Tang Dynasty: The beginning of the game is to touch the Princess Changle

"Your Majesty, I have another doubt. Can you please solve it?" Li Shanhuai asked respectfully.

When they came from Chang'an to the manor, they found that the horse hooves would be seriously worn out if the carriages were carrying goods on the cement road.

"Master Li, please tell me if you have any questions!" Li Shimin said proudly.

"Your Majesty, merchants often use horse carriages to carry goods. If horses walk on cement roads, I am afraid that the horse hooves will be worn out even more. I wonder if your Majesty has a good way to solve this problem?"

Li Shanhuai asked carefully and respectfully.

If your Majesty has a way to solve it, it will be fine, but if you can't solve it, it will make the emperor embarrassed!

When Li Shimin heard that this was a problem, he glanced down and found that the boy was not there.

Isn't this a way to show off!

As for those ministers, do they dare to say anything? It's a rebellion!

"Hahaha! I have something to give you, and you can solve this problem!" Li Shimin laughed.

When the heads of the families heard this, they knew that His Majesty really had a solution. "Thank you, Your Majesty. May I ask, what is this thing?"

Li Shimin smiled and glanced at everyone, "You will know if you follow me outside the manor."

When they arrived outside the manor, Li Shimin asked Cheng Yaojin to lift the foot of the horse he was riding. The horse Cheng Yaojin was riding had been nailed with horseshoes.

"Look carefully at the bottom of the horseshoe. The iron piece is called 'horseshoe'. After it is nailed, the horse's hoof will not wear out, and it will not affect the horse's walking and running."

Several heads of the families bent over and took a closer look. They immediately understood the subtleties and praised:

"Your Majesty is wise, this is a magical object!"

Li Shimin nodded calmly, "You can imitate the horseshoe by yourself, and shave the horse's hoof before nailing it."

When the heads of the families heard that the horse's hoof was shaved, could the horse bear it?

"Your Majesty, if you use a knife to cut the horse hoof, if the horse's sole is damaged, wouldn't it be..."

The problem of horse hoof wear is not only caused by the court's war horses, but also by merchants who often replace horses because of damaged hooves.

If the horse hoof is cut with a knife, won't the horse be useless?

"Haha! You don't know that the bottom of the horse's hoof is the horn... layer, which is painless like human nails."

Li Shimin didn't remember the horn, but it didn't stop him from pretending in front of everyone. After Li Shimin received a round of praise, the heads of the families returned to Chang'an.

Their family is swift and decisive, and they will act immediately after making a decision.

Not long after, Li Shimin and others also returned to Chang'an, and Li Tai stayed in the manor.

When he went back, Li Shimin didn't see Su Chen either.

...

"Li Tai, take this and study it, and get it out as soon as possible." Su Chen took out a book and threw it to Li Tai.

It said: Advanced Glass Manufacturing.

The book given to Li Tai this time was also taken directly from the system space without any changes.

Su Chen did not think about how to explain the source of the book, and was even more reluctant to re-copy the books.

Li Tai picked it up and looked through it. Glass? "Su Chen, what is glass?"

Su Chen smiled and said, "You have seen colored glaze, glass is similar to it, and it has a wide range of uses after it is made."

Li Tai nodded as if he understood, and continued to look at the process of glass manufacturing. At the same time, Li Tai had a question in his mind, the seventh grade mathematics that Su Chen gave him last time.

There are often some strange dots in the middle of the text above. Later, he slowly discovered that those dots should be used for punctuation.

There are more dots on this book, and he is now used to punctuating sentences based on those dots.

"What? This glass is actually made of sand?" Li Tai stood up and shouted.

"Don't be excited, it is made of sand, and the colored glaze you are talking about is also made of sand." Su Chen raised his hand to signal Li Tai to sit down.

To be precise, not just any sand can be fired into glass. The selected sand must contain various metal oxides such as sodium, calcium, magnesium, and aluminum.

After being fired at high temperature and melted together, glass is finally formed.

Li Tai felt sick. He was not very clear about glass, but he knew about colored glaze.

The price was so high that it was terribly expensive. It was priced at one hundred taels of gold. Colored glaze was rare on the market, so people scrambled to buy it.

Only those wealthy families bought it as a treasure of the family, and the palace also had colored glaze.

Moreover, most of the colored glaze came from merchants outside the region. Now he found that the colored glaze was made of sand.

"Study it carefully. The quartz sand mentioned in the book is a very good raw material. You just need to try it a few more times."

This advanced version of glass manufacturing was a reward given by the system yesterday because the cement road was repaired.

The "travel" in the side quest was completed.

Su Chen thought that the crops were about to be harvested, there were 1,000 pigs being raised, and part of the red brick house had been built. The side quests improved the "food, clothing, housing and transportation", and the only thing missing was clothes.

I just wanted to see if I couldCotton cannot be found, but the places with cotton now do not belong to the Tang Dynasty.

Su Chen drew a picture of cotton and asked the servants to keep an eye out in Chang'an City.

...

"My Lord, the noble family has arranged more than 300 people to come to the manor, saying that they are learning to make cement and red bricks, and some are learning to keep accounts." Zhang Long hurried to the living room to report to Su Chen.

"Okay, you ask Chang Sun Chong to arrange them, and also see if there are any literate people among the more than 150 people who are training with you. Arrange those who can read to learn lowercase numbers." Su Chen planned to make them foremen.

These people were arranged here by Li Shimin, and no one has been taking care of them. They can only be regarded as guards of the manor now.

As for the more than 500 guards outside, Su Chen has rarely seen them.

"Yes, my Lord!" Zhang Long turned and left.

"You study slowly, I'm leaving first!" Su Chen stood up and said to Li Tai.

Li Tai ignored Su Chen. He was now immersed in the glass making. He learned from the book that this glass can be made into various shapes.

Moreover, this glass can be used to replace window paper, which can block wind and rain and transmit light.

Su Chen looked at Li Tai who was already fascinated, smiled and shook his head, thinking: "It's good that you like to study. There will be many things for you to study in a while."

Originally planned to let Li Tai make paper and compile books, but thought that it was not the right time now. As the saying goes:

'When the granaries are full, people know etiquette, and when they have enough food and clothing, they know honor and disgrace'.

The meaning of this sentence is very simple. Only when the people have enough food and clothing will they think about paying attention to etiquette and learning knowledge.

Only when we solve the problem of food and clothing first can we plan for the future development.

But it will be soon. Sweet potatoes and potatoes are planted twice a year. These two high-yield grains can temporarily solve the food shortage.

The first season is planted from March to May, and the second season is planted from July to September.

Now it is only four or five days away from mid-July, and Su Chen is planning to gather the villagers to harvest those sweet potatoes and potatoes.

Su Chen has a plan for this batch of sweet potatoes and potatoes.

If the disaster victims in Shanxi come to Chang'an, they will all join in the road construction. When the road is completed, they can return to their hometown in Shanxi.

At the same time, some sweet potatoes and potatoes will be given to them for planting, and there is no need to worry that the people will eat the seeds.

They are all paid for participating in the road construction, and they are guaranteed two meals a day. Even women and children are paid, and they can be responsible for cooking for the construction team.
