From that blood light just now, Sunan clearly felt the fluctuation of energy particles.
Thinking of this, he suddenly changed his expression, turned around, and returned to the place where he had just killed the Fine-Jawed Dragon, landing on the ground to inspect the corpse.
Upon inspection, sure enough, the soul aura of these Fine-Jawed Dragons had completely dissipated.
It's normal for a creature's soul to dissipate after death, but there's a process involved, it's not instantaneous.
Yet it's only been two or three minutes since the death of the Fine-Jawed Dragon, and the soul has completely dissipated without leaving a trace, which is absolutely abnormal.
It's more like the soul was extracted rather than dissipated.
Besides that, the corpse of the Fine-Jawed Dragon visibly shriveled, looking as if all its essence had been drained.
"So that blood light was formed by the soul and corporeal essence of the Fine-Jawed Dragon."
