Before the End: the Remaining Warmth of the Candy Wrap

Warm reminder: This is a mysterious fantasy novel with suspense features, not pure suspense. Introduction: Gao Yuan's thirty-eighth candy was given to him by his sister before she died. When he saw the message on the candy wrapper, he realized that his sister's death was not an accident... This is a world hidden in the gaps of the rules, where obsessions serve as locks, candy wrappers can serve as keys, and the destinations of all "fate-tracers" are untraceable.
