When Yin Qingfeng left the Eastern Palace, he was in such a good mood that he was about to explode.

Before yesterday, he had four identities: the concubine's son of Duke Yun's mansion, the brother of Duke Wu's mansion, the "owner of the mansion" of Wutong Villa and the future husband of Princess Huangchang. Now, he has another title - a few teachers.

Some teachers were named by him, and each dynasty had no official position.

The Grand Tutor is the emperor's teacher, the Shao Tutor is the prince's teacher, and so on, the Emperor's grandson's teacher is of course the Shao Tutor.

At the end of the chat last night, when Li Shimin asked him to take Li Chengqian back to the villa for teaching, Yin Qingfeng knew that not only did Li Shimin's "small misunderstanding" about him was clear, but it also contained two other deep meanings.

"If you have any misunderstandings before, you don't have to worry now. Look, I even have the future heirs to teach you personally. How do you or the immortal who taught you knowledge want to govern the Tang Dynasty? I will cooperate, and my son will cooperate after becoming the emperor. As for how he will cooperate, it depends on how you teach yourself."

It has to be said that Li Shimin's move did make Yin Qingfeng feel much more at ease.

In history, there was no shortage of bastard emperors in every dynasty, but there were very few examples of killing his teacher like Zhu Zhanji, the Emperor Xuanzong of Ming Dynasty. If Li Chengqian really killed him in the future, then Yin Qingfeng would be dead without complaints.

Li Chengqian's apprenticeship ceremony is very simple.

Yin Qingfeng sat on the chair in the hall. Li Shimin and Changsun brought Li Chengqian into the hall. Then Li Shimin saluted Yin Qingfeng and asked Yin Qingfeng to be his eldest son's teacher. After Yin Qingfeng "agreed", Li Shimin and his wife saluted Yin Qingfeng and thanked Yin Qingfeng, and then asked Li Chengqian to kneel down and kowtow to become his master. As a result, there was another teacher-student relationship between his brother-in-law and his brother-in-law.

After all, Li Chengqian was still young and didn't know the meaning of his apprenticeship, nor did he resist Yin Qingfeng, his brother-in-law, who was only nine years older than him, as a teacher for him.

After Li Chengqian became an apprentice, Changsun gave Yin Qingfeng another surprise. She wanted Li Chengqian's eldest sister, Yin Qingfeng's future wife, Li Yueli, to go to Wutong Villa together.

The reason is that the eldest grandson of the emperor was young after all, and Wutong Villa was far away from Chang'an. As his parents, it was inconvenient to take care of him, so his elder sister had to take over his mother's position.

I have to say that Yin Qingfeng likes this reason very much.

Although Li Chengqian was young, his future wife was only ten years old. When they arrived at the villa, it can be said that what kind of person Yin Qingfeng wanted them to become depends on his ability. Moreover, it is better to live under the same roof than to get familiar with each other after getting married.

I came to the East Palace to send three sets of aerobics, and when I left, I had an extra wife and an apprentice. It would be strange if Yin Qingfeng was in a bad mood.

Yuemei followed Changsun to be a coach. Yin Qingfeng, who was in a happy mood, returned to the Duke of Yun's mansion by himself.

After returning to the mansion, the first thing was to ask the uncle butler to go to the samurai mansion to deliver a post. He wanted to visit the mansion after dinner the next day. The second thing was to call Du Fuwei and his wife to have dinner together, and then discuss future plans.

Although Yin Qingfeng had already adapted to life in the Tang Dynasty, he never felt much close to Yin Yuan and Pei. Wen was this body and her biological mother, and perhaps because of natural bloodlines, Yin Qingfeng still respected her.

Since he had taught Li Shimin the health care exercises summarized by his grandfather, he would teach Yin Yuan and others the health care exercises together when Yuemei came back today. It would not be spread outside, but his family members would not know how to do it, and then it would be embarrassing at that time.

After getting off a nap, Yin Qingfeng took people to inspect the progress of the Ziwei Building.

It was also much easier to build a house in the Tang Dynasty than to build a modern one. After the foundation and drainage system were dug, the only difficulty was the laying of heating pipes.

Whether in the West or China, the habit of using firewood to cook has continued to be changed to coal and natural gas in modern times. The fundamental reason for the abnormal modern climate is still in the vegetation coverage rate.

