The Heavenly Dao leaves one ray of life amid forty-nine possibilities. Xuan Ming, originally a modern person, transmigrates to the ancient primordial world and becomes the innate supreme treasure, the Two Poles Wheel. After taking human form, he becomes a disciple of the Saint Laozi, the Heavenly Venerable of the Way and Virtue. He hears the Dao Ancestor preach three times and earns his favor. After the third sermon, the Dao Ancestor bestows upon him a Primordial Purple Qi, along with the innate supreme spiritual treasures: the Two Poles Bell, the Two Poles Daoist Robe, and the Two Poles Sword. After the Investiture of the Gods, he senses that the time to prove his Dao is near, so he reincarnates as Tianming. Unexpectedly, he encounters a tribulation of humanity. Overcoming it will let him become a saint on the spot, but this tribulation is no easy feat...
