Hidden Mountain, a tomb within a tomb.

The teacher walked ahead, with the mute elder half a step behind.

It wasn't pitch-dark in the tomb, for there were several luminous pearls embedded in the walls, casting a faint glow.

Also, the lamp full of fireflies in the mute elder's hand added an extra touch of brightness.

The passage was not very long and slightly narrow. After a short walk, they reached a wider area. It reminded them of a passage from the "Tales of Peach Blossom Spring", "The passage was very narrow just enough for one person to pass, and after a few dozens of steps, it suddenly opened up to a wide and bright area."

The wide area looked somewhat like a circular altar, but it was not. There was only a large formation array.

This altar-like round base was connected to forty-nine chains, each leading to the stone walls around, linked with them.

The stone walls were smooth and polished, covered in dense black characters.
