This book tells the story of the programmer Lu Yaoyao who unexpectedly became a temporary patch to fix the bugs in the "Three Realms System" after his sudden death. He discovered that the so-called fairy world was actually a virtual "sandbox" that needed to be maintained, and his immediate boss, the cold administrator Su Jin, had a cruel bond with him that "kill him nine times to save the world."
In the process of fixing outrageous bugs such as "Jade Emperor account crash", Lu Yaoyao teamed up with "old colleagues" who had awakened, such as Sun Wukong and Nezha, to fight against the traitor Chi You who intended to format the world. During the crisis, he fought side by side with Su Jin, choosing to risk upgrading rather than destroying the system, and eventually became the founder of one of the top managers of the system as "Patch".
However, they later discovered that even this "real world" seemed like another sandbox. Bai Qiming, the mastermind and system architect behind the scenes, surfaced. He regarded all living beings as experimental data and initiated a destructive formatting protocol. Facing the ultimate crisis, Lu Yaoyao did not choose to fight. Instead, he gathered the will of all creatures in the world to "want to live" and wrote the ultimate code to allow the imperfect world to continue. In the end, while shouldering the responsibility of protecting each other, he and Su Jin also protected each other's little happiness and continued the daily life of "BUGs can never be fixed".
This is a story about saving the world by repairing codes. The core explores why emotions, memories and imperfections are precious amidst cold rules and grand destiny. It celebrates the glory of those mortals who still choose to repair rather than delete and protect rather than destroy in desperate situations.
