Due to the obstruction of his body, the light in the cave was very dim, but Yang Yao could still vaguely see the objects in front of him. It made him feel a little strange.

After a moment of closer inspection, Yang Yao noticed that there seemed to be other objects glowing inside the cave, and this light took on a dark red color and was emitted by the surrounding walls.

This means that the surrounding walls are capable of emitting red light.

"What's going on?" Yang Yao said to himself, and suddenly he thought that in a book of herbal medicine, there was a material called "fire red stone".

This material is red all over, can emit light, and has a warming effect on the body. It can also be used for lighting.

The walls around here can glow, could it be that there is rutile stone in the walls?

If there is a fire red stone, if it is mined, it should be able to sell a lot of spirit stones. It's just that he hasn't mined spiritual ore before, so he doesn't know which merchant bought it. And for the spirit ore itself, he can't directly refine the fiery red stone, nor can he directly refine the elixir.

Relying on himself, it is still not difficult to refine ore, and now he can only prepare some ordinary potions and medicine powders. For the spirit mine, there is some sighing with admiration.

Despite this, this discovery still made Yang Yao a little excited, and if he could find a buyer for the acquisition after he went out, he would be able to make a lot of money by coming here to mine the rutile stone.

He didn't plan to tell Zhang Zhimeng about this discovery, not because he wanted to keep it alone, but for the sake of insurance, so as not to leak the news. When it's time to mine, it's not too late to call them to make a fortune.

Yang Yao continued to climb dozens of meters towards the cave, and sure enough, he saw some small purple spirit grass in front of him. It's just that the light in front of it has become very dim, and at the end of the field of vision, you can vaguely see some strange-shaped objects, which seem to be the end of the cave, and it seems to be a kind of demon beast.

It's easy to understand that there are monsters inhabiting this cave. After all, this cave is so hidden, suitable for demon beasts to inhabit, and it is accompanied by two spiritual materials, fire red stone and small purple spirit grass, which is just right as a habitat for demon beasts.

If it is a demon beast, fighting in this small cave, the terrain is very unfavorable.

Yang Yao stared carefully at the strange object at the end of his field of vision for a while, but didn't notice any movement from the other party.

I don't think it's a monster. He continued to crawl forward cautiously, and gradually, he came to the little purple spirit grass.

There are more than ten small purple spirit grasses, and the color is a little yellow due to the lack of sunlight for a long time. However, they are all ripe, and they exude a burst of medicinal fragrance.

Yang Yao put away the little purple spirit grass, stopped, raised his head and continued to look ahead, thinking about whether to continue to climb forward.

Zhang Yue'e whispered: "Brother Yao, why don't you leave?" ”

Yang Yao asked, "How deep was the last time you entered this cave, why didn't you take away these little purple spirit grasses?" ”

Zhang Yue'e said: "I haven't climbed to the side of the little purple spirit grass yet, I just look at it from a distance." It's too scary inside. ”

Yang Yao said: "You don't know what's inside the cave?" ”

Zhang Yue'e said: "I don't know, do you want to look inside?" ”

What exactly is the end of the cave? Whether it is a demon beast or an adventure, it is unknown. Yang Yao hesitated for a moment and said, "Let's go and see." ”

Zhang Zhimeng said: "Of course go, Brother Yao, there are generally demon beasts in this kind of cave." If you do, it's a good income. ”

Yang Yao said: "It may also be our burial place, we have to be careful." Although this is the periphery of the Chifeng Mountain Range, there is no guarantee that there are no high-level demon beasts. ”

Zhang Zhimeng said: "It's definitely not a high-level demon beast. Even in the late stage of the first level, we have the strength to fight. ”

Yang Yao said: "Don't be careless. This terrain is very unfavorable for us. We need to be ready to flee first. ”

Zhang Yue'e said: "Xiaomeng, don't be too proud, be careful to make the 10,000-year-old ship." People can also drown in small puddles. ”

Zhang Zhimeng was still unconvinced, but did not speak again.

Yang Yao continued to crawl forward cautiously, the medicinal fragrance inside was getting stronger and stronger, and it was still the smell of small purple spirit grass.

This shows that there are still a lot of small purple spirit grasses in the cave.

However, Yang Yao didn't see where.

In his field of vision, all he could see was a black object like a hill at the end. The object was motionless, and he couldn't tell what it was.

Yang Yao crawled forward for a while, getting closer and closer to the black strange object, and gradually saw clearly. It turned out that this object was a huge stone. And the volume of the stone is even larger than that of a cave.

Seeing this, Yang Yao expected that there must be a cave in the cave, and it was definitely not just able to crawl.

After crawling forward for about a hundred meters, Yang Yao came to the stone and found that there were roads to walk on both sides of the place, and behind the stone was a large space.

It is hundreds of square meters in size, and in the middle of this space, a strange statue has been erected.

It is a statue of a snake.

There was a man who was more than tall, and his body was very thick, about the same as a person's waistline. The two eyeballs are the size of a fist and are black overall. The body is covered with black scale armor.

How can there be a statue here? Or a serpentine statue! Could it be that this is a monk's stronghold?

Upon discovering this, Yang Yao immediately observed his surroundings and found that there were no traces of human monks living around except for the statues.

This means that there are no monks living here for a long time.

So how did this statue end up here?

Does this statue have any special significance?

The surrounding walls still emitted a soft red light, indicating that there must be a large amount of red stone inside the mountain, and there were many places on the walls, corners, and even above the head where small purple spirit grass grew.

Many of these small purple spirit grasses have matured, and their value is to say that there are thousands of spirit stones.

But Yang Yao's attention at this time was completely attracted by the serpentine statue.

The statue's eyes made him feel a little uneasy. But when I looked closely, I didn't find anything out of the ordinary.

Yang Yao came to the statue and found that there was some dust on the scale armor. After carefully looking at the eyeballs for a while, there was really nothing abnormal.

It's just a dead thing, a statue, nothing special.

It seems that a long time ago, I don't know who carved this serpentine statue in this cave. Then the man was gone. As for the reason for the carving of this statue, no one knows.

Yang Yao didn't want to be able to solve the mystery of the statue, but seeing that it was not threatening, he let go of the statue, and turned his head to look at the wall, the surrounding walls could emit a soft red light, indicating that the amount of fiery red stone inside was huge.

This is definitely a great asset. It's just that he can't turn it into a spirit stone now.

At present, what can be done is to collect the surrounding small purple spirit grass and sell it, which can be regarded as a good income.

"Brother Yao, this statue is so weird. I don't know who sculpted it. Why was a serpentine statue carved? Aren't they all carved statues of Pangu? Zhang Yue'e was still standing next to the statue and put her hand on the statue's body.
