Zhang Yu returned to Jiangdong, and this time he went out for two months.

In two months, Zhang Yu gained more than 300,000 points.

Zhang Yu dared to build roads, and this point is also an important reason.

Points can be exchanged for food directly, so Zhang Yu has this confidence.

"Lord, why are these people still cultivating the wasteland on a large scale, you must know that the agricultural time has passed at this time, and what is the significance of the reclamation at this time." Guo Jia asked.

When I first entered Huiji County, it was already more than five months, and the ordinary farming time had passed.

The rice has already been sown, and it is too late to plant it at this time.

"Lord, it's not easy to divert water on this mountainside, how can someone open up the wasteland?"

Guo Jia has more and more questions, along the way, Zhang Yu likes to investigate everywhere, and Guo Jia also follows.

Zhang Yu walked to some places and saw that after spring sowing, he began to reclaim a large amount of land.

Of course, Zhang Yu also had a plan, because the seeds were limited in the first year.

Zhang Yu exchanged one million points for sweet potato seeds, and the system will give 100,000 units of seeds, that is, rattans, and then want to have more points, one point and one rattan.

Therefore, the seeds are limited, mainly because Zhang Yu is reluctant to spend too many points, because there are still a lot of things to be exchanged.

"Part of this land is grown sweet potatoes and potatoes, and part of it is tea grown." Zhang Yu said.

"Sweet potato, potato?" Guo Jia asked.

"That's right, these are two edible plants that can be used as staple food, and the main thing is that the yield can be increased by more than twenty to thirty times." Zhang Yu said.

Guo Jia was stunned.

Yield increased dozens of times, what is the concept, that is, the same piece of land can feed dozens of times more people.

During the Ming and Qing dynasties, the population skyrocketed, and in the Qing Dynasty, it increased by hundreds of millions, and an important reason for this was the promotion of sweet potatoes.

"Lord, can you really increase grain production dozens of times?" Guo Jia asked in surprise.

Zhang Yu nodded, this sweet potato not only increases yield, but also manages well, and can be planted in many places, not as high as rice.

Guo Jia's heart surged, what kind of concept is this.

Huiji County can feed many people, and even don't have to worry about food in the future.

This will no longer be a remote place, but will soon prosper.

Guo Jia knew Zhang Yu's strategy, and constantly recruited displaced people in various places, plus there was enough food, and his strength soon became stronger.

Suddenly, Guo Jia felt that it was a very good choice to come to Huiji County.

Zhang Yu took Guo Jia and some guards to continue walking in the field, which would walk up a small hill.

On the mountain, there are patches of tea plantations that have been opened, and one of these tea gardens has been planted with tea trees and has grown tall.

"This year's autumn tea can be caught up." Zhang Yu looked at the mountain and said.

Guo Jia followed Zhang Yu around and found a lot of new things.

The quyuan plow in the field, as well as the waterwheel, all amazed Guo Jia, these are all great inventions, which can increase the existence of grain several times.

The reason is very simple, just say that the Quyuan plow, originally a person can be more than five acres, and the use of the Quyuan plough may be able to dozens of acres, which increases the planting area and increases the yield.

After walking around outside, Zhang Yu finally returned to the Taishou Mansion.

"Fengxiao, you are finally here, I have been happy for a few days to receive a letter from the lord." As soon as he entered the Taishou Mansion, Xi Zhicai happily greeted him.

"Zhicai really didn't deceive me, this will be really different from other places." Guo Jia said.

"Haha, okay, let's go in and talk, and call Zibu and them over." Zhang Yu said.

Xi Zhicai said to Zhang Yu: "Lord, as soon as I heard that you have returned, Zibu and they have already come." ”

In fact, Zhang Zhao and the others usually work in the Taishou Mansion, but there are too many things to manage, and they often go to the scene in person, so they are often not in the Taishou Mansion.

A few people went in, and Zhang Zhao and Xiang Heng were already waiting, but they were still busy with their hands now, and they didn't stop their work until Zhang Yu came in.

After Zhang Yu introduced several of them to each other, he got to the point.

"Zibu, you can tell me about the situation in Huiji County today." Zhang Yu said.

Zhang Zhao began to introduce that the population of Huiji County has not increased much, only tens of thousands.

However, there is a lot of land that has been reclaimed.

According to Zhang Zhao's statistics, Huiji County can feed at least several times the population.

"Look, my lord, what is this?" After the introduction, Zhang Zhao took out the paper on the table and said.

Zhang Yu had actually seen the paper, but he was not surprised at all.

"Lord, the paper is really done, and it can still be written normally, and we will no longer need bamboo slips in the future." Zhang Zhao said excitedly.

Zhang Yu calmed down a lot, but Guo Jia was not.

He had heard of paper, Cai Lun was from the Eastern Han Dynasty, he invented paper, but that paper could not be used at all.

But the paper that Xi Zhicai took out had words clearly written on it.

Guo Jia stood up, rushed over, and took the paper.

"It's paper, it's really paper, and the texture is so good." Guo Jia took the paper and stroked it, his face was excited.

Guo Jia was very excited, although paper has been invented for a long time, it has not been able to be used for writing, but now he has seen paper that can write normally.

"Zhicai, how much is this paper worth? How long will it take to make it. After being excited, Guo Jia calmed down and asked.

"Haha, Fengxiao, don't be excited, if this paper is made on a large scale, the price will be cheap, and it is a little more expensive because it is less manufactured, but no matter how expensive it is, it is much cheaper than bamboo slips." Xi Zhicai said.

When Guo Jia heard this, he knew in his heart that this was definitely a great invention.

After Guo Jia was excited, Zhang Yu arranged for the paper mill to be expanded to a market that could supply the entire Han Dynasty in the future.

Zhang Zhao then reported: "Lord, our salt drying method has also achieved great results, the first salt drying is more than 100,000 stones, this efficiency is so high, my subordinates have only seen it in their lives." ”

Speaking of this, Zhang Zhao was also excited.

I didn't expect the results to be so big at one time.

This salt pan can be dried once every two months or so, and if you open a few more salt pans, one county alone can supply the entire Han market.

Throughout history, salt has been one of the most lucrative industries.

In ancient times, this salt was relied on to feed the imperial court.

But in the late Eastern Han Dynasty, it was not the imperial court salt and iron franchise, giving them opportunities.

When Guo Jia heard this, he hurriedly asked what is the salt drying method.

When Guo Jia listened, he was speechless in shock.

"It's shocking that there is such a way in the world, and I'm afraid the entire salt market will be subverted." Guo Jia said in shock.

Zhang Yu is much calmer, and the success of the salt drying method can change the pattern of the entire Han Dynasty, which is not surprising to Zhang Yu.

However, at present, Zhang Yu has not been able to sell salt on a large scale, which will inevitably be counterattacked by salt merchants from all over the country.
