The Heart Demon Blood Oath was not much of a constraint for a figure like the ancestor of the Seven Killings Hall, an almost hopeless Earth Immortal, and he indeed did not trust this person.

To prevent future betrayal and hidden dangers, he can and must kill him now.

Terror-inducing Rule Power surrounded him, and his mighty aura caused the surrounding void to warp unpredictably, swallowing endless Vitality of Killing.

At this moment, Chen Yuan was almost unleashing his full battle strength!

The ancestor of the Seven Killings Hall had a face as gloomy as water, looking extremely displeased. He foresaw the current situation; otherwise, he wouldn't have abandoned the Seven Killings Hall and fled directly.

But when it truly unfolded before his eyes, he still felt a sense of disdain—a mere Demi Immortal showing such disrespect to him, a pinnacle Human Immortal who had condensed Three Flowers—as if he was utterly insignificant.

Courting death!!!

Moluo remained expressionless, ever composed, but this time he did not intend to be a mere spectator. He believed Chen Yuan's strength could rival an Immortal but must surely come at a price.

The ancestor of the Seven Killings Hall was not someone comparable to Xiang Qianqiu, who had just entered the Six Realms. He was a thousand-year-old monster with countless methods, definitely stronger than Xiang Qianqiu.

Surrounding and attacking was the most profitable way for them.

Moluo's thoughts were not wrong; indeed, Chen Yuan currently possessed power comparable to an Immortal and could even summon Chu Grand Ancestor's Seal to face the enemy.

But he was not prepared to use it as a regular tactic.

Firstly, because to summon the Seal left by Chu Grand Ancestor in the Human World requires a significant price. Last time, he was able to force out half of his Essence Blood to summon the Seal mainly because the Seal summoned by Xiang Qianqiu had not completely dissipated, allowing him to easily evoke it.

In other words, it was Xiang Qianqiu who killed himself.

His last words were indeed truthful; he did not lose to Chen Yuan but died by his own hand; hence, after realizing this, he felt dissatisfaction.

If it weren't for him having prepared this trump card beforehand, Chen Yuan summoning Chu Grand Ancestor's Seal alone could even harm his Origin and foundation.

Secondly, and most importantly, is the decision he made after meeting Sima Yuande, which is to treat such means as the true trump card.

Unless absolutely necessary, he must not use it because it could be detected and prepared against, potentially rendering it useless.

His techniques are reserved for the Immortal Domain!

Sima Yuande's words should not be fully trusted, but also not completely distrusted. He had a premonition that the Immortal Domain was not far from descending to the Human World, and its powerful beings could plunge Sima Yuande into despair, indicating terrifying strength.

No amount of preparations would be too much.

The ancestor of the Seven Killings Hall was not worthy enough for him to use such a trump card.

The rusty iron sword reappeared in his hand, and the previously shrunken and withered body of the ancestor of the Seven Killings Hall seemed to rejuvenate, rapidly changing within moments.

Long hair turned black and shiny, complexion became rosy, with sword-shaped eyebrows and starry eyes presenting a youthful and handsome face. If not for the transformation happening right before them, no one would believe this was the ancestor of the Seven Killings Hall from earlier.

"I have cultivated for a thousand years, my power reaching the heavens, having no idea how many lives I have taken, dominating the Human World when you two juniors were yet to be born. Now you dare to be so arrogant, you're truly courting death!" 𝗳𝗿𝐞𝕖𝘄𝗲𝕓𝗻𝚘𝚟𝕖𝐥.𝚌𝕠𝕞

"What is there to boast about, reaching the Human Immortal pinnacle after a thousand years? It must have been cultivated into a dog's body." Faced with the sudden change of the ancestor of the Seven Killings Hall.

Chen Yuan and Moluo were utterly unperturbed, knowing well that this was the ancestor of the Seven Killings Hall stimulating all his life Essence Qi, ready for a death-defying battle with them.

In essence, it wasn't that formidable.

If it truly was, there wouldn't be a need to flee for his life.

"Humph!"

The ancestor of the Seven Killings Hall snorted coldly, sounding like a thunderclap in the flat land. Terror-inducing Rule Power entwined around the iron sword, lightly thrusting forward, and instantly, a ray of gleam appeared in the void.

The eerie grey gleam penetrated space directly, the strong Killing Aura instantly enveloping Chen Yuan. Faced with such an attack, Chen Yuan hesitated not in urging forth the God Slaying Spear, erupting Rule Power in defense.

Moluo closely followed, his thousand-zhang Bodhisattva Golden Body decisively pressing down, the golden light radiating vigorously, illuminating heaven and earth, bombarding towards the direction of the ancestor of the Seven Killings Hall.

The Immortal Battle was about to ignite!

...

"Boom!"

"Boom!"

"Boom!"

The terrifying roaring sound incessantly exploded across the void, mighty Rule Powers interweaving, destabilizing the surrounding void and forcibly breaking the void barrier.

The eerie black holes of the outside world were visible.

The ancestor of the Seven Killings Hall was genuinely using his strongest methods without reservations, with Three Rule Flowers blooming continuously overhead, his body reinvigorated.

Initially, with his desperate measures, he even gained the upper hand, battling two adversaries, suppressing the techniques of Chen Yuan and Moluo directly.

But such advantage was short-lived, merely because Chen Yuan and Moluo were unwilling to engage as recklessly as the opponent would, and within mere moments, everything reversed.

The ancestor of the Seven Killings Hall was strong but by no means a match for Chen Yuan and Moluo. Speaking of Moluo, his strength was no less than that of the ancestor of the Seven Killings Hall.

When truly unleashed, still maintaining the upper hand, he could suppress the opponent.
