The Spirit-Devouring Blood Blade was indeed extraordinary. Huo Yuhao could not put it into his Storage Soul Tool and could only hold it in his hand.
Moreover, the Spirit-Devouring Blood Blade possessed an extremely powerful baleful aura, along with intensely concentrated evil resentment.
He had once possessed the Angel Martial Soul and was exceptionally sensitive to evil thoughts. What was more, he now carried a fragment of the Angel God.
Without a second thought, Huo Yuhao moved to purify the blood blade.
After all, even if he transformed it into a Soul Guidance Robot of his own, he did not want his robot to be an Evil Soul Master.
If he transformed it normally, such terrifying resentment and evil energy would inevitably produce a Soul Guidance Robot steeped in evil.
It could very well ruin his plans.
Had it been another type of Soul Guidance Robot, he might have let it slide. But this particular Soul Guidance Robot would be a carving robot, one that would help him engrave Soul Tools and manufacture more Soul Guidance Robots.
Thus, he had to proceed cautiously.
As luck would have it, although he had no Martial Soul with a sacred attribute, he did have the Angel God's fragment.
The Angel God's fragment possessed sunfire and sacred light, making it perfectly suited to purifying evil.
Huo Yuhao placed the Spirit-Devouring Blood Blade within the halo emitted by the Angel God's fragment.
Upon sensing the evil, the Angel God's fragment radiated an even more intense light, completely enveloping the Spirit-Devouring Blood Blade.
An incessant sizzling filled the air. Black mist billowed out, accompanied by black smoke that gave off a nauseating stench.
Huo Yuhao knew that the vengeful spirit within the Spirit-Devouring Blood Blade was being purified. He believed it would not be long before
