Outside Yuanci Mountain, No. 4 sat on the ground and closed his eyes to rest.

On the seventh floor, he saw Yu Ziqing's message. After thinking about it, he felt that the mountain of mourning sounded familiar. He must have heard of it before.

"I've heard about Mourning Mountain. I need to go home and check the information. I'll get back to you in a while."

Yu Ziqing was a little surprised when he saw the message.

He didn't expect No. 4 to give him any information. For a guy like this who takes risks every day, if you ask him about the Dali Court, he will definitely not know.

He probably knew something related to the adventure, so he asked casually.

Unexpectedly, No. 4 had actually heard of it.

This means that the cave that Lei Yu wants to explore is definitely not simple.

Cave Heaven and Blessed Land are also resources that many big forces control.

Many of the special products in the Cave Heaven Paradise are not available outside. Minerals, elixirs, gems, monsters and other creatures, even ghosts, zombies and other undead spirits, everything can be regarded as resources.

Just like the flying boat produced by the Tianji Sect, the core part, some of the minerals and gems needed, can only be produced in a large cave under their control.

However, Cave Heaven and Blessed Land are not that rare. The only ones that are rare are Cave Heaven and Blessed Land that are of high value and suitable for development.

Just like the previous Jinlan Village, it can be regarded as a blessed place, but the only thing valuable to outsiders is the Jinlan Mine.

Before the Daqian Langya Institute had thoroughly studied the uses of Jinlan ore, Jinlan ore was just a useless product that was expensive, had extremely low yield, and could be completely replaced by low-priced ore.

Coupled with the supernatural power shrouding Jinlan Mountain, it can be said that it has no development value on the whole.

There are many similar blessed places, and every now and then someone will discover a new blessed place.

Most of them are of no use and have no development value. If they are shrouded by supernatural forces, their value may not be as good as the wasteland in the wilderness. At least some wasteland can be used to grow something after it is developed.

Blessed lands are generally smaller, but caves are generally much larger. They generally have a complete water vapor cycle, and some have even evolved unique creatures.

There will be relatively more caves worth developing, but their dangers will far exceed those of ordinary blessed places.

In addition to environmental dangers, there may also be dangers caused by the living and undead inside.

Generally speaking, Cave Heaven Paradise is not that rare.

Why did Lei Yu end up with a cave? That's because a cave with such protection is most likely to be much more valuable than a cave like a public toilet where anyone can come and leave as they please.

Similarly, because the caves are not that rare and there is too much garbage, other people are not very interested.

After all, that kind of protected cave must have been left behind by our ancestors.

Among our ancestors, there are quite a few who are evil-minded, have evil tastes, and like to do things that are harmful to others and not beneficial to ourselves.

I specially found an extremely dangerous cave, then built a lot of protection and sealed the entrance to trap people.

It's not like this has never happened before.

There are also some ancestors who did not have any burial objects when they died. They just used a cave as a mausoleum. Therefore, the arrangement of killing one step at a time and killing each step at ten steps was also a normal operation.

Yu Ziqing was not very interested in Lei Yu's invitation to form a team, and the reasons were related to the above.

At home, I went to Bai Yu Hua Tomb every day to maintain my health. After I was done, I continued to practice and practice. Almost a month passed in the blink of an eye.

There are no years of practice, and Yu Ziqing only feels that time is like running water, passing by in the blink of an eye.

Today, I finally received the message from No. 4.

"The information you want is a bit complicated and a lot. How about an interview?"

Yu Ziqing thought for a while and entered the seventh floor.

Number 4 is already sitting in his seat waiting.

"I dare not say anything else. If you ask about forbidden places, caves, blessed places, etc., I will definitely know more than others."

Yu Ziqing stretched out his hand to signal, asking the other party to start performing.

"In the Hengduan Mountains where the earthquake occurred, there are many caves and blessed places.

However, blessed lands are basically useless. They have been eroded and infected by the cold air of the Hengduan Mountains. They are not much different from the environment in the Hengduan Mountains.

