Wang Teng was once a good-for-nothing with no cultivation talent, abandoned by his family and dumped by his fiancée. But everything changes when he awakens a daily intelligence system. Relying on the Heaven-Devouring Demonic Art, he repeatedly snatches opportunities meant for prodigies like Xiao Fan and Yan Jiu, seizing beast eggs, phoenix blood, the remnants of an Immortal Medicine, and other precious treasures. By devouring the origins of various special physiques, he rapidly increases his strength. As he ventures into secret realms and travels across different regions, he acquires numerous supreme inheritances and gradually rises to greatness, finally shedding his reputation as a worthless failure.
