The school radio room is not very far from the school sports field, I rushed to the door of the radio room, and saw Cui Li standing in the radio room anxiously waiting.

"How is it, Cui Li, is Professor Wang coming?" I walked briskly into the broadcast room.

"Not yet." Cui Li shook his head.

"Did he leave the school athletic field?"

"It shouldn't be possible, even if he leaves the sports field, but this is the whole school broadcast, as long as Wang Lao is still in school, he will definitely hear it. Don't worry, let's wait, maybe Elder Wang is on his way here. Cui Li's words calmed my anxious heart a little.

I looked at my watch from time to time, and then looked up at the door, but I still didn't see Wang Lao.

"Cui Li, why don't you broadcast it again? Maybe he didn't hear it before. "I can almost feel my heart beating faster.

"Okay." Cui Li walked to the equipment of the radio station and continued the previous broadcast.

"Everyone, everyone, now broadcast an announcement, the winner of this year's school football final is the graduate team of the Department of Physics, so I specially invite Professor Wang Lao of the Department of Physics to come to present the award, please come to the school radio room after hearing the broadcast, thank you."

As time went on, my mind became more and more tangled. I kept speculating in my mind about all the possibilities, whether Mr. Wang had left school, or Mr. Wang was on his way here, or...

October 16, 2021 at 13:28 p.m

I stopped thinking about it. Suddenly, a familiar figure was slowly walking towards the broadcast room.

"Elder Wang! You're finally here! "I ran over excitedly.

"Isn't this Cheng Yin and Cui Li? What, did you two call me to the radio studio? Are you all part of the physics football team? It seems that you are not only outstanding in theoretical knowledge, but also in sports. Ahh

"Elder Wang, you don't want the two of us to joke. We didn't really ask you to give us an award, we have more important things to do. I looked nervous.

"Something important? What's wrong? Wang Lao also put away his smile.

"I, today... At... Study... Room... I really don't know how to tell Mr. Wang the news, but I can see that Mr. Wang's relationship with Professor Li is very good, maybe I should put it mildly...

"Cheng Yin, what happened? Don't bother with it, tell me quickly. Elder Wang looked at me and said.

Well, now is indeed not the time to care about this, it is better to tell Wang Lao quickly: "Wang Lao, I said, you must not be too excited, in fact, Cui Li and I went to the school's research room just now and learned that a person died there." "I didn't dare to look directly into Elder Wang's eyes.

"Who?" Elder Wang's eyes widened.

"It's... Plum... Professor. I bowed my head.

"What? No way! No way! How could it be him! It's impossible, you must have heard it wrong. Elder Wang suddenly became extremely excited. He kept banging on the floor of the broadcasting room with his cane. It makes a 'knock-knock-knock' sound.

"Elder Wang, I know that this matter will hit you hard, but this is all true, Cui Li and I have heard it." I don't have anything to say for a while.

"Elder Wang, don't get excited, what Cheng Yin said is indeed true. We just got back from the lab, and it's still full of police. Cui Li's words undoubtedly dealt another heavy blow to Wang Lao.

Wang Lao suddenly took a few steps back, and almost fell to the ground without standing firmly. Seeing this, Cui Li and I hurriedly helped up Wang Lao left and right.

"Are you telling the truth?" Wang Lao confirmed again.

Cui Li and I nodded.

"I'm fine, you help me to the seat over there." Wang Lao pointed to the table and chair in the corner of the broadcasting room.

"Okay, Elder Wang, be careful." Cui Li and I carefully helped Wang Lao to his seat.

"Elder Wang, I have something I want to ask you about." I asked, standing to the right of my seat.

"Just ask."

"Elder Wang, do you know why Professor Li asked why he went to the research room last night?"

Elder Wang's brows furrowed tightly, as if he was groping in his brain for everything about Professor Li yesterday. He suddenly thought of something, his brows relaxed, and said to me: "I originally agreed with Lao Li last night to go to the chess store to discuss the chess game, but I didn't expect the dean to temporarily find me something, and I really couldn't leave, so it was quite cold outside, so I asked Lao Li to put on my coat and go to my office to wait for me for a while." But when I finished talking to the dean, I didn't see Lao Li when I returned to the office, and I thought he was impatient and went back by himself. But how? I really don't understand how I ended up in the lab. Elder Wang sighed, a sad look on his face.

"In this way, even Elder Wang doesn't know why Professor Li is in the research room." Cui Li muttered to himself on the side.

Wait! Wang Lao's coat, it seems that my previous conjecture was not wrong. But I still can't figure out why Professor Li has a research room.

"Elder Wang, are you sure that Professor Li was wearing your coat at the time?" I confirmed.

"yes, he was wearing my coat at the time, what's wrong?" Elder Wang looked at me suspiciously.

"Elder Wang, if my guess is correct, the real target is not Professor Li." My eyes fell on Wang Lao.

"If it's not Professor Li, who is that?" Wang Lao asked.

"It's Elder Wang, you!"

"Me? How is this possible? Elder Wang asked in disbelief.

"I think it may be that because Professor Li was in your office at the time and was wearing your coat at the same time, he was mistaken for you Wang." My reasoning sounds.

"That's all my fault, Lao Li! Lao Li! Wang Lao slapped himself with his hand.

"Elder Wang, don't do this, you didn't know that such a thing would happen, please don't blame yourself." I took Elder Wang's hand.

"But Cheng Yin, if that's the case, why did Professor Li appear in the research room?" Cui Li's problem is exactly what I can't explain.

"Wait! Wait! I remember Lao Li sent me a message late yesterday. I wasn't too busy to see it. I don't know if it will be related. Wang Lao said and took out his mobile phone.

Professor Lee's message may explain all the things we can't understand.
