There is no doubt that the password that Guo Haitao gave him just now was indeed the most difficult problem that Duan Yun encountered after becoming a master of mathematics.

This not only did not make Duan Yun feel frustrated, but it aroused his great interest.

"Teacher Guo, can I take that question away?" I want to ......," Duan Yun affirmed Guo Haitao.

"Even if you don't say it, I'll let you take this question away. Guo Haitao said to Duan Yun with a smile after hearing this.

"Hehe, that's good!" Duan Yun nodded, and then smiled and did it at the table.

"Squirrel Guiyu, hurry up and eat it while it's hot. At this time, Yang Ying walked in with a plate of braised fish.

"It looks like the color is good, who made it?" Seeing that the braised fish was bright in color and fragrant, it was appetizing, Duan Yun immediately smiled and asked Yang Ying.

"Of course, my wife did it. Yang Ying said casually.

"Master's wife is really good at cooking, whether it is knife work or heat, this fish is just right, if this is in ancient times, it is definitely the level of the imperial chef!" After Duan Yun heard this, he praised Zhao Ru repeatedly.

"Sycophant ......" After hearing Duan Yun's words, Yang Ying glanced at Duan Yun, and then said, "Master's wife cooks well and still uses it, you say?"

"I'm telling you the truth, your cooking skills are far worse, so you can learn more from your master in the future. Duan Yun pursed his lips and said to Yang Ying.

"You guy......" Yang Ying heard this, and clenched her little pink fist angrily, but because of Guo Haitao's presence, she didn't have a seizure.

"This fish is actually made by Yang Ying, I just helped to get started. At this time, Zhao Ru also walked to the restaurant with a plate of dishes and said with a smile.

"Hehe, sit down and eat quickly. Seeing that the food had been served, Guo Haitao smiled and said to Yang Ying: "Originally, I wanted you to come over for dinner today, but Yang Ying also worked hard for a long time, thank you." ”

"It's okay, Yang Ying is idle, it's ......okay to let her move" As soon as Duan Yun's words fell, Yang Ying, who was sitting next to her, stepped on under the table.

It's okay, it's right to come to Mr. Guo to help. Yang Ying said to Guo Haitao with a smile.

"What a good boy. Zhao Ru on the side heard this and praised it softly.

"Xiaoru, take out my bottle of old wine, I want to drink some today. Guo Haitao said to Zhao Ru.

"Hmm. Hearing this, Zhao Ru got up and walked into the kitchen, and after a while, took out a bottle of Lang wine.

This bottle of Langjiu looks similar to the Langjiu on the market from the packaging, but the word 'special' is printed on the side of the bottle.

This reminded Duan Yun of the bottle of special Moutai given to him by the secretary-general named Song Kun when he met Liu Linna's father before.

Backed by the state apparatus and system, these high-ranking officials are usually low-key and conservative, and they seem far inferior to the rich and celebrities in society, but they enjoy the country's top resources and supplies all the time.

People are in different positions, and their horizons and realms are also not on a parallel line, and truly successful people often don't value luxury very much, and they prefer the control and pleasure of the trader brought by the power.

Guo Haitao does not hold a public office, but he is a pillar that supports the country, and such scientific research talents are a national treasure in any country.

To use a simple analogy, Michael Jackson, a rock star who has influenced an era, has attracted the attention of the world in terms of achievements and personal wealth, but if the top scientists of any country are asked to exchange the first person in rock history, there is absolutely no country that will do this, even if a scientist is exchanged for ten MJs, no country will think that this is a good deal!

Therefore, although Guo Haitao is not rich and rich, but he is a real 'weighty' person, he is also eligible to enjoy the country's top resources, if he wants, he can also transform his knowledge into a huge amount of wealth, just a variety of patent fees, is enough for them to continue the wealth of several generations!

And compared to those huge greeds, these money are completely legal, protected by the state, and can even go down in history!

What's even more powerful is that these top national-level experts actually have a 'gold medal for avoiding death', even if they commit serious crimes in the future, the state will still try their best to preserve their lives and property, so that they can continue to serve the country, which is even a 'treatment' that many high-powered high-ranking officials do not have!

"I don't usually drink much, but I'm really happy today. Guo Haitao smiled at Duan Yun, and then said: "Although I am not a Bole, I have seen the real Maxima ...... today."

As Guo Haitao spoke, his eyes looked directly at Duan Yun.

"To be honest, Mr. Guo thinks so highly of me and invites me to be a guest here twice, and I am really flattered. As Duan Yun spoke, he hurriedly picked up the bottle of Lang wine, first filled Guo Haitao's wine cup, and then poured a glass himself, and then picked up the wine glass and said to Guo Haitao: "Teacher Guo, I really respect you very much, I respect you for this glass of wine, I will do it first, you are free!"

After Duan Yun finished speaking, he drank all the wine in the cup.

For peers, Duan Yun doesn't like to deal with older people very much, and the reason is very simple, that is, the two generations with a huge age difference basically have no common topic.

But Guo Haitao is different, Duan Yun and he both like mathematics very much, and both of them have a high level, so they have common hobbies and topics.

And Duan Yun also sincerely admires Guo Haitao's character, in fact, he is completely capable of living a luxurious life, but he can keep the dull and endure loneliness, this kind of life cultivation is impossible for Duan Yun, who has always taken pleasure in accumulating wealth.

So Duan Yun really regarded Guo Haitao as a New Year's friend!

"Okay!" Guo Haitao nodded with a smile when he saw this, and then raised the wine glass in front of him and drank it all.

After Guo Haitao put down the wine glass, Zhao Ru on the side put some food in her husband's bowl very intimately.

"Duan Yun, I want to ask you something. After a while, Guo Haitao suddenly said again.

"You say!"

"If I let you reinstate your student status, enter Huaqing University, and hire you as my assistant with a high salary, would you be willing?" Guo Haitao looked directly at Duan Yun and said.

Yang Ying, who was sitting next to Duan Yun, suddenly had eyes lit up after hearing this, a flash of excitement flashed on her face, and then she gently pulled the corner of Duan Yun's clothes with her hand.

"This ...... Is it possible?" Duan Yun frowned, and then said: "Huaqing is the top university in the country, a student like me who has been expelled, wants to return to school, and he directly enters Huaqing, I'm afraid it's impossible, right?"

"I naturally have a way to do this. Guo Haitao smiled when he heard this, and then said: "You just need to tell me if you are willing to come!"
