After waiting in place for a while, Yu Fei took a deep breath and cautiously stepped forward again when he saw that the strange sound did not come out again.
Following the traces of water washing, Yu Fei walked all the way. Fortunately, there were no forked caves in this cave. There was no need to worry about taking a side track. However, the deeper he went into the cave, the steeper the terrain became. The original slope of thirty degrees had become fifty or sixty degrees. Moreover, the ground was still very slippery. Yu Fei had to hold on to the cave wall and move forward very carefully to avoid slipping.
In addition, the cave has become wider and wider. Now it has reached a width of more than ten meters. However, the height of the cave roof has decreased. If Yu Fei stood up straight, his hair could even touch the cave roof. It was slightly uncomfortable. Shen would even scratch his scalp, so he could only move forward with his waist hunched over.
He didn't know how long he had walked. Perhaps it was because of the rugged road and the extremely quiet surroundings that Yu Fei couldn't help but have an illusion. He felt as if he had been walking for several hours, but he had not seen the end yet. And Because the cave continues to extend downwards and after walking for so long, it is probably hundreds of meters underground. There is a cold air everywhere. Coupled with the extremely quiet atmosphere, Yu Fei can't help but feel a little frightened.
He stopped and carefully explored the surroundings, but found nothing except the wet rock cave walls. The cave was still bottomless, and he didn't know how much longer he would have to walk inside.
"Damn it, there's no end to this. Could this damn place lead directly to hell?" Yu Fei sighed. He couldn't help but regret. Obviously Shennong would not hide in such an environment. Maybe it really is. It's just a demon god sealed away. Even if the series of strange things that happened in Blackwater Pond recently have something to do with this demon god, since he is sealed in such a deep place, it will be difficult for him to go out and harm the villagers. Why should he worry about it? .
Yu Fei was hesitating whether to turn back or not, but suddenly he seemed to hear something. He hurriedly listened carefully. It turned out to be the sound of splashing water.
He couldn't help but feel startled. He thought to himself: "Why is there the sound of water? It is impossible for such a terrain to hold water. Could it be that it is almost at the end? But what is stirring the water? We have already come here. Why not go and see The truth."
Driven by curiosity, Yu Fei walked forward again.
The terrain is getting steeper and steeper. And because the height inside the cave is too low, you have to bend your body as much as possible even when walking. Naturally, you can't walk with your breath. Therefore, every step forward is very difficult. Yu Fei must be very careful. .so as not to slide down.
He walked forward cautiously like this. After walking for more than a hundred meters, his eyes suddenly opened up. A cold air came towards him. A huge cliff appeared in front of Yu Fei.
This cliff is forty or fifty meters high. Below the cliff is an extremely huge underground lake. The lake is very wide. At a glance, you can't see the edge. It is different from the underground lake that I saw in Lop Nur. In comparison, I'm afraid they are even worse.
Yu Fei is now on a cliff next to the lake. There are no roads leading to the lake. The only way to get down is to fly with air.
However, Yu Fei did not dare to act rashly. Although the lake surface seemed very calm now, after all, he really heard the sound of splashing water just now. And it could be heard from such a long distance, which is enough to show that the splashing water was not I don’t know what it is, so it’s better to be cautious.
He activated his spiritual sense and carefully explored the surrounding situation. However, because it was too wide down here, the detection distance of his spiritual sense was relatively limited. He could only detect a few hundred meters in radius. There was something farther away. He couldn't detect it for a while. And there was no way of knowing what might be hidden under the lake.
Yu Fei was exploring carefully when he suddenly discovered that on the lake about a hundred meters away from where he was currently, there was a small island protruding from the lake. And on that small island, there was a faint mass. The firelight swayed in the cold wind.
Seeing this situation, Yu Fei was suddenly startled. How could there be fire on the island? Could there be someone there?
He calmed down and decided to find out what was going on. So he kicked off his feet, rose into the air, and flew towards the small island.
The distance of more than a hundred meters is not that far. After a while, Yu Fei was already on a circular island with a diameter of only about seven or eight meters. He took a closer look and found that the island was not actually circular. .It is in the shape of an octagon, which is the Bagua pattern.
Obviously, this island is not naturally formed. It is an artificial island.
Yu Fei couldn't help but wonder. Who would build an artificial island in this underground lake? And what is the significance of the existence of this artificial island?
Since it is a Bagua pattern, it means that it contains a yin and yang aura. Maybe it is a mechanism. Yu Fei did not dare to step forward rashly for a while.
He urged his spiritual sense to carefully examine the Bagua Island at his feet. The entire island protruded from the water for about two or three meters. The island was not made of ordinary stone, but made of a material similar to bronze. Of course, although it looks very similar, Yu Fei can basically conclude that this material is not bronze, because if it were bronze, it would have been rusted by being immersed in the lake like this. Yes. But not only is there no trace of rust on the island, it also looks quite smooth.
It can be seen that this is a very special material. Maybe it is not something from the human world, but comes from the god world or the ghost world.
In the center of the island, there stands a square stone pillar about one meter high and one foot square. Above the stone pillar is a lamp niche. In the lamp niche, a faint blue and white fire is quietly glowing. Burning. When the cold wind blows over the lake, the fire will sway left and right.
Yu Fei stared at the lamp niche for a while. He soon discovered that the fire contained extremely rich spiritual energy. It was obviously not an ordinary fire. It was probably an ever-burning lamp using the spiritual energy of heaven and earth as fuel.
After being stunned for a long time, Yu Fei cautiously walked towards the lamp niche because he vaguely felt that there seemed to be some words engraved on the inner wall of the lamp niche. He wanted to get closer to see what happened, but he was a little worried that he would I accidentally touched some mechanism, so I was very cautious. Almost every time I took a small step forward, I would stop and observe. Only after confirming that there was indeed no movement, I dared to take the next step.
