He was so persuasive that he actually practiced extraordinary

Liang Shaoke seemed to wake up from a dream: "Ah, what's wrong?"

Liang Yuzhu said helplessly: "It's okay, I'm leaving."

"Oh, okay, you can eat at home by yourself tonight. If nothing goes wrong, I have to work overtime tonight." Liang Shaoke agreed and continued to study the materials with his head down.

Liang Yuzhu smiled helplessly, picked up the insulated box and turned to leave.

Just then, a police officer in uniform hurried into the office.

"Reporting to Captain Liang, after questioning, Liu Meng confessed that when he was injured, he touched the wound and hit a very thin object. He described it as a needle!"

As soon as he finished speaking, Liang Shaoke waved his hand: "It's useless to think about these things now. We have already locked the murder weapon."

However, when Liang Yuzhu heard this, her expression froze instantly, her steps stopped, and her whole body became as stiff as a sculpture.

Needle...the murder weapon...could it be a needle?
"Dad! Is the murder weapon really a needle?" Liang Yuzhu turned around in shock and asked.

Liang Shaoke was startled by his daughter's reaction. The police officer was also startled and nodded subconsciously.

After getting the answer, Liang Yuzhu immediately fell into deep thought.

After hearing the word "needle", a person suddenly appeared in her mind - her classmate, the young anchor Zhang Beixing who was also at school that day.

Thinking about it now, Zhang Beixing’s behavior that day was indeed a bit strange.

He said he was called by the teacher to help, but he was reading Taoist doctrines in the library, as if he was practicing.

After reading and eating, he said he had nothing to do and wanted to go back to school, then left.

It doesn't look like he was called by the teacher to help, but more like he sneaked into the school.

And, most surprising of all, the murder weapon was a needle...

What Zhang Beixing broadcast live on the live streaming platform was the art of threading wood with a flying needle.

Although my dad agreed that it was a special effect and fake at the time, think about it now, what is the difference between a needle that can go straight through the body of a human trafficker and penetrating that piece of wood?
Could it be, is it really him?
"Girl, what's wrong with you?" Liang Shaoke asked doubtfully, his eyes full of confusion.

Liang Yuzhu thought for a moment, frowned and said, "Dad, do you remember the video I showed you a few days ago? It was a video of a host flying a needle through a piece of wood."

Liang Shaoke was stunned, then nodded and said, "Remember, isn't that a special effect?"

Liang Yuzhu bit her lip tightly: "That day... I saw the anchor at school. He was my classmate, named Zhang Beixing."

Hearing this, Liang Shaoke's mouth gradually opened wider and his pupils shrank involuntarily.

He seemed to have thought of something, his eyes full of strangeness: "You mean..."

Liang Yuzhu shook her head and quickly added: "Dad, this is just my guess, I'm not sure."

"It's unlikely. After all, he was just a live streamer. Moreover, it's impossible to drive a needle through a wooden board with human strength." Liang Shaoke pondered for a while and shook his head. "And according to the current direction of the investigation, the man in the dark should be using some kind of weapon."

After saying that, he walked around the desk and said, "My girl, don't leave yet. Stay in the office. I may need your help in the afternoon."

Then he opened the office door and ran outside.

Liang Shaoke did not take the anchor Zhang Beixing mentioned by his daughter seriously, but told the investigators his daughter's idea of ​​finding him.

Soon, investigators contacted all the people who were in the school that day and narrowed down the suspects to three people in the shortest possible time.

"Li Rongfang, female, a staff member of the school library, was on leave that day, but some people said she showed up in the school and seemed afraid of being seen. She herself said that she was going to look for a male teacher that day, and she was sneaking around because she was afraid of being seen."

"Zhao Jinzhong, male, a student at the University of Traditional Chinese Medicine. He sneaked into the school without being summoned by a teacher. He said he came to check out the school, but the real reason is still unknown."

"Zhang Beixing, male, a student at the University of Traditional Chinese Medicine. He ran into Li Wenjing and Liang Yuzhu at school that day, and the three of them went into the library together and stayed there until noon. But according to inquiries to the teachers, Zhang Beixing did not receive any notification from any teacher to come to school that day. At present, we do not know the purpose of this student named Zhang Beixing going to school."

