Dragon Siphon, Waterspout

"Rumble!" Another large bolt of lightning struck with a loud roar, turning the sky dark purple. 

"Poof!" On the surface of the sea in the distance, a water pillar surged skyward all of a sudden. It shot into the dark clouds in a split second, connecting the sea to the storm. 

The Boundless Sea Douluo Chen Xinjie's just managed to say, "Is that a Dragon Siphon?"

A Dragon Siphon was also known as a waterspout. It was a tornado on the sea that would only appear under exceedingly rare circumstances, but it was highly destructive. It was a combination of the wind and water. More importantly, the appearance of a Dragon Siphon had a significant effect on a person's mind.
