Novels that are plot-heavy with skillful world building

May involve fantasy elements such as elemental abilities, ranking systems, magical creatures, 

Martial Arts and Wuxia/Xuanhuan elements such as cultivation techniques, arrays

Characters may include Gods, Demons, Sages, Sects, Cultivation Masters, Martial Masters,  Kings and Imperial Family members

Found family & friendship themes are especially dominant amidst trying times like wars, battle between good vs evil, quests on saving the world

Romance may also be included but I don’t particularly like harems.
