Sun Yu's words made the people around him take a breath. After seeing Mingbo's nod, everyone's expressions became solemn.

"Is there any evidence?" Xia Lan asked.

Mingbo looked at the black hole on the second floor with his hands behind his back, "My experience is evidence. The problem must be with the instrument. It is your police's job to find real evidence. I am just providing you with directions. I hope you can assume that this evidence exists immediately."

When launching an investigation, doesn’t it mean that the earlier the investigation is started, the more clues can be collected?”

This is obvious criminal investigation thinking, and it is obvious that Mingbo was influenced by Mingyang.

Everyone looked at Sun Yu in unison. Naturally, they would not trust Mingbo's judgment. They would only listen to Sun Yu's decision.

"If there is a problem with the instrument, where is the most likely place to go wrong?" Sun Yu asked Mingbo.

This question made Mingbo very satisfied, and it was obvious that Sun Yu had believed his inference.

Akihiro said: "If it were me, I would tamper with the heating plate of the instrument to make the actual temperature much higher than the displayed temperature. In this way, cracks would appear in the instrument, and the internal and external pressure environment would cause an explosion."

Sun Yu nodded thoughtfully, and then asked: "Will this instrument work every day?"

"The last time I worked was three days ago." Akihiro said.

Sun Yu took a deep breath and looked at Song Wa, "Song Wa, try to get a drawing of the instrument to see what the heating plate looks like, and take the trace inspection people to the site to search. Meng Yuan, Ma Youran, you go

Find out about the surveillance on campus and see if you can find relevant surveillance videos."

Seeing that Sun Yu was really investigating the man-made explosion, Mingbo breathed a sigh of relief and said, "I have the drawings in my office, come with me to get them!"

Mingbo's movement of sighing in relief was simultaneously captured by several people present, except Xiang Fei, whose face turned dark.

Sun Yu nodded, "Then I'll go get it with you."

Sun Yu followed Mingbo and left, while Xia Lan stayed behind to direct the scene.

Mingbo's office is on the second floor of the office building of the School of Chemical Engineering. As the deputy dean, he has an independent office.

Walking into the office, Mingbo went to the cabinet and looked for drawings.

The layout of the office is very simple. In addition to the desk and chairs, the walls on both sides are cabinets filled with books and information.

Out of curiosity, and because he was bored waiting, Sun Yu took out his mobile phone and searched for Mingbo. He was stunned by this search.

Mingbo is 58 years old and is considered a leading figure in the chemical industry. He has a patent for a high-pressure precision metal refining instrument.

Sun Yu looked at Mingbo, who was still rummaging around, and thought to himself: Did he design the instrument that exploded?

"Found it!" Mingbo turned around and placed a stack of drawings on his desk, then opened them one by one, and finally pointed to a drawing, "This is what the heating plate looks like."

The drawings are very detailed. In addition to photos of the finished product, there are also computer drawings with many detailed parameters next to them.

After looking at the drawings, Sun Yu suddenly asked: "Did you design this instrument?"

"Yeah!" Mingbo didn't hide anything.

"It is precisely because you are familiar with this instrument that you suspect that someone has tampered with the heating plate." Sun Yu nodded thoughtfully, "You developed the first generation instrument five years ago, when you were also in the industry.

Teach at university.

The design of these things is definitely not done by you alone. A lot of the data in it should come from the team you lead, that is, your students, so..."

Sun Yu took out a cigarette and put it in his mouth, "You are doubting your student."

The room fell silent instantly. Mingbo looked at Sun Yu in disbelief. His surprised expression showed that Sun Yu's guess was correct.

Sun Yu took out another cigarette and signaled to Mingbo. Mingbo waved his hand and refused. Sun Yu took out a lighter and lit a cigarette for himself.

Snap!

The crisp sound of a lighter rang in the room, and the cigarette was lit.

Sun Yu remained silent until half of the cigarette in his mouth burned out, and Mingbo finally made a move.

I saw Akihiro slowly taking off his glasses and wiping them with a glasses cloth on the table, "If I say yes, will you think that my previous inference is subjective and then overturn my inference?"

"No!" Sun Yu smiled, "Because it was developed by you, I trust your reasoning even more. You must have gone through a lot of experiments when you designed this instrument, so you understand what factors will cause the instrument to explode.

.”

Sun Yu didn't say a word. The important reason why he trusted Mingbo was Mingbo's frankness and the decoration of the entire office. He could feel that Mingbo was a true scholar.

Mingbo sighed and put on his glasses, "Back then, I brought five graduate students to develop this instrument. I promised them that I would give them a generous reward after the instrument was successful. They just helped me calculate some data. This work

I could have asked outsiders to do it, but I only let them participate in order to gain benefits for them."

The rest is very simple. After the successful research and development, Mingbo did give them a reward, which is regarded as salary. The five graduate students successfully graduated. After entering the society, they discovered that Mingbo's patents were very profitable, so two students came back to ask for Mingbo.

money.

Later, a lawsuit was filed because of this. The evidence provided by Mingbo was sufficient. He confirmed that the five students only participated in data calculation and testing experiments. The core technology belonged to Mingbo alone. The two students lost the lawsuit.

The key issue is that the two students were dissatisfied and appealed, but naturally they lost the case.

It took two years, and the reputation of the two students in the circle was bad. People in the same industry respected Mingbo, and no one accepted these two white-eyed wolves.

Was your head caught in the door?

Sun Yu cursed in his heart. He really couldn't figure out the brain circuits of these two students. Who gave them the courage to sue their teacher? Regardless of the outcome, they would definitely not be able to survive in this industry.

Mingbo continued: "One of the students, named Guo Xian, received the highest remuneration, because he was the one who reminded me of the problem with the heating plate during the experiment. After many demonstrations, I found that if there was a problem with the heating plate, it would

A terrible pressure difference occurs and an explosion occurs.

That’s why I improved the heating plate and asked my electrical and electronics friends to help develop a precise temperature sensing device.

The importance and dangers of the heating plate are also emphasized in the instructions for use of the instrument, so in addition to weekly inspections by workers, students will also conduct simple inspections every time they use it."

Having said this, Sun Yu naturally understood what Mingbo meant.

"You mean, the only people who knew that a problem with the heating plate would lead to an explosion were you and your student. Now that he has been ruined, he wants to take revenge on you, so he tampered with the instruments in your laboratory?"
