The supreme forgetfulness is not ruthless. Forgetfulness is a person who is silent and emotionless, as if he has forgotten. The speaker was so proud that he forgot to say a word.
Shangqing said: "Disciple Qing Yu, you have been in seclusion for ten thousand years to cultivate the way of forgetting love, but how can you forget love when you don't know it? If your character is not up to par, you will not be able to kill the three corpses. It is better to go to the mortal world and walk a few times to seek some opportunities."
Qing Yu bowed his head and said: "Yes."
