The Emperor and his wife stepped back, narrowly avoiding a sweeping blow.

However, before they could even breathe a sigh of relief, a voice rang out: "Brother! I'm here to help you!"

Before the words were finished, the only remaining powerful being in the hall—the Galactic Emperor—couldn't help but step forward and quickly join the battle, helping the Heavenly Emperor and his wife fight against the old bull.

For a time, the four engaged in a fierce melee inside the hall, with neither side gaining the upper hand.

Meanwhile, the other immortals and gods in the hall, though each of them was surrounded by celestial energy and had many believers in the mortal world, were unable to intervene in such a high-level battle.

As the battle escalated, the figures of the four gradually extended from inside the hall to outside, and even into the air.

Their battlefields kept changing, and eventually they emerged from the Heavenly Gate.

High above, amidst the clouds, the four powerful cultivators unleashed their magical artifacts, bringing the battle to a climax.

They clashed back and forth in the air, each exchange triggering massive energy fluctuations, causing the surrounding void to continuously collapse and shatter, forming vortex-shaped black holes.

This thrilling battle shook the distant Heavenly Palace.

Time flies by like a white horse galloping past a crack in the wall; in the blink of an eye, dozens of rounds have passed.

At this moment, although the three of them worked together to attack Lao Niu, they were ultimately at a disadvantage because their cultivation levels were slightly inferior.

On the path of spiritual practice, sometimes the difference of just a hair's breadth can be as vast as the difference between heaven and earth.

At first, the three of them could barely keep up with Lao Niu's fierce attacks, but after more than a dozen rounds, the Galactic Emperor was the first to give up and was sent flying by Lao Niu's powerful blow.

Following two more rounds of fierce fighting, the Heavenly Emperor and his wife were also severely defeated by the old ox's big stick.

Despite this, the old ox still refused to give up and charged forward again with great momentum.

Seeing the old ox coming at them with great force, the three of them took a deep breath, adjusted their state, and charged at the old ox without hesitation.

Thus, the battle between the four resumed.

In the midst of this fierce battle, they unknowingly fought their way from the Heavenly Palace to the skies above the South China Sea.

Then, the two sides moved their battle from the sky to the sea, causing the sea to surge and creating towering waves for millions of miles.

Amidst this chaos, countless fairy islands were submerged and vanished.

At the same time, the underwater palace also shook violently and was on the verge of collapse.

Meanwhile, the aquatic creatures inside the Dragon Palace were terrified and trembled all over.

Just then, the sun and moon rose in the sky, radiating boundless divine light, which descended and enveloped the entire South China Sea.

The stars shone brightly, and wisps of starlight fell continuously, converging towards the Milky Way Emperor.

The sea below surged with boundless waves, but they were quickly subdued by the aftershocks of the four people's fierce battle.

After an unknown amount of time, the battlefield moved out of the South China Sea and back into the inland areas, fighting from the ground all the way to the sky, and then quickly back down to the ground.

A short while later, someone casually broke the Yin-Yang barrier, and the four of them were directly plunged into the Netherworld.

There is also a great emperor in this netherworld. Although he has always been under the command of the Heavenly Court, his own cultivation is not much inferior to that of the Heavenly Emperor.

At this moment, he saw the Heavenly Emperor and his wife, as well as the Milky Way Emperor, besieging the old bull, but he joined in without waiting for the Heavenly Emperor's invitation.

"Haha! Another one!"

"Well done!"

Old Niu didn't care about this at all; on the contrary, his fighting spirit grew even stronger. A seventh-grade white lotus slowly rose above his head, and strands of white light cascaded down from the lotus, enveloping Old Niu's entire body.

With a roar, the old ox gripped his great staff with both hands, his body surrounded by white light. He first swept the staff horizontally, forcing the three Heavenly Emperors back a step, and then smashed the staff towards the Lord of the Underworld.

Seeing this, the Lord of the Underworld hurriedly tried to dodge, but he was still a fraction too slow and was accidentally hit by the force carried by the old bull's big stick. He staggered and spat out a mouthful of blood.

Old Niu laughed heartily: "That was great! Let's have another one!"

Having said that, he once again swung his large club and hurled it at the Lord of the Underworld.

Seeing this, the other three rushed forward to help.

...

As the fierce battle raged on, all four unleashed their magical treasures to fight against the old ox.

A nine-dragon seal appeared above the Heavenly Emperor's head. The seal rotated slightly, and thousands of golden rays descended to protect him.

He also held a precious sword in his hand, which emitted a dazzling golden light.

The Empress held a seven-colored banner, which shone with countless rays of light as it fluttered. In her other hand, she wielded a sword that emitted a cold glint.

A scroll of treasure map hung above the head of the Galactic Emperor. As the scroll unfurled, thousands of starlight streamed down, transforming into silver dragons that coiled around him, protecting him.

At the same time, he also held a sword in his hand, and with each swing, he unleashed a series of sharp sword lights.

Then look at the Netherworld Emperor. At this moment, he also summoned a seven-colored lotus flower, placed it under his feet, and was surrounded by seven-colored immortal light. He held a sword in each hand and stabbed at the old ox in succession.

And so, the four of them surrounded the old ox, turning it around incessantly like a revolving lantern.

They thrust their longswords forward repeatedly, aiming to stab the old ox.

However, the old ox was not afraid at all. He nimbly turned his body and swung his big stick, constantly clashing with the swords in the hands of the four men.

Each impact produced a crisp sound and sparks flew everywhere.

After fighting for dozens of rounds, the old ox finally saw a glimmer of an opportunity. He first swung his big stick, forcing the Heavenly Emperor and his wife and the Milky Way Emperor back, and then raised his hand to unleash a palm lightning bolt towards the Netherworld Emperor.

With a loud bang, a chaotic black and white lightning bolt exploded in front of the Netherworld Emperor.

Seeing that the situation was not good, the Netherworld Emperor tried to retreat, but it was too late.

With a loud bang, the seven-colored lotus flower beneath his feet was struck by lightning and immediately fell to the ground.

The Netherworld Emperor grunted and immediately transformed into a streak of black light and retreated.

Just as Lao Niu was about to give chase, the other three hurriedly swung their swords at him.

With a thought, the old ox summoned a seventh-grade white lotus that floated down from above, circled around him, and then easily deflected the combined attack of the three.

Then, the old ox took a step forward, his figure quickly changing as he chased after the Netherworld Emperor.

He wielded a large club and slammed it down on the Netherworld Emperor. In a panic, the Netherworld Emperor held his sword above his head, attempting to block the attack.

With a sharp clang, the club and the sword collided violently.

Unable to withstand the immense power emanating from the staff, the Netherworld Emperor plummeted from mid-air like lightning.

Before he even landed, he had already coughed up a mouthful of blood.

Although the Netherworld Emperor can be considered a great supernatural being, compared to the Heavenly Emperor and others, he is only at the level of severing one corpse, and his strength is far inferior.

Therefore, he became the key target for Lao Niu's breakthrough.

After only a few rounds of fighting, the Netherworld Emperor had already coughed up two mouthfuls of blood...
