The Deceased Please Register Before Midnight

At midnight every night, relic organizer Zhou Heng will receive a gray box. The box contained things left behind by the deceased: a burnt delivery package, a water-damaged tape recorder, and reading glasses with unfamiliar names written on them. But the owner of the first relic was still alive two hours ago. The gray box has seven compartments. Every day that passes, there is one less square. Zhou Heng must find out how a person will die from the relics before the last frame disappears, and change the ending in reality. But every time he saves a person, he loses a piece of his memory. Until a certain point, he received an urn with his name engraved on it.
