book and the manga are more closely related than the anime. The anime doesn't really follow the plot-that much anyway. but for the book you should read at ch. 16(that's where the translation ended right now.) As for the anime, probably ch. 22(I'm not confident for that one. Haven't watch all of the available ones(only watch till ep6)

Start from chapter 17 , as in read chapter 17 and maybe 16 if u still don’t understand. Please note that chinese novels are very descriptive so you may find a clashing difference between the manga and the novel in terms of understanding the plot . Plus they changed a lot in terms of plot sequence and storytelling in the anime so it’s kinda useless when u want to continue the novel, the manhwa on the other hand is the closest to the novel
im planing to read the novel and i want to know which chapter should i start with since im already reading the manhua and watching the anime ??
