Wang Zheng smiled and shook his head, "Just think of it as supporting these craftsmen and send some to the potters.

Pass on the technology of firing ceramic pieces to him, and let him make some ceramic knives. We don’t have that many iron tools, so we can use ceramic ones instead.”

Salt and iron are monopolized by the imperial court. If Wang Zheng can still get some salt for his own use, as for iron, Wang Zheng now dares not even touch it.

It is naturally impossible to directly fire the ceramic knives of later generations, but as long as we can fire a ceramic knife with sufficient hardness, we can sharpen it if it is not sharp. As long as it can achieve the effect of cutting meat, it will be fine.

Wang was about to go back when Chen Laowu, who raised fish, ran over and asked Wang what kind of fish he planned to raise.

"What do you think?"

"If it's in a large reservoir, you can raise anything you want. Since the area is big, you can just plant as many fish fry as you can. As long as you feed them diligently, you don't have to worry about not getting any harvest.

“Why not raise grass carp?”

When the fisherman saw that the person asking the question was a little kid, he immediately pointed to the distance and said enthusiastically, "Yes, it will take more than a day to get to Longzhou. You can take the official ship over there. Although it is more expensive, it is also safe."

Chen Laowu nodded and said, "That's fine. I think the grass carp fry should grow faster with grass juice. If they can grow into rice seedlings and are an inch long by the time the forest is closed, they can go to the fields and eat aquatic plants.

“I see.”

Of course, every time walnuts are sold, there will be bargaining and performances of reluctance, plus a lot of nonsense like "they were stolen from my grandfather" and "I will never sell them if I don't have enough money", before the deal is finally reached.

After watching Chen Laowu leave happily, Zhang San asked, "Does the master want to send him to Jinli Beach?"

"Thank you, Steward. I will do my best."

Chen Laowu said thoughtfully: "I don't know, but we can give it a try. It's just that it's a bit troublesome to make grass pulp. It's okay at the beginning, but as the grass carp grows up little by little, it will definitely need a lot of grass pulp."

Wang Zheng thought for a while and asked, "What do you think? If we beat the grass into grass pulp and put it into the water, will the grass carp fry have something to eat and grow faster?"

Wang Ying is now dressed in men's clothes, while Wang Wu has not changed much, except that his clothes are a little more luxurious.

"No matter how many fry we get here, it's not convenient to distribute them. It's much more convenient to transport them from Koi Beach. After all, most of our subordinate farms are on both sides of the Yushui River."

Originally, Wang Ying was much more eloquent than Wang Wu. After running all the way, Wang Ying was a little timid at the beginning. But when Wang Ying exchanged two salted walnuts and a large mule for a good horse for the first time, Wang Ying's courage immediately grew.

In just two days, Wang Ying sold more than ten pairs of walnuts. Although the prices varied, they were all above two taels of silver. With the money, Wang Ying bought a good horse, which speeded up his journey a lot.

“Why do grass carps grow slowly when they are young?”

The next day, when Wang was teaching others how to grow sugarcane, the siblings Wang Ying and Wang Wu had already passed Hanzhong and arrived at the Yu River.

If it is in a rice field, it is best to raise carp and crucian carp. I heard that the imperial court now allows people to eat carp. Carp can eat insects in the water, and crucian carp grows fast and reproduces quickly and in large numbers. "

"Grass carp grow slowly when they are young. The fry that are bred now cannot eat the aquatic plants when they are released into the fields. When they can eat the aquatic plants next year, they will eat the rice seedlings as well."

The big mule that the brother and sister had ridden earlier had been exchanged by Wang Ying for two big horses using salted walnuts. After running more than a thousand miles in just a few days, although the two were exhausted, their riding skills had improved a lot.

"Then go find some breeding fish. Once we have the breeding fish ready, we will send you to another place to build a bigger fish fry pond. We need a lot of fish fry. Don't worry, I will double your wages for the business trip, and you will get a reward if you do a good job."

So many royal farms? Wang Ying was surprised. After thinking for a while, he took out a few coins and threw them to the boatman. He continued to ask, "Why did I hear that there is only one royal farm? You are not lying to me, are you?"

Chen Laowu shook his head and said, "I don't know. Maybe he couldn't eat grass when he was a kid."

The boatman took a look at Wang Ying's clothes and immediately replied respectfully, "There are many royal farms along the Yu River now. I wonder which one you are asking about?"

The moment they saw Yu Shui, they immediately became alert and at the same time felt as if they had survived a disaster, as if all the fatigue in their bodies had been swept away.

By then, we can go to the fields with grass carp and carp together, and we can get rid of weeds and insects. I think we can also harvest more rice. Grass carp eat a lot and poop a lot, which can fertilize the fields."

Zhang San beside him smiled and said to Chen Laowu with confidence: "Just do as the master says. When the time comes, just come to me for how much straw syrup you need."

After getting on the boat, Wang Ying took out another pair of walnuts, turning them in his hands while walking with a step that showed no regard for his relatives. When he saw a boatman, Wang Ying immediately grabbed him and asked him about his affairs.

Walnuts that cost a penny a few times become valuable once cooked with some fatty pork and fermented black beans. People outside are actually the same as those in the village and are just as easy to fool. This is how Wang Ying feels.

After that, although Wang Ying still rushed to travel every day, every time he ate, stayed in a hotel, rested, or drank tea, he would turn a pair of shiny walnuts in his hands. If someone asked about the price, Wang Ying would sell them immediately.

Riding his horse to the dock, Wang Ying asked a middle-aged fisherman, "Uncle, can we take a boat from here to Longzhou?"

"Do you know there is a royal farm near the Yu River?"

The boatman took the money and said in a more respectful manner, "I dare not deceive you, young master. In the first half of last year, there was indeed only one royal farm near Yushui, but suddenly many appeared in the second half."

"That's the royal farm from the first half of the year. Do you know where it is?"

The boatman nodded and said, "I know. We will reach the Royal Farm after feeding tomorrow. But I heard that something happened to the Royal Farm. I heard that they moved or something."

"Moving? Where did you move to?"

"I don't know either. This is news that just arrived today. I only heard a little bit. But even if we are moving, it will take more than a short time to move such a large place."
