Heaven Reader

Han Feng downloaded a Tianting reader and found that the authors in it all came from a place called Tianting. Han Feng realized that he was starting to become prosperous, so he gave him a small reward, and the author gratefully gave Han Feng some small gifts from heaven. What will happen if I write a novel and send it to Tianting Reader? With so many merit rewards, what should I buy? Kung Fu, magical weapon, or panacea?
