"The Strongest Temporary Worker in the Immortal World" (also known as "Let That System Write an Eight Thousand Word Review First")
An irritable young man who works two jobs at an Internet cafe and a barbecue stall travels through the world of immortality on an empty stomach and is bound to a system that is even more panicked than him. He wanted to be a low-income earner, but the system forced him to go through the process, so two "low-level workers" staged a comedy of "mutual harm in the workplace" in the world of immortality.
