When Lu Ming heard the news coming from the ball, he flew over immediately.

"Lu Ming, I found a mine underground. I feel that the metal in the mine here is very high-end, and I feel that I'm drooling when I see it."

Qiuqiu shouted, flying around Lu Ming, extremely excited.

"Very advanced? More advanced than what I encountered before?"

Lu Ming's heart moved and asked quickly.

"Yes, they all have to be high-end, and they are much more advanced, and they look so delicious!"

Qiuqiu shouted excitedly.

"Go and go and have a look!"

Lu Ming couldn't wait.

It is more advanced than the metals discovered before. Can it be used to refine source-level magic weapons?

Lu Ming followed the mine hole dug by the ball and went down.

This time, the mine hole dug by the ball was very deep. Lu Ming felt that he had been flying down for hundreds of thousands of miles and finally arrived at his destination.

"This is"

He found that the depths of the ground were painted black, and from a distance, it looked like a dark night.

"Is this the ore of the Black Sky Source Gold?"

Lu Ming's heartbeat couldn't help but accelerate.

Black Sky Source Gold is an important material that can refine source-level divine weapons, and one of the two main materials that can refine source-level divine weapons.

Another material is called Red Blood Source Gold.

As long as there are enough Black Sky Source Gold and Red Blood Source Gold, plus some other materials with less high levels, you can refine source-level magic weapons.

Of course, if ice and Mars silver is added, the success rate will be higher.

This is the top divine gold that refines source-level divine weapons. Unexpectedly, he really encountered such a large piece.

"Ball, purify some and show me!"

Lu Ming said.

If it is not purified, it is still impossible to accurately judge the ore just by looking at it.

"Okay, but the metal content in this ore is extremely low, so it's not that simple to purify it, and it takes a little time."

After saying that, Qiuqiu opened his mouth wide and bit the black ore with a crunch.

Large pieces of ore were swallowed into the mouth by the ball.

However, it is obvious that the speed of the ball biting ore is not as fast as before. Lu Ming tried it and found that the black ore was extremely hard. Lu Ming's palm was like a knife, and he could only cut a small piece the size of a palm.

Lu Ming now had a full palm, which was even sharper than some main-level magic weapons, and he could only cut off a small piece.

You know, this is just an ore, not a purified metal, it is actually so hard.

No wonder the ball bites much slower.

After more than two hours, the ball swallowed about 100 cubic meters of ore, stopped and began to purify.

It took a full day for the Qiuqiu to spit out a large piece of impurities, and then a piece of metal the size of a longan flew out of Qiuqiu's mouth.

Lu Ming grabbed it and his arms trembled.

Very heavy!

Lu Ming felt as if he had caught a planet as a piece of metal as a longan.

"It's the Black Sky Source Gold, it's true. It's the Black Sky Source Gold, hahaha, I'm really rich!"

Lu Ming was ecstatic.

"Lu Ming, what is this metal called? It feels really delicious, but I don't dare to eat it now. You can save it for me and wait until I refine the impurities before I will give it to me."

Ball fairway.

"This is called Black Sky Source Gold. Don't worry, I will save it for you!"

Lu Ming smiled, laughing so hard that he was very cunning.

Unfortunately, the simple ball can be seen where I can see it, and I was extremely excited immediately.

"This metal level is too high, so I'll purify it very slowly. If my cultivation level is higher, it will be faster. Lu Ming, you have to wait for me more."

Ball fairway.

"It's okay, it's okay to wait a little longer."

Lu Ming said.

"Okay, I'm going to do something big."

Qiuqiu rushed out excitedly and bit the ore with a crunch.

"Qiuqiu, work hard. I will find some broken source-level magic weapons to compensate you later."

Lu Ming muttered in his heart.

Such a precious metal material is naturally not something that can be eaten by Qiuqiu.

The Black Sky Source Gold is extremely hard. If you collect the Red Blood Source Level, plus Ice and Mars Silver, and with some other materials, you can find a weapon refiner to refine the source-level magic weapon armor.

Although the broken source-level magic weapon also contains precious materials, it needs to be purified. It is impossible for ordinary people to do it. It still requires a top weapon refiner to do it. It is too troublesome.

It’s better to eat Qiuqiu.

This time, Qiuqiu gnawed thousands of cubic cubic meters of ore at one time before it began to purify.

Lu Ming sat cross-legged in the same place and realized the prehistoric style.

The prehistoric ring floats above Lu Ming's head, and the spiritual consciousness enters the interior of the prehistoric ring to watch the mountains and rivers and continents inside the prehistoric ring.

The prehistoric ring may be really made of a piece of fragment from the prehistoric continent in the last era, and it is still intact fragments, which are completely different from the fragments in the ruins of the universe.

You can get a glimpse of the scenery of the prehistoric continent in the last era.

Using this as a comparison, Lu Ming always has new understanding of the "precious style".

In the blink of an eye, in the past ten days, Qiuqiu finally purified the ore he had eaten before and obtained a rice bowl-sized black Tianyuan Gold.

"No, not bad. With ten pieces of black sky source gold of this size, it is enough to refine a source-level divine weapon."

Lu Ming smiled happily and took this ball of black sky gold into the prehistoric ring.

Such precious treasures are naturally more at ease in the prehistoric precepts.

Qiuqiu pounced out again and gnawed the Black Sky Source gold ore, while Lu Ming continued to practice.

However, a few hours later, I heard the sound of the ball.

"Lu Ming, Lu Ming, come and see what this is?"

Qiuqiu shouted.

Lu Ming finished his practice and flashed his body, and appeared next to the ball, looking forward.

“That’s it”

Lu Ming was shocked.

On the ore wall covered with teeth marks, there is an egg-sized crystal inlaid.

The crystal stone turned milky white. Lu Ming could feel that the crystal stone contained extremely rich energy, and the crystal stone also had a trace of energy constantly spreading out.

Lu Ming was so familiar with this kind of energy that he refined a lot in the Taishang Immortal City back then.

The prehistoric atmosphere!

Yes, the energy that permeates this crystal is the prehistoric energy.

Then, this crystal is the prehistoric crystal.

Lu Ming's eyes were extremely bright. Unexpectedly, the ore of the black sky gold actually contained the prehistoric crystal.

He speculated that there should be prehistoric crystals in this continent, otherwise so many plants would not be born.

But he had never found it before, and he did not expect that the prehistoric ring was actually sandwiched in the ore of the Black Sky Source Gold.

Lu Ming's palm was like a knife, and he made continuous moves, slashing the ore and the ancient crystals down.

Then the ore on the edge was broken off, and a complete prehistoric crystal appeared in Lu Ming's hand.
Chapter completed!
