After watching Luo Fatzi and the three of them turn around and walk out of the valley, Wu Ze began to walk towards the depths of this valley.

Standing at the entrance of this valley just now, he could only take a cursory look at the general situation of this valley, and if he wanted to get more details, he had to go inside, get closer and observe.

Wu Ze carefully observed the surrounding situation as he walked inside, and as he went deeper, the first thing that caught his attention was the color of the stone walls on both sides of this valley.

When he stood at the entrance of the valley just now, due to the distance and the fact that he hadn't looked carefully at the time, he didn't pay attention to the anomaly on the stone wall.

Now that he had arrived, Wu Ze found that the color of the stone walls on both sides of this valley was completely different from that of the lower part.

The color of the upper part of the stone wall is blue-gray, which is similar to the color of the rocks in other parts of Lishan, and it looks normal.

What caught Wu Ze's attention was the lower part of these stone walls.

Starting from the ground and going up to about two or three meters high, the color of this rock, and the color of the rocks above, is completely different.

The two- or three-meter-high rock is not the blue-gray rock that is common in this area, but a rock with patches of dark red, or dark red spots.

This kind of stone looks a little strange, and at first glance, these stones look like a pot of unfresh dog blood has been poured on them.

And in this valley, there is a strange thing not only about the color of the stones on these stone walls, but after Wu Ze walked to the bottom of this valley, he found that the gap at the bottom of the valley was not naturally formed, but had traces of artificial carving.

After seeing the situation in front of him, Wu Ze suddenly felt a little ripple in his heart.

Obviously, the reason why this valley has become so cold is not only due to the topography of this valley, but also because there are people who deliberately want to turn this place into a shady place.

From this point of view, this valley is indeed strange.

It's just that Wu Ze walked around this valley, except for the different colors of those stones, and the traces of artificial carving in the gap at the bottom of the valley, he didn't see any other clues from it.

The refining of the seven skulls in his backpack, it was recorded in the ancient book that he must come to this valley to refine, as for why it must be refined in this place, Wu Ze only knew it, but he didn't know why.

Wu Ze, who went around in this valley and didn't find any other clues, could only walk out of the valley in the end.

"Wu Ze, do you have any major discoveries in this valley?" Jiang Yan, who had just set up the tent, hurriedly asked after seeing Wu Ze appear at the entrance of the valley.

They came here this time to dig out the secrets hidden in the seven skulls, and Jiang Yanhe had never touched on those mysterious metaphysics, so she could only throw this question to Wu Ze to answer.

"From the bottom of the valley to the gap, I found traces of human carving, it seems that someone is trying to make this valley more gloomy and cold, so this arrangement was made!" Wu Ze replied.

"Could it be that someone wants to turn this place into a place of extreme yin?" Jiang Yan's heart suddenly froze.

You must know that the so-called extreme yin place is the place where yin qi is highly concentrated, this kind of place, but a special existence in feng shui metaphysics, it is said that this kind of location, can keep the buried corpse from decaying for thousands of years, in reality, it is basically unavoidable.

And now, after this valley has been artificially transformed, it is so cold that even the vegetation basically does not grow, whether it is the so-called extreme yin land, it is really hard to say, but to say that this is a rare yin land, it is not an exaggeration.

It's just that those ancients, why did they transform this valley into a yin land? And those seven skulls have to find a yin place to refine?

These questions are like a mystery, which makes Jiang Yan feel that she can't see the truth of the matter clearly.

This valley is a yin land, and at midnight, it is the most gloomy hour of the day, so Wu Ze's heart came to a conclusion.

It seems that refining these skulls is not a simple matter.

"Maybe, who knows" Wu Ze shrugged his shoulders, indicating that he didn't quite know what was going on.

But since he can't figure it out, there's no need to desperately think about it, Wu Ze simply doesn't think about it.

"Okay, since you have set up the tent, let's go to the tent to rest for a while, and take care of our spirits, so that we can have the energy to solve the problems of the night." Wu Ze waved his hand and went into the tent.

As the old saying goes, sharpening a knife is not wrong for a woodcutter!

If they take good care of their bodies in advance now, then in the middle of the night, if something unexpected happens, they can also deal with it calmly.

An afternoon, in a blink of an eye, passed quickly, and after Wu Ze and the four of them hastily ate some dry food, they sat down next to the tent and began to close their eyes and recuperate.

It's just that before Wu Ze could close his eyes for a long time, he heard Luo Fatzi ask beside him: "Brother Ze, will there really be anything strange happening in this place at night?" ”

After climbing the mountain road all morning, Luo Fatzi felt a little tired, but when he rested for an afternoon, the whole person was suddenly resurrected with blood and blue, which is not his current mental head, but it is much better than at noon.

"It's the first time I've experienced this kind of thing, and I don't know what accidents will happen." Wu Ze spread his hands, indicating that he didn't know much either.

No one has been able to collect seven skulls before, so after these skulls are refined, what will happen to them, there is no explanation in that ancient book, Wu Ze can't figure it out, and that is a very normal thing.

After hearing Wu Ze's explanation, Luo Fatzi could only wait for the arrival of Zishi with some apprehension.

As it approached midnight, the wind was noticeably stronger.

"Hoo ......"

After a very cold night wind blew, a layer of goosebumps immediately appeared on Luo Fatzi's body.

Luo Fatzi, who had already put on all the clothes he was carrying, was suddenly shocked.

Before this is the time, the cold night wind has already begun to be strong for a while, if it is the coldest time of the day, then this wind blows, then it is still necessary?

"Ze...... Brother Ze, it's so cold! Luo Fatzi, who was holding the sapper shovel in his hand, had already begun to shiver after being blown by the cold night wind.
