The author has been frustrated with System novels for a long time, and the unreasonable Systems have nearly driven them crazy. That's why they wrote this book.
Gou Huo dies in a mental hospital. Thanks to his bizarre yet consistent reasoning, he passes the afterlife civil service exam and becomes a guide for the dead. After his superiors discover that many people who should have died have failed to return to the afterlife, they send him to investigate. These people have used various means, such as transmigrating, being reborn, and foreseeing the future by transmigrating into a book, to use Systems to overwhelm the locals. They defy the laws of life and death and disrupt the local ecosystem. Most of them are concentrated in a place called Jiang City.
Gou Huo learns that these people always try to win others over and blend into everyday life by frying eggs. So he infiltrates Jiang City as an egg seller. While guiding them back to the afterlife in accordance with the rules, he discovers the "System," a digital parasitic virus. His assignment is extended indefinitely, and the confrontation keeps escalating under the pressure and power of all kinds of Systems.
