The head of the bank was not worried about Jiang Bai or Yan Xiyue stealing downstairs at all.

On the one hand, the surveillance is deadly, and on the other hand, the collection cabinet will sound an alarm if someone wants to destroy it.

At this time, in the four underground floors, only Jiang Bai and Yan Xiyue remained.

"Jiang Bai, with such strict monitoring, the thousand-faced doll will definitely not be lost when it is stored here."

Yan Xiyue analyzed, "So I think it's very likely that it was transferred when it was transported up and down." ”

"Up and down?"

"I'm afraid I used to work as a waiter in an auction house, and they had to take out the real thing before they could auction it. So it's very likely that the package adjustment is in the process. ”

She explained.

"But you're talking about the bag, but now there are no fakes here."

Jiang Bai shook his head and said, "Maybe the move should be around this time, but it won't be a bag adjustment." ”

He said and looked up. There are a total of three ventilation ducts on the four basement floors. They are all about three meters above the ground, and it is difficult to reach them without tools.

In addition, the lamps here also seem to be cold lights, probably because they are afraid that the lamps that will heat up will damage the collection.

Jiang Bai walked around and looked at the other collections.

It's actually very simple in structure, and it's a warehouse to put it bluntly.

Excluding the possibility of transferring packages during the delivery process, as if the thief stole something from here, how do you leave?

And it is very likely that the thief has already cut off the power supply at this time, so it is very likely that the escape was completed in a state of gradual lack of oxygen.

"Yan Xiyue, try to see if you can reach the vent above."

Jiang Bai said, climbed up to one of the display cases, and stood up cautiously. The vents here seem to be the most accessible.

After pulling Yan Xiyue up, he held Yan Xiyue hard to look at the vent.

"Enough."

Yan Xiyue said and leaned hard into the vent, "I'll pull you." ”

Jiang Bai said, and jumped into the vent.

The inside of the pipe was pitch black, and almost nothing could be seen. You can only feel the air circulating inside.

"No, I can't go up here."

Jiang Bai found an upward passage with a flashlight on his mobile phone in front of him, but the height was a little high, and even if two people cooperated, they couldn't do it. Unless there are tools.

Therefore, Jiang Bai and Yan Xiyue could only give up this exploration of the ventilation pipe.

"Think about it, is there any other possibility?"

Jiang Bai said, "Although according to the governor, it is almost impossible to steal here, we have to really think of a way to confirm it." If you step on the point beforehand and walk through the ventilation duct, you will be able to walk without noticing. ”

"What about the upward passage just now?"

Yan Xiyue asked, "Didn't you say that this can't go up?" ”

"Neither of us can go up, but if one person has the tools, he can go up."

Jiang Bai said, "So, if you don't consider stealing during transportation, the thief should know the ventilation duct here very well, and at least have the ability to get the copper powder pipe drawing." ”

"Then how do you open the lock over here?"

Yan Xiyue asked, "If there is a power outage, it will lock ......"

"Power outage lock, that's the exit, he didn't say that these locks will be locked directly in a power outage!"

Jiang Bai speculated, "Maybe he thinks that after the power outage, the backup power will run out of air." It takes a lot of electricity to drain the air here, so how do you maintain these locks? Not to mention the first, the second and third roads all require electricity support, so as long as the first lock is broken, the thief can take it at will. ”

"Then why don't you take a little more out?"

Yan Xiyue nodded, feeling that what she said made sense, but she had a new question, "If I were this thief, I would definitely open a few more locks at this time, and then take all the things inside!" ”

There is a reason, but Jiang Bai can't explain it for the time being, and can only explain it by saying that the thief's target may only be a thousand-faced doll.

Suddenly, the lights went out!

There is some red light around it. Jiang Bai could clearly feel the ventilation pipe on his head starting to operate.

Blackout?

Jiang Bai frowned.

Some hesitation.

Do you run out for help, or stay here?

A blackout is the best chance to validate these things!

At the same time, he sensed as if someone didn't want them to leave alive.

"Jiang Bai, there's a power outage!"

Yan Xiyue ran and pressed the button of the elevator.

I saw that the button was red and it was no longer available!

"Do you have those thin hairpins?"

Jiang Bai said suddenly, "You go to the stairs to call for rescue, I still have some things to do." ”

Yan Xiyue took out a hairpin from her hair, handed it to Jiang Bai, and then ran to the stairs first.

According to the president's introduction, the stairs are straight to the first floor, but there is no way to open the door with any documents during the power outage!

Jiang Bai breathed slowly to reduce oxygen consumption, and used his "hidden" skills to unlock the lock.

In the experience of mysterious space cases, Jiang Bai actually knows a lot of ways to unlock the lock.

He had been looking at the keyhole before, just to assume that he was a thief and do these operations when the power went out.

Now that the power is out, he is just in time to be able to test.

After some unlocking, Jiang Bai successfully opened the first lock, and then he gently flicked the second lock on the lock next to him.

It's easy to push it away!

"Then the fingerprint lock should also be ......"

He muttered to himself, using his hand to open the glass cover that would have required fingerprint unlocking.

Sure enough, it's about the same as I thought.

In the event of a power outage, these locks are not protected.

The possibility remains.

Jiang Bai put things back in place and relocked the lock at the same time.

Begin to move slowly towards the stairs.

He knew he couldn't run, otherwise the oxygen would run out too quickly and he would probably not be able to get upstairs.

There were still four flights of stairs to go, Jiang Bai took one last big breath and walked into the stairwell.

Close the door, hoping that the air in the stairwell will be slower to be drained away.

When I walked up to the fourth floor, I saw Yan Xiyue knocking on the door.

At this time, Yan Xiyue was a little weak, perhaps because she consumed too much oxygen when she ran up.

Jiang Bai looked at the door, and the opaque steel door stopped them here.

"Yan Xiyue, you take it slowly."

Jiang Bai's breathing was very smooth, and there was not much hypoxia at this time.

But Yan Xiyue had already closed her eyes and was about to faint.

With such a steel door, even if you knock on the door, it will not help, you can only wait for another call or someone forcibly break down the door.

Seeing that Yan Xiyue's situation was getting worse and worse, Jiang Bai's heart was unconsciously confused.

He felt that the air was getting thinner and thinner, and if it went on like this, neither of them could hold on!

Then, Jiang Bai took a big breath.

Blow it into Yan Xiyue's mouth.

Yan Xiyue felt a puff of air coming in her mouth, and slowly regained some intuition.

When he opened his eyes, Jiang Bai was mouth-to-mouth with himself......
