Now that they were submerged in death aura, their consciousness had already started dissipating and they were no longer able to control that formidable power, causing it to release all at once.
In the sky, fierce clouds converged over several kilometers, and when all the power below had spurted out, the three vortexes instantly transformed into a shockwave sweeping the sky. They simply couldn't see how far that shockwave spread.
The terrifying aura of death spread around the three Heaven Rank powerhouses' bodies. The thick aura of death transformed into a black, ashen cloud that surrounded the place.
Everything within a kilometer was reduced to ashes. The vegetation, the buildings, and even stones... Everything was shattered in a split second, as if they were dying together.
Then, all the clouds started collapsing towards the center before disappearing, along with the corpses of the three Heaven Rank powerhouses.