Although there are fewer caves, they are generally some of the most extraordinary caves.

You should know that in the ancient times before the Great Earthquake, Great Li, and Great Qian were established, it was very popular to use the cave sky as one's tomb.

For those strong people, turning a cave into their own resting place is the most basic configuration.

They will specifically find some caves that are inherently dangerous and strengthen them before they die, turning them into a place of death and no life."

Yu Ziqing nodded seriously and motioned for No. 4 to continue.

He knows shit about history.

What he knew most about the past history was actually the things he had seen while tracing back the memories of Our Lady of the White Sun.

Study history and want to understand what can be accomplished in a short period of time.

"Originally, after I got home, I looked through the information and asked the elderly at home.

It is almost confirmed that the Mourning Mountain you mentioned does have a cave.

And it is most likely the tomb of a powerful man from ancient times.

The protection of the portal there is very strong, connecting the power of the entire cave and turning it into a whole. If it is forcibly broken open, the entire cave may be destroyed.

Am I right?"

Yu Ziqing nodded, Lei Yu indeed said that.

Therefore, unless the Li Ancestor of the Lei family takes action himself, he can control his power to the extreme and only penetrate the protection without harming the cave.

Or, use Wu Shuangge's Hunyuan Golden Dou to use foul air and toxins to corrode and dissolve part of the protective power.

As long as the erosion is rapid enough, a hole can be opened before the power of other parts is transferred, allowing people to enter.

And this kind of power will not allow the entire cave to bear all the blows like a forced blast.

"That's right, it's a place of mourning.

I advise you not to go. More than one wave of people have been there a long time ago.

An ancestor of my family went there a long time ago.

According to the records, there is a strong supernatural power permeating the place, which makes it difficult to refine the energy. In addition, the evil energy is rampant and evil spirits are everywhere.

The ancestor of my family left his ancestral precepts and mourned in the sky. It is the tomb of a terrible and powerful man. The descendants are not allowed to go and disturb it."

Yu Ziqing almost laughed out loud.

You can tell from you what your family is like.

How can a person who travels to forbidden areas every day, explores caves and blessed lands, and is away from home all year round, say such a thing?

The ancestor of No. 4 must have been taught how to behave there.

So I told you not to disturb me when you come back.

If you hadn't been severely beaten inside, your ancestors might even have dug up the ashes of that strong man to see if they were of any use.

What No. 4 said was a bit embarrassing. His family knew about his family affairs, so he immediately changed the subject.

"Of course, that's because my ancestor was only at the sixth level when he went to explore the Cave of Sorrow.

Otherwise, there must be more than just this bit of news.

Although no one has ever been to our house again, this cave of sorrow has been paying close attention to it.

I know that Lei Shi, who suffered a major earthquake recently, seems to be preparing to explore.

They were not the first wave to go either.

As early as more than a hundred years ago, Dali Lihuoyuan had reached a cooperation with the prince of Daquan and went to explore it together.

But that time, they all suffered heavy losses, and two ascetics died among them.

It is said that a shadow user died in Dali, as well as a chief who was second only to the shadow leader at that time.

The rest of the people were also injured.

Later, people who heard about the earthquake said that a dead spirit was disturbed there and almost killed them all.

They paid a huge price to seal the undead spirit.

After they came out, they also specially strengthened the protection of the entrance to the cave.

For more than a hundred years, no one has been there again.”

After No. 4 finished speaking, he thought about it.

"That's probably it. I don't know the more details."

"Thank you." Yu Ziqing cupped his hands to express his gratitude.

"You're welcome, the information you gave me saved my life, but the information I gave you is actually not worth your information.

If you have similar questions in the future, feel free to ask me. I may not dare to tell you anything else, but I will know more or less about this kind of question."

Adhering to the principle of speaking as little as possible, Yu Ziqing said goodbye to No. 4 and left the seventh floor.
