After the matter on the bandits' side was dealt with, Li Hao came to arrange for the departure back to the camp in Tanxian County.

The transportation of money and property in the spoils of war is quite convenient, just find some carriages to load things, and it doesn't cost much.

However, it takes some effort to escort a group of captives, and these Li Hao plan to escort them back to Jiaodong, so that they can directly act as workers in the paper workshop.

This not only reduces expenses, but more importantly, confidentiality is more guaranteed.

After all, after these captives go back, the right of life and death is on their own, and there is no interpersonal network in Jiaodong, as long as they are supervised, there is no need to worry about leaking secrets.

However, because Li Hao still planned to spend time in Xuzhou to see if there was still a chance to fight again, he couldn't let his subordinates go back directly with the captives.

So Li Hao hurried back to Jiaodong to find the Liang family, and asked her to send someone to Tanxian to meet and bring back a group of prisoners.

Because of the drag of the captives, the process of returning to Tan County this time was not so fast, and it took seven days to return smoothly.

Borrowing this time, it made Li Hao, Wan Songbai, and Cheng Shi more and more familiar, if it weren't for the fact that this age was really a little worse, Wan Songbai would almost have to bow to Li Hao.

It was this familiarity that made Wan Songbai remind on the road: "That day to attack the bandit camp, I see that the siege equipment you used is quite novel, we have not seen the state pastor in the past, but the Yuan family has recently made it?" ”

Li Hao had already expected Wan Songbai to ask about this, after all, as veterans of the battlefield, it was impossible for Wan Songbai and Cheng Shi not to see the role of these two things.

And Li Hao is also ready to hand over this thing, after all, the world is in chaos, this weapon for attacking the city must be given to Emperor Wen, otherwise if it is unfavorable to fight any city in the future, the army will be lost.

I'm afraid that whether it is because of the siege equipment or not, it will remind Emperor Wen of the fact that the Yuan family does not offer treasures, so he will be angry with the Yuan family.

Since they all have to be paid, it is also good to give full play to the surplus value, teach Wan Songbai and Cheng Shi together, and bring the relationship closer.

Of course, Li Hao will not send it directly by himself, that is really a bit of a price drop, so he has to let Wan Songbai speak first.

He replied: "That's true, this is after my father served in Xuzhou, I asked the craftsmen in the family to improve it, but it has not been practiced, and I don't know how effective it is, so I didn't give it to my father."

However, this time, it seems that these two things are indeed beneficial for the siege of the city, and when I return to Tancheng, I will tell my father about these things, and leave the corresponding craftsmen behind. ”

Who knew that Wan Songbai heard this, but he didn't answer again, but chatted with Li Hao about the gains and losses before and after the battle, which confused Li Hao.

It wasn't until Li Hao and Yuan Pei talked about this matter later that they understood how shrewd Wan Songbai was.

After returning to Tan County, because the people from Jiaodong had not yet arrived, Li Hao ordered people to set up a camp outside alone to guard the prisoners.

He went to Yuan Pei's side with Wan Songbai and Cheng Shi to restore his life, and after Yuan Pei roughly understood the situation, he condoled Wan Songbai and Cheng Shi, and let them go down to rest first.

Then he said to Li Hao: "The rushing car and wooden curtain you just mentioned are really so easy to use?" ”

Li Hao replied: "That's nature, how can the things I get out be bad, of course, there must be defects, in order to strengthen the protection and power, their weight is not light, so there are requirements for the terrain."

In addition, they are made of wood after all, and although I have set up fire prevention measures, I can't bear them if I burn them with oil.

And the most important point is that the slightly larger cities have moats, and how to transport these things under the city is a problem. ”

Hearing what Li Hao said about all kinds of difficulties, Yuan Pei nodded, the first two questions are easy to say, because as long as it is a big city, the location chosen must be a convenient place for transportation, and the terrain is not much worse.

And fire prevention is not a problem, that is, without these siege equipment, the enemy will still use fire oil when it should be used, and if it is really burned, it will be done again, after all, wood is better than fire oil.

However, if it can't go beyond the moat, it can only be used to attack some small cities, and the effect of this thing will be greatly reduced.

