It wasn't about how Aidan acquired his dragon transformation ability.
Of course, as the Adventurer profession he had personally crafted, Mo Fei took the Thunder Dragon Knight very seriously, too. The more splendidly this profession performed in plot events, the grander his status as the grandmaster of the profession would be.
There were two methods to design the professional abilities of a Thunder Dragon Knight.
The first was for the profession mentor to set the game role for the profession, and then the system would automatically generate abilities based on the setting of the profession's background. As for what skills could be produced, only heaven would know, but generally, the system was quite reliable. The generated skill set would be relatively complete and balanced, and it would certainly fit the profession's setting.