When Liang Shaoke got the final list of suspicious persons, he looked at the last student named "Zhang Beixing" on the list, and the expression on his face froze.

It’s… this Zhang Beixing again?

Liang Shaoke stared at the information, looked at the student named Zhang Beixing, and recalled what his daughter had said.

He still couldn't agree with the video his daughter watched. It was humanly impossible to make a needle pass through a wooden board.

But Zhang Beixing appeared at the scene of the crime, and appeared in the school as a suspicious person, so he is a suspect no matter how you look at it.

That video... no matter what, that video is also a direction for investigation. They can never judge whether this person is suspected of a crime based on subjective conjecture.

At this time, a burst of hurried footsteps came. "Captain Liang, the director wants you to attend a meeting."

Liang Shaoke nodded blankly, then stood up and walked towards the meeting room.

At the meeting, Li Wenshan glanced coldly at the police officers present, his expression serious and gloomy.

"Everyone, have you got any results on your investigation into Zhang Beixing?"

The police have conducted relevant investigations on Li Rongfang and Zhao Jinzhong, and have preliminarily ruled them out as suspects.

After all, one is a library worker who is obsessed with finding a lover, and the other is a student who sneaks into the school to find inspiration for his novel.

It is impossible for either of them to make such sophisticated weapons.

In this way, Zhang Beixing was the only one left among the three suspicious persons.

As long as Zhang Beixing's suspicion is eliminated, all their efforts today will be in vain.

Since there are no suspicious persons, we have to find someone new.

As he mentioned this last suspicious person, the officers' faces lifted.

"Director, according to our investigation, he is a student at the University of Traditional Chinese Medicine. His parents have been abroad for many years, and he has a younger sister at home, and he usually lives with his sister."

Li Wenshan nodded: "At present, there is nothing suspicious about Zhang Beixing."

"That's true. He looks like an ordinary student." Fu Yuheng said casually.

The meeting room was plunged into a dull atmosphere, and the air seemed to be frozen.

If Zhang Beixing is ruled out as a suspect, they may really have to look for someone new.

At this time, Liang Shaoke, who was sitting in the middle of one side of the conference table, looked at the police officers present and then at the director.

"Director, we found a video here about Zhang Beixing." Wang Chengtian, a member of the investigation team, stood up and said solemnly.

All the police officers turned their heads at the same time. Li Wenshan's eyes lit up and he quickly asked, "What video is it?"

Fu Yuheng also questioned: "If it has nothing to do with the case, try not to take it out."

Wang Chengtian shook his head: "Before I show you the video, I need to tell you something I know. This Zhang Beixing is also a host on a live broadcast platform, and the content of his live broadcast is flying needles through wood."

"Flying needle pierces wood!" Li Wenshan stood up with his eyes wide open. He seemed to have grasped something.

The rest of the police officers present, except Liang Shaoke, all looked at Wang Chengtian with a hint of surprise in their eyes.

Flying needles piercing wood... Why does it sound so similar to the man in the dark they are looking for? They are all flying needles!
Then, Wang Chengtian put forward a premise: "This anchor did not use any weapon, but relied purely on the method of swinging his hands." As soon as these words came out, all the police officers were surprised.

Li Wenshan opened his mouth wide and asked in confusion: "Hand shaking? How is this possible?"

The police officers couldn't help laughing and thought that this anchor named Zhang Beixing was incredible, with a unique train of thought and outstanding ideas.

Wang Chengtian said nothing more, walked silently to the projection device, imported the video and played it.

He explained: "This is a video of Zhang Beixing's live broadcast. In the video, he used his hand to swing a silver needle through a wooden board."

The police officers' attention was immediately drawn to the projection screen, and they watched the video intently.

In the video, a young man in his twenties, with his hands bent backwards, seemed to be pinching something. Less than five meters in front of him, hung a three-centimeter-thick wooden board.

The young man just swung his hand, and the object in his hand was instantly thrown out, turning into a stream of light, rushing towards the wooden board with the force of breaking through the air!