Just when Yuan Pei was distressed about this, he suddenly saw Li Hao's calm appearance, and then thought of his son's thoughtful temperament, and his heart moved.

said: "This thing that passed through the moat, I'm afraid you're also ready, take it out and show it to me." ”

Li Hao smiled when he heard this, and replied: "My father still understands me, and he has been ready for a long time, but he didn't use it this time." ”

As he spoke, he took out a book made of paper from his arms and handed it to Yuan Pei, and said: "This book records several siege equipment developed by the craftsmen in Jiaodong, in addition to rushing cars and wooden curtains, there are also moat bridges and ladders, among which the moat bridge is used to cross the moat. ”

But when Yuan Pei took the book, he didn't look at the specific content, but studied the book itself.

He asked, "This is your new paper, which is indeed much stronger than the previous one, and its smoothness is not inferior to that of cloth."

Look at your mother's letter, saying that you think this paper-making technique is related to the future of my Yuan family, why is this? ”

Li Hao replied: "I should have discussed this matter with my father a long time ago, but I thought it was still early, so I was busy with the training of the trophies and delayed."

Since my father is asking now, then I will talk to my father about this matter, and ask my father what he thinks my Yuan family can stand on for a hundred years. ”

After hearing this, Yuan Pei didn't quite understand why Li Hao asked this question, but he still asked: "That is naturally my Yuan family's noble style, and I have always attached importance to the education of my children for a hundred years. ”

"My father is right, but I think the key to this is the word education, so what is used to educate people's hearts." Without waiting for Yuan Pei to answer, Li Hao said to himself: "That's the sage classics that I relied on, and the books that relied on the mountains and seas in the clan. ”

Yuan Pei still didn't quite understand what Li Hao meant, and asked, "So what does this have to do with paper?" ”

Li Hao didn't answer, but said, "Father, I'll show you something later, and you'll know what I'm going to say?" ”

Then he turned around and walked to the door of the tent, and called his guards to go and get a burden in his tent.

Yuan Pei was quite determined at this time, and no matter what Li Hao was tossing, he looked at the book by himself, and he was fascinated when he looked at it.

After all, Li Hao spent a lot of effort when compiling this book, and the basic template was to apply the "General Essentials of the Martial Arts" edited by Zeng Gongliang.

But on top of this, Li Hao has made great improvements, which not only have the general introduction and drawing of each siege equipment, including the size, materials, and even how to make all the details, Li Hao has explained them one by one.

In addition, there is a record of the process and effect of each of Li Hao's drills, it can be said that as long as you get this book, it will be clear how to do these siege equipment and how to use it.

Of course, whether it can really be made depends on the specific ability, after all, the production process of some high-end materials, Li Hao will not write it in the book, let others learn it.

Just when Yuan Pei was looking at it, Li Hao had already taken back the things he wanted, so Li Hao interrupted Yuan Pei.

When he came back to his senses, Yuan Pei watched Li Hao open the baggage, and took out a few pieces of white paper, a large seal, and a slightly different looking ink.

Then Li Hao spread the white paper on the table, and then dipped the seal in the mud, and covered it on the paper, and after the seal was taken away, he saw that more than a dozen words were left on the paper, and it was: In the past, Di Yao's smart Wen Siguang house will be inferior to the throne, these few big characters.

After Yuan Pei saw it, he said: "Isn't this the beginning of Yu Shu Yaodian in Shangshu, what is the ......?" ”

As he was talking, Yuan Pei stopped, obviously understanding why Li Hao said this.

Originally, the things used for writing were generally bamboo slips and cloth, of which the cloth was lightweight, and the writing was clear and could also be stamped, which was more convenient and comfortable to use than this paper.

However, cloth is now equivalent to money, and its use cost is too high, even if it is a prince and noble, it is impossible to use it from time to time.

And the bamboo slips, relative to the cloth, its cost is much smaller, but its shortcomings are also obvious, one is cumbersome, a volume of Shangshu a total of 25,000 words, the full text is written in bamboo slips, put up can be piled up in a small half of the room.

Moreover, the bamboo slips themselves are rough, which is not suitable for rubbing, and in the past, the seals were covered in the form of sealing mud, so the writing must be written manually, which limits the number of books.

In addition, bamboo slips are cheap, but after the amount is large, it is not something that small households can afford.

It is precisely for these reasons that most of the books in the world are hidden in the hands of the wealthy, princes and nobles, and the common people have no access to knowledge.

This also ensures that most of the people who can become officials today are from wealthy families, even if Emperor Wen has the intention to promote the children of the poor family, he can't find a few useful people.

