My zoo is connected to the Tang Dynasty

Li Shimin returned to the East Palace, still holding a black charcoal in his hand, followed by his two daughters.

"The Mother ......"

As soon as Li Lizhi answered the East Palace, she rushed towards the place where the eldest grandson Wujian was, she was holding a box of incense fluttering in her hand, as long as she brewed it, she could drink it, the little girl and Li Yi stayed for a while, let go of their nature, and now they were planning to show off the delicious milk tea to their mother!

Runan followed behind obediently, Li Shimin glanced back at her, and then stopped gently, Runan was startled, and then lowered his head and stopped slowly, Li Shimin walked over slowly, and in Runan's exclamation, he picked up Runan.

"Come, Father and go!"

Li Shimin laughed happily, Runan's shocked eyes with surprise made him uncomfortable, Li Shimin is a natural emperor, but after all, he is still a human being, and there is a soft place in his heart called family affection.

After losing his brother and father, his son, daughter and wife are his last pure land, but it's a pity that Li Shimin in the past only cares about his wife, and even in fact, after having a sister named Xu Hui in the later period, he doesn't care much about the situation of the eldest grandson queen!

However, when Li Yi and Runan met today, Li Yi hugged Changle, the envy in Runan's eyes, but he couldn't escape this observant emperor, and he finally knew at this time that Runan was not her bargaining chip, but his daughter!

The most ruthless is the emperor's family, but who can be truly ruthless!

Before entering the house, Li Shimin heard Changle in the house, showing off his milk tea with Empress Changsun, and what he had seen and heard all day in Li Yi's mansion, Li Shimin walked in with a smile.

The eldest grandson raised his head, and the doting eyes that were originally on Changle's body suddenly changed and turned into surprise, because Runan was riding on Li Shimin's arm.

"Wow......"

Changle exclaimed, Li Shimin at this time, holding Runan with one hand, Runan is now seven or eight years old, and he is still quite big, it is conceivable that Li Shimin's arm strength is still quite good.

"Hahaha, do you want to let your father hug her?"

Li Shimin looked at his daughter's adoring gaze, a feeling called "father", spontaneously, in the past few years, foreign wars, internal wars, and even wars with his brother and father have made Li Shimin extremely busy, and he has also indirectly ignored his son and daughter!

Li Shimin's son and daughter's future problems, Li Shimin has to bear most of the responsibility!

However, whenever the eldest grandson queen takes care of it personally, the son and daughter are still very well-behaved, so from the side, to a certain extent, the mother's influence on the child is the greatest!

"The prince is back......"

Datang does not have anything like "welcoming the prince back to the palace", but a dialogue between ordinary couples, but the title should be a little more particular, and when the people around him retreated, the eldest grandson Wujian was called Li Shimin, and it was estimated that he would be called "Erlang", and Li Shimin also called the eldest grandson Wujian "Guanyin".

"Today is an eye-opener, the magic weapon of the upper realm is really powerful, three acres of land, one person, only less than half a pillar of incense will be all cultivated, Geng Kai's land, a palm deep, it should really be an artifact!"

Li Shimin put down the black bump in his hand, and then put down his two daughters, the two daughters hung on their bodies, and Li Shimin also felt a little heavy!

As soon as the two little girls landed, they ran to make milk tea, and one of them had a cup in his hand, Li Lizhi planned to give it to the eldest grandson, so Runan naturally gave it to Li Shimin.

"Oh, is there such an artifact?"

Although the eldest grandson Wujian was curious about what the black pimple was, as a future queen, hearing such an artifact as a cultivator, it was instantly like the super impact of this artifact on the Tang Dynasty.

"Really, if this is skillful, you can cultivate thousands of acres a day!"

Li Shimin sighed, and then felt a pity, if this thing can come in large quantities, the entire Tang Dynasty can liberate a large number of laborers, Li Shimin is now thinking about the "commercial tax" that Li Yi said, once the business develops, the tax will be ten million times that of the grain tax.

The grain tax may become a dispensable part of the imperial court's income, and even decades later, the grain tax will be abolished!

Li Yi didn't say that in modern times, the grain tax is not only abolished, but also subsidized, you grow grain, the state does not want your grain money, and in turn gives you money.

"Look at the prince's dark color, but it's a pity for that artifact?"

"Hey, what Guanyin said is very true, although the artifact is good, it can be said to be a 'diesel' thing, Li Yi said, this thing is also available in Datang, but it needs to be refined, with the skills of Datang craftsmen today, I'm afraid it is very difficult!"

Actually, it's not difficult at all, find the oil, and then the distillation method can extract the gasoline, but you have to take into account the complex liquid fractionation method, because there are too many things in the oil.

What can be extracted is not only gasoline, but also kerosene, aviation fuel, etc., all depending on the process.

"Secondly, that artifact is expensive, and it is not easy to transport, if it is to be popularized on a large scale, Datang itself cannot build it, and the upper realm cannot transport it in large quantities, so it is just a burden!"

You can only look at the testing machine, but you can't mass produce it, which is the biggest embarrassment of an item.

The process here is very complicated, the most straightforward is the problem of metal, the hardness required by the plowshare, at this stage Datang simply can't play out, let alone make a more difficult engine!

You can't even make a steam engine!

"How's that for good?"

Empress Eldest Sun asked worriedly, this thing is really beneficial to the country and the people, but you can only see it, you can't use it, this is simply too torturous!

"Li Yi said, next time I steal back to the upper realm, I will find someone to ask, if I can improve the straight plow used by my Datang, it can also greatly increase the cultivation speed!"

At the end of the Sui Dynasty and the Wude period, what was the biggest trouble left for Li Shimin?

It's the population!

And a lot of wasteland!

Therefore, Li Shimin has a uniform field system, as long as you have adults in your family, you will have a field share, and then you will organize it yourself and plant it yourself.

But this tidying up the barren land is a huge problem!

Wasteland alone is not something that can be developed rapidly in this country that lacks men.

Therefore, Li Shimin is still very sorry, if Li Yi's cultivator can be supplied in unlimited quantities, how good it would be!

"Forget it, come, Guanyin, don't think about this, come and eat chicken ......"
