readx; After waiting in place for a while, seeing that the strange sound did not come out again, Yu Fei took a deep breath and cautiously took another step forward.

Following the traces of the flowing water, Yu Fei walked all the way, fortunately there was no fork in this cave, but there was no need to worry about going to the fork, but the more you went to the depths of the cave, the steeper the terrain appeared, the original 30 degree angle of the slope has become fifty or sixty degrees, and the ground is still very slippery, Yu Fei has to hold on to the cave wall very carefully to avoid slipping,

In addition, the cave has become wider and wider, and now it has reached a width of more than ten meters, but the height of the top of the cave has decreased, if Yu Fei stands up straight, his hair can even touch the top of the cave, and if he is not careful, he will even rub his scalp, so he can only hunch his waist and move forward.

I don't know how long he walked, maybe it was because of the rugged road, coupled with the incomparable quietness around him, Yu Fei couldn't help but have an illusion in his heart, he felt that he seemed to have walked for several hours, but he didn't see the end yet, and because the cave has been extending down, after walking for so long, I am afraid that he has gone hundreds of meters underground, and there is a cold atmosphere everywhere around, coupled with the extremely quiet atmosphere, Yu Fei can't help but feel a little hairy in his heart,

He stopped and looked around, but he didn't find anything other than the wet rock walls, the cave was still bottomless, and he didn't know how long he would have to go inside.

"Damn, this is not over, this place must be a direct road to hell. Pen ~ Fun ~ Pavilion www.biquge.info" Yu Fei sighed, he couldn't help but regret a little in his heart, obviously Shennong would not hide in such an environment, maybe it was really just a demon god, even if a series of strange things that happened in Heishuitan recently were not unrelated to this demon god, but since he was sealed in such a deep depth, it must be difficult to go out and harm the villagers, why should he bother with this heart,

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 water splashing,

He couldn't help but be stunned, and said secretly: "How can there be the sound of water, it is impossible for such a terrain to hold water, isn't it coming to an end, but what is the splash of water, it has come here, why not go and see what it is." ”

Driven by curiosity, Yu Fei took another step forward and walked forward,

The terrain is getting steeper and steeper, and because the height of the cave is too low, even walking has to be hunched as much as possible, and naturally it is impossible to resist the qi, so every step forward, it seems very difficult, Yu Fei must be very careful so as not to slide down,

He walked forward cautiously like this, and walked more than a hundred meters, when suddenly there was a sudden brightness in front of him, and a cold air came straight in, and a huge cliff appeared in front of Yu Fei,

This cliff is forty or fifty meters high, and at the bottom of the cliff is an incomparably huge underground lake, the lake surface is very wide, and at a glance, you can't even see the edge, compared with the underground yin lake that I saw in Lop Nur at the beginning, I am afraid that it is more than that.

Yu Fei is now on a cliff next to the lake, there is no road around to the lake, if you want to go down, you can only fly with the air.

However, Yu Fei didn't dare to act rashly, although the current lake surface seemed very calm, but after all, he really heard the sound of a splash just now, and it could be heard from such a distance, which was enough to show that the splash was not small, and I didn't know what it was, so it was better to be cautious,

He urged his spiritual sense to carefully probe the surrounding situation, but because it was too wide below, the exploration distance of his spiritual sense was relatively limited, he could only detect a distance of hundreds of meters, and he couldn't detect anything further away, and he couldn't find it for a while, and as for what would be hidden under the lake, it was impossible to know.

Yu Fei was carefully probing, and suddenly found that there was a small island protruding from the lake about a hundred meters away from his current position, and on that small island, there was a faint fire swaying in the cold wind.

Seeing this situation, Yu Fei was stunned, how could there be fire on the island, could it be someone,

He made up his mind and decided to find out, so he kicked his feet, rose into the air, and flew towards the island.

The distance of more than 100 meters is not too far, and after a while, Yu Fei was already on a circular island with a diameter of only about seven or eight meters.

Obviously, this island is not a natural occurrence, but an artificial island.

Yu Fei couldn't help but wonder, who would build an artificial island in this underground lake, and what is the meaning of the existence of this artificial island?

Since it is a gossip pattern, it means that there is a yin and yang aura inside, maybe it is an organ, Yu Fei didn't dare to rush forward for a while,

He urged his spiritual sense to carefully investigate the gossip island under his feet, the whole island protrudes about two or three meters from the water, the island is not made of ordinary stone, but a metal similar to bronze, of course, although it looks very similar, but Yu Fei can basically conclude that this material is not bronze, because if it is bronze, immersed in the lake like this, it should have been rusted for a long time, but not only does the island not see a trace of rust, but it also looks quite smooth,

It can be seen that this is a very special material, maybe it is not from the human world, but from the god world or the ghost world.

In the center of the island, there is a square stone pillar about one meter high and one foot square, above the stone pillar, is a lamp niche, in the light niche, a blue and white faint fire is burning quietly, when the wind blows on the lake, the fire will also follow the left and right swaying,

Yu Fei stared at the lantern niche for a while, and soon found that the firelight contained an extremely abundant aura, which was obviously not an extraordinary fire, and it was probably an everlasting lamp fueled by the aura of heaven and earth.

After being stunned for a long time, Yu Fei cautiously walked towards the lantern niche, because he vaguely felt that there seemed to be some words engraved on the inner wall of the lantern niche, and he wanted to get closer to see what was going on, but he was a little worried that he would inadvertently touch some mechanism, so he was very cautious, almost every time he took a small step forward, he would pause and observe, and only after confirming that there was indeed no movement, did he dare to take the next step,
