Security Guard from the Start, Mastermind in the End

He was once a dazzling top student at a prestigious university, but a conspiracy destroyed his family and left him working as a security guard, scraping by amid scorn and ridicule. When fate’s malice drove him to the depths of the abyss, the [Karmic Insight] System arrived right on cue. It could see the connections between all things and predict the paths of the future. Yet he soon discovered that the System offered no easy road, only a more dangerous game. A true hunter never relies on knowing everything. This time, he would make the abyss his starting point, wield wisdom as a blade, use human nature as a shield, and repay every hardship he had suffered.
