Yu Fei drove the submarine forward cautiously and slowly, and even bumped into the body sinking to the bottom. He simply pushed it forward. As long as the propeller behind it didn't get entangled, it would be fine.

In this way, Yu Fei quietly moved to the position directly below the exit. Then he adjusted the submarine and adjusted the submarine's diving depth to the limit. Of course, the submarine could no longer sink. In fact, this was to store more water in the submarine.

Add weight to fight the huge current that will follow.

Even this was not enough for Yu Fei, so he took out a lot of heavy objects from the Dragon Ball space and placed them in the limited space inside the submarine to increase the submarine's weight.

At this moment, everyone at the exit was still scrambling to climb out, because the water surface had risen high enough. Some people even stopped using ropes and started climbing by grabbing some of the irregular edges created by the explosion.

From the ground, it looks like a terrifying hole leading to boundless hell. People are constantly crawling out of it. These people are covered in mud or blood. Some people have facial expressions under the influence of extreme fear and other emotions.

It was very scary. Some people seemed to be stupid after crawling out and stayed in place without saying a word. Some people seemed to be crazy after crawling out, crying and laughing at the same time, and so on.

Everyone who climbed out seemed to have just escaped from the scythe of death. The feeling of surviving the disaster was expressed in different ways for everyone.

Although people are constantly escaping, the number of people who have escaped is still too small compared to the number of people in the tunnel. Most people are still squeezing in this way in despair and full of hope.

The water surface is from the top of the tunnel, and the highest position is just enough for a person to stick his head out.

People who can't swim have basically drowned, because this height, even if there are floating objects, is not enough for people to breathe through their buoyancy.

Some people couldn't get the best position, so they could only work hard at the edge to stretch out of the water to breathe.

From time to time, someone cannot hold on and is about to sink. When people are drowning, they will grab every life-saving straw they can, and then people are constantly being pulled under the water.

Yu Fei inside the submarine took one last look at the time, and there were two minutes left.

This was the last time Yu Fei checked the time. He took out the helmet that had not run out of oxygen and put it on. He threw away all the useless things on his body and put all the submarine's counterweights under his feet. In the end, he only left enough to curl up.

With so much space, you can just grab the handle of the submarine's hatch with both hands, and at the right time, you can open the hatch and rush out.

Yu Fei has long thought about the possibility of a heavy siege outside, but he is confident that once the main road of the underground river is blasted, he can escape. Another reason is that the water level of the underground river is much higher than here.

.

Once it is blasted through, the water pressure formed by the incoming water can form a fountain-like, crazy outflow at the blasted hole.

At that time, you can rush out with the current, and then run directly. As long as they don't see your face clearly, they will only think that they are crazy. Even if they are chasing you, it is to save themselves, so they shouldn't

many people.

Yu Fei sorted out his plan in his mind, and then began to wait for the explosion.

But the people outside the exit had no idea what was going to happen next, and the people inside the exit who were still trying to escape had no idea what was about to happen.

The top brass of the Mao Xiong Country breathed a sigh of relief after hearing that the tunnel had been blown open and rescue operations had begun, thinking that they could recover some losses.

Just when everything was so painful but moving forward normally, the bomb that had been planted in advance beside the main channel of the underground river finally exploded.

At the moment of the explosion, terrifying energy was released, and the surrounding soil was violently pushed away. The main channel of the underground river was instantly opened on one side, and the main channel of the underground river was opened on one side.

This blasted through the already wide gap in the tunnel that had been hit by the water flow.

Rumble…

The moment after the explosion ended, the terrifying water in the underground river began to surge toward the gap crazily, and the ground seemed to tremble.

From the gap created by Yu Fei's explosion, terrifying water flowed into the tunnel, and the strong pressure pushed the water flow very fast.

The remaining space was filled with water almost instantly, and the air was pushed toward the exit here.

The people who were escaping felt that the wind began to blow in the narrow space in the tunnel, and the air began to flow actively. They seemed to hear a sound like ocean waves.

The explosion that was far away from here occurred underneath. Yu Fei's settings did not require the explosion to penetrate the ground to prevent the water pressure from being leaked. This resulted in the sound of the explosion not actually spreading very far.

The people in the tunnel didn't know what they were about to face. They hadn't noticed anything unusual about this, and they were still squeezing out of the exit.

But as the water in the main channel of the underground river got closer and closer, they could finally hear more and more clearly because the distance was close enough.

Rumble…

The terrifying noise made those who had not escaped and the people outside the cave feel very uneasy and knew that something bad must have happened.

But when they had this premonition, within a few dozen seconds, everything suddenly changed.

The terrifying water flow swept over, and the people in the tunnel suddenly felt that they had lost control of their bodies. They were carried by the terrifying water flow and began to move forward rapidly. At the end, there was no air left.

The rescuers outside the cave entrance saw that the people below were suddenly swept away by the terrifying water flow. Even because of the water pressure, the people inside the cave entrance began to rush out crazily along the entrance of the cave. The huge hole several meters wide rushed out.

