This time, no one knew the destination of Shi Lei's trip except his neighbor uncle Huang and his assistant.

After all, it's not a big deal. If everyone in the village knows, they will all be concerned about Shi Lei's safety at that time, which will add more trouble to everyone.

Shi Lei is not a person who likes to trouble others after all, so it's better for fewer people to know about this trip.

Uncle Huang urged him to make it clear which places in Daya mountain were more dangerous. He also told Shi Lei not to walk at night. Any action must be carried out in the light.

Shi Lei also had a simple understanding of these situations, so he understood what uncle Huang meant. He gave him a hug and said half jokingly before leaving.

"Look, I'll bring you some fun this time!"

Uncle Huang is very worried.

If Shi Lei hadn't insisted on going to the mountain to see the situation, uncle Huang would have kept him at home.

But this time, the situation was special. It was not Shi Lei's impulse, but because he received a patient in the village after work that day. The patient's words made him more curious about the mountain.

Although many people in the village live a good life today, there are always some old people who still remember their abilities in those years, so they want to go to the mountains and forests to find some rare things to sell for money, which is a lot of economic income.

But when he entered the deep mountains, he found something wrong with the weather and climate at the beginning, but he didn't take it to heart.

But then, without his knowledge, the old man suddenly felt paralyzed and completely unable to move. Then he vaguely saw several dark shadows around him.

When he woke up, his body was full of blood, but all organs were normal. When he went back, he checked with Shi Lei. Even Shi Lei didn't find anything wrong with his body.

That's the weirdest thing.

Of course, Shi Lei didn't tell anyone about this situation, but told the elderly not to spread it.

In this situation, once there is any disturbance, it may be over interpreted by everyone. Shi Lei still hopes to find out the truth in advance, so that he can have more confidence to explain this matter when everyone asks for details.

This is the real purpose of Shi Lei's trip.

When the car took him to the foot of Daya mountain, the fresh air around him was really refreshing. For a time, Shi Lei actually forgot what he should do next. Instead, he greedily opened his hands and breathed the long lost fresh air.

It was only the sounds of unknown animals around him that immediately brought Shi Lei to reality. He remembered something, so he immediately reorganized his equipment and planned to start from the west to see what was here.

The old man was injured and didn't go to a higher place. According to what he said, he only reached the halfway up the mountain.

Shi Lei walked to a mountain path for the first time. This is the road that many herb collectors used to walk out. But time has changed. No one has walked on this road for many years, and many weeds have grown on it.

The surrounding lush trees do seem to block out the sun. Even now, when the sun is shining, you can only see a little shadow.

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.
