With the roar of the Purple Flood Dragon, a tribulation thunder fell and struck the Purple Flood Dragon's body, instantly enveloping the Purple Flood Dragon inside. A fierce roar was heard from the thunder light, and the Purple Flood Dragon's huge body was also rolling over, trying its best to resist the power of the Lightning Tribulation.
The Purple Flood Dragon didn't have any magic treasure, it could only rely on its own flesh to resist, so it was naturally extremely difficult to resist the robbery lightning, In just a blink of an eye, a crack appeared on the Purple Flood Dragon's huge body, the scales of the purple flood dragon were constantly falling off, blood was spilling down, and the ground was dyed red.
Feng Yun was shocked by the power of heavenly thunder, he has read in the book that if someone wanted to cross the boundary of the heaven profound realm, he has to cross the heavenly lightning tribulation.
