Qin Wu's ultimate method was to let the muddy water condense and then transport it out. Fortunately, after wasting another day, Qin Wu finally got rid of the muddy water in the dungeon.

"What's here?"

Xue Yuxue appeared in the dungeon, the environment here was very bad, exuding a strong smell of decay, after all, it was soaked in underground water, God knows how many years, everything that could rot must have already rotted.

"Who knows, I just wanted to find the gray silver mine, but I didn't expect to find a dungeon. ”

Qin Wu released the metal rats for detection, which made several beautiful women who came in very disliked, and they all condemned him for getting something that didn't look scary in the future.

Qin Wu shrugged, rats are the best choice in such a place, what do these women know. Although he complained in his heart, Qin Wu didn't squeak, he frowned, the air in this place was too bad, and he thought that he should try to improve the environment here.

Planting plants is definitely the first choice, but Qin Wu found that there didn't seem to be any plants that could improve the air in the plants he collected, it seemed that he must prepare such plants in the future, even if it was not very useful, but when it came to using them, it was still very practical.

The dungeon had been buried here for a long time, even the bones were rotten, in short, Qin Wu did not find any traces that could prove the existence of anyone.

Can't prove it?

This is not true, Qin Wu 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 Qin Wu 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 in an ordinary way.

Since he found the gray silver mine, of course Qin Wu would not let it go, and he began to dig up the entire dungeon. Qin Wu 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?"

Qin Wu studied the seal, this seal should be a god-level seal, it should have existed for a long time, and as for the complexity of the seal, it was easy for him.

It's so dead.

Qin Wu was very curious, this kind of death qi was very strange, it didn't seem to be caused by a dead person, if his judgment was not wrong, this should be the purest death power.

Is there any death-based treasure down there?

Qin Wu 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.

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

Can't open?

Qin Wu didn't open the seal, although his current strength is very strong, it is better to be cautious about unknown creatures.

Qin Wu began to get his hands on the gray silver ore that could be mined temporarily

, this is still quite a lot, enough for him to carry out the research and development of flying machines.

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

"City?"

Wooden easy rain boots surprised.

Qin Wu: "Just now I dug up a city 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 Qin Wu was talking about, so the two of them 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 in the ground, and it works so well that I wouldn't have dug 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 Qin Wu would be able to improve the environment in this area, and 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, he was shocked in his heart, planting a Kendo Divine Tree was very exaggerated, and Qin Wu 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 Land 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. ”

Qin Wu was a little stunned, he understood why there was a strong power of death here, and he dared to feel 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 it is good that you did not open it, otherwise the door to the land of the dead would have been opened, and it would have caused great trouble. ”

Mu Yi's face was solemn.

Qin Wu was curious: "What kind of place is this country of death?"

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." ”

Qin Wu blinked, it was hard to say whether it was the place where death would return, but one thing was for sure, if he needed a large amount of gray silver mines, he would need to enter the country of death. For the time being, it seems that there is no need to enter it, Qin Wu 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 strong. However, now that Qin Wu is no longer what it used to be, he should be able to teach if he unlocks the seal

This ugly woman is a man.

Of course, this is the passage to the country of death after all, Qin Wu thinks that there may be a top venerable inside, the martial artist is nothing, and if there is a good thing, the top life venerable will be terrifying, so it is better not to open it.

"Looks like we're going to have to reseal this place. ”

Qin Wu 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 ask a god-level array mage to come. ”

Mu Yi's face was solemn.

Qin Wu 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 is still a Divine Array Master?"

Qin Wu said with a smile: "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, Qin Wu was not very old no matter how he looked at it, it was already very exaggerated to become an immortal master, and now he was still a divine array master, how could it be.

Qin Wu didn't say much, 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.

It was not difficult to decipher the seal, and Qin Wu quickly got it done. But the real problem is that it is very difficult to rearrange the seal, the current environment is not suitable for superimposing one on the cause seal, according to Qin Wu's calculations, it seems that it will not work out no matter what.

Remove the original seal?

Qin Wu's idea was denied by him as soon as it came out, it was too risky to do so, even if he was a high-ranking Sword Venerable, he wouldn't dare to play like this, what if he ran into a Destiny Venerable, now he couldn't fight against Destiny Venerable.

"Is there a way for my brother?"

Mu Yi's face was gloomy, although he didn't understand the seal, he could also see that the seal in front of him was afraid that it was very inappropriate.

Qin Wu said in a deep voice: "This seal won't last long, if I don't open this place, maybe it will fail faster, and at that time, the power of the Dead Country will enter the second domain, which is really a disaster." ”

"Brother, can't you do it?"

Mu Yi's face became even more worried.

Qin Wu said indifferently: "Who said that I have no choice, but now I am considering which method is more appropriate." It's just a pity that either one has a lot of risk, which makes me hesitate. ”

Mu Yi was stunned and said, "How many ways does my brother have?"

"Not much, for the time being, I think of both, but both are very risky. ”

"Which two, let's hear them?"

Of course, Mu Yi didn't want the seal to be broken, he didn't want the second domain he lived in to become a dead domain.

Qin Wu: "The first method is very simple, that is, to destroy the seal, we will create a new seal from scratch, and ensure that it is stronger than the previous seal. ”

“......”

Mu Yi was silent for a long time before he said, "This risk is indeed very large, what is your second method?"

Qin Wu said in a deep voice: "The second method is much simpler, I plan to design a superimposed seal based on the existing seal, although it is very difficult, but it should not be a problem. However, there is a great risk in this method, once the first seal does not hold up, it may spread to the second seal, and it is difficult to say how long it will last. ”
