Lin Feng, a modern office worker, is unexpectedly reborn in the era before Chaos was formed as one of the Three Thousand Chaos Demon Gods: the Demon God of Karma. He learns that Pangu is about to create the world and that nearly all the Demon Gods will be wiped out! To secure a sliver of life, Lin Feng burns his essence and uses the Law of Karma to narrowly survive the Calamity of Creation, his remnant soul luckily slipping into the Primordial World. With the “BUG of knowing the Primordial World's plot” and the “Law of Karma” as his golden finger, he knows the Primordial World is rife with danger: the Dragon-Han Tribulation, the War Between the Wu and the Yao, the Investiture of the Gods Tribulation, and the schemes of the Saints. From then on, he makes a solemn vow: caution above all, hide whenever possible, make friends far and wide, grow rich in silence, and never attract attention! With an unflappable attitude, Lin Feng becomes the “strongest schemer in the Primordial World.” Using modern thinking and the Law of Karma to stir up trouble in this mythic setting, he watches the mighty figures fight one another while quietly gathering opportunities, growing stronger, and building his own faction. This is the story of how he ultimately becomes the Primordial World's ultimate mastermind.
