107, come on, get on! _1

Upon seeing this chessboard, Su Yu immediately understood that it must be the defense mechanism of the secret passage.

The little Cat Morning Star on his shoulder also nodded:

"Yeah, this is a trap set up in the passage. The main switch should be inside the manor."

"If the Duke enters the passage from outside, he will notify his subordinates to deactivate the mechanism, and he can pass through unimpeded. But we can't shut down the main switch, so we probably have to force our way through."

"Force our way through?" Su Yu looked worried, "But I don't know how to play chess!"

The chessboard was already here. Obviously, the passage could only be navigated by playing a game of chess.

If it was Chinese chess, Su Yu would be able to make a move or two.

But international chess...

He really didn't know how to play!

...

"It's okay, I'll guide you."

Cat Morning Star jumped off Su Yu's shoulder.
