This demon beast had rough skin and thick flesh, and Chu Nan had to grind it for more than three hours, and it was dark before he hunted it down.

The whole person was tired and paralyzed.

But Chu Nan didn't rest, he first found a knife, cut off the relatively intact leather of this demon beast, and simply made it into a vest.

He then threw it into the Spatial Ring.

Because there was no water to clean up, this vest was not easy for him to wear now, and then, he removed the demon beast core and some useful parts.

These things can be sold for a lot of money when you go back......

In fact, Chu Nan was in this relic mine, casually looking for some crystal nuclei, and after he went back, he would sell them for more money than this, but he was used to being poor before, and he was still reluctant to throw away this kind of leather muscle worth thousands of spirit coins.

Then, Chu Nan groped around the corpses again, although these people didn't have expensive things like space rings, they still had a lot of rune paper on their bodies.

What kind of wood yuan talisman, flame talisman, Chu Nan found a lot of them, not to mention twenty or thirty of them, and threw them all into the space ring.

"Ghost Ghost ~"

I saw Chu Nan grinning when he was smiling.

He actually found a bronze-level secret treasure on one person's body!

It was a short sword of fine iron, about one meter and a half long, one finger wide, and its whole body was silvery-white, and its sharpness was almost blown.

Whew!

Chu Nan played a set of swordsmanship indiscriminately, and generally figured out that this sword provided physical attack attributes, but it was only a grade of the fourth order of bronze, and the power it exerted was a little higher than that of the third order of bronze.

Although for the current Chu Nan, the power provided by this sword is too weak, but after all, it is a secret treasure, much stronger than ordinary weapons, and with attributes, it is still very handy.

......

Then, Chu Nan thought about it and went into the cave.

Now that it's getting dark, you need to find a place to spend the night, and this cave is a very good choice.

When you go in, it smells a little fishy, but after the demon beast is killed, it is much safer to rest in this cave than outside.

In this big battle, Chu Nan was already very tired, and he felt that as long as he fell down now, he would be able to sleep on the top of the sky. If you're outside, you don't know if you're killed.

"Ahem, ahem!"

The stench in the passage was so bad that Chu Nan only coughed when he was choked.

He picked up the Dan Huo with the sword in his hand, and with the help of the firelight, continued to go deeper into the cave.

After walking for a short time, Chu Nan's front suddenly opened up.

I saw that the space here is the size of a movie theater, surrounded by various stalactite ores, and there are sparse luminous stones around the mine to provide lighting.

What makes Chu Nan the most comfortable is that there is no smell here, and although the air is not sober, it is still much better.

Inside this mine, there is also a dark river, which is pitch black and bottomless, and it is not known where it leads.

"Are there any peerless treasures?"

Chu Nan's sleepiness disappeared a lot, and in such a magical cave, the plots from those fantasy novels on the earth suddenly poured into his mind, and he saw those eyes, turning straight away.

......

However, after searching for a long time, I didn't find any particularly anti-heaven treasures, but found five or six high-grade crystal nuclei.

Subsequently, Chu Nan took out the demon beast leather in the space ring, washed it many times in the dark river, and even burned it with Dan Fire for a while, and after the fishy smell on it was gone, he put it on the inside of his coat.

The leather of this demon beast is very slippery and very soft, wearing it on the body is like wearing soft armor, Chu Nan estimated that if any girl came over with a palm, she would definitely be slipped and thrown into her arms......

After thinking for a while, Chu Nan found a comfortable place and took out a cyan rune paper.

The Avatar Rune, which was just found from those corpses, was used specifically to refresh one's mind.

Although Chu Nan is already sleepy now, he still wants to take advantage of the time to use the crystal nucleus obtained today to strengthen his skills before resting.

The stronger the strength, the more secure and the better chance of survival in this bloody trial.

Chu Nan couldn't take a break, and after forcibly refreshing himself, he began to absorb the crystal nucleus.

......

Three thousand meters outside the cave.

A man in black standing on top of a hill in a black robe looked very mysterious. He held a crystal ball in his hand and a golden piece of paper floating above his head.

And the momentum on his body is even more subtle and powerful, flowing with the breath of the silver realm......

I saw that the man in black had his eyes closed, and after a while, he suddenly opened his eyes, flashing with strange light, and then walked towards a stone not far away, and when he reached the front and back, he saw that he blasted the ore away with one palm, and then a fist-sized crystal nucleus rolled out.

"Bronze seventh-level crystal nucleus!"

The man in black had a hoarse voice and couldn't hear any emotion.

Putting away the crystal nucleus, he did the same thing again.

I saw that every once in a while, he would walk towards a stone, and after knocking it open, a high-grade crystal nucleus would definitely appear.

If this scene were seen by others, they would simply fall out of their eyes in shock.

When did it become so easy to open a crystal nucleus?

It's a hit!

If Chu Nan was here, he would definitely vomit blood.

He thought that he was already the biggest winner in life when he came to the ruins mine this time, but compared to this big guy, he was not at the same level at all!

He touched the stones one by one, and his hands were calloused.

And what about people, if you close your eyes and sense for a while, you can find out the ore containing crystal nuclei, which is too strong, right?

......

Seeing the man in black for a while, he found more than a dozen bronze crystal nuclei above the fifth order.

And it can be seen that this man in black only opens high-grade crystal nuclei, and he may not be able to look down on low-level ones.

But it's right to think about it, when you get to the mine, there are ores everywhere, and time is limited, if you spend a lot of effort on low-level crystal nuclei, it will be a sin!

"The probability of ore on this mountain range containing crystal nuclei is much higher than that on other mines, could it be that there is a vein in it......"

Suddenly, the man in black stopped and said in disbelief.

Then, after closing his eyes for a moment, he continued to mine ore in the mountains.

However, the scope of this activity is obviously very large, and it seems that mining ore is secondary, mainly looking for the so-called "ore vein" in his mouth.

......

After wandering like this for an unknown amount of time, the man in black unconsciously approached the mine where Chu Nan was resting.

At this moment, the golden paper suspended above his head suddenly trembled, as if sensing something unusual, and it seemed quite human, as if he was jumping excitedly......

And at this moment, the man in black was even more excited than this golden paper, and the excited expression on his face was simply vivid and made his whole person look very hideous.

"Chu Nan!"

The man in black spat out these two words between his teeth!

He knew that he could make such an abnormal movement on the golden paper, and among the people who went to the blood-colored trial this time, only the treasure on Chu Nan's body would trigger this kind of resonance......
