Suddenly, behind him, a horrifying aura suddenly surged up; this aura was so terrifying, it felt even stronger than the aura of Immortal Lord Han Feng and Immortal Lord Shuangji!

Moreover, this aura came straight for his back.

This aura was incredibly terrifying. Even with his current physical body, if he took this hit head-on, he feared he would be severely injured in an instant.

Cao Zhen had no choice but to instantly redirect all his immortal energy into his Immortal Palace. In an instant, numerous Great Walls emerged from his Immortal Mountain, and the mountain enveloped him completely.

With his full exertion, his Immortal Mountain, which stood at 9,999 feet tall, was fully revealed.

Boom!

Cao Zhen only felt a continuous, horrifying impact on his back. Numerous Great Walls kept collapsing, yet the sword in his hand still thrust forward.

Although this sword strike lacked dense immortal energy due to his need to defend himself, its speed remained sufficiently swift, and the Sky Clan member ahead of him never expected to be ambushed by the human they had allied with. This sword thoroughly penetrated the opponent’s body.

But at the same time, a terrifying force came from behind, propelling his body forward.

Though his Great Wall Immortal Palace blocked the opponent’s attack, that terrifying impact couldn’t be fully stopped.

He turned his body while rushing forward, glancing back.

To Cao Zhen’s left and right, Immortal Lord Han Feng and Immortal Lord Shuangji remained unaffected. They, being at the peak of the True Immortal Realm, ambushed and directly killed two Sky Clan cultivators!

However, their expressions soon turned solemn as well, having realized the ferocity of the attack aimed at Sect Leader Cao! They immediately turned, guarding Sect Leader Cao’s side, and simultaneously looked at the woman opposite.

Instantly, an enormous Immortal Palace came into their view!

It was an extremely beautiful and magnificent Immortal Palace, adorned with agate, jade, luminous pearls, and various gemstones. Each gem seemed to be a treasure, and at a glance, there were at least a hundred such stones!

"Transfiguration of Immortal Palace! Perfect Completion of True Immortal Realm!"

Immortal Lord Han Feng’s gaze instantly became serious.

Even though there were six peak True Immortals on their side, they all had nine Immortal Palaces.

But the one opposite possessed ten Immortal Palaces!

The opponent almost injured Sect Leader Cao with a single attack, a terrifying strike that couldn’t possibly be achieved by a cultivator with just one Immortal Palace.

Obviously, the opponent had fused all ten Immortal Palaces into one!

It wasn’t just the group; the sudden change also caused the Sky Clan to stop their attack on the human clan, glancing at Cao Zhen’s trio and then at the transformed human clansman with the Immortal Palace.

Immortal Lord Zhu Sha looked at the 9,999-foot-high Immortal Mountain. A serious expression appeared on her face as she slowly uttered a few words: "Hundred Peaks Sect Leader!"

Seeing such a towering Immortal Mountain, there was no need to think—it must be Cao Zhen of the Hundred Peaks Sect.

All around, members of the Sky Clan noticed the towering Immortal Mountain. Each had a look of horror in their eyes; Cao Zhen of the human clan was indeed present here.

He was a terrifying existence capable of severely injuring or killing twenty Sky Clan experts. Among them were even half-step Golden Immortals.

Now their numbers were less than twenty, and the human clan’s strength was not weak either. With Cao Zhen here, how could they fight?!

Escape!

They instantly thought of escape!

Suddenly, Immortal Lord Zhu Sha’s voice rang out again.

"Don’t run; for Cao Zhen to kill so many, his secret technique’s range of attack is exceedingly large. If we flee, we play right into his hands.

In contrast, with so many humans here, if we engage these humans in battle, he’ll fear harming them. Naturally, he won’t dare to use that Secret Technique. Only then do we have a chance!"

With that, she was the first to charge towards the humans!

As soon as she finished speaking, the Sky Clan also reacted, rushing towards the humans. But unlike before, their goal this time wasn’t to slaughter the humans in front, but to cause chaos.

Just as the Sky Clan cultivators charged out, suddenly, a pair of semi-transparent wings appeared behind Immortal Lord Zhu Sha, with a wingspan of about one zhang.

As the wings flapped, her body suddenly took a turn, flying rapidly into the distance.

The idea of fighting with the opponent was not what she intended at all; she intended to escape!

Cao Zhen had defeated twenty True Immortals with even a half-step Golden Immortal present; they couldn’t compare at all.

She merely wanted the Sky Clan to charge to create chaos.

With the flap of her wings, the Immortal Palace behind her fully erupted, flying towards the distance with astonishing speed.

"Still want to escape!"

Behind Cao Zhen, tricolored divine wings emerged, pursuing the fleeing Immortal Lord Zhu Sha.

He was very adept at speed, yet in pursuit, the distance between him and Immortal Lord Zhu Sha grew increasingly larger.

If this continued, it wouldn’t be long before Immortal Lord Zhu Sha would be lost.

As he watched Immortal Lord Zhu Sha getting farther away, Cao Zhen’s form abruptly transformed, instantly turning into a massive roc, rapidly chasing after the opponent.

Ahead, while flying, a look of surprise suddenly appeared on Immortal Lord Zhu Sha’s face—how did Cao Zhen’s aura vanish and get replaced by another aura?
