Gray silver, this is a special mineral that seems to have no effect, at least Mu Yi doesn't know what this metal is for, and the reason why he takes it out to trade is to try his luck. Of course, although I don't know what the gray silver is for, but this thing contains power, but this kind of power Mu Yi has only encountered in the gray silver.

Gray silver is an ore that doesn't seem to have any characteristics, and if it weren't for an accident, Mu Yi wouldn't have gotten this kind of thing. Originally, he was just holding it to give it a try, but he didn't expect Xiao Yu to be so interested.

"Where can this gray silver mine be mined?"

"What's the use of this stuff?"

Mu Yi asked quietly.

Xiao Yu smiled: "For the time being, I don't know very well, but I just feel that it should be useful to me, of course, if this kind of thing is difficult to obtain, forget it, it's not a necessity anyway." ”

Mu Yi raised his eyebrows and said, "This kind of thing is not very difficult to obtain, as for how many are not very clear." ”

Xiao Yu smiled: "In this way, if there are enough gray silver mines, I can help you change the environment here." ”

"Transform the environment here?"

Mu Yi was stunned, he didn't understand the meaning of Xiao Yu's words.

Xiao Yu said with a smile: "As a life master, what I am best at shouldn't be the ecological environment of a place that changes my life, has Brother Mu never considered such a thing?" ”

Mu Yi shook his head and said, "The environment of this place is not suitable, otherwise I would have tried it a long time ago." ”

Xiao Yu said with a smile: "I think it's quite suitable, the matter of transforming the environment can be handed over to the junior brother, and now Brother Mu can tell me where there is a gray silver mine." ”

Mu Yi finally told Xiao Yu where there was a gray silver mine, although he didn't believe that Xiao Yu had this ability, but he still had the mentality of taking a look.

The swamp is not ordinarily large, and there is no end in sight, even Xianwu, who can fly in the sky, is reluctant to come to such a place, because if you don't find the right direction, you will definitely get lost here. However, these did not exist for Xiao Yu, and now he released the mechanical eagle, which could cover a radius of hundreds of miles, and it was basically impossible to make a mistake.

The gray silver mine is a hundred miles away from the Destiny Tower, which Mu Yi accidentally encountered when he ventured. If there is ore, there must be a mountain or something, but this is a swampy area, and this kind of thing definitely does not exist, so it is a very strange place for gray silver mines to appear here.

Xiao Yu soon came to the place where the gray silver mine was discovered, this is the swampy land, he found that it is easy to sink here, and at the same time, there is a very special plant in the whole area, a radius of hundreds of meters is covered by a plant, but this plant is not standing directly on the surface, his root system is rooted in the ground, as long as it is close to this area, all the root systems are like a net, the living things are trapped, and they will soon become their food.

Xiao Yu received an attack when he arrived, but it was a pity, for a sword god, this little thing was still not enough, he directly released hundreds of immortal swords, and all the roots that rushed out were crushed in a flash of lightning.

Xiao Yu soon discovered a few gray silver mines, which made him very puzzled, it stands to reason that there should not be such an ore here.

Could it be that the plant was brought out of the ground just now?

This is still very likely, which means that there must be gray silver mines in the depths of this swamp.

What to do?

There is definitely no way for ordinary people to encounter this situation, but Xiao Yu has many methods, his choice is simple and rude, and he directly intends to hollow out this area.

Xiao Yu didn't get the digging robot out, but took out a seed of a kendo divine tree and planted it, and then used the word life technique to forcibly let this divine tree grow. Xiao Yu activated the Divine Witch Order, but he had the divine power of a divine master, and then began to use the Word Destiny Technique. Soon the Kendo Shenmu Zhuzhuang grew, originally just a fruit, and soon grew into a big tree in the sky. The root system of the Sword Dao Divine Tree was very domineering, and all the plants in this area were originally crushed by the sword qi.

The Kendo Divine Tree is getting bigger and bigger under Xiao Yu's control, it not only absorbs the power of the life technique, but also devours the nutrients in this area, half a day has passed, a Kendo Divine Tree with a height of tens of meters has appeared, its root system is rooted in a radius of more than ten miles, it is definitely a behemoth.

Xiao Yu did this for a reason, after all, the soil in the swamp was too weak and soft, and it was difficult to dig a cave directly, so he needed the Kendo Divine Wood to fix the entire area and forcibly create a huge cave that could lead to the depths of the earth.

The function of the Sword Dao Divine Wood is to create a cave for Xiao Yu, which is very easy, and the appearance of a cave of thousands of meters makes him very surprised.

This alone is not enough, after all, this is a swamp, and if a cave appears, it is likely that the surrounding groundwater will seep through. This is not difficult for Xiao Yu, he directly used natural spells to turn all the soil into rocks, and it was easy to create a perfect cave.

After spending most of the day, Xiao Yu finally made a cave that extended deep into the ground, and what surprised him was that this area was not a mineral vein, but a stage dungeon, but it seemed that it was all soaked in muddy water. No matter what this place used to be, Xiao Yu had to dig out this dungeon, which was soaked in muddy water, so naturally he had to evacuate all this muddy water. This is very troublesome, and Xiao Yu's final method is to let these muddy water condense and then transport it out. Fortunately, there was a digging robot, and after wasting a day again, Xiao Yu finally got rid of the muddy water in the dungeon.

"What's here?"

Xue Wanru 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."

Xiao Yu released the mechanical mice used for detection, which made several beauties who came in very disliked, and they all condemned him for getting something that didn't look scary in the future.

Xiao Yu shrugged, rats are the best choice in such a place, what do these women know. Although he complained in his heart, Xiao Yu 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 Xiao Yu found that there don't seem to be any plants that can improve the air in the plants he collected, and it seems that he must prepare such plants in the future, even if it is not very useful, but when it comes to using it, it is still very practical.
