Du Busi swung his mountain-sized fists with terrifying power at the massive Taotie Bull.

The two giants collided like planets, unleashing earth-shattering energy.

Booms rocked the sky, yellow and green lights interweaving in a fierce spectacle. Shockwaves swept for miles. If not for Shrek's experts raising barriers, much of the Academy would have been destroyed.

The green giant strode across the sky, each step shaking the world. His fists hammered the yellow bull.

Thunderous crashes echoed. The force drove all onlookers from the sky to safety. Neither side intervened—full war would be disastrous.

Though Du Busi suppressed Xuan Zi, he hadn't used his ten-thousand-year soul skills—he didn't want to force an irreparable conflict. Xuan Zi, despite his anger, restrained his power to avoid harming the Academy below.

In the Pavilion, Huo Yuhao, Wang Dong, and Xiao Xiao watched in awe. The terrifying energy left them pale with shock and reverence. Even through layers of soul power shields, the destructive force was tangible.

At their current level, approaching the battle would mean instant death with no chance to resist.

Mu En narrowed his eyes, also watching the sky. He felt that letting the students witness such a battle would deepen their understanding of true power and spur their training.

But for some reason, Mu En felt a growing unease. Try as he might, he couldn't pinpoint the source. He knew Du Busi was strong, but even half-crippled, Mu En could still suppress him with ease. What truly worried him was an indefinable intuition, a sense that something momentous was coming—something that would affect both Shrek Academy and himself.

Thus, he chose to wait and watch.

In the sky, the battle reached its peak. The two unleashed a massive mushroom cloud, coloring the sky with rainbows. Space was torn apart, a storm of energy ravaged the world.

The green vortex devoured everything, the yellow meteor shower sliced space itself. The green giant grabbed the bull's horns, the two locked in a contest of strength.

With a ripping sound, black cracks appeared in the void, emitting terrifying suction as if to swallow all.

Distant starlight could be glimpsed through the fissures, adding to the scene's dread.

"Du Busi, you madman!" Xuan Zi shouted in anger and frustration.

"Haha, I don't want to die with you, let go!" Du Busi laughed wildly, hurling the Taotie Bull away and retreating from the dangerous zone.

Black rays shot out from the cracks, slicing through everything. A distant mountain was cut in half as if it were tofu, collapsing with a roar and shaking the earth.

As the black light faded, the space began to heal under the world's laws, as if nothing had happened.

Du Busi and Xuan Zi returned to human form, a kilometer apart.

Du Busi laughed mockingly, "Xuan Zi, you're getting weaker with age!"

Xuan Zi snapped, "Old freak, when are you going to die?"

"Bullshit, I'm only twenty years older than you! If you're not dead, how could I be?"

Xuan Zi's eyes lit up—he'd found a sore spot. He taunted, "If you have the guts, live a thousand years, old turtle! Matches your color."

"You're asking for it!" Du Busi, most sensitive about his age, was furious.

He raised his hands, green arcs crackling as a massive green orb formed above his head.

Xuan Zi tensed, transforming again into the Taotie Bull. His horns shone with white light, gathering power.

Du Busi slammed the orb down like a meteor. The thirty-meter green sphere radiated deadly poison, corroding space as it fell.

Xuan Zi unleashed a bolt of white lightning from his horns to meet it.

Boom!

The explosion created massive shockwaves, shaking the sky for kilometers. Du Busi manipulated the green light to trap Xuan Zi, black cracks forming around him with terrifying suction.

Xuan Zi desperately used yellow light to patch the cracks, knowing that falling into the void meant certain death.

Seizing the moment, Du Busi formed another green orb, this time a hundred meters across, turning the sky an eerie green.

Xuan Zi knew this attack was extraordinary. All nine of his soul rings flared, yellow light gathering into a giant weapon—a chicken leg, of all things, his favorite food, now a hundred meters long.

The green sun descended, the chicken leg swept up to meet it.

Boom!

The collision tore space into a massive black hole, its suction pulling in everything nearby—even clouds vanished.

"Not good!" Yan Shaozhe and the others turned pale—the black hole threatened the Academy itself.

"Sigh!" A deep, old sigh sounded.

A dragon's roar split the sky. A golden light soared upward, spreading gentle ripples that isolated the black hole's suction. The golden light repaired the cracks, neutralizing the destruction until the sky was calm once more.

"What…?" Du Busi was wide-eyed with shock. He and Xuan Zi knew they couldn't repair such damage, only wait for the world's laws to heal it. Yet someone had restored it instantly.

"Ultimate Douluo!" Du Busi exclaimed, shaken. He never imagined Shrek hid another peak-level expert besides Xuan Zi!
