Patters followed Liu Wei's train of thought and fell into thought.

First, he should revisit the tank, which is perhaps not the largest surviving Nile crocodile in the delta of the mouth of the Rusisi River, according to the analysis of the social hierarchy.

The Crocodile King has someone else.

And it should be a very large Nile crocodile that a tank would not dare to provoke.

Otherwise, the tank will fight with it and leave scars.

Patters actually had a premonition in his heart, and after the actual analysis, he was still a little surprised.

Could it be Gustav?

Gustav was always at his side?

Patters turned his head to look at Liu Wei again.

The two looked at each other and nodded.

Liu Wei continued: "Professor Patters, the Nile crocodile often chooses to come out before the rainy season to prey on the migratory army on the grassland, and the Luxixi River is also a must for the migratory army, and the Nile crocodile will enjoy a gluttonous feast here, and then it can go without eating for a year!"

Pats said: "Yes, Liu, the migration army of the Luxixi River has not yet arrived this year, you know, the annual migration time on the grassland is unstable, but these apex predators are ready to hunt!"

Liu Wei said: "A Nile crocodile of the level of the Crocodile King usually acts alone, and before the end of the dry season, it is possible to enjoy a piece of water alone, and it is possible to stay in the cave created by itself for a long time!"

The two of them analyzed the living habits of the Nile crocodile.

All the analyses point to one goal, and that is the king of crocodiles.

Maybe it's Gustav, who has been gone for a long time.

"Professor Patters, I think I need to go into the water and observe!" said Liu Wei.

Patters said, "Liu, I don't have any diving equipment in my base!"

Liu Wei smiled and said, "I brought it!"

Back on the off-road vehicle, take off the black technology backpack, and take out the diving live broadcast equipment provided by the system.

Patters knew very well what Liu Wei was going to do, and instructed, "Liu, pay attention to safety!"

Liu Wei nodded and walked into the river, "Brothers, through my analysis and that of Professor Patters, there should be a larger Nile crocodile active here, but Professor Patters has observed it for several years and has not found its active figure, what I have to do now is to dive into the water to find the nest built by the crocodile king."

Normally, the Nile crocodile, like other freshwater crocodiles, uses its mouth and claws to build a burrow at the edge of the riverbank, but in the case of a crocodile of Gustav's size, it needs a wider and deeper location.

OK! I'm in the water! Good luck to me!"

After saying that, he jumped into the water.

At this time, the Nile crocodile floating on the water felt the water pressure and swam towards Liu Wei.

A microcomputer monitor on his head records the current situation.

The crocodiles were very curious to test Liu Wei.

Liu Wei didn't want to get entangled with it.

Facing seven or eight crocodile heads, dive straight into the deep water.

Two Nile crocodiles followed behind Liu Wei.

Their tails are full of muscle tissue, very powerful, and with a slight twist of two times, they swam to Liu Wei's side.

Liu Wei smiled slightly and continued to dive.

The speed is getting faster and the dive is getting deeper.

The deepest part of the estuary delta reaches a depth of more than twenty meters, and the comfort zone for the Nile crocodile to move in the water is five or six meters deep.

Liu Wei quickly shook off the two crocodiles, resisted the impact of the river, and moved to the right side of the river impact according to the deflection force of the floor tiles in the southern hemisphere.

Soon.

Liu Wei made a new discovery.

Located in the middle of the riverbank, there are several large caves.

There are fish going back and forth at the edge of the cave, floating objects are spreading around, and the view from the cave entrance is not very good.

Liu Wei turned on the flashlight, "Brothers, let's go in and have a look!"

The body swam in.

The further you swim inside, the deeper the cave gets.

The width of the cave is also gradually narrowing.

Liu Wei stopped, "If I go any further, my body will not be able to pass, and the space inside will not be able to accommodate Gustav's size."

What I can now confirm is that this crocodile nest has not been inhabited by crocodiles for a long time, the crocodile is a perfectionist, he likes to build his house beautifully and comfortably, the water here is strong, the mud and sand washed down from the upstream can also clog the cave, and the Nile crocodile basically renovates its home every year.

There is no sign of renovation in this cave, it has become a gathering place for fish!"

After confirming the results, Liu Wei swam out and continued to investigate along the coast.

Several of the other caves are older than the one just now.

Liu Wei went ashore directly!

Patters walked up to Liu Wei excitedly, looking expectant, "Liu, have you found anything?"

Liu Wei said: "I think it should have lived there!"

Liu Wei pointed to the direction he had just dived into, "But its nest has not been renovated for a long time!"

When Patus heard the result, his face sank, revealing his disappointment!

Still no news of it?

Liu Wei suddenly asked, "Professor Patters, in what direction is Lake Tanganico in?"

Patters replied, "It's just over ten kilometers ahead!"

"Let's take a look!"

“OK！”

Patters drove Liu Wei to Lake Tangannico, which was in the dry season and the water level was low, and the water of the Lusisi River continued to flow into the lake.

"That's where Gustav used to be before he disappeared!" Patters said, pointing to the location where he used to photograph Gustav like to stay.

"I'll go down and see!"

Liu Wei jumped into the lake.

The area of the lake is very large, and the search task is difficult.

It is difficult for Liu Wei to complete such a large amount of work in a short period of time alone.

However, Liu Wei tried his best not to let go of every suspicious place.

According to your own understanding of the conditions for crocodiles to build nests, slowly investigate.

Suddenly, a powerful stream of water rushed in.

Liu Wei realized that he had swam to the entrance of the confluence of the Luxixi River and the lake, and the river entered the lake from above and flowed out from below, forming a whirlpool.

Liu Wei could only go down the whirlpool and let the water flowing out of the lake wash his body out, which was the safest and wisest thing to do.

Float down the water.

At the exit of the lake, a pitch-black hole appeared in Liu Wei's afterglow.

Liu Wei quickly adjusted his body and swam against the current towards the black hole on the shore.

It took a lot of effort.

Grabbed a handful of aquatic plants and floated at the mouth of the black hole, turned on the flashlight and observed for a moment.

"This hole is new!"

Liu Wei concluded.

New means that it has just been renovated, and the dirt and aquatic plants on both sides of the cave entrance have left obvious claw marks and bite marks.

Based on Liu Wei's knowledge of crocodiles, this is not a good place to build a cave, and you must weigh a lot to withstand the impact of the current.

With puzzlement and curiosity, Liu Wei swam forward a little, and the flashlight hit the edge of the cave, carefully observing the claw marks left on the dirt.

"Brothers, please take a screenshot!"

Liu Wei instructed and tried to swim into the cave, but the impact of the river was too strong, and his body was swept out at once.

After rushing a few meters away, Liu Wei slowly adjusted his body balance and swam out of the water.

When Patters found Liu Wei, the two were already far apart!
