This steep mountain ridge has also become a scattered area and a natural isolation belt outside the border and the Middle Earth.

So, even the Wuyuan people like Hua Niuwei felt desolate and barren when they came here, and couldn't help but ask!

Qingyun smiled but refused to answer, and kept it a secret. After walking for another two days, he arrived at the place.

However, this time when Wu Qingyun came, he felt something was wrong: "It seems that something is wrong. This copper mine seemed to have been discovered..."

Before we could get close to the copper mine, we could see traces of human activities in this mountainous area from afar, and even waste slag could be seen.

"I walked past this neighborhood last time, why didn't I find it? Yes, it's still 10 or 20 miles away from the Yang General Temple.

When I passed by, I didn’t go in this direction!”

This kind of change made Yu Qingyun's heart skip a beat, and he said to Hua Niuwei and others: "Let's hide nearby first and wait until it's dark!"

After dark, a fire light could be seen from the valley from afar. Although most of it was covered, it was not that Qingyun and others were already very close to each other and could not see it at all. Then I heard the sound of ding ding bulging...

But there was a stove in the valley that was smelting and forging metal!

Moreover, it seems that these people who work are tall and naked, they should be Wu Yuan people.

This copper mine was not only discovered, but it has been mined here!

"Copper, this is copper ore!"

Hua Niuwei and the other two recognized each other, and their eyes suddenly lit up. They looked at each other and called out two words: "Weapons!"

In nature, copper has a low melting point and is the easiest metal to smel!

For Wu Yuan people who were backward in civilization, bronze was the only metal they could use to make weapons.

Moreover, although it is desolate on the snow-capped mountains outside the border, there are also rich copper ores, and there are really many bronze weapons produced!

Of course? That's for the truly powerful Wuyuan tribe? Tribes like Huaniu Tai Red Bull Intestine can only get some bronze weapons that have been resold through various channels.

Every bronze weapon? For the Huaniutail Tribe? It is extremely rare!

So that when I saw this scene in front of me, my eyes immediately turned red!

This copper mine is a gift from General Yang and his men to surrender to Wei Qingyun.

Was the frontier army of the Tang Dynasty stationed here in the past? Accidentally discovered it? A secretly discovered mining without telling the court...

However, they did not mine for long, and then they encountered changes.

Then the Tang Dynasty border in the past was completely abandoned and became the uninhabited place today!

"Actually, there are many copper mines on our mountain." Hua Niuwei began to gesture and said with excitement: "But those copper mines were occupied by some large tribes.

Then they were able to cast weapons, and even directly exchanged food with the people at the foot of the mountain to exchange for iron weapons...

Then they will be very good at fighting, and have more food? They can also raise more people.

Now, we also have copper ore in Hua Niu Tai? Our Hua Niu Tai will also become stronger!"

It turns out that this guy also knows this truth.

However, Hua Niuwei was excited to point fingers at Wei Qingyun and just urged Wei Qingyun to grab the copper mine!

Just relying on the four of them to grab the copper mine? It’s just a joke!

Not to mention anything else, just being a miner? There are also witches who are smelting? I'm afraid there are hundreds of them.

I don't know if there is any guard force?

Especially this spiritually unconscious area? It is difficult to cast spells like the modern world...

In such a spiritually unconscious area, these witches with infinite power can play their greatest advantage.

Moreover, even if they can defeat those witch miners, can they really move the mine away or occupy it?

However, after thinking so much, Wei Qingyun was still ready to take action!

It's nothing else, and Qingyun didn't plan to really move these copper mines.

He just needs to condense the essence of Geng and Xin in this copper mine and completely cultivate the Golden Soul Divine Pill!

Only by practicing the Golden Soul Divine Pill can heal his injuries as soon as possible and practice the lung metal energy practice in the true immortal's cultivation!

"If you don't enter the tiger's den, how can you get a tiger's son! You are nearby to protect my body, and I will go and have a look!"

As he said that, regardless of whether Hua Niuwei could understand or not, he sat cross-legged, and his soul quickly approached the valley under the cover of the night.

However, before we even reached the valley, we felt like we were electrocuted...

"No, a formation has been arranged in this valley!"

But when I saw that there was a blue light flashing in the originally normal air. If it weren't for the Qingyun Yuan spirit with dark silver armor, it would be not as simple as being electrocuted, but the soul would have been injured a little!

Qingyun thought to himself that it was not good, and suddenly retreated. At the same time, cloud light emerged, constantly changing, and in a blink of an eye, it was completely integrated with the surrounding environment and disappeared.

Almost the next moment, a dark green flame exploded, and a ghost with half of the bone appeared in the flames.

The flames floated in the eyes of the white bone ghost, as if observing the surroundings.

After a moment, no traces of the blue clouds were found, and the traces were hidden!

The air returned to normal, and everything seemed to have never happened before.

After a while, Qingyun's figure appeared again. He murmured to himself: "It's interesting, there are Taoists and witches. Whose force is the one who discovered the copper mine here?"

Qingyun became more and more curious. Who actually made such a big move?

In such a spiritless area in the diplomatic boundary between the Middle Earth and the Frontier, such a huge formation has been laid out...

This valley is at least five or six miles in radius!

Is it really for this copper mine?

Is a copper mine worth such a huge price?

But Qingyun didn’t know that he was a full man now and didn’t know that the hungry man was hungry!

For him, Qingyun himself, a copper mine is nothing. In the modern world, Qingyun can mobilize countless resources and funds, and can be calculated at any time of the situation in billions or tens of billions.

As long as he opens his mouth, not to mention a copper mine, what is it like a gold mine?

But others don’t think so. What is copper ore? That’s money!

It would be a waste to cast weapons with copper!

This copper is money!

If you cast it directly into copper coins, what can you buy?

The Song Dynasty not only used silver, but also used more copper coins in small transactions!
