The World of Spirits is a different world where spiritual workers are the mainstream, and they contract [professional pets] to fight. There are hunters, berserkers, elementalists, bachelors, etc.
Ye Su, who traveled through time, summoned the spirit servant and awakened two "unknown" [vocational skills]. While others were still [guiding spirits] as "second-born" professional pets, Ye Su had already begun his journey of collecting professional pets, such as Day and Night Double Stars, Six-Eyed Fulong, Bisen Giant Bear, Zetian Rui Beast, Nine-tailed Tiger, etc.
Facing the defeated generals one by one, Ye Su would say humbly: "Actually, I just have too many career favors."
The protagonist is really a bitch
