"What are you doing?"
Ou Zheng asked with confusion in his heart.
"Finding the midpoint."
Bai Yanliang said without turning his head.
Just as Xu Zhifei had guessed.
And when Bai Yanliang revealed the significance of his current action, the three finally understood his intention.

Throw a bit to the right, and it's the hand on the left wall reaching out.
Then... what about directly in the center?
At this moment, Bai Yanliang suddenly beckoned, and Xu Zhifei stepped forward to help him hold one end of the shoelace, pulling it completely straight.
Bai Yanliang held the other end, and the two of them measured the width of the corridor with the shoelace in front of them.
Next, Bai Yanliang folded the measured shoelace in half and made a mark at the midpoint.
This time, even the most foolish could understand his strategy.
