It was as if a countdown was constantly ringing in his ears, and Yu Fei didn't even light up a cigarette in the darkness.

As long as Mao Xiongguo digs a safety exit after the top of the tunnel is flooded, or waits until the early morning and Mao Xiongguo doesn't think of blowing up the tunnel to seal the water flow, then he will be safe.

Breathing the air makes people feel a bit stuffy. It should be because after the air starts to be compressed by water, the pressure of the air increases, and the remaining air begins to become turbid.

Yu Fei could imagine that countless people were standing on the roof of the car at this moment, raising their heads to breathe, as if they were earning a few more breaths of air. With so many people standing together to breathe, coupled with emotional stress, the body's oxygen consumption increased.

Big, even if there is some remaining air, the oxygen contained in it will be exhausted.

Time passed minute by minute, and as the space at the top of the tunnel became less and less, the water surface rose faster and faster. Yu Fei knew that time was almost up.

After Yu Fei took out the mini-submarine he had stored in the Dragon Ball space, there was only room for one person inside.

The submarine descended slowly and the searchlight was turned on, but the water in front was very turbid and nothing could be seen clearly.

So Yu Fei had no choice but to turn on his sonar, rely on it to identify obstacles in front of him, and began to move slowly along the bottom of the water.

Sonar, something I learned from bats, is really amazing. You can judge the obstacles in front through the screen without seeing anything, and it doesn't affect driving at all.

Yu Fei just clung to the car quietly and kept moving forward. The people standing on top of the passing vehicles were almost unnoticed.

It was originally difficult for sound to be transmitted from underwater to the air, and the tunnel was very noisy now, so they were even less able to detect it.

Even after the submarine passes by, there will inevitably be some waves on the water, but this is flowing water, and all the lights in the tunnel are gone, so they can't catch these clues.

No one could imagine that someone could drive a mini-submarine in such a cool way, so even the experts didn't notice Yu Fei.

Just like that, Yu Fei turned back again. Fifty meters before reaching the predetermined position where the exit was most likely to explode, Yu Fei quietly sank the submarine into the depths of the water and began to wait.

Originally, Yu Fei wanted to save oxygen and fuel, but now he knew that people from the Bear Country would help him open the tunnel, so he stopped saving and started smoking while sitting in the submarine.

Time is still passing by minute by second. Yu Fei can't help but look at his watch. Every time he always feels that at least ten minutes have passed. However, when he looks at his watch, he finds that the maximum is only seven minutes and the minimum is only three.

minute.

This is like a psychological practice. This feeling of suffering is actually quite effective in tempering people's hearts.

Yu Fei smoked a few cigarettes and calmed down. Since he had chosen, he would just go with the flow. There were some things he could control, and some things he couldn't control. If he cared too much, it would make him feel more uncomfortable.

After adjusting his mentality, Yu Fei became much calmer and didn't want to smoke anymore, because this is a confined space, and smoking too much will bring bad air. The air purification ability of this small submarine is quite limited, and it only provides basic oxygen supply.

Just breathe.

At this moment, the chaos on the roof of the car above is still intensifying, because the water is too deep, and those who cannot swim are too submerged to stand up.

Of course, when life is in crisis, you can do anything, such as holding on to others and refusing to let go, or wanting to support others so that your own death will not feel unjust.

A feeling of despair spread throughout the tunnel. After some people went through the initial madness, they began to despair completely, so there were more and more cries.

No matter how mentally strong a person is, he will collapse in such an environment.

These men may usually be full of masculinity, but now they finally reveal their unknown side.

There was despair in the tunnel, and some people had begun to drown. Outside the tunnel, on the ground, various experts from the Bear Country, as well as military police, were digging desperately, and a big hole kept getting deeper.

Time is life. Under normal circumstances, human nature is still based on good, but most of the people behind the situation who control the situation put interests first.

So without any urging, these people worked hard to dig. When a local man's shovel touched the outer wall of the tunnel, he shouted excitedly.

Others worked harder, and soon the tunnel was dug out, covering a large area.

In order to remind the people inside, they banged the outer wall of the tunnel hard with iron tools to remind the people inside that they were coming. They also signaled the people inside to stay away, otherwise when the blast occurs, people who are too close will be splashed with debris.

To hurt.

Of course the people in the tunnel heard this movement, because the tunnel is now a closed space, and the sound can even spread far away.

When the people in the tunnel heard this sound, they all became excited and thought that they did not have to die. As long as they were still breathing, they all smiled.

However, people who were further away from here were rushing towards the exit, fearing that they would be missed during the rescue, and everyone wanted to be the first to get out of this dark tunnel.

Not to mention that the water surface was less than one meter away from the top of the tunnel, and it would be completely submerged, probably within twenty minutes.

In fact, most of the people alive now are people who can swim, or people who have found floating objects to support themselves. Their feet can no longer touch the truck.

After the people above knocked the reminder, someone quickly started to install the blasting device. This tunnel is quite strong, so if you want to blow it up, the power of the blasting device must not be small. They don't have Yu Fei's directional blasting device, just ordinary ones.

species, so after the explosion, more uncontrollable energy will be released.

