This is kinda like a survival story at the present time.. where everything is so expensive. The character can't do farming or anything like a Chinese ancient time. So, the main lead has to do something else to make money for a living. As his Qi is very useful, he took this opportunity to use it to upgrade his life such as in working or in school. I think if he worked in the entertainment industry, there would be a scene in which he would absolutely use Qi to help with his acting. By the way, I'll keep reading this novel till the end. No regret for sure :)
