"What kind of stones are they?" Mu Dong looked at those stones, and then it was time to test his acting skills.

"This is a refined copper stone!" These stones that Boss Niu inadvertently dug up in the earth spirit world, after preliminary testing, from the outside of the stone, what was revealed was refined copper, so it was considered to be a refined copper stone.

Refined copper is a special ore, which will only appear in places with abundant spiritual energy, and there is usually a spiritual vein in the buried place, which will allow ordinary brass to absorb spiritual energy and advance to refined copper.

The value of refined copper is not low, but it is not particularly high, and it is priced according to its size.

Boss Niu's eyes purred, and he quoted a price, "These ores have refined copper in them, and according to experts' estimates, the refined copper contained in each piece is the size of an adult's fist, so the value is 30,000 pieces!"

The value of fist-sized refined copper is about 30,000 yuan on the market, and there will be a fluctuation in quality.

However, Boss Niu's so-called expert estimates are actually blind, according to his eyesight, the trend of refined copper in this stone is not very good, so it is the size of a baby's fist, which is about three times worse than the adult fist just said.

However, this is the doorway to sell stones, and there is also a kind of gambling in it, just like the gambling jade in the past, how much ore there is in it is all up to luck, and there is also a part of the eyesight in it.

When Mu Dong heard the offer of 30,000 yuan, he actually felt that it was very worthwhile, the real price of a dragon's blood stone was about 150,000, and one piece was enough to buy 5 of them.

However, he still has to bargain, and he can save a little.

After thinking of this, he shook his head pretending to be dissatisfied, put the stone back in its place, and continued to look at other jade slips.

Sure enough, Boss Niu saw that Mu Dong seemed to be interested in ore, but he seemed to give up because of the price, so he asked, "What?

Mu Dong took over the topic, "It is indeed a little expensive, although there is refined copper on this stone, but the trend of these ores is not very good, how much refined copper is inside, if this piece is sold for 30,000, it is really expensive..."

Boss Niu grinned, "The young man didn't expect you to know a lot, so let's do it, if you want these pieces of refined copper, you can give you 20,000 pieces!

Mu Dong pretended to hesitate, but he didn't hesitate for long, "Okay, then I'll have all five pieces!"

Since I bought them all, it was easy to see the problem if I picked three of them, and it didn't cost much anyway.

"Okay, wait a minute..."Boss Niu very quickly loaded up five pieces of refined copper ore, this is a big business, one hundred thousand yuan in the account, a lot of money.

After Mu Dong paid, he took the ore, each of which was about the size of a football, but the amount was not much, and it would not be too important to hold in his hand.

"Brother Dong, it's also a good thing for you to buy this?" Meng Long didn't know much about ore, and he wasn't very interested in it, but Mu Dong's vision was unique, maybe there was something good in it.

"It's nothing special, I just want to make some refined copper and use it in refining weapons in the future. Mu Dong didn't say anything else, these pieces of refined copper can't be seen as dragon's blood stone from the outside, they are all contained inside, otherwise they wouldn't be sold according to the price of refined copper.

"Oh!" Meng Long didn't continue.

A few people continued to wander forward, but they didn't come across anything good, and they didn't buy any more jade slips, and finally left the bazaar.

"Brother Dong, there are a total of nine holy places in this Northern Cang Domain, and we are only the most marginal position at present, but even if it is the edge, the alien beasts are also very powerful, there are very many spiritual blood alien beasts here, and mortal-level alien beasts are rare..."

The spiritual energy here is abundant, and many powerful alien beasts have been bred, and no human has entered this spiritual realm for ten thousand years, and some of the alien beasts are already unimaginably powerful.

"Where are we going now?" Meng Long decided to follow Mu Dong's advice, after all, this Mu Dong was the strongest in the team.

"There is an area near here called Lei Yanchuan, I heard that Lei Yanchuan is the best place to refine the body, I think we should go there and have a look!" Mu Dong now wants to refine his body to the limit level, and now he has only cultivated to the third level, and there are still many ways to cultivate.

Refining the body does not necessarily need to use spiritual values, and there are also some Kwai Treasures between heaven and earth, which can make the refining body quickly, but it will be very difficult.

Meng Long turned around and said, "Cheng, I have no opinion anyway! Xu Jiang, what about you?"

"I agree too!" Xu Jiang now only has the strength of refining the eighth stage, and he still needs the assistance of two other teammates to move forward smoothly, so he will not have any opinions.

After the group determined the goal, they prepared to go to Lei Yanchuan.

There is a teleportation array here, and everyone who pays 500 federal coins can enter the range of Lei Yanchuan.

...

It was a mountain, winding and undulating, like a lying dragon.

Unlike the usual mountains, the mountains here are all black and do not have any greenery on them, but are bare.

The sky was covered with dark clouds, and even the midday sun could not reveal the slightest light, and the whole mountain seemed as if it was nightfall.

A fluorescent flash flashed through the teleportation array, and three figures appeared from inside.

'Click!'

Suddenly, a purple lightning bolt streaked across the night sky in the distance, slashing at the top of a mountain, staining the sky with fire.

"This is Lei Yan! Where Lei Yan passes, cultivators can go in and refine their bodies!" Mu Dong sighed at the magical power of nature, if he could induce these forces to refine a few bodies, he would have more and more power.

Xu Jiang saw the appearance of this thunder and lightning triggering the firelight, and his heart palpitated, "Brother Dong, will it be too dangerous to refine the flesh body with this method?"

"The path of cultivation is to sail against the current, and if you don't advance, you will retreat! If such difficulties are difficult to resist, how can you achieve the Great Dao?" Mu Dong has an extremely firm heart in his heart, no matter how difficult his cultivation is, he will not have any emotions to retreat.

"Brother Dong is right!" Meng Long didn't have any fear, but was a little eager to try, "Let's go forward, find a thunder fire that can be cultivated, and temper the body!"

Several people began to walk forward, and after a while, a lightning bolt struck a small mountain peak, and the originally black rock began to burn into flames.

After Mu Dong observed carefully, he said: "This mountain peak is not high, the flames are average, not too fierce, suitable for cultivation!"

The thing that burned was mainly black rock on the ground, which was not an ordinary rock, but a strange ore called phosphorus igneous rock.
