Mu En said to Feng Tianyu:
"Tianyu, kill it."
Feng Tianyu answered, then gave Grey Wolf a look. Grey Wolf immediately unleashed his first Soul Skill, Wind Blade Array.
Blades of wind condensed from Ultimate Wind, sharp enough to slice iron and unstoppable, tore through the Ghost-Faced Lion Mastiff's vulnerable areas—its abdomen, throat, and more—with piercing whistles.
The Ghost-Faced Lion Mastiff possessed formidable vitality. Even with blood spraying from its throat like a fountain and its intestines and organs spilling from its abdominal cavity, it still howled miserably for quite some time before finally breathing its last.
It died in utter agony, truly unable to rest in peace!
A trace of daze flickered through Mu En's eyes. He remembered that Feng Tianyu's first Martial Soul, Grey Wolf, had only been an above-average ordinary Martial Soul a few years ago, and its control over the wind attribute had been merely passable.
