Chu Han and Yu Yan walked out of the cave and found that the ice and snow in the ancient Kunlun Mountain had melted more than half, and they could even see the green grass and the big trees that had grown.

In Yuyan's theory, it is likely to be a phenomenon caused by global warming, and experts have predicted that global temperatures will warm and glaciers will melt, and now it seems that this is indeed the case.

But according to this situation, they don't know how long they have been frozen in this cave.

The two of them walked down the mountain along the ancient Kunlun Mountain, and everything in the world here changed dramatically, there were trees everywhere, and all the mountains under the mountain became forests.

The world now has plenty of oxygen and clean air. But along the way, some of the villages and cities they encountered were abandoned or destroyed.

Many cities do not appear to have been ravaged by the war, but the tall buildings are covered with vines, but they are uninhabited. The streets are overgrown with trees, and it looks like they should have been abandoned for many years.

Many animals run and chase along the abandoned roads, as if they have entered a primitive society.

At night, the two set up a bonfire in an abandoned city and grabbed some game for barbecue.

Yu Yan has accompanied Chu Han all the way in the past few days, which is exactly what she wants. Now there are no worldly troubles, no pursuit of fame and fortune in the hearts of the people, no intrigue and deceit, only the beloved by your side.

She grew up in the mountains and forests, so she didn't feel bored with this kind of life, but was full of joy.

In the sweet laughter of the two, Chu Han's skills had improved a lot, and his ears could hear movements within a range of miles.

At this time, he felt a few footsteps hurrying towards this side, and he didn't know what they were. But it should be human beings who go up from the footsteps, but they don't know if they are friends or foes.

In the past few days, they have also found a problem. I saw a lot of animals, different from ordinary animals, all of them seemed to have mutated, but they hadn't reached the level of demon beasts, just animals in mutation.

Chu Han's voice flashed, "There is movement." ”

Then he quickly hid in the abandoned house with the feather goose, and saw a group of people dressed in black running from all sides of the street and gathering at the campfire.

All of them were dressed in black, and by looking at the outfits, they knew that they were not good people, and one of them said, "Where have you gone? There is a campfire here, and freshly cooked food, and we should not go far, so we will look for it." ”

"Brother Chu Han, who are these people?" Yu Yan looked at the clothes of these people, and it seemed that they looked like killers.

"I don't know, the world has become like this now, we don't even know how many years have passed. Chu Han was also confused, and now he only hoped to find a town where people gathered to ask about the situation.

After a while, Yu Yan saw that these people had already walked away and were about to go out, when they were stopped by Chu Han, "Wait a minute." ”

Sure enough, as Chu Han expected, those people came back again after a while. "It's strange that we still haven't found it! Are these wanderers still going to make it to the ground? Let's go meet up with the boss first. Then the men in black dispersed.

Chu Han's voice of heavenly argument, hearing that their footsteps had indeed really gone away, he was relieved to pull Yu Yan out.

The two of them didn't understand what the black people were talking about as wanderers.

Early the next morning, the two continued on their way, and they followed the route of their memories and decided to go to Kyoto.

But now the world is full of trees, like a huge primeval forest. The road has long been abandoned and the buildings are badly damaged. Many villages and towns are also abandoned, uninhabited at all, and some are just wild beasts.

Although the world has become deserted now, the air is much fresher, there is no haze weather before, there is no heavily polluted weather, the whole world is full of birds and flowers, and even the water has become crystal clear, sweet and delicious, and any river can drink it at will.

Unlike the previous world, whether it is rivers or lakes, they are very turbid.

Chu Han had already heard it when he was drinking water, and there were footsteps nearby hurrying towards this side.

He gestured to Yu Yan, and Yu Yan immediately understood what Chu Han meant, and the two continued to draw water quietly, until five people suddenly jumped out of the woods.

Each of the five men had two guns pinned to their waists, long knives or swords behind their backs, and machine guns in their hands.

shouted at Chu Han and Yu Yan, "You two turn around. ”

Chu Han and Yu Yan ignored them and continued to talk about the two of them.

The five of them looked at each other, which was strange! Ordinary people had already been frightened when they saw their battle. Did you encounter hard stubble today, whether they are hard stubble or not, they are only two people.

One of them continued to shout with a gun, "Hey, talk to you two, I told you to turn around, do you hear?"

Chu Han smiled, got up and faced a few people, "What did you just say?"

When the man heard Chu Han say this, he immediately became angry, "I think you are looking for death." ”

Then he took a machine gun and fired several shots into the ground. But it only hit Chu Han's feet and didn't hurt him.

Chu Han's face did not change, he did not move, and he still remained calm.

Seeing the calm and calm appearance of the two, the well-equipped few people were stunned.
