Nine-Colored Divine Thunder, Five-Colored Mysterious Fire.
This is a product of the Chaotic Universe, and an extremely formidable Heavenly Tribulation.
If Gai Tianyuan were at his peak, unscathed by the Lord of All Spirits, with his cultivation back then, he wouldn't regard the Nine-Colored Thunder and Five-Colored Mysterious Fire as threats.
