But when he walked forward about twenty or thirty meters, he began to realize that something was wrong.

His abilities actually began to fail.

Moreover, the pipe ahead began to bend, and after walking a few steps, I saw a new pipe fork.

"I knew then that I had entered a very complex underground maze, so I planned to return to the first fork and take a long-term view." Qin Fu said, "But..."

"...You can't find the way back?" Xu Xin guessed.

"...That's right." Qin Fu nodded tiredly. "I clearly only walked to one fork in the road, and I clearly remember it was the middle one. But on the way back, I got lost."

His abilities completely failed in the pipeline, and what was even worse was that the watch could no longer communicate with the outside world.

At that time, he was completely trapped in the underground pipe maze.

Fortunately, there is no danger in the maze, unlike the previous dungeon maze, which had mutant creatures and people would fall if they stepped on empty space.

It's just an ordinary stone pipe that can make people get lost in a crazy way.

"Stone pipe?" Xu Xin suddenly asked.

"Huh? Didn't I just tell you?" Qin Fu was stunned. "It's just a stone pipe, but it's very smooth, like polished marble."

Stone pipes.

The floor of the altar, the altar table, and the surrounding stone pillars are all made of stone.

Could it be the same material?

The pipes and the altar are made of the same material...

By the way, when he was offering the sacrifice, those blood-red patterns should have crawled along the stone to the sacrificial table, right?

"It's too complicated in there, and those stones can't leave any marks at all, so we can't carve any words on them." Qin Fu said helplessly.

"It won't leave any traces?" Zeng Tao asked, grasping the key point. "You can't carve it?"

"I can carve it." Qin Fu shook his head and said, "The stone is only as hard as blue-grade stone. I can still carve it, but..."

"The carved marks will be restored." Xu Xin said.

"That's right." Qin Fu nodded. "I only realized this after making many detours. I always carve words at the forks in the road, but after walking for a long time, I never encountered any carvings I had seen before. Later, after carving in the same place and waiting for a while, I found that the carving marks would automatically repair themselves in about three minutes."

"The stone can repair itself!" Zeng Tao was a little surprised, and then said to himself, "If it's used as a weapon, wouldn't it be easily damaged..."

Xu Xin was not surprised.

The ground of the altar will repair itself automatically. This is something he knew when he fought the blood-marked rabbit.

It seems that the material of the underground pipes is indeed the same as that of the altar on the ground.

"Anyway, I walked inside for at least ten hours. Finally, probably by luck, I reached a place that wasn't a pipe: an underground stone room."

Qin Fu looked at Xu Xin and said, "The dagger I gave you is stuck in the middle of that room."

This is how the bronze dagger was discovered?

"The introduction of the dagger really shocked me, but I didn't think much about it at the time. Because when I took out the dagger, the surroundings began to shake, and then the stone wall began to shatter."

And at that moment, his perception ability that seemed to have been blocked was restored.

In his perception, the altar on the ground was collapsing!

And now, he is at the lower edge of the altar!

Fortunately, the stone room had another exit. With his perception, he knew that this was the way back to the ground, so he ran along this passage as fast as he could!

This time I ran at least a thousand meters.

When he came out, he was already at the edge of the hilly resource area.

He looked towards the altar, only to find that it was no longer visible.

Completely collapsed.

Hearing this, Xu Xin narrowed his eyes slightly.

The altar...really collapsed?

He remembered that he had found a passage under the altar table on a moonless night, but the passage was very short and blocked.

Didn’t Qin Fu explore there?

"And then? How come you haven't gotten to the point after talking for so long?" Zeng Tao urged, "Where's the troll? Why hasn't the troll appeared yet?"

"...After I returned to the ground, the troll appeared." Qin Fu's eyes flickered for the first time, as if he still had some lingering memories of the scene. "That troll was actually transformed from a hill!"

Hearing this, Xu Xin's eyelids twitched.

Qin Fu looked at Xu Xin again and said with a wry smile, "Boss, let me tell you, the location of your tree house is incredibly dangerous. There are monsters all around here."
