Death of Wang Banxian

In a remote town in Wancheng, there was a famous fortune teller named Wang, known as Wang Banxian. It is said that he is proficient in the Five Elements and Eight Trigrams, has magical calculations, and can calculate all the secrets of heaven. When necessary, he can also eliminate wealth and disaster for people, and change their fate against the will of heaven. It is said that although he is blind, he has a virtuous wife and children. The children are not only healthy but also good-looking. It is said that his wife was fortune-teller. It is said that his hexagram fees start at 100 yuan per hexagram, and rewards are optional. At that time, the market price for fortune telling was 10 yuan per hexagram, which was 10 times that of others. It was still hard to find a hexagram. His house is the most luxurious villa on the busiest section of the town center. Every morning, rain or shine, there is a long line of people waiting for his house. It was said that his fortune-telling was extremely accurate, and his reputation spread far and wide. People from as far away as Shanghai and the capital came from all over the country just to ask for a fortune-telling. How did such a semi-immortal person lead to destruction step by step?
