Inside the thatched hut.

Zhou Yu calmed down the breath of his body and began to feel his body again.

He felt that his body had instantly become several times stronger, and his meridians, divine sense, soul, and so on had all improved significantly.

And the most noteworthy thing among them is naturally the changes in his dantian.

Because of the breakthrough, the planets in his dantian became larger than before, and the light emitted was also more brilliant.

You can feel a powerful force from above!

This planet can be said to be the source of Zhou Yu's current strength, which contains all the energy in his body.

And if you want to cultivate the planet, you also need a lot of life force.

These life forces are also mainly extracted from spiritual power.

This is a difficult process, and if he refines it slowly, I am afraid it will take a long time to reach the current point.

But with the addition of thirty years of systematic cultivation, he reached it in a moment, and the vitality of the planets in the dantian was full to the extreme!

Now, his strength has been raised to the peak of Xingzhou, which is equivalent to the peak of the Heavenly Immortals in this world.

He only needs to go one step further to impact the Xuan Immortal Realm!

Of course, although it seems like a millimeter of distance, it is still difficult to break through.

Now Zhou Yu is not the little monk he used to be, after becoming an immortal, the slightest gap in strength will take decades, or even thousands of years, to fill in before it is possible to advance.

He felt that it was faster to get the cultivation by lottery.

He checked the "Douzi Secret" and the "Dan Sutra" he had just obtained in his backpack again, and even though he put it aside for the time being, he was not in a hurry to cultivate.

These are all very profound things, and they can't be cultivated successfully overnight, so let's talk about it after dinner first.

The rice should be eaten one bite at a time, the road should be walked step by step, and it is easy to pull the egg when the step is big.

So he opened the wooden door and came to the farm in a happy mood.

But at this time, Ying Zheng and the monkey had already prepared a hot dinner, and sat on the side and waited.

Apparently waiting for himself to eat.

Zhou Yu walked over and found that Ying Zheng was holding a bamboo slip in his hand at this time, watching intently.

However, it seems that the bamboo slip on it is not good news, because Ying Zheng's brows are furrowed and his face is worried.

Obviously, there is something very important on this bamboo slip. Otherwise, he wouldn't have brought it to the farm.

In fact, Zhou Yu's guess was not bad.

This bamboo slip is indeed a very important policy of Great Qin, if Fusu is allowed to make mistakes, the consequences will be very troublesome. And Fusu's handling method made Yingzheng very dissatisfied.

But he couldn't think of a better way for a while, so he was worried.

Zhou Yu couldn't help but shake his head when he saw Ying Zheng holding a heavy bamboo slip in his hand, which looked very inconvenient.

It occurred to him that paper had not yet developed in this era.

Perhaps, this thing can be made in advance!

Zhou Yu felt that if he could teach Ying Zheng how to make paper and bring it back, he should also be able to promote the development of Daqin.

At that time, Ying Zheng's cultivation of the Son of Heaven Sealing Divine Technique can also be twice the result with half the effort!

After all, Ying Zheng has been on his farm for a few days, and although he hasn't done much work, he has triggered a lot of rewards for himself.

But he only taught him a copy of "Tunaju", and he couldn't teach him other magical powers in a short time.

It's a bit unreasonable.

Zhou Yu took all the benefits himself, and he should give back to others appropriately, this is his criterion for being a man.

This "papermaking technique" is a good way to compensate him.

Immediately, Zhou Yu took out a blank piece of white-green jade slip and entered some of the expositions of papermaking technology in his mind in later generations.

After checking it and making sure that Da Qin could make it, he handed it to Ying Zheng and said:

"Ying Zheng, this is for you, you can take it back to study."

Ying Zheng was still reviewing the bamboo slips, and when he heard Zhou Yu telling him to raise his head immediately, he took the jade slips handed over by Zhou Yu.

He found that this jade slip was a beautiful and clean white-green color, similar to some beautiful jade in the mortal world.

But there is a faint emerald green light looming on it, obviously an aura!

He probably guessed what it was.

Legend has it that the immortals did not use bamboo slips to record their exercises and supernatural powers, but instead used a magical instrument called jade slips.

A small jade slip can fit a long article, which is mostly used to record important things.

Now, the immortal chief has given himself a jade slip, and he must be teaching himself supernatural powers again!

Thinking of this, Ying Zheng suddenly became excited, and thanked Zhou Yu:

"Thank you Immortal for the Fa!"

After Zhou Yu saw Ying Zheng's excited appearance, he knew that Ying Zheng probably misunderstood.

But he didn't say anything, just nodded and let Yingzheng check.

