Chen Danxia took out a secret picture, which read: "Four flat and stable".

When I pushed open the stone door, what appeared in front of me was a stone pillar that was horizontal and vertical, with numbers of one, two, three, and four engraved on the stone pillar.

"How do you want to pass this?" Mr. Duan couldn't remember it at all. He was the one who knew the mechanical skills. He relied entirely on Shangchen Danxia.

Chen Danxia lowered his head and pondered, muttering in his mouth, "Four, eight, thirty, two, the first row has four, but the second row has eight, but three and two."

The four of them stood quietly beside her without disturbing her thinking.

After a while, Chen Danxia seemed to figure it out and said, "You four go and move the four stone piers in the stone chamber."

The four of them did not ask what to do when moving the stone pier, and moved the four stone piers over as they said.

"Put them on the four pillars separately." Chen Danxia directed them.

After the four of them put the stone pier on it, there was no change except the stone pillars engraved with three characters. The other three fell down and were soon swallowed up by the darkness below. The four of them changed slightly and looked at Chen Danxia. Chen Danxia smiled and said, "It seems that my idea is right. Third Master, move the stone pier down."

Xu Lang moved the stone pier down.

Chen Danxia hesitated for a moment and said, "San Master, step on the stone pillar, and then place the stone pier on the second row of stone pillars engraved with two words."

Xu Lang acts according to his words and actions.

The stone pillar where the stone pier is located has not descended.

Chen Danxia asked Xu Lang to move the stone pier back and step on the second row of stone pillars with two words inscribed, "Class Zhao, please follow my third master and hand over the stone pier."

"No trouble, I'm happy to serve." Zhao Chengzhi smiled and also went to Shizhu Road.
