Qin Ke and Ning Qingyun stayed up all night, and tried their best to compress the time to solve the general solution of the "Yang-Mills equation" to before dawn, so that they could prepare a breakfast for Ning Zongxun and Ji Xiuyu together in the early morning.

——They currently live in their new home in Xingguang Mingyuan Community. Unlike the garden villa at Qingmu University where they have a nanny, everything has to be solved by themselves.

But when the two quietly changed their clothes and came to the first floor, they saw Ning Zongxun and Ji Xiuyu wearing aprons and working awkwardly in the kitchen.

The goal was just to make an ordinary meal of noodles, but the two academicians, who were not good at cooking, were a little busy making it. They were afraid that the noodles would turn into lakes after being cooked for a long time, and they were also afraid that the noodles would become too hard if they were not cooked for enough time. Anyway, just watch.

Ning Zongxun Ji Xiuyu's expression at this time was as if he wanted to try dozens of scientific research experiment methods and then choose the most correct method.

Qin Ke and Ning Qingyun looked at each other and smiled, feeling both a little funny and warm.

"Dad, Mom, let's help."

With the addition of Qin Ke and Ning Qingyun, the originally small kitchen became a bit crowded, but no one left. They all savored the last warm family time before departure amidst the noise and bustle.

The topic did not deliberately avoid the upcoming separation. Ji Xiuyu, like an ordinary mother, talked about some things that should be paid attention to during pregnancy, and previewed a few things for her daughter in advance.

Ning Zongxun chatted with Qin Ke about the past experiences in the academic circle and the character of those deceased masters.

Cook breakfast together, eat breakfast together, and walk in the community together. Time passes by in such a hurry.

No matter how reluctant I was to give up, the time hand still turned to 9:00 unknowingly.

In the underground parking lot, Ji Xiuyu, with red eyes, hugged her daughter tightly and refused to let go, but after taking a few deep breaths, she finally gritted her teeth, let go, and kissed Ning Qingyun on the forehead,

She couldn't say another word, she just turned around and quickly got into the car as if she was afraid of regretting it.

Ning Zongxun patted Qin Ke on the shoulder and said to his son-in-law and daughter: "We are leaving. Please take care of yourself."

His steps were much calmer and there was no sense of rush. However, when Ning Zongxun got into the car and sat next to his wife, his unconscious glance back through the car window still revealed the reluctance in his heart.

Ten tall and strong young people saluted Qin Ke and Ning Qingyun with a standard military salute, and then sat in three cars respectively.

Seeing that the car was about to start, Qin Ke gently pushed Ning Qingyun.

Ning Qingyun resisted the tears rolling in her eyes. She bit her pink lips, caught up two steps forward, handed a thick envelope through the car window, sniffed and said: "Dad, Mom..."

This is a gift from Qin Ke and I to you."

Ning Zongxun took it and forced a smile: "Okay, go back quickly and live a good life with Qin Ke. Your parents' biggest wish for you two is that you two can live happily every day."

Ning Qingyun held Qin Ke's hand, who was following him, and nodded vigorously while crying.

The car started slowly and soon left the sight.

Ning Qingyun finally couldn't help it anymore, and threw herself into Qin Ke's arms and sobbed softly. She had just gotten to know her parents who had been separated for ten years, and they were about to be separated again. How could she not let this person who had been missing since childhood

Is the girl who loves her father and mother sad?

She choked and whispered: "Qin Xiaoke, do you think our parents will be proud of us when they see our gifts?"

Qin Ke comforted and said: "Yes, definitely."

After a few seconds, Ning Qingyun suddenly raised his head and said in a pleading tone: "Qin Xiaoke, we must stay with our child from now on... and not leave him, okay?"

Qin Ke felt sour in his heart. No matter how much Ning Zongxun and Ji Xiuyu tried to make up for it, it was obvious that her childhood and even teenage years without her parents around her had left deep psychological trauma on Ning Qingyun.

