He goes against any common sense using his wits and novel knowhow to finish missions and arm himself against his cruel fate.

I am the best when it comes to taking divergent paths. With just a flip of my hand, I shall take the path less commonly travelled. I search far and wide, only to find myself unbeatable and unrivaled. So now I ask, who else can match my awesomeness?

Life and death bore me and I do whatever I deem fit.

“Young man, way back when I started acting tough, you were still learning how to put on your underpants!” Xu Que thus decided to take the path of acting tough. He decided to act tough every single god-damned day. If he wasn’t acting tough, he was scheming for the best way to act tough!
