Four months later.
At the border between the Path of the Nether and the Land of the Three Kings, a battered and incomplete undead army slowly emerged.
Huang Yu sat atop Taotie and looked back, still shaken.
"Even a sleeping Immortal undead would be beyond me with an artifact's blessing..."
Recalling his experiences during the past six months of campaigning through the Path of the Nether, Huang Yu felt a wave of fatigue well up inside him.
For the past six months, he had been fighting almost every week.
At first, he had fought the Nether Marks forces on the Path of the Nether.
With his formidable personal strength and elite undead army, Huang Yu had almost never lost a battle.
All in all, he had obtained nine Nether Marks.
Later, many undead forces, including the Forest of the Dead, Rotten Bone Forest, Rotten Flesh Mountains, and Plateau of Ten Thousand Souls, began taking action against Huang Yu as well.
The subordinates they sent were at least Seventh Tier Saint Domain-level undead.
Moreover, every wave was led by Legendary undead.
Although Huang Yu was extraordinarily powerful, these Legendary undead still harassed him relentlessly.
He had set a trap midway and wiped out seven Legendary undead and more than a hundred Saint Domain undead in one fell swoop.
Only after displaying his strength to the various undead forces did the coveting and harassment from the major forces of the Netherworld begin to lessen considerably.
It was not until he reached the borderlands of the Path of the Nether, where Huang Yu led his troops into the territory of the Undead Monarch Istara, that the previously invincible Huanyu Troops suffered a devastating blow.
Of the million elite undead, fewer than one in ten remained. Of the fifteen Bone Giants, only seven survived.
