In the polymer technology research room on the fifth floor of the Biotechnology Research Building of University A, Ren Gaoge is taking two of his students to do practical work.

Ren Gao got up suddenly, his inexplicable palpitations made him unable to meditate on the new topic at the moment, and subconsciously walked to the window, as if something was attracting his heart.

It's Monday, most of the students have classes, the campus is quiet, and even the leaves don't seem to move, which contrasts his chaotic thoughts.

I've probably been too tired lately, so I'm so upset for some reason.

It's been nearly a month since he returned home, and he's been busy, busy, even busier than when he was studying in the United States.

Although he had already decided to return to China, the research work in the United States was not completed until the end of August, and it was already September 1 when he returned to China in a hurry, so he did not have time to rest, so he devoted himself to a more busy life.

He accepted the offer from A University and brought two graduate students, which was an easy job for him. But he also fulfilled his promise to his mother - if he returned to China, he would teach at her school, which means that he is still a high school teacher, which is a bit busy. In addition, he also has a research office in the United States, and needs to communicate with his partner online. What's more, his mother arranged one blind date banquet after another for him, so except for a short sleep, he has been busy.

Moreover, he still had to find her, which was the most important thing for him at the moment, but this matter was not something that could be solved by being busy.

Finding someone is like looking for a needle in a haystack. Who would have thought that in nine years, the city would change so much.

One high-rise building after another towered so that he could no longer find her home that he once remembered. He was lucky enough to find someone who was said to be her neighbor, and the man said that her family had mysteriously disappeared eight years ago when the demolition began, and that after the high-rise was built, the family had not moved into the house, and in short, no one had seen them again.

Mysterious disappearance?!

Oh! What a weird word! Even if she gets married, shouldn't her family mysteriously disappear?!

He also contacted some of his high school classmates to find out some news about her, but only to find out the "shocking news" that he knew back then—she did not go to college and had taken a leave of absence.

Alas!

She was probably really married, but he still had to find her, not to disturb her life, he just wanted to make sure that she was doing well, did her husband treat her well, did that affect her life?

"Mentor!"

A crisp voice rang out in his ears, interrupting his thoughts abruptly. He knew that the owner of the voice came from a little girl his mother specially introduced to him - Lin Xiaoxi. She is already a senior in college and plans to go to graduate school, of course, the kind she wants him to bring.

"What's wrong?" Ren Gaoge turned around and asked, his tone gentle.

"A girl just came looking for you. Lin Xiaoxi reported.

"Yes. Ren Gaoge turned around, intending to continue to do the real yàn.

"But I told her that you were on the fifth floor, and she ran away without saying anything!"

Ren Gaoge didn't speak, and concentrated on the real yàn. For more than a month, he had become too accustomed to people coming to him, but he didn't come in directly to look for him.

Lin Xiaoxi stuck out her tongue, this kind of thing is not strange, but the girl's expression just now was different from others!
