Li Zheng took out some duck eggs from the kitchen and cooked a pot of tea and started cooking tea eggs.

Li Lizhi helped wash duck eggs.

The aroma of tea came out of the pot, and Li Zheng asked, "Have you had morning sickness improved recently?"

Li Lizhi put the washed duck eggs into the pot, "It's much better, it's not as serious as before."

The couple sat by the small stove and whispered.

The maids at home looked at this scene and looked envious.

The couple sat together and seemed to be in love.

If Princess Changle and Chang'an Ling have always had such a good relationship, what else can I ask for in my life?

Li Zheng thought about it and said, "Why do I feel like a daughter?"

Li Lizhi smiled and said, "Everyone wants to have a eldest child, why do you want a daughter?"

Li Zheng thought, "It's good for the eldest daughter to be a daughter, but the sister can easily control her younger brother. We don't just give birth to one."

Li Lizhi twisted the soft flesh around Li Zheng's waist and said, "You still want me to give birth to a few more."

"Give me a few more fun!"

"It's not your birth!"

Li Lizhi stared pretty.

Li Zheng asked in a low voice: "Can Doctor Sun see that it is a boy or a girl?"

The water in the pot was boiling, and the duck eggs rolled in the pot. Li Lizhi looked at the pot, "Who can really tell a boy or a girl from the pulse? Sun Simiao doesn't have this ability, and most of them are lying."

"Reincarnation Paradise"

Li Zhengyu Ruosi nodded, "Whether it is a boy or a girl, our children's living standards cannot be low."

Li Lizhi sat beside Li Zheng and smiled gently.

When the tea eggs were out of the pot, Li Zheng sat in the yard and peeled the tea eggs, and then took out the things to watch.

In the Tiangong chapter on the creation of salt and salt, there are records of industrial salt making methods.

There were also methods of making salt in the Qi people of the Han Dynasty.

But it is not as detailed as recorded in the Ming Dynasty's Tiangong Kaiyu.

In the Ming Dynasty, which had begun to have an industrial scale, the output of salt was much higher.

The biggest output is the development of sea salt.

Nowadays, salt is expensive in the Tang Dynasty, and selling salt is a serious crime.

Although I had told Li Shimin about the way to make fine salt early on.

But the way to make sea salt in this way is not as large as sea salt in terms of output or scale.

If there is no perfect method of extracting sea salt, the sea salt that is exposed is bitter, and there are still many impurities that have not been completely extracted.

During the Ming Dynasty, sea salt was produced on a large scale, and the coastal prosperity was also created before the sea ban.

Li Zheng turned the page and continued to look, recording the method of extracting sea salt from Tiangong Kaiyu, and handed it to Li Zhi, who was about to walk out of the yard.

After taking a roll of drawings handed over by Li Zheng, Li Zhi said curiously: "What is this."

Li Zheng put down the pen in his hand and said, "Your emperor, the King of Wei. His confidante discovered the method of extracting sea salt. From then on, the salt output of the Tang Dynasty can be increased several times. It is really gratifying. The salt price is cheaper, and the people in the world live a better life."

"Yeah?"

Li Zhi looked at the content on the drawings.

Li Zheng said again: "That's true."

Looking at the drawings that were not dry in the moji, Li Zhi sneered: "Haha, it's obviously the drawings you made."

Li Zheng said: "His Royal Highness of Wei was joking. This was clearly painted by His Royal Highness of Wei's confidante."

Li Zhi held the drawing and said, "You are lying to me, but there is no ink on it, it is what you just drew."

Li Zheng said sadly: "The weather has been quite turbulent recently."

"Do you think I'm a fool?"

"Why are you talking so much?"

"snort!"

Li Zhi stomped his feet and left with the drawings. When he came to the academy, he handed the drawings to Li Tai. "Li Zheng said that this was drawn by the emperor's confidante."

Li Tai frowned and looked at the drawings, with many notes on it, "What are these?"

Li Zhi looked at the drawings and said, "This is the way to extract sea salt."

"Sea salt? Isn't sea water bitter?"

"The sea water in the quasi-famous technique is indeed bitter, but Li Zheng said that this is the method of ocean extraction, so it should be that the sea water is inexhaustible, so you can imagine how valuable this drawing is."

Li Zhi whispered.

Li Tai looked at the drawings with satisfaction and patted Li Zhi on the shoulder and said, "You are still smart."

Li Zhi said curiously: "Does the emperor owe to Li Zheng again?"

"Li Zheng is your teacher, he will be your teacher in the future! Don't show off your rudeness."

Li Zhi knew very well that the emperor and Li Zheng were wearing pairs of pants.

But the elder brother is like his father, and Li Zhi couldn't refute Li Tai bowed and said weakly: "Your brother must remember the teachings."

Li Tai said again: "Although Li Zheng is weird, you have grown up in Jingyang since childhood. You must remember Li Zheng's teachings."

"Understood."

Li Tai patted Li Zhi on the shoulder again, "The emperor is not very promising. You must follow Li Zheng to learn skills in the future. This kid must have many skills that he has not taken out. If you can learn more, learn more. This time I really didn't expect that he would have a way to turn sea water into salt."

The sea is vast and the sea water is inexhaustible. If sea water can be used to make salt, the people of the Tang Dynasty will soon get rid of the problem of not being able to afford salt.

This is a blessing.

That's a great thing for all people in the world.

Li Tai's eyes were hot, and the more he looked, the more he felt satisfied. The more he looked, the more he felt that his lifelong affairs had been settled.

Sitting in his room, Li Tai packed up the drawings and planned to present them to his father in a few days.

A woman walked into Li Tai's room and silently placed the food on the table.

Li Tai said to her, "Sit down and eat together."

She stood aside and said restrainedly, "How can the little girl sit with His Highness the King of Wei?"

Looking at her face, Li Tai whispered: "Why are you doing this?"

She smiled and said nothing, and turned around and walked out of the room.

Li Tai chased to the door and said, "I will never let you down in this life!"

She stopped and stood there for a while without looking back.

Under Li Tai's gaze, he accelerated his pace and left again.

When eating the food in front of her, these are the dishes she made by herself.

After finishing the food in front of him, Li Tai hurriedly left the academy and headed towards Chang'an City.

If you dare to face something, you still have to face it. Li Tai came all the way to Chang'an.

It has been three years, and I haven't been to Chang'an City for three years.

After looking at the city walls of Chang'an City for a while, Li Tai stepped forward all the way toward the city gate.

In the palace, Wang Ding hurried to Li Shimin and said, "Your Majesty, the King of Wei is coming down and is now walking towards Chengtian Gate."

Li Shimin whispered: "It's rare that he can come out of the academy in Jingyang."

Wang Ding bowed and said, "Your Majesty, Your Highness, the King of Wei, came alone."

Li Shimin reviewed the memorial and said, "You go to the city gate to welcome him."

"Here!"

After saying that, Li Shimin looked up and said, "By the way, what have Chengqian been doing these days?"
