Express Delivery at the Beginning: I Signed for the Ghost Order

As soon as the package was opened, the bleeding shadow figure suddenly stood up and stared at me with his red eyes: 'Lin Shen, it has been ten years and you are finally here. ' The phone screen buzzed with a scarlet warning: The rules for signing for strange objects are activated. If not completed, the strange objects will be permanently bound! From that night on, red express messages kept popping up on my phone - the cursed wedding letter would sing a wedding song at midnight, and the old pocket watch would suck away half of the recipient's life every time it moved around. Fortunately, every time I solve the monsters, I can unlock the 'Spirit Insight' and 'Suppression of the Monsters'... But they don't know that I don't just want to survive - those webmasters who defrauded my salary and the gangsters who bullied my sister should all have a taste of being entangled by the monsters. Until I found out that all the senders of the express delivery pointed to the 'faceless man' on the night my sister disappeared ten years ago, and the 'strange resonance body' hidden in my body was the most dangerous bait in this situation..."
