After the Great Catastrophe

In that final, life-and-death moment, Jiang Chengxuan's heart was anything but calm.

That single slash carried the fate of all living beings in the Floodgate Realm. It was the heaviest strike of his life.

Naturally, the blade that slew the Demon Immortal was no ordinary weapon.

It was the reward granted by the system when Jiang Chengxuan killed the wisp of the Demon Immortal's true spirit: the Immortal-Slaying Blade.

This blade contained a singular rule—slay immortals. It could not harm anything other than the essence of beings at the immortal level.

Thus, it was useless against anything but immortal spirits; however, it was lethal to immortals.

When the Demon Immortal began his desperate threats, Jiang Chengxuan conceived this plan. By misleading his opponent with psychological tactics, he finally found an opening to strike.

Hence, the legend of "Immortal-Slaying with One Stroke" began to spread throughout the Floodgate Realm.
