Li Nanzhi didn't know what they had communicated and how long they had communicated.

When he walked up to Xia Yu, he happened to hear Lao Yu whisper, "You can think about it in the future." ”

Xia Yu didn't nod or shake her head, just said "Thank you, teacher", and when she noticed his arrival, she raised her head.

Li Nanzhi, who was slightly idle, smiled at her idly: "It seems that you are very confident?" ”

"It's fine." Xia Yu said very plainly, but looking at Li Nanzhi's tone, it was also very light, it seemed that the first test was not very difficult for him.

After the test at noon, I won't know the results until tomorrow morning.

Natsuyu followed the team into the cafeteria of Momomachi University, and because they were given special care by the university, they were taken to the staff cafeteria, which only professor-level teachers could enjoy. The food here is very good, and it is no wonder that the cafeteria of Hyakomachi University has newspapers.

"Yu Jie, are you back?"

Xia Yu just took a bite of the fried chicken, and heard a shout like a bell in the distance, Xia Yu subconsciously looked up, and saw a man in his thirties walking over, dressed in a suit and leather shoes, well-dressed, showing the appearance of an elite, Lao Yu stood with him, and always felt particularly out of tune.

When Lao Yu saw him, a trace of embarrassment and worry flashed in his eyes.

"Professor Mu." He said.

"Long time no see," Professor Mu seemed excited when he saw him, "why are you back?" ”

He spoke to Lao Yu in such an intimate tone that people thought they were very good friends.

But Xia Yu's gaze swept over Professor Mu's greasy face, and he didn't think that their relationship was as good as it seemed.

The professor surnamed Mu spoke in an arrogant tone, his voice was loud, five points polite, five points ill-intentioned, the people around him constantly greeted him, and he also responded kindly, but his eyes turned to Lao Yu, but he had to bring something strange.

"Hmm... Long time no see. Lao Yu was very reluctant, but after all, he was a person he knew, and he couldn't leave in public.

"Teacher, who is he?"

"Is he your friend?"

The classmates around him began to ask about Lao Yu invariably.

"Uh......" Lao Yu didn't know how to answer.

"I see, you are the leading teacher of this year's junior high school mathematics competition, no wonder, you didn't take the doctoral exam at the beginning, it turned out that you went to middle school to become a teacher." The more frank he spoke, the more ugly Lao Yu's face became.

"Kid, I'm your teacher's friend, we've been studying here before." Professor Mu replied with a smile.

"Wow, that's amazing, are you and Lao Yu both studying mathematics?"

"Of course."

"Lao Yu is our teacher, so what are you doing?"

"I'm also a teacher," Professor Mu glanced at Lao Yu next to him with bad intentions and said, "It's just teaching here." ”

Lao Yu's face was almost green by this goods.

Xia Yu looked at Professor Mu with burning eyes, and always felt that there must be a story behind him and Lao Yu, otherwise he would not have directly mocked him in front of Lao Yu.

While speaking, Xia Yu caught a glimpse of Li Nanzhi walking over, and the other party turned his head and winked at her slyly, Xia Yu's heart trembled, and he suddenly had a bad premonition.

"Then this teacher, who is more powerful than you and Lao Yu?" Li Nanzhi said suddenly.

At this moment, the atmosphere suddenly began to freeze, and Professor Mu was stunned for a while before he saw the boy who asked him.

Li Nanzhi smiled at him, looking very innocent.
