The combat ability that could instantly kill anyone isn't worth mentioning for now.
The most terrifying part was,
Tan Bingtang had not found any trace of this formidable person in the surveillance of the nightclub and the surrounding areas he could investigate, yet this person had appeared out of nowhere.
Came without a shadow, left without a trace.
Not a single clue could be traced, as if he were a wandering ghost.
Such formidable stealth ability coupled with that kind of combat skill, was definitely a top-tier assassin that could keep anyone from sleeping easily.
Tan Bingtang had never believed in the existence of such outrageous assassins like those in the movies but now, he believed— even feeling that those movie assassins were somewhat underplayed, that the portrayal was too modest.
