Under Kieran's [Tracking] vision, he saw souls floating out of the slashed Viper Sect traitors.
The ghosts weren't similar to those mindless, lost wandering souls but a stronger, more vicious form probably in the ranks of specters.
The moment they appeared, the temperature in the temporary base plummet rapidly. Their slashed bodies even withered off at exponential speed and the ghosts grew stronger as though they sucked off the life essence of their body. They were starting to smell like demons
More importantly, the ghosts knew how to work together.
They didn't flood Kieran like what wandering souls did but surrounded him in all directions.
A sharp irritating wail of death later, their sharp claws were lunging at Kieran's weak points.
Sou Sou Sou!
Air-breaking sounds filled the temporary base. The ghosts were originally translucent in form but when a great number of them gathered, it started to affect the material world.
