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

Zhou Xiaosan is indeed a smart person.

Yin Xuan's words woke him up immediately, no wonder I always felt like I had neglected something during this time, no wonder I felt like I was being left out during this time.

It turned out to be so.
Zhou Xiaosan bowed to Yin Xuan again and cupped his hands.

These things seem very simple, but simplicity does not mean that they can be figured out. Without Yin Xuan's guidance, Zhou Xiaosan felt that it might take him several years to figure it out.

Yin Xuan waved his hand and smiled slightly: "Don't worry about using bad people boldly."

"They are the most humble people."

"There are still twelve guards in Chang'an City."

"This group of bad people, unless they really get together and really start waving their knives at someone, unless...you are not the same person as them." Yin Xuan sighed and waved his hand , shaking his head, "They don't realize how powerful this group of people is."

When a group of people play under a default rule and use this rule for a long time, they will subconsciously think that this rule is the truth between heaven and earth.

would assume that everyone would follow this rule.

And under this rule, the creature at the bottom of the rule chain became the object they looked down on the most.

When this group of people is content with the status quo and does not resist, or after resisting, they are still dealt with by this rule, and they will contemptuously think that this group of people is fish and meat at the mercy of slaughter.

They never imagined what kind of power would erupt if this group of people broke the rules.

Just like Sima Yao in the Eastern Jin Dynasty.

He may have thought that he would die in the war, that he would die of old age or illness, but he never thought that he would die at the hands of a palace lady in the end.

Zhou Xiaosan nodded, remembering Yin Xuan's words in his heart.

This conversation with Yin Xuan made him feel a lot better, the restless feeling disappeared a lot, and he has more confidence in the future.

After filling a gourd of Jade Jingqiu, Zhou Xiaosan resigned and left.

Yin Xuan also tidied up, closed the door, turned around and went back to his home - Yin Lulu, Jiu'er and Wang Shi had already gone back, after dinner.

As soon as Zhou Xiaosan left Huaizhen Square, the curfew came.

But he didn't panic, and still walked slowly towards the county government office. Now his identity is different from before, and even because of his own reasons, he is even more free than some officials of the fifth and sixth ranks in terms of curfew.

After returning to the county office, he began to think about how to make himself behave more like a group of officials.

And at this moment, in the imperial city.

Li Lizhi and Li Shu, with dusty faces, looked helplessly at several ceramic vessels on the table in the garden—now this garden has become their testing ground.

Concubine Yang acted coquettishly in front of Li Shimin, but it was useless. Compared to Concubine Yang's coquettishness, Li Shimin would rather see something else born in the hands of his two daughters.

He had long wanted to build a palace.

But because of Wei Zheng, he raised it many times and was scolded back many times.

Now that the garden is being overwhelmed by the two daughters, and the relationship with Li Yuan has eased, it is possible to openly propose to build a new summer palace in the upper right corner of the imperial city.

Except for Wei Zheng's objection, the other people's objection was not very loud.

After all, building a summer palace for his father—although everyone knew what Li Shimin was thinking, at least it was an act of filial piety on the surface.

Your Majesty's acts of filial piety can be regarded as making up for the lack of personal virtue.

The Yong'an Palace, or the Daming Palace, began to be built under the preparations of the Shaofu Supervisor and the Ministry of Industry.

The garden was completely divided between the two little girls, and they became even more unscrupulous.

The eunuchs and maids were very puzzled, where did the two princesses come up with such strange ways to harm the garden, and of course they were even more puzzled that His Majesty was so happy to see the two princesses doing such harm.
After getting Hou's alkali-making method, he couldn't wait to greet the eunuchs and maids, and built earthen kilns and some necessary utensils in the wreath.

This is their third test tonight.

It was also their third experiment since this period of time.

It's not to say how complicated this experiment is, but the preparatory work in the early stage is really complicated.For example, those utensils used for experiments.

Yin Xuan said that it is best to use pure and transparent colored glaze, but the problem is that they don't have any. Adding up the colored glaze in the entire imperial city, they can't make a set of usable utensils.

The soda making method they are studying now is to make colored glaze in the future, but in order to implement this soda making method, they need colored glaze products.

Seems to be stuck in an endless loop.

But what clever people they are, the police made a set of ceramic utensils.

Then we have to prepare sodium chloride—the name of this thing seems a little daunting, and the two little girls were a little bit drumming at first.

But in fact, this thing is very common. The two of them went to Shangshi Bureau and got a can of this thing.Sodium chloride is actually salt.

The most difficult thing to get is ammonia gas.

Of course, there is an industrial manufacturing method for this thing, but there is no way to use it with Datang's existing technical means, so Yin Xuan gave them an idea.

As one of the necessary elements for the growth of plants and animals in nature, it can of course be obtained from plants and animals.

A certain amount of ammonia gas is contained in the fermentation of animal manure.

This made the two little girls sick for a while.

They are very strange, why these things are always involved with gold juice and feces, last time the phosphorus was like this, and this ammonia gas was also like this
But anyway, they didn't do it by themselves. They were so sick that they couldn't eat much for a day, so they asked the eunuch to prepare some, put them in a wooden barrel, and let it ferment.

Sodium chloride is dissolved in water, then ammonia gas is introduced, and then carbon dioxide is introduced, which is relatively easy to obtain, and carbon dioxide will be obtained by burning charcoal.

They also remembered what Yin Xuan said, the charcoal must be fully burned, otherwise it is easy to get carbon monoxide instead of carbon dioxide.

If all goes well, in this pure, transparent liquid, you will get a certain amount of white powdery crystals.

In fact, the experiment was simpler than they thought.

They were prepared to fail many times, but just for the third time, they had succeeded in obtaining some white powdery crystals.

After heating through ceramics, they got the final product they wanted, sodium carbonate, which is soda ash.