Qin Ke hugged the girl in his arms tightly and said in an extremely firm voice: "Don't worry, we will definitely be able to do it."

While soothing Ning Qingyun's emotions, Qin Ke could not help but be secretly surprised when he saw as many as six cars following Ning Zongxun and his wife.

He had noticed before that the number of security personnel protecting Ning Zongxun and Ji Xiuyu was a bit abnormal. Even if it was him and Ning Qingyun, the only people who openly protected them in the country were Wei Feng and Wei Jing. Of course,

If you include all the manpower for covert protection, intelligence analysis, logistics support, etc., there are about forty or fifty people.

If calculated based on the same light and dark ratio of 1:25, the total number of people protecting Ning Zongxun and Ji Xiuyu would probably exceed 200.

And it’s still in a relatively safe country! This is too exaggerated!

Qin Ke estimated that when he and Ning Qingyun went abroad, so many people would carefully protect them.

Obviously, the security level of Ning Zongxun and Ji Xiuyu is still higher than that of them.

No wonder Ji Xiuyu once said that the couple could not easily come back to visit Ning Qingyun because it would consume a lot of manpower and material resources from the country.

Qin Ke secretly wondered, what kind of research is his father-in-law and mother-in-law doing? Is it related to the survival of the country? Otherwise, it is difficult to imagine why there is such a high security level.

…

After the car had driven away from Xingguang Mingyuan Community for a long time, Ji Xiuyu, who was crying silently, raised her head from her husband's arms and said with red eyes: "Have you seen what gift the girl gave us?"

Ning Zongxun saw that his wife had finally calmed down, and his tense heart relaxed. He wiped the tears from his eyes and said warmly: "I haven't had time to look at it yet. I'll take it apart now and take a look."

Ning Zongxun opened the envelope and saw dozens of pages of manuscript paper inside, densely filled with mathematical calculations.

It can be seen that the upright and powerful handwriting should be Qin Ke's, while the beautiful and beautiful handwriting of Juan should be Ning Qingyun's.

"Huh? This is..."

Ning Zongxun turned over the manuscript page by page, the look on his face becoming more and more shocked.

Because there was no title on the first page of the manuscript, it took him a while to understand that these manuscripts recorded the solution process of the "Yang-Mills equation".

Seeing her husband's eyes becoming more and more focused, Ji Xiuyu unconsciously sat upright. She couldn't help but curiously leaned over and lowered her head to take a closer look at the contents.

Her mathematics level was good, but it was only at the level of an ordinary university professor. It was far inferior to her husband Ning Zongxun. After reading a few pages, she couldn't keep up. She wondered: "This is...partial differential calculus"

The process of solving equations, right? But it’s not an n-s equation.”

"It's the 'Yang-Mills equation.'" When Ning Zongxun saw the seventeenth page, he also felt that it was difficult. The above lime tsunami storm flow circulation algorithm is too profound for those who are not specialized in this partial differential equation.

It is not easy to understand for any mathematics professor, let alone Ning Zongxun, who is more focused on physics.

Ning Zongxun took a deep breath, skipped the remaining part, and turned to the last page of the manuscript with slightly trembling hands. He saw that it read: "In summary, we successfully used the 'Ling Lemon Tsunami Storm Flow Circulation Algorithm'

', the general solution of the 'Yang-Mills equation' is obtained as follows: "

"fiμν≡Σij((wx＋φ)*Ω) ∫(η,ψ) dη*d(x,t)u(x,y)/dx(σ,t) gfijkajμakv..."

Ji Xiuyu couldn't understand the advanced mathematics content in it, but she could understand this passage. Her eyes slowly opened wide, and she asked in disbelief: "Girl and Qin Ke... asked for 'Yang Mier'

General solution to Sri Lanka's equation'?"

As an academician of the Academy of Sciences whose knowledge spans several liberal arts and science disciplines, Ji Xiuyu has not studied the seven major mathematical problems of the millennium, but has heard about each problem and understands the general situation, so when he saw this passage, he immediately

Understand its meaning.

