After Wang Da finished speaking.
Baiyu didn't stop, either. He walked up to the large door, searched for an angle, and punched the door's pillar twice, causing a stone button to pop out from the pillar.
After Baiyu pressed the button.
The light screen of the door gradually disappeared.
Wang Da seemed a bit uncomfortable: "That's it? So simple?"
Baiyu shrugged: "It's that simple. Didn't the bookshelf clearly state how to open the door?"
Hearing Baiyu's words.
Wang Da leaned in for a closer look and found a small line of text carved under the bookshelf: "Knock on the door pillar to deactivate the mechanism."
However.
This line of text was very faint and could easily be overlooked if not paying attention.
Moreover, if the books on top were not removed.
This line of text would be completely invisible.
