Wukong comprehended the Great Karma Technique and, in an instant, severed the cause and effect between the Great Dao Demon Gods and the Great Dao Principles. With his great mana, he transformed them, and the four Great Dao Demon Gods became the four major Protector Heavenly Kings under Wukong's command: they were named Demon-Subduing Heavenly, Demon-Extinguishing Heavenly, Demon-Eliminating Heavenly, and Demon-Removing Heavenly.
These four Protector Heavenly Kings were undoubtedly the most powerful in history. Even combined, the four Protector Heavenly Kings under Tathagata's command and the twenty-four Heavenly Kings could not compare to a single finger of any of these four Protector Heavenly Kings. With a single finger, no matter if it were Heavenly King Bodhisattvas or Buddha Ancestors, all would turn to ashes of calamity.
"Heaven above, he actually transformed four Great Dao Demon Gods into his own Protector Heavenly Kings, what kind of technique is this!"