But the action that Li Hao just demonstrated undoubtedly means that as long as paper is used, a large number of books can be rubbed, and the price of paper is not high.

Does that mean that the cost of learning knowledge is reduced, so that many poor people can also be exposed to layers that they have never been exposed to before?

You must know that the number of Hanmen is much more than that of the Yuan family, even if the probability of becoming a talent is low, the number of people who can become a talent will not be small, and then maybe in a few years they will be able to compete with the family family.

So after thinking about this, Yuan Pei asked solemnly: "The cost of this paper is geometric, and its production process can be limited." ”

Li Hao saw that Yuan Pei already understood, and replied: "This paper is made of bark, hemp, rattan, wheat straw, straw and other things, and the cost of every ten pieces of paper is about a penny.

As far as the process is concerned, there are not many difficulties, and the follow-up production needs to be increased as long as more manpower is added. ”

Hearing this, Yuan Pei became even more dignified, as the head of the Yuan family, the first thing he had to consider was the interests of the Yuan family.

The good thing now is that the paper is home-made, so the initiative is still in his own hands, and he can calmly think about how to use this matter to make profits for the Yuan family.

Of course, the basis of all this is that the white paper has not been leaked, so Yuan Pei asked: "How many people know the production method and finished product of this white paper, and whether it will be leaked." ”

Li Hao replied: "The people who participated in the development of the white paper are all old slaves of the Yuan family, and they have always been loyal.

After that, even the seal of this book was engraved by my own hands, and I never faked my hands to others, so I think that the group of craftsmen should not have noticed this.

Moreover, when I left, I explained that my mother was in charge of this matter, and it was naturally safe to use my mother's ability. ”

Yuan Pei's heart settled down at this point, and said to Li Hao: "You have given me a problem, but I want to ask you, what do you think?" ”

What can Li Hao think, as the son-in-law of the Yuan family, Li Hao is the beneficiary of today's scholar politics, and his ass is naturally sitting on the side of the scholar clan.

At first, Li Hao thought about making paper, mainly for his own convenience, after all, it was really too troublesome to write with bamboo slips.

After it was really made, Li Hao consciously felt that such a thing would change the status quo somewhat, so he stopped halfway.

But if you think about it carefully, even if Li Hao doesn't do this, someone else will do it in the future, just like Cai Lun didn't make paper more than sixty years later!

Anyway, since the Han Dynasty, many subsequent dynasties have been consciously promoting the children of the poor, and no one can stop this trend.

So it doesn't matter if it's a little earlier, anyway, in Li Hao's lifetime, the poor still can't challenge his status, that's enough.

Of course, this is not suitable to say in front of Yuan Pei, but he just said: "This matter should be decided by my father, where do I have any ideas."

It's just that I think everything should go with nature, after all, the art of papermaking has long existed, even if our family doesn't do it, won't others make it! ”

After hearing this, Yuan Pei lightly tapped the desktop with his fingers, thinking about Li Hao's words, and felt that it seemed to be the same.

After pondering for a while, he said, "Okay, stop the paper mill beforehand, and when I think about it again, you can go down first." ”

After Li Hao heard this, he was about to say goodbye and leave, but before he could reach the tent door, he was called back by Yuan Pei.

"I was also painted by you just now, is everything you wrote in the booklet you give me accurate?"

"Naturally, they are all accurate, I have tested these things in Jiaodong, and the content and pictures written in it are all described by me according to the real objects I made.

I guess this thing has to be reported to His Majesty, but the physical object is too cumbersome to transport, so I made this booklet. Li Hao replied.

After Li Hao said this, there was a flash of inspiration in his mind, and he figured out why Wan Songbai and Cheng Shi didn't mention the wooden curtain of the car.

Because they knew that as long as they told Yuan Pei about this, they would definitely hand over the things to Emperor Wen, and then they would naturally be able to learn from Emperor Wen, and there was no need to speak by themselves.

Come to think of it, Wan Songbai should have looked for himself for this at the beginning, but later he heard that he would hand over things to Yuan Pei, so he didn't answer.

Yuan Pei smiled when he heard Li Hao's words prepared in advance: "It's good that you can think of this, it is true that such a military weapon naturally has to be reported to Your Majesty."

Okay, you go down and rest first, and you can wait for my news about the rest of the matter. ”

This time, Li Hao left and was not called back, and he was finally able to rest in peace for two days.
