Yi Lin managed to understand the promotion system within the Heavenly Sword Sect.
To put it bluntly, it's like a modern big corporation.
No matter who it is, even the Da Qian Princess, upon entering the Heavenly Sword Sect, must start as an errand-running disciple.
Errand-running disciples don't have the privilege of automatic promotion after serving a certain number of years. Just like Chen Bei, who has served for six decades and remains an errand-running disciple despite being the strongest among them.
If one performs well in the Errand Work Class, they might be noticed by a high-level member in the sect and be registered in a certain department, becoming a registered disciple.
As for the worth of being a registered disciple, Yi Lin understood it on the first day.
Gong Yanghei casually took out a series of Waist Badges, each with a corresponding number, and tossed one to Yi Lin offhandedly.
On it was engraved the number — 568.
