"Ah~"
The demon howled in agony and turned to flee.
Despite their ability to pin down the demon, there was a significant difference between the Demon Slayer Spike utilized by Perfected Xiao and Thunder Eye employed by Xiao Mu.
Thunder Eye would directly form a beam of protecting evil light, not only sealing the power of swallowing from the demon but also completely anchoring it. The only drawback was that Thunder Eye's attack was rigid and lacked flexibility, making it easy for the demon to dodge. Therefore, Xiao Mu needed Stone Soul and Wood Spirit to assist in restraint.
The attack of Demon Slayer Spike was more flexible, much like a magic treasure, it did not require others to help with the restraint. The downside was that it could only seal the demon's power of swallowing, unable to pin down the demon.
Therefore, the demon pinned by Perfected Xiao's Demon Slayer Spike could still run away, and its combat power had not decreased at all.
