I pretend to be a fairy in ancient times

Yan Yunkai asked him to leave the capital tomorrow, Zhao Ji was very surprised, and asked with wide eyes, "I'm leaving tomorrow, are you in too much of a hurry?" Yan Yunkai asked him not to leave the capital a few days ago .

Yan Yunkai said calmly, "Everyone can't spare their hands now. These two days are the best time to leave Jian'an City. I will ask Lao Xing to prepare the luggage for you. I will also send someone to protect my grandma and aunt. , when you finish dealing with the matter in Sanjiang County and return to Jian'an City, you don't have to worry about any danger."

Zhao Ji felt that this so-called best time must have something to do with Yan Yunkai's hasty departure yesterday evening.

It's a pity that Zhao Ji couldn't ask directly before Yan Yunkai said it clearly, because it might involve state secrets.Since he regards Yan Yunkai as a friend, Zhao Ji feels that he should stick to his duty as a friend, and it is best not to ask about things that he should not know, so that this friendship can be maintained for a long time.

Zhao Ji immediately nodded in agreement with Yan Yunkai's proposal, and decided to leave Beijing tomorrow to go to Sanjiang County to reverse the case for Father Zhao, but he still has some ties in the capital, so he has to make reasonable arrangements.

The first is the safety of Mrs. Xia and Mrs. Xiao. Regarding this point, since Yan Yunkai has already planned, Zhao Ji doesn't have to worry too much.

In addition, Mrs. Jiang, who was still training at his home, had to ask Uncle Xia to take care of him.Mrs. Jiang had taught the two children of the Xia family. Uncle Xia was a well-informed and polite person, and he would definitely not refuse.

Uncle Xia also came to see last night, and gave Master Jiang an injection.Although Uncle Xia's position in the Tai Hospital is not high, but since he can enter the Tai Hospital, it means that his medical skills must be good.

Zhao Ji knew that acupuncture stimulation was very helpful for Master Jiang's recovery. Since the snake venom had been metabolized, it would not be a problem for Uncle Xia to take over the subsequent rehabilitation course.

And Chen Xing, Zhao Ji originally planned to wait for Chen Xing to pick up his mother to the capital, and then let Chen Xing drive him back to Sanjiang County, but he himself had to leave the capital first.

After a while, I have to explain to Mrs. Xiao and Liu Da separately, lest Chen Xing take his old lady to the capital and find no place to stay.

Finally, there is a question about Jiang Xu, who was just accepted as an apprentice this morning, but as a master, he will go out tomorrow.

Zhao Ji asked himself, a master like him is too unreliable.

Even if you want to be an unreliable master, you can't really ignore it. It seems that you can only advance the teaching of Jiang Xu's Arabic numerals to tonight, and then give her some homework.

This apprentice has just started teaching and is about to enter the stocking mode. Thinking about it, I feel a little guilty.

Once Zhao Ji accepted the decision to leave Beijing tomorrow, he quickly made preparations and arrangements in his mind before leaving Beijing.

It takes half an hour to travel from Zhao Ji's house to the National Teacher, but during the process of getting along with Yan Yunkai, just a few short words caused Zhao Ji to have violent psychological fluctuations.

Thinking about how long the next time will be, if he continues to stay in such a small space with Yan Yunkai, if there is nothing to do, he may not be able to help but think wildly again.

So, Zhao Ji took out a roll of paper from his bosom and handed it to Yan Yunkai, "These are the things I got from the immortals' words, if brother Jinghe can make real things, the benefits will definitely not be less than before alcohol."

"Oh~" Yan Yunkai was obviously very interested in this, and quickly took the blueprints handed over by Zhao Ji, and carefully looked at them one by one.

There are only five sheets of paper in total, and each sheet has graphics and detailed text descriptions. Zhao Ji's preparations are in place, and Yan Yunkai can naturally understand the content depicted on these five sheets without needing to waste words.

Although Yan Yunkai has the ability to see ten lines at a glance, he still read these five pieces of paper for 10 minutes repeatedly, because he felt that every word on these five pieces of paper was worth a thousand gold.

On the first piece of paper, there is a method of calculating accounts with tables. Yan Yunkai thinks this is a wonderful statistical method. Just list the tables, and the calculation of accounts will become very simple, and it can also eliminate most of the accounts in the books. Possibility of falsification.

On the second piece of paper, there was a strange figure drawn on it, which said flush toilet. Yan Yunkai took a closer look and found that it was similar in shape to a toilet.

The toilet is dirty to say the least, but it is an essential item in life.After Yan Yunkai read the written description, he felt that this kind of toilet was absolutely profitable.Because this kind of toilet that can be flushed at any time will definitely be sought after by the rich and powerful.

Zhao Ji may not know it, but Yan Yunkai knows very well that certain powerful families in Jian'an City, in order to eliminate the stench produced during the birth of Gong, spend as much money every year as enough to provide food and clothing for a hundred people without any problem.

As far as Yan Yunkai knew, for example, Empress Dowager Dong's mother's house, Cheng'en Gong Mansion, used several kinds of things just for Chu Gong, including incense ashes, burnt dates, goose feathers, and butterfly wings. One is more expensive than the other.

Although the cost of a flush toilet is not low, it is not worth mentioning compared with these expensive expenses accumulated over the years.In order to support their extravagant life, the Dong family did a lot of corruption and perversion of the law.

