China's history of using seawater to make salt is very early, and it can be traced back to the period of the Three Sovereigns and Five Emperors. But strangely, the history of salt drying is very short. The real salt drying method did not appear until the Song Dynasty. People used salt boiling method to burn sea water with firewood to obtain the coarse grain sea salt needed.

As for coarse salt, edible salt can be produced through secondary processing, dissolution, filtration, impurities removal, carbon filtration and other processes.

Of course, it is incomparable to modern salt.

But in this era, those are already considered good salt.

"How to dry salt?" Lu Zhi asked.

"It's very simple. Dig a pool, put it in the sea water and let the sun steam it. The sea water in the first-level pool is dry for one day, put it in the second-level pool, and so on. After passing through 9 pools in a row, the sea water becomes brine. When placed in the tenth pool, the sea water will condense and crystallized salt will appear. Now you can start harvesting." Jiang Hao said.

Lu Zhi's eyes widened, "It's that simple?"

"It's not complicated at all, but no one knows this method." Jiang Hao smiled.

"But what if it rains? Isn't it white or not?" Lu Zhi asked.

"Indeed, we need to choose a good weather when the weather is good. Of course, sometimes it may not be good for more than ten consecutive days. If it rains heavily, we can put the next few brines into the brine pool in advance and seal them out when the weather is good. This will save a lot of trouble. However, drying salt is a job to look at the weather." Jiang Hao said.

"That's better to cook salt." Lu Zhi felt that it was not very safe and could easily fail.

Jiang Hao shook his head, "But do you know that if the output of salt drying is done, it will be hundreds and thousands of times the output of boiling salt, and there is no need to consume too much manpower. More importantly, there is no need to use a lot of firewood, which is green and environmentally friendly."

"Environmental friendly?"

“Yes, environmentally friendly.”

“Is environmental protection important?”

Jiang Hao's face became very serious and said, "Environmental protection is very, very, very, very, very, very, very, very, very important!!!"

Lu Zhi was shocked by Jiang Hao's long list of environmental protection, and nodded in horror, "Yeah, yes, I know, environmental protection is very important, what should I do?"

"You call a group of people over, just 500 people. I will guide them to build a salt-drying pond here." Jiang Hao said.

"But Mr. Lang, why should we spend so much time here?" Lu Zhi asked.

"Little fool, isn't it good to give this industry to my father-in-law? This is a huge business that can make the Lu family rich in the future. The porcelain kiln will be too small after all, and the government will also manufacture a large amount of porcelain in the future. This Yantian business will be regarded as a betrothal gift for my father-in-law. Who told me that someone was greedy and wanted two daughters who are as beautiful as a flower, beautiful as a charming, smart, caring and capable as well. I don't give more betrothal gifts, and I feel guilty." Jiang Hao opened his mouth and said a lot of sweet words.

Lu Zhi's heart was about to fly, and she looked at Jiang Hao, and countless peach hearts were sprayed out from it.

"Mr. Xie loves Zhier and Su Su so much." Lu Zhi said softly.

Jiang Hao reached out to pinch Lu Zhi's cheek and said with a smile: "There is no way. Who told me that someone was guilty? I was scolded for being fickle all night. I was afraid that my little secretary would be angry."

Lu Zhi smiled sweetly, "Zhi'er is just a little bitch. She won't be really angry, and she won't dare to be angry with her husband."

But then Lu Zhi's little face showed a slightly sad expression. He looked at Jiang Hao's weak eyes and said, "I know that my husband loves Ji'er and Su Su, but we are just concubines after all. I only hope that my husband will not dislike our sisters in the future and abandon them at will."

Jiang Hao frowned slightly, "How is it possible? Zhi'er is thinking too much."

Jiang Hao knew that this was Lu Zhi’s biggest worry. When Jiang Hao and the Lu family first came into contact, Lu Gong asked Jiang Hao if he had a family. Jiang Hao said that he had already gotten engaged. Later, Lu Gong gave Lu Zhi to Jiang Hao as a concubine and climbed up to his big tree.

Now Su Su also followed Jiang Hao. Although she had no bridal chamber, she was already his concubine in name.

However, the status of concubines in ancient times was very low. In ancient China, it was always monogamous and continued to the modern era. As for concubines, they were not men's wives at all. They were just tools of indulgence, and some of them could be bought and sold and abandoned at will. Only after giving birth can the status of children be improved due to their existence.

Jiang Hao even felt that the ancient concubine system was a system that was inhumane, cruel and ruthless, and was not as good as the system of some countries in which four wives were acquired. At least those wives were legal and had the same status.

Jiang Hao held Lu Zhi in his arms and put his mouth in her ear and whispered: "After we go out and have peace, the husband will announce the complete abolition of the concubine system and change it to polygamy. Each man can only take up four wives at most. If the quota of four wives is used up, he will not be allowed to take them again for life."

Lu Zhi was shocked.

She is extremely smart, and she heard a lot from Jiang Hao's words.

Announced the abolition of the concubine system and changed to polygamy system.

Who has this right? I am afraid that only the king of a country has this right.

She had had countless guesses before. Now when she heard Jiang Hao express this meaning, she felt that her previous guess was probably true. Lang Jun’s heart was very big, very big.

She thought again, if the husband becomes the king and the system is changed, then she will be the wife. This is great news for her, and in this way, she will be the queen.

