Qi Xiaobao and Chu Xixuan followed Lan Ziye into the passage. The passage became darker and darker, and there was no light at all inside. Fortunately, there was a small light bulb on the safety helmet, and Qi Xiaobao was holding a flashlight behind them, so they could barely see the entire passage clearly.

There was nothing in the tunnel. The walls and ceiling of the tunnel were made of mud and small stones, and the ground was also all mud. It looked like an ordinary underground tunnel dug by ordinary people. There was nothing unusual about it, and it was very rough.

"This Wanjia doesn't look very good!" Qi Xiaobao said disdainfully as he surveyed the tunnel. "Even if it's a fake tunnel to hide the truth, they should have used some kind of reinforced concrete or something. With this loose soil, isn't he afraid the tunnel will collapse?"

Lan Ziye, who had been using his spiritual sense to check, always felt something was wrong but couldn't put his finger on what, when his eyes suddenly lit up. He turned to look at Qi Xiaobao who was following behind him and said seriously, "What did you just say?"

Qi Xiaobao was startled by Lan Ziye's sudden words, and his head shrank involuntarily. He looked at Lan Ziye pitifully like a little lamb and asked cautiously, "I... didn't say anything?"

Mr. Chu's wife is so scary, he has to keep his distance! (???????)

Lan Ziye rubbed his chin, pondered for a moment, and suddenly said to himself: "Right, this isn't three thousand years ago, this is the age of reinforced concrete, but this is a completely earthen passage..."

Qi Xiaobao finally understood why Lan Ziye suddenly asked him this. He felt a little proud, but then he spoke cautiously, "Yes, if it were our Qi Family Castle, we would never build such a shameful passage!"

"This soil is very loose, very moist, and... abnormally black?" Lan Ziye squatted down, grabbed a handful of soil and observed it carefully.

"What's so dark?" Qi Xiaobao grabbed a handful of soil and took a look at it with a puzzled look. There was nothing unusual.

Lan Ziye's brows suddenly tightened. He turned around and said with a vigilant look: "This is a landslide formation!" Then he took out a handful of copper coins and threw them out. The copper coins fell to the ground with a loud bang.

Lan Ziye shouted, "Stand on the copper coins!"

"The copper coin is so small, how can it stand?" Qi Xiaobao said with an exaggerated expression.

"If you don't have the ability to stand, then wait to be buried alive!" Lan Ziye grabbed the air, held the Falling Star Halberd in his hand, and flew up to stand on the copper coin.

At the same time, Chu Xixuan also flew and stood on a copper coin not far from Lan Ziye.

The moment Lan Ziye's feet touched the ground, the ground around him began to sink, and the dirt and stones on the ceiling and walls also fell down, as if they were going to be buried alive in the passage.

"Oh! My God!" Qi Xiaobao screamed. Before he could react, the back of his collar had been hooked by Lan Ziye's Falling Star Halberd. He was hanging high in the air. Under his feet was rolling and boiling soil, like magma, and an endless abyss!

Qi Xiaobao swallowed his saliva, looked at Lan Ziye in horror and said, "This really doesn't seem to be a mechanism!"

How could a mechanism produce such a strange effect?

Lan Ziye raised a disdainful smile at the corner of his mouth, swung the Falling Star Halberd violently, and Qi Xiaobao landed steadily on a copper coin.

Qi Xiaobao looked down cautiously. There was only a foot-sized foothold where the copper coins were scattered. The rest of the place was an abyss of rolling mud. The mud was like the mouth of a devil, roaring and screaming, as if it wanted to swallow up everything that fell on it.
