The protagonist is born with knowledge of swordsmanship, Taoism, Buddhism and demons. They are integrated into one body and are born to be the overlord. He cultivates immortality from humans step by step: integrating Confucianism, Buddhism, Taoism, Yin-Yang and Five Elements, Heavenly Stems and Earthly Branches, Feng Shui and Kanyu, and ancient mythology (three emperors and five emperors, prehistoric gods). Practitioners of each system need to conform to the corresponding cultural and Taoist charms (for example, Buddhism and Taoism practice "compassion to overcome adversity", Yin-Yang Taoism follows "Unity of Heaven and Man").
