Chapter 119: The Prisoner's Dilemma, Bullets in the Dark

The sudden change, Long Xiaoyun's face also changed.

At this moment, a communication sound came from Long Xiaoyun's terminal watch.

"Colonel Long, we found a huge cave outside, and there are artificial thrifts in it, but we can't go down." This is Zhang Lu's voice.

When the grenade exploded, debris flew from the rock wall, revealing a swarthy hole.

"What a discovery!"

Tian Guo was overjoyed and urged Zhang Lu to go up to investigate together.

When the two climbed up to the hole in the rock wall, they found the entrance to a corridor.

But this entrance, unlike the previous one, was parallel to the entrance, but this one was vertically downward.

Zhang Lu used a military flashlight to shine downward, which was unfathomable, and the light source could not reach the bottom of the road, so it was impossible to know the depth of the road.

It is not so much a road as a deep well, which has been poured concrete, and the surrounding area is smooth, and there is no point of focus to climb.

Tian Guo is experienced, picked up a piece of gravel and threw it towards the center of the well.

"Do you hear an echo?" Tian Guo has been listening carefully, but he can't hear anything, the echo is too small, it seems to be there, and it doesn't seem to be.

"I heard a little bit, probably three seconds after you threw it down." Zhang Lu replied.

His body has been strengthened with seed essence, and his hearing has also improved to a certain extent.

The speed of sound propagation in the air is about 340/, and the higher the temperature, the higher the propagation velocity, the higher the propagation velocity.

This speed is too fast, just counting the free fall of the stone, then this deep well is at least about 30 meters deep.

At such a depth, the flying claws can barely go down.

"Do you want me to go in and investigate?" Tian Guo proposed.

"The situation below is unclear, and it is too risky to enter rashly." Zhang Ludao: "You can start from the previous Yongdao, I guess most of these Yongdao are figured out." ”

"The brain is the light." Tian Guo praised: "How did you find out that there was a problem with the rock wall?" ”

"It's cloudy, the rock wall is bare, and there are not a few more weeds!" Zhang Lu said casually.

This is naturally not blind.

Static photosynthetic warning, for the occurrence of massacre, if you carefully investigate, you will find clues.

The corridor is sealed, and the residual breath is strongly concentrated in the corridor, so the decibels of the humming sound are extraordinarily loud.

"So what do we do now?"

"I'll talk to Long Xiaoyun first, report the situation, and see if they can find here."

The other side.

Long Xiaoyun still remembered to answer Zhang Lu, the poisonous gas had begun to spread.

Dongyi, who was a soldier, immediately ordered: "Hold your breath, the corridor is too small, don't panic, retreat in an orderly manner." ”

The most feared thing is that this group of students was frightened and panicked, causing a stampede and affecting the evacuation.

While maintaining order, Dong Yi and the three people organized expert students to retreat and return to the entrance of Yongdao along the road.

Just as the crowd was exiting the corridor, they ran towards the entrance.

There was a loud bang.

Everyone felt the earthquake in Yongdao.

Finished!

Everyone was stunned.

A huge stone gate fell on the road, just like the broken dragon stone in the ancient tomb, completely blocking the road.

Poisonous gas is pervasive.

The foul, disgusting smell came.

The young students were terrified, and their lips were white and there was not a trace of blood.

"What to do, we can't get out, we're all going to die here!"

"Help us, I don't want to die here!"

"Find a way to get out, hurry up...... When the gas disperses, we will all be poisoned. ”

"How can this be, how can this be ......"

“……”

Sounds of horror and despair were heard from time to time.

Rao is one of the experts who have lived for most of their lives, and in the face of death, they are all pale and panicked.

"Shut up! Take a deep breath and save a little more gas while the gas has not yet dissipated. ”

Dong Yi broke off and rushed to the stone gate.

I saw him holding the butt of his gun and slamming it on the stone door.

The sound of the impact was deep and silent.

Dong Yi frowned, turned around and shook his head at Long Xiaoyun and the others.

If the stone door is not thick, then the impact will not be so heavy, they can use firearms, and then use brute force to break through the stone door.

Now the stone gate is too thick, and Dongyi shook his head, just to tell everyone that brute force can't break it, and the only way is a grenade.

But grenades must be used with caution.

Because they are in the corridor, if the explosion of a grenade is powerful, if the corridor collapses, then everyone will have to die here.

This road is the main road, there is no second way to choose, and no one can get out without breaking the stones.

Long Xiaoyun's face was shocked, he had explored the Yongdao several times without incident, why was it suddenly in danger?

This sudden change disrupted everyone's exploration plan and blocked their way to survival.

Careless.

But it's useless to regret now, the only thing you can do is to find a way to get out, otherwise you can only be trapped and die in the corridor.

Dong San reacted quickly, took out three electronic devices from her backpack, and she counted the number of people, a total of 18 people.

Immediately, he said loudly: "The poisonous gas has begun to diffuse, hold your breath, I really can't stand it, just take a breath, oxygen is not infinite!" ”

The three electronic devices are military oxygen supplyers, which can provide oxygen.

It's just that the oxygen supply can't be infinite, it can only be provided for 15 minutes, but there are 18 people on site.

Three oxygen supplies, how long can they last, Dongsan has no bottom in his heart.

"If it doesn't work, blow open the stone door!"

Dong San showed a touch of determination.

It's just that no one can guarantee that the tunnel will collapse and the situation will get worse.

The poisonous gas in the corridor hit, and the corridor was blocked by the stone gate.

The crowd is like a rat in a bellows, caught in a dilemma, tormented in despair.

Long Xiaoyun thought that Zhang Lu was still outside, and there was still a weak signal at the moment, and he just wanted to communicate.

Bang!

Sudden gunshots rang out.

A military flashlight in the hands of a gray-haired expert fell to the ground, and then suddenly fell to the ground.

"Mr. Kim......"

The student screamed in horror, and the flashlight shone at Mr. Jin, who fell to the ground, only to see him covering his chest, and blood gushed out from his fingertips, staining all the plackets on his chest red.

Yes......

Screams of horror erupted.

"If there is an enemy, lie down ......"

Dong yelled loudly, and his body rolled on the spot.

Bang!

A second gunshot rang out.

The bullet was aimed at Dongyi, who was warning him, and the angry bullet whistled in.

Seeing that the situation was not good, Dong Er flew and pushed Dong Yi away.

Poof.

Dong Yi was not shot, but Dong Er, who flew in, was hit by a bullet in the shoulder blade, and suddenly blood exploded and blood mist sprayed.

"Enemy attack!"

Dong Yi hugged Dong Er and rolled to the corner of the road.

Da Da ......

Tosan reacted quickly, judging the trajectory of the bullet from the direction from which it came.

But the corridor was pitch black, and the light source of the flashlight could not shine that far.

Tosan threw away his military flashlight, and the three of them wore night vision devices.

Dong San held the barrel of the gun in his left hand, pulled the trigger again and again with his right finger, and shot wildly.

Dongsan can't lock the enemy's position, so he can only rely on his combat experience to fuzzy sense.

The sound of gunfire pushed everyone's situation up to the precipice at once, and no one knew that they would be shot and killed in the next moment.

Explosions, sudden sinking stone doors, gunshots.

These three things are linked, and that is a premeditated interception!?

Rao is Long Xiaoyun felt the crisis of death, and she was quite calm, and she did not hesitate to communicate with Zhang Lu.

"We are trapped, come to the rescue, there are enemies here, someone is injured, ...... quickly"
