When Zhao Dan heard the news of Xun's arrival, the monarch of Zhao was struggling to review the folds.

After knowing that Mi Xian had come to report the news that Xun had entered the palace, Zhao Dan raised his head from the mountain of folds in front of him, and said to Miao Xian in front of him: "Quickly invite Xunzi into the palace!" ”

After saying this, Zhao Dan straightened his body, rubbed his somewhat sore wrist, and then stretched his waist hard.

To be honest, in this era, due to the existence of bamboo slips, it is really a physical task to review the folds, and Zhao Dan, who has been reviewing the folds all morning, feels quite tired as soon as he relaxes

Just when Zhao Dan moved his wrist, he suddenly thought of a legend in history.

It is said that Qin Shi Huang was extremely diligent in his administration, and would review hundreds of catties of folds every day, even when he was out on patrol.

So the reason why Qin Shi Huang did not become a long-lived emperor may also be because it is related to the high-intensity manual labor carried out in adulthood...

Although this is just a cranky thought, it reminds Zhao Dan of one thing, that is, the improvement of papermaking is imperative.

As we all know, Cai Lun in the Eastern Han Dynasty was usually associated with papermaking, but strictly speaking, Cai Lun was not the inventor of paper.

In fact, in the Spring and Autumn Period and the Warring States Period, there was already the appearance of paper.

China is the first country in the world to raise silkworms and weave silk. In ancient China, the working people of the superior silkworm cocoons drew silk and weaved silk, and the remaining evil cocoons and disease cocoons were made of silk cotton by bleaching method.

When the bleaching is completed, there will be some residues left on the mat, and the waddles on the mat will accumulate into a layer of fiber flakes after the bleaching, which can be used for writing.

The number of by-products of this drifting is not much, and it is called Heyi or Fang Fu in ancient books, which is the silk silk that Zhao Dan often used to write secret letters.

But the problem is that the output of this kind of silk is so scarce that even Zhao Dan's paper needs cannot be met, let alone anything to replace this bulky bamboo slip.

The so-called papermaking in history usually refers to Cai Lun's improvement of papermaking in the Eastern Han Dynasty.

After Cai Lun's improvement, paper finally began to become popular on a large scale because of its cheap and easily available raw materials, and finally completely replaced bamboo slips.

Even in order to prevent himself from being exhausted at a young age because he carried hundreds of catties of bamboo slips on the table every day, Zhao Dan felt that he would be able to drum up this papermaking technique as soon as possible.

But what made Zhao Dan feel a little painful was that Zhao Dan didn't know what Cai Lun's improved papermaking technology was all about, and what the specific process was.

But fortunately, Zhao Dan is not completely ignorant, after racking his brains for memories, Zhao Dan finally remembered that the raw materials of Cai Lun's papermaking should be made of bark and rags, and then there should be a step called pulping in the process of papermaking.

Then Zhao Dan couldn't remember.

This made Zhao Dan also feel a little emotional, other traversers can know everything well after the crossing, as long as the things they have seen in Baidu can be easily recalled, why don't they have such a strong ability?

So Zhao Dan simply left this task to the craftsmen of Zhao State to slowly study and explore.

Judging from the current situation, it is obvious that the craftsmen of Zhao State have not yet found anything decent.

This reminded Zhao Dan of a famous school in the Spring and Autumn Period and the Warring States Period, and Confucianism was called "Xianxue" Mohist.

You must know that the Mo family still has a lot of experience in this kind of manufacturing things, and there have been top masters like Lu Ban, if there is help from the Mo family, then I think it should be possible to make the improvement of papermaking more smooth.

For this reason, Zhao Dan also quietly sent Hu Yiwei to search for the traces of the disciples of the Mo family.

However, since the Warring States period, the Mo family has gradually declined, and now it has almost completely disappeared at the end of the Warring States period, and its members are no longer as openly active among the countries as before, so they have not been discovered by Hu Yiwei until now.

Of course, given that Zhao Dan had only just crossed over a few months, and Hu Yiwei's infiltration of the other six countries had just begun, Zhao Dan was not in a hurry.

Things like papermaking and finding the Mohist aren't too important.

In Zhao Dan's view, what Zhao desperately needs now is a reform that can make Zhao more powerful.

As we all know, during the reign of Zhao Dan's grandfather, King Zhao Wuling, Zhao Guo once carried out an extremely famous reform called "Hufu Cavalry Shooting".

It was precisely because of that reform that Zhao's border cavalry regiment rose rapidly to dominate the countries, and Zhao's overall combat effectiveness also increased greatly, thus opening the prelude to Zhao's step-by-step strengthening in the middle and late Warring States period.

However, the reform of King Wuling of Zhao was not thorough, because this reform was mainly focused on the military aspect, and there was little involvement in the institutional aspects of the Zhao State.

As a traverser, Zhao Dan knew very well that the reason why the Qin State was able to finally dominate the world was because of the whole system established since the Shang Dynasty changed the law.

In the whole set of systems established by Shang Ying, although the military merit system is a relatively important part of it, it is not the whole system.

At the time of the reform of Zhao Wuling's Hufu cavalry and archery, although Zhao also borrowed and basically copied the military merit system of Shang and Qin, it was nothing more.

In fact, even the implementation of this copied military merit system in Zhao was far less thorough than that of Qin.

Ever since the crossing, Zhao Dan has been trying to find a way to solve this problem.

Obviously, Zhao's system was more backward than that of Qin.

To paraphrase the words of the high school political textbook in the so-called "Three Divine Books of the Traveler", that is, "the superstructure and the relationship between the productive forces of the Zhao State today can no longer meet the growing demand for productive forces." ”

Today, the six states of Shandong, including Zhao, are still in the social structure of the slave system, while the Qin state, which has completed the Shang Dynasty reform, has taken the lead in entering the feudal landlord system.

In the current era, the system of the Qin State is undoubtedly extremely advanced and leading.

If you fall behind, you will be beaten, Zhao Dan remembers this sentence very clearly.

Don't look at Zhao Guo now that he has won Changping and is already the hegemon with Qin, but as long as the disadvantage of the system is here, then Zhao will naturally have some disadvantage in wrestling with Qin, which is undoubtedly unbearable for Zhao Dan.

Therefore, after solving the crisis of the Battle of Changping, which he faced after the crossing, Zhao Dan's eyes were finally on reforming the system and changing the law to become stronger.

And Zhao Guo's hope for changing the law to become strong, Zhao Dan felt that it should be placed on the body of Xunzi Xun, one of the hundred great powers of the sons who was about to meet him.
