Back in the tomb, Lao Jiu immediately lit a candle.

See the candle flame appear a little bit of pour out, although only a little bit, but still tilted.

Seeing the slanting flame, there is no need for Lao Jiu to explain. Xu Shaotang and mu Tiance have understood his intention.

Both of them shine at the slant of the candle flame at the same time.

This is located in the southeast corner of the tomb. If you raise your hand gently, you can't feel any air flow at all, but the inclination of the candle flame won't deceive people. There must be a vent nearby to let the air flow in the whole tomb.

Lao Jiu picked up the candle and walked slowly in the direction of the southeast corner. Then he put out his hand and stroked the wall in the southeast corner. It was like stroking his lover.

Looking at Lao Jiu's appearance, Xu Shaotang and mu Tiance can't help feeling a chill.

After searching on the wall, Lao Jiu slowly raised his head and focused his eyes on the top of his head.

"The vents are up there!"

Lao Jiu's frown finally slowly stretched out, and his face also showed a slight smile.

Xu Shaotang and mu Tiance look at the position of the strong light on Lao Jiu's head. They see that the arrangement of the stone walls on Lao Jiu's head is slightly loose. Different from the stone walls in other places, they can see that there are small gaps between the stone walls on Lao Jiu's head. Those gaps seem to be less than 5mm. If you don't look carefully, you can't find them.

Although there are only a few small gaps, they provide flowing air for the whole tomb. It's because these gaps are small that they can't feel the flow of air at all.

"I'll see if I can break this stone!" Xu Shaotang motioned Lao Jiu to step back slightly, then jumped up abruptly and punched heavily on the stone above his head.

"Boom..."

When Shaotang's fist was shot at the top of the cave, he could see the power of the stone.

"Sure enough, it's empty!"

Lao Jiu said with a smile: "I didn't expect that the foreigner had a lot of thoughts. If I hadn't thought about it suddenly, I would have been cheated!"

Xu Shaotang said with a smile: "you think this foreigner is a fuel-efficient lamp! Well, don't be so wordy. Go in here and see if you can find the tomb here. "

"I'm sure I can find it!" Lao Jiu said confidently: "as long as there are other tombs here, we must need ventilation. As long as we follow the vent, we can find it!"

"I hope so!"

Xu Shaotang said with a smile, "go ahead and have a look!"

At the end of the speech, Xu Shaotang took the lead to jump up, grabbed the hole, climbed in, and then pulled Lao Jiu up.

The ladder is very narrow. It only allows one person to walk with a cat's waist. The winding ladder is in a spiral shape. They walk up the ladder all the time. After walking for a while, a forked road suddenly appears in front of them. One continues to wind up, while the other is circling in the direction of their right hand.

Xu Shaotang turned back to Lao Jiu and asked, "which way to go?"

Lao Jiu thought a little and said, "go right! If I guess correctly, the upward road should be the exit to the top of the pyramid, and the right road may be connected to other tombs. "

Xu Shaotang thought about it and felt that what Lao Jiu said seemed reasonable, so he went to the channel on the right.

Down the passage, and soon, there was another fork in front of them, one to the left and one to the right.

Looking at the fork road in front of them, after asking Lao Jiu's opinion, they chose to go to the right again.

After another walk, the fork road appeared again.

This time, Xu Shaotang did not ask Lao Jiu's opinion again, but said to himself with some doubts: "something's wrong, this place, we seem to have been here!"

"There's something wrong with it, and I feel like we're in circles." Mu Tiance, who walked behind, frowned slightly.

"Lao Jiu, what do you think?" Xu Shaotang asked Lao Jiu again.

Lao Jiu thought about it and said, "I can't judge it, but I believe you feel it. If you want to be sure, we can make a mark here first. We can choose any road first to see if we will come back here again."

"Good!"

Xu Shaotang nodded, immediately picked up Qi, made a very conspicuous mark on the stone wall, and then casually chose one side to walk.

More than an hour later, they saw the mark Xu Shaotang had made before.

"It seems that we are really in a circle!" Lao Jiu said: "this kind of ladder, we call it the enchantment ladder. What many people call the ghost fighting against the wall, is actually similar to this, while it is called the panlos ladder in foreign countries."

"To be specific!" Xu Shaotang sat on the stairs and asked with great interest.

Lao Jiu also sat down to have a rest, and slowly explained to them: "one of the characteristics of this kind of ladder is to use people's visual error to give people the illusion of going up or down all the time, but it's actually going around in circles! Our current ladder should be more sophisticated and complicated. There are several branches in the ladder, but no matter which one we take, we are actually going in circles. "Hearing Lao Jiu's explanation, mu Tiance frowned and said, "is there any way to crack it?"

"Yes!" Lao Jiu nodded and said: "close your eyes, don't look at the road in front of you, just go with your own feelings! However, this method is not necessarily useful. People who can design such a complex enchanting ladder may have prevented people from using this method when building here. "

"Try it first!"

Xu Shaotang slowly closed his eyes and said: "Lao Jiu, you take the rope to connect the three of us, so as not to be separated."

Lao Jiu nods, takes out the rope in Xu Shaotang's backpack, and quickly ties them together according to Xu Shaotang's requirements.

After finishing everything, Xu Shaotang set out immediately. This time, he did not rely on his own eyes at all. He just walked with his own feelings and left a bottle of mineral water on the ground.

More than an hour later, Xu Shaotang, who was walking in front of him, suddenly stopped. There was a dead end in front of him.

Xu Shaotang slowly opened his eyes and said to Lao Jiu with a wry smile: "it's out of the enchanted ladder, but it's in the dead end again."

"Don't worry, Xu. Let me have a look first!" Lao Jiu also opened his eyes and said slowly: "although it looks like a dead end, it may not be what we imagined. Maybe we will find a way out from here!"

"You mean, there's a hidden mechanism here?" Xu Shaotang asked lightly.

Lao Jiu shook his head slightly and said, "I don't know. I have to watch it first."
