Programmer Pantian died suddenly in 996 and traveled to the beginning of chaos. At this time, Pangu was besieged by three thousand demon gods. Pantian desperately supported him, accidentally obtained the "Seal of Opening the Sky" and awakened the "Double Cultivation System of Many Sons and Many Blessings". In order to survive in the cruel prehistoric times and resurrect Pangu, he constantly searched for powerful Taoist companions to practice dual cultivation, and used the system to pay for his long life, forcibly improving his partner's cultivation and giving his children heaven-defying talents. From the Calamity of the Fierce Beasts, the First Tribulation of the Long Han Dynasty to the Journey to the West of the Conferred Gods, Pantian was behind the scenes, and his descendants spread all over the world, becoming the saints of various religions and the ancestors of demon emperors and witches. In the end, Pantian accumulated supreme merit and was promoted to the Hunyuan Saint of the Great Dao. In the long river of time, Pangu Yuanshen reunited, and the brothers worked together to destroy the hypocritical Dao.
