Counterattack! Midnight Courier Rules

[Strange stories about rules + suspense and thriller + single female protagonist + online IQ + non-cool writing] Be cautious when entering this trap. This book reveals the truth about Yin and Yang from the perspective of a midnight courier. Starting from the first red package that is forced to be delivered, it travels through the strange city distorted by the system, comes into contact with all kinds of obsessions of dead souls, faces the cold suppression of the Presbyterian Church, and touches the taboo truth at the core of the system... Lin Feng, an ordinary courier rider, received a call from the dead three months after his grandfather passed away "accidentally". An old Nokia that should have been scrapped, a "Fourth Floor" that didn't exist, a red package with his own name written on it as the recipient - "Midnight Delivery Rules" were spread out in front of him, and the identity of "The Ferryman" was forcibly thrown on his head. He didn't want to be a ferryman, nor did he want to send any souls away. He just wanted to find out how his grandfather died. But the rules won't give him a choice. Red packages are only delivered but not received, and you will be responsible for the consequences if they are overdue; knock on the door three times and wait for the cat to meow; do not respond when approached by passers-by... Every code is an iron law of survival written in blood, and the words left by his grandfather at the end of the code: "Only knowledge can break the fog, only caution can save life" became his only guidance. By accident, he discovered that his grandfather's "accident" was not an accident at all, but a carefully planned sacrifice. And he himself has long been designed to be the most critical piece in this chess game.
