In a world of half-elves with low magic, the protagonist Shadow Stone is a silent civilian bounty hunter who silently endures discrimination due to his meager bloodline. During a hunt, the "Perfect World" divine costume design ability hidden in his body awakened, attracting the guild to hunt him down. On the verge of death, he accidentally bound the "Godly Equipment Illusion Module" of the old era system that had serious bugs. The system can virtually manifest the designed BUG-level magical equipment, and can use loopholes in world rules to superimpose power in reality or trigger hidden effects. Shadow Stone used this to pretend to be a pig and eat the tiger, and used "air wall teleportation" and other cool operations to kill the pursuer, shocking the guild. The target readers of refreshing articles can quickly get the pleasure of "technical crushing". While taking on bounty missions to make money, he went deep into the ruins repair system, collected fragments of divine equipment, and cracked hidden bugs. The cool path will go from using bugs to slap people in the face, to exploring the truth of destruction in the "perfect world", and fighting against the hands behind the scenes who are trying to monopolize the truth. The core of value changes from personal survival to protecting historical truth and concealed freedom. The core contradiction is the contrast between BUG-level power and humble status, as well as the conflict between half-elf status and the search for the truth of the world.
