Ziyi wants to go to the special forces training with her, and Tang Yu wants to study medicine, so Song Yun sends Tang Yu to Si Fengnian, asking Si Fengnian to take care of Tang Yu. He doesn't need to teach him anything specifically. He will take him to help in the hospital this summer, familiarize him with the hospital environment, and learn how to communicate with patients. At the same time, he can see many different aspects of life in the hospital, which is also good for his psychological growth.

Shuting's ideal is to study mathematics and become an expert in this field.

Song Yun took Shu Ting to the research institute to find Professor Zhu, who had already established a firm foothold in the institute and had his own exclusive research project.

Professor Zhu was very surprised to see Song Yun. "Xiao Song, we haven't seen each other since I returned to China."

Song Yun smiled and said, "Yes, you are so busy, how dare I disturb you."

In fact, the two of them couldn't be said to be very familiar with each other, but Song Yun had spared no effort to save him. It can be said that without Song Yun, he would not have been able to return to China alive, let alone have the opportunity to realize his ambitions now.

He was very grateful to Song Yun.

"Come on, a busy man like you is willing to come to the institute to see me. You're definitely not here to see me."

Song Yun put down the gift she had brought and said, "I really do need your help with something."

Song Yun pulled Shu Ting over and explained her purpose.

Professor Zhu looked at Shu Ting and said to Song Yun, "I can take him, but I need to give him a test first to see if he has any talent in this area."

"Of course. If it turns out that he has no talent, I won't allow you to keep him even if you want to." Song Yun said with a smile.

Mathematics is something that requires real talent if you want to delve into it thoroughly.

Professor Zhu gave Shu Ting a set of questions based on his age, with a time limit of twenty minutes.

As a result, Shu Ting finished it in ten minutes. He wrote so quickly that he didn't even need a draft, and all the answers were correct.

Professor Zhu looked at the answers written by Qie Shuting, his eyes lit up, and he quickly asked another set of more difficult questions. Qie Shuting still answered very well. This time he used a draft and the answers were perfect.

Professor Zhu was very happy. "It's a good seedling. I'll accept it."

Shu Ting was also very happy. Not to mention anything else, the level of Professor Zhu's questions was so high that it was many times better than those of the teachers in the school.

But being suddenly in an unfamiliar environment, surrounded by strangers, was very uncomfortable for someone as reserved as Shu Ting. He said to Song Yun, "Sister, why don't you let Ziyi come too? He's better at math than me."

When Professor Zhu heard there was a more talented candidate, he was determined not to let him go. "Who is Ziyi? Such a great talent can't be wasted. Bring him here immediately."

Song Yun pondered for a moment. Ziyi wanted to join the military, but with his ability and age, there was no need for him to spend every day in the training ground. It would be nice for him to set aside some time to study here with Shuting.

It is always good to have many skills, and Ziyi does have a talent for mathematics. Last time, a mathematics expert came to Ziyi and wanted to take him as his apprentice.

"Okay, I'll go back and ask him. If he's willing to come, I'll bring him over again."

I agreed with Professor Zhu to send Shuting over tomorrow, and for the time being, I will let Shuting live in the dormitory of the institute and pay some rent, so that he can take care of his own food and accommodation.

After Song Ziyi heard Song Yun talk about Professor Zhu's deeds and that Professor Zhu's teacher was an internationally renowned mathematics genius, Song Ziyi was immediately attracted and agreed to go to the research institute with Shu Ting for a month. In August, he would go to the military for special training.

This is how the three little ones’ summer vacation life is arranged.
