Chapter 5138:

I saw a clear dividing line a few meters away from his feet.

On the side of the dividing line where he was standing, the hot ground was already a little red, and the hot air was constantly surging upwards.

At the other end of the dividing line, there is thick snow and ice, and large swaths of snow are still falling down on the sky.

Occasionally, a few pieces of snowflakes accidentally cross the border and fall here, before they fall to the ground, they are melted by the heat floating in the air, and directly turn into hot water vapor and float into the air again.

The thick ice and snow at the junction continued to melt with the hot temperature, and continued to freeze again.

Although there is only one line of separation, it seems that there are totally two seasons and two worlds on both sides.

Yun Yi pursed his lips and carefully reached out his hand to reach the other side from the junction.

The cold snowflakes fluttered and fell on his hand, and then turned into a small drop of water in his palm. Other than that, there was no danger or accident.

Yun Yi then raised his leg and walked to the ice and snow world on the other side of the dividing line.

I walked back and forth several times on both sides, except for changes in temperature and climate, there is no other difference.

Looking around, the front is white, and judging from the snow cover on the ground, the deeper you go, the lower the temperature inside, and the thicker the ice.

He had searched all areas of the hunting area outside, and there was no trace of the man and his face at all.

If that person really hid here with his face, he would definitely not continue forward.

Yun Yi thought for a moment, and walked forward along the dividing line.

Sure enough, after a while, a few faint footprints were finally found on the snow that was a little far from the dividing line on the other side.

Because the temperature difference between the two sides of the dividing line is too large, the falling snow next to the dividing line cannot fall on the ground to form snow, and naturally it will not be able to leave footprints.

And the location too far from the dividing line, and because the temperature is too low, after the snow hits the ground, it will be directly frozen into an ice layer shortly after the foot is stepped on, it is impossible to leave footprints.

Only when the distance is not too close, the temperature is just right, and the position that cannot be changed will leave footprints.

The lighter ones have been covered by the falling snow later, and these footprints probably bear the weight of two people, which are much deeper than ordinary footprints, so they can be seen a little faintly.

Yun Yi's face was gloomy, and he quickly walked in the direction of the hole along the dividing line.

There are not many footprints along the way, only one or two can be seen occasionally, but this at least shows that he is looking for a good direction.

On the outside of the hole, there was the last footprint, which seemed to indicate to him that they had entered it on purpose.

Yun Yi is not a person who is empty and powerless, but has no IQ.

On the contrary, his IQ is very high, and everything in front of him is too obvious.

From the disappearance of Yan Yan, to Yuan Yuan looking for him, and then to those looming footprints leading him here.

All of this seems to be a matter of course, but when you think about it, it's more like a game.

Introduce him into the game in this cave step by step.

When he first knew that Rong Yan was missing, he did not expect that he would come here step by step according to the plan of the person who set the game.

But after seeing the footprints appearing behind, he understood in his heart.

After all, it is really not easy to leave footprints here.
