Yu Tiangao's "Three Purities Summoning" was a unique and ingenious method he had comprehended after decades of study. It allowed him to summon the ancestral founding masters of Daoism — the Three Purities — to possess him temporarily, granting him the abilities of these patriarchs for a limited time. The so-called Three Purities refer to Taiqing, Shangqing, and Yuqing, who are collectively known as the highest Celestial Gods in Daoism.
Yuqing's Sovereign Lord of Primordial Beginning in the Jade Pure Realm, Shangqing's Spirit-Treasure Sovereign Lord in the High Pure Realm, and Taiqing's Moral Heavenly Venerable in the Great Pure Realm are the supreme lords of the utmost path, the most exalted of all!
