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 flying group of sparrows from different directions.
Seeing a small group of sparrows resting in another place, Feng Yi tried it again in the same way, and once again watched them fly away in panic.
Until the sun sets in the west, the dim light of the setting sun is robbed of its presence by the street lights, and the birds fly off the branches one after another, no longer active.
At the two locations where Feng Yi had delivered "chemical information", the sparrows did not fly back for a long time after they flew away. Even if a sparrow landed on the tree there, they left quickly, as if there was something extremely dangerous there.
Apparently, the sparrows' olfactory receptors pick up on that chemical.
To put it another way, Feng Yi had a brief and unfriendly exchange of information with these sparrows.
If it is communication between natural enemies and prey, it is probably
Our side:【I’ll eat you!】
Sparrow:【Escape!!!】
Feng Yi nodded secretly, this is probably the situation.
Well, definitely.
Their flight attitude fully proves this point.
Claiming territory is probably a similar situation.
Deterrence from natural enemies!
Very useful!
It was getting late, so 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 bosses seemed to be unharmonious, with disagreements, and they had to continue the discussion in the evening, which also did not require Feng Yi and the others to participate.
Looking at the explosive chat records in the group, it can be seen that the situation has not developed in the direction that people expected. The density of starfish in the sea has become greater, and the number of fishing boats everywhere during the day has also increased...
However, these are expected and can be inferred from previous data.
Even without looking at the data, the smell information brought by the sea breeze allowed Feng Yi to confirm that in the next week, the number of starfish army would still explode. There was something to be fished for.
In addition to these, there were people who invited Feng Yi to dinner, but those people did not hold meetings. The atmosphere of the dinner without the big bosses would be more relaxed, where you can discuss academics and chat about other things, and enhance interpersonal relationships.
However, Feng Yi did have something to do today, so he refused on the pretext that he was out fishing.
I didn't go back to the dormitory, so I had dinner in several places. I was full and ready to do some work.
After eating, I rode my bicycle to the place I made an appointment with Xiao Jia.
On the other side, Xiao Jia had dinner with his fishing friends after fishing today and listened to some of the fishing friends bragging.
These people brag more than they catch fish. After two glasses of wine, they become even more uncontrollable and chatter non-stop.
That’s not to say that all fishermen are like this. Xiao Jia purposely chooses a certain type of people.
Xiao Jia didn’t drink today and said he would drive later. He listened to a few people talking about everything from a two-hundred-pound fish to swimming in a no-fishing zone.
Write down which areas are closely watched and which areas are freer.
Xiao Jia had planned tonight's course of action based on the information at hand. He agreed with them verbally, but checked again in his mind and revised the details.
When the time agreed with Feng Yi arrived, Xiao Jia said goodbye and headed for his destination.
When Feng Yi arrived, Xiao Jia was already waiting. The route had been arranged and he was ready to go at any time.
Feng Yi came to Mo City and went out to sea with the investigation team in the past few days. He didn't have a blind eye. Although he was not as detailed as Xiao Jia, he had a general understanding of what the situation was in which areas.
After confirming the route again, we set off. We also carried some fishing-related tools on the boat for cover.
After leaving the coast and driving to the original location, Feng Yi gave his cell phone to Xiao A. If someone came looking for him, Xiao A would deal with it.
After taking off his clothes and not wearing a diving suit, Feng Yi went straight into the water.
The water temperature is very cold, I don’t really like it, but it’s okay.
After entering the water, Feng Yi changed into his original form and quickly adapted to the surrounding environment.
"Then boss, I'll wait here?" Xiao Jia asked.
"Yeah." Feng Yi looked at the sky, "It's a bit windy tonight, please 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."
After saying that, Feng Yi dived down, the huge snake's tail swaying.
There were no outsiders, and Feng Yi no longer restrained himself, and fled far away in the blink of an eye.
Xiao Jia looked at the relatively calm sea and sighed in his heart, "Humans and non-humans are just different", and then took out his windproof jacket.
The temperature at night is already relatively low, and the wind that blows from time to time makes people shiver. Under such conditions, ordinary people who swim in the water without any protective equipment are looking for death.
Feng Yi is different. He is like a sea creature in the water. That is called swimming freely.
When you come out of the water to take a breath, you can dive easily for half an hour. When you dive down to 300 to 500 meters, it's like having fun. You don't feel any pressure.
This time Feng Yi swam farther, beyond the range of underwater communication and not in an area with dense monitoring networks.
Feng Yi knew the model of the underwater detector used in Mocheng waters. It avoided night patrol ships and some detection facilities and did not require navigation instruments. He could clearly distinguish the direction.
After reaching the predetermined area, Feng Yi stopped and stopped swimming to the deep sea. His purpose was not the deep sea in the first place.
Even if he is not breathing, Feng Yi can still sense the situation around him. The huge army of starfish continues to gather. As for other fish in the sea, after Feng Yi approaches, regardless of their size or temperament, they quickly move away.
Even if the original form does not deliberately release deterrent chemicals, it will still give off the aura of the top predator in the food chain.
Feng Yi didn't pay attention to the fish and dived to the bottom of the sea, thinking about how to "enclose the territory".
Feng Yi had already experimented with how to release those chemicals that had the effect of "declaring territory" during the day. This was not difficult to operate, but there was still a problem.
How much should be released?
The information obtained from ancestral DNA is to release an appropriate amount of markers within a certain range.
How big is a "certain range"?
What is an “appropriate amount”?
Release too little and it may not have the desired effect.
If too much is released, what should I do if the enclosure is half-circled and there is nothing left? I still have to get food on the spot to replenish energy?
It's not easy to do.
Feng Yi was thinking as the big tail behind him swung on the bottom of the sea.
boom!
Um?
It seemed like I had hit something.
It feels like you suddenly kicked a stone while walking...and kicked an orange, which is not very hard.
Feng Yi turned around and looked for him.
There was a half-buried metal object, and the exposed part had just been broken off by his tail.
Glancing at the buried part, Feng Yi picked up the other broken part, but he couldn't tell what it was.
The thing is a bit old, it hasn't been used for a long time, there is no current, and it has some traces of corrosion.
Feng Yi frowned.
What kind of garbage throws garbage into the sea!
It’s still metal trash!
Pooh!
When following the investigation team, Feng Yi often heard them talk about marine debris. When he saw this in the sea, his first reaction was of course marine debris!
Feng Yi didn't have time to dig it out now, and thought of digging it out later. As for the broken part, Feng Yi grabbed it and threw it in one direction.
He remembered that there seemed to be volunteers collecting garbage every week.
After throwing it away, Feng Yi continued to think about what the "appropriate amount" was.
