In the seventh layer of the Devil Domain was a mountain. This was the tallest mountain in the seventh layer, and it was known as the Undying Mountain. Not only was the Undying Mountain the tallest in the seventh layer, but it was also the tallest mountain in the entire Devil Domain. The lofty mountain reached straight into the clouds, like a spectacular pillar in the Devil Domain. Even after existing for an untold amount of time, it still stood tall.

Growing on the mountain was a certain type of god-grade plant, the undying grass. A single stalk of undying grass would grant one eternal life, resurrect the dead, and return one's youth. Numerous people had tried to snatch some undying grass from the mountain, but none of the intruders had left alive.

That was because the Undying Mountain was also the Undying Devil Clan's forbidden zone. Only the patriarch could reside on the mountain. The Undying Devil Clan was publicly acknowledged as the strongest warrior race among all the devils.

With their undying body, they could battle until the very last drop of their blood. However, the Undying Devil Clan's ability to reproduce was even worse than the Imperial Nether Clan's, and it was the only thing holding them back from becoming the ruler of the entire Devil Domain.

On the other hand, every single member of the Undying Devil Clan was an elite with a powerful bloodline, capable of growing into a terrifying existence. In fact, the sheer prowess of their bloodline could be the reason their females had difficulty becoming pregnant. Pregnancy was so hard that every single pregnancy would be widely celebrated in the clan.

That day, the Undying Devil Clan had deployed 20 clan members to the Dark Devourer Clan's former territory. Surprisingly, the Undying Devil Clan members looked even more like the humans than the Imperial Nether Clan members. Their males were handsome, and their females were beautiful. If it wasn't for the thick devilish energy constantly spiraling around their bodies, they would look more like gods and goddesses with their flawless looks.

"The Dark Devourer Clan has shown themselves again. I really wonder what they're planning this time. Is the lesson from back then not enough to make them cower and live in seclusion?" muttered the leader of the group while flinging his long hair.

"They probably have a terrifying scheme in play. Unfortunately for them, their return has been exposed," said a woman.

"Whatever their plan is, we need to destroy those ambitious fellows," said someone else.

The group was riding undying birds and heading to the Dark Devourer Clan's former territory at their fastest speed.

...

At a certain place in the Devil Domain was a certain mountainous region. Within the region were numerous valleys. When one looked from afar, the valleys looked like dragons, their resemblance so great the valleys looked alive.

Roar!

Abruptly, numerous dragon roars resounded. One dragon after another flew out. Each was massive with long draconic wings. They tore through the air domineeringly as they all flew in a certain direction.

These were members of the Diabolic Dragon Clan, and 200 flying together was an incredible show of strength. However, not all of them were heading toward the Dark Devourer Clan's former territory. Some were heading to the sixth layer.

"Tell the clan members to move faster to the upper layers and train by fighting humans. When the patriarch ends his cultivation session, we will step into the human world," said the leader.

The Diabolic Dragon Clan was the culprit behind the disturbance in the Devil Domain. Their goal was clear: to invade the surface world. The Diabolic Dragon Clan was no weaker than the Undying Devil Clan; only their ability to recover was lower than the Undying Devil Clan's. However, their reproductive rates were much greater than the Undying Devil Clan's.

They had also mated across species, creating numerous breeds of devils, which was why they were confident enough to invade the surface world. However, the Dark Devourer Clan's reappearance had thrown a wrench into their invasion plan.

Among the three clans, the Diabolic Dragon Clan was the one who feared the Dark Devourer Clan the most. Due to their large bulk, they lacked speed, which made the Dark Devourer Clan their perfect counter. Thus, they wouldn't hold anything back when exterminating the Dark Devourer Clan.

Atop the back of one of the dragons was an exceptionally beautiful woman. The woman was currently tied up by devilish energy, and her face was filled with indignance. Her unwillingness to be a captive was clear for all to see.

Nevertheless, she did not look like she had been harmed much. She had merely been captured. If Xiang Shaoyun was here, he would be greatly shocked. This woman was none other than Ye Chaomu.

How had the Diabolic Dragon Clan captured Ye Chaomu? That was a long story.

In truth, she wasn't an actual human. She was someone Xiang Yangzhan had brought out of the Devil Domain. Her actual identity was an undying devil. Unlike Xiang Shaoyun who was a hybrid imperial nether devil, she was a pure undying devil, which she had long known. Apart from herself, not many people knew this secret.

Not long ago, she had entered the Devil Domain by joining the Devil Hunting Expedition. After breaking away from the 13 eagles, she sneaked deep into the Devil Domain alone, wanting to figure out her true background. When she reached the fourth layer, some devils captured her, and she was eventually handed over to the Diabolic Dragon Clan.

Due to her identity, she was brought to the seventh layer. The Diabolic Dragon Clan was trying to trade her for some undying grass from the Undying Devil Clan. The Diabolic Dragon Clan was confident the Undying Devil Clan wouldn't be stingy in this trade.

At this time, three different groups were heading to the Dark Devourer Clan's former territory. The place was filled with something called the baleful blood poison, a natural barrier the Dark Devourer Clan had created to protect their territory.

The baleful blood poison could rot one's life force and blood. It could also restrain any devil's innate ability, so it had been the Dark Devourer Clan's trump card when they had moved against the three paramount clans.

Of course, the poison was not their only specialty. Like the Imperial Nether Clan, they also had four innate abilities—Devouring Darkness, Devouring Transformation, Devouring Eruption, and Devouring Poison.

Devouring Darkness allowed them to devour all variations of dark energy and corrode everything to form a world of darkness. With it, the Dark Devouring Clan could directly devour any devilish energy attack before returning it back to their enemies. One could say that this was one of their most feared abilities.

Devouring Transformation was an ability that allowed them to assume all sorts of forms and create numerous variations in combat to catch an opponent by surprise.

Devouring Eruption allowed them to self-detonate at any time before regenerating their bodies. So long as they had sufficient dark energy to devour, they could quickly regrow themselves. This was the same ability the Dark Devourer Clan member had used during the sneak attack against Ming Fu.

Devouring Poison was the poison growing on their bodies. Not only could the Dark Devouring Clan devour this poison, but they could also spit the poison out to kill their enemies.

With these four abilities, it was no wonder that the Dark Devourer Clan could become one of the four paramount devil clans.

The true form of the Dark Devourer Clan was rather weird. Each of them was short with a bald head, three oddly-shaped black eyes, a terrifyingly large mouth, spikes growing on its back, a uniquely-shaped tail, and four limbs. Their forelimbs were slim and small, while their hindlimbs were sturdy and strong.
