Xiao Jiuchang's brothers and sisters were adopted by their master when they were young and lived a carefree life on Qingtian Mountain. Until Xiao Jiuchang went to the market as usual, he met the demon troops who were looking for spiritual stones. When his life was hanging by a thread, he was taken in by the demon master as... A male favorite? Only many years later did he realize that it was the junior sister he had long forgotten. (There are male and female protagonists, but no CP; the protagonist will have a darkening and amnesia plot, and the memory will not be restored; the plot will be more sad; if you have a favorite CB or CP, you can make it cute; update from time to time)
Concept: Personal tragedy in a grand era
