"Indeed!"
Guild Leader Zheng nodded his head, "This formation blueprint was left behind by a 5-star formation master back when the branch was first built. Otherwise, as a 4-star branch, even if we were to apply for a grade-5 formation blueprint from the headquarter, we might not necessarily be able to obtain it!"
The formation blueprints in the Formation Master Guild was as strictly regulated as the pill formulae in the Apothecary Guild. One was only allowed to access resources corresponding to one's current level. If one were to come into contact with advanced topics when one's capability hadn't reached the required level, it would only harm oneself.
As such, 4-star branches like the Honghai City Formation Guild was only qualified to collect grade-4 formation blueprints. If one wanted to access higher grade formation blueprints, one had to apply it from the headquarter and pay a certain price.
