After guessing Xiao Yi Xian's physique, Lei Ying anxiously looked behind him.
The purple-black Dou Qi and poisonous mist were spreading into the distance!
They were spreading incredibly fast!
At this rate, the entire Lei Realm would become a Poison Domain!
One had to know that even an outbreak from a Dou Zong-level Calamity Poison Body could turn several miles around it into a dead zone.
If it were a Dou Zun, once the Calamity Poison Body erupted, dozens or even hundreds of miles around it would become a Poison Domain.

"Not good!"
"Stop that Calamity Poison!"
