In fact, Lu Ping'an's "Great Path" had already been determined.
Before becoming a professional, he was the Mother Goddess's headwind. His ability trait was, of course, completely opposite to hers.
"The Mother Goddess takes life to strengthen herself, which is selfish and egocentric..."
Lu Ping'an's "Life Investment" was about sharing his own life force and pursuing mutual development.
This was the starting point, but it also vaguely determined his evolutionary direction... There's no need to mention the low-level Gardener profession, as those are just foundational, general professions.
From the fourth tier on, Lu Ping'an's traits became quite clear...
"The fourth-tier Life Investor enhances my Talent Abilities, expands applications, and increases limits..."
Lu Ping'an's "direction" was set, and he had no objections or dissatisfaction; it was simply the most suitable path for him.
