi murmured.

"Please select the optimized microorganism." A prompt sound sounded in Chu Yi's mind.

"Vibrio mutans."

Propagation mode: amitosis (after optimization, the division speed can be increased and the propagation speed can be accelerated)

Main functions: phagocytosis of various heavy metal elements (after optimization, the types of phagocytic elements can be increased to enhance the cleaning function)

"The system, can only optimize these two, optimize both." Chu Yi touched his nose and said excitedly.

This may be the stepping stone to change his fate.

"The medium level optimization of Vibrio mutans breeding mode requires 6 energy points."

"The main function of Vibrio mutans is intermediate optimization, which needs to provide 10 energy points."

"Optimize, optimize for me." Chu Yi agreed to this plan directly, although it needed 16 energy points.

But Chu Yi knew that it was definitely a great deal.

"In optimization, the optimization will last for one hour. Please do not leave the range within 10 meters of the optimization object, otherwise the optimization will fail."

Chu Yi nodded, since the system said so, he did not intend to stay away from the water.

He also needs this drop of water to change the water quality of the shallow dragon beach.

Anyway, it's OK to be idle. Chu Yi just stares at the microscope and starts to check.

After more than ten minutes, Chu Yi found a special mutant Vibrio, which was silver and bigger than other mutant Vibrio.

"Split, start to split... Become two." Chu Yi was surprised to find that the silver mutant Vibrio actually split out one.

After a while, it became four, and it is still increasing.

At the end of an hour, Chu Yi felt that there were four or five hundred new mutant Vibrio.

"Later, I'll call you Vibrio Argentium." Chu Yi carefully dropped the sewage that produced four or five hundred silver Vibrio bacteria back into the bottle, and wrote down the time.

He wants to know how long it takes for this bottle of water to be cleaned.

"It seems that we need to build our own laboratory in the future. This bio optimization system is amazing." Chu Yi's heart gradually gave birth to a big idea.

However, he knew that a well-equipped biological laboratory would need at least tens of millions of funds.

After coming out from the consulting room, Chu Yi gave himself a bowl of noodles and squatted at the door to eat.

"Xiaoyi, you're cooking noodles by yourself. How can you be full?" Li Lianzhi just came back not long ago, saw Chu Yi eating noodles, and took the initiative to say hello.

"Aunt Li, I used to eat like this every day, and I didn't have enough. By the way, where's qiao'er's sister-in-law? She didn't come back to cook? " Chu Yi thinks Li Lianzhi is funny. He used to be very strict with himself. How could he take the initiative to talk to him.

But today, she even made love to herself one after another?

This is definitely not because I sent those fish.

Before, he didn't carry less things for their families, nor did he see Li Lianzhi like this.

Thinking about it, Chu Yi understood that it was the village head.

As for it?

The village director is only elected by the village itself, not even a civil servant, let alone a member of the system.

However, on second thought, some of them may think that the village head is already an official.

The idea that the people do not fight with the officials has affected generations.

Thinking, thinking, Chu Yi began to laugh.

"What are you laughing at? Didn't your sister-in-law go home with Yuefen, you don't know?" Li Lianzhi felt that Chuyi's laughter was strange, so she couldn't help being vigilant.
