When Li Yao spotted that female thief, he had already decided to stir up trouble, making the ogres and gamers duke it out to mutual destruction.
Li Yao considered himself neither a saint nor a villain. He wouldn't harm others without reason.
The key problem was that those thieves were just too despicable, always resorting to underhanded tactics because they knew how to stealth.
If it wasn't for Li Yao, the other players would probably be victimized, especially with a horde of five thieves roving around, stripping even the gleaming master players bare.
When Li Yao encountered such scumbags, he would outscumbag them, making them wish they had never been born. He wouldn't be content unless he'd cleared their corpses at least five or six times.
However, due to time constraints, Li Yao could only manage to kill them once.
