A System-Harvesting Guide for a Background Character in Another World

The moment Luo En opened his eyes, he discovered that he'd entered the world of a game and become a nameless passerby who was supposed to die in the very first chapter.

Even more absurdly, he awakened an omniscient game System that could copy traits, level up through card draws, and claim free rewards.

So while everyone else desperately grinded levels, he focused on exploiting loopholes for free gains. While others fought magical beasts head-on, he used guides and the System to turn the tables. And while everyone else was busy saving the world, he'd already uncovered every hidden resource belonging to the Empire, the Church, the elves, the dwarves, and the dragons.

It wasn't until one day that Luo En realized the System might not be the only thing getting “exploited” in this world.
