Array King Dane has had enough of the cultivator's world. Fight, kill, grow stronger and fight some more, that was their life style. Cultivation was nothing more than the eternal rat race of immortals and everyone falls at one point or another. Eternity made any odds a guarantee given enough time, and Dane was quitting the game while he's still ahead.
And so he retires. No more fighting, no more killing, no more violence. He's chosen peace, but unfortunately, peace has to be protected.
