And, singing?

The previous humanoid shadow never sang, and was as serious as anything.

Now this voice is not only light and lively, but also very happy.

"Lalala~ I'm coming!"

As the sound approached, the four people in the toilet were dumbfounded, "How, what to do?" ”

Jiang Shan suddenly made a gesture of silence, and then motioned for the four people to come around, if the communication channel had been intercepted, their words would probably also be transmitted to the shadow man on the other end.

Zhao Ying immediately took out a spare pen and paper from the pocket of her protective suit, and drew a big pen on it. Number.

Jiang Shan took the marker and carefully drew two circles on it.

Well? What does it mean?

Zhang Zheng looked over expressionlessly.

Immediately afterwards, Jiang Shan drew thin villains in two circles. Very simple and rough stickman.

This painting is level, and at first glance it stays in kindergarten.

Jiang Shan pointed to himself and looked at the three people opposite, as if asking for advice.

Seriously, there is no 200% tacit understanding here, and I really don't know what I'm talking about. But the three on the other side really understood, and at this time, the lively and happy voice was closer.

Approaching, as if you had already reached the door.

There's no time left for the four of them to think about anymore, no matter what three-seven-twenty-one, let's follow it first!

The voices outside the door, singing songs, came slowly......

"Is there anyone, go to the toilet...... Hee-hee-hee, I'm coming in too. Even if he was wearing a headset, Jiang Shan could intuitively feel that this voice had reached the door of the women's bathroom.

She crouched quietly in the cubicle, waiting for the "uninvited guest".

The voice seemed to be happier, "Come on, come on...... Zizizizi. "The old door of the toilet creaked open, and then there seemed to be a breeze, and there was no footsteps in the shadow, and there was no way to tell if she was approaching.

But Jiang Shan heard the door knock in the first compartment beside him.

Wow, what a familiar scene, and sure enough, it's still the kind of way of walking as expected. It's a pity that there are only three toilets in total, and there is no way to extend the process.

So Jiang Shan decided not to wait.

At the moment when he saw the door in front of him being pushed inward, Jiang Shan used all his strength and pushed it in the opposite direction!

She knew that she had indeed pushed something real, because the resistance was enormous.

When the door opened, out of the corner of her eye, she saw a figure that seemed to roll down to the corner of the toilet wall.

Jiang Shan ran as soon as she pulled her legs, she didn't love fighting at all, and her strategy was to run. Thirty-six strategies are the best policy.

The shadow that had been rushed to the base of the wall seemed to be a little "dazed", and she slowly got up, watching the nimble figure in her "eyes" rush towards the dense bookshelves of the library without looking back.

The three people in the men's toilet next door only heard the door that Jiang Shan deliberately pushed vigorously when he left, as well as the heavy sound of stomping, as if they were afraid that others would not know that she had run away.

Zhao Ying counted down ten counts in silence, and then Zhao Ying took out a pen and paper and wrote: "Now? ”

It's not a clever strategy, but it works.

Jiang Shan hid in the women's toilet alone, and when the shadow man came to the door, he deliberately made a high-profile movement to lure it away, and then waited for them to go away, and the three people hiding next to him tried to find a way to go.

Jiang Shan's deliberate slamming of the door and footsteps are signals, because the three of them can't hear the shadow man's voice, but as long as Jiang Shan's side starts running, it means that the shadow man has taken the bait.

There is a fatal flaw in this plan, that is, how to ensure that the shadow people will accurately find the "women's bathroom"?

What if the door of the men's restroom is opened? Aren't they all gone?

Several people's eyes focused on the book in Zhao Ying's hand, the childish picture drawn by Jiang Shan.

Because the shadow man - is the father and the "daughter". The daughter is female.

Shadow people retain some of their "memory patterns" as humans, and some of them are like AI programs, where their actions are stylized.

So Jiang Shancai gambled that as a thin shadow of his daughter's identity, he would follow the inherent pattern of human beings, such as going to the toilet must be a women's toilet.

The three of them heard the deafening noise next to them, and they already understood that everything was indeed developing as Jiang Shan said.

Several people exchanged glances: "Run!" ”

Gao Wenwu opened the door of the toilet and rushed out first, while Zhao Ying and Zhang Zheng, who had been holding their breath, immediately followed.

The direction in which they run is naturally the opposite of Jiang Shan, and Jiang Shan is now the target to buy them more time.

A few people didn't dare to make too much noise, saying that they were running was actually a cat tiptoeing forward, trying to shuttle forward under the cover of the bookshelf.

At the same time, the three of them held the only surviving flashlight and shone it on Zhao Ying's notepad.

Zhao Ying spread out a structural drawing of the library, and it can be seen that the structural diagram can correspond to the current five-story building one by one, including the expansion of the place has been supplemented.

Zhao Ying gestured, and then hurriedly wrote a "ground". Basement.

Gao Wenwu and Zhang Zheng stared at the pictures in their notebooks while walking quietly, and their brains were really not enough under double use. I didn't understand what Zhao Ying wanted to express.

Zhao Ying was a little anxious to use the tip of the pen to focus on the structural diagram twice.

Gao Wenwu's eyes lit up, he seemed to understand what Zhao Ying meant.

The basement mentioned by Jiang Shan.

On this diagram of the library's construction, it is clear that there is no basement. Even with the subsequent expansion, there is no indication that any construction has started underground.

Ruling out the possibility that Jiang Shan heard it wrong, after all, the three words basement were really heard by Zhang Zhengye.

The land management in Beijing and Hong Kong is quite strict, and even the owner of the library must not dig any basement without reporting for approval.

Besides, the basement can't be dug up in a day or two.

Then there is only one possibility.

This basement is a third space that existed before the library was built.

So there would be no on the original construction diagram.

"I think we should probably really find this basement." Zhao Ying suddenly whispered.

Gao Wenwu heard the sound outside the strings and frowned, "What do you say?" ”

Zhao Ying looked at the terrible darkness around her, and her voice became softer: "If this 'basement' is not in the planning plan of the library, it means that it does not belong to one of the main bodies of the library. ”

Jiang Shan said that after the restart, the library is equivalent to a completely closed space. There are no windows and there are no other exits.

It is a cohesive "inner space". (Refer to the inner world and the table world)

However, the basement is a third space that does not belong to the library itself, and perhaps there is a way out.

I've had a little irritation in my eyes lately......
