One Silver Dollar Vampire

One silver dollar was not scarce in this era, and people sometimes used silver dollars for divination and making wishes. So does Major Star. How do you judge your safety when you need to watch your way down a ravine with no bottom? Therefore, at the beginning of the story, he dropped a silver dollar into the ravine and heard a quick and crisp echo. This shows that it is safer there. The bottom may not be an abyss, at least it is not very high, and even if it falls, it will not be a serious fall. Besides, he is a professional explorer. So he stayed with the long ravine and trekked through the long night until he reached the end of the story. He thought he had finally gotten rid of the pursuit of the past, and when his weather-beaten soul could rest, he was horrified to find the silver dollar he should have invested at the starting point in the corner at the end. He jumped into the ravine - and then he saw a monster standing in the abyss, holding countless thick silver coins in his hands, picking up and throwing them down one by one, and the echoes continued to spread, misleading those who tried to explore. When the monster saw Major Star, he smiled with joy and horror. "Hey, you're finally here." He said, "I've been waiting for you for a long time... From the time you set out to the time you came back here." "You made those noises on purpose." "But you need this echo... You need to know that it is safe, don't you? I just tried to give you some small comfort, and you also got the end." The monster chuckled. "As reward, stay with me. You won't refuse, right?" *Under overhaul *Atypical Western Fantasy *Settings are complicated *he, but in the broad sense he. *Old treacherous, cunning and perverted attack×Conscience is still tired and suffering "You have to know that cheap products often don't have good products.
