Chapter 212: Appropriate Amount

Feng Yi did not sit in that corner all the time. After the group of sparrows flew away, he wandered around the small park and observed the group of sparrows flying away from different directions.

Seeing a small group of sparrows resting in another place, Feng Yi did the experiment in the same way and watched them fly away in panic again.

Until the sun set, the faint light of the setting sun was snatched away by the street lights, and the flock of birds flew down to the branches one after another and were no longer active.

The two locations where Feng Yi transmitted the "chemical information" did not fly back for a long time after flying away. Even if there were sparrows flying to the trees there, they left quickly, as if there was something extremely dangerous there.

Obviously, the olfactory receptors of the sparrows captured that chemical substance.

To put it another way, Feng Yi had a brief and unfriendly information exchange with the group of sparrows.

If it was an exchange between natural enemies and prey, it would probably be-

Our side: [Eat you! ]

Sparrow: [Escape! ! ! ]

Feng Yi nodded secretly, and the situation was probably like this.

Yes, definitely.

Their flight posture fully proves this point.

Claiming territory is probably a similar situation.

Deterrence from natural enemies!

Very useful!

It was getting late, Feng Yi found an inconspicuous restaurant to eat, and took a look at several work-related chat groups on his phone.

The afternoon meeting of the big guys seemed to be not harmonious, and the opinions were not unified. They had to continue the discussion meeting in the evening, and Feng Yi and his team did not need to participate.

Looking at the chat records with gunpowder in the group, the situation did not develop in the direction people hoped. The density of starfish in the sea was greater, and the number of fishing boats in various places during the day also increased.

However, these were expected, and the previous data could be inferred.

Even without looking at the data, the smell information brought by the sea breeze can make Feng Yi sure that in the next week, the number of starfish will still be explosive. There is something to be gained.

In addition to these, someone invited Feng Yi to a dinner party, and those people did not have meetings. The atmosphere of the dinner without the big guys will be more relaxed. We can discuss academics and chat about other things to improve interpersonal relationships.

However, Feng Yi did have something to do today, so he refused the invitation with the excuse that he was fishing outside.

He did not return to the dormitory, but changed several places to have dinner. It would be better to work after eating.

After eating, he rode his bicycle to the place he had agreed with Xiaojia.

On the other side, Xiaojia had dinner with his fishing friends after fishing today, and listened to several fishing friends bragging.

These people brag more than they catch fish. After two glasses of wine, they are even more out of control, and they keep talking.

It’s not that all fishermen are like this, Xiaojia chooses a certain type of people with a purpose.

Xiaojia did not drink today, saying that he would drive later, and listened to several people talking about the big fish of 200 kilograms and swimming in the prohibited fishing area.

Which areas are closely watched and which areas are more free, all this information is recorded.

Xiaojia had already formulated the action route for tonight based on the information at hand. He agreed with them verbally, checked again in his heart, and modified the details.

When the time agreed with Feng Yi came, Xiaojia said goodbye and headed for the destination.

When Feng Yi arrived, Xiaojia was already waiting, and the route had been arranged, ready to go at any time.

Feng Yi followed the investigation team to the sea in the past few days in Mocheng, and he was not completely in the dark. Although he was not as detailed as Xiaojia, he had a general understanding of what the situation was in each area.

After confirming the route again, he set off. There were also some fishing-related tools on the boat for cover.

Leaving the coast and driving to the original location, Feng Yi gave Xiaojia his mobile phone. If someone came to him, Xiaojia would deal with it.

Feng Yi took off his clothes and went into the water without wearing a diving suit.

The water temperature was very cold, not very fond of it, but it was okay.

After entering the water, Feng Yi changed into his original form and quickly adapted to the environment around him.

"Then boss, I'll wait here?" Xiaojia asked.

"Yeah." Feng Yi looked at the sky, "The wind is a bit strong tonight, keep warm."

How to deal with different situations has been discussed before, so there is no need to say more.

"Okay, that's it. I'll go first."

Feng Yi dived with his huge snake tail swinging.

Without outsiders, Feng Yi no longer restrained himself and rushed far away in the blink of an eye.

Xiao Jia looked at the relatively calm sea surface, and sighed in his heart, "Humans and non-humans are different", and then took out his windproof jacket.

The temperature at night was relatively low, and the wind that blew from time to time made people shiver. Under such conditions, ordinary people would go swimming without any protective equipment, which would be a death wish.

Feng Yi was different. He was like a marine creature in the water, and that was called swimming freely.

He came out of the water to take a breath, and it was easy to dive for half an hour. He dived three to five hundred meters like playing, and he didn't feel any pressure.

This time Feng Yi swam farther, beyond the coverage of underwater communications, and was not in the dense monitoring network area.

Feng Yi knew what type of underwater detector was used in the waters of Mocheng. He avoided the night patrol ships and some detection facilities, and did not need navigation instruments. He could clearly distinguish the direction.

After reaching the designated area, Feng Yi stopped and no longer swam into the deep sea. His goal was not the deep sea.

Even without breathing, Feng Yi could still sense the surroundings. The huge army of starfish continued to gather. As for the other fish in the sea, after Feng Yi approached, no matter their size or temperament, they quickly moved away.

Even if the original form did not deliberately release deterrent chemicals, it would still reveal the breath of a top predator in the food chain.

Feng Yi ignored the fish and dived to the bottom of the sea, thinking about how to "mark the territory".

Feng Yi had already experimented with how to release the chemical substances that "declare the territory" during the day. This is not difficult to operate, but there is still a problem.

How much should be released?

The information obtained from the ancestral DNA is: release an appropriate amount of markers within a certain range.

How big is the "certain range"?

What is the "appropriate amount"?

Releasing too little may not have the expected effect.

If too much is released, what should I do if there is nothing left halfway through marking the territory? I have to eat on the spot to replenish energy?

It's not easy.

Feng Yi was thinking, and the big tail behind him was swinging on the seabed.

Bang!

Hmm?

It seems to have hit something.

It feels like kicking a stone while walking... kicking an orange, which doesn't seem to be very hard.

Feng Yi turned his head to look for it.

There was a half-buried metal object, and the exposed part was just cut off by his tail.

After taking a look at the buried part, Feng Yi picked up the other broken part, but couldn't tell what it was.

The thing was a little old, hadn't been used for a long time, had no current, and had some signs of corrosion.

Feng Yi frowned.

What kind of rubbish was throwing garbage into the sea!

Or metal garbage!

Pah!

When following the investigation team, Feng Yi heard them talk about marine garbage a lot. When he saw this in the sea, his first reaction was of course marine garbage!

Feng Yi didn't have time to dig it now, thinking about coming back later to dig it. As for the broken part, Feng Yi grabbed it and threw it in a direction with great force.

He remembered that there seemed to be volunteers collecting garbage every week in that piece.

After throwing it, Feng Yi continued to think about what the "appropriate amount" was.

A short chapter.

See you tomorrow~
