The Demon Sword Shi Feiyang had not yet undergone sacrificial refinement, unlike the other nine swords; it simply stayed by his side, and it could escape at any time if it wished to.
However, he knew very well that no matter where he fled, unless he reached another world, no corner of this world could hide him from Shi Feiyang, who would inevitably find him and destroy him.
Unless he found a highly skilled Daoist practitioner who did not fear Shi Feiyang to take him under their protection.
If that were the case, why would he not simply stay with Shi Feiyang? Shi Feiyang was emotionally stable, good-tempered, and spoke kindly to everyone; the Demon Sword felt very comfortable by his side.
Shi Feiyang was not worried about it sneaking off, and the sword had no such plans. At Shi Feiyang's command, it flew into the air, transforming into a faint red glow, and in a flash, it was gone.
