Liu Kun motioned for Ah Lian to lie down, and then propped himself up, allowing Ah Lian to retreat from under him to the back.

It's just that the passage is too short, and the two of them have to work hard to swap places.

Sticking out his head, Liu Kun saw the room below clearly.

It was empty, with a large iron gate on the left and right, which looked very heavy at first glance, and there were red letters and warning signs written on it.

Seeing the sign, Liu Kun's pupils shrank sharply, and he immediately retracted his head.

There is a skull drawn inside the yellow triangle, where is this vault, obviously a gas chamber!

"This is not a vault, this is a place where devils store poison gas."

"What?!" Ah Lian was so shocked that she almost cried out.

Liu Kun signaled to retreat first, and the four of them returned to the fork.

"Brother Kun, are you sure it's poisonous gas inside?" Ah Lian foamed at the mouth.

Fortunately, I didn't make any mistakes, otherwise the consequences would be unimaginable.

"Sure, that sign on the door means poison gas.

Cao Teniang's little Japan, who actually helped poison gas here, must have some big conspiracy. ”

"So what do we do now?" Ah Lian asked.

"Don't worry about it, find the vault and weapons depot first, and blow it up when you retreat, so that these dogs can taste the poison gas."

"Good!"

"That's right! Poison these brutes. ”

"After that incident, the priority now is to find the gold.

I think there must be more devils than this floor, and there must be a second underground floor below.

Let's take a look at it later, and look carefully at each room to see if there is a secret door or something.

Don't act rashly when you find out,"

"Understood."

"Don't worry, I'll notify you as soon as I find it."

Then, the four of them separated again and looked at each other one by one according to the route just now.

Unfortunately, after the meeting, no other entrance was found.

Liu Kun lay on the ground, frowning and thinking.

It stands to reason that there shouldn't be no passages, right? Could it be that the devil hid the vault?

Suddenly!

He remembered something.

Vaults and weapons depots don't need air, and even if you take something, you won't suffocate people inside, so naturally you don't need to make ventilation channels.

"Trouble, the devil must have put those things in a room without an passage, and if you want to take those things away, you have to risk sneaking in."

"What then? Just give up? Ah Lian asked.

Xuan Qingzi and Sima Jun also stared at Liu Kun's face, for fear that if the other party really gave up, those brothers would die in vain.

"Impossible! Even if Lao Tzu can't get those things, it's impossible to give up, it's a big deal that Lao Tzu blew up here directly. Liu Kun gritted his teeth and replied.

Thinking of the tragic death of so many brothers, how could he just retreat away in disgrace, not revenge, and swear not to be a man!

"Brother Kun, why don't we get in. I see that the devils are basically sleeping, and there are not too many people on duty.

When the time comes, go down to get some grenades at the door where the devils sleep, if they are discovered, the devils will be blown up as soon as they go out, and we are not worried that there are too many devils. ”

When Liu Kun heard it, Sima Jun's idea was good.

Besides, there is no other way but to venture in.

Moreover, Liu Kun has prepared for the worst.

If it is discovered by the devils, it is a big deal not to have gold nuclear weapons, and then it will be more direct to find a way to blow up the gas chamber.

The four of them decided to infiltrate and began researching the project.

At the first stop, they had to go to the gas chambers, get a dozen mortar shells to hang up, and cut the rope when it was time to retreat.

Because there was no one in the room in the gas chamber, Liu Kun quickly dropped the mortar shell at the vent, and then let Sima Jun pull him back to the intersection at the other end.

In order to prevent accidents, Liu Kun decided to let Sima Jun stay.

But Sima Jun disagreed, there were originally few people coming in, and if he didn't get together, his combat effectiveness would not just reduce one person.

"I didn't consult you, I ordered you to stay. In case, I mean, if we are surrounded by devils and can't get out, you blow up the things for Lao Tzu, and then run away and find a way to leave with the other brothers.

Do you understand! ”

"But ......"

"No, but! This is a military order! Liu Kun suppressed his voice and scolded angrily, then waved his hand and crawled towards the back.

Xuan Qingzi smiled at Sima Jun, patted the other party's shoulder and followed Ah Lian, and fell behind to crawl.

The captain's words just now are very clear, if they can't get out, they will die with the devil.

Sima Jun looked at the back of the distant and saluted.

I hope that the three of them will return safely.

After climbing a few forks, they came to a house where miscellaneous food was kept.

There is a devil watching in this room, and a devil is sleeping.

Liu Kun sneered, took out the long-lost crossbow from the system backpack, pressed the crossbow arrow, climbed forward, and aimed at the guard's head.

"Collapse!"

The crossbow arrow flew out, and an arrow pierced through the back of the devil's head and shot out of the mouth.

Liu Kun immediately pressed the second crossbow arrow, and the next second when the devil's corpse fell to the ground, an arrow killed the guy sleeping on the bed.

"Ah Lian stays behind, and Xuan Qingzi will go down with me."

Ah Lian immediately tightened the rope and let Liu Kun go down quickly.

Then she leaned over and let Xuan Qingzi climb down as well.

"You look at the door, I'll take the food away."

Xuan Qingzi nodded, and immediately took out a scorpion-style pistol and pointed it at the door.

And Liu Kun began to grab food non-stop, and then sent it to the system backpack in an instant.

Soon, all the supplies in the house were looted by Liu Kun.

These rations, they can eat for several years.

After finishing this room, Liu Kun took Ah Lian down, and then went over and quietly opened the door a crack.

Outside is a corridor, and there are no devils standing guard, but there seems to be footsteps, and it is estimated that they are patrolling.

After closing the door, Liu Kun whispered: "Let's take advantage of the devils patrolling over in a while, drag them in and kill them, and then pretend to be a patrol." Remember, don't make too much noise, the nearby room is the devil's bedroom. ”

"Don't worry, a few devils are fine." Xuan Qingzi replied, put the gun away, and pulled out two knives from his waist, one in each hand.

The length of the right hand and the short of the left hand.

Ah Lian also put away her gun and drew her sword, lowered the devil's military hat, and listened to the sound.

It didn't take long for the sound of footsteps to become clear, the sound of the devil's boots stepping on the ground, walking towards this direction.

Liu Kun made a gesture of preparation, and then gently opened the door a little crack, and the three of them held their breath.

When the footsteps of the devil were close at hand, Liu Kun suddenly opened the door, and Xuan Qingzi and Ah Lian rushed out in an instant.

The first devil would have thought that there was an enemy, and he saw the two commanders in front of him suddenly run out, and then he felt a cold neck and could no longer make a sound.

After Xuan Qingzi killed the first one, Ah Lian followed closely and killed the second one in the same way.

At this time, the remaining two people in the back reacted, and just as they were about to shout, they were slaughtered by two "chiefs" at the same time.
