A good modern urban cultivation novel

If the main character was a modern person, he would accidentally obtain some cultivation god book or magic art. Then, he studied, started a company, cooperated with the government, and the government gave him an official position.
Another book was about the main character receiving a divine cultivation book after suffering a blow. It was about a spell that could make the body fat and thin. He had read a little of this book before, in 2005. At that time, it was not finished, but he had forgotten the title. Please help me find it, thank you.
The main character of the book started out as a fat student at school, and only changed after he became a god or a cultivator.