Using coal instead of firewood not only reduces the damage to vegetation, but also allows the Tang Dynasty to create new economic growth points. The pilot project starts with the Qiweilou.

With so many stoves in the back kitchen of Ziweilou, a lot of heat energy is wasted every day. Now adding a simple heating system will not only not require an additional boiler room, but also increase the selling point of Ziweilou.

To use water circulation to keep warm, metal pipes and metal heat sinks must be used. With the strength of the two Dukes, these things cannot be done by themselves, but if you can take this opportunity to get closer to the warrior, why not do it?

Before the warrior became rich, he was a businessman. In terms of the amount of wealth, he had no chance to be on the list of ancient merchants. But who told him that he had a good daughter who had been famous for all eternity? For his daughter, Yin Qingfeng had to take the initiative to come.

If Yin Qingfeng only valued his daughter, the Duke Ying Mansion was really not worth his trip, and the identity of a warrior and merchant is the key.

People in the Tang Dynasty did not despise merchants, but not many people were recorded in history as merchants. Warriors may be the earliest one. Yin Qingfeng had to work hard on business, so how could he let the already successful warriors go without using it?

Wu Shiyu was born into a family of merchants in Bingzhou. He was originally a traveler, but later he took advantage of Yang Guangda's construction to start a timber business. It was because he made money on timber that he had the capital to fund Li Yuan's rebellion, thus obtaining unimaginable returns.

Judging from the news that Ren Liu found out, Samurai Teng's old business is still in the process, and his current business tentacles involve the textile industry.

Most people who did business in ancient times had a context: after buying land, they either planted grain and sold grain, or planted mulberry and weaving cloth. The latter was the latter.

According to Ren Liu, the land of Wu Shiyan is about twice that of Yin Qingfeng, which is more than two million mu of mulberry trees, most of which are used to plant mulberry trees. Based on the 4,000 plants per mu, there are 5 billion mulberry trees on his land. This data shocked Yin Qingfeng.

The leaves of mulberry trees are feed for mulberry silkworms, wood can be made into utensils, branches can be woven into baskets, mulberry skin can be used as raw materials for papermaking, mulberry can be used for edible wine, leaves, fruits and root skin can be used as medicine.

If these 5 billion mulberry trees belong to Yin Qingfeng, even if he has 100 sons, 1,000 grandsons, and 10,000 grandsons, his Yin family will eat and drink. But can the warriors do it?

But even if the samurai did not fully develop the value of mulberry trees, the business of raising silkworms and textiles was enough for the Wu family to spend money. Perhaps there were reasons for this in the past, the little loli and daughter of Wuzhao were kicked out of the house.

Yin Qingfeng's idea of ​​fighting the warrior is not a day or two, but his status was too low before and he didn't have enough weight to speak in front of the warrior, so he has been tolerant until today. Otherwise, no matter the wood needed by Xianjufang and the silk needed by the garment workshop, he could have cooperated with him.

But now it's different.

His current identity is destined to become the future son-in-law because of Li Shimin's successful rise.

Li Yuan now has four sons-in-law. The eldest son-in-law Feng Shaoshi is a confidant of Li Shimin's old Qin Wang Mansion. The second son-in-law Dou Dan is the nephew of Empress Dowager Dou's family, the third son-in-law is Chai Shao, and the fourth son-in-law was originally Changsun Xiaozheng, and now Duan Lun. These four people are all very glorious now.

Although the princess of Xiangcheng was born in a concubine, she was also the eldest daughter of the emperor. With this identity, Yin Qingfeng, coupled with Yin Qiao and the Warriors, was somewhat incense-provoking fate, and with the identity of the owner of the Qiweilou and Xianjufang, I believe that this sleek Yingguo Guild put down his value and dated him.

Before Yuemei came back, Du Fuwei and his wife had already driven to the Duke of Yun's Mansion with Duke Duke.

Du Fuwei was still full of tendons, and Shan Yunying was much richer in comparison. Du Fuwei sat next to Yin Qingfeng and heard Yin Qingfeng whisper about his trip to the East Palace yesterday. Shan Yunying over there played the talkative side of the woman and had a great time talking with Pei and Wen.
