Jiang Chen finally understood, after comparing the content on the animal hide scroll, why the Spirit Coffin Palace Lamp seemed even more eager than the Immortal Extinction Sword Seal upon seeing it.
This was because the Innate Spirit Lamp seal left on the animal hide scroll was identical to the Spirit Coffin Palace Lamp. In other words, the Spirit Coffin Palace Lamp was once a part of the complete Immortal Slaying Formation.
With this thought in mind, Jiang Chen suddenly took out the Spirit Coffin Palace Lamp and placed it before the animal hide scroll.
Hum hum hum...
The animal hide scroll trembled, the Innate Spirit Lamp seal on it lit up, radiating dazzling brilliance, resonating with the Spirit Coffin Palace Lamp.
At the same time, the dim light on the body of the Spirit Coffin Palace Lamp also became flickering and unstable; then, as if breaking some kind of seal, deep demonic qi burst forth from the dark flames within it, sweeping outward.
