I became emperor in the Tang Dynasty by relying on the palace fighting system

In order to alleviate the problem of population growth, it is impossible to change only this one article in the household marriage law.

Li Zhi and Wu Meiniang simply changed all the laws at once. Even if unmarried men and women did not get married after the age of 18, they did not have to pay a fine, and they did not have to arrange a marriage.

Wu Meiniang even issued an order requiring all provincial and municipal government offices to inform the world of the dangers of early marriage and early childbearing.

Yu Dou Xuan Zun said it himself that if a man marries early, his kidney water will be damaged, which will shorten his lifespan; if a woman gives birth early, the fetus will have difficulty surviving, the mother’s body will be damaged, and there is a possibility that both mother and child will die. So who would dare to marry and have children early?

When the people heard this, they were all terrified. Those who were about to get married postponed their engagements, those who were dating each other delayed the six rituals, and those who had already married would have sex later.

For a while, the matchmaker's business became quiet and there was almost no one at the door.

The night in Yunzhou is quiet. The jade plate in the sky lies quietly in the soft clouds, illuminating all things in the world.

Li Zhao put on the Void Crane Cloak and came to the wilderness.

"Qingluan, open the item [Smart World Map], I want to compare and find something."

Qingluan opened the [Smart World Map] as instructed, and a light blue light gradually spread out in front of Li Zhao's eyes. Li Zhao looked left and right, and even looked up at the starry sky, comparing the longitude and latitude on the map.

Qingluan flew beside Li Zhao and turned his head around: "Zhao Zhao, what are you looking for? This is just a desolate wilderness."

Li Zhao squatted down and grabbed a handful of soil: "Silly man, Yunzhou is the future Datong of Shanxi. What do you think I am looking for?"

Qing Luan was slightly startled, then realized: "Oh! It's a coal mine!"

Most of the good coal is hidden underground, and it is too tiring to dig it with a shovel by hand. So Li Zhao specially found a super magic weapon from the hidden goods in the system space!

A long, thin Luoyang shovel!

Yes, it is the great invention of tomb robbers, the Luoyang shovel.

By digging a shovel and then pulling it up, you can clearly see whether there is coal under the soil.

Qingluan's bird face was full of admiration: "Wow, Zhaozhao, you are still a thief friend! You even have a Luoyang shovel!"

Li Zhao forced a smile: "No, I bought this at a flea market. I was a rookie at that time and didn't know much..."

I was tricked into buying this thing.

Qing Luan laughed awkwardly: "Oh, oh, that's how it is."

The last shovel didn't bring up any coal, so Li Zhao changed the spot and continued shoveling: "Let me look again. I remember reading in my high school geography textbook that there is a large open-pit coal mine in Antaibao, Datong. It should be nearby."

Qingluan’s surprised face: High school geography book, such an ancient thing, such ancient knowledge.

The host actually still remembers this.

Open-pit coal mining is easy, has high collection efficiency and low cost. In ancient times when there was no large-scale mining machinery and technology, it was undoubtedly the best choice for mining coal.

[Smart World Map] only provides the map of the current era in the host's world. There are some differences between the maps of the Tang Dynasty and the modern times. Li Zhao compared them for a long time before finding such a place.

Coal is an important resource and the lifeblood of industry. In ancient times, coal played a big role in heating, cooking, building roads, and making simple fertilizers...

So, Li Zhao must get it.

Her main purpose of coming to Yunzhou was to conduct on-site survey of the location of the mineral deposits.

In a moment, the Luoyang shovel knocked out a large piece of soil. Li Zhao pinched the soil and chuckled, "This is it. I'll ask Li Chao to buy this place later."

"After buying it, we can build a village, and then we can lie dormant for a while and concentrate on building the grassroots!"

The next day, Li Zhao invited Li Zhi, Wu Meiniang, Princess Wencheng and others to come to this place together.

All you can see here is a stretch of yellow earth, with hardly any grass growing. It's obviously a barren land.

Li Zhi muttered in his heart: What is Yudou Xuanzun doing now?

He soon found out.

Li Zhao looked puzzled: "Ali, why did you bring me here?"

Li Chao smiled and said, "Jian Zhuangzi. There is something here called coal, which can be burned to keep warm."

Shitan is the ancient name for coal.

"I saw that the people in this world lacked food and clothing in winter, especially charcoal fire. Many died of starvation and freezing. I felt very sad, so I wanted to do something for them."