Everyone on the ground evacuated outside the pit, and those who had installed the blasting devices quickly retreated. The countdown to blasting had begun.

But in the tunnel, people who were close to the explosion point all guessed that they had to keep a little distance, otherwise they were very likely to be accidentally injured. However, people in the distance were all squeezing in this way. Not only were they unable to move away, they were even trapped.

They are so tightly packed together that it is difficult to maintain swimming posture.

Even as more and more people were squeezed in, the space on the water surface was limited and even shrinking as the water surface rose, so some people were stepped directly into the water.

The darkness of human nature is undoubtedly revealed in this dark tunnel. In order to survive at this time, no one cares about who you are. No matter how high your status was before, how high your value was, how deep your background was, no one else cares.

Survival is the way to go.

Even if it's dark here, if I stab you quietly because you squeezed me, no one will know, right?

Yu Fei, who was under the water, knew that the tunnel had been dug when those people knocked on it with shovels. He didn't know it because of the sound, but because the submarine was close to the ground and the feeling of vibration came. Yu Fei was keen

perception and quickly judged it.

Yu Fei looked at the time again. There were still forty minutes until 00:00 on his watch.

No matter what, Yu Fei had to wait until that time. It was definitely not the right time to go out now.

As long as Mao Xiongguo still doesn't think about it in these forty minutes, then everything will be fine.

Yu Fei couldn't go up to the water surface, so he couldn't tell how high the water level was in the tunnel. However, Yu Fei estimated that it should be a little short of the top.

So now even if the Mao Xiong Kingdom thinks of blowing up the tunnel,

Tao, sealing the water flow is not necessarily done.

Yu Fei felt calmer and continued to wait patiently.

Boom...

The vibrations were transmitted along the ground and water to the submarine. Because the water flow was shaken by the impact, the submarine floated backwards for a distance.

At this moment, a large hole with a diameter of two to three meters was blown out at the top of the tunnel, but the tunnel was miserable.

Because everyone is squeezing in here, some people are forced to stay just below the explosion point. At the moment of the explosion, there is a terrifying shock wave and flying debris. People within five meters on the left and right sides of the hole basically belong to

They died instantly, some were shocked to death, some were beaten to death by debris, no one survived anyway.

In fact, the people squeezed here are basically the management of the tunnel, the most senior researchers and experts. They were the first to get the news, so they occupied the best position. Unexpectedly, Yu Fei spread the news. These people thought that they

I would be saved first, but I didn’t expect that I would die so simply.

However, the people five meters away were also miserable. Although the debris could not hit them due to the angle between them and the people in front, the shock wave was still spreading along the air and water, and some people were knocked unconscious.

, and then choked in the water and sank. Some people were directly injured internally. They seemed to be fine, but their lives were short-lived.

The huge energy generated by the explosion must be released, so the damage of the shock wave continues to twenty meters away. People twenty meters away just feel that the water in front of them is rushing like waves, and the air seems to have suddenly blown up a hurricane.

.

But the others didn't care about the dead people at all. The explosion had just ended, and as long as they were alive, they all rushed towards the exit.

The bodies of the people who were killed by the bombing were still hot, and the water here was mixed with blood and corpse residues, but no one cared.

After the explosion, the people on the ground rushed over with the ropes they had prepared, quickly threw them into the water, and then used lighting equipment to shine down.

Then people outside the tunnel felt like they couldn't stand it anymore, as if they had dug out hell. Because they had experienced random killings before, and because of the explosion just now, there were many corpses floating on the water inside the tunnel, and everyone alive was

His hair was unkempt and his face was stained with blood, and he looked extremely miserable.

No matter what status the people in the tunnel had before, they all lost their grace at this time.

The rope was thrown down, and someone immediately grabbed it and started climbing.

The gap leading to the human world was opened, and with the appearance of lights, the people inside finally calmed down a little, but it was only limited to the places where the lights could shine, and where the lights could not shine. Those people saw the bright light in front of them and

Everyone is trying to squeeze in towards the exit.

Therefore, the people near the exit are constantly changing. Whoever grabs the rope is easy to use. Some people were squeezed and saw the rope several times, but they had no chance to grab it.

People outside the tunnel are powerless to maintain order inside the tunnel at this moment, so they can only lift or help whoever climbs up to leave quickly to make room for the next person to come out.

It's just that this is not very efficient. Sometimes a rope is grabbed by several people at the same time, and no one is willing to let go, making it impossible for anyone to climb up.

Some people even grabbed the rope to climb, but then found that they were pulled back and unable to climb up.

The water in the tunnel is still rising, and there is already half a meter left from the top. The space for people inside to stick out their heads and breathe is getting smaller and smaller. Everyone is afraid that they will see the exit, but they have no chance to climb out and be drowned.

Die inside.

In fact, it is obvious that due to the efficiency of climbing, the efficiency of people in the tunnel to get out will not be very high. Before the water is completely submerged, only a small number of people can get out, and the remaining people can only look at the exit in despair.
