After entangling with this Iron Magnetic Beast for almost an hour, Ye Rong took advantage of the gradually weakening Magnetic Luminous to seize an opportunity. With a stab of his Lightning Sword Light, he directly penetrated this layer of defense and finished off the creature.
With the collections of two Iron Magnetic Beast souls, twelve souls are now in the Hundred Spirits Immortal-Slaying Sword, amounting to 4% progress.
Considering that 96 more spirit beast souls are still needed, it's somewhat daunting. However, compared to the equipment requirements of the Tiandu Sword, this seems much closer, not feeling remote at all.
Indeed, not long after dealing with the Iron Magnetic Beast, a Flying Sword Letter from Blue Chariot arrived, stating that they would start their operation in an hour, asking One Sword Withering and Prosperity to be immediately prepared.
