Li Yao went to see a doctor and told him he had depression. Life on the continent of Valoran was harsh and bitter: no internet, no Wi-Fi, no stress-relief forums or Weibo, no anime or seasonal shows. Such a life left him, a transmigrator, so utterly desperate and sad. The doctor comforted him, saying, “Although we can't cure your depression, the continent of Valoran is about to end. We're all going to die, whether sooner or later, so it's perfectly normal to be depressed.”
Li Yao angrily demanded to know why the doctor wouldn't let him go watch the Joker for a laugh. “That's what you always used to do.”
The doctor lowered his head and forced a smile.
“But I'm the Joker.”
Hearing the doctor, Li Yao lowered his head too and forced a smile.
“I forgot. You're just my ultimate ability.”