The water that comes out can actually rush two to three meters into the air.

This is because the space in the tunnel has not been completely filled, and most of the water pressure is still pouring toward the other end of the tunnel, so a lot of it is released.

Yu Fei, who was hiding deep under the water, also felt the horror of the water flow. Because of the terrifying water flow, the cargo on the truck was impacting and flying around, causing the truck to move due to the impact.

The submarine, which he had heavily weighted, was actually moved in the direction of the current.

Yu Fei originally planned to stay in the submarine until the tunnel was completely filled, and then go out, but this actually caused him to deviate from the entrance of the tunnel.

But Yu Fei couldn't go out at this moment. No one knew what was being carried by the current. Once he was hit, the result would be difficult to predict.

So even though he felt that the submarine was moving, it was also protection for Yu Fei. When he heard the clang of something hitting the submarine, he could think of what he would suffer if he went out alone at this moment.

Didi...

Suddenly the instruments inside the submarine start to sound an alarm. This alarm sound is usually caused by a situation that threatens the safety of the people inside the submarine.

But because Yu Fei stuffed too many things inside, he could no longer see the display screen, so he couldn't judge what to do. He would hold on for a while and wait until the water flow became more stable, then he would go out. As long as

It would be nice if the submarine didn't explode.

boom……

The submarine didn't know where it hit and stopped suddenly.

Didi, didi, didi...

The sound of the submarine's alarm became louder and more urgent.

Yu Fei suddenly had a bad sixth sense. He thought before that as long as the submarine didn't explode, it would be fine. Now he guessed that this thing was most likely going to explode.

Yu Fei knew he had to get out. He hurriedly twisted the handle and tried to open the submarine.

Boat hatch.

But at this time, his expression changed, because the hatch seemed to be deformed, and he turned the handle, but the hatch could not be opened.

Yu Fei took a deep breath and summoned all his strength to try, but failed again.

Because submarines have to withstand huge water pressure, the metals they use are all high-grade alloys, and their strength is beyond what ordinary metals can achieve. The shell may have deformed due to the heavy impact just now.

Since brute force cannot open the hatch, we have to find another place. The next easiest place to escape is the special glass in front of the submarine that allows for underwater viewing.

Yu Fei hurriedly and frantically put the counterweights and various metal objects he took out into the Dragon Ball space, and then he could finally see the submarine's control screen.

"The hydraulic system is damaged and the hatch is locked and cannot be opened. Warning!"

"Insufficient power, all power systems are about to shut down!"

"Please leave the submarine immediately!"

"The fuel tank is leaking and it is impossible to return!"

…

Yu Fei was shocked when he saw the screen. This mini-submarine was indeed unreliable. So many problems appeared at once.

Yu Fei glanced at the glass in front and finally understood that it was not just the shell that was deformed, but the hydraulic system that locked the hatch. The water was basically incompressible, so he couldn't open the hatch.

Now I have to break the glass and rush out. This is the only way.

He took out two powerful mobile phones, pointed them at the glass in front, and fired fiercely.

Bang bang bang!

Yu Fei only had time to fire three times before the glass shattered, and the incoming water made the bullets fired from the pistol, which was not a firearm that could be used underwater, lose their effect.

But the glass was broken, and that was enough. Yu Fei hurriedly reached out and grabbed the edge of the window and got out.

The water outside was very turbid. Yu Fei turned on the lights on his helmet, but he could only see more than ten centimeters away.

However, the water flow began to slow down. Yu Fei knew that this was the space inside the tunnel, which was basically filled with water, so the water in the tunnel became stable.

The next step should be the exploding exit from the Bear Country, which is surging outward crazily.

But Yu Fei didn't even know how far he had just been rushed out.

The water on the other side of the outlet should flow relatively fast, but this end is a dead end, so it won't flow much after it's filled.

Although he couldn't see the surroundings clearly, Yu Fei could guess that there must be a lot of floating debris on the top of the water, occupying the top space, and below were trucks and other items, which were also obstacles.

Therefore, it is best for him to return close to the wall on the middle floor. The chance of encountering obstacles is the smallest. Even Yu Fei is not worried. He is holding a stick in his hand, like a blind man's stick, stretching out in front of him.

Prevent yourself from swimming too fast and hitting an obstacle directly. If you are unlucky and hit a sharp point, your helmet will be broken, which will be in trouble and will seriously affect your movements.

As Yu Fei moved forward, a lot of debris floated past his helmet, but the debris was easy to deal with. The most uncomfortable thing was that he kept encountering drowned corpses.

Those corpses floated past it very close to it, and some of them were really terrifying when they saw their faces. Yu Fei was not afraid of anything, but he still couldn't bear to see those people's horrific death faces.

However, Yu Fei's heart was as solid as stone. He only felt uncomfortable for a while, and then he could ignore it. The most important thing now was to find the exit, escape along the current, and then leave here quickly to prevent the Bear Country from thinking of a way to stop the current.
