[Urban high martial arts + system + imagination + anti-routine + upgrade flow]
The whole world is fighting monsters and upgrading, but I am the only one writing bug reports.
On the day of my eighteenth awakening, I became the only F-level test engineer in the entire system, with a combat power rating of 1. While others are flying and escaping, I can see the bugs in this world. Boss is invincible? Submit a bug report and the shield will be broken for you on the spot.
Until a message from three thousand years ago popped up at the bottom of the system: "Welcome back to the team. We have been waiting for a long time."
There is another message from the "Backdoor Club": "Find him. Shoot to death."
