On his birthday, 15-year-old Tang Yun received a mysterious key, which was engraved with ancient and mysterious words. But when Tang Yun woke up, he had already appeared at the opening ceremony of Arkham Academy. What's even more terrifying is that this was the year 1690, when Arkham College, the predecessor of the University of Michigan, was officially established. After all, Tang Yun knew Arkham, a land of outstanding people and Salem with simple folk customs. But what was even more frightening was that when Tang Yun learned that this was the fictional world of Cthulhu, he even took his own life. What should he do? This is a question worth thinking about. After all, those indescribable gods give people a headache just thinking about them.
