The Liang Dynasty never allowed private mining.

In fact, let alone the Liang Dynasty, it is not allowed in any dynasty.

Important things such as salt and iron, if you dare to mine them privately, the heads of the nine tribes will be screwed off for you.

"If there is a mine here, then Qian Zixu's reaction would make sense." The guard said slowly after recovering from the huge impact.

Another bodyguard came over, took a closer look and said, "Isn't this for making alchemy?"

"I've seen that you can order tofu. My uncle's tofu shop often uses this." Another guard said.

It’s just that cooking with tofu is not very popular nowadays.

So the guard said in confusion: "This thing is not worth a fortune. How can Qian Zixu use it to make a fortune?"

"The thing you are talking about is gypsum, but this thing is more like asbestos." Xue Qingyin corrected.

"Asbestos?" They looked at each other, thinking they had never heard of this thing.

Xue Qingyin thought that this thing would have a great reputation in later generations!

Because it is a first-level carcinogen.

"This material is non-flammable and has the functions of fire prevention, heat insulation, corrosion resistance and corrosion resistance." Xue Qingyin said.

The guards couldn't believe it: "How can such a thing exist in the world? I have only heard of things that are difficult to cut with swords and guns, but there is something that cannot be burned by fire?"

"There is a record in Liezi: if the cloth is covered with fire, the cloth will be thrown into the fire. If the cloth is stained by fire, the cloth will be colored. When it is shaken by fire, Haoran doubts it is snow." King Xuan said without hesitation or slowness.

"So the Huohuan cloth is made of this material?" The guard was shocked, holding the white particles and looking back and forth.

"My subordinates have also heard rumors that four or five hundred years ago, the Western Region Kingdom offered fire-huan cloth as tribute to the Celestial Empire. Because it was rare and rare, the emperor at that time even said, 'It is difficult to buy an inch of cloth with ten thousand gold.'"

.

"But wars broke out frequently after that, and there was no trace of Huo Huanbu for hundreds of years. The world said that there was no such magical thing in the world, and it was just a fabrication."

"But it turns out there really is!"

They were amazed and couldn't put it down.

"If I present this thing to His Majesty, I'm afraid it will create a good story." One person said excitedly.

Another person hesitated and said: "If it is used on armor, wouldn't it be able to protect against enemy rockets?"

"Yes! This is a useful weapon for marching and fighting." The others quietly gave up the idea of ​​presenting it to the emperor.

Xue Qingyin poured cold water on them at this time: "This material is poisonous to mine."

"What?"

"This... is white and odorless, how can it be poisonous?"

Xue Qingyin picked up a little bit and peeled it open, revealing the tiny, imperceptible fibers inside: "Well, if you inhale it, it's poisonous."

When King Xuan heard this, he frowned and raised his hand to cover Xue Qingyin's mouth and nose.

The others looked at each other, still unable to believe it.

This thing is extremely rare in historical records, so how could it be poisonous?

They momentarily forget that rarity and poison are not in conflict.

"How did the princess know it was poisonous?" someone asked in surprise.

Ah, this is a question for her.

Naturally, we cannot say that this was issued by the World Health Organization.

"I read it in a book." She had her mouth and nose covered, so she could only say in a low voice. Anyway, don't ask her which book it was, I just couldn't remember clearly.

She then added: "But you don't have to be disappointed. Mineral resources are unevenly distributed in most areas. Once a mineral is discovered in one place, it is often accompanied by multiple mineral species."

Xue Qingyin thought that Qian Zixu might not recognize asbestos. For him to be able to protect his life like this, there must be other more rare minerals.

"The princess reads so many books."

"Yes, yes, he is quite knowledgeable and knowledgeable."

The guards in front of me really flattered him.

Xue Qingyin blushed a little after being praised.

Only she knows that she has not read more books than them, but thanks to the era of information explosion in later generations, it is too convenient to obtain knowledge.

"When did you learn to speak glibly? Don't try to flatter me. If you really want to carefully distinguish what's underneath... I can't tell." Xue Qingyin said with a clear mind.

Don’t even think about flattering and killing me!

"It's easy. I'll ask Fusha to go for a walk in the mountains tomorrow," King Xuan said.

"Who is Fusha?" Xue Qingyin interrupted curiously.

The guards laughed and said: "A half-assed doctor in the army."

King Xuan said quietly: "He is good at distinguishing between vegetation and trees."

Xue Qingyin's eyes lit up: "I once heard that you can judge whether there is a mine underground based on the types and growth of vegetation on the ground. Is it really possible?"

She knows nothing.

If someone hadn't brought the minerals from the ground to the surface and trapped them in the leaves of the forest, she really wouldn't have been able to deduce what was underneath.

"It's feasible." King Xuan paused and continued: "If it's a gold mine, there will be many orchids, iron mangosteens and other things nearby. There will be iron trees growing near the iron mines. There will be many honeysuckles and coppergrass near the silver mines..."

Xue Qingyin couldn't help but look sideways.

From this point of view, it is King Xuan who really reads more...

"There is no need to stick to this mountain. There are many mountains in Xingzhou. Ask Fu Sha to draw a book of illustrations and send more people out to investigate everywhere." King Xuan ordered in a low voice.

"Yes!" the guard responded.

Xue Qingyin smiled and said: "Your Highness is really wise."

"The mineral areas you mentioned are not uniform, but they are very concentrated. There is a mine in Xingzhou, and maybe there are mines on every mountain." King Xuan met her eyes.

Xue Qingyin couldn't help but whispered: "Your Highness really believes in me..."

"I don't believe the princess's words, whose words should I believe?" King Xuan asked her.

Xue Qingyin pursed her lips, wondering why this person always looked so serious and cold when talking about love?

"Yes." The guards suddenly laughed and said, "Your Highness trusts the princess, and naturally his subordinates also trust the princess very much."

Xue Qingyin's cheeks were slightly red, she turned away, and couldn't help but murmur secretly in her heart.

She remembered that they were all quite upright and honest in the past.

Every day, there was a cold and solemn atmosphere in Prince Xuan's palace.

Could it be...that I have brought the trend to a wrong level?

Xue Qingyin briefly doubted herself.

At this time, a guard asked in a low voice: "Your Highness, are we still going inside? Or should we go back first and wait for Fusha to come and explore tomorrow?"

Xue Qingyin interrupted first and asked, "How long have we been walking?"

"It takes two sticks of incense," the guard replied.

"It's only two sticks of incense. It's too short. Let's walk around a little longer." Xue Qingyin said.

Are the guards short-minded? If they stay here for a long time, won’t Qian Zixu still become suspicious?

But they had just said that they believed in the princess, so naturally they had to do the same.

Only King Xuan was beside him, and he seemed to understand what Xue Qingyin was thinking, and the veins on his forehead jumped.

Someone on the other side of Qian Zixu also reported to him.

"His Royal Highness Prince Xuan has been away for a long time. He has burned two sticks of incense and has not come back yet..." The servant looked worried, "Could they have entered our tunnel?"

"The mountain is huge and there are no villagers to guide the way. How could they find the tunnel?" Qian Zixu shook his head and said: "Two sticks of incense are too long. But King Xuan was mostly in the army and was in strong health, so two sticks of incense are not enough for him.

I'm afraid it's not enough..."
