It has to be said that there are really many traditional Chinese medicines on Daya mountain. Even many traditional Chinese medicines that Shi Lei has never noticed in his daily life will appear in this place.

If Shi Lei has the opportunity to return to the capital Chinese Medicine Association in the future, this place must be of great help to Shi Lei.

Of course, these are later words. At present, Shi Lei must find out the secrets hidden in Daya mountain, including the place where he made the old man unconscious that day.

Shi Lei was looking for it aimlessly. Suddenly, he saw a row of animal footprints under his feet. It looked like some animals. But Shi Lei seems to have never heard of the existence of this animal on Daya mountain.

Anyway, it's always good to come forward and have a look, so Shi Lei slowly groped along his footprints to a place not far in front of him, and planned to find out what this animal is.

But when Shi Lei came to the end of his footprints, the scene in front of him still surprised him, and he couldn't even believe his eyes.

This is a cave.

In any mountain, the appearance of caves is not particularly rare, especially in some places with a long history, whether it is the power of nature or the caves inhabited by some animals, this geomorphic feature will not be too rare.

However, the cave in front of Shi Lei was beyond his expectation. It was not like something that could be made by nature. Whether it was symmetry or the decoration on it, it was more like human hands.

"Is there any trace of human existence in this deep mountain?"

When Shi Lei had this idea in mind, the whole person suddenly became creepy, and even some couldn't believe what might happen next.

After all, the situation of Daya mountain is special. Although everything is very harmonious at this time, Shi Lei is not aware of any danger.

But once it comes to the rainy season or some bad conditions, Daya mountain will become the most terrible existence.

Those who can stay here for a week are definitely not good people, let alone those who live here for a long time.

Moreover, such a magnificent cave is only located near the hillside for many years and has not been found by anyone. This matter makes Shi Lei even more surprised.

With strong curiosity, Shi Lei walked in slowly.

The entrance to the cave is very large and can accommodate at least four or five adult men passing side by side.

But the more you go to the back, the channel becomes narrower. In the end, it is extremely difficult for Shi Lei's body to shuttle here.

The whole cave looks very dark and humid. Perhaps because of the cave, Shi Lei can always feel a trace of rotten smell.

Struggling with his discomfort, Shi Lei hurried forward, and the flashlight on his head also made Shi Lei adjust to the darkest brightness.

Once any situation is found, Shi Lei will certainly have the opportunity to escape. This is also a long-term experience, which makes Shi Lei have a very careful plan.

At this time, Shi Lei stopped and looked at the patterns on the walls on both sides of the channel. For a time, he was actually lost in meditation.

The light of the flashlight shines on these patterns, which really adds a bit of mystery.

"What the hell are these things?"

At this time, no one can give Shi Lei an accurate answer.
