Tang Xin wanted to run to the security department, but Dabei was too big, so she called the pay phone under the tree. The security officer who answered the phone asked for the location and the cause of the trouble, but said it was a civil servant handling official business and had reported it to the school, so it was not appropriate for them to interfere.

Tang Xin was stunned. She thought carefully about what she had seen of those men in black just now and felt that they did have bad intentions. But the security department was not coming. What should she do?

Tang Xin suddenly thought of someone. In her impression, this person had no problems that he could not solve.

The call was quickly connected, and Han Qing's annoying voice rang out from the receiver, "Who is this?"

Tang Xin quickly said, "It's me. I need your help!"

"Oh?" Han Qing's voice was filled with a hint of smile. "Tell me about it!"

Tang Xin quickly explained what she had just seen. "I think those people have bad intentions. Can you come and help Su Nian?"

"Okay, I'm at the airport now and will be there in half an hour. You wait for me at the school gate and show me the way!" Han Qing agreed without hesitation.

At this time, Su Nian, Professor Liu, Martin and several men in black had already entered the reception room.

Professor Liu was very dissatisfied: "Who are you? You barged in and arrested people without saying a word. Do you still respect the law?"

A man in black pulled out a small notebook from his pocket, opened it, and handed it to Professor Liu. "Look carefully, we have the right to investigate this student!"

Professor Liu glared and asked, "Just one document doesn't prove anything. What basis do you have to investigate her? Where's the evidence? Where are the procedures?"

The man in black was slightly embarrassed, "We just received a report!"

Professor Liu refused to agree. "Can reporting replace evidence? Then I'll report too!"

"Professor Liu, what can you report?" Yang Guangsu walked in with Chen Yuanyuan. Teacher Wu probably felt that the commotion was too much and did not appear with them.

Professor Liu was furious: "I'm going to report you! After you came to our lab this morning, I lost an important document!"

The man in black was a bit amused. Professor Liu before him was like an unreasonable child, protecting his own shortcomings and being unreasonable. "Professor Liu, Professor Yang is working with us to research a method to induce human hibernation, but not long ago, this method was used in the Mukezhai earthquake zone!"

"The person who used this method is Su Nian. To ensure the safety of Professor Yang's research, we must investigate Su Nian to see if the method she mastered originated from Professor Yang!"

Professor Liu shook his head: "Your investigation is based on inequality. We refuse to accept it!"

No matter how the man in black tried to persuade him, Professor Liu refused to agree. As a leader in a discipline, his attitude was very tough, and for a while, the two sides were in a stalemate.

Yang Guangsu looked at the time impatiently and winked at the man in black, signaling him to speed up.

Before coming, the men in black had agreed with Yang Guangsu that they would help Yang Guangsu bring Su Nian back. Now they have wasted so much time and gained nothing, and these men in black are also angry.

"Okay, since you, professor, insist on stopping us from handling the case, then come back with us!" The man in black stood up and gave orders majestically.

"I think Professor Liu is right. You have no right to take Su Nian away!" A tall figure appeared at the door of the reception room. At this critical moment, Han Qing finally arrived.
