The date of the envoy to Gaochang has been set, and Wang Xiang still has many things to deal with, such as the Gewu Courtyard, the Dengxian Tower, the vegetable garden outside the city, and the promise to Ning Xiang......

Knowing Ju Yiya's identity, Wang Xiang naturally wouldn't really wait for her to take the money to redeem the knife, and wanted to return the golden knife to her directly, but who knew that this Princess Gaochang was quite proud, and she insisted on paying the debt of Dengxian Tower, and after taking back the golden knife, she repeatedly told Wang Xiang not to tell the matter of the deposit knife.

After returning to the house, Steward Wang learned that Wang Xiang was made a marquis and fainted excitedly, which made everyone scramble for a while, and finally woke him up.

The house was preparing to celebrate, and Wang Xiang went to the Gewu Academy.

Seeing the stone turn into crystal clear glass, Li Chunfeng now admires Wang Xiang's five-body throw, and he finally understands why Yuan Tiangang let him stay in the Gewu Academy, which is more suitable for him than the Qin Tianjian Gewu Academy.

After such a long time of reconstruction, the Gewu Yuan is no longer the same dilapidated as it was at the beginning, the tall courtyard wall, the guards patrolling outside the door are a team of guards dispatched by Li Er from the palace, and they usually guard the Taiji Palace, and it is enough to see that Li Er attaches great importance to the Gewu Academy, after all, Li Er's business in Liuli accounts for eighty percent.

Wang Xiang deliberately controlled the production of glass, and now the major treasure stores in Chang'an City still have a few pieces of glass ornaments produced by the Gewu Academy, they don't know that these things are mass-produced with stones, for them such lifelike glass is simply a miracle existence, as the treasure of the town store is not an exaggeration, the income is naturally very considerable.

This time, Wang Xiang of Gaochang did not know how long he would be able to return, and he copied some basic arithmetic and basic physics knowledge of later generations into a small book and handed it to Li Chunfeng.

He is just an ordinary person, lazy and timid, without any ambitions, leading the Tang Dynasty to dominate the world, he asked himself if he couldn't do it and didn't want to do it, even if he sent Gao Chang to do such a thing, he would suffer from gains and losses, no wonder even Cheng Chuliang couldn't help but be angry with him.

Maybe he was not born a hero or a sage, so he would feel awe in front of Li Er, unwilling to care about gains and losses, and he would feel fear in the face of the battlefield, even inferior to nine-year-old Li Zhi.

But he asked himself to be barely a good person, seeing that the people were in distress, he couldn't help but help them, and he had a small wish in his heart, he hoped that the prosperity of the Tang Dynasty could continue forever, and not go through so many ups and downs. Huanghuang Huaxia, thousands of years of history, but in later generations it has been stormy several times, even less than a country that has risen for only a few hundred years, he hopes that with a little knowledge he knows, he can make Huaxia less bumpy and less wind and rain, this is what he, an ordinary person, can do for the Tang Dynasty, Daxing reform, fighting and fighting is really not suitable for him.

"Daochang Li, my judgment in this academy is really unqualified, everything depends on you to do, this is some of the basic knowledge of arithmetic and Gewu that I have recorded, I hope you can do a good job in Gewuyuan."

In Li Chunfeng's eyes, this is not a basic knowledge, and he still remembers what Yuan Tiangang said: "This person may be able to start a new school." In his opinion, this small book recorded the essence of the new school, and Wang Xiang was able to hand it over to him without reservation, which was a great trust in him.

The more casual Wang Xiang behaved, the more Li Chunfeng admired and thanked him in his heart.

"Don't worry, I will definitely carry forward the study of things."

Wang Xiang shook his head, pointed to the students of the Gewu Academy who were studying not far away, and said: "It doesn't matter if you can carry it forward or not, you just need to remember that they are the hope of the future of the Tang Dynasty, not those scholars and officials who have read the books of sages and sages in the court." ”

Li Chunfeng looked at Wang Xiang inexplicably, although he also thought that Gewuxue was very powerful, but if it was more important than the study of sages, he would not dare to agree.

Wang Xiang could also guess Li Chunfeng's thoughts, and said: "Since ancient times, officials must read the book of sages, what is a sage? The Way of Confucius and Mencius. The study of the sages has been passed down for a long time, that is, the dynasty of the sages still cannot escape the fate of changing the dynasty, do you know why? ”

Li Chunfeng had never considered this question, and when he heard Wang Xiang's question, he frowned and said, "After all, sages are not omnipotent. ”

Wang Xiang laughed: "Yes, the sages are not omnipotent, because the sages can't increase grain production, can't make the people worry-free, the people can't eat enough to cover their bodies, how stable the society is, how long the country lasts!" Even if the doctrine of the sages is in full swing, the hungry people will eventually explode. ”

Li Chunfeng opened his mouth and had the heart to speak for the sage, but he didn't know how to argue.

Wang Xiang smiled slightly: "I know what you want to say, the study of sages teaches people to recognize etiquette, know good and evil, distinguish between right and wrong, and the merit of education is in the future, so they are sages." These are all true, but what the people really care about is whether they have food to eat when they are hungry, whether they have clothes to wear when the weather is cold, and the sages can't give them these things. ”

"Could it be that physics can give the people food, clothing, and clothing?"

"What do you say?" Wang Xiang asked with a smile.

Li Chunfeng was silent for a moment, the potato, the Quyuan plow, and the windmill that the Gewu Academy was studying recently at the suggestion of Wang Xiang all proved that Gewuxue could do things that the sages could not do, and these things had real benefits for the people.

"You should say these things to Your Majesty."

"Your Majesty is a king."

Li Chunfeng didn't speak, the topic was a little heavy, Wang Xiang laughed and said: "You don't have to think too much, just remember that what the Gewu Academy does is for the benefit of the country and the people, don't forget to recruit more good students for the Gewu Academy." ”

Wang Xiang left, Li Chunfeng stood in place and was silent for a long time, Wang Xiang's rhetoric can be described as deviant, but it is impossible to refute.

Sighing, Li Chunfeng recorded what Wang Xiang said today, maybe his teacher Yuan Tiangang could solve his doubts.

Heaven gives auspiciousness, 30 stones of grain per mu, this news spread quickly throughout Chang'an City and the Tang Dynasty with the end of Li Er's birthday banquet, and His Majesty ordered a big drink for five days, and the world was shaken.

The news that Wang Xiang was awarded the title of Marquis of Jiayuan also spread to Yicui Building.

Just after performing a stage play, Xiaoyun, Qing'er, and Xiaobei were all sitting and resting in Ning Xiang's room, Xiao Bei held his chin and asked Ning Xiang with a curious face: "Sister, is it true that you said that the grain that yields thirty stones per mu is true?" ”

Ning Xiang was also shocked when she first heard the news, and later heard that Xiangrui's name was Potato, so she thought of the scene when Li Shimin personally boarded the boat to see Wang Xiang on the Jinguang Lake Painting Boat in the past.

"It should be true, I heard that His Majesty personally affirmed that this auspicious rui was offered by the prince."

Xiaobei pouted and said, "If Xiangrui had appeared earlier, A-Niang wouldn't have sold me." ”

Ning Xiang touched Xiaobei's head lovingly and comforted: "Didn't Wang Gongzi promise that you would help you find your mother." ”

"Wang Gongzi was named Marquis of Jiayuan by His Majesty, will he still remember us?" Xiaobei asked with some concern.

"Yes."

Ning Xiang smiled knowingly, I don't know why, she has an inexplicable trust in Wang Xiang.
