Martial Arts Garden.
Book Collection Building.
Jiang Ning tidied up his appearance to ensure he left no trace, then headed towards the Book Collection Building.
...
First floor.
"Good morning, senior!" Jiang Ning smiled and greeted, waited for the Tower Guard to respond, and then headed straight to the second floor.
He knew that the Tower Guard would not respond.
He didn't mind it either.
On others' turf, it's never a bad idea to be polite.
"Is it him?" The one-eyed elder, the Tower Guard, looked at Jiang Ning's back, a thoughtful look flashed in his eyes.
"Impossible!" He silently dismissed his own suspicion, then shook his head slowly, "With his appearance, despite the influence of marrow refining, he's at most around thirty. Moreover, he has only been in the Book Collection Building for a few days, even if he encountered Wind and Thunder Steps, he couldn't possibly comprehend it to Perfection."
...
Second floor.
