When Zhao Dan heard the news of Xunzi's arrival, the monarch of Zhao State was reviewing the memorial in a bitter way.

After knowing that Miao Xian came to report that Xunzi had entered the palace, Zhao Dan raised his head from the mountain memorials in front of him and said to Miao Xian in front of him: "Come to Xunzi into the palace!"

After saying this, Zhao Dan stretched out his body, rubbed his slightly sore wrists, and then stretched his waist vigorously.

To be honest, in this era, reviewing memorials was really a physical job. Zhao Dan, who had reviewed memorials for a whole morning, felt quite tired as soon as he relaxed.

Just as Zhao Dan was moving his skills, he suddenly thought of a legend in history.

It is said that Qin Shihuang was extremely diligent and reviewed hundreds of kilograms of memorials every day, even when he was out for inspection.

So the reason why that Qin Shihuang did not become a long-lived emperor may be related to the high-intensity physical labor he had been doing for many years...

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

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

In fact, paper appeared in the Spring and Autumn Period and the Warring States Period.

China is the earliest country in the world to raise silkworms and weave silk. In ancient China, the working people above the silkworm cocoons were drawn and weaved silk, while the remaining evil cocoons and sick cocoons were made by the floating floe method.

After the float is finished, some residual floe will be left on the bamboo mat. If the float is too many times, the residual floe on the bamboo mat will accumulate into a layer of fiber sheets. After drying, it will be peeled off and can be used for writing.

The by-products of this kind of floating floe are not large, and in ancient books it is called Heshou or Fang floe, which is the silk that Zhao Dan often uses to write secret letters.

But the problem is that the output of this kind of silk is too scarce, and even Zhao Dan's need for paper alone cannot meet, let alone replace the bulky bamboo slips.

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 low-priced and easy-to-get raw materials, and eventually completely replaced the bamboo slips.

Even if he was young, he was exhausted by carrying hundreds of kilograms of bamboo slips on the table every day, Zhao Dan felt that he would tinker with this papermaking technique as soon as possible.

But what made Zhao Dan feel a little painful was that Zhao Dan was not sure what the papermaking technology that Cai Lun improved was and what were the specific process flows.

Fortunately, Zhao Dan was not completely ignorant. After racking his brains to recall, Zhao Dan finally remembered that the raw materials for Cai Lun's papermaking should be made of bark and rags, and then there should be a step called beating during the papermaking process.

Then Zhao Dan couldn't remember it.

This made Zhao Dan feel a little emotional. Other time travelers can know everything well after traveling through time. As long as they have seen things from Baidu, they can easily recall them. Why don’t they have such powerful abilities?

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

From the current perspective, it is obvious that the craftsmen in Zhao have not yet figured out anything decent.

This reminded Zhao Dan of a famous school in the Spring and Autumn Period and the Warring States Period, and the Mohist school, who was known as the "explicit academic" together with Confucianism.

You should know that the Mohist school has a lot of experience in manufacturing, and has also produced top masters like Lu Ban. If you have the help of the Mohist school, then it should be able to improve papermaking more smoothly.

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

However, since the Warring States Period, the Mohist school has gradually declined, and in the late Warring States Period, it has almost disappeared completely. Its members no longer openly operated among the countries as before, so they have not been discovered by Hu Yiwei until now.

Of course, given that Zhao Dan had just traveled through time for only a few months and the infiltration of Hu Yiwei into the other six countries had just begun, Zhao Dan was not in a hurry either.

Things like papermaking and finding the Mohist school are actually not very important.

In Zhao Dan's view, what Zhao State urgently needs now is a reform that can make Zhao State stronger.

As we all know, when Zhao Dan’s grandfather, King Wuling, was reigned, the State of Zhao carried out an extremely famous reform called “Hu Clothing and Casting”.

It was precisely because of that reform that the border cavalry of Zhao State quickly rose and dominated the countries, and the overall combat effectiveness of Zhao State also increased greatly, thus opening the prelude to the progressive growth of Zhao State in the middle and late Warring States Period.

However, King Wuling of Zhao's reform of Hu clothing and cavalry was not thorough, because this reform was mainly focused on the military aspect, but rarely involved in the system of Zhao State.

As a time traveler, Zhao Dan knew very well that the reason why Qin State was able to ultimately unify the world was due to a complete set of systems established by Shang Yang since the reforms.

Among the entire system established by Shang Yang, although the military merit system is a relatively important part of it, it is not all.

When King Wuling of Zhao was reforming Hu clothing and cavalry, although Zhao State also learned from and basically copied Shang Yang's military merit system of Qin State, that's all.

In fact, even the system of military merits and titles copied was far less thorough than that of Qin.

Since traveling through time, Zhao Dan has been trying to solve this problem.

Obviously, Zhao's system is lagging behind compared to Qin.

To explain it in the words of the high school political textbook known as the "Three Great Books of Time Travelers", it is "The current superstructure and productivity relationship between Zhao State can no longer meet the growing demand for productivity."

Today, the six Shandong countries, including Zhao, are still in the social structure of slavery, while Qin State, after completing Shang Yang's reforms, has taken the lead in entering the feudal landlord system structure.

In this era, the Qin State's system is undoubtedly extremely advanced and leading.

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

Although Zhao has defeated Changping and become the hegemony of Qin, as long as the system is disadvantaged, Zhao will naturally have some disadvantages in the fight against Qin, which is undoubtedly something that Zhao Dan cannot bear.

So after solving the crisis of the Battle of Changping that we faced after traveling through time, Zhao Dan finally focused on reforming the system and strengthening the reform.
