As a time-space stowaway, Anning can always covertly enjoy some privileges, no matter which time and space she's in.
Of course, under normal circumstances, she doesn't need them.
However, if she wants to use them, she can.
After all, she carries a great deal of Merit on her now, and the Heavenly Dao in any timespace would favor those with significant Merit.
It's like how a big company would turn a blind eye to certain actions of an employee with exceptionally good performance.
Sitting on the toilet, Anning was probing the Heavenly Dao Laws.
Then, she placed her right hand on the door, and quickly, the lock outside was unlocked.
Anning opened the door, found a set of storage lockers in the hallway of the classroom, opened one of them, took out a set of school uniforms stored inside, went back to the toilet to change into the clean uniform, and then strutted out of the gate of Shengzhe School with her backpack.
