Lin Wu couldn't be bothered with Lu Guichi and went straight back to the study.
Upon entering, Lin Wu first approached the bookshelf, her gaze searching its surface before finally focusing on a book in the fifth row on the left, which she shifted slightly.
With a click, the entire bookshelf began to move, splitting down the middle into two halves and slowly sliding to either side, revealing a hidden door wide enough for one person to pass through.
Lin Wu pressed her hand against the adjacent electronic screen, and the system was instantly activated. A faint blue light scanned her entire body, finally lingering on her pupils.
"Beep—," a cold electronic sound echoed.
[Pupil verification successful, welcome back, Master.]
The hidden door slowly opened, revealing a secret passage.
Lin Wu walked in, and at the end was a vast room.
