The Yin-Yang Cage

In the 21st century, rifts in space and time tear open, and the cosmic torrent floods the land.

The Nine Provinces' seal, shaken for a thousand years, begins to tremble. Countless evils beneath the earth howl to be set free, humanity becomes a living hell, and civilization teeters on the brink of collapse.

The six Immortal Masters' remnant souls return to their places, and a hundred thousand special forces troops temper their bodies into an army.

The bloodlines of the families sworn to guard the seal have grown faint; the remnant souls of their ancestors burn their spirits to hold the line.

They temper their bodies with crystal cores, relearn secret arts, and cross oceans to seize power, all to fight for one slim chance at survival.

No one knows that the fiends beneath the earth are only an appetizer.

The true darkness of the ages, the ultimate cosmic beings, are still slowly opening their eyes in the depths of the starry sky.

In this life, he will use the apocalypse as a furnace and forge an immortal from a mortal body.

If he cannot hold them back...

then humanity will be buried with this world!
