Qi, the former core programmer of "Apocalypse Games", in the chaos of the game coming to reality, during the global live broadcast of the awakening ceremony, he measured the D-level talent [Data Insight], which is recognized as the most useless - he can only vaguely see other people's "talent values". He was laughed at by the whole audience, his childhood sweethearts broke up on the spot, and his SS-level talent's nemesis even crushed his awakening certificate in humiliation.
When he was about to die, the GM background in Qi's mind was activated: [Retrieve] can see through the data and loopholes of all things, [Edit] can tamper with talents, cultivation levels and even rules, and [Delete] can directly erase the existence of the target.
He disguised himself as a weakling and used his D-level talent as a cover: first, he secretly "edited" his rival's S-level talent to make his aura run rampant during practice; then he used [Search] to find the dungeon bug and get the god-level equipment before the major forces; when facing the hunter, he used only one line of instructions to cause the opponent's attack to "code an error".
As Qi gradually unlocked the permissions, he discovered that the arrival of the game was no accident. The core of the server was being eroded by extraterrestrial evil spirits, and those superior SSS-level talents were just "plot NPCs" generated by the system. In the end, he will use the disguise of a D-level talent to patch the holes in the world with GM authority and fight against the real mastermind.
