Career Zero

Xu Chuan, a programmer who was replaced by artificial intelligence and lost his job, woke up and became an unemployed maintenance worker in a super city in a different world. Here everyone awakens to their profession at the age of sixteen, monsters run rampant outside the city, and the cracks in the city turn into copies at any time. However, Xu Chuan discovered that the unfinished program he wrote before losing his job could actually extract, analyze and synthesize all-vocational skills. What's even weirder is that the remaining 63% of the program comes from himself in the future.
