The century-old post office hides a Yin and Yang delivery shop. Delivering Yin and Yang letters is a life-threatening task. If you violate the rules, you will die. The heroine Shen Zhiwei was accidentally bound to the delivery shop contract due to her grandmother's secret and was forced to join the game.
2. The heroine: She is a restorer of ancient books. She does not understand the rules and is weak in strength. She only relies on the bronze seal left by her grandmother and her calmness and reason to survive.
After completing the first life-or-death delivery, I met teammates such as Chen Jingshan and Lin Sui. I initially understood the rules of the delivery shop and the threat of "weird contamination", and realized that the delivery shop is not a simple life-and-death game.
