Yes, the main character of the novel " Immortal Cultivation: From the beginning of being tempted by the Saintess " had a monster in his body that could devour souls and fuse with the Chakra's nature. The main character of the novel " The Path to Devouring the Starry Sky Bloodline " had the ability of a Bloodline Wizard who could assimilate the body tissues of other creatures to obtain the talent and cultivation aptitude of the race. I recommend these two novels to you. I hope you like my recommendations.😗