The next second, the wooden board shook slightly a few times, and the silver needle had already sunk deeply into the wall behind the board, and the tail end was trembling rapidly.

After the video ended, the entire conference room fell into a strange, eerie and solemn atmosphere.

No one spoke at this time.

Liang Shaoke sighed and smiled helplessly: "I have seen this video before."

Li Wenshan immediately interrupted him and asked in a low voice: "Lao Liang, do you think this video is credible?"

Liang Shaoke shook his head: "Director, my first reaction at the time was that this video was very likely a special effect." Li Wenshan nodded thoughtfully.

Wang Chengtian narrowed his eyes and said, "Captain Liang, Chief, this video has been professionally tested by our police station and no traces of special effects were found."

However, he also felt that it was indeed incredible that the silver needle could be passed through the wooden board just by swinging it with the hand.

That's what an investigation is all about, you need to find out every suspicious point.

Li Wenshan looked around the conference table and asked sharply, "What do you think of this video?"

At this time, Zhou Mingjiang stood up and said solemnly: "According to the feedback from the video, it can be confirmed that the thickness of the wooden board in the video is between two and three centimeters, and it will definitely not exceed three centimeters."

He paused, then continued, "Suppose it was a three-centimeter plank of the softest wood in the world—balsa wood..."

He gave a detailed explanation, including the hardness of the board and the force required for the silver needle to penetrate the board.

After some complicated calculations, he came to the conclusion: assuming that the young man wanted the silver needle to penetrate a three-centimeter balsa wood board, he would need to exert a force at least four times that of the board at the moment of throwing the silver needle, which is at least 1200N.

The meeting room was silent, and all the police officers were impressed by the series of calculations and complex formulas.

Knowledge can not only change one's own destiny, but now it seems that it can also change the destiny of others.

Li Wenshan asked with a strange look on his face, "So that means it's possible for the young man in the video to pierce the wood with a flying needle?"

Zhou Mingjiang nodded and shook his head: "It's possible, but not very likely."

He further explained that the wood in the video is most likely not balsa but more common planks, which are much harder.

In this case, even if the young man could exert tremendous force, the silver needle would not be able to withstand it.

The conference room fell silent again.

Although they don't quite understand what these complex calculations and data mean, they know that they are several times beyond human limits.

To be precise, no one can achieve this.

Then this video of a needle piercing through wood can only be fake or... a special effect?
Li Wenshan asked somewhat uncertainly.

Zhou Mingjiang thought for a moment and agreed: "It could be some kind of technique. It's definitely not something that can be done just by shaking your hands."

At this moment, Liang Shaoke suddenly stood up and proposed a new possibility: "Is it possible that he is the owner of that dangerous weapon? Was the flying needle piercing the wood in the video made use of that weapon?"

This sentence was like a bomb, exploding in the silent crowd.

However, Wang Chengtian shook his head and denied this possibility: "The silver needle in this video was indeed shot out from his hand, and we watched the entire video over and over again, and there is indeed no trace of suspected weapons."

As he said this, the bomb went off.

The investigation once again hit a stalemate.

Everything will start over again and all speculations will be overturned.

At this time, someone said, "Could it be a prop?"

In an instant, everyone looked up with surprise, astonishment and realization in their eyes.

If it wasn't a wooden board, but something very similar to a wooden board, like foam or something, then that would make sense.

However, although this explanation makes sense, it does not provide any substantial help in their search for the person.

The police officers found it both amusing and speechless.

Just then, hurried footsteps sounded and stopped outside the conference room door.

"Report to the Director! Commander August Tan, the commander-in-chief of the border defense forces under the Yun Province Military District of the Southern Theater, wants to communicate with you."

Everyone in the conference room was stunned, and Li Wenshan was even more confused. It was obvious that he was very surprised by all this.

They are police officers representing the public security, procuratorial and judicial organs, while August is the commander of the border guards and represents the military.

Under normal circumstances, the military and the police are inseparable, but in reality the two sides do not interfere with each other.

Except for certain specific things where they occasionally work together, it is almost impossible for them to interact with each other. (End of this chapter)
