The most dangerous thing was that as the flames burned, Wei Wu and the others felt like they were trapped in an oven.

Because this cave is basically made of rock except for the ground, the heat can be fully refracted.

So even though the fire had just started, the temperature in the cave immediately rose sharply.

The key is that as the flames continue to burn, the oxygen in the cave will become less and less.

If you can't escape quickly, even if you don't suffocate or burn to death, you will be choked to death by the smoke produced by the burning.

No one expected such a sudden change, and no one knew how the fire started.

Although when the flames started, Wei Wu's first reaction was that it was Lu Yao's doing.

But when he turned around, he found that Lu Yao was looking at the fire at the cave entrance with a look of panic on his face.

According to common sense, the most suspicious person at the scene is Lu Yao, but looking at his expression, he doesn't look like that.

The key point is that Lu Yao himself was trapped in the cave.

Unless he wanted to die together with his enemies, he would not do such a stupid thing.

However, regardless of whether it was Lu Yao's doing, Wei Wu had no time to think about this issue now.

The most important thing right now is to find a way to escape, otherwise you will surely die.

However, just as Wei Wu was thinking about countermeasures, a sound of breaking through the air suddenly rang out.

Then, an arrow flew through the raging flames, passed by his head, and hit the rock wall in the cave.

Wei Wu reacted and suddenly raised his hand, made a downward gesture, and then shouted loudly:

"Everyone, attention! There are archers outside. Stand against the wall!"

Upon hearing Wei Wu's voice, Shen Lin, Zhang Hai and the members of the Wuchang team immediately lay on the ground.

Among all the people, only Lu Yao was standing stupidly against the rock wall in the cave.

Only when he saw Shen Lin and the others all lying on the ground did he react and prepare to follow suit.

However, at this moment, the second wave of arrows also emerged from the flames.

Before Lu Yao could lie down, he was shot by an arrow and hit his left arm and shoulder.

But in the end, the shot did not hit the vital part, and Lu Yao still managed to fall to the ground.

At this moment, Wei Wu's voice was heard again in the cave.

"Everyone, free fire!"

Although they were lying on the ground, Shen Lin and others reacted quickly.

Upon hearing Wei Wu's order, he immediately picked up the M4A1, and completed the safety and loading actions in one go.

boom! boom! boom!

A series of gunshots rang out, and a scream was heard outside the cave.

However, before Shen Lin and the others could continue shooting, six arrows flew out from the flames again.

Judging from the number of arrows, there are no less than six people outside.

Fortunately, Wei Wu and the others were lying down, so the arrows failed to cause any damage and only hit the rock wall inside the cave.

But everyone understands that lying down is not a long-term solution. There is a raging fire inside and archers outside.

After a long time, even if you are not shot to death by arrows, you will be burned to death by fire unless you can rush out.

The problem is that this is simply impossible. Even if Wei Wu takes the car out of the system space, it will be useless.

The cave is in the shape of a gourd. It is quite spacious inside, but it becomes narrower as you get closer to the entrance.

It can be said that the situation has reached a point where one is on the verge of death.

The cave was filled with smoke and the temperature was getting higher and higher.

Several members of the Impermanence Team have begun to experience respiratory distress.

Seeing that there was really no other way, Wei Wu took out a gas mask from the system space and put it on his head.

He only got one of this thing from the express delivery, and since he couldn't distribute it, he had to use it himself.

Then he took out the explosion-proof shield he had used before, stood up and walked directly to the front of the tunnel entrance, holding the explosion-proof shield in front of him.

As a result, I felt two impact forces when I stood it up, but fortunately no dangerous situation occurred.

Next, under Wei Wu's command, everyone crawled behind him in an orderly manner and entered the tunnel.

Only after everyone entered the tunnel did Wei Wu quickly speak:

"Quick! Tear off your clothes, soak them with urine and get stuck at the tunnel entrance. Close the secret door tightly to prevent the smoke from getting in!"

When everyone heard this, they immediately started to act according to Wei Wu's instructions.

Soon, a few diapers appeared on the edge of the secret door of the tunnel, and then there was a clang.

The metal secret door was closed tightly, and not a trace of smoke could get in.

It was not until this time that Wei Wu finally breathed a sigh of relief and no longer had to worry about any danger for the time being.

In fact, if Wei Wu had not had no other choice, he really didn't want to retreat into this tunnel.

The reason is very simple. This tunnel is like a jar. Once you enter it, you can't get out.

He didn't know what was happening outside, not even when the fire went out.

In addition, the metal secret door is already very thick, so those people can seal it with just a little effort.

Then they would be completely trapped in this tunnel.

It turned out that Wei Wu's guess was correct, just when everyone thought it was safe.

boom! !

Suddenly, a loud noise erupted from the cave outside the secret door. Upon hearing this sound, Wei Wu's face instantly turned gloomy.

Dynamite!

Those bastards outside actually have explosives in their hands!

And it exploded in the cave, it was going to bury us alive in this tunnel!

Just as Wei Wu was guessing in his mind, the sound of rolling gravel came from outside the metal secret door, confirming his guess.

But this is not the worst. What really makes people despair is the sound of collision coming from the metal secret door.

The worst happened, the metal secret door was crushed by the collapsed rocks in the cave.

When the chaos outside stopped, Shen Lin hurried to the secret door and tried to push it open.

However, no matter how hard he tried, the metal secret door did not move.

The key point is that the space in the tunnel is narrow. It is more than enough for one person to pass through, but there is no room for two people to stand.

Even if we tried to concentrate all our manpower to push the door open, we couldn't do it.

"Alright, Shen Lin, come back! Don't waste your energy. This door can't be opened. Put out all the torches and come and rest."

In fact, Wei Wu was not worried that Shen Lin’s efforts were in vain, he was mainly worried that there was not enough oxygen.

This is also the reason why he asked Shen Lin and others to extinguish the torch. Burning will also consume oxygen.

Although the cellar space connected to this tunnel is not small, it is now a completely enclosed environment.

While consuming a lot of physical strength, it also consumes their remaining little oxygen.

Seeing Shen Lin retreat obediently, Wei Wu took out a flashlight and turned on the diffuse light mode.

Then he sat down on the ground and fell into deep thought.

Seeing that Wei Wu was thinking about something, Shen Lin didn't dare to disturb his thoughts. After coming back, he stood by and guarded him.

Just like that, the entire cellar fell into a dead silence, which lasted for about three minutes.

Wei Wu, with confused eyes, suddenly came back to his senses and looked at the ground. Then he grabbed a handful of soil and rubbed it slowly.

Everyone looked at Wei Wu, wondering what was wrong with him.

At this moment, Wei Wu suddenly spoke, and said with a slightly self-deprecating tone:

"I was so careless that I didn't even notice such a simple thing. I deserve this disaster!"

After saying that, Wei Wu turned to look at Lu Yao again and said in a cold tone:

"But you've already achieved your goal, so why are you still pretending? Or do you insist on me going through a process before you confess?"
