Xia Hongsheng realized that this was an opportunity to make Datang a gathering place for science and technology. Although it is very backward at the moment, and it is far from the level of science and technology, it can lay a good foundation.

Just like in World War II and the war in Europe in later generations, and the United States could not burn the United States because of its separation from the ocean, the war could not burn the United States, so the United States imperialism took the opportunity to introduce many policies that were very attractive to those scientists, and most of the scientists who were suffering from the war in Europe were attracted to the United States. With the influx of a large number of scientists to the United States to escape the war, the United States has obtained a large number of scientific research results and a large number of scientific and technological personnel, thus laying the foundation of its technological superpower.

Now, the Holy See is harshly persecuting those scholars, and the Tang Dynasty can use the westward caravan to spread the support of the Tang Dynasty for the research of these scholars, so that those scholars know that the Tang Dynasty is a paradise for research and learning, where no one will persecute them, valuable research will be supported and reused, and there is a special code to protect their research results. In this way, scholars will be attracted to come to Datang, communicate with Datang scholars, and contribute to the development of Datang's science.

What a great opportunity!

Xia Hongsheng walked back and forth a few steps, then stopped suddenly, and shouted outside the door: "Qi Yong, prepare the car!" ”

But before Qi Yong could respond, he first heard a voice outside: "Senior brother, where are you going to prepare the car?" ”

With the voice, I saw Xu Qixian walk in from outside, and said, "I just saw that Hu man hurriedly go out, but the westbound caravan is back?" Did you bring back any novelty? ”

"Yes, I brought back a few Great Qin people." Xia Hongsheng nodded and said, "It is said that he is a scholar who was persecuted by the Holy See...... Forget it, you don't understand it. What to eat at noon? ”

"Masturbation!" Xu Qixian said: "But I haven't eaten it for a long time." However, there are two more things to tell you. ”

"What's the matter?" Xia Hongsheng motioned to the family next to him to go to the kitchen to talk, and sat down and asked Xu Qixian.

Xu Qixian took a sip of tea and said, "I finally got a reply, my father has agreed to enter Jingyang Academy for my brother and support your establishment of the academy." Also, Liu Shi also replied to the letter together, agreed to your invitation, and left for Chang'an in a few days. ”

"That's great!" Xia Hongsheng clapped his hands excitedly, it was really a double happiness.

Arkhand brought back scholars from the West, and Liu Shi also agreed to come to the academy to teach.

Liu Shi is a very rare talent, his real name is Liu Xin, he is very researched in Confucianism, and Confucianism in the world also has its prestige. But what Xia Hongsheng values more is not his Confucianism, but the knowledge behind his Confucianism.

Xia Hongsheng also left Luanzhou Academy, and after arriving in the capital, he learned something about Master Liu. He is the son of Liu Zhuo, one of the "two Lius" of the former Sui Dynasty.

Liu Zhuo is a very powerful person.

In addition to being a scholar who "thinks that for hundreds of years, he is erudite and incompetent", he is also an astronomer. Liu Zhuo focused on the study of "Nine Chapters of Arithmetic", "Zhou Ji", "Qiyao Almanac", etc., and also wrote "Ji Ji", "Almanac", proposed a new method, compiled the "Huang Ji Calendar", considered the unevenness of the sun's parallax motion for the first time in the calendar, and established the cubic difference interpolation method to calculate the speed of the sun and moon parallax movement, and deduced the position of the five stars and the starting time of the solar and lunar eclipses. This is a major breakthrough in the history of the Chinese calendar. In that year, Liu Zhuo was activated by Emperor Yang of Sui and appointed as a doctor of Taixue, and he found that the calendar implemented at that time was often wrong, so he suggested revisions many times. Then, he worked hard to create the "Imperial Calendar", but unfortunately because the Taishi Ling at that time did not agree with his views, the "Imperial Calendar" was not adopted. However, Liu Zhuo's research on astronomy had reached a very high level at that time. Historically, in the early Tang Dynasty, Li Chunfeng created the "Lin De Calendar", which became one of the ancient calendars, but few people know that the "Lin De Calendar" can be created, which is based on the results of the "Huangji Calendar".

It's just that although Liu Zhuo is knowledgeable, his character is not very good.

Liu Zhuo is narrow-minded and greedy for money. Seeing that his knowledge had formed a market with great potential, he immediately changed his mind and started a cultural business. Whoever does not give him a greeting gift, or who gives less of a gift, will not receive his true teachings at all. As a result, people turned from worship to disillusionment with what he had done, and began to look down on him. After his wealth turned into a lot of wealth, his court began to be cold. Because of the side effects of misconduct, Liu Zhuo was later involved in a court conflict, once again filled with "cannon fodder", and was exiled to the border to serve as an army. When he finally died, his friend Liu Xuan asked for a nickname for him, but he could not get the support of a minister. is his masterpiece "Almanac", which is an astronomical work with a high gold content, which was rejected because it contradicted the views of Zhang Xuanxuan of Taishiling. It wasn't until many years later that his scholarly views gradually became known to the world. However, due to his shortcomings in human life, his work has never been able to compare with some epoch-making things, even if it has high scientific value in itself. Liu Zhuo's talent, even if there is an incongruity with his life, but the descendants who respect knowledge still give him a fair and even extraordinary evaluation. It's a pity that thousands of years later, people only remember and talk about the "Almanac", but not Liu Zhuo.

Liu Shi is Liu Zhuo's son!

Xia Hongsheng came to Chang'an, and after knowing it, he wondered if he had inherited Liu Zhuo's mantle and inherited Liu Zhuo's research on arithmetic and astronomy. At the civil and military conference, Liu Xin led the students of Luanzhou Academy to Chang'an to participate, and Xia Hongsheng took the opportunity to ask, but he was delayed by urgent matters at that time, and left Chang'an in a hurry, and he didn't have time to invite. Then Jingyang Academy opened, Xia Hongsheng wrote to invite him to come to Jingyang Academy to teach these knowledge, and today he finally has a reply.

How can this make Xia Hongsheng unhappy?

Looking at Xia Hongsheng's overjoyed appearance, Xu Qixian pursed his lips and said, "I dare to say that you are so happy, it must not be because your brother wants to go to your Jingyang Academy to study." ”

"Of course not! I have a lot of students in Jingyang Academy. Xia Hongsheng said very naturally: "What about one more thing? What's the matter? ”

Xu Qixian rolled his eyes helplessly, and then immediately turned into a mysterious look, approached Xia Hongsheng, lowered his voice and said: "My uncle was summoned into the East Palace by the prince overnight last night, and he didn't come back until he went out for his brother. During this time, because of your affairs, my uncle has been resting at home for a long time and has not been on duty in the East Palace. Thinking about it for my brother, it may be that His Majesty wants to meet his uncle and talk about you and Hui'er, but it is not good to summon him directly, otherwise it is too obvious, and his uncle is on duty in the East Palace, so he asked the prince to summon him. If not, how can we not come back until now? (To be continued.) )