Pei Xingjian frowned and said, "You don't know, Star Lord, coal can indeed be burned to keep warm, but it is poisonous. In winter, many people have died of coal poisoning."

This is also true. People are not unaware that coal can be burned for heating. As early as the Qin and Han Dynasties, people burned coal in the winter.

However, winter in the north is not so easy. In order to avoid freezing to death, people will try their best to block all the gaps in doors and windows.

If they burned coal at this time, the carbon monoxide produced by incomplete combustion was enough to suffocate their entire family, and this led to the saying of coal poisoning.

If people don't burn coal, they will freeze to death. If they burn coal, they will suffocate to death. Either way, they will die.

Li Zhao certainly understood this. She sighed to herself that life was so miserable for the people in ancient times.

She came here to change all this!

The program that Li Zhao had set for Li Chao continued to work. Li Chao smiled and said, "I understand. This is simple. Just use alchemy to remove the toxicity of coal."

Li Zhi, Wu Meiniang and the others' eyes lit up instantly, but Li Zhao pretended to be nonchalant: "Why are you bothering with all this?"

Li Chao explained helplessly: "Sister, have you forgotten? Taiwei Mother Goddess asked you to accumulate more merits when you came down to earth to experience tribulations this time, and you haven't done anything yet!"

Li Zhao tilted his head, suddenly realizing: "Oh! If you hadn't told me, I would have almost forgotten it."

Li Zhi and Wu Meiniang: You can even forget this. You are indeed a cold-blooded god who treats mortals as worthless.

Li Zhao waved his hand casually: "I'll leave this matter to you, do whatever you want."

Li Chao looked at Li Zhi, who was very pleased and said, "I will issue an order to designate this area as Xuanzun's manor."

Li Chao nodded to him and said, "Thank you, Your Majesty. I also bought a piece of land in Yunzhou, let's enclose it together."

Li Zhi agreed to everything. After all, this piece of land was wasteland and that piece of land was bought with money. The Star God of the Li Dynasty would return to heaven sooner or later, and it was impossible for him to move an ordinary mortal manor to heaven.

Once the two manors are completed, they will benefit the people of the Tang Dynasty and the Tang Dynasty will not suffer any loss.

Li Zhao: Anyway, your Tang Dynasty will become mine sooner or later. I won't suffer any loss after I finish all these today!

Wow gah gah gah gah gah!

The two sides reached a friendly agreement. As for how to assign people to manage it, Li Zhao directly bought some slaves from the local area and opened the [Fourth Disaster Module] by the way, intending to summon someone to help.

In Yunzhou, in a deep mountain forest, there grew a tall sacred Fusang tree with green leaves and white jade branches. Under the tree lived the mythical Black Tortoise beast, and two giant pythons with black scales and golden eyes coiled around the trunk, dozing with their eyes closed.

There are flower buds hanging on the branches of the sacred tree, and countless human figures are sleeping inside.

Qingluan poked the flower bud and said, "The program modified by the main system is good. The fourth disaster was born from the Fusang sacred tree guarded by the Xuanwu sacred beast. This appearance is quite fairy-like."

"【Fourth Calamity】 can summon people from the host's world to help. Zhao Zhao, who do you want to summon?"

Li Zhao said leisurely: "I don't know much about doing business and making money, but there are two people who are the best in it."

Qingluan: "Who?"

Li Zhao smiled and said, "Female heroes of the Republic of China, Lü Bicheng and He Xiangning."

Lu Bicheng, He Xiangning, a heroine of the Republic of China, an elite female businessman, and a pioneer of feminism.

Qing Luan stared in astonishment: "Lü Bicheng and He Xiangning, the pioneers of feminism in the last century?!"

Li Zhao chuckled and said, "Yeah, didn't you say that I can summon people from my world to help me?"

"Lü Bicheng and He Xiangning are also from our world!"

Li Zhao started the program, and the system module ran rapidly, capturing the dead souls from another world!

Deep in the mountains and old forests, the Black Tortoise on the Fusang sacred tree slowly opened its eyes and uttered a low groan that ordinary people could not hear, shaking the heavens and the earth!

Between heaven and earth, the situation suddenly changes.

Li Zhao laughed enthusiastically in the strong wind!

"Welcome to the game world of [Stars Save the World]!"

"The Star Lord of the City Tower, Lu Bicheng."

"Che Si Xingjun, He Xiangning."

Two pioneers from another time and space opened their eyes in the Tang Dynasty of this world.

"The world's great unity begins with the great unity!"

Li Zhao's smile is as beautiful as spring.
