After listening to Fang's analysis, the water friends were shocked.

[Damn, then it’s not invincible underwater? 】

[This is too strong. It turns out that the one Lao Fang dealt with before was weakened. 】

[Then how to catch? Seduction? 】

[It can only be seduced, right? It seemed to come out easily last night]

Not only that, Professor Gu Qingyuan’s next words made the water friends realize that the situation was more serious than they thought.

"This creature still exists today, which shows that it has already adapted to the environment here, and it is also an area like Qaidam that has hardly been disturbed by human activities. In other words, it has no possibility of functional extinction!"

"There is a population here!" Bifang blurted out, directly saying the second half of what Gu Qingyuan wanted to say.

But the audience is confused, what is functional extinction?

Facing the barrage of questions from water friends, Bi Fang gave a simple explanation.

"Any species that wants to continue must have a minimum population size in order to cope with accidental changes in individual birth and death, genetic drift, a series of random changes in the environment and various catastrophic events."

"Below this number, the species itself will become functionally extinct! They will no longer be able to reproduce themselves!"

“Therefore, functionally extinct species are called ‘zombie species’, and their last remaining individuals are called ‘living dead’.”

"The most famous example is probably Lonesome George. Even if he is still alive, the Pinta Island tortoise is actually extinct."

There are many such species in nature, just like the Siberian tiger today!

If they breed with other tiger populations without human intervention, no matter how good their living environment is, they will have various problems due to inbreeding, and they will become extinct naturally within a few decades!

In other words, there are many more monsters like last night under the pool!

Just when the water friends thought that the danger of this matter was over, Gu Qingyuan did not let them go and threw another bomb.

"I'm afraid it's not just that Tiktalik here may be more dangerous than it was 300 million years ago. Do you know the famous fossil creature in Qaidam, Wu's Xianyu?"

"Understand one thing, a fish with incredibly strong bones would have been a disease for any other fish." Bifang wiped the sweat from his forehead.

The wilderness survival skills given to him by the system are no longer of use at this moment, because the knowledge about animals and plants it gives him are basically non-extinct creatures.

This kind of creature, which has been extinct for millions of years, has long gone beyond the scope of knowledge about survival in the wilderness. Only knowing it depends on the accumulation in the previous life.

"Yes, the bones of Wu's Xianwen fish are incredibly thick. The only fish similar to it is the thick-tailed medaka. These two creatures lived in similar environments at that time, and they were both products of environmental aridity.

"Although there is no conclusion yet, we have always suspected that the thick bones of Wu'er's fish are related to this environmental change."

"Let's put it this way, I think Tiktalik, who has also gone through this process, may also undergo the same changes."

Gu Qingyuan expressed his speculation and gave some suggestions.

"If capturing it alive is impossible, I suggest that when you encounter danger, try to use blunt weapons to attack it, or look for the joints of the bones. Otherwise, it may be difficult to injure it with an ordinary knife."

[What do you mean? Why can’t I understand it? What does this have to do with Wu Shayu?]

[If you don’t understand plus one, please explain. Your conversation is too high-end.]

[My teacher told me to study hard, but I didn’t listen. I didn’t regret it until I went to work in a factory. But now, I can’t understand the live broadcast and am crying.]

[Stop crying, even those who graduated from 211 are so confused]

"To put it simply, the fish here may have stacked armor."

If what Gu Qingyuan said is true, then the bones of Tiktalik here may be much harder than imagined. Compared with the original ones, are they just a layer of armor?

[If I had said this earlier, it would have been over...]

[Damn, how are you going to fight like this? The opponent is already in a state of ecstasy, and he even defeats Fang’s dagger!]

【Why don't you just give up and live a good life? 】

"But after surviving, there will be many opportunities to discover new living fossils, which may only happen once in a lifetime."

Bi Fang was not moved at all, but was eager to try. He went straight to the water pool. Because it was daytime and there was enough light, the water pool was very clear at the moment. He could clearly see the surrounding rocks more than two meters down.

What does an underground cave look like?

What kind of creatures are there?

Bi Fang was very curious about this. He held the flying drone in his arms and pretended to dismantle the camera. In fact, he reshaped the live broadcaster into a head-mounted camera and placed it on his head.

"Don't you want to see the living environment of this creature? What does it eat? Its range of activities, the composition of the food web, is it clustered? What are its habits?"

I do, of course I do.

Behind the screen, Gu Qingyuan nodded desperately, but as he nodded, he suddenly froze.

Gu Qingyuan scratched his gray hair and felt that there seemed to be something wrong.

wrong.

Something is wrong.

Didn't we agree to catch a live Tiktalik?

Just like last night, just make some bait or something and trap Tiktalik ashore. How can you know so many things?

But when he saw Bifang starting to take off his clothes, a current suddenly connected to Gu Qingyuan's brain, causing the brain to shut down.

It took a while before it was reconnected to the Internet before it burned out.

Depend on!

This kid wants to go into the water and catch him!

【Absolutely not possible!】

How can you go into the water and catch it?

Isn't this the old man who hangs himself because he thinks he has a long life?

But the barrage sent by Gu Qingyuan had already been submerged in the sea of ​​bullets.

Bi Fang didn't even look at it.

"Since there are such huge creatures in the underground river, there must be more than just this small exit, otherwise the amount of oxygen would be a problem, so I think there should be many exits under the pool, and there may even be an underground world."

After taking off only his pants and lining, Bifang put all the extra clothes into his backpack. He lay down by the pool and observed carefully.

Not sure if it was an illusion, but he always felt that there was a fishy smell in this pool.

"This is made up of a pile of talc. Due to wind and sand, there is a lot of sand underground. There should be other channels below connecting to the underground river. This is a water cave!"

"Water caves are much more dangerous than land caves. Once you get lost underwater, you can easily drown. So don't wait until there is insufficient oxygen to think of returning to the entrance. Otherwise, it will be too late."

"If you encounter this situation, don't panic. The more panic you have, the greater your oxygen consumption will be."

"The only thing we can do is to reduce consumption and follow the water flow. Where there is water flow, there must be a channel. And by following the water flow, we can also reduce oxygen consumption."

Because I won’t be able to talk until I get into the water, Bi Fang wants to explain the key points to everyone clearly first.

Then, he took a few deep breaths, put on his backpack, put on his camera, and jumped directly into the pool!

Just hearing a "crash", the audience watched Bifang jump into the deep pool.

Following the camera's perspective, the audience only felt that it was pitch black under the pool. In the closed environment, many water friends had begun to have difficulty breathing.

Silence, deathly silence.

Unknown monsters lurk in the deepest depths, just waiting for their prey to fall into the trap!
