When he arrived in Yanjing, the first thing Yu Sheng'an did was naturally to visit his sister.

An Junmao forcibly entertained the two as a local snake, and set up a banquet for the two in a restaurant not far from the Forbidden City.

After meeting, An Junmao also specially explained to Yu Sheng'an: "Teacher Yu, you may think that I have nothing to do, and I am either a traitor or a thief, but what I want to tell you is that I have never thought of stealing anything from you." ”

Yu Sheng'an was a human being, of course, he understood the ridicule in her words, and replied ambiguously: "The guest is as good as the host." ”

I haven't seen her in January, Yu Xiaoqiao has lost a little weight, and her temperament is a lot more stable, but she is still very happy to see her brother, and after chatting a few words, she opened the conversation box again as before.

"Brother, do you guess I ranked first in our class?"

This is a question that the brother and sister have liked to ask each other since they were young, even if Yu Xiaoqiao later went to high school, the ranking of each test score will still be reported to Yu Sheng'an, although the answer is the same every time.

Hearing her sister ask this question, Yu Sheng'an looked at her and found that her sister's expression faintly revealed the meaning of not admitting defeat, no longer as calm as she was in high school, knowing that she was definitely no longer the first, or even the top three, so she asked seriously: "How many people are in your class?"

"32 people. ”

Yu Sheng'an thought for a while and said: "Your class is a specially approved experimental class, and all the students admitted are top students and outstanding juvenile class students, it should be said that the 32 most powerful science students in the country are in your class, so if you can enter the top 20, you will be considered the top student among the top students." ”

Yu Xiaoqiao said: "Brother, you don't have to pave so much to comfort me, I am in the top ten in our class, but the gap between everyone is not big, and it will be surpassed by the next group of people at any time, and the students in our class are not only good at exams, but also have strong hands-on ability, some can make their own drones, some are researching homemade solid rockets, and some have won the runner-up in the robot competition...... Anyway, there are all kinds of great gods, and I am far behind them in other aspects except for being a little better at exams. ”

In the end, Yu Xiaoqiao glanced at his brother with some grievances.

Yu Sheng'an smiled and said, "Xiao Qiao, let me ask you, do you understand the principles of drones, solid rockets and robots, or can you understand them?"

Yu Xiaoqiao nodded.

"Well, although I don't understand science, I know that physics is divided into two parts: theory and experiment, which complement each other and are equally important. ”

Yu Xiaoqiao smiled, nodded slightly, and didn't explain much.

Yu Sheng'an said: "Except for the students in the juvenile class, you are all champions in various places, right?"

"No," Yu Xiaoqiao shook his head, "Many of them were escorted, but they didn't take the college entrance examination." ”

Yu Sheng'an: "......" forgot that this was discussing the world of Xueba.

An Junmao, who had been silently observing the chat between the brother and sister, raised his hand and said: "I was also escorted, but I was originally escorted to study abroad, and then I stayed in the motherland because I wanted to chase stars." ”

When it came to the back, An Junmao stared at Yu Shengan unabashedly.

"Aren't you staying in the country to accomplish some big plan?" said Yu Sheng.

"That's by the way, you're the number one. ”

Yu Xiaoqiao shook his head with a helpless smile, obviously accustomed to this girlfriend's various language attacks on his brother.

Yu Sheng'an didn't think about it and said, "Come on." ”

An Junmao glanced at him, what to cheer on, so perfunctory.

After eating, the three of them walked for a while, chatting casually, An Junmao suddenly asked Yu Sheng'an: "Teacher Yu, what do you think of the parallel world?"

Yu Sheng'an's eyes lit up, turned his head to look at An Junmao, and said: "Objective existence and mutual projection, but the current science can't prove it." ”

An Junmao said, "Yes, it seems that similar code can form similar programs. ”

Yu Xiaoqiao continued: "Our exploration of the universe is too limited, and what science can't reach depends on imagination, and in the imaginary world, there must be another 'blue star', maybe on the 'other side' of the universe." ”

Yu Sheng'an said: "Then these two planets have similar historical processes, similar historical cultures, similar technological levels, and more importantly, there may be similar human beings. ”

An Junmao asked Yu Sheng'an with great interest: "Teacher Yu, if there is really another blue star in the universe, what do you think its historical process will be?"

Yu Sheng'an said: "Just take our Chinese history as an example, if there is also a country of Huaxia on the 'Blue Star 2', it may have a similar historical process as China, there are the Spring and Autumn Period and the Warring States, the Qin and Han Kingdoms, the Jin Dynasty, the Northern and Southern Dynasties, the Sui, Tang, Song, Yuan, and Ming Dynasties, but at a certain historical node, such as in the Song Dynasty, or in the Ming Dynasty, history has changed track and gone in another direction......

"In what direction?" the two girls asked together.

"I'll take the last feudal dynasty, the Ming Dynasty, as an example, if our Ming Dynasty did not have the great prince Zhu Youzhi, the peasant uprising finally succeeded, overthrowing the Ming Dynasty, and then the Ming Dynasty's general Wu Sangui, who held heavy troops to guard the Shanhaiguan, surrendered to the Qing Dynasty, led the Qing troops into the customs to defeat the peasant regime and establish a new feudal regime, then the whole historical process will be completely different......"

An Junmao said: "There will be a dynasty called 'Qing' in history. ”

Yu Sheng'an nodded.

"Interesting, so how will this Qing dynasty develop? How many years will it exist, and how will it gradually transition into the new social system?"

"According to the timeline of our world, the Qing Dynasty has existed for 276 years, and in modern times, the Western powers are still invading, but the Qing Dynasty does not have a sense of responsibility of 'the Son of Heaven guards the country, and the king dies in the community'......

Yu Xiaoqiao and An Junmao listened attentively, and when Yu Sheng'an finished speaking, An Junmao asked seriously: "Teacher Yu, can I hire you as the worldview architect in my big plan?"

Yu Sheng'an asked rhetorically: "Your big plan is to make games?"

"Let's just say that a role-playing coming-of-age game truly restores another kind of life that you fantasize in your mind, a life that may take place in a parallel world...... I'll tell you later, will you say yes or no?"

"If this stuff of my works, no problem. ”

An Junmao stretched out his little finger and said, "Pull the hook." ”

Yu Sheng'an smiled and hooked with her.

After walking for a while, An Junmao called the driver to pick up people, and the driver first sent her and Yu Xiaoqiao back to school, and then sent Yu Sheng'an back to the hotel.

Not long after returning to the hotel, I received a WeChat message from Liang Huaizhu:

"Teacher Yu, Xia Wei's agent just contacted me, she knows that you have arrived in the capital and wants to meet you, is it inconvenient for you?"

Xia Wei is a multi-faceted artist, and has made outstanding achievements in music and film and television, and won the Best Actress at the Academy Awards the year before last.

She wanted to meet herself, mostly about music.

The actress took the initiative to meet, and Liang Huaizhu specially conveyed that Yu Sheng'an of course wanted to give face, and replied: "No problem, you can make an appointment with her." ”
