It's a life-and-death struggle!""Let me ask you, there is only one spiritual stone here, who will take it? To put it bluntly, I must kill you!""In fact, at the beginning, I was also a good person! Don't be afraid, I am very powerful, killing people is just a matter of one blow!"…"Even if all seven emotions and six desires are gone, I still laugh at the Supreme Forgetting Emotions and Being Free""I know I regret, this is why I don't regret!"
