Li Feng waved his hand to summon the ghost flag planted on the ground, and asked it to get close to the tomb filled with black light, and sure enough, the black light was great, and this ghost flag was related to the tomb below, maybe it was a key or something.

He struck out with a palm carrying spiritual power, and tentatively slapped it towards the tomb, but in an instant, the black light of the tomb gathered, and he easily blocked the palm with the light of the righteous path, and bounced his palm back.

Under the tomb, maybe there are some evil demons and monsters hidden, rashly open the seal, if this can't be solved, then a big disaster, can only be left by the big murderer to escape the outside world.

Li Feng couldn't accurately judge what kind of cultivation the murderer under this tomb was, but on the surface, it was actually an ordinary ghost mansion.

If it was before, Li Feng would have entered recklessly, anyway, there is a sect behind him, and there is a high top when the sky falls, or I am afraid that the world will not be chaotic.

But not now, he didn't find any other survivors of the end of the law for the time being, maybe it was the only hope for the cultivation world in the new era, if he died recklessly, it would be a shame for the ancestors who died in the end of the law era, and a shame for the ancestors of the Qingling Sword Sect.

And the important thing is that there is no one behind him to help him, he hangs up, if this great murderer runs out of the outside world to harm the mortal world, it will be sorry for human civilization.

Therefore, it seems to be a simple question, whether this tomb will be opened or not, and it will be implicated in a far-reaching matter, and it will be related to the major events that affect the rise and fall of the human race.

But if Li Feng does not open, and this tomb is still left here, and the black light is overflowing, then it is difficult to say that there will be no ghosts running out of it to harm people, and sooner or later something will happen.

After thinking about it, Li Feng took out a few pieces of yellow rune paper from his arms, used the sword finger as the pen and the true yuan as the ink, and drew the runes on the paper, and the runes were on the yellow rune paper less than ten inches.

That's right, he plans to seal this place, which is the safest way, because this place is too close to the living area of ordinary people, and it is difficult for him to guarantee a stable victory, so in order not to affect ordinary people, he can only do this first.

In the future, when the Tao is profound, or the seal can't hold up, he will deal with it again, and the risk will be lower.

In addition to drawing the seal talisman to ward off evil spirits, Li Feng also moved a lot of boulders from nearby as a formation, and moved groups of ancient trees to the deep forest in the distance to suppress them, and also dug several small lakes near the tomb to add the finishing touch to the sealing array.

Originally, he also wanted to set up a huge glass bowl above the tomb to focus light on the tomb to achieve the purpose of strengthening the seal, with the Five Elements Sealing Array.

But I really don't have that condition, and I don't have that ability, so I can only give up for the time being, or make up for it later.

Everything is ready, the ground near him has been flattened by him with boulders, and he also used some catalytic agents to quickly produce some grass, the dog has already cleaned up the nearby carrion foam into a pile, and was burned into ashes by Li Feng's sword fire, just waiting for the moment when the sun came out, the yin qi of the tomb decayed, and the evil charm was pasted ......

......

Hmm, what tomb suddenly opened? But he hadn't had time to seal it yet.

Li Feng couldn't figure it out, he hadn't done anything, and no one had touched the tomb, and the ghost flags were all fine, but the tomb was open on its own.

This is the strangest thing, could it be that the murderer under the tomb has been revived, or is it that Li Feng's actions here have broken the original seal of the tomb?

But after waiting for a long time, Li Feng still didn't see any big murderers come out, and the tomb & cave entrance was still black and fluttering, but it was dawn, and it was not as strong as before.

Let's go in and find out......

The dog howled, yelling to go in, this time Li Feng didn't stop it, the little murderer doesn't have to run, the big murderer can't run, it's better to take it in, maybe you can also experience it, if it's really dangerous, let the dog attract attention, he can run first.

A man and a dog entered the tomb like this, and Li Feng also carried a ghost flag.

There is no ladder at the entrance of the cave, it is a simple and direct drop into the hole, the hole is pitch black, the yin qi is deep, and the five fingers are not visible.

It was about 100 meters down from the entrance of the cave before it fell to the ground.

Li Feng's fingertips lit up a sword fire, illuminating the gloomy cave, startling a large group of cave bats, he observed the surroundings, the cave interior was vast, the structure was intricately complex, and there were many crystals of special minerals in the cave.

But there are no demons or monsters, and even the only creature visible here, bats, are just ordinary cave bats, which look like ordinary underground caves.

But the dog, who was originally barking on the outside, now smelled this strange silence, and no longer barked, and he didn't dare to gasp.

If it weren't for the vigorous yin aura in this place, coupled with the sky-high black aura at the entrance of the tomb and cave before, Li Feng would almost think that this place was an ordinary underground cave.

And there is also a suspicion that there is an ordinary cave under the tomb?

It may be the ancestors of the cultivation world, sitting here.

This is Li Feng's idea.

