Second underground floor.

They looked at each other and looked at the door in front of them, the combination lock.

Once this kind of combination lock is out of power, it can only be entered with the key.

But it doesn't matter to them because they neither know the password nor can they find the key.

I just searched on the first floor and couldn't find the key to the vault.

Sun Ji frowned and said:

"It seems like this should be the treasury!"

"Bing, bring the cutting machine."

A Bing and another person dragged a small cutting machine over.

Chacha!

The sharp blade of the cutting machine continued to rotate, flying sparks.

The noise was huge, echoing back and forth in the dark corridor.

It seemed that the noise had stimulated the zombies on other floors in the corridor, and several zombie roars were heard from above.

Listening to the roars of the zombies, Sun Ji felt sweat dripping from his forehead.

"Stop."

A Bing quickly stopped cutting.

Sun Ji said to several team members: "The four of you go upstairs and find a way to seal the corridor on the second floor. You have to be fast."

"Yes." Gu Feiyang nodded and hurried upstairs with the three team members.

Watching them leave, Sun Ji continued to let A Bing cut him.

Chacha!

The cutting machine cut through the steel door, but within less than a minute, the cutting machine blade cut through the door.

"Cut through?" A Bing was a little confused.

I pulled out the cutting machine blade and compared the depth of the blade embedded in the steel door. This door is only five centimeters thick.

Sun Ji was also a little surprised, "Why are you still standing there? Keep cutting. Cut it earlier. It will be over soon."

"Oh ok."

Continue cutting.

Chacha!

In less than fifteen minutes, they had cut the door open.

Looking at the door that was cut through, Sun Ji and others were a little surprised. It was too easy.

"Go in and have a look." Sun Ji no longer thought about it. As long as he could find gold and complete the task, nothing else mattered.

At this moment, there was a sudden sound from above.

Boom!

Wow!

A lot of gravel fell from their heads.

"Grass?"

Sun Ji raised his head in shock and couldn't help cursing, "Isn't Gu Feiyang's grandson using a bomb? Can bombs be used in this place?"

This is in the middle of the city, and it's underground, using bombs!

What's more, if too many bombs are used, the door might not be able to blow open, but it could bury itself instead!

"What the hell are you doing?" Sun Ji picked up the walkie-talkie and said angrily.

Gu Feiyang said with some grievance: "There were too many zombies coming down from upstairs. We couldn't stop them, so we simply blew up the corridors on the third and fourth floors and blocked the corridors with waste materials."

"You..." Sun Ji didn't know what to say for a moment.

He hung the walkie-talkie on his chest and was too lazy to talk to Gu Feiyang anymore.

He raised his steps and walked towards the cut-out door.

As soon as he came in, he was stunned.

Twenty meters ahead of them, there was another door.

And this door looks bigger and thicker,

The gate is three meters high and more than six meters long.

There is also a disk in front of the door, which looks extremely complicated.

Under the illumination of the light, it reflects a golden luster, which makes it look extremely thick at first glance.

this......

Sun Ji said to A Bing with some embarrassment: "Keep cutting, I guess there is a vault behind this door."

A Bing looked at the door, swallowed his saliva and said:

"I'm afraid this door is difficult to cut open. I've never seen such a big door before."

"This low-power cutting machine is too inefficient. It is better to use a high-power cutting machine to cut."

"Okay, you cut it first, and I'll take someone up to get it." Sun Ji left two people behind and took the other two people upstairs.

Soon, he reached the first floor.

Looking at the piles of construction waste on the second and third corridors, I murmured with lingering fear:

"Fortunately, the corridor is strong enough, otherwise this waste material could collapse the stairs on the first floor."

He ran out of the building in a hurry.

The situation outside has been controlled. Blocked by folding roadblocks and car walls, the zombies outside can't get in. Only the occasional high-jumping zombie jumps in.

But Cannon and the others came up with a new solution, which was to pull two iron ropes on both sides of the stone pillar at the door. In addition, the roadblock was more than one meter high. The two iron ropes were hung on the roadblock to stop the high-jumping zombies.

At this time, Cannon and the others are doing this.

Sun Ji ran to Li Tie's side,

"Captain, we found the vault and have opened a door. However, there is another door behind this door, which is not easy to open. Now go get a high-power cutting machine, otherwise it will not be opened."

Li Tie asked:

"Can it be cut before the sun goes down today?"

Sun Ji thought of the door and replied hesitantly:

"It's hard to say, that door looks really...but we'll try our best."

"Go ahead and hurry up." Li Tie nodded.

Sun Ji hurriedly ran to the heavy truck and called five or six people to help lift the high-power cutting machine off the truck. He also brought two buckets of water down.

When cutting, you must pour some water from time to time to cool down, otherwise the cutting machine blade will easily break due to high-speed rotation and high temperature.

There are three cutting machines on the heavy truck, one with high power, one with medium power and one with low power.

The cutting machine that Sun Ji and the others brought with them for the first time was of low power.

Now take this high-power cutting machine down. Considering the power consumption of the cutting machine, they also brought many batteries, which store nearly a thousand kilowatt hours of electricity.

After three or four trips, they moved all three cutting machines down.

The three cutting machines were carried down together with the storage batteries.

Fortunately, there was dozens of square meters of space in front of the door, enough for them to put down these things.

Sizzssssssss!

Sparks flew everywhere, and A Bing wore a protective mask and continued to cut at the alloy door.

The three cutting machines were cut separately and simultaneously, but it took half an hour to cut ten centimeters.

And it didn’t cut to the end.

A Bing was sweating profusely and put down the cutting machine with some exhaustion. "Captain, this door is harder than the door outside, and it doesn't feel the same at all."

Sun Ji frowned, pointed at another team member and said: "You are on top, the machine cannot stop when the person stops."

This chapter is not over yet, please click on the next page to continue reading! Then he looked back at A Bing and asked, "Is it possible to blow up the wall?"

"The walls of a vault of this level are made of reinforced steel plates, which are at least several meters thick. If it were to be blown up with a bomb, we would all be buried in it."

"The kind of bank vaults shown in foreign movies that are blown up by bombs are all...the ones abroad are all old banks. The provincial banks here cannot be blown open by bombs...

..”

A Bing drank two mouthfuls of water and said breathlessly:
