When the two of them left the study, Li Xing remembered that the lottery rewarded by the system was useless!

Hurry up and summon the system: "System, system, Honjuku main lottery."

[Ding, feel the host's urgency for the lottery, the lottery items will be distributed directly, please open the warehouse panel to check. 】

"System, are you polite to understand the meaning of the host yourself?"

Li Xing complained and opened the warehouse panel.

I saw a silkworm armor lying alone inside.

Just as he was watching, the attributes of the Heavenly Silkworm Treasure Armor had already appeared in Li Xing's mind.

[Item Name: Silkworm Treasure Armor, woven by the silk of the Otherworld, can withstand knives and guns, water and fire are invulnerable, and it is a treasure to prevent assassination. 】

"Good stuff! You are very polite to the system, if there is such a good thing in the future, you can directly distribute it."

After Li Xing saw the detailed introduction, he was overjoyed, with this Heavenly Silkworm Treasure Armor, he was equivalent to an extra life.

[Ding, feeling the host's wishes, the lottery rules have changed, the lottery interface is temporarily blocked, and all lottery items are randomly distributed in the warehouse. 】

The system's prompt, Li Xing didn't care at all at this time.

Now he has taken out the Silkworm Treasure Armor from the system warehouse.

The silkworm armor is very soft and comfortable in the hand, as if it is underwear.

"This shouldn't be called treasure armor, it should be called treasure clothes, so soft that it can resist knives and guns?"

When Li Xing saw the real thing, he couldn't help but doubt the efficacy of the Heavenly Silkworm Treasure Armor.

He tore hard a few times, but found that he couldn't pull at all.

This silkworm armor is soft, but it is very explained, and there is not even a little deformation.

He walked to the desk with the Silkworm Armor, put the Armor on the table, took out the carving knife for carving the seal from the drawer, and stabbed the armor indiscriminately.

The result was unexpectedly good, the armor was not damaged at all, and there was no trace left by the knife on the desk.

"I'll go, what's the principle?"

Li Xing raised the Heavenly Silkworm Treasure Armor high again and looked at it for a long time, but he didn't find out what the principle was.

This made him sigh: "It is worthy of a super system, and the products are high-end."

When underwear was worn inside, he put on his coat and walked out of the study.

When I returned to the flower hall, I heard Li Gou'er explaining the use of coal to Cui Tingcheng.

And Cui Tingcheng listened very carefully this time, and from time to time he showed a look of thought.

Even when Li Xing arrived, Cui Tingcheng didn't notice it.

It was Li Gou'er who saluted Li Xing, and she came back to her senses.

Hurriedly got up and apologized, "Lord Li, the little woman just heard a lot of things about coal, and I feel that this thing is very magical, and I lost my mind for a while, please forgive me."

"I don't have that many rules here, so it's okay."

Li Xing waved his hand and motioned for Cui Qingcheng to sit down.

Cui Qingcheng sat down, and Li Xingcai continued: "Miss Cui, we are old friends, I won't beat around the bush if there are some things I say, can you tell me the truth, if you let the Cui family promote coal in the whole range of Great Xia, can it be completed before the winter comes?"

"Whole Summer Promotion?"

Cui Tingcheng didn't understand why Li Xing would do this, and he was so urgent, to know that the national promotion was not just as simple as talking, there were many things that needed to be done.

"Yes, the whole Great Xia promotion."

Li Xing spoke again with great certainty.

Cui Tingcheng asked the puzzle in his heart this time: "My lord, why is it so urgent to promote the whole country before the winter comes?"

"I can't bear to see it again, there is a miserable situation of frozen bones on the road in the cold winter, the price of 500 catties of coal is comparable to the price of 20 bundles of firewood, but it can burn longer than 20 bundles of firewood, and it is also warmer."

As soon as Li Xing's words came out, Cui Qingcheng was a little surprised, such a magical thing was so cheap.

You must know that in Daxia, 500 catties of charcoal cost two silver, which is two thousand copper coins.

The price of a bundle of firewood is 40 wen, and 20 bundles is 800 wen

, which is less than a tael of silver.

As long as it is not the kind of poor people who eat and wait for death, ordinary people can afford to consume it, especially listening to Li Gou'er, this coal can not only be used for heating, but also can replace firewood for cooking, which is equivalent to using the money to buy firewood to buy coal.

"Adults are benevolent, little women admire, but just a small Lingwu County can have so much production?"

Cui Tingcheng first flattered Li Xing, and then raised his doubts.

After all, many things can be achieved across the country without just talking about them.

"Naturally, there isn't, so this official wants to cooperate with the Cui family to jointly mine all the coal mines in Great Xia."

It turned out to be to cooperate.

Cui Tingcheng immediately restored the image of a strong woman and began to inquire from a professional point of view.

"My lord, the little woman took the liberty of asking, what is the price of coal mining? How do you distribute the benefits of co-mining?"

Originally, it was cooperation, and Li Xing naturally would not hide it, because what he wanted was not profit, but fame and prestige.

He smiled: "Now in the territory of Great Xia, we can only mine open-pit coal mines, and the mining cost will not exceed 100 Wen per 1,000 catties, plus transportation, the total cost will not exceed 500 Wen."

After Li Xing said this, Cui Qingcheng frowned.

There is only a profit of about 300 wen for 1,000 catties, plus the share with Li Xing, I am afraid that the family will not agree to this business.

So she organized the language and said, "My lord, this kind of thing for the benefit of the people, the little woman is very willing to cooperate, but the profit is too small, even if it is shared equally with the adult, the family side may not agree."

"No, the profits don't need to be divided equally, and the official doesn't take a penny, just let the people know that the coal found by the official will be promoted to the whole country."

Hearing this, Cui Tingcheng understood.

It turns out that this Master Li is not good at money and good reputation.

Xing Guogong's son is really different from the others.

"If that's the case, Allure will do his best to make this happen when he returns to the family this time."

Cui Tingcheng is a cautious person, although he thinks that such a good thing in his heart, the family should agree.

But in order to avoid unexpected situations, he still did not agree immediately.

"Then trouble Miss Cui, while you are free now, Miss Cui will go to the coal mine with me to see how about it?"

Li Xing actually had no choice but to do so.

If he wants to change Great Xia and improve the living standards of the people, he needs to exchange for more items.

But as long as the technology beyond this era is surpassed, it is sky-high.

So he had no choice but to make this decision.

"That's what the little girl means!" Cui Chengcheng is also looking forward to what this coal that was praised by Li Gou'er looks like!

Of course, there is one reason why Cui Tingcheng agreed so happily, that is, she wants to divert her attention from this and stop thinking about her brother's arrest.
