"In ancient texts, it is recorded that before the Taoist Ancestor became a Grand Supreme Immortal, he underwent an unprecedented tribulation, which was considered the greatest crisis in the history of the Taoist Ancestor."

"The lightning tribulation transformed into a reflection of the celestial realm, pressing down on the Taoist Ancestor, almost causing his demise even at the peak of the Golden Immortal stage."

"Fortunately, the Taoist Ancestor had boundless methods and successfully overcame the tribulation using various Dao techniques, though he was severely weakened and took several hundred years to recover."
