During the early stages of the Limitless Demon Sect's "Demon Sea Project," Demon Emperor Hezhi dispatched a large number of experts from the Limitless Demon Sect to secretly plant many Demon God Pillars in the Netherworld as coordinates—these Demon God Pillars could serve as coordinates for the Demon Emperor Palace's descent into the Netherworld when the grand project began, while also acting as an ignition point.
The Demon God Pillars connected to the Demon Sea World below and the Demon Emperor Palace above, linking the Demon Emperor Palace and the Demon Sea World together. Song Shuhang knew this entire process like the back of his hand... At the time, he had replaced the Demon God Pillar with the Hezhi Pillar and participated in the final stage of the Demon Sea Project from beginning to end.
And now, between the hundred-plus layers of the Tomb of the Immortal before him and the Tomb of Nine-Rebirth Tyrant Song below, there seemed to be a need for precisely such a pillar to serve as a "link," allowing the two to fuse!
"Go, Hezhi Pillar!" Song Shuhang forcefully hurled the Hezhi Pillar toward the two massive tombs pressing against each other.
This time, the Hezhi Pillar did not leave its sheath. Its pillar body tore through the air and directly planted itself at the head of the "Tomb of Nine-Rebirth Tyrant Song"—then, terrifying Demon Emperor power surged out from its pillar body.
Demon Emperor Hezhi had once toyed with the will of the Black Dragon World, Lady Dragon Network, and the Ancient Nether Will single-handedly. If Song Shuhang had not abruptly intervened back then, Demon Emperor Hezhi might already have succeeded, replacing the Black Dragon Will and the Ancient Nether Will with himself and completely becoming the Heavenly Dao of the Black Dragon World