Ning Zongxun also had a look of shock on his face, and murmured: "Yes... Although my mathematics level can no longer keep up with theirs, they dare to write it out and give it to us as a gift, which is proof that they

They really did it...another millennium mathematical problem, half of the mystery has been solved by them. It's amazing, it's really amazing..."

Even though he had heard many legendary stories about his daughter and son-in-law, Ning Zongxun was still surprised, happy and shocked to witness such a legend in person.

——He knew that Qin Ke and Qin Ke had already figured out the general solution, but there was still a long way to go before actually finding the general solution. Even if it took a year and a half, it wouldn't be surprising. Who would have thought of it?

Qin Ke and Ning Qingyun could complete this huge, complex and unimaginably difficult project in just half a month?

Sitting in the co-pilot was a young man who had been following Ning Zongxun and Ji Xiuyu for a long time and was responsible for security work. However, he did not understand academic matters. Seeing that the two academicians were so excited, he couldn't help but curiously asked: "Ning Zongxun."

Academician, Academician Ji, what is this 'Yang-Mills equation'? What great academic achievements have Academicians Xiao Qin and Xiao Ning made?"

"They found the general solution to the 'Yang-Mills equation'." Ning Zongxun thought for a while before replying: "The significance of this academic achievement is equivalent to pushing forward the conquest of the grand unified theory of matter by quantum field theory.

The gate to the new world."

The young man exclaimed: "Although I don't understand it, I think it must be very powerful."

Ji Xiuyu next to her was flipping through these handwritten manuscripts page by page. She soon noticed that about two-thirds were completed by Qin Ke, and her daughter only completed one-third of them, but this third was very important.

Perfectly integrated into Qin Ke's results.

Ji Xiuyu can see from this that her daughter has surpassed herself and her husband in mathematics. She can also see that her daughter has a tacit understanding with Qin Ke and has formed a good complement to Qin Ke's mathematics achievements.

Probably, this is how the two children usually get along.

"Intimacy, perfect complementation, working together..." Ji Xiuyu gently touched the handwriting on the manuscript, turned to her husband and said: "This is what they want to tell us through these manuscripts. Now I finally fully understand

I feel relieved. No one can separate them, and no fate can separate them. Because they are the most compatible and closely connected couple in the world."

Ning Zongxun put his hand on the back of his wife's hand and smiled: "Just say you are like us."

"We are already an old couple, don't be so stupid." Ji Xiuyu said a little arrogantly - obviously, Ning Qingyun's arrogance was inherited from her mother.

Ji Xiuyu looked up at the passing scenery outside the window, but in her eyes appeared the figures of Qin Ke and Ning Qingyun, holding hands and constantly moving forward.

The mother-in-law finally showed her first smile after parting ways.

"Come on, Qin Ke, girl, you must stay happy like this!"

…

With Qin Ke's comfort, Ning Qingyun quickly cheered up from the sadness of separation. After all, compared with the past ten years when she couldn't see her parents, this time they were able to get together for more than half a month, and they were able to attend such a major life event as the wedding ceremony.

It was a big surprise for Ning Qingyun to receive the blessings from her parents.

Once the wedding is over, a major event in life is completed.

Qin Kening and Qingyun originally had a honeymoon holiday, but they both believed that as long as they were together and every day was a honeymoon, there was no need to have a formal honeymoon. Unlike weddings, which are mainly for other people and society.

Fixed rituals seen in customs.

So after the two discussed it, they quickly decided on the next itinerary. They would first complete the thesis and then go see the field promotion of desert sweet potatoes.

It took the two of them two days to write a bilingual paper in Chinese and English titled "Determining the general solution of the "Yang-Mills equation" using the quadratic optimized Lime Tsunami Storm Flow Circulation Algorithm, but it was submitted to an international publication.