A smile that could not be concealed on Lu Zhi's face.

Jiang Hao let go of her, looked at Lu Zhi with a silly smile, and flicked her smooth forehead, "Don't smile foolishly, there are many things you have to do in the future, all of this is for us to plan for the future, do you know?"

"Zhi'er knows that Zhi'er will be more and more...work hard." Lü Zhi said with a smile.

Just now, Lu Zhi had already regarded what Jiang Hao said as the highest goal in the future. She would work hard for that goal. Whoever dared to stop her will kill anyone, hehe.

Jiang Hao bounced her forehead again, "Dare to imitate me and be careful to become a stutter."

The two of them laughed and joking in the car.

After the two of them finished their fight, Lu Zhi looked at Jiang Hao and suddenly asked, "Wangjun, why are there four?"

“What four?”

"Why did the Langjun stipulate that he should choose up to four wives, Su Su, and the Princess Yu Shu whom I had never met, and there were only three. Does Langjun have any other candidates?"

Jiang Hao carried Lu Zhi to his thighs and pulled his butt.

No reason to find, spank.

......

Time flies, and everything goes very smoothly. Although there are many things, when Jiang Hao mercies everything and arranges the right subordinates to do things, all parties make great progress.

The county magistrate of Donghai received the order from Jiang Hao and did not dare to neglect it. He recruited five or six hundred crew members in one month to send it. Cao Shen arranged all these people on the 30 building ships that had been built and began to train the ships.

After the shipyard built the ten tower ships, it stopped building the tower ships. Now more than 6,000 craftsmen have begun to make all their efforts in building treasure ships and tooth ships.

Xiao He also sent a group of people, including hundreds of crew members, more of them female slaves and orphans. The first time he sent them to see Jiang Hao, Xiao He came to see more than 2,000 female slaves, and more than 1,000 orphans, and perhaps more in the future.

Jiang Hao calculated based on the number of ships. He could bring 670,000 people with him after the amount of materials. Now he has 6,000 troops, more than 6,000 craftsmen, more than 3,000 slaves, and about 5,000 crew members. Jiang Hao counted all the craftsmen in the shipyard. He would definitely bring a large number of these people, and he could also build ships outside in the future.

After doing this, I was looking for 20,000 female slaves, and 20,000 orphans were almost the same.

After saying this, Xiao He told Jiang Hao a message, "My lord, I just got the news. Not long ago, the First Emperor announced to the world and officially appointed Fusu Prince as the crown prince. At the same time, he issued an order to let Fusu Prince participate in some government affairs. Now Fusu Prince has rushed from the northern border to Xianyang, and probably hasn't arrived yet."

Jiang Hao was stunned when he heard this news.

Fusu was made the crown prince.

He also asked him to participate in politics.

This has never happened in history. Why did Qin Shihuang not establish a crown prince? In fact, this is also his selfish intention. Establishing a crown prince means that he is unwilling to admit that he will die in future generations, but he did not expect that he would die so early and so suddenly in the end.

In fact, when Qin Shihuang fell ill and realized that he was about to die, he had already made many arrangements, such as asking the convoy to rush to the northern border to meet Fusu, and finally wrote an edict to pass the throne, but he never expected that Zhao Gao would ruin the Ying family's territory in the end.

It is said that Qin Shihuang doesn't like his eldest son, and he says he is weak and believes in Confucianism. Fusu still opposes him everywhere, but in Qin Shihuang's heart, he always believes that his eldest son Fusu is the best candidate to inherit the throne.

Sending Fusu to the frontier and staying with Meng Tian, ​​who has the 300,000 army, is actually a kind of protection. Who can move Fusu under the protection of the 300,000 army?

But what happened later had a series of dramatic changes. Zhao Gao falsely passed the imperial edict and asked Fusu to commit suicide. Meng Tian stopped him, but Fusu still stubbornly swung his sword and committed suicide, and Meng Tian was just helpless.

Now Fusu is made the crown prince and returns to Xianyang to participate in government affairs. This will ensure Fusu's status at once, and others may be unable to shake it anymore.

It seems that Emperor First Emperor has made a decision to let the country enter a state of recuperation. For a stable country, Fusu is indeed the best candidate.

However, Fusu has always liked Confucianism and did not know what impact it would have on the development of Taoism. Jiang Hao thought about it and suddenly smiled slightly. If the development of a sect is too smooth, it will quickly become bloated and arrogant, and even become domineering.

If someone beats me, he may be able to better recognize himself and become more adaptable to society. He is ready to leave, and the Holy See also handed over to the First Emperor. As for what he will do in the future, it depends on his development.

The broken words are broken, the broken shadows of glass, the late autumn wind, why do you have to take joy and sorrow by yourself? People must learn to grow up by themselves and learn to face all hardships and twists and turns.

The same applies to a sect.

Another month passed in a blink of an eye.

The 30 large ships have been prepared, the crew is skillful in handling, and the supplies are ready. The time is also in September. Jiang Hao said to Lu Zhi: "Zhi'er, everything is ready. Your husband is ready to set off for Goguryeo. You can take care of your family."

Lu Zhi nodded, "I wish you all the best and bring your sister Yu Shu back as soon as possible."

Jiang Hao smiled, "How did you know it's a sister?"

"It's my sister late at night," Lu Zhi said with a sly smile.
