Picking up the flat map of the cave lake, Leng Junrui called Jian Ning and Leng Aochen, two university tyrants.

"According to the distribution and depth of the waterways in the cave, as well as the speed, direction and wind of the water, you should quickly calculate whether there are any whirlpools or rapids in this intricate waterway?"

He believes that it must be explained by the scientific method!

Leng Aochen and Jian Ning immediately started working on the map, and the spider turned on the portable computer and drew a simple 3D simulation with the starfish, but the data they input was dynamic and based on Leng Aochen's calculations.

The local fire brigade was a little surprised, "What are you guys calculating?"

Leng Junrui explained, "The strength and speed of the water flow in the cave, if there is a whirlpool underwater, you can't go down easily. ”

The captain wondered, "It's impossible, we live around here, and we've never heard of a whirlpool in it before." ”

"But that was before the flood, and now the depth of the cave is not what it used to be. Leng Junrui patiently explained that he would never let them go down without finding out the reason.

In the cave, the water flow is turbid and slightly turbulent, but it seems to be relatively calm overall, which always makes people feel that Leng Junrui is really doing this too much.

And it was this illusion of calm that deceived everyone, resulting in the destruction of ten lives (including the trapped teenager).

Janine connected the waterways inside the cave and found them to resemble a divergent funnel network.

Leng Aochen marked the depth on the floor plan that was easily overlooked, and couldn't help exclaiming: "This underwater seems to be a big funnel!"

Funnel?

In other words, because of the sharp rise in the water level, the waterways that extend in all directions in this abandoned mining area are like a big funnel once they are filled with water.

And in the center of the funnel, a huge rapid vortex is formed, capable of sweeping everything.

The fire brigade was incredulous, so the spider quickly made a 3D simulation, and as soon as the water was released......

The location of the four trapped teenagers is the center of the cave, and below them is the center of the whirlpool.

At first glance, the flow of water in this cave lake resembles a whirlpool formed by a giant washing machine, which is simply dangerous!

It is no wonder that the firefighters who were connected back then were sucked away by the underwater whirlpool with almost no chance to resist.

That kind of powerful vortex, as long as the first one is sucked up, the next five don't even have a chance to react, and they are swept away together.

So, within ten minutes, all six warriors died!

The computer simulations were played over and over again, and the firefighters could see that they were in a cold sweat.

They all have a lot of diving experience and know very well what the consequences can be in such a situation.

"Oh my God!" the captain couldn't help but fold his hands in prayer, feeling a sense of happiness that he had escaped death, "we really ......"

"So how do you go down and save people now?"

Even so, no one gave up on saving lives.

Jian Ning and Leng Aochen were still calculating accurately, "There must be a way!"

Leng Junrui ordered, "Bring us all the safety ropes!"

He observed that the safety ropes that connect the local firefighters are of short length, with only a one-metre separation between each team member.

And whether the safety rope is fixed on the shore or not, of course, is the force of the whirlpool swept violently, and it is powerless to return to the sky.

He has a plan in mind: that is, to widen the distance between the team members, increase the safety rope, increase the number of people in the water, and find a way to fix the other end of the safety rope on the shore, maybe to ensure everyone's safety.

"I'll ...... it myself later"
