The Son-in-Law God Emperor

'''Xiao Fan, the useless eldest son of the Xiao family, was beaten half to death by his own younger brother and sent off to marry the ugly daughter of the Long family in exchange for cultivation resources. By sheer chance, he awakened the supreme treasure of the cosmos: the Celestial Star Map. With every shattered star, he gains the treasures within—spiritual artifacts, spirit stones, divine herbs, and cultivation techniques. The path of the Dragon Elephant Tyrant Body begins, forging an indomitable physique. Thus unfolds the tale of a worthless son-in-law defying the heavens to claim his throne.'''
