Chapter 504

Zhan Beihan said: "If you want to find out whether there is iron ore in a place, the easiest way is to dig out the rock layer and see the quality and markings of the rock. Experienced prospectors can tell it at a glance."

"Is prospecting so simple?" Xiao Lingyue couldn't help but be surprised.

But then she thought that the ancient prospecting technology was rough and there was no professional machinery to help, and it all depends on experience and eyesight.

Many experiences have been passed down from generation to generation, with very low accuracy. The chance of successfully probing a vein is probably the same as a blind cat hitting a dead mouse.

What's more, discovering iron-containing mines from the field is different from actually mining and smelting iron tools.

Some iron ores have very low iron content.

It may be good if you work hard to dig out hundreds or thousands of kilograms of ore, and finally you can refine a few kilograms of iron.

Because of this, iron tools in ancient times were particularly expensive and were a strategic resource strictly controlled by the imperial court.

Xiao Lingyue looked at Zhan Beihan curiously: "How do you know about prospecting? I have asked someone for a question?"

Zhan Beihan looked at her coldly: "The appearance of iron marks on the rock means that the iron ore is not far away. Don't waste time here!"

After speaking, he took his long legs and walked forward with big strides.

Xiao Lingyue raised her eyebrows and quickly chased after her: "You haven't answered me yet! Do you know the knowledge about prospecting? Did you ask someone for questions?"

Prospecting is a hard physical job and belongs to a poor and poor industry.

People in charge of mine prospecting often have to travel through mountains and rivers and enter the mountains and ridges. The hardships and dangers faced by laymen are unimaginable.

Zhan Beihan was born into a noble family and had never suffered any hardships except on the battlefield since he was a child.

If he hadn't asked someone specifically, how could he know about prospecting?

Zhan Beihan ignored her.

Xiao Lingyue tskated and said, "This is not shameful, tell me what's wrong?"

Zhan Beihan suddenly stopped and looked at her with a dark face: "Why do you talk so much?"

"Who told you to ignore me?" Xiao Lingyue said with confidence.

"I haven't asked, are you satisfied?" Zhan Beihan said with a calm face.

"Then how do you know? Are you interested in prospecting?" Xiao Lingyue looked at him in confusion.

Zhan Beihan said angrily: "When I first entered the court, my father ordered me to go to the six departments to practice. I found out by chance. What's the problem?"

Xiao Lingyue suddenly realized: "No wonder"

She didn't know before that Zhan Beihan had joined six divisions in addition to the military camp.

No wonder he didn't care about the affairs in the court, but he knew the situation in the court.

Zhan Bei looked at her coldly: "Have you asked enough?"

Xiao Lingyue smiled and said, "Isn't this too boring to go to the secret passage? Just find a topic to talk about to relieve boredom."

"Relieve boredom?" Zhan Beihan sneered, "Who gives you the courage to relieve boredom with me?"

Xiao Lingyue looked at him innocently.

The jumping fire reflected on her face. In this gloomy underground secret passage, her porcelain white cheeks crossed a layer of warm light, her eyes were black and bright, and it seemed that there was a line of words written - what can you do to me?

Zhan Beihan almost died of anger.

This woman is becoming more and more bold in front of him now!

I used to know how to pretend to be well-behaved and weak.

Now I am completely disguised, and my face is thicker than the city wall.

Zhan Beihan glared at her fiercely: "If I waste my time, I will ask you!"

After speaking, he turned around and walked forward.

Xiao Lingyue couldn't help laughing for a moment, laughed in her heart, and followed him with an oil lamp.
