Chapter 451: North Frontier's Strongest Battle

Xu Yang finally understood, realizing all the secrets except for the one concerning the special taboo sealed within Jingyun Valley. The Night Monarch was unable to provide a definitive answer regarding it.

After all, a power capable of suppressing the leader of the Phoenix clan must be divine in nature, far beyond the reach of mortals.

"It appears now that Jingyun Valley in the Northern Frontier is a formidable place where divine power is sealed. If I truly decide to open this breach, I have no idea what the future holds. A single misstep could potentially alter the destiny of the entire continent because of my actions."

This thought surfaced in Xu Yang's mind, but he quickly regained his composure and fixed his gaze once more on the Night Monarch.

"By revealing these vital secrets, you are also undoubtedly sending me another message: that today, only one of us will leave this place alive."

The Night Monarch smiled and nodded. "Precisely. Only one of us can carry this secret forward. Even if I were not to fight you, the moment you activate the Jingyun Valley restriction, you would inevitably become my enemy. It's better for us to settle this now. If I emerge victorious and absorb your abilities, I will be completely confident in opening Jingyun Valley, even if I don't reach a divine level. Conversely, if you are the victor, the Dark-blooded Demonic Dragon's Dragon Source will naturally be your spoils."

The two supreme powerhouses seemed to have reached a consensus on this matter. Today's battle would not only determine the fate of the entire Northern Frontier but also profoundly influence the destiny of the entire Northern Region of the Three Thousand Dao Provinces.

Should Xu Yang emerge victorious, all the Northern Frontier tribes would once again fall under his control. At that point, Murong Jian, with Xu Yang's support, would become the new leader of the Northern Imperial Dynasty. The Northern Region of the Three Thousand Dao Provinces would then genuinely come under the dominion of Xu Yang's Tianlan Empire.

However, if Xu Yang were to lose this battle, the Night Monarch would undoubtedly seize the opportunity to reclaim his place at the continent's peak.

"Since everything is already predetermined, let us uncover fate's ultimate answer in today's battle!"

*Rumble!*

The next moment, Xu Yang and the Night Monarch simultaneously ascended into the sky. Their battle was destined to use the entire firmament as its stage.

The moment they saw the two ascend into the air, the members of the Xuanmen sect, along with Long Kun and Ling Yao, instantly understood the decision their leader had made.

"It seems we won't need to intervene," Long Kun remarked, crossing his arms casually. "The ultimate duel between these two will determine the fate of the entire Northern Frontier. It's a situation far beyond our ability to participate in or control."

Long Kun, quite relaxed, casually stated this fact with his arms crossed. The others around him, however, gazed up at the two astonishingly powerful figures in the sky, their faces filled with longing and admiration.

Without further hesitation, Xu Yang brandished the Asura Sword, revealing his most formidable power. The Night Monarch, in turn, re-integrated the Dark-blooded Demonic Dragon's Dragon Source into his body, instantly escalating his aura to the peak of the Tribulation Transcending stage.

"Before we begin," Xu Yang asked, "since both you and your brother received the Demonic Dragon's Dragon Source inheritance, is the Dragon Source you possess still complete?"

The Monarch provided a definitive answer: "My brother forcefully stripped the Demonic Dragon's inherited power from his body at the cost of his life and soul. He perfectly integrated his portion of the Dragon Source with mine, making the Demonic Dragon power within me the most complete Dragon Source inheritance."

Xu Yang nodded with satisfaction. "Very good. You are the fourth Dragon Descendant inheritor I've encountered. I'm eager to see the true pinnacle of the Dragon clan's power."

Each time Xu Yang confronted the power of the Dragon clan, he seemed to grow exceptionally excited. He pushed the Asura power within him to its peak, and the familiar Asura God totem once again materialized behind him.

"Asura Path – Dragon Slayer!"

A fervent roar ripped through the air.

Xu Yang unleashed an unprecedented sharpness, shedding all defensive measures and fully immersing himself in a peak state of slaughter.

*Rumble!*

The Asura power cleaved down from above.

An immense surge of terrifying power erupted, and the void crack before everyone expanded infinitely!

"My heavens, he shattered even the void! What kind of power is this, to transcend the laws of the void?"

"These two are merely a step away from true godhood. One possesses the Asura God's inheritance, while the other holds the true Demonic Dragon's Dragon Source. The intensity of their life-and-death battle is truly unimaginable!"

As Long Kun explained to those around him, he continuously released his own power essence to protect his body.

Elsewhere, the Five Element Elders also converged their elemental power for protection, as the destructive force unleashed by the two's peak duel was simply too immense. Standing directly beneath the battlefield, they risked being utterly torn apart by its power.

Above the clouds, the Dark-blooded Demonic Dragon's semi-transformed state rapidly manifested.

The Night Monarch's hands had completely melted, transforming into two genuine dragon arms, and his legs were also undergoing a partial draconic transformation.

Simultaneously, Xu Yang abruptly noticed that his human bloodline was also beginning to partially fuse.

"Strange," Xu Yang mused. "Why is the Dark-blooded Demonic Dragon's power so fully manifested in him? Among all the Dragon power wielders I've encountered, his transformation is the most profound. Fighting him is almost indistinguishable from confronting a true giant dragon!"

As this question formed in Xu Yang's mind, the Sword Spirit of the King's Sword quickly provided an answer.

"The Dark-blooded Demonic Dragon shares similarities with the Bone Dragon I previously slew," explained the Sword Spirit. "Both of these dragon bloodlines possess relatively independent elemental power. In essence, they are elemental controllers within the Dragon clan!"

Xu Yang was immediately enlightened by the Sword Spirit's explanation.

"Are you saying that their Dragon Source power and elemental power crystals are two relatively independent entities?" Xu Yang inquired. "And the Dragon Source can achieve such a high degree of fusion because elemental power acts as a medium, minimizing the mutual rejection between human and dragon bloodlines, thus allowing for a highly integrated state?"

"Precisely!" the Sword Spirit confirmed. "It's the same principle as the Five Element Elders, each possessing a high affinity for a specific element. The Dark-blooded Demonic Dragon's elemental power represents dark attribute energy, which is similar to the inheritance of the Night Dynasty lineage. This is precisely why the Demonic Dragon originally chose the Night Dynasty's twin stars as its inheritors; bestowing its draconic power upon them yielded a far greater effect than it would have on others."

Xu Yang nodded thoughtfully. "So, confronting him will be far more challenging than facing other Dragon Vein inheritors!"

The Sword Spirit calmly nodded. "That is indeed true. However, considering your current foundational strength, if you truly exert your full power, he is still no match for you."

Xu Yang let out a cold laugh. "Naturally. If I can't even defeat him, then I truly wouldn't have the courage to approach the taboo beneath Jingyun Valley!"
