So, everyone waited quietly for a quarter of an hour, but still did not feel any movement in the mountain.

"Senior Brother Yu, I don't think there should be any danger down there, why don't we go down and have a look?"

It's been so long, if there was something terrible down there, I'm afraid it would have rushed out a long time ago. Since there is no response, there should be no danger.

"Well, you guys step aside first!" Cheng Yu also felt that the time should be almost up, so he took out the amethyst sword and suddenly struck the place where there was a sealing rune.

Rumble!

This time, there was no existence of the seal, and when Cheng Yu bombarded it like this, the entire ground suddenly shook, especially the location where the original runes were located, which collapsed all at once.

Everyone walked cautiously over, only to see a huge deep hole appear in front of them. Everyone stood at the edge of the giant cave and looked down, but it was pitch black below, and nothing was visible at all.

"Do you want to go down?" asked Xinluo.

"Of course we have to go down, how can we hunt for treasure if we don't go down?" Xinhai was not afraid at all, and when he saw that there didn't seem to be any danger below, he was ready to jump straight down.

"Wait a minute, have you forgotten what happened to you at the foot of the mountain?" Cheng Yu saw that the other party was about to make a move again, and hurriedly grabbed the other party.

This guy is really good and forgets the pain, it's dark down here, you can't see anything, just jump down, if there is any danger below, you can't avoid it.

"There shouldn't be any danger here, right?" said Kokomi with an embarrassed smile.

"Don't be afraid of 10,000, just in case, we are not familiar with this place, it is better to be careful. How much more have you forgotten all the difficulties we have encountered along the way, and this place is so strange at the foot of the mountain, how can it be easy on this mountain? Cheng Yu said solemnly.

"Yes, don't forget, we can't fly on this mountain, if you jump like this, if there is a bottomless abyss below, won't you kill yourself?" Xinmei also reminded.

"Ahh

"Then how are we going down now? Do we want to hang down with a rope?" the people also realized a big problem, since they went up the mountain, they couldn't fly here.

And this big hole looks so deep that if they can't fly, they can't go down at all.

"Look at that?" Cheng Yu smiled mysteriously, pointing to the Immortal Demon Tower hanging in the air.

"What do you mean?" everyone was puzzled.

"I found that although we can't fly directly, don't you think it's strange that you can hang in the air when you look at the Immortal Demon Tower?" Cheng Yu said with a smile.

"Huh, really, why is this Immortal Demon Tower able to fly in the air?" everyone asked strangely.

"I don't know the reason for this, but I found that here, the aura and spiritual power consumed by using magic weapons are far greater than in other places. But no matter what, this magic weapon can fly after all, but it can't fly for a long time, because the consumption is too great. Cheng Yu said.

"In this way, we can use the magic weapon to fly down!" At this time, Xinluo finally reacted.

"That's right, we can fly down in Linglong Ding!" Cheng Yu directly took out Linglong Ding, loaded everyone inside, and then directly urged Linglong Ding to fly down into this big hole.

However, because it was so dark inside the big hole, they couldn't see the environment inside at all, which made everyone a little nervous.

What's even more frightening is that as soon as they enter the big hole, the speed at which this exquisite dragon sinks becomes so fast that Cheng Yu can't even control it.

"Senior Brother Yu, we won't have an accident, right?" said Xinhai worriedly.

"There seems to be the same attraction in this cave as it was at the bottom of the lake, and I can't control the sinking speed of Linglong Ding now!" Cheng Yu said helplessly.

"It feels so big in this mountain, I don't know what is down here, it's so mysterious!" Xinhai looked out from the Linglong Ding, and all he saw was pitch black, and he could only feel that this place really looked like a huge bottomless pit.

Bang!

After a while, everyone only felt a sudden and violent shock from Linglong Ding, and then stopped!

"What's going on, did we bump into something?" asked Xinluo nervously.

"It seems that we have reached the bottom!" Cheng Yu took everyone out after speaking, and then put away the Linglong Ding.

"Huh, Senior Brother Yu, didn't you say that there is a strong attraction in this, why can't I feel it?" Xinhai felt it for a moment and said.

"It's strange, Linglong Ding obviously felt out of control just now, and the sinking speed was very fast. Cheng Yu also looked puzzled.

When Linglong Ding entered the big hole just now, he felt a powerful force pulling it down. And he tried to control Linglongding's speed, but he didn't succeed.

But now, standing in this hole, I don't feel this strange force pulling everyone, which is really strange.

"Why don't you try again?" Xin Yao reminded Cheng Yudao.

"Okay, I'll try again!" Cheng Yu nodded.

So, he was about to control Linglong Ding to fly towards the entrance of the cave, but at this time, there was only a small white dot at the entrance of the cave they saw, which showed that the distance they were sinking was not a star and a half.

"Senior Brother Yu, why don't you do it yet?" However, after waiting for a long time, he didn't see Cheng Yu getting the Linglong Ding, so Xinluo urged.

"Something is wrong with the situation, I can't make Linglong Ding fly!" Cheng Yu's face was a little ugly, there was really another mystery in this hole, it didn't seem to be as simple as everyone saw.

"Ah, what does that mean, doesn't that mean we can't go back?" exclaimed.

"It seems that this is the case, we seem to be trapped in this hole!" Cheng Yu tried several times, but still didn't let Linglong Ding fly.

So Cheng Yu took out the Immortal Demon Tower again, but Cheng Yu was disappointed, and the Immortal Demon Tower couldn't fly.

"No, we didn't feel anything wrong with this hole, why did this happen?" The others couldn't believe all this, and took out their magic weapons one after another, but they all failed, and they couldn't fly.

"There may be some things in this cave that we don't understand, so let's check the situation in this cave first. We can't get out from the exit above, maybe there are other exits here!" Cheng Yu had no choice but to settle for the next best thing and choose another way to get out.
