A thick beam ran across the ceiling, supporting the weight of the floor above. It spanned the entire room, extending all the way to the partition wall.
Zhao Lin moved a table under the beam, climbed onto it, and ran his hand along the beam, pressing it inch by inch.
Near the partition wall, the beam was supported by a pillar, with a section of the beam jutting out just past it.
Zhao Lin pressed on it and immediately felt it give way. He gave it a gentle push from below and heard a soft CLICK.
He straightened up, looking down from his vantage point, and understanding dawned on him in an instant.
The protruding section of the beam was fitted into the main beam using a mortise and tenon joint.
To put it simply, it was like two clasped hands with interlaced fingers, resting on the pillar in a T-shape.
