At the end of 1999, a strange virus swept the world, and human civilization collapsed within weeks. However, the demise of the old order has become a new paradise for some desperadoes.
Street gangster Ma Tianyou mysteriously acquired a strange ability on the day after the apocalypse - he could see the "bad karma" floating above everyone's head, and he could exchange for survival supplies and strengthen himself by devouring other people's bad karma. He discovered that in this world of moral collapse, the more evil people do, the higher the value of evil karma on their heads, and after he swallows these evil karmas, he can obtain the "karma coins" rewarded by the system, the last god in the world.
While the pre-apocalyptic police, rich men, and gangsters were all struggling to survive in the ruins, Ma Tianyou focused on the thugs who took advantage of the chaos to burn, kill, loot, and commit all kinds of evil. But he soon discovered that those seemingly vicious thugs were just the appetizer for this apocalyptic drama. What really controls this chaotic world is a mysterious organization called the "New Order Council". They seem to hold the secret about the origin of the virus, and are screening survivors in a cruel way.
When Ma Tianyou accidentally obtained a crystal stone engraved with a mysterious code during a hunt, he found that he could no longer look back. Hunting, conspiracy, mutated creatures... A death hunt surrounding him and the crystal began. In this apocalyptic wasteland where there is no law but only power, Ma Tianyou, a mad dog who seems to be the lowest level, is tearing apart the huge lies shrouding the world step by step.
