Zhang Yuanshan called out a few times before pulling Li Bing back to reality from his intoxicated state.

Zhang Yuanshan said: "Li Bing, what happened to you just now?" Stupid, you didn't react when others greeted you and said goodbye, which made the repair master extremely embarrassed. ”

Li Bing said excitedly: "Leave him alone for now!" Brother Zhang, I already understand what happened to Xi Mengying's family! ”

At this time, there was a knock on the door of the room again, and Li Bing opened it to see that this time it was really Zhao Wan'er and they were back. Seeing the excitement on Li Bing's face, Zhao Wan'er smiled and said, "Li Bing, are you sleeping, you don't need to be happy like this when you see us, right?" ”

Li Bing grinned and said, "Wan'er, Sister Shi, Brother Qian, you came back just in time." Come in, I'll tell you, I've already understood why all those strange things happened to Xi Mengying's family! ”

When everyone heard this, they all became excited for a while, and hurriedly surrounded Li Bing and said, "Li Bing, then you can say it quickly, what is going on?" It really scared the hell out of us. ”

Li Bing smiled evilly: "You see the new lamp on the wall, right?" The repairman told me all this! ”

Zhang Yuanshan said: "Li Bing, are you really in trouble?" I've been doing it all the time, but I didn't see the repairman say anything! ”

Li Bing laughed and said: "Brother Zhang, you and Brother Qian don't understand, now you know how terrible it is to be uneducated, right?" ”

Zhang Yuanshan said happily: "Go, do you dare to laugh at me and Brother Qian?" Be careful that the two of us lift you up and throw you on the floor and make your ass blow up. ”

Everyone burst into laughter, and Li Bing said, "Wan'er, Sister Shi, both of you have studied physics and know the phenomenon of resonance, right?" ”

Zhao Wan'er and Shi Liya looked inexplicable, so they had to nod. Li Bing said mysteriously: "Look at the glass of water on the table, it is it that inspired me to solve this mystery." ”

"A glass of water?" , Zhang Yuanshan was surprised: "A glass of water can inspire you?" I think you're really evil! ”

Li Bing said happily: "I poured this glass of water just now, it was originally for the repairman to drink, but who knows that they have a rule that you can't drink the guest's water." Then the glass of water was placed on the table, and in a moment the miraculous phenomenon occurred, and the water in the cup began to shake as the repairman drilled a hole in the wall with an electric drill. ”

Zhao Wan'er's eyes flickered, and she said in surprise: "Li Bing, are you saying that the phenomenon that happened in Xi Mengying's house was caused by resonance?" ”

Li Bing nodded and said, "You also saw it, right?" The second phase of the community is under construction, and I guess it is that when the equipment on the construction site is running, it resonates with Xi Mengying's house, which causes the house to vibrate, and the things placed in the house are rolling to the ground under the vibration. ”

Shi Liya and Zhao Wan'er exclaimed almost at the same time: "Makes sense! Li Bing was even more meaningful.

Zhao Wan'er suddenly said: "Li Bing, even if the vibration in her room is due to the resonance phenomenon caused by a machine on the construction site, this can be explained, but how do you explain the strange thing about the footsteps in her house?" ”

"This?" , Li Bing seemed to be splashed with cold water by Zhao Wan'er all of a sudden, and she couldn't help but be depressed for a while.

Shi Liya looked at Li Bing's embarrassed appearance and said, "Li Bing, you have successfully solved the mystery of the vibration of the house, I believe that you will definitely be able to find the answer to that strange footsteps." Like a strange noise in the room, haven't we encountered it before? I remember you explained to us that there was a rolling marble on the floor! ”

Li Bing jumped up like an electric shock and said happily: "Thank you, Sister Shi, I forgot about this stubble for a while!" That's right, the footsteps of Xi Mengying's family must have a similar principle. Let me think about it, could this be that her house is a new house, a model house built in the community developed by Shen Kai, and it will be the sound of various mechanical changes when the building materials inside are not stable in all aspects? ”

Zhao Wan'er smiled: "Li Bing, since you think so, it's not easy to know the answer?" ”

Li Bing said in surprise: "Wan'er, do you have any good ideas?" Tell me! ”

Zhao Wan'er pretended to be disdainful and said, "Li Bing, have you forgotten your current identity?" But don't forget, you are also an employee of our bright company! What does Bright Company do? That's property development, of course. If you are a real estate developer, how can you lack designers and engineers in architecture? You're so stupid, you just want to get your idea verified, give my mom a call, and any engineer can answer your question. ”

Li Bing was overjoyed and begged Zhao Wan'er to help him quickly verify whether his idea had a scientific basis on the phone.

Zhao Wan'er looked at the impatient Li Bing and laughed. She took out her mobile phone and dialed her mother, Zhang Lili.

On the phone, Zhang Lili heard her baby daughter's greetings and cried with joy. The mother and daughter, who hadn't seen each other for a long time, had been cooking porridge on the phone for nearly an hour, and then they remembered Li Bing's business.

Sure enough, Li Bing's idea was confirmed by the architects of Guangming Company, and everyone became excited.

Zhao Wan'er cheered: "This mystery has finally been solved, quickly, I want to call Sister Mengying as soon as possible, so that she is no longer afraid." ”

Li Bing hurriedly said: "Wan'er, don't be like this." This matter must be kept secret, don't forget, our goal is to investigate the truth of the matter if we are sure that there is something wrong with Xi Mengying. And the fact that her house is haunted gives us a great opportunity. ”

Zhao Wan'er suddenly understood, and also secretly laughed at her impulsiveness. Li Bing smiled: "A few of you, just stay in the hotel and watch TV on the Internet, and I'll go out to do something." ”

Zhao Wan'er glared and said, "Li Bing, what do you mean?" We used to go out together, why do you want to sneak around now? ”

Li Bing said mysteriously: "Wan'er, listen to my explanation!" I wanted to take a look at the second phase of the construction site of Xi Mengying's community, where it was dusty, so you shouldn't go. Besides, there are many people and big goals, in case Xi Mengying accidentally discovers us and arouses alertness, it will be troublesome! ”

Zhao Wan'er pondered for a moment, tilted her head sideways and asked, "Li Bing, did you want to know which equipment was activated on that construction site that caused the resonance phenomenon of Xi Mengying's family?" ”

Li Bing nodded, and Zhao Wan'er said, "Li Bing, you are smart and confused!" You don't want to think that if you go to the construction site alone, others will take care of you? You can turn on whichever device you want? Also, even if you start any device that has caused the resonance of Xi Mengying's family, how can you know that this phenomenon has happened? ”
