If it were natural thunder, its power wouldn't be particularly terrifying; generally, Purple Mansion Level cultivators could easily withstand it, but this isn't natural thunder.
This is thunder drawn down by Wang Xiaoqiang using the Thunderclap Palm Technique, a thunder isolated from natural thunder, with immense power; even True Immortals of Myriad Phases cannot resist it.
Boom~~~~~~~
The thunder struck upon the body of the Sky-Reaching Ancestor, causing his body to tremble violently as he spat out a mouthful of black blood, his curses abruptly cut short. The ancestor's eyes rolled back, and he fainted.
The thunder then penetrated through his body, directly striking Wang Xiaoqiang's hands.
Wang Xiaoqiang calmly performed a breathing technique, circulating the mental method to distribute the thunder and lightning throughout his body, refining various cultivation techniques, while making sure a strand of lightning entered the eighth Purple Mansion.
