There are more than ten large iron pots connected together on the ground stove. The fire is burned at one end, and the chimney is set at the other end, which will pull the fire over there.

Although the long iron shovel can only place the coal under the third large iron pot, the chimney pulls the fire, and the first five or six large iron pots will still be burned by the open flame. The temperature is still quite high, and most of the brine will evaporate here.

Then others used a large wooden ladle to scoop the brine from the first large iron pot to the sixth large iron pot. The brine had become very viscous.

Although the temperature of the large iron pots at the back will gradually decrease, water can still continue to evaporate. By the time the viscous brine reaches the tenth large iron pot, it has almost turned into fine green salt.

After being baked in the final few large iron pots, the final green salt can be directly packed into bamboo tubes for transportation.

A bamboo tube of high-quality green salt costs thirty cents per pound and is only sold in internal farms.

Wang Xiao did not intend to collect any taxes from the subordinate farms, and would even spend money to purchase their various agricultural products.

“When the chief steward first organized subordinate farms, there were nearly 100,000 people at the time, and the number has been increasing every month since then. When the information was distributed this year, the number was close to 200,000.

At the same time, we will announce to the public that we are collecting wet millet, and the price will be set at one penny per bushel.

Supporting a little kid is nothing at all, but having this little kid has many benefits. Not only can you buy cheap daily necessities, but you can also learn all kinds of knowledge and experience, and you can also be protected by Wang Zheng.

The impeachment memorials from the nearby counties and prefectures are floating towards Chang'an like snowflakes. How long do you think His Majesty and His Majesty can tolerate you?"

Not only have the Lao Ba people joined, but Han people have also been joining the various farms in large numbers. If this continues, the population may reach one million by the end of this year.

"The Ba people have come out in large numbers. If we want to completely assimilate them, we must have a large number of Han people join them to offset their numerical advantage. In my opinion, the Han people should not have slaves."

You go to Yuzhou in person and discuss with Zhangsun Wuji. If other counties and prefectures need it, we can also send people to collect wet millet, but we need the government to provide a guarantee, and we can buy it on credit first, and then settle the bill together in the end."

After the raw materials were distributed, the number of people increased sharply again. By the time the salt was sold, it was close to 300,000, and now it is close to 400,000.

Not long after that, Li Jingye came to Wang Zheng. Wang Zheng was too lazy to see him. He just asked Chen Fengning to tell his people to learn from Wu Yi and the other kids and stop thinking about making money all the time.

"But the great steward has been accepting Han people endlessly, causing population loss in other counties and prefectures, and most of them are escaped slaves. Isn't this against Tang law?"

Looking at the drizzle still falling outside, Wang Zheng sighed and said to Chen Fengning, "Send someone to deliver the ground stoves to the subordinate farms.

When these people first went down, they were somewhat bossy, as if they really thought of themselves as the managers of the farms, and they often gave orders to the people on the subordinate farms.

Facing Chen Fengning's question, Wang Zheng smiled, nodded and said, "No matter where the population flows to, they are all your Majesty's people. Although they do not pay taxes, they are also creating wealth for your Majesty, just in different ways."

I am the boss of Shuzhong Farm, you just need to follow my orders, if there is anything, I will take responsibility, it is not Li Jingye's turn to make decisions, otherwise, you can go ask Li Jingye now to see what his rules are?"

In this case, the steward did this, and the common people were happy, but the queen might hold the steward accountable, and Li Jingye would probably not agree with the steward's decision."

Slave, Wang Zheng couldn't help but smile bitterly, because he himself was also a royal slave.

The old Ba people were willing to come out of the mountains and integrate into the Han family. In Li Zhi's view, this was a good thing.

In Wang Zheng's opinion, true national integration should be achieved by luring people with benefits. Only when people are willing to live with you can it be considered national integration. If it causes bloodshed, it is naked invasion.

However, they had to buy the various supplies that Wang Zheng provided them, such as cloth and salt, with their own money. Of course, the price would be lower than the market price.

Someone wrote to Wang Zheng to ask for his advice, and Wang Zheng’s reply was, just pretend they don’t exist, and if you don’t like them, you can beat them three times a day, but you can’t beat them to death or cripple them.

Chen Fengning hesitated for a moment, and said with a worried look on his face: "We may lose money if we do this. Dry rice is only three or five cents a bushel. We spend a lot of effort, but in the end it may not be worth it to collect dry rice.

Wang Zheng looked at Chen Fengning with a half-smile, "You think too much. The queen is not that stingy about a few money and grain. As for Li Jingye, just pretend he doesn't exist.

This was Wang Zheng's method of attracting the old Ba people who made a living by hunting in the mountains to come and submit to him. This was done with the consent of Wu Zetian. As long as Wang Zheng could send a lot of money and grain to Chang'an every year, Li Zhi and Wu Zetian would not care about these trivial matters.

Wang Zheng adopted a laissez-faire attitude towards the subordinate farms of Huangzhuang. The kids like Wu Yi he sent there were only to do record-keeping work, and usually passed on the knowledge and experience they learned from Wang Zheng.

Wu Yi and his companions only make suggestions and never help the people on the farm to make decisions. This is the fundamental reason why the Ba people support Wu Yi. To those Ba people, Wu Yi and his companions are almost like gods.

The main thing is that the imperial court is not short of food now, and the only areas affected by the disaster are Yuzhou and some nearby counties. Generally speaking, there is no shortage of food this year. Moreover, we have so many vermicelli, not only will we not lack food, we will even have a lot of surplus.

Thinking of this, Wang Zheng couldn't help but envy the Qing Dynasty. That was an era that took pride in being a slave. Being a royal slave was an honor, and ordinary people were not qualified to call themselves slaves.

After hearing Wang Zheng’s last words, Chen Fengning didn’t know what he was thinking about. He fell silent for a moment. Finally, he bowed to Wang Zheng and turned away.

After the news that the royal farm was collecting wet millet spread, people kept sending wet millet over. At first, it was only people from the surrounding areas of the farm, but gradually large ships began to transport large quantities of wet millet.

The heavy rain finally stopped after half a month. Most of the rice in the fields had been harvested, and only some rice in the fields on the slopes remained.

Wang Zheng could only smile bitterly as he looked at the salt-making workshop filled with people sitting around. The main task this year was to process the millet.
