Bai Yuan had done many things.
Earlier on, he was interested in chasing criminals from the Otherworld, but eventually found it uninteresting and turned to child-rearing instead.
Hidden within the human Inner World were various "parameters" about humans; modifying some could turn people into complete monsters.
Emotionless, insensible to pain, taking cruelty as desire and killing for pleasure, or having muddled logic, spouting madness.
For Bai Yuan, to thoroughly ponder these matters was definitely more interesting than playing mind games with someone from the Otherworld.
So later on, Bai Yuan stopped involving himself in certain cases because they were not interesting.
It was like a painter who no longer wished to paint suddenly fell in love with sculpting, and from then on, he constantly sculpted his children.
