Generally, where there are volcanoes, in Xiao Yu's opinion, they are all barren, and the temperature of the earth fire is too high, so it is impossible for such a large ice cave to appear!

"What I said is true, I remember a news that there is such a place in a foreign country, one side is cold, and the other side is hot, people call it ice and fire, it doesn't seem to be a strange thing!"

"It's just that this underground fire vein is very small, and the location of this hot spring happens to be the intersection of the fire veins, so the hot spring will be formed here.

Besides, when you came in, you also saw that there is a river, such a large ice cellar, how many degrees are there, how can the ice melt? The only explanation is that there is a temperature down there that allows the ice to melt, so the ice cave will melt and form a stream. ”

Wu Xuan explained like this, and Xiao Yu understood.

What I saw before was not an underground river at all, and then the water that flowed out after the ice cave melted.

The water flows into a lake, and then provides some moisture to the large array outside, and so on.

Volcanoes do not erupt, glaciers do not melt completely, to a certain extent, icebergs and underground fire veins, the two restrain each other, and no one can help anyone, so it is a stalemate like this, and it will be thousands of years at a time.

"Tsk, it's amazing, such a perfect interface can be used, which predecessor before, it's really powerful."

Xiao Yu said admiringly.

"I also said that this water is very helpful for cultivation, but fortunately I didn't drink it, otherwise, I would have to drink other people's bath water!"

Xiao Yu turned his head and looked at the dragon's blood tree again.

If the pool is useless, then this thing should be a treasure, right?

Dragon's blood, that's a legendary existence, although this tree doesn't know what it is for, but it's definitely not ordinary.

"Ice silkworm, what are you doing, you think this is a bathhouse?"

As soon as Xiao Yu took two steps, he saw that the ice silkworm was swimming up and down in the pool under the dragon's blood tree, and the white thing in the water was actually smaller, obviously stolen by the other party.

There is also the water of the ice spirit, which is something that only Western women can enjoy in their mouths, and the ice silkworm is actually bathing in it, Xiao Yu dares to guarantee that he is the most awesome silkworm ever.

was scolded by Xiao Yu, and the ice silkworm climbed ashore from the water with a cleverness, lying there, like drowning, constantly spitting out water.

"I said Brother Silkworm, can you not bring such a play, I'm still waiting for you to make a contribution, you're good, this drink is vomiting and diarrhea!"

Xiao Yu was distressed, the white thing in the water, although he didn't know what it was, but the thing that could appear in this divine water was definitely not ordinary.

And the toad is in it, trying to pollute the pool water, and the venom is absorbed by the white thing, which means that that thing is extraordinary, and it is super extraordinary.

"Tsk, Xiao Yu, you are really lucky! When I used to know Tianyue Daogu's master, he found this kind of ice spirit water in an ice cave, and after drinking it, he broke through his cultivation and lived for several more decades.

But he only has a little bit, and you're a big pool, amazing, amazing. ”

Wu Xuan said with envy.

"What is this?"

Xiao Yu stretched out his hand into the ice spirit water, touching the snow-white thing, like a meat lingzhi, and like a piece of jelly, it was very slippery.

"This, I don't know, I haven't seen it, but it should be a good thing to grow in this kind of place."

Wu Xuan, who was well-informed, was also stumped and immediately shook his head.

Xiao Yu was not disappointed, anyway, this thing can grow in this kind of water, it must be a good thing.

"Xiao Yu, this place is blessed, one hot and one cold alternately, and there is also ice spirit water here, you have to build the mountain gate to the top, and the disciples under the door will definitely cultivate very quickly in the future, at that time, this is your retreat place, isn't it very good."

Wu Xuan said what he thought.

When Xiao Yu heard this, he couldn't help but nod and said, "You're right, but building a mountain gate involves a lot, although this Miao Jiang seems to be calm, maybe there are still many hidden forces below, and they need to be figured out!" ”

"Yes, this ice spirit water is the essence of the iceberg, even if it is an iceberg in the Arctic, it may not be able to cultivate such a thing, so you have to protect this thing, if it is known by other people, it will definitely come and rob it."

Wu Xuan admonished again, looking very solemn.

"Wu Xuan, I want to move him to the ancient jade, do you see if it can be done?"

From the beginning, Xiao Yu has been paying attention to this, and now he also wants to listen to Wu Xuan's opinion.

"Well, you can try, but it's better to leave a little bit for future generations, now there are too few genius treasures, and each one takes a thousand years or even longer, and it can't be broken at one time, which is not good for future generations."

"Okay, you go and get a place first, there are ice silkworms here, which can ensure that the ice stone does not melt and can be well preserved."

As Xiao Yu spoke, he put Wu Xuan away, and he himself took out some utensils and began to pack all the ice spirit water, including the big jelly-like thing, which was also put into the ancient jade by him.

Of course, he did not earn all of it, but left a small part, which is like a seed, put it here, he will grow, if not, then it will be lost!

Of course, there was also the dragon's blood tree, which was also dug up by Xiao Yu.

The woman was right, there was indeed a red dragon's blood stone under this dragon's blood tree, but Xiao Yu didn't have time to study it now, so he could only put it away first.

All the things were put into the ancient jade, and the guardian ghost general began to put those things in the place where the ice silkworms lived, and at the same time, Xiao Yu dug a lot of ice cubes and piled up an iceberg directly in the corner, which looked very powerful and magnificent.

After everything was cleaned up, Xiao Yu nodded with satisfaction, grabbed the small fish caught by Caidie in his hand, and quickly rushed to meet Qinglong and them.

As for Qinglong, after separating from Xiao Yu, they kept moving forward, but they didn't dare to go too far, because no one knew what was in front of them, after all, the tomb of Daxian was not the tomb of an ordinary person, it couldn't be just some ghosts, as well as zombies and other things.

"Everyone wait for Xiao Yu to come back, don't leave."

The green dragon stretched out his hand to stop everyone from moving forward, because in front of them, a lake nearly fifty meters in size had already appeared.

In an underground karst cave, a lake nearly fifty meters in size appeared, which already occupied all the karst caves, so if you want to pass, you must go through the lake, otherwise you will not be able to pass.

The lake is so turbid that the naked eye can't see through the clear water, and even if one of the green dragon's eyes turns golden, it still can't penetrate the turbid water.

For this kind of unknown place, Qinglong has always been more cautious.

For ordinary people, this may be a lake, but for monks, it is possible that there are countless monsters hidden underneath.

For example, the human-eating python, the kind of fish that attacked Xiao Yu, and some water ghosts, etc., will devour everyone's lives in an instant.

"Qinglong is right, the lake here is turbid, don't enter it easily, I ......"
