Cao De returned to Hanzhong with 60,000 men. The www.biquge.info includes 10,000 Ruijin camps, 20,000 reserve camps, and 30,000 people who are about to enter labor camps.

The battle of Yizhou ended in just over two months.

It's the middle of June. And June is the time to dry the winter wheat that was planted last winter. On the way from Baishuiguan to Nanzhengcheng with a large army, Cao De could see people drying grain everywhere.

In order not to trample on the crystallization of the hard work of the peasant uncle, Cao De ordered the pace of the march to be slowed down, and anyone who dared to deliberately spoil the grain would be killed.

Due to Cao De's strict order, there was no accident on the way back, and of course there was no story of Cao Mengde's hair cutting and scapegoating in later generations.

After the army arrived in Hanzhong, the 60,000 returning soldiers should do what they should do, and Cao De also returned to the general's mansion after leaving for three months.

Before the Battle of Yizhou, Cao De's military rank was promoted from General Miscellaneous to General of Pingxi. Now the battle report of the Battle of Yizhou has also been reported to the imperial court with the return of Cao De. As for whether he can continue to serve as the general of Pingxi, Cao De has no idea in his heart. Of course, the battle report that Cao De sent to Liu Hong could not be the same as the one sent to Liu Yan.

The battle report that Cao De sent to Liu Yan was so lawless. If Cao De also sent Liu Hong such a battle report, the next thing would be that the Eighteenth Route Army would conquer Hanzhong.

Cao De is neither stupid nor stupid, so he will naturally write a battle report inviting merit. But Liu Yan will definitely tell the truth. Liu Yan couldn't wait to kill Cao De, and now that he has such a good opportunity, how can Liu Yan let it go.

As a result, Liu Yan described Cao De's lawlessness and rebellion in his war report, and almost half of the space on bullying the king.

However, this battle report did not reach the hands of Liu Hong in Luoyang. Even Hanzhong County did not go out.

Since Cao De did this, he must have no fear. In fact, Liu Yan's side has long been infiltrated by the black pearl. And the messenger sent by Liu Yan was stared at by more than a dozen eyes as soon as he received the battle report handed over by Liu Yan.

Soon, this war report was sent to Cao De's hands, and then Cao De sent someone to imitate the handwriting of this war report and forged one. Sent to Luoyang.

As for how Liu Hong will reward Cao De, he doesn't care. As long as you don't take away your official duties.

Cao De, who has nothing to do, has already begun to prepare a gift to seduce Cai Yong to run to Hanzhong.

Calculating the time, it is only three and a half months before the wedding day of Cao De and Cai Wenji. Cao De's position is not high or low, and he belongs to the mainstay of the Han Dynasty's official positions.

Therefore, there are many things that need to be prepared for Cao De's wedding. Cao De felt a headache after seeing the matters that needed to be prepared for the big wedding sent by the people below.

When Cao De married Ren Hongchang before, there was no one who participated in the wedding as a woman's delegation. Moreover, Cao De did not plan to make a big deal. So the wedding was very brief.

Now, behind Cai Wenji, who is about to become a bride, there is a huge family, and there is also a Cai scholar. This etiquette issue cannot be sloppy.

Cao De hated these tedious things the most. Therefore, Cao De threw everything to Xun Yu in one go, and then continued to prepare to seduce Cai Yong.

Who is Cai Yong, a bachelor in the dynasty! As the name suggests, Cai Yong is the most learned group of people in today's Han Dynasty. For them, the most important thing is knowledge. And where the knowledge comes from, of course, from books. However, the books that Cao De knows are not the same as the books that are circulating today.

You must know that a volume of "University" weighing three or four pounds in later generations now needs a carriage to pull it. In addition, the bamboo pieces on which the text is recorded can be easily damaged by moisture.

If Cao De put a staple-bound book of later generations in front of Cai Yong, how would Cai Yong react.

At this time, there was already paper, although that kind of paper was completely incomparable with the paper of later generations, and it was not something that ordinary people could use. But it didn't affect Cao De's idea of making a book at all.

And Cao De is now poor and has only soldiers, food and money. Just a book of paper really won't let Cao De take it seriously. And Cao De didn't plan to really rely on himself to accomplish this feat.

