The sky was densely covered with dark clouds. Standing at Elder Sun's location, one could clearly see the clouds flickering with lightning, as if it were ready to strike down at any moment.
"Heavenly Tribulation..." Elder Sun, already a mighty cultivator of the Nine Realms who had faced such tribulations, realized what was happening immediately.
He shouted in alarm to Zhang Tianci, who had just emerged from a crack, "Tianci, be careful!"
"This Heavenly Tribulation is terrifying indeed, and without full preparation, facing it means almost certain death."
"In such a case, no one can help you, you must withstand it on your own."
…
Elder Sun himself had a profound experience with Heavenly Tribulations.
Years ago, when his Primordial Spirit entered the tribulation, he was nearly struck to death by the lightning, barely surviving.
His already worried expression now completely changed.
