Did Li Chengyin, the original author of Donggong, use Lil Feng?

In the original Donggong novel, Li Chengyin had indeed used Lil Feng. In the novel, Li Chengyin was a cold, heartless, selfish, and hypocritical character. He would use anyone he could to achieve his goals. Lil Feng was the princess of Li Chengyin's neighboring country. She was sent by his father as a spy to collect information. After Li Chengyin learned of Xiao Feng's identity, she became interested in her and gradually used her to achieve her own goals.
