"What?!" exclaimed Lionel Yeager in surprise, "A simulated tribulation?!"
"It must be correct!" agreed Justin Chilton, nodding as he said, "I've heard from the elders that one of the hardest trials within the 'Eight Thunder Domains' is the simulated tribulation!
There's the simulated Earth Immortal Thunder Tribulation, as well as the Simulated Celestial Immortal Tribulation!
The White Tiger Ancestor who founded our family set up the trial of the simulated tribulation to let cultivators who enter the trial adapt to the tribulation in advance!
However, generally only cultivators at the Unity Realm Great Perfection and True Immortal Great Perfection who possess extraordinary talent, understanding, and potential, may encounter the simulated Earth Immortal and Celestial Immortal Thunder Tribulations!"
Therefore, cultivators seeking to reach the stage of Earth Immortal must cross the Earth Immortal Thunder Tribulation.
