However, to wait for "boom boom! When such a loud noise came, and after that very incredible scene happened, the bookshelf seemed to have grown legs, and suddenly it slowly slid to the right as if it could move.

And, speaking of the bookshelf, it moved, and what was revealed was the entrance behind the bookshelf, and the next moment, as if without warning, it was very strange and sudden, and countless sharp weapons were rapidly sprayed out of it.

At this time, Bai Hao, who had just turned sideways to safety, saw this scene, but only pursed his lips and smiled, and then raised his hand and touched the cold sweat that no longer existed in the corner of his forehead.

However...... Just now, Yan Xinmeng, who had already obeyed Bai Hao's instructions, and immediately jumped to the safety next to him, saw this scene, and was stunned at the same time.

It's amazing...... What a ghost! What a slot! If it weren't for Brother Bai's dexterity just now, it would have become a sieve full of holes and thousands of arrows piercing the heart, okay! Although Bai Hao, who was the last figurine, is now safe and sound, and by the way, he retreated to the side very lively, but! As long as I still think of the happy dream of the scene just now, I still feel very angry! Annoyed in her heart, she directly burst into foul language.

Then, until the bookshelf had been slid aside, and then the erupting sharp weapon was no longer continuing, it looked like it was already time to pause, at this time. The scene suddenly fell silent, so that after a while, Bai Hao made a gesture to the side of Xinmeng, and the gesture of pause was even more signaling to him, and he himself stepped forward to probe first.

However, although Xinmeng, who was already aware of the meeting, understood it in an instant, she was still very unhappy with her frowning, but she still didn't give her the spirit to make a fool of herself, so she just nodded very unhappily. I said I knew and understood.

However. Speaking of Bai Hao here, he immediately took a small step forward, picked up a book from the side, and immediately threw it towards the entrance behind the bookshelf, and then the sound sounded. "Bang! The sound fell immediately. But. But nothing strange continued to spew out. And there is nothing unusual to see. Bai Hao felt funny to himself, and seemed to feel that he was too nervous, and it was really dangerous as if this was an ancient secret room...... Thinking like this. Bai Hao shook his head amusedly, and then, Bai Hao took a slight step, and walked into the entrance behind the bookshelf.

However, Xinmeng behind him, seeing Bai Hao's back getting farther and farther away, somehow, Xinmeng's mind seemed to involuntarily remind him of the entrance that was blocked behind the bookshelf just now, without warning, very strangely, suddenly, almost ghostly, to the scene that was shot out of it with a sharp weapon......

"Brother Bai, be careful! …… Subconsciously, the dream behind him spat out without any apparentness.

Speaking of walking back in front, Bai Hao, who listened to Xinmeng's caring words suddenly, immediately turned around, but didn't say anything else, just smiled at Xinmeng, smiled warmly, and then, turned around and continued to walk forward.

And, when he walked inside, he found that there was a light source at the wall, and after Bai Hao studied it repeatedly, he felt that there was nothing unusual and turned it on directly, and then, with the illumination of the light, what Bai Hao could see was that in addition to the wall around him, there was a staircase passage leading to the bottom in front of him. After pondering for a while, Bai Hao immediately took a few steps back towards the rear, and gave the angle that Xinmeng, who had retreated outside, could see, and Bai Hao immediately gave him a gesture to "move forward".

Bai Hao and Xinmeng are absolutely tacit understanding, and Xinmeng, who has received Bai Hao's instructions here, immediately brightened up, and then without saying a word, he jumped forward briskly towards Bai Hao in front of him.

After getting off the ground in twos and threes, Xin Meng immediately kept up with Bai Hao's pace in front of him, and then the two of them decided to continue walking downward.

Entering it, seeing the staircase spreading in the countryside, Bai Hao and Xinmeng glanced at each other, and then nodded at the same time, and what was imprinted in each other's eyes was each other's determined expressions.

It was Bai Hao who walked in front, for such a staircase that stretched downward, such a deep and dark staircase, Bai Hao was searching for it with his keen sense of sense. Because, I am not sure if there are also light explosion devices and other things here, so Bai Hao does not dare to act rashly in this rash manner.

And when it comes to Xinmeng, she is also following Bai Hao's side at this moment, and at this moment, Xinmeng's delicate little face does not have the panic that the rest of the people generally say, but it is just that familiar look, eager to try a playful look.

The deeper you go, the more eerie and cold the footsteps echo below.

This staircase leading to the bottom, Bai Hao and Xinmeng also walked with gentle steps, step after step......

I don't know how long it was, the last step of the stairs was already given to Bai Hao and Xinmeng at the bottom, and the two of them immediately stopped, this is a relatively large basement. It's dark, cold, and even eerie. The room is closed, Bai Hao and Xinmeng are looking at themselves carefully at the moment, this basement seems to be some years old, and all kinds of gray layers can be seen everywhere, flying around.

After a closer look, it seems that the roof of the basement is made of precast concrete floor slabs, of course, the thickness of the slab is calculated according to the load of the first floor, and the air defense basement is calculated according to the load of the corresponding protection level......

It is well known to those in the circle that when the groundwater level is higher than the basement ground, the floor of the basement is not only subjected to the vertical loads acting on it. It also bears the buoyancy of groundwater, so it must have sufficient strength, stiffness, resistance to permeability, and the ability to resist buoyancy.

In addition, the exterior wall of the basement not only bears the vertical load of the upper part, but also bears the lateral pressure generated by the freezing of soil, groundwater and soil, so the thickness of the basement wall should be determined according to the calculation.

