"When I was a child, I once heard my alchemist master mention a papermaking method that seemed to be able to produce better paper at a low cost."

"Oh? How to do that?"

Cao Peng said: "I will tell you when I finish practicing boxing!"

"kindness!"

Huang Yueying will have great interest in all unknown matters.

Cao Peng taught Huang Yueying to practice boxing while trying to recall some past events. Although he was a criminal policeman in his previous life, he had been exposed to many aspects. Although many things were not that great in his previous life, in this era, they represent civilization and

progress.

For example, papermaking!

Although papermaking technology has been improved by Cai Lun, the cost of papermaking technology is still huge and cannot be used by ordinary people.

Also, printing...

Movable type printing is not too difficult in my impression, but if it really doesn't work, you can ask Yueying to study it together.

As soon as this thought came out, all kinds of strange and wonderful thoughts immediately came to mind.

Before, Cao Peng had no time, no experience, or even the ability to consider these things. Now, the Battle of Guandu has nothing to do with him, and he has been dismissed from his official position. That is to say, without an official, he is light and has a lot of time.

Let’s sort out these wonderful ideas.

As a time traveler, he may not be able to change history, but he can speed up the process of civilization.

Isn’t this also the kind of awareness that people traveling through time should have?

"Yueying, you practice boxing here first, I suddenly have some ideas, I will go back and record them.

After a while, I will discuss it with you..."

Cao Peng was impatient!

Huang Yueying agreed, and Cao Peng left in a hurry.

I had just passed through the arch and was about to walk to the study. I saw Hu Ban walking hurriedly towards Cao Peng along a path...

This time, Hu Ban returned to Xudu with Deng Ji. However, due to the many things at home at that time, Deng Ji did not take Hu Ban with him when he went to Meishan, but asked him to stay in Cao Mansion.

"Master!"

"Hu Ban, are you in such a hurry? Is there something wrong?"

"Young Master, someone from Dian Mansion has come and asked you to come over to the house immediately to talk."

Dianfu?

Cao Peng was stunned when he heard this.

Dianfu is Dianwei's residence.

However, Dian Wei is in Guandu now, and Dian Man is also in Guandu. Except for his father and son, the others in the Dian family are not familiar with Cao Peng.
