Nian Xi thought about it for a while, but he thought the atmosphere was good tonight.

Thank you for your hospitality.

Jiang Yuning: you're welcome.

The next Saturday, Nian Xi and Fang Qi worked overtime as usual. In the morning, Nian Xi told us about the carbon powder, and Fang Qi was depressed. "I met Professor Jiang yesterday, and I asked him about it for a long time, but I didn't pay any attention to me. How come your question is completely different."

"Is that the same? You are male, I am female, and do you have my beauty?" Nian Xi said coolly.

Fang Qi was struck speechless, so he had to say: "Duan Yang had carbon powder in his fingernails before he died. It is likely that he was killed in the laboratory he often stays in. However, I have been to his laboratory and there is no sign of carbon powder in it."

"This shows that the place has been cleaned up," Nian Xi and he exchanged their eyes. "It seems that we have to go to the forensic science department together. In short, this case can be basically determined to be someone from the same school who can enter the laboratory. It shows that he and Duan Yangping did the research together."

Fang Qi agreed. They finally identified four suspects, Yang Wenzhi, Zhao Yi, Wu Siyan, and Duan Yang's mentor, Han Zheng.

The first three are all Han Zheng's disciples. Although Zhao Yi is the only one who studies the same project as Duan Yang, the other two are also people who often stay in the laboratory.

In the morning, two people with the forensic science went to Duan Yang Yan's laboratory.

Every corner of nianxi inspected carefully, and finally found that the ground around the experimental platform was extremely clean.

She immediately asked the forensic staff to identify this piece, and soon found that there were small blood stains in the cracks of the floor.

Whether it is Duanyang's blood or not still needs to be identified.

After that, Nian Xi looked for the murder weapon in the laboratory. As far as the door was concerned, the voice of the forensic officer fan Chen said, "sorry, the police are checking. You can't go in Who are you going to deliver How old is it

Hearing his name, Nian Xi came out from under the table and saw Jiang Yuning standing at the gate. Today, he is dressed in a white coat with a blue shirt and tie inside. He is meticulous, but his hair is so messy What's going on?

What's more, it's a mess like it was when you left last night.

"He came to see me," Nian Xi walked over.

Fan Chen looked at Jiang Yuning oddly, then looked at Nian Xi, and said in a low voice, "Nian Xi, I haven't heard that you're looking for a boyfriend And he doesn't seem to speak

He is really very sorry. Nian Xi is also a police flower in the police station. Many colleagues have a good impression on her.

Nian Xi was a little discontented. Fan Chen said that he was dumb.

"He doesn't speak. He doesn't talk to other people except me," Nian Xi said, turning to Jiang Yuning and asking him, "how did you come here?"

"You said yesterday that you were too busy to have lunch. I'm afraid you are hungry again," Jiang explained with a clean wink in his eyes.

Year Xi a Leng, yesterday casually said a word, did not expect him to remember.

Think of the past and Feng Jichuan break up, but also because he did not eat, the result of Feng Jichuan sent a red envelope.

She was stunned for a while, until the temperature came from her hand. It was Jiang Yuning who put the lunch box in her hand.

Fang Qi came over and joked, "Professor Jiang, do you have mine?"

Jiang Yuning looked at his eyes, inexplicably, "you are so strange. I don't know you well. Why should I bring it to you?"
