Those who are confused come and those who are confused go.

Regarding the purpose of calling him to ask for the medical book today, Li Yuanjia had the courage to ask the emperor, but Li Shimin did not answer at all, so he drove him away like a fly.

On the way back, Li Yuanjia sat in the carriage and thought of many possibilities.

Do you want to be a dead horse as a live horse doctor, and ask yourself if there is a way to treat your eldest grandson? Or do you want to beat yourself up and let yourself worry about the reputation of the royal family? Or ......

"Hehe, you can't want me to compile a medical book like Li Tai, right?"

Suddenly thinking of a possibility, Li Yuanjia immediately shook his head, and he was amused by his own thoughts.

How can it be?!

In China's thousands of years of history, there have been subsets of classics and histories compiled by official organizations, geography books, and even agricultural books, but are there medical books compiled by official organizations?

Maybe there really is, but at least in Li Yuanjia's own memory, those most famous medical books should be personal works, such as Wang Shuhe's "Pulse Meridian", or in the long history, some doctors have been accumulating and summarizing the works, such as "The Yellow Emperor's Neijing", but there seems to be no official organization to compile them.

Even if Wang Shuhe was the imperial physician at that time, writing a book was still his personal behavior.

The reason for this is actually very simple, after all, not to mention doctors these days, carpenters, blacksmiths, papermakers and inksmiths, etc., which one does not take care of his little ability as a treasure? What I am afraid of is that I have taught my apprentices and starved my master to death, even if I am old, I am afraid that my sons and grandchildren will starve!

Most of the doctors in the world have the same idea, counting on gathering them together to write a set of medical books to train doctors? Li Yuanjia felt that even Li Shimin didn't dare to think so......

"Huh? No way! ”

Thinking of the second brother of the emperor he had just met, Li Yuanjia suddenly remembered something, and immediately regretted patting his thigh on the carriage: "What a great opportunity just now, why don't you tell him about the last dynasty?" Ouch, I missed this time, and I don't know when I will have such a good opportunity next time! ”

Li Yuanjia, who was annoyed and regretful, couldn't have imagined what Li Shimin wanted to talk about when he came to him today, let alone that the next time the two talked about this matter, it would have to wait until ten years later......

……

A chance summons was soon forgotten by Li Yuanjia.

As the king of the Tang Dynasty, in addition to going to the Daxing Hall and the Liangyi Hall every day to go to the court, and resting for ten days, the previous Yongzhou pastor did not bring much change to Li Yuanjia's life.

I still live my own little life, I still concentrate on writing, I pay attention to the "research progress" of the craftsmen, and I still close my doors......

Of course, almost no one came to visit him.

Before leaving the cabinet, Li Yuanjia basically lived in the deep palace, and almost no outsiders were seen except for a few teachers; And immediately after leaving the cabinet, he went to Luzhou, and he didn't even look at the nobles in Chang'an, and basically didn't know anyone.

Moreover, Chang'an City is not Luzhou, and everyone's attitude towards him is completely different.

In Luzhou, Li Yuanjia is a thorn in history, the highest governor of a state, and he is also the prince of the Tang Dynasty who needs others to look up to, even if he knows that he doesn't care, the officials desperately want to play with him or something. But in Chang'an City, although the title of prince is equally dazzling, the nobles don't take him very seriously.

A prince who has no real power, has a hairy use?

In these years, even Li Shimin has to make a special decree to let the ministers respect his own son, not to mention that he is a king of Han who is not loved by his grandmother and uncle?

If you have to say that there are still people who have dealings with each other, it is also Uncle Yu Wenshi and the future father-in-law Fang Xuanling's family, as well as a few people such as Yongzhou Governor Shi Yangsu.

So except for the fact that every morning was quite painful, forcing Li Yuanjia to change his work and rest habits and go to bed when it was dark, in fact, there is no essential difference between life in Chang'an and Luzhou. Even the papermaking workshop and blacksmith workshop were built outside Chang'an City, and Li Yuanjia had to wait until the next day to find out about the situation, which made him extremely unhappy, and even began to miss the Luzhou Government Office thousands of miles away......

Sometimes, Li Yuanjia also feels that his life is really boring.

Especially in my last life, I read so many time-traveling novels, and almost all the protagonists' lives are much more exciting than TV dramas and movies, but I have been traveling for six or seven years, and I still live as an otaku every day, and I don't even have a woman every day!

Fortunately, it was quite interesting to come here and do inventions.

Although Li Yuanjia can't always go to the paper workshop or blacksmith workshop in person because of his identity, it is really good to organize a "scientific research team" by himself, and then watch them make things that do not belong to this era little by little!

What's more, Li Yuanjia was not idle in his own palace.

After Huang Licheng arrived in Chang'an with Han Shan, the Han Mansion in Shengyefang finally began a complete renovation in mid-May – the sewer system was only one part of it.

Like Luzhou, Li Yuanjia didn't use anyone else this time.

All of them used the palace's own manpower, and he also asked Li Zhong and other five little guys to be responsible for "supervising the work" this time, and then submit a project plan for the next stage and a summary of the project for the previous stage every ten days. No matter how disgusting the things these guys write, Li Yuanjia will insist on scoring them, and occasionally when he sees a reliable one, he will reward one hundred or two hundred articles, which can be regarded as a small encouragement......

Just like this, day by day, Chang'an City finally entered the summer of Zhenguan ten years.

In mid-June, Wang Pu and Niu Da Niu Er brought Li Yuanjia a whole box of white paper again - although the papermaking workshop has not been completely completed, it does not prevent Han Lucheng from buying the raw materials they want in the spring of this year, and first built simple papermaking tools, which also does not prevent Wang Pu from starting work as soon as they arrive in Chang'an, and the first batch of white paper was produced in early June.

The quality of this batch of white paper surprised Li Yuanjia very much!

If the quality of last year's batch of white paper reached the level of tribute from the Li Family Paper Mill, then what Wang Pu made this time can be said to have completely surpassed their opponents!

It's a lot whiter, and it's a lot tougher.

But for Li Yuanjia, the more important point is that the water absorption of white paper has been greatly improved. After asking Wang Pu, I learned that they used a new plant extract at the end - to put it bluntly, it was added to the pulp with the juice of some kind of vine!

And just for this box of paper, Li Yuanjia excitedly rewarded each person with fifty pieces!

But this time, before Li Yuanjia sent the newly made white paper to His Majesty the Emperor, a bad news came out of the palace: it turned out that there was no use in overhauling the world's Buddhist temples, and after a few months of hard work, the eldest grandson of the queen of the Tang Dynasty finally failed to survive this summer and collapsed in the Lizheng Palace......