Ying Zheng immediately probed his consciousness into the jade slip.

I saw a few big words appear in my consciousness: papermaking

Even if it is a text that deals in detail with how to make paper.

After seeing this, Ying Zheng was shocked and a little puzzled.

The appearance of the jade slip that the immortal chief gave himself didn't seem to be a magical power, but a technique for making things?

Looking at the meaning revealed between the lines, the immortal chief is teaching himself to make an item called 'paper'?

But what is this paper? And what can be done?

Ying Zheng was slightly disappointed in his heart, but he did not immediately lose interest, but chose to continue watching.

He knew that since the Immortal Chief had given him this thing, he must have some purpose.

It can't be groundless.

In this way, when he knew that the paper made by this papermaking technique could be used to record words, and it had the advantages of being lightweight, easy to write, smooth, tough, foldable, stiff, and easy to preserve, he was immediately shocked!

This is a fetish specially designed for writing words!

His original disappointed mood was suddenly extremely excited, if it weren't for the fact that his consciousness was in the jade slip at this time, he would have to jump up on the spot!

The immortal chief is really powerful, not only has all kinds of magical powers, but also has this advanced technology!

This is a great wealth for yourself!

Although it is not an exercise, it cannot be cultivated.

But once this 'paper' is made, it can completely replace this bulky bamboo slip!

If it can be popular in Daqin, the efficiency of the government, the learning efficiency of students, the efficiency of reading and folding, etc., will be significantly improved!

In the future, why bother to review the folds yourself?

For example, the reason why there are so few people reading today is because reading is too hard. The books recorded in bamboo slips are too precious for ordinary people to afford.

If you use this paper to make books, you can solve this problem!

It's countless times better than that bamboo slip!

In fact, long before this, Ying Zheng felt that this bamboo slip was very cumbersome, very troublesome to use, and could not write a few words, so it was easy to decay.

It's just that there's never been a solution.

Now the arrival of this papermaking technology is simply a charcoal in the snow, and the dark room is full of lights!

It's even worth more than a supernatural power!

Immediately, he transferred his consciousness back from the jade slip, held the jade slip tightly with both palms, as if he was afraid that the jade slip would fall, and thanked Zhou Yu again with tears in his eyes:

"Thank you Immortal for giving me paper-making skills!"

"With this papermaking technique, why don't I worry that Daqin will prosper?"

Immediately, he couldn't wait to ask Zhou Yu:

"Immortal Chief, please allow me to leave now!"

Zhou Yu asked in surprise:

"Let's go now, you don't have dinner?"

Ying Zheng said firmly:

"I don't want to eat it, I want to go back immediately and arrange for the paper to be made!"

Zhou Yu saw that Yingzheng couldn't wait, so he didn't leave him, nodded and said:

"Then you can go back."

Ying Zheng nodded, summoned the light gate, and immediately left the farm.

The farm calmed down.

He and the monkey began to eat.

The monkey asked Zhou Yu curiously:

"Immortal Chief, what good things did you give to the second junior brother? Why is he so excited? ”

Hearing this, Zhou Yu replied:

"It's a technology called paper."

"This paper is of no use to you, but it is of great use to the Terrans today."

Hearing this, the monkey nodded blankly, stopped asking, and continued to eat silently.

But at this moment, the monkey's eyes glimpsed the place where Ying Zheng had stayed before, and found that there was still a bamboo slip left, which was the pile that Ying Zheng had reviewed before.

Obviously, Ying Zheng was in such a hurry that he even forgot to take the bamboo slips with him, and he couldn't help complaining:

"The junior brother is too embarrassed. Leave this pile of bamboo here, what if my grandson accidentally burns it as firewood? ”

On the side, Zhou Yu also noticed the pile of bamboo slips, and couldn't help but be curious, so he picked up one and looked at it.

The text on the bamboo slip is Qin Seal, but Zhou Yu has also learned this kind of text before, so he can understand it.

Seeing this, he understood why Yingzheng was sad just now.

It turned out that there were people in Daqin who ate rock salt, that is, mineral salt.

The salt was not processed, resulting in mass poisoning in people who ate it.

However, Fusu's handling of this matter is to directly ban the consumption of mineral salt by the people throughout the country.

Obviously, Ying Zheng was not satisfied with this method of Fusu. I guess I thought of another level.

Although mineral salt is toxic, long-term consumption is not small to the human body.

But now that there is a lack of experiments in Daqin, if it is completely banned, how can it not cut off the people's way of life?

After reading this bamboo slip, Zhou Yu couldn't help but smile slightly.

Definitely, by the way, I also taught Yingzheng the method of refining refined salt.
