Year 1226 of the Advent Era.
Twelve hundred years ago, the virtual reality game Universe descended into reality. Monsters invaded, and the world was rewritten.
Liu Ming transmigrates into Blue Star and, on the day he awakens, gains the one and only hidden class, "Gunslinger," which combines the four branches of Ranger, Mechanic, Heavy Gunner, and Munitions Expert.
Yet the first thing he does is disguise himself as the most ordinary mechanic.
That's because he has also bound himself to something called the Sixfold Caution System.
The System's mission: create the strongest, most cautious trickster.
Completing cautious-path missions earns Rage Points. The more others lose their cool, the stronger he gets. He plays the pig to eat the tiger as part of his daily routine. Secretly messing with people is basic practice, and finding bargains until his opponents break down is standard procedure.
To the outside world: a mechanic with the lowest combat strength, an ordinary person with average luck.
In reality: skills from all four awakened branches take turns lighting up the battlefield, while his trickster tools keep everyone guessing.
"You think I'm competing with you in strength?"
"No. I'm just waiting for you to lose your cool."
