The dungeon has been buried here for a long time, even the bones are rotten, in short, Xiao Yu has not found any traces that can prove the existence of people.

Can't prove it?

It's not true, Xiao Yu found that there was a strong death qi here, which showed that many people had died in this place, but everything was rotten because of too much time and the environment, and not even the bones remained.

Although Xiao Yu didn't find the corpse or anything, he still found the gray silver mine, which is located under this dungeon, fortunately, he used a mouse, and it is really impossible to sneak into a very harsh environment like a mouse to explore.

Since he found the gray silver mine, Xiao Yu certainly wouldn't let it go, and he began to dig up the entire dungeon. Xiao Yu was purely digging this gray silver mine, and he didn't care at all about what had happened to this dungeon. But when he dug up the dungeon, he found something amazing.

"There is actually a seal here, could it be that there is something special sealed underneath?"

Xiao Yu studied the seal, this seal should be a god-level seal, it should have existed for a long time, as for the complexity of the seal, he can see it clearly without even summoning the demon array master.

It's so dead.

Xiao Yu was very curious, this kind of death aura was very strange, it didn't seem to be caused by dead people, if his judgment was not wrong, this should be the purest death power.

Is there any death-based treasure down there?

Xiao Yu has studied the [Book of Death], he still has research on the power of death, this thing is completely opposite to the art of life, and the average life master will definitely hate it.

Xiao Yu studied the seal, it was not difficult for this thing to open, but he didn't try to open it, after all, God knows what was sealed below. What Xiao Yu was really surprised about was that the gray silver ore seemed to originate from under the seal, and if you wanted to look at the mining, you had to open the seal.

Can't open?

Xiao Yu didn't open the seal, although his strength is very strong now, it is better to be cautious about unknown creatures.

Xiao Yu began to get his hands on the gray silver ore that could be mined temporarily, which was still quite a lot, enough for him to research and develop flying machines.

"Brother Mu, do you know any cities in this swampy land?"

"City?"

Wooden easy rain boots surprised.

Xiao Yu: "Just now I dug up a city in order to dig up the gray silver mine, it seems that it has existed for a long time, and I also found a seal under the city, it seems that there is something very special sealed in this city." ”

Mu Yi said curiously: "This place seems to have always been a swamp, who would have nothing to do to build a city in a swamp, isn't it nonsense." ”

Mu Yi was very interested in the city that Xiao Yu said, so the two quickly came to the area where the dungeon was located.

"Brother, this ...... You made a big tree? ”

Mu Yi looked at the kendo Shenmu from afar with a confused face, this look is the Shenmu, the violent power of the kendo makes him have to trouble his scalp, this seems to be a terrifying sword god.

"I planted it yesterday to make a solid hole, and it works so well that I wouldn't have dug up that dungeon."

Mu Yi looked at the Kendo Divine Tree that was tens of meters tall and was silent for a long time, he really couldn't imagine which kind of life technique could cultivate a Kendo Divine Tree in such a short period of time. Now Mu Yi believed that Xiao Yu would be able to improve the environment in this area, if he planted a few more of these sword path divine trees, he felt that this place would soon become a holy place for swordsmen, and it was guaranteed that many swordsmen would come here to cultivate.

The two of them went down to the dungeon, where the smell of rot had dissipated a lot after so long. Although Mu Yi didn't have any expression on his face, his heart was shocked, planting a Kendo Divine Tree was very exaggerated, and Xiao Yu actually let the roots of the Kendo Divine Tree weave a passage, this operation was too sassy, he couldn't imagine what kind of life art cultivation could be done.

The two of them soon appeared in front of the seal, although Mu Yi was not a formation mage, but as an eight-rank immortal master, he was still well-informed, especially when he looked at the dungeon, he was a little surprised: "This dungeon should be the architectural style of 10,000 years ago, so it has been in the underground for at least 10,000 years." If it were 10,000 years ago, I would have heard rumors that someone had opened the passage to the realm of the dead, and countless creatures from hell had come out and turned large areas into swamps. ”

"So, it wasn't a swamp a long time ago."

Xiao Yu was a little stunned, he understood why there was a strong power of death here, and he felt that this was the passage to the world of death.

"It seems that the legend is true, this seal should seal the passage to hell, but fortunately you didn't open it, otherwise opening the door to the realm of the dead would have caused a terrible disaster."

Mu Yi's face was solemn.

Xiao Yu was curious: "What is this death country?" ”

Mu Yi frowned and said: "There are rumors that it is the place where death will return, but I don't know if it is not." ”

Xiao Yu blinked, it is difficult to say whether it is the place where death will return, but one thing is certain, if he needs to look at the gray silver mine, he will need to enter the realm of death. For the time being, it seems that there is no need to enter it, Xiao Yu still remembers that when he resurrected people, he met an ugly woman in the place of death, she should be a high-ranking divine master, and her strength is very terrifying. But now Xiao Yu is no longer what it used to be, if he unlocks the seal, he should be able to make a move with that ugly woman.

Of course, after all, this is a passage to the realm of death, and Xiao Yu thinks that there may be a Venerable inside, so it's better not to open it.

"Looks like we're going to have to seal this place again."

Xiao Yu frowned slightly, God knows how long the seal of this place can last, after all, it must have been corroded in such an environment, otherwise there would be no power of death overflowing.

"That's for sure, it's a pity that I'm not good at sealing, so I need to invite a god-level array mage to come."

Mu Yi's face was solemn.

Xiao Yu said with a smile: "There is no need to invite a formation mage, the junior brother is good at sealing, and the divine array is still not a problem." ”

Mu Yi was surprised: "Brother or Divine Array Master?" ”

Xiao Yu smiled: "Learning the formation is just a hobby, I am actually an authentic life magician. ”

The corners of Mu Yi's mouth twitched fiercely, he found that he couldn't understand it anymore, Xiao Yu didn't fight no matter how he looked at his age, it was already very exaggerated to become an immortal master, and now he was still a divine array master, how could it be.

Xiao Yu didn't say anything, he began to study the seal in front of him, no matter how he dug it out, he had to do things from the beginning to the end.
