An ancient lotus lamp that can burn away all illusions uses emotion as its fuel; a handyman with useless spiritual roots who attaches great importance to emotions becomes stronger the more he uses the lamp, and becomes less and less human.
He originally lit the lotus lantern to protect the people he cared about.
But every time he lit the lotus lantern, he burned away his emotions; by the time he was strong enough to protect everyone, he no longer cared about anyone.