However, the Dong family still has a large number of loyal fans. The reason is that as long as they follow the Dong family and drink soup, they can make their brains full of fat.These people are blood-sucking insects attached to the court, Yan Yunkai must crush them to death.

Yan Yunkai thought that if someone could use the tabular statistics method Zhao Ji gave to secretly go to various places to check the accounts, he would definitely find out many moths, and even shake the foundation of the Dong family in the civil service system.

In this way, he can take a two-pronged approach, not only to regain the military power of the Gyeonggi Camp, but also to eradicate the scum in the civil servants.

On the next two sheets of paper, the method of making the pencil is recorded respectively.There is also a mineral called graphite that can replace the smoke ink used today to print books.

In the last years of the Chen Dynasty before the Jin Dynasty, the printing technique had been widely used, and the engraving printing technique could already make colorful New Year pictures, so there was no need for Zhao Ji to promote it.

Due to the development of printing technology, various novels and travel memories after the founding of the Jin Dynasty were published in large quantities, and the price is generally around one tael of silver, which is not cheap for Zhao Ji, but he has not found a more interesting way of entertainment than reading novels Yes, so recently I have been reading novels to pass the boring time.

Because the ink ingots used now are all made of artificially collected pine branches and smoke from grease, the cost is very expensive.Zhao Ji hopes to rely on the power of Yan Yunkai to mine graphite mines and replace the smoked ink that is commonly used today with graphite. The price of books will definitely drop in the future, but the business of graphite can make a lot of money.

Reading in this era is a very expensive thing, and the price of paper, pen, ink and inkstone is high.If you have a pencil, you can save a lot of money with just three things: pen, ink and inkstone.If the popularity of pencils gets its way, more people will surely read books.

Of course, Yan Yunkai can see the long-term benefits. Even if he doesn't consider the long-term, as a person from the army, Yan Yunkai will subconsciously think of the use of pencils in war.

Whether it is the rolling mountains in southern Xinjiang or the flat grasslands in northern Xinjiang, it is easy for people to get lost due to the terrain. This invisible obstacle has brought great obstacles to the military operations of Dajin.If he had this portable pen, he could send scouts to sneak into the mountains and grasslands and draw a detailed map. In the future, no matter whether it was the northern or southern borders, Yan Yunkai had the confidence to make them bow down.

The last one is something called a shower. Its principle and method are similar to those of a flush toilet, but Yan Yunkai is not very optimistic about its value.Because there are soup pools in the homes of the rich and powerful, and the rich are also accustomed to barrel baths, but Zhao Ji’s shower also needs to be installed with hot water on the roof in advance before it can be used, which is time-consuming and laborious, and has no high promotional value.

After Yan Yunkai told Zhao Ji his opinion, he gave Zhao Ji a new idea.Since the rich and powerful do not need to use showers, do the ordinary people at the bottom need them?

Bathing is a very troublesome thing for ordinary people. Although water does not cost money, firewood and carbon do.

Zhao Ji also saw that there is a bathhouse in Jian'an City, which is a pool of water, the kind where countless people wash.Huang Qi said that the business in the bathhouse is not good in summer, because you can take a cold bath. In winter, the business in the bathhouse is particularly good. The housekeeper of the Xia family, Lao Zheng, once took him to have a bath, and the price was very cheap. It's only a penny. If there are ten people going together, only three big pennies will be charged, that is, nine pennies.

But Huang Qi also said, "The water in the big bath, after washing too many people, will eventually become like mud." At that time, Zhao Ji didn't take it too seriously.

Now that I think about it, the hygienic situation in this era is really worrying. In this case, bacteria and viruses are very easy to breed. It is no wonder that most people in this era have a short life span. If they can live to 50 years old, they are already undisputed elderly people.

This is still the situation in Jian'an City. If it is a remote countryside, the situation is even more dire.

In this case, if he came to open a shower and bathhouse, he was making a contribution to public health.But according to his original idea, after boiling hot water, it is not cost-effective to lift it to a high container and then take a shower.

Now Zhao Ji thought of a better way to burn the boiler.

When he was young, his uncle often took him to wash in the public bathroom of the unit. The old bathroom used a boiler to heat hot water.

He knew that it was not difficult to build a boiler. There was a charcoal-burning stove on the lower floor, filled with water, and then a pool was built. The steam heated by the boiler was passed into the pool through iron pipes, and the temperature of the steam was used to heat hot water.

It is best to use coal to burn boilers. Since Yanyun has been allowed to mine graphite mines, and then open a coal mine by the way, there should be no major problems.

What's more, both graphite and coal are black stones, and the stock is not small. When Yanyun opens, let people go to find ore, maybe they can find both.

Yan Yunkai discovered that while talking to Zhao Ji, he suddenly fell into deep thought.

Yan Yunkai looked at the five thin sheets of paper in his hand, and thought that Zhao Ji's novel ideas might be born out of this kind of meditation.Thinking of this, he didn't speak again, for fear of accidentally interrupting Zhao Ji's train of thought.

Yan Yunkai originally thought that Zhao Ji was a rare treasure in the world, but now Yan Yunkai firmly believed that he must have been favored by the heavens.

The author has something to say:

Zhao Ji's crossing golden finger finally started to explode.
