Terror Resurrection: the Rise of Yama

Eighteen years after his soul traveled to another world, Xu Dayou still has no awakening system. Is this reasonable? The answer is obvious, this is unreasonable! What should I do if it's unreasonable? Fortunately, this is a world where terror revives and weird wanderings occur. Since there is no system, I will create one myself. Otherwise, wouldn't it be embarrassing if the senior time traveler finds out about it? This novel and its characters are purely fictitious.
