"Ancient texts record that before Taozu became the Primordial Supreme Immortal, he faced an unprecedented tribulation, which was considered the greatest crisis in his life,"
"The Heavenly Tribulation transformed into a reflection of the Immortal Realm, pressing down on Taozu, nearly extinguishing his life and Tao when he was at the peak of the Golden Immortal Realm,"
"Thankfully, Taozu had limitless means, successfully applications of various Tao techniques allowed him to survive the calamity, but he was severely weakened, taking him a few hundred years to recover,"
"Taozu thought that it was a tribulation that had to be faced to become a Primordial Supreme Immortal, but neither Confucius, Buddha, nor the later Yuanzu or Immortal Emperors, encountered such a tribulation."
