I am the cook, but I am Li Er's son-in-law

The two of them fought for a long time before they stopped, panting slightly, and looked at Yin Xuan.

Yin Xuan smiled slightly, and tapped lightly on the table: "Since you want to learn, then I will teach you."

"But before learning those two interesting things."

"Let's learn something very important first."

The two little girls immediately put on a straight face, serious, and sat down obediently.

"This is a way to make something like 'alkali'." Yin Xuan continued softly, "This is a very important thing."

"This is related to whether gunpowder can go further."

"It is also related to paper making and clothing making."

"Besides, if this thing is manufactured, things like Liuli can be mass-produced."

Liuli!

There was a light in the eyes of the two little girls. This was a very precious thing, but even in their identities, they only had a few colored gadgets in their hands.

No one would dislike such transparent and pure things.

Well. Except for those who can't sell it.

When it comes to Hou's soda-making method, Yin Xuan's eyes are a little sad. The tone of this land has never been the destiny, and it has always been that man will conquer nature.

It is true that the land is vast and abundant, but in key places, some are always missing.

Like grain, there is always not enough to eat. While thinking about how to grow more grain on one piece of land, the industrious Tang people never imagined that in a certain place in the same world, there is another mu of land that can grow several times, Dozens of times the food.

Another example is that Yin Xuan wants to teach them two alkalis.

There is no easily mined trona in this land - which leads to a huge problem, glass, especially soda-lime glass, is almost impossible to appear in this land.

Glass, a small piece.

But it is particularly important for the entire science and technology.

If there is no soda-lime glass, there is no way to step into the microcosm from the macroscopic world, and chemistry will not have any room for development and progress.

There is also no way to explore the distant place—the world beyond the earth, and the opportunity to look forward to the future is lost.

"Alkali" is one of the cornerstones of industry, but there is only one way for Datang to obtain alkali, and that is trade, which has been passed down from the Western Regions.

Hou's soda making method is an extremely great achievement.

The production process is not difficult, but the procedure is a bit complicated, Yin Xuan did not assign it as homework to the two little girls as before.

This thing is not like fireworks.

Even if there is an industrial foundation, it will take nearly ten years to figure it out. Yin Xuan doesn't want to delay it for so long. If ten years is only used to figure out the soda-making method, it will be too long.

From the acquisition of raw materials to the production process, Yin Xuan explained in detail.

As an engineering student, he is no stranger to this kind of stuff.

It's just that the two little girls were a little dizzy when they heard it. A set of materials and a set of procedures are much more complicated than fireworks.

But this is not a matter of one or two days, Yin Xuan did not force them to write down all these things in one day.He can't wait for ten years, but there is no problem with working hard for a few months.

Jiu'er leaned over and listened.

Then he left with a heavy face, but he hadn't listened to them for a while, why couldn't he even understand what they were saying, is this still Chinese?
In addition to outings in the Qingming Festival, for scholars, it is a good day for poetry gatherings.

Focus on the mountains and rivers, feel at ease.

It is probably because they reflect that there is a romantic side in their blood and soul.

Wu Youdao and the others met a lot of new friends at the last hundred-person poetry meeting. This time, they held another poetry meeting outside Chang'an, on the banks of the Bahe River.

You can't stay in Tongfu Restaurant all the time.

That would cost too much money.

Several people boarded the boat and looked around the crowd. One person sighed and said softly, "Brother Wu, didn't you invite the store owner?"

Wu Youdao glanced at him and shook his head: "Why do you invite me here?"

"You know the temper of the shopkeeper. Anyway, please don't move, so I didn't open my mouth to ask for trouble."

"I really hope to see the store make a new chapter." The person sat down and shook his head, "I don't know what spring poems the store can make."

Someone next to him said: "It's not easy for the store to write something."

"Except for the humble room inscription, which was given to others on our own initiative, the other few poems were all begged by us."

Saying that, he paused.

"Although the store owner has a great talent, he is too much like Mr. Wuliu. He never shows off his talent deliberately, but his brilliance is as vast as the sun. If he shows a little bit, it will overwhelm us stars. gone."

Regarding this remark, although some scholars showed a little dissatisfaction on their faces, they did not open their mouths to refute.

Several poems and articles came out, which is the best evidence.

Unless they can come out with an article that surpasses the humble room inscription, the dissatisfaction they show, in the eyes of others, is more like a kind of incompetence to vent.

"It would be great if I could learn from behind the shopkeeper, just like those two girls." One person sighed, and the faces of Li Lizhi and Li Shu appeared in his mind, showing envious expressions.

"They don't learn the classics. Besides arithmetic, there are also some things called physics and chemistry." Someone shook his head. He was one of the few people who showed dissatisfaction on his face just now. , I don’t think anything else is useful.”

He paused for a moment, and emphasized his tone: "Although Ming Suan can be an official, it is still not as good as Ming Jing."

"Besides, although the store owner is good at poetry and poetry, it doesn't prove that he is good at politics."

"Poetry is a small way after all, and governance and security are the great way."

Someone silently spoke after he finished speaking, and spit out a name from his mouth: "Zhou Xiaosan."

The person who spoke just now froze and pursed his lips.

Although it was just a name, the people present knew what he meant.

They often come and go to restaurants, and some people who came later also heard about these things from the mouths of those who came first. Zhou Xiaosan was originally just an unknown bad person, and then he got advice from the store. At that time, he used a bad person, was promoted to a bad handsome, and then became a county lieutenant.

Although this does not prove that the store is proficient in political strategy.

But at least it proved that the store owner is at least not ignorant of political strategy, and has a better level than ordinary people.

"Political strategy, if you just look at it from a distance, it's just talk on paper." Amidst the silence, a person shook his head, "You don't know what to do until you've entered the officialdom."

"I just want to follow the store to learn poetry and count."
