This is a very large mining area, even if hundreds of people dig in it, it feels spacious, and a group of monks have found an area to start mining, and the casual cultivator has also found an area alone and sacrificed his magic weapon.

However, just as he struck the copper concentrate with his magic weapon, a bloody arrow suddenly shot out from the rock wall and hit him in the left eye.

"Ahh The sanxiu screamed, and then immediately covered his left eye and shouted in pain, which immediately alarmed the others.

"What's going on?" Qin Di asked loudly.

"Click!" The rock wall shattered, blood flowed out, and then turned into a blood mist, and Sanxiu covered his eyes in pain and shouted, his eyes were completely burned into holes by the demonic blood, and he looked extremely shocked.

"Everyone should be careful, this mining area hides the blood of the demons, which has contracted due to the squeezing of the years and months, and once it is released, it will shoot out like an arrow." Xiao Niansheng reminded.

"It's been hundreds of thousands of years, and this blood can still be preserved, it's really terrifying!" Some monks felt chills in their hearts, this place was too terrifying, and he would not have ventured here if it weren't for the copper concentrate.

Qin Di handed Na Sanxiu a bottle of Returning Spring Pill, and he said, "Please be careful, this place is a little weird. ”

San Xiu swallowed an elixir, and the blood in his eye socket was immediately stopped, but the huge hole could not be repaired.

"This is the blood of the Demon King, so it has not solidified and dried up after millions of years, and it still has a strong lethality, everyone should be careful." Xiao Niansheng continued to remind, he had already noticed that a demon king was buried in this place in ancient times, and his bones and blood were buried here, and millions of years have passed, and the blood has not dried up.

Everyone immediately carefully dug up the copper concentrate, but the bold monk didn't care about any demon blood at all, he kept hitting the rock wall with a golden mace, and then collecting copper essence, every time he was very reckless, but no demon blood rushed out.

Maybe the demon's blood has been drained, and someone comforts him.

But the next moment, another monk was attacked, and the monk screamed, and then covered his left shoulder, which was constantly burned by demonic blood, and then left a large hole.

"This demon blood arrow is too fast, I've already found it, but it's too late to dodge!" The monk immediately swallowed a pill of rejuvenation, but still felt pain.

Everyone couldn't help but be careful, although the copper essence is very precious, it is not worth losing their lives for this.

"Poof!"

Another demon blood arrow erupted, but it was dodged by Xiao Niansheng, and the demon blood fell to the ground and immediately burned, and a large hole was corroded on the ground.

"Strange! Why didn't this demonic blood corrode and burn when it was sealed? Qin Di asked, this demonic blood can clearly corrode even the ground, but why can it be sealed in the rock wall intact?

"But even if it's a demon king, it can't live for millions of years, right? Millions have passed since ancient times, and the Demon King will not live until now. "A monk doesn't think it's anything strange, if you only need to deal with this demonic blood, that's fine.

Xiao Niansheng didn't speak, he knew the demon clan very well, so he had the most right to speak, he knew very well that a demon king really couldn't live for millions of years, but if he was sealed in the Sun and Moon Divine Crystal, it was possible.

I hope I'm not so unlucky, if the Sun and Moon Divine Crystal is sealed with the Demon King's divine soul, then I'm afraid we are really dead.

The Sun Moon Divine Crystal that Xiao Niansheng got was only the size of a fist, but it was enough to seal the soul of a demon king, if the seal in this Sun and Moon Divine Crystal was really the soul of the demon king, and it was awakened because of the demon blood, then he would probably have to end the thousandth reincarnation here.

Xiao Niansheng and his party were still mining, although occasionally the Demon Blood Arrow rushed out, but because they were proficient in this Demon Blood Arrow several times in a row, they were not injured again, but the two injured monks before were more unlucky.

The most unlucky thing is still the loose cultivator, he is obviously the most cautious one, but in the end he was blinded by the demon's blood.

"Click!"

As they were digging, one of the monks seemed to have found something else, and he chiseled through the rock wall, and the bones rolled down with the dirt.

Everyone was shocked.

Dig out the bones!

Countless white bones rolled down, and everyone took a closer look and found that these white bones were relatively huge, and they were not human bones, and some were even bone fossils of claws and tails.

"Whoa!"

Suddenly, the rock wall that the monk had carved collapsed, and countless white bones rolled down, revealing a huge cave full of white bones.

"Something is wrong, what do you think it is?" The monk pointed to the mouth of the cave, and they leaned in, and then they saw a dark hall in the depths of the cave.

"Dig something out! It can't be the tomb of the Demon King, right? "A group of people felt creepy.

It's just a mine.,I actually dug up the demon king's grave.。

"This is most likely the palace of the Demon King, he was besieged and killed by ancient powerhouses, countless demon soldiers died here, and even he himself died here." Qin Di expressed his guess.

Xiao Niansheng pointed out, and the flying sword galloped away, breaking the rock wall in the blink of an eye, and more demon bones rolled out, but it also formed a path to the sea of bones.

"Guys, do you want to go to the big hall and have a look?" Xiao Niansheng asked.

"Just what I want!" The monk with the golden mace in his hand was the first to step on the sea of bones, he was full of courage, and he was not afraid of the bones of these demons at all.

"It's just a pile of bones." This monk didn't pay attention to these demon bones at all, but this is also, after all, they are just bones, what kind of waves can they make?

The others glanced at each other, and then followed, only the scattered cultivator said: "Fellow Daoists, I won't join in the fun, I want to stay here to dig up the copper essence." ”

This casual cultivator was more cautious, he had an ominous premonition about the dark hall, and his strength was weak, so he was not suitable to join in the fun.

The other monks nodded, and then followed the monk with the golden mace, they stepped into the sea of bones, and kept advancing, the cave was very large, and the top was also very high, they could fly with Edgeworth, but for some reason, none of them chose Edgeworth.

It's a very strange place, so it's best to be careful, as Edgeworth can easily become a target if it flies.

Most people think so.

They kept moving forward, and then approached the black hall, and when they got closer, they found that the hall was all made of some kind of black metal, and the metal surface was constantly flowing with strange patterns, which was very strange.

"How do these patterns move?" A monk couldn't help but make a sound, he felt his scalp tingle, how could this place reveal weirdness everywhere?
