Once, Chen He polished off a bunch of hired killers (who seemed to be after him?), and eventually found the mastermind.

Mastermind: You’re gonna kill me after ten years! Of course I’ve got to make a preemptive strike.

Chen He: …

Chen He: Sir, we have had no bad blood between us, and I have not done anything to offend you. Why are you being so threatening?

Taoist priest: Hmph! In the future, you’ll be offending me to no end. Haven’t you been looking down on me all your life?

Chen He: …but I still have my entire life ahead of me!

Antagonist A: Chen He! Because of your master, I was rejected by XX Sect, and so I was forced to become a demonic cultivator!

Chen He: Who…who are you?

Antagonist B: My future lover’s meridians and good looks were ruined by you, and I’m definitely not gonna let you do it this time!

Chen He could not help but think: There is definitely something wrong with my life!