Cao De only needs to produce a few short articles to completely attract Cai Yong's mind.

After Cai Yong was successfully abducted to Hanzhong, the feat of creating books for later generations was Cai Yong's business.

The most important thing to make a book is paper, and although the quality of paper is not very good nowadays, it can still be used. Next up is printing. The simplest form of printing is movable type printing.

Movable type printing is not simple to say, but it is really difficult to say that it is difficult.

It is to engrave the words on a carrier of one square centimeter or even smaller, and then brush the ink and then print it on the paper. It is almost the same as the ink pad.

Cao De's biggest difficulty is the lettering. Fortunately, Cai Wenji is here now.

Cai Wenji is a talented woman who has obtained Cai Yong's true biography, and it is naturally easy to write a good hand.

At first, Cao De made a batch of small squares out of half-dried clay. So Cai Wenji made 100 experiments. Fortunately, Cao De did a small experiment in advance, if he really let Sister Wen Ji burn it together after writing it, it would be a real loss.

Because, after being baked at high temperatures, Wen Ji's sister's beautiful fonts have all become deformed!

In desperation, Cao De had no choice but to start looking for a replacement again! In this era, there is no plastic, which is sad for Cao De. In his previous life, Cao De used to take a private seal of radish for fun when he was young, so he couldn't use radish as a raw material. Although it is now popular to use stone and jade to carve seals, Cao De cannot afford to use jade, and it is too troublesome to use stone.

Just when Cao De was spinning around, Cao De suddenly thought of the most versatile thing in later generations. Wood!

So, one by one, the small wooden blocks that were made were sent to Cai Wenji. Then Cai Wenji wrote neat words on it. Then these written wooden blocks began to be carved according to Cai Wenji's handwriting.

When Cao De sent troops to Yizhou. This great project is in full swing. After Cao De returned with the army, a university that had been booked was delivered to Cao De's eyes.

When Cao De took the first book in this time and space, the excitement in Cao De's eyes was incomparable.

Immediately afterwards, the book was sent to Luoyang as quickly as possible.

At first, Cai Yong heard that his rogue son-in-law had given him a gift, Cai Yong pursed his lips, it was nothing more than some gold and silver treasures and the like.

At the beginning, Cai Yong also agreed to the marriage of Cao De and Cai Wenji in desperation. Cai Yong actually looked down on Cao De a little. I, Cai Yong, am a person who has read the books of sages and sages, and you Cao De are just a martial artist.

Now, Cao De sent someone to send gifts again. Cai Yong also went to the front hall with the idea of not wanting to be in vain, to see how much the gift from Cao De was worth.

After Cai Yong walked to the front hall, he saw only one person. There were neither extravagant processions to give gifts, nor elaborate boxes for gifts.

So, Cai Yong asked curiously: "What about the gift that your general gave to the old man?"

The trusted guard pulled out something wrapped in precious silk from his chest. Cai Yong took it curiously! What is this, it is still heavy to start.

Cai Yong slowly untied the silk, and the first thing that caught his eye were two words "University" that Cai Yong was very familiar with, and the handwriting that wrote these two words was also very familiar to Cai Yong. Can you not be familiar with it? This was written by your own daughter.

Cai Yong held back the shock in his heart and opened the first page. The dense small characters immediately caught Cai Yong's eyes.

"This ...... This is Cai Hou paper! …… Here's how to do it! Cai Yong said in shock!

The guard who delivered the book saluted and said, "The general asked me to bring a message to the scholars." The general said, 'This was created by my Cao Anbang. This thing is called a book by me! If your father-in-law wants a complete set of books, then come to Hanzhong County! My father-in-law was taken aback. ”

After hearing this, Cai Yong asked suspiciously: "Is this really made by your general?"

The guard replied respectfully, "The general still has a word, if my father-in-law has any doubts. Let my father-in-law bring all the bamboo slips he can bring. I Cao Anbang made it for him with his own hands! ”

Cai Yong was not calm after hearing this. The normal heart, which had gone through many winds and waves, also began to beat violently! (To be continued.) )
