Huaguang traveled through time and became an oil lamp, practicing silently in the cave of Kongtong Mountain for thousands of years. From a common oil lamp, he cultivated all the way to transcending tribulations and transforming into a human form. The triple heavenly tribulation almost killed him, but he survived. The moment he successfully transformed, he stood on the top of the mountain and roared to the sky, feeling invincible. Then a silver rainbow fell, and Master Xuandu stood in front of him. Hua Guang looked at the only direct descendant of Taiqing Saint, his knees softened and he knelt down: "Senior, I am just a light, don't eat me."
