Lu Qingyan and Lu Qingshan spent their winter vacation in Daicheng. Because grandpa, grandma, grandpa, and grandma are all in their eighties, they like to watch the younger generation gather around their knees during the Spring Festival.
Huang Yingyi is very satisfied with these two children. She is an academician and values reputation most. She has seen Lu Qingyan become a national-level young talent in mathematics and Lu Qingshan has been admitted to the highest-level physics department. What else is she dissatisfied with?
Rao Yuqiu does not care about the children's achievements and only hopes that they will have a healthy body. She was so happy when she saw Lu Qingshan getting up in the morning to practice boxing, with his fists and feet blowing like a vigorous dragon.
Rao Yuqiu is currently most concerned about her daughter's marriage.
There is a 19-year age difference between Lu Xinyuan and Lu Cheng, and they are 28 years old this year. Time passed so fast, and before he knew it, Lu Cheng was already 47 years old. If it weren't for his cultivation, he would have been a middle-aged man with a big belly.
Rao Yuqiu began to urge her daughter to get married, reminding her every day that she should find someone to marry. Seeing that Lu Xinyuan was unmoved, she started nagging Lu Cheng and Jiang Qiuyun.
"As the saying goes, an elder brother is like a father. As brothers and sisters-in-law, why don't you put some thought into helping Xin Yuan?"
Lu Cheng said: "Who said your daughter is too good and has too few choices?"
Rao Yuqiu said: "If this matter is not settled, I will nag you every day. You are also parents. Seeing Qingyan grow up, you should be able to understand my feelings, right?"
Jiang Qiuyun smiled and said: "Mom, don't worry, I have always remembered Xinyuan's marriage. I promise to marry her before she is 30, okay?" She often communicates with Lu Xinyuan, knows his general mentality, and feels that this matter Can be solved.
Rao Yuqiu sighed: "Oh, it's you and A Cheng who make us worry-free. It would be great if we settled down early."
As they grow older and improve their skills, Lu Cheng and Jiang Qiuyun's thoughts are also changing.
The 47-year-old Lu Cheng is still in peak physical condition, no different from when he was 20 years old. The condition of his wife Jiang Qiuyun is also the same. Like a girl of 17 or 18 years old, she remains youthful and her appearance remains unchanged.
Lu Cheng thought to himself: "Perhaps like in other worlds, monks can live forever in modern times? If they can live forever, what does it matter if they get married later?"
Therefore, he and his wife have agreed not to force their daughter to get married early.
If a daughter can live to be 3,000 years old, why bother having children in a hurry? The free life of immortals is also very attractive, isn't it?
During the winter vacation, Lu Qingyan was still busy.
When school was about to start, she sent her research results to her tutor Qian Wu.
Qian Wu was shocked when he saw the research results. He immediately summoned the country's top mathematicians and held an internal meeting to deduce and verify Lu Qingyan's paper.
Shortly afterwards, the paper was published in ihematicae, one of the four major journals in mathematics, which caused a huge response.
Lu Qingyan, a 20-year-old girl, has overcome one of the ten most difficult problems, the "Slipknot Problem."
In mathematics, the slipknot-dead-knot problem is the algorithmic identification of the number of unknotted knots given a certain knot.
Connecting the two ends of the rope at infinity forms a topological knot. If this knot is topologically equivalent to a cycle in some sense, it is called an unknot in mathematics, which means that the original knot is a slipknot, otherwise it is a dead knot.
Over the past 20 years, several computer algorithms have emerged that are capable of untying complex knots, but as knots become more complex, the algorithms take longer and longer. Some mathematicians believe that algorithms can eliminate any knots, while others have proven that this is impossible. They believe that the computational intensity of the "Slipknot and Dead Knot Problem" will inevitably increase, making it impossible to eliminate knots.
The news was released through CCTV and many newspapers and online media, attracting a lot of discussion and support from the public.

With the help of her thesis, Lu Qingyan graduated from graduate school ahead of schedule and became the youngest professor in the School of Mathematics at Peking University.
Some reporters tried their best to find her background, but they could not find where she was from. Even a reporter from Qilu TV searched through the household registration system of the Public Security Bureau and found an empty address. There was a house, but no one lived there.
Many netizens are curious: "Why can't we find such a big living person?"
"Call for human flesh search! Does it mean that Lu Qingyan has no classmates or friends?"
"If you can't find Lu Qingyan, you can find Lu Qingshan. It is said that these two are brother and sister."
"I'm from Suzhou. I once went to the same elementary school as Lu Qingyan. Then she transferred to another school and I don't know where she went."
"I'm from Quancheng, and I've been classmates with Lu Qingshan for a few months."
"I am Lu Qingyan's college classmate. She has been living off campus since her freshman year. We have never been to her home. I just met her and was picked up by a special car one night."
"I met her at teacher Jiang Mei's home... Teacher Jiang praised her for her amazing talent in painting..."
"I once had the honor to participate in a guqin competition with Lu Qingyan. She played the rare five-stringed qin. I don't know who she learned it from."
Suddenly, someone posted a photo: "Look, everyone, how similar is this little girl selling fruit to Lu Qingyan?"
Someone said: "Go away! This is not a person at all! This little girl has such a long scar on her face, how can she be the flawless Lu Qingyan?"
Some people also said: "What if that little girl had cosmetic surgery to repair the scar? Moreover, this little girl looks only thirteen or fourteen years old, which is six or seven years older than Lu Qingyan."
Someone directly used facial recognition software to compare and found that after removing the scars, the two pictures were 88% similar.
If the similarity exceeds 72%, the recognition is successful. But when it comes to the percentage of faces that can be compared to identify them as belonging to the same person, it’s hard to say. Therefore, the 88% similarity cannot be directly determined to be the same person.
The days fly by.
Lu Cheng still continued to travel to other worlds to practice and improve his spiritual consciousness. He travels through different worlds with his soul, not his body, so he can cultivate his soul on both sides, but he can only swallow the dragon egg liquid in modern times to strengthen his body.
Qingmei practiced with him, and her skills improved quickly. She had reached the late stage of the tenth level of spiritual witch. At the same time, she was still a spiritual warrior. After eating a small bottle of dragon egg spirit liquid, she was promoted to the middle stage of the eleventh level of spiritual warrior.
At the same time, Lu Cheng opened the supply of elixirs to Ying Chu, Si Ping and Yao Shi. In addition to dragon eggs, other elixirs could meet their requirements. Therefore, the skills of these three people also improved rapidly. Entering the late stage of spiritual warrior.
There are a total of twelve levels of spiritual warriors, and entering the ninth level is considered to be the later stage.
