……

The domain of the night, at 11:32 p.m., at the heart of the West Mountain.

Under a collapsed mountain peak, there is a huge underground palace mausoleum, and it is not known what is buried.

Xu Mu and his party have been digging for a long time, and there is only one point left, which can completely open the passage to the main tomb, so everyone can't help but get more and more energetic.

"It's the last layer, let's do it together!"

Between the narrow passages where the Hokage swayed, the five of them were huddled side by side, and Xu Mu threw away the shovel, his eyes suddenly sharpened:

"Three, two, one, kick!"

When the last word fell, the five of them used all their strength to kick directly on the thick earthen wall almost simultaneously.

Bang!

Under the kick, the soil layer that was only less than two meters thick was completely kicked open, and what came into view was the space of the black hole.

Everyone was overjoyed, and immediately poured into it, but they were pulled by the eldest grandson Weiying and Xu Mu at the same time.

"Wait!" , the two of them spoke at the same time, and one hand grabbed one person.

"Be careful, there will be danger, usually in this kind of mausoleum, there will be a mechanism."

"Wasn't the mechanism touched by the gang before?"

Liu He held the torch and leaned out half of his body, he was a casual cultivator, this level of opportunity was something that could change his fate for a lifetime, but now that someone was pulling him, how could he not be in a hurry.

"I don't feel any special fluctuations, I can go and see it."

Charles opened his mouth and said, Xu Mu breathed a sigh of relief:

"Let's go, it should be safe."

As he spoke, he let go of his left and right hands, and everyone rushed in.

"What a big mausoleum."

Liu He and Xu Mu each held a torch in their hands, Liu He stepped into this space one step ahead of him, and had already walked dozens of meters away, but he still couldn't let the torch shine to the end, and even they had a long echo when they spoke.

The passage was full of dust, but it was unusually clean, as if the dust had been swept away.

Xu Mu frowned, stepped into this space with a solemn face, and then drank softly.

"Hah!"

Everyone was frightened by him, especially the two timid twin fat men, who thought that Xu Mu had suddenly gone crazy and was going to do something to them before the chance.

"The speed of the sound is about three hundred and sixty meters per second, I let out a low shout, two long and wide, and the farthest echo is in six seconds and four seconds respectively, that is to say, the length of this main mausoleum is about more than 1,000 meters, the width is about 700 hundred, and even if the height is 30 meters, this is more than 20 square kilometers......"

Xu Mu ignored everyone's gaze, but silently calculated carefully in his heart.

Then, he was shocked by the number.

"Twenty square kilometers is spread out, which is equivalent to 30,000 acres of land, and the total grain production area in the Strange Night Domain is not estimated to be so large."

"If a complete ancient mausoleum has such a scale, Xu Mu can accept it, after all, Charles told him that there was an emperor's mausoleum on the Blue Star, which occupies more than fifty square kilometers, but that is also the total area."

"These twenty square kilometers are just the main mausoleum, how big is this underground palace?"

……

"Did you notice...... This space seems to be getting brighter and brighter? ”

Without waiting for Xu Mu to understand, Liu He, who had walked the farthest, put down the torch with a strange expression, because he found that this huge space seemed to be slowly becoming brighter, although it was still very dark compared to the day, but it was indeed much brighter than before.

I don't know what the reason is at play, because there are no torches around, but they are slowly brightening, as dim and dull as before the sun rises.

"There seems to be some kind of special substance in the space, and I don't have the instruments to break it down."

Charles said.

"There's absolutely weirdness and damnness about this place."

Xu Mu inexplicably began to get nervous, what are the unknown secrets of this big bizarre but empty mausoleum?

"This ...... This ......"

The fat man had tripped over something in the dark before, and it wasn't until it was lit up that he could see that it was a few terrifying white bones!

"There are only bones left, and it looks like they've been dead for years."

His brother stepped forward, looked at it casually, and then said.

"No, this corpse is indeed white bones, yes, but you look under him." , The eldest grandson Weiying found the clue, he squatted down, picked up the pile of white bones, and took out a brand new book from it.

"Luo Dao Daodian!"

The young man's eyes trembled, he knew this book, this was clearly the Dao method developed by a third-stage powerhouse in the Hunter Alliance on the other side of his sea area, why was it here?

"There are bones over here, too."

"There's that too!"

In a moment, several people found countless white bones in different places, all of them were only bones, and all the flesh and blood were gone, as if they had been dead for a long time.

The eldest grandson Weiying's body was numb, and he suddenly thought of something extremely terrifying, could it be that these white bones were not the people who accompanied the burial before, but the strangers who died here a few days ago?

"Thirty-one, thirty-two, thirty-three, thirty-...... Four. ”

Xu Mu stood in the distance, his shadow ability roaming freely in this mausoleum, seeing all the white bones clearly.

Thirty-four white bones prove that thirty-four people have died here.

Well...... Before, the eldest grandson Weiying said, how many people are in that loose cultivation team?

Before Xu Mu could think about it, there was a huge roar in the space in front of him.

"Boom, boom, boom......!"

The stone bricks of the entire underground palace were trembling, everyone was shocked, and at the same time, they looked ahead, only to see a high platform in the shape of an altar, slowly rising, dragging a coffin sealed with iron chains, wrapped in countless circles, as if there was something terrifying sealed inside.

Such a change calmed Xu Mu and the others, and they either looked at them solemnly or fearfully.

But only one man, still walking towards the altar as if enchanted, was less than twenty paces away.

"Stop, you're crazy?" , the eldest grandson Weiying tried to stop him, but the young man did not react, his body was like a puppet, and he kept moving

"Horse's!" , Eldest Sun Weiying gritted his teeth, a goshawk-like sharpness appeared in his eyes, and his whole body surged, as if he was hesitating whether to step forward to stop him.

Xu Mu stared at the altar, feeling as if he was inexplicably attracted, so frightened that he hurriedly looked away.

"That team consisted of scattered cultivators, a total of thirty-four people, after coming to the core area of Xishan, they found a mausoleum, entered here, and they found many treasures."

"And when they opened a coffin sealed with chains, countless darkness erupted, and almost everyone died here, except for one who ran fast and one survivor who did not go to the grave......"

Xu Mu lowered his head, remembering the description of the eldest grandson Weiying, and filtered it from beginning to end, his brows furrowed.

He has been digging in this underground palace for a long time, and he has dug out the side rooms, and he has indeed found a lot of treasures.

But in those side tombs, whether it was a coffin or a box, it was all sealed and never opened.

But the problem is that in that story, those coffins and boxes should have been opened, and those scattered cultivators had obviously obtained very precious treasures.

And the coffin that the man said was sealed with iron chains, and they had only met this one.

If, in the end, it was because of its opening that the dark energy poured out, causing the changes in the West Mountain, then what is going on now?

Why is this coffin locked?

"Thirty-four men, thirty-four bones...... Why did two people go back to the city that didn't fall? ”

"Is it ......?"

Suddenly, Xu Mu thought of the humanoid domain master demon he saw when he entered the mountain, his pupils suddenly shrank to the extreme, and his expression changed drastically:

"Don't let him open the coffin!"

"The story is false, thirty-four people died here, and this burial chamber was never opened."

Xu Mu's expression was crazy, which made everyone feel frightened:

"Back to the ...... of the city that never falls It's not human at all! ”