In addition, the doors and windows of the basement are the same as those above ground. When the window sill of the basement is lower than the outdoor ground, in order to ensure lighting and ventilation, a lighting well should be provided.

As for the light well mentioned here, it is composed of side walls, floor plates, rain shelter facilities or iron grates, and generally one for each window. When the distance of the windows is very close. Light wells can also be connected together.

Well, I said so much, but it was useless, shrugged. This is really a crooked building. Even if his Bai Hao's obsessive-compulsive disorder is turned on.

……

"Click! …… "The sound of shredded footsteps sounded in this space. It's even louder. At this moment, Bai Hao and Xinmeng were still searching and chasing in this basement.

However, after several searches. Bai Hao and Xinmeng both discovered that there was actually a dark room in the innermost part, and such a dark room, if you don't study it carefully, it is really possible to miss it. After several studies, the butt of the bricks and bricks has an obvious appearance of a gate, although it is also covered with dust, but compared to other places, it can be regarded as a little less ash.

So, with such a secret door, Bai Hao only studied it for a while, and then dismantled it in two by three. Then, Bai Hao took the opportunity to look at Xinmeng, seeing that this little girl was not only afraid but also showed a more eager expression, Bai Hao immediately shook his head with a dumb smile. Then, Bai Hao fixed the look in his eyes, and after a deep sigh, Bai Hao's slender hands suddenly gently pushed open the door.

"Squeak! Pushing open the door, Bai Hao immediately subconsciously pulled Xinmeng's slender little hands, and then took steps and walked inward steadily.

The door was slowly being pushed open, and with a gust of wind coming, Xinmeng on the side was trembling coldly, and then shivered, hiss~ A little cold? Subconsciously retreated behind him, Bai Hao on this side felt the Xinmeng girl beside him retreat backwards, and his hands immediately clenched a little tighter. Feeling the warmth transmitted from her hands, Xinmeng immediately faded her anxiety, lightened the coldness in her heart, and immediately calmed down.

Then, Xinmeng stepped into it with Bai Hao's pace, this darkroom was still dark, and the steps of the two of them were not heavy, but they were not light.

And, with this dark color, Bai Hao and Xinmeng immediately walked forward hand in hand.

"Click! …… The footsteps of the two seemed to amplify in the darkroom. It seems that in such a situation, there is an indescribable sense of gloom.

However. At this moment, the two of them didn't forget to get down to business, and while looking at the pitch-black scene in front of them, Xin Meng couldn't help but say strangely, "Huh? Brother Bai, did you say that 'Zhou Xinyu' would really be here" The words fell, and Xinmeng's eyeballs looked around with great difficulty. Hiss~~ In such an environment, is a person can actually live?

"Well, yes. Xinmeng girl, why don't we take a look at it separately first, and see if there are any bombs like photosensitive detonation devices around. Of course, if you find such a thing for unfortunate people, you must not move it, you know? When you see that kind of strange thing, don't act rashly, the general circuit trigger, a careless will cause an open circuit trigger, so that the fuse will make the bomb explode. It's definitely not going to be a joke, you know. Regarding the question delivered by Xinmeng, Bai Hao, who had a heavy face, immediately explained to Xinmeng with a very serious explanation.

And, listening to Brother Bai Zheng's words, this issue related to life events, Xin Meng was naturally sloppy, and Xin Meng immediately responded to Zhengse, "Okay, Brother Bai, I will." ＂

Immediately, the two of them also looked at it carefully. One person is in one place, but it is very tacit to inquire about it, but ......

"Bang! A voice sounded immediately, and I don't know if Xin Meng accidentally touched something, so it caused a huge noise. And Xinmeng, as a victim, couldn't help grinning with a sore foot, and then glanced at the culprit at his feet, hiss, it's a small wooden chair, damn it!

The sound that Xin Meng made immediately alarmed Bai Hao, and Bai Hao was immediately frightened to leave the research at hand and come over to look at Xin Meng. Coming to Xinmeng's side in twos and threes, Bai Hao was so frightened that he was worried, "Huh? Xinmeng girl, what's wrong, are you okay? ＂

When the words fell, Xin Meng, who was named by Bai Hao, immediately raised his eyes, and then met Bai Hao's worried pupils, Xin Meng couldn't help but smile heartily, "Brother Bai, it's okay, it's okay." I had just wandered into space when I almost kicked my chair off. At such a juncture, Xin Meng can also say jokes that entertain herself.

And Bai Hao, who was so shocked by the little ancestor that he was so coldly surprised, heard that this was the reason, and then he was so angry that he almost burst into a shudder and greeted Xin Meng's head.

The corners of Bai Hao's mouth twitched fiercely, and he smiled convulsively, just about to say something, but then, a certain voice came coldly......

"Yes, anyone? Who...... Who, in the end, yes, who, please, please, help, help me...... It's very discordant, it's weird, and when I said it slightly, the female voices who said it one after another sounded.

＂！！！ Suddenly, listening to such a voice, it suddenly sounded, and Bai Hao and Xinmeng couldn't help but feel an exclamation point in their hearts!

When she came back to her senses, Xinmeng gave Bai Hao an inquiring look, and raised her eyebrows by the way.

The latter, who would stare and watch, looked solemnly at the direction transmitted by the voice just now, although it was a pitch-black color that was difficult to detect, but he Bai Hao could still see that there was a huge table in the shape of an upside-down position, and just like that, that obstacle coincidentally blocked their vision.

Bai Hao's serious expression met Xinmeng's inquiring gaze, Bai Hao's face sank, and then he nodded firmly at Xinmeng, and then the hands that held Xinmeng involuntarily stepped up. (To be continued......)
