"Wasn't it like this when you came before?" Zhang Ze asked.
"Back then, there was another iron plate here. I would put the Iron Hand on it, and Dan Dan would open the door for me," Wei Dalu said.
Zhang Ze and Chen Qin went over, following Wei Dalu and his daughter to study this new contraption together.
Under the ice, there lay a metal plate, inscribed with elegant writing, and beneath the text was an array resembling a labyrinth.
In the array, there's a small metal ball that can be moved using spiritual energy. Once moved to a specific position, it can illuminate a node, releasing the second ball, which interacts with each other, requiring the correct sequence of movement.
Following this sequence, once the whole array is lit, the entrance might be unlocked.
In short, the entrance to Dan Dan's place has shifted from swipe card access to a code lock.
