I'm Not a Craftsman I

When the "black tide" swallows civilization, and when human skills are forgotten, a group of inheritors who have awakened to the "Craftsman's Way" use their own skills to fight against the coming end. "A craftsman has his unique skills, and his unique skills can lead to spiritual enlightenment." Fifty years ago, a gap opened in the sky, and a strange substance called the "Black Tide" poured out. It won't hurt people directly, but it has a terrifying ability-devouring information. In places soaked by the black tide, all records of the "past" will disappear: books turn into white paper, hard drive data returns to zero, and human memory becomes blurred. The most terrible thing is that the knowledge and skills swallowed by the black tide can no longer be re-invented.
