Chapter 977: Alien?

I have never seen such a cold before, even in the snowy mountains of Siberia, Li Tian did not wear clothes, nor did he feel this way.
What is in it?
He and Ghost King glanced at them, and were shocked by the scene in front of them.
A huge ice cave tunnel, the entire tunnel is filled with ice, and the surrounding stone walls are thick.
I don’t know how many years have passed. There were originally four-to-five-meter-wide tunnels, but at this time they could only accommodate one person to walk, all occupied by ice.
Such a thick ice layer, I don't know how many years it took to evolve.
Ghost King and Li Tian are actually a little unbelievable in their hearts. It's impossible. How could there be such a thick ice on this mountain?
It's not in an extreme place like Antarctica, nor near the equator...
Most of the extreme weather occurs in these places. The Miao Village belongs to the south. The temperature in the south has never been low, even if extreme weather is encountered this year.
Unless... there are some treasures in it, although it sounds a bit mysterious, but for the realm of the ghost king and others, they know that there will be something very cold, which will freeze the surrounding water vapor.
For example... Xuan Jing!
This is a natural thing, and it can also be chemically synthesized.
The currently chemically synthesized Xuanjing is extremely cold. Put it in a place, preferably without ventilation. It will soon freeze around and form a fist-sized ice block.
And here... it is definitely not a synthetic mysterious crystal, the synthetic mysterious crystal does not have such a great effect.
In fact, Li Tian and the others are not sure what it is. After all, they don't understand everything. There are more strange things under the sky, and there may not be a single thing that can cause such an effect.
"Can you see what caused the ice here?"
"This……"
Ghost King's complexion was not very pretty either. Although the cave was cold, it was far from the ice so thick. You know, the ice is so thick that it requires not only temperature, but also a lot of water.
How can there be water in it?
Inexplicably formed such an ice cave? No one can believe it.
"Unless... there is something extraordinary in it."
"what?"
"Some animals, some very weird animals, can freeze some things with their breath."
"What? Isn't that the fairy beast in the legend?"
"No, it's just a bit weird. It is said that two thousand years ago, many such strange animals in the world, but now they have disappeared."
"Because of what?"
"Because at that time, the aura was sufficient and could cause some animal mutations. You see, for example, the dinosaurs that existed before have particularly powerful powers, as well as the legendary Suzaku and the blue dragon. Maybe even if they don’t exist, there must be something similar. Things. Animals are sometimes no worse than people. People can reach the realm of masters through cultivation, so those animals may not be impossible."
The meaning of the words of the King of Ghosts is that thousands of years ago, there were some relatively powerful animals, because of their aura, they have mutated and produced some incredible abilities.
"To tell you the truth, I have seen rats that breathe fire."
Finally, in order to increase the persuasive power, the ghost king said one thing.
As soon as he said this, Li Tian would of course no longer doubt anything. It is definitely not something that can produce ice in this environment. Apart from this explanation, it seems that nothing else can hold up.
What's in it?

This book is not about comprehension. Although it seems to involve a bit, it will definitely not be described. If you want to write about comprehension, I will open another book. This book is in the city until the end of the book, without writing comprehension.
