No Turning Back When Walking at Night

Those who hold this umbrella cannot turn back when walking at night. Those who turn back will die. Shen Yan turned around. Not dead. The price is an extra gray spot on the little finger of my left hand, and a gray line creeping toward my heart. There is something sealed in the umbrella. She told him: You have nine more chances. Every time you use it, you have to use Yangshou to offset it. If the umbrella is used up ten times, the person holding the umbrella will die. The night watchman is chasing him, the night master is waiting for him, the shells are looking for him all over the city, and the puppets are watching him in the dark. On the day when the gray thread reaches his heart, how many more times will he have left? Shen Yan insisted on holding this umbrella. Nine times, is it enough for him to survive until the end?
