The remnants of the pine led them away from the magical tree, and the prince guided them straight to the end of the underground world. None of them had the heart to look at the scenery any longer, because the prince told them that in another two thousand kilometers they would reach the end of the underground world, where there was a land of ice and snow created by humans with high technology, and the air was very fresh. Their hearts had long since flown to that strange place.

They drove the birds and soon arrived, the temperature here dropped so much that people were white air, and countless refrigerators on it floated in the vast air, like stars covering the entire starry sky, extremely spectacular, it was exciting to watch, and they had to sigh at the development of human science and technology in the underground world.

Qi Qingshan explained: Strictly speaking, this is not the end of the underground world, but the end of the human underground world, on the other side of the ice and snow, there is also a super powerful animal world, because those ferocious and powerful animals have been living in the extremely high temperature underground world, they are only adapted to the high temperature to survive, so they can not pass through this artificial ice and snow, so in the underground world there is a human world and an animal world.

Kong Tian Si asked: We humans can pass through this self-made glacier and enter the animal world, right?

Qi Qingshan Tancheng said: It is simply impossible, the supreme commander of our underground world has brought countless divine masters into the animal world, and only two or three people can return with their whole body, and our supreme commander is also disfigured, so he has been accompanied by a lion mask all his life. Listening to the older generation, all the animals in the animal world have been mutated, and the reason for the mutation is that human beings have been conducting underground nuclear tests millions of years ago, and those animals have undergone strong mutations because they have been contaminated by nuclear weapons.

Qi Qingshan sighed and continued: "Listening to the old people, the human beings who have just entered the underground world, whether they are children or Confucian women, countless people have been killed and devoured by these powerful mutant animals. Because they have all mutated, they don't listen to human consciousness at all, let alone control these mutated animals. Who do you think we can blame? All of them were caused by previous nuclear tests. Fortunately, due to the high temperature underground, humans must bring refrigerators into it, and those ferocious and powerful animals ran away as soon as they encountered the low temperature of the refrigerator, so people made countless advanced refrigerators, drove all the mutated animals aside, and then arranged countless refrigerators in the sky, forming this continuous glacier and snow land for thousands of kilometers, so that those mutated animals that do not listen to human control are separated from humans.

Ouyang Shiwu said confidently: We will go and kill those monsters now and avenge the dead.

Princess Qi Lushui sneered: Listen to my father, those animals have been mutated, where a small snake is a giant dragon, and a giant python is a mountain, Brother Shiwu, even if you have the divine sense cultivation to move mountains and seas, you may not be able to defeat them. Unless those two demons who are in retreat and cultivation get out, we humans will never want to enter the underground animal world.

The genius boy looked at the remnant pine and said: Master, I like this ice and snow the most, let's play here for a while!

Remnant Song looked directly at the cute genius boy and smiled: Okay, let's not enter the animal world, let's just play in this glacier and snow.......
