Xu Yinglian's face turned pale.
As a member of a Cultivating Immortality family, she had long understood the terrifying nature of Heavenly Tribulation from various ancient texts.
However, it was only when she truly witnessed the Heavenly Tribulation before her that she realized all the records in the ancient texts had severely downplayed its actual power.
Each bout of Tribulation Lightning was a thick electric serpent, capable of easily tearing through all kinds of Daoist Magic, and could only be shattered with a high-rank Immortal Sword or a powerful Magical Treasure.
And there were hundreds, if not thousands, of such bolts of Lightning at the same time...
As the tribulation clouds grew denser, the serpentine lightning became even more intense, forcing Qiu Changtian and Xu Yinglian to retreat once again, to avoid being harmed by the tribulation's aftermath.
