Gu Sirui dials the laboratory according to the information in the photo. The phone rang three times and was picked up.

"Hello, this is the laboratory. Who do you want to speak to?"

Gu Sirui seldom said calmly, "Hello, is there a professor Chen in your laboratory? I want to ask him a few questions. "

There was silence on the other side. Then there was a crackle of keystrokes. After a while, the opposite put on the tone of sorry, "sorry, there is no professor named Chen in our laboratory. The only professor named Chen left a few months ago."

Gu Sirui is dumb, has he left? This is escape.

After thinking about it for a while, Gu Sirui went on to say, "well, I have a few questions to ask the experts in your laboratory, please ask Professor Wang --"

GU Sirui thought of the name he saw on the list, who is also an expert in the same laboratory and is also responsible for ergot alkaloids. "Is Professor Wang free this afternoon? I want to go to the lab and talk to him face to face. "

On the other side, there was another clatter, "Professor Wang didn't make an appointment this afternoon. You can make an appointment now. You should be a college student from a nearby school, right? Recently, many college students have come to the laboratory for practice. "

Gu Sirui took a puff at the corner of his mouth. You call me a college student with such a mature voice?? But he answered vaguely. If Professor Wang colludes with Professor Chen and shows his true identity, Professor Wang will not want to see him.

Three in the afternoon.

The driver safely took Gu Sirui to the door of the laboratory. After Gu Sirui told him to wait for him here, he entered the laboratory.

The lab smelled of disinfectant. Gu Sirui wrinkled his nose. He smelled the smell too many times in the hospital, which always reminds him of bad things. Gu Sirui follows the sign to find the front desk. He knocked on the table.

"Hello, I made an appointment with Professor Wang this afternoon. I made an appointment this morning."

The receptionist at the front desk checked the reservation record,

"OK, Professor Wang's office is in Room 403 on the left side of the fourth floor. He should be in the office now." Gu Sirui thanks and walks to the elevator.

The receptionist is not the same as the one who answered the phone in the morning. She looks at the appointment record and Gu Sirui's back. It doesn't look like a College students Is the record wrong?

Gu Sirui soon arrived at the door of 403. He took a breath and knocked on the door calmly.

The door opened in response to the sound. It was Professor Wang himself who came to open the door. He was stunned. Didn't you say it was a college student this afternoon?

Gu Sirui didn't want to say any more nonsense. He was eager to make a quick decision. So he said, "do you know Professor Chen?"

Professor Wang frowned. How could colleagues who had been together for several months not remember him? He just thought this person was a little strange and seldom walked with him.

Gu Sirui accurately captured Professor Wang's facial expression, and he had a bottom in his heart. Professor Wang must know him.

Professor Wang hesitated for a moment, "yes, but Professor Chen has left the company. What can I do for you, sir? "

Gu Sirui smiles and takes out a thin piece of paper from his arms. After a careful look, it is the last page of the investigation report. Gu Sirui spread out the paper to Professor Wang,

"did you work together on the development of ergot alkaloids not long ago?"

Professor Wang looked down at the paper and found that there was a list of all the researchers involved in the development.

"Yes, yes. Don't you know what the problem is? "

"Questions?" Gu Sirui sneered, "the problem is that Professor Chen stole the ergot alkaloids developed in the laboratory and poisoned others."

Professor Wang's body froze. "No, it's impossible. The finished products developed by our laboratory are sealed up completely

"Oh? Has Professor Wang checked it? " Gu Sirui leaned forward, giving people a great sense of oppression.

"No No Professor Wang couldn't help shrinking back.

Although Professor Chen usually does not talk to people, and his character is eccentric, he is not able to do such a thing, is he? Professor Wang murmured in his heart.

"Would you please check with Professor Wang?" Gu Sirui raised his hand and made a "please" gesture. Professor Wang quickly called to ask the scientific researchers in the laboratory to check the quantity of ergot alkaloids.

As time goes by, Gu Sirui is sitting leisurely on the reception sofa in the office, and his fingers are hitting the desk. Professor Wang really feels that every second is suffering. He was worried that the finished products of the laboratory would be lost and the reputation of the laboratory would be damaged, and he was afraid that the man in front of him would find fault with him. In his eyes, Gu Sirui is obviously not a good stubble.

Jingling ring - the harsh voice of the phone rings. Professor Wang answers the phone in a hurry. The voice of the phone, which is slightly urgent, reverberates in the whole quiet office. Even Gu Sirui can hear it clearly.

"Teach, Professor! The ergot alkaloid product in the laboratory has lost at least one kilogram!Professor Wang's heart sank. He looked up at Gu Sirui and found that there was a kind of subtle expression on the other side's face. After hanging up, Gu Sirui got up and went to Professor Wang's desk,

"Professor, I don't want to embarrass you. Now that it's over, just tell me what you know. " Gu Sirui takes out his mobile phone, turns to a picture of a nursing worker surnamed Jin and raises it in front of Professor Wang.

"Do you know this man?" Professor Wang shook his head blankly.

Gu Sirui also called out the photos of the hospital, "do you know this hospital?" Professor Wang was at a loss again.

Gu Sirui was silent. He didn't expect that this man didn't know anything. Gu Sirui put his mobile phone in his pocket,

"there is no other problem. I hope your laboratory, "Gu Sirui looked around at the certificates on the wall." next time, you can pay more attention to your reputation and don't lose your things again. "

After running the laboratory, Gu Sirui turns around and returns to the hospital. As soon as he enters the hospital office, Gu Sirui goes straight to the little doctor who helped him investigate the incident. Gu Sirui threw the information on the table and sat down on the bench. "Check this Chen."

The little doctor's heart is clear and his eyes are quick. After receiving the information, he began to investigate.

I didn't expect that there were new findings in this investigation.

Professor Chen has always been friendly with Dr. Xu in the personnel department of this hospital. Gu Sirui frowned and immediately called to send someone to follow doctor Xu,

but the result was disappointing. Professor Chen seemed to have evaporated and disappeared, and doctor Xu didn't act suspiciously.

Once again, the investigation met with a bottleneck, but Gu Sirui knew that he was getting closer to the truth.
