Everywhere that can be seen on the stairs is covered with black soil and limestone. I don’t know how much there is, and it has submerged the stairs above. The stone and soil have fallen from above. It seems that the top of the building should be empty.

The floor of the cavity.

But since the stairs can lead here, it proves that there must be a passage or room above. Bai Chi looked down and saw a ball of rolling light yellow poisonous gas that had spread to the next floor. Bai Chi pushed Bai Ping.

He shouted: "The poisonous gas is coming up! Climb up quickly!"

The soil that had just collapsed was very soft, making it slippery as you climbed. After climbing four or five meters, you couldn't even find any trace of the stairs. The secret passage in Baichi was broken. The passage connecting the stairs or the entrance to the room must have been buried in the collapsed soil.

If the upper soil layer is very deep and the hole is not blown, it will be over.

At this time, Liu Wei and Cheng Hao were also silent. The four of them used their hands and feet to climb another four to five meters. Bai Ping in front of them immediately shouted: "There is a door!"

Bai Chi didn't even have time to look, so he said: "What nonsense are you talking about? Climb quickly!"

After he finished scolding, Bai Chi smelled the faint spicy smell, and quickly held his breath to speed up.

There was a huge rock leaning on the mound. After Baichi climbed up, he saw a faint light coming from above. The boulder was three or four meters vertically above the ground.

At this time, Bai Ping, who was stepping on the boulder, stretched out his hand to pull Bai Chi up, pushed him to the wall, and shouted: "Chief, grab the rope and get up quickly!"

The rope should have been left by the previous person. This is not the time to be pretentious. If Bai Chi is polite again, the dead man will definitely be dead.

It only took Bai Chi a few seconds to climb to the ground. He didn't even have time to look around, so he stretched out his hand to pull Bai Ping and said: "Hurry up!!"

Bai Ping didn't speak. He probably choked on the poisonous gas. He coughed hard, grabbed Bai Chi's hand, and pulled him up. Then came Cheng Hao and Liu Wei.
