I don't know if I sensed Mu Yuan's gaze or heard Mu Yuan's meaning, Grandpa Zhang smiled and asked, "Mu Yuan, you also have a crush on the old man's ears?" ”

As soon as these words came out, Wu Shengwen and Liu Yihang were stunned, what does this mean, is there any connection between the ears and checking the architectural structure of this building?

Makihara didn't explain, but had someone move over and put the ladder under a skylight. But Grandpa Zhang took out two iron plates from his pocket, these two iron plates are very ordinary, slender and long, but they are polished to shine, presumably because they are often played. I saw Grandpa Zhang sandwich these two iron plates between his fingers, his fingers trembled slightly, and the two iron plates made a crisp sound under the collision.

Seeing Grandpa Zhang's actions, Liu Yihang couldn't help but tremble, he finally understood the mystery.

"Mu Yuan, is this old brother a blind man?" Liu Yihang turned sideways and asked.

Makihara nodded.

Although Liu Yihang had already guessed this, he still felt a little incredible when he saw Mu Yuan admitting it, he sighed lightly and said: "I only heard that someone can recognize the sound and the road before, and I have always been a little suspicious, but today I finally saw it!" ”

"Shibo, you mean this is a blind man!" Wu Shengwen also felt incredible, although he had too much contact with this old man, but he had been with him for more than an hour, except for finding that this old man's movements were a little slow, he didn't find that he had the slightest blind character.

"That's what I just found!" Liu Yihang said, "When this old brother listened to it just now, I realized that his eyes were blank, and then I thought of the two iron plates, and then I understood the strangeness." ”

Just when a few people were chatting in a whisper, Grandpa Zhang's upper body had already entered the ceiling, and immediately, the impact of the iron plate sounded intermittently. Soon, Grandpa Zhang began to say the structure on the roof, where there are curves, where there are air holes, and where there are pipes, and the group in the corridor who listened to it smacked their tongues, because the security guards in this group climbed up to check, and the situation described by the old man was exactly the same as the results they had surveyed with a strong flashlight.

After repeating this several times, Grandpa Zhang had already described the structure of the entire top floor in detail from several skylights, and Mu Yuan memorized these situations one by one in his heart.

"Mr. Wu, do you have a lead plate here?" Muhara thought for a moment and asked.

"Yes!" Wu Shengwen replied.

Lead is one of the first metals used by humans, and in 3000 BC, humans smelted lead from ore. Because lead has a strong anti-corrosion, acid and alkali resistance, acid resistance environment construction, medical radiation protection, X-ray, CT room radiation protection, weighting, sound insulation and many other aspects, and is a relatively cheap radiation protection material.

Mu Yuan asked Mr. Wu to send someone to transport the lead plate directly to the top of the building, but he stood in the center of the roof and looked carefully, suddenly, Mu Yuan saw that there seemed to be a small blood stain on the ground not far from his feet, he bent down to take a closer look, and actually found a few rice and millet, Mu Yuan thought about it carefully, and couldn't help but show a smile.

After laughing, Mu Yuan walked slowly on the roof of the building. At first, everyone didn't understand what he was doing, but after a closer look, they realized that Mu Yuan was measuring the position of the top of the building. Because every time he walked a distance, he would use his toes to hit the roof of the building a few times, and the final position he drew faintly corresponded to some points downstairs in terms of number and coordinates.

In less than half an hour, some security guards panted and brought up a batch of lead plates, which were all one meter square and more than 3 centimeters thick, which was not light. Makihara had these lead plates placed on the points he had marked before, but not all of them were laid flat on the ground, but some were tiled, a little oblique, and some were even arched.

"That's it! It should be solved. Makihara clapped his hands, "Even if you can't eliminate it all, I believe the voice will be much lower!" ”

"That's it?" Wu Shengwen asked uncertainly, this is too simple, just place a few lead plates so casually, you can eliminate it?

"If Mr. Wu doesn't believe it, you can send someone down to take a look!" Makihara said.

"No, no, that's not what I meant!" Wu Shengwen hurriedly shook his hand, but he hesitated for a moment, but he still confessed his guilt and hurriedly walked towards the elevator on the roof.

"The scenery is so beautiful!" Long Ling'er stood on the edge of the building and said softly.

Overlooking the city center from a height of more than 260 meters is not something that everyone can enjoy, and Makihara knows that a certain observation deck on the South Mountain is for ticket money, and the ticket price is not low.

At this time, the lights of the city have been lit up, especially the specially arranged scene lights during the long holiday have all been turned on, distributed on both sides of the main road, flashing red, like a red dragon inhabiting the city.

"Do you like it?" Makihara gently patted Bean's head and asked.

"I like it!" Douzi stood by the wall at the top of the building, with two little hands on the wall, looking greedily at the scenery, and his eyes were like two little stars, twinkling constantly.

"It's good if you like it, if you have a chance, my brother will take you to see better scenery!" Makihara smiled.

"Hmm!" Douzi nodded, and then his eyes dimmed a little, "If only Grandpa could see it!" ”

"Hahaha!" Grandpa Zhang suddenly walked over, he smiled and said, "Grandpa has already seen it all, Douzi, study hard in the future, like your brother Muyuan, you can only see better scenery with the ability, and when you see it, come back and tell me!" ”

"Good!" Douzi nodded heavily, "In the future, I will be grandpa's eyes, and I will definitely tell grandpa the most beautiful scenery!" ”

At this moment, Wu Shengwen stumbled out of the elevator a little, with uncontrollable excitement on his face.

"It's gone, it's really gone!" Wu Shengwen shouted excitedly.

Hearing Wu Shengwen's cheers, Mu Yuan was also relieved, although he guessed the result, but he was still not sure, there was no accurate instrument to measure, and it was difficult to guarantee that there would be negligence.

"Mr. Wu, I have already roughly said the reason for this just now, let me summarize it briefly!" "Under the gravitational pull of the supermoon, the magnetic field is enhanced, which triggers a certain effect, which is strengthened by some building structures or building materials on the top floor, and then affects the hearing nerves of people, resulting in tinnitus effect," Makihara said. And I put some lead plates on the roof of this building to block or reflect these magnetic fields. If you still feel at ease, you can add some lead plates and arrange them on those points! Of course, it's okay if you don't arrange it, and when the supermoon is over, this phenomenon will disappear by itself! ”

While listening, Wu Shengwen hurriedly asked the secretary to write down Mu Yuan's words, he now admires Mu Yuan from the bottom of his heart, and his words are naturally like a holy decree.

"It's windy up there, so let's go to my office!" Wu Shengwen invited, "I'll let people make a pot of tea, and we'll talk while drinking tea!" ”

Mu Yuan consulted the opinions of the next few people, and when he saw that Long Ling'er and they all agreed, they walked to the elevator together.

"Mr. Wu, I have a question I want to ask!" When he walked to the elevator door, Makihara suddenly asked in a low voice.

"Little Brother Muyuan, please say something!"

"I just saw some blood stains and grains on the roof of the building, did you invite someone before?"

Wu Shengwen was stunned for a moment, hesitated, and still said: "Since you are a student of Shibo, some of the things I said are nothing, but please don't mention them to outsiders again!" ”

Mu Yuan nodded, he still understood these rules, he was just curious about who came before, with Wu Shengwen's identity, he must have invited a well-known person.

Seeing Mu Yuan nodding, Wu Shengwen attached himself to Mu Yuan's ear and said a person's name.
