In the materials in Wei Yuan's hands, in order to maintain the operation of the library, the administrator sold the family's house, and the family lived in the basement of the library.

It should be said that he is very conscientious as a library manager, but he is obviously an overly selfish person for his family.

For his own career, he buried the lives of his relatives.

Whoever is his family must not hate him to death. Wei Yuan thought to himself.

Wei Yuan spread out the construction drawings of the library on his lap, he compared the library in front of him with the drawings, and suddenly his eyes condensed, in this drawing, there is no basement design, only the current one-to-five-story building. That means there are only two explanations, either the basement was made afterward, or the basement existed long before that.

Wei Yuan had been using a flashlight to observe the windows of the library, and he found that the flashlight light could not shine on those windows at all, and every time it was about a hand's distance away, it was blocked back, forming a strange angle, as if there was a faint mirror barrier blocking the light.

It's like some kind of magnetic field.

During the day, these windows are normal in the sun's light, and the anomaly seems to be at the moment of nightfall.

Wei Yuan suddenly wanted to do an experiment.

He reached into his arms, and for a moment, he pulled out a small, black object.

This is Wei Yuan's research institute to improve - ultraviolet searchlight.

The biggest difference between artificial light and sunlight is ultraviolet rays and sunspots, and this flashlight simulates the ultraviolet wavelength of the sun, restoring sunlight to the greatest extent. The closest to sunlight is a solar-like flashlight.

Wei Yuan flicked the switch, and a bright white light that was different from the ordinary flashlight burst out of the black device, as bright as day, and extremely penetrating.

Sure enough, when the white light hit the glass window, it was not ejected back, and the black barrier in front of the window that blocked the light seemed to be dispelled somewhat.

However, the whole window pane was like smudged ink at this time, and his light did hit the outer layer of glass this time, but it still couldn't penetrate the black mist. This shows that the interior of the library is now impenetrable even by sunlight.

He moved the light up little by little, every layer, without any flaws.

On the dark window, there seemed to be a pair of black eyes, looking at him.

——

In the toilet, the four of them stared at each other, and finally discussed "two plans".

This toilet is the kind of old-fashioned, with latches on the back of the door, and it is still functional. So I came up with the first idea, to stay in the toilet.

"One, let's stay up all night here, maybe, after the sun comes out the next day, this library will return to normal." This is a conservative plan, but staying up all night is not sleeping all night, and it seems to be conservative but it is actually very risky.

"Second, keep searching the library, maybe you can find that so-called basement, and there may be a way to get out there." This is naturally chosen by Jiang Shan, and it is very in line with the law of not entering the tiger's den to get the tiger's son.

First of all, the entrance to this library was on the first floor, and it was common sense that they should have returned to the first floor if they wanted to leave here.

And this basement, literally, is obviously the closest place to the first floor.

Zhao Ying and Gao Wenwu have already synchronized the information, including the weird bookshelf in this library, as well as the pinyin on the painting, etc.

Zhao Ying was dumbfounded and said, "So there are two invisible black shadows outside, and it is possible that they are father and daughter??" "This can really be included in the best program of Beijing-Hong Kong Strange Talk.

"Listen, it seems to be quiet outside......" Zhang Zheng suddenly said with a little surprise.

They were discussing the most important point, and there was a quiet outside, and suddenly there was no sound.

The previous sound of the bookshelves rumbling and the books flying around disappeared all at once.

Jiang Shan and the others also noticed, and the sound of the discussion almost immediately stopped. The sudden silence made everyone a little unrefreshed.

Jiang Shan hesitated for a moment, so soon, the father taught his daughter a good lesson?

I thought it would last at least a while, but it wasn't long before they could enter the toilet that it was quiet again.

It seems that the humanoid shadow is indeed quite efficient, after all, it is a father, and he must crush his daughter in every aspect.

The headsets on everyone's chests flashed at this time, except for Zhao Ying's, which was broken, and all of a sudden, everyone else turned on automatically.

There was a burst of laughter from the headset: "Hahahaha......"

This laughter is obviously different from the previous electronic sound, with a bit of human emotions.

Zhang Zheng was the first to jump up: "I'll rely on ...... What was that? ”

For a moment, everyone was uncontrollably shocked. Even Kang Sun is the same.

"No, there is a problem, this situation is obviously ......" Gao Wenwu's face turned a little paler, he had heard this voice, "That 'daughter'?" ”

The daughter won!

What?

Looking at the flickering communication lights on his chest, and at the same time, the laughter in his ears seemed to be getting more and more unscrupulous, hahahahahahaha!

Jiang Shan was so shocked that he couldn't slow down, so this fight was lost by the humanoid shadow?

Dad lost to his daughter? Is there anything so outrageous in the world?

"Retribution for the bad guys!"

"The bad guys are really punished! Hahaha! Soon there were other words in the headset besides shrill laughter, and in addition to the harshness, this voice seemed to really have a bit of innocence.

Sure enough, Jiang Shan and Zhang Zheng also began to encounter, no matter how they turned off the headset, it would magically turn on in the next second, it really looked like someone was playing naughty pranks with them.

"What the hell is this?" Zhang Zheng clutched the communicator, "Who's laughing?" ”

Neither Jiang Shan nor Zhang Zheng had ever heard a voice other than the shadow of a human figure, and the electronic sound at a glance suddenly became kind and cute, far less eerie than the laughter in their ears now.

"Daddy is a bad guy! Daddy is a bad guy! ”

Gao Wenwu is no stranger to these words. He'd heard it all in the headset before. Combined with the speculations told by Jiang Shan, I basically know what kind of story this whole story is.

Although Zhao Ying can't hear it now, she only needs to see the expressions of her teammates, and she already has a feeling of imminent disaster.

"Who has won, you just said?" It seems that no one expected this outcome.

No matter in terms of size or identity, the humanoid shadow should not lose to the skinny daughter shadow, and it has only been a few minutes, how can the winner be determined so quickly?

Jiang Shan looked at everyone in front of him and said a little slightly. "This voice seems to be getting closer and closer."

Everyone could feel it, it was not an illusion, and the laughter and singing in their ears were slowly approaching them from far and near.
