The Liang Dynasty would never allow 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, you will be twisted off your head.

"If there is a mine here, Gan Zixu's reaction will make sense." The personal guard came back from the huge impact and said slowly.

Another guard leaned forward and looked carefully and said, "Isn't this for alchemy?"

"I have seen it, you can order tofu. My uncle's tofu shop often uses this product." Another personal guard said.

But it is not very popular to use tofu to cook nowadays.

So the personal guard said inexplicably: "This thing is not worth a lot of money. How can Gan Zixu use it to make a fortune?"

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

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

Xue Qingyin thought that this thing would be famous in later generations!

Because it is a first-class carcinogen.

"This object is not ignited with fire, and has the functions of fireproof, heat insulation, corrosion-resistant, and corrosion-resistant." Xue Qingyin said.

The personal guard couldn't believe it: "How can there be such a thing in the world? I have only heard of the fact that swords and guns are hard to chop, but there are still things that cannot be burned even if the fire is not burned?"

"There is a record in Liezi: When washing the cloth, the cloth must be poured into fire. If cloth is clothed, the color of the fire will be dirty and the color will be clothed. The fire will be released and it will be radiant, and it will be suspected to be snow." King Xuan said slowly without speed.

"So the fire cloth is made of this thing?" The guard was shocked and pinched the white particles and looked back and forth.

"My subordinates have also heard rumors that four or five hundred years ago, the Western Regions paid tribute to the Heavenly Kingdom and offered fire cloth. Because of its rareness, the emperor at that time even said, "It is hard to buy a thousand gold coins."

"But wars have occurred frequently since then, and there have been no traces of fire and cloth for hundreds of years. People in the world say that there is no such magical thing in the world, but it is just fabricated."

"But it turns out there is!"

They were surprised and couldn't let go of their love.

"If you present this thing to Your Majesty, you may also create a good story." One person said excitedly.

Another man hesitated: "If it is used on armor, wouldn't it be possible to guard against enemy rockets?"

"Not bad! This is a powerful weapon for marching and fighting." The others immediately gave up the idea of ​​giving it to the emperor.

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

"What?"

"This... white tasteless, how can it be poisonous?"

Xue Qingyin pinched a little, pulled it apart, revealing the tiny, undetectable fibers in it: "Yes, if you inhale it, it will be 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 and still couldn't believe it.

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

They forgot about the rare and toxicity for a moment, and it does not conflict.

"How could the princess know that it is poisonous?" someone asked in surprise.

Ah, this can stop her from asking.

Of course, it cannot be said that this was released by the World Health Organization.

"I read it in the book." She was covered with her mouth and nose, and she could only say in a muffled voice. Don't ask her which book it is, but I just can't remember it.

She then said, "But you don't have to be disappointed. Most mineral resources are distributed unevenly. Once a place is found in minerals, it is often accompanied by multiple mineral species."

Xue Qingyin thought that Gan Zixu might not recognize asbestos. There must be other rarer minerals that can be called to protect him like this.

"The princess read so many books."

"Yes, yes, it's quite like learning five cars."

The guard in front of him really flattered.

Xue Qingyin was praised and blushed a little.

Only she herself knew that she did not read more books than them, but thanks to the information explosion era in later generations, it was too convenient to acquire knowledge.

"When did you learn to be so slick? Don't praise me. If you really want to carefully distinguish what kind of mines there are underneath... I can't tell it." Xue Qingyin said with a clear mind.

I thought I could not help but kill me!

"This is easy. I will ask Fusha to take a walk in the mountains tomorrow." King Xuan said.

"Who is Fusha?" Xue Qingyin interrupted curiously.

The guards laughed and said, "A half-baked doctor in the army."

King Xuan said indifferently: "He is good at distinguishing plants and trees."

Xue Qingyin's eyes lit up: "I have heard that we can judge whether there is a mine underground based on the types and growth of the grass and trees on the ground. It turns out that it is really feasible?"

She knows nothing.

If someone hadn't brought the minerals underground to the ground and intercepted by the leaves in the forest, she would have really couldn't infer what was below.

"Feable." King Xuan paused and continued: "If it is a gold mine, there will be many Fengyan, iron squid and other things nearby. There will be iron trees growing near the iron mine. There will be honeysuckle and copper grass near the silver mine..."

Xue Qingyin couldn't help but look at her side.

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

"There is no need to stick to this mountain. Xingzhou has many mountains. Ask Fusha to draw a picture book, send more people out and investigate everywhere." King Xuan whispered.

"Yes!" the personal guard responded.

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

"The minerals you mentioned are uneven, but they are very concentrated. There is a mine in Xingzhou, and there may be mines on every hill." King Xuan met her.

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

"I don't believe in the princess' words, who should I believe?" King Xuan asked her back.

Xue Qingyin pursed her lips and thought to herself, why did this person look serious and cold when she spoke love words?

"Yes." The guards suddenly followed and said with a smile: "Your Highness trusts the princess, and naturally, your subordinates trust the princess very much."

Xue Qingyin's cheeks were slightly red, so she didn't turn her face and couldn't help but mutter in her heart.

She remembered that they were all very serious and honest in the past.

Every day, there is a cold and solemn atmosphere in Prince Xuan’s mansion.

Could it be...I really brought the trend wrong?

Xue Qingyin briefly suspected herself.

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

Xue Qingyin even asked in a second voice: "How long have we been gone?"

"It's been two incense sticks." The personal guard replied.

"It's only two incense sticks, it's too short, so let's go around again." Xue Qingyin said.

Do the personal guards think that they are short of their hearts? If they stay here for a long time, wouldn’t Gan Zixu still be suspicious?

But they said just now that they believed in the princess, they would naturally do the same.

Only King Xuan was there, as if he understood what Xue Qingyin was thinking, and the veins on his forehead jumped.

Someone from the other end of Gan Zixu reported to him.

"His Royal Highness Xuan has been here for a long time, and has been incense sticks and has not come back yet..." The servants showed a look of sorrow, "Will they have entered our tunnel?"

"The mountain is so big that there are no villagers leading the way, how could they find the authenticity?" Gan Zixu shook his head and said, "Two incense sticks have been a bit long. However, King Xuan is mostly in the army and is strong. Two incense sticks may not be enough for him..."
