Traveling Through Time and Becoming a Handyman: the System Helps Me Swallow up and Become a Supreme Being

Time Travel, System, Phagocytosis, highly recommended! The male protagonist [Ye Wuhen] was originally a descendant of a modern ancient martial arts family. After being betrayed by his family, he traveled to the "Nine Netherworld" and awakened his unique talent [Chaos Devouring Body] (the essence of the system). This physique can evolve by swallowing the essence of all things (bloodline/spiritual energy/spiritual soul), but it needs to withstand the "heart-eating calamity" - every time you break through the great realm, you need to kill one of your closest relatives/loved ones/best friends, forming a pull between the "ruthless path" and the "original heart".
