Amid the violent, thunderous roar—

Yu Chao'an hung in the air, dumbstruck, blank for a moment, even the movements of his hands quietly stalling.

Force this terrifying — belonged to a Fortieth Den demon emperor?

And besides... hadn't the creature struck the wrong target?

Just then, he found the lion shooting him a cold glance.

"Hiss."

Yu Chao'an shuddered, and only then came back to himself.

He resumed manipulating the formation, casting out two small mountain peaks along the way and smashing them viciously at the flood dragon.

Never mind what the situation was.

Slaying the Dark-Tail Demon Emperor first was always the right call, at any rate.

Boom! Boom!

The mountain peaks shattered, scattering into a rain of falling rock.

The Dark-Tail Demon Emperor took two more heavy blows, its massive body writhing, its ferocious head abruptly gaping open. "Have you gone out of your goddamn mind?!"

Shen Yi, swept by the reeking gust, leapt up once more.

Before the old flood-dragon could close its mouth, a fist bearing vast force crashed into its lower jaw.

Its whole body went flying sideways, tumbling endlessly across the ground, only to be dragged forcibly back by those four pillars of fire.

"Hkk... hkk..."

Blood in its mouth, it finally understood why this lion had the strength to trade blows with Zhang Xuanyan — yet it still couldn't fathom why the creature had turned its claws on it.

Within the Thousand Demon Den, however great a dispute might run—

when facing human cultivators, they always presented a united front against the outside.

"..."

Watching the lion come charging in again, the fury and murderous intent in the Dark-Tail Demon Emperor's eyes boiled to the utmost, and it loosed a piercing wail: "You want This Emperor's cave estate, you want to sit in This Emperor's seat, you base cur! What monstrous ambition!"

The creature wasn't the least bit content merely to replace the Thunder-Hoof Demon Emperor.

The place it truly wanted to occupy was the Sixteenth Den!

At this moment, compared to Yu Chao'an, the Dark-Tail Demon Emperor wanted far more to slay…
