Zhang Yuanshan called out several times before bringing Li Bing back to reality from his intoxicated state.

Zhang Yuanshan said: "Li Bing, what happened to you just now? You were so stupid that you didn't respond at all when others said hello and farewell to you, which made the repairman extremely embarrassed."

Li Bing said excitedly: "Don't worry about him for now! Brother Zhang, I already understand what the strange thing happened at Xi Mengying's house is about!"

At this time, there was another knock on the door of the room. Li Bing opened it and saw that this time it was Zhao Waner and the others who were really back. Seeing the excitement on Li Bing's face, Zhao Waner smiled and said, "Li Bing, are you sleepy?"

, there’s no need to be so happy when you see us, right?”

Li Bing chuckled and said: "Wan'er, Sister Shi, Brother Qian, you are back just in time. Come in quickly, I tell you, I already understand the reason why those strange things happened at Xi Mengying's house!" [

When everyone heard this, they became excited for a moment and hurriedly gathered around Li Bing and said, "Li Bing, tell me quickly, what is going on? The scene that day really scared us."

Li Bing chuckled and said, "Have you seen the new lights on the wall? The repairman told me all this!"

Zhang Yuanshan said in shock: "Li Bing, did you really hit something evil? I've been here too, but I didn't see the repairman say anything!"

Li Bing laughed loudly 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, you dare to laugh at Brother Qian and me? Careful, we will lift you up and throw you to the floor, causing your butt to explode."

Everyone laughed, and Li Bing said: "Wan'er, Sister Shi, you both have studied physics, do you know the phenomenon of resonance?"

Zhao Waner and Shi Liya seemed confused and could only nod their heads. Li Bing said mysteriously: "Look at the glass of water on the table. It inspired me to solve this mystery."

"A glass of water?" Zhang Yuanshan was extremely surprised: "Can a glass of water inspire you? I think you are really crazy!"

Li Bing said cheerfully: "I poured this glass of water just now. It was meant for the repairman to drink. Who knew they had regulations and they couldn't drink the water from the guests. Then the glass of water was placed on the table, and a strange phenomenon occurred.

It happened that when the repairman was drilling holes in the wall with an electric drill, the water in the cup started to shake."

Zhao Waner'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 have also seen it, right? The second phase of that community is under construction. I guess some equipment on the construction site resonated with Xi Mengying's house when it was started. This caused the house to vibrate, and the house

The things placed inside were shaken and rolled to the ground."

Shi Liya and Zhao Waner exclaimed almost at the same time: "It makes sense!" Li Bing looked even more satisfied.

Zhao Waner suddenly said: "Li Bing, even if the vibration in her room was caused by resonance with a machine on the construction site, this can be explained, but how do you explain the strange sound of footsteps in her house?"

"This?" Li Bing seemed to have been poured cold water on Zhao Waner. He was speechless for a moment and couldn't help but feel depressed.

Shi Liya looked at Li Bing's embarrassed look and said: "Li Bing, you have successfully solved the mystery of the vibration in the house. I believe you can also find the answer to the weird footsteps. We haven't encountered strange noises in the room before.

Have you been there? I remember you explaining to us the sound of rolling balls on the floor!"

Li Bing jumped up as if he was electrocuted, and said happily: "Thank you Sister Shi, I forgot about this for a moment! Yes, the footsteps of Xi Mengying's house must have a similar principle. Let me think about it, is this possible? Her house is a new house, originally a model house built in a community developed by Shen Kai. Could it be that the building materials inside have not stabilized in all aspects, and are they making sounds when various mechanical changes occur?"

Zhao Waner smiled and said: "Li Bing, since you think so, isn't it easy to know the answer?"

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

Zhao Waner 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 Guangming Company! What does Guangming Company do? Of course it is real estate development. Since it is a real estate developer , then how is it possible that there is a shortage of architectural designers and engineers? You are so stupid. If you want to verify your idea just now, call my mother and any engineer can answer your question."[

Li Bing was overjoyed and begged Zhao Waner to help him verify on the phone whether his idea had scientific basis.

Zhao Waner looked at the impatient Li Bing and laughed. She took out her mobile phone and dialed her mother Zhang Lili's number.

Zhang Lili cried with joy when she heard the greetings from her baby daughter on the phone. The mother and daughter, who had not seen each other for a long time, talked on the phone for nearly an hour before they remembered Li Bing's business.

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

Zhao Waner cheered: "The mystery is finally solved. Come on, I want to call Sister Mengying as soon as possible so that she will no longer be afraid."

Li Bing hurriedly said: "Wan'er, don't do this. This matter must be kept confidential. Don't forget, our goal is to investigate the truth of the matter after confirming that there is something wrong with Xi Mengying. And her house is haunted. This incident just gave us an excellent opportunity.”

Zhao Waner understood immediately and secretly laughed at her impulsiveness. Li Bing smiled and said: "You guys, just stay in the hotel and surf the Internet and watch TV. I'll go out to do some errands."

Zhao Waner glared and said, "Li Bing, what do you mean? We always went out together before, why do you want to sneak away alone now?"

Li Bing said mysteriously: "Wan'er, please listen to my explanation! I want to see the situation at the second-phase construction site of Xi Mengying's community. There is dust everywhere, so you should not go there. Besides, there are many people and the goal is huge. If Xi Mengying discovers us accidentally and raises alarm, we will be in trouble!"

Zhao Waner pondered for a moment, then tilted her head and asked: "Li Bing, do you want to know which piece of equipment started on that construction site and caused the resonance phenomenon in Xi Mengying's house?"
