Before the End of the Open Beta, I Will Fully Master the Hidden Professions.

"Boundary Marks Online" tester Lu Xing fell asleep while working overtime, but when he woke up he became border adventurer Ren Shiraishi. There was a grayscale panel that only he could see floating in front of him: [From public beta archive: 89 days] [Can be transferred to: Chain Realm Envoy (not yet installed/will be deleted after the public beta test)] [Recommendation: Practice your proficiency to Lv.50] The whole server is charging for warriors, mages, and priests. Renn looked at the professional card that had been sentenced to death by his own evaluation report and smiled. "Okay, then I'll finish practicing it before you delete it." From the guild mission board to the salt spray cave, skills are lit up one by one. Teammates said he was cutting the air, and the next second the boss fell. Open beta closed after ninety days. Just when everyone thought this career would disappear forever, Renn's proficiency bar just came to an end.