Walking towards the depths of the cave along the direction where the yin qi is most vigorous, Li Feng is fine, but the dog has already begun to tremble, this dog's legs are shaking step by step, step by step.

Li Feng was very puzzled and asked, "What's wrong with you?"

The dog whined a few times, roughly meaning that there was an aura in the depths of the cave that made its heart tremble, and it seemed to come from the suppression of the blood.

"Could it be Erlang God or Roaring Heavenly Dog, or is the Great Heavenly Dog buried here?" Li Feng was stunned.

The dog didn't know that this had touched its blind spot in knowledge, but it just couldn't help but be in awe, as if it wanted to surrender to the owner of that breath.

Li Feng couldn't help but give it a slap on the head, "If you are against you, you will smell someone else's fart, and you want to change hands?"

The dog whined aggrievedly, and then continued to follow Li Feng forward.

The cave rises and falls in a wavy line like a stock market, but it continues to fall again and again, and after extending downward for dozens of miles, it is finally coming to an end.

And the further back, the more the yin qi becomes, and even the wisps of it can be seen like thoughts, and finally to the end, there is actually an underground lake formed by the accumulation of yin qi into liquid.

"Could it be that this yin vein is the source of the thick yin qi?" Li Feng looked at this liquid yin lake, very surprised.

This kind of yin vein, in the cultivation world, is also called yellow spring water, the legend is that it flows from the underworld, but if you look for it, you can't find the root, so most of the scholars in the cultivation world are more inclined to the yin vein is naturally formed.

"Is it the Yin veins here that nourish the burial ground above?" Li Feng muttered to himself.

No, if that's all there is to it, how can the black light of the tomb be explained, and how will the ghost flag react with the black light?

Is it because it's dawn? That's why the real tomb here is hidden and buried?

What was the dog afraid of? Who was that breath it feeling?

Is the special topography of the burial ground also related to this?

Li Feng was plagued by many questions, but he couldn't figure it out......

At this time, he was disturbed by the barking of the dog, and when he came back to his senses, he saw the dog barking at him, and then skimming the bottom of the underground lake with the dog's head.

Li Feng followed the direction it was pointing to, stared intently, and really saw that there was a hidden hole at the bottom of the lake, which he hadn't even discovered before!?

He began to rejoice a little that it was right to bring the dog in.

Li Feng jumped into the yin lake with the dog, the lake water was cold, and it was different from ordinary ice water, this kind of coldness was not something ordinary people could bear, it felt like jumping into liquid nitrogen.

The dog can barely bear it.

Swim downstream to the hidden hole that the dog found, the hole is not big, almost the size of a watermelon, but it is bottomless, and Li Feng can't find out how deep the hole is.

After swimming more than 20 miles inward, the dog almost couldn't check it, or relied on Li Feng to cross the aura to it, barely supporting.

Suddenly, the field of vision was broadened, and at the end of the waterway was another yin lake!

But this yin lake, in terms of morphology, is obviously much larger than the previous one, and this lake seems to be the main vein, because at the bottom of the lake, Li Feng also found the other eight undercurrents that hide the mouth of the cave.

The arrangement of these nine caves seems to be messy and random, as if it is naturally formed, but in fact, there is a hidden mystery, very exquisite, and it faintly presents the trend of nine dragon arch beads.

Outside the surface of the lake is a large natural giant cave, and on the other side of the Yin Lake, a stone door comes into view.

Li Feng and the dog looked at each other, and the dog didn't know if it was because he had been soaking in the Yin Lake for too long, or because it was close to the so-called breath, and the dog's body began to tremble again.

Swimming to the other side, they really saw that the pattern carved on the stone gate was not large, but the pattern carved on the door was detailed and clearly visible.

There are ancient gods in the pattern, there are demons and monsters, there are Huangquan Difu, there are also Tianqiong Palace, there are red dust beings, ordinary people, there are also Taoist cultivators, and immortals from outside the sky......

The richness of the pattern is that even the most delicate sculptor in the world will be ashamed and amazed when he sees it.

Whose tomb is this, just push the door in at this moment and you will know the answer.

The moment before Li Feng pushed the door, he instantly figured out something.

Nine dragon arches, yin veins, the mass graves in the cemetery outside, and those ghoul resentful spirits......

Judging from the era of ghouls and ghosts and ghost generals, it can actually be found that they have been preserved since ancient times, although they have died, but because of this, they have no aura, so they are not affected by the end of the law, and they can be preserved.

Looking at the Yin vein, as well as the Nine Dragons Arch Bead, and the stone gate here, it is actually not difficult to guess the truth, this may be the self-appointed resting place of a certain great power in the cultivation world to survive the end of the law.

Li Feng didn't know the principle, but he probably guessed that it should be with the help of the nine yin veins, to forge the Netherworld, or to fake the state of suspended animation, or simply use the corpse as the way to awaken a trace of spirituality, and then use special means to absorb the 'past life memory' prepared before the end of the law, so as to survive the end of the law......
