Datang: Acting as a celestial mystery at the beginning

Li Shimin looked at Changsun Wugou worriedly, and the two looked at each other, and they could see the concern in each other's eyes.

His two sons both have the appearance of emperors, and I am afraid that there will be a fight in the future, just like him and Li Jiancheng.

This is not what Li Shimin wants to see.

"I'm just talking nonsense about today's matter. Only you and I know it. If it gets out, it won't be good for us." Li Yi'an added.

"Of course I know."

Li Shimin nodded and said, but his heart was in a mess again, and he reluctantly put all kinds of thoughts behind him.

Li Yi'an continued: "Madam's body is suffering from an old disease, and after ten years, her life will be in danger..."

"what!"

Li Shimin said nervously: "Sir, do your calculations more clearly! You must have made a mistake."

He believed in the young man in front of him completely. Hearing these words, his heart was lifted.

"Erlang, I can accompany you for another ten years. I am satisfied. I won't force anything else."

The eldest grandson Wugou was quite open-minded, as if he didn't care about life and death.

"Don't worry, I haven't finished my words yet."

Li Yi'an shook his head and said: "In three years, Madam's old illness will turn around. If you seize the opportunity, you will be safe and sound. If you can't..."

He didn't need to finish the following words, Li Shimin knew the result.

"What is a turnaround?"

Li Shimin asked nervously.

Li Yi'an pointed to the sky and said, "The secrets of heaven must not be revealed."

It's not that he doesn't want to say it, but that he really can't figure it out.

The template of Tianji Shensuan is about to reach its full level, and he can calculate more things, but it is not omnipotent, and some things are still difficult to calculate.

Even, vaguely, he felt that this turning point was himself.

"Okay, Mister has done his best, Erlang doesn't need to force it."

Changsun Wugou shook her head slightly, and she signaled to Li Junxian to give Li Yi'an today's reward.

Of course Li Yi'an was not polite to her and accepted it graciously.

"Today, thank you sir for solving my problems."

Li Shimin said gratefully.

Apart from other things, he is very fond of the words Qiangu Yidi.

Li Yi'an cupped his hands as a return gift.

"Sir, you have guests here!"

At this time, outside the gate, a servant walked in, one of the two who helped Li Yi'an raise pigs, and said: "Sir, we have slaughtered, it really doesn't have that kind of smell, and the meat is also distributed to nearby pigs." People, I left this specially for Mr.

He carried a heavy piece of meat and put it on the table next to him, it was the pork of those Rongchang pigs.

"Thank you for your hard work!"

Li Yi'an said: "Mr., it's noon in the blink of an eye. You must be hungry too. I happen to have some meat. Why don't you stay and have a light meal before going back?"

"Then interrupt!"

Li Shimin nodded in agreement, before coming, he had heard that the husband was very hospitable.

He also wanted to take this opportunity to get closer to Li Yi'an so that he could win over Li Yi'an in the future.

"Please come in!"

Li Yian invited people to the main hall.

This hall runs through the front and back yards.

Li Shimin followed him in and opened their mouths in surprise when they saw the scene in the backyard.

Because they were in the backyard and saw a green vegetable field.

In this season, mid-autumn has passed, and it is beginning to enter the season of autumn. It is not far from winter, and there are gusts of cool wind blowing.

In the north, at the turn of mid-season and autumn, even green leaves are seldom seen. Many people store their own meat and vegetables in the cellar for the winter.

Why here, there is still a scene of spring.

Soon, they discovered that there was a large shed in the backyard, which was made of transparent pieces, covering the vegetable field in the backyard.

"Sir, what are those...?"

Li Shimin pointed to the shed in surprise and asked curiously.

"This is called a greenhouse. It is mainly used to keep crops warm. It can be planted even in winter. It will be winter in a month and the weather will get cold. I will find someone to build it in advance to save trouble in the future."

Li Yi'an knew they would be shocked, and introduced: "The transparent thing is called Liuli."

These toys are things he has tossed out before. He can't make plastic, but can only make glass to build a greenhouse, and he spent a lot of money.

However, Li Shimin was shocked again.

"Tell me, those are colored glazes!"

So many excellent quality, clear and transparent glazes!

Chapter 11 The Hidden Master

The ancient glass making process can be traced back to lead-barium glass in the late Spring and Autumn Period. The first glass products were used instead of jade. Glass ornaments were unearthed from the tomb of the Nanyue king in the Western Han Dynasty.

The term Liuli was proposed by Huan Kuan in the Western Han Dynasty in "On Salt and Iron", and it was used until the Ming Dynasty.

Liuli was extremely precious in the Tang Dynasty, and ordinary people couldn't afford it at all, and it was rare even among aristocratic families.

The local glass production technology in the Central Plains is immature. After the emergence of the Silk Road, although it can be imported from foreign countries, it is a long way from the Western Regions to the Central Plains. Expensive, rare, and mostly impurities.

Li Shimin has never seen such a clear and transparent colored glaze, which would cost sky-high prices to take out a piece casually, yet it was actually used by Li Yi'an like this.

How rich is that?
