"You say Li Changqing?", Tian Guangwen glared.

"Hmm!", Li Bingren nodded.

"Yesterday, one of my junior disciples also recommended Li Changqing to me, saying that he just used a new method to prove Fermat's theorem, I looked at the proof process he sent, it is indeed much more optimized than Wiles, and it is also a breakthrough in the field of algebraic number theory, but after all, the project of the Institute of Physics is too confidential, and I can casually pull a person outside the system into the project!"

Tian Guangwen heard that Li Bingren also recommended Li Changqing, and his heart was greatly moved, but he still had his own concerns.

"Do you think that the last time Li Changqing proved Goldbach's conjecture, the organization didn't do anything? Don't worry, Li Changqing's identity is innocent!

Li Bingren has been in the leadership position for a long time and knows more than Tian Guangwen, and although he has only had brief contact with Li Changqing, he has a deep impression of Li Changqing.

"I'm relieved to have your words, I'll fly to Wen'an this afternoon, and if I can't invite Li Changqing, I won't come back there!"

Tian Guangwen's doubts disappeared, his heart was full of pride, and he had a resolute expression.

Li Changqing only has two classes a week at Wen'an Academy, both of which have already been completed, and there will be no classes until next week.

Reading in the mountains, planting vegetables, weeding, and going around the chicken coop, the days are more leisurely.

After Zhang Jiaye drank the Sun and Moon Tonic Yuan Soup that Li Changqing gave her, she was covered in fever and sweating, but after taking a bath, she was in a lot of energy, and her skin like white paper had a trace of blood.

"Jiaye, how do you feel?"

Leukemia is also a stubborn disease in modern medicine, and Li Hongdou was also very curious about whether the medicine prescribed by Li Changqing had any effect, so he took Zhang Jiaye's hand and asked with concern.

"It's very comfortable, much more comfortable than before!", Zhang Jiaye's little face showed a sunny smile.

"I stayed in the city hospital for more than half a year and didn't get better, Mr. Li can have such an effect with a pair of medicines! If it hadn't happened to Jiajia's identity, I would definitely think it was a lie!"

Zhang Mingliang smiled honestly, a hanging heart finally let go, and he was extremely grateful to Li Changqing in his heart.

In the afternoon, Tian Guangwen flew directly to Wen'an City, and he didn't have time to communicate with Ding Shaoyuan, and only after getting off the airport did he take out his mobile phone to call Ding Shaoyuan.

"Hey, Shaoyuan, I've already arrived in your Wen'an City, and I'm planning to take a taxi to your Wen'an College to talk to Mr. Li Changqing to see if he can join our project team, you can help me arrange it!"

"Senior brother, it's too unfortunate for you to come! Mr. Li Changqing only has two classes a week, and on Tuesdays, Thursdays, and today's Friday, he doesn't have classes! Moreover, I only heard that Mr. Li Changqing lives in the mountains of Guyang County, and I don't know exactly where he is, but our Principal Qiu once went to the mountains to invite Mr. Li Changqing, if you are in a hurry to visit, I can help you talk to Principal Qiu and let him take you!"

Ding Shaoyuan knows this senior brother of his very well, if he was not forced to a certain extent by the project, he would definitely not have come all the way to Wen'an City, a small city that is not considered a third or fourth tier, to invite Li Changqing out of the mountain.

"Okay, I'm done, senior brother, I'll invite you to dinner!"

Tian Guangwen hung up the phone, thinking that the dean of the Department of Mathematics and the deputy director of the Institute of Mathematics at Mizuki University actually wanted to go to the ravine to ask someone to go out of the mountain to help solve the problems in the mathematics project, and he couldn't help but shake his head.

Ding Shaoyuan and Qiu Lexian roughly explained the situation, Qiu Lexian readily agreed, although he is the principal of Wen'an College, but compared with Tian Guangwen, the dean of the Department of Mathematics of Shuimu University and the deputy director of the Institute of Mathematics, the identity is very different, and he drove directly to Li Jiaao with Tian Guangwen.

"Director Tian, I can only lead the way for you as a driver, as for whether Mr. Li Changqing will meet you, I can't say! But you are from the Institute of Mathematics, and you are responsible for the country, and Mr. Li still has great hope of seeing you!"

Qiu Lexian recalled the scene when he invited Li Changqing out of the mountain, first clarified his own factors, and then took a picture of Tian Guangwen's ass without a trace.

"Thank you, if it doesn't work once, it's twice, if it doesn't work twice, it's three times, if it doesn't work three times, it's four times, there's always a chance!"

At the beginning, Li Changqing rejected the Hua Luogeng Mathematics Award, Tian Guangwen felt that the probability of Li Changqing going out of the mountain because of his own was very small, but he had a sincere heart and wanted Li Changqing to see his sincerity.

When I arrived at Lingxia Township, at the entrance of Lijiaao, there was a stone tablet erected four or five miles away, on which the words 'Changqing Road' were written.

"Changqing Road? Could it be that this road was built with Mr. Li Changqing's funds?" Tian Guangwen was a little puzzled.

Later, Mr. Li Changqing helped a large-scale pharmaceutical company in Guyang County solve a technical problem, and the pharmaceutical company funded the construction of this road!"

Qiu Lexian did his homework to invite Li Changqing out of the mountain and explained to Tian Guangwen.

"Mr. Li Changqing still understands medicine?", Tian Guangwen was surprised.

"Mr. Li Changqing is a doctor himself, and his medical skills are quite clever, and some incurable diseases that cannot be cured in major hospitals can be cured by medicine to him!"

"And his math?"

"Hehe, last time I came to invite Mr. Li out of the mountain, I asked curiously, and Mr. Li casually replied with two words: interest!"

"...... of interest"

Interested in mathematics and then proving the Goldbach conjecture?

Interested in mathematics and then proposing a new method of proof of optimization to Fermat's theorem?

What about those of us who have spent our entire lives studying mathematics without any major breakthroughs?

The corners of Tian Guangwen's mouth twitched, his face was blue and white for a while, and he was ashamed of himself, and he also refreshed his understanding of Li Changqing.

"Dean Tian, if you knew that Mr. Li was not only proficient in mathematics, but also had very deep attainments in medicine, Chinese studies, and calligraphy, you wouldn't think so!"

Qiu Lexian saw through Tian Guangwen's thoughts at a glance and said out.

"Chinese culture, calligraphy?", Tian Guangwen was stunned when he heard it.

"Yes, every morning people who rush to Lijiaao from all over the world to listen to Mr. Li's lecture on Chinese culture can't be stuffed, and the most popular calligraphy on the market in Wen'an City is also from Mr. Li's handwriting!", Qiu Lexian explained.

"Is this still human? It's a complete demon!"

Tian Guangwen didn't have the idea of comparing with Li Changqing for a moment, and felt that Li Changqing's love of mathematics was just out of love to prove Goldbach's conjecture and it was normal to use a new optimization method to reprove Fermat's theorem.
