Wu Yu led the other three out into the vast expanse of Heavenly Buddha's Domain.

They could not split up here. If the other three met another violent immortal buddha, they would be overwhelmed.

Therefore, the four moved together in a single direction, searching Heavenly Buddha's Domain.

They did not know how long they had gone, when suddenly they heard a deafening din in the distance, as though two immortal emperor-level beings were in a huge fight.

This caught their attention.

"Let's go take a look."

They exchanged looks and headed towards the sounds of battle.

From afar, they could feel the shuddering impact of powerful attacks reverberating through the air.

"It's two immortal buddhas fighting!"

As they neared, they saw that two immortal buddhas, both at least at the third tier of the Supreme Immortal Buddha Realm were fighting. They were far beyond Wu Yu's cultivation realm.

Their fight was so titanic that Wu Yu and the others did not even dare to get close, and they watched from afar.

Behind these two immortal buddhas were their black buddha worlds. Just like the Golden Bodied Immortal Buddha, they were fighting in their immortal buddha trueforms.

Even at this distance, Wu Yu could see that the black buddha worlds were full of mortals and ordinary bodhis, teeming with life.

As for the two immortal buddhas, their fight was so intense that some of the attacks spilled over into their worlds, taking lives.

"Nanwu Treasured Moon Buddha, how dare you be so insolent! You will die for your crimes! Take this; Virtuous Buddha Palms!"

One of the black immortal buddhas yelled. He summoned a black palm that flew towards the other black immortal buddha. Along the way, it churned through the void itself.

"Nanwu Virtuous Buddha, I insist on disrespecting you. What are you going to do about it? Die now!"

The rage of the other black buddha was equally towering, and they lashed out at each other with vicious attacks that shook their worlds.

Even from a good distance away, Wu Yu and the others could feel the impact of their attacks. They were considerably stronger than Wu Yu. If he was to face either of them, he would be defeated in a few moments.

Also, Wu Yu still had no idea why they were fighting.

It seemed to be over some disrespect?

The situation seemed unclear, but they seemed as reckless as Golden Bodied Immortal Buddha.

"Could it be that just some words caused them to fight?" Full Moon of Nanshan looked at them hurl abuse and attacks at each other.

"No idea what the situation is. Let's keep watching. They can't get us from here either." Ye Xixi was very curious too, but they could not get any closer for information.

If the immortal buddhas turned to attack them, they could only flee like rats.

Nanwu Treasured Moon Buddha and Nanwu Virtuous Buddha. The two were locked in a heated battle, screaming vulgarities as they tried to tear the other to pieces.

They seemed even more unreasonable than the Golden Bodied Immortal Buddha.

It seemed like this world was steeped in grudges, the only-one-can-live kind.

If such a battle occurred in the Heavenly Domain, there would definitely have been some deep hatred between the two. It seemed like they were already resorting to their last-card type of Mystiques.

All their majestic buddha techniques and Mystiques were laid out, an all-in bid to do the other in.

Despite all of this, listening to their argument for a while, Wu Yu and the others realized something.

Which was that the two immortal buddhas did not have any grudge at all. Both had merely bumped into each other in Heavenly Buddha's Domain.

And then one had looked the other the wrong way, and the other had taken it the wrong way, cussing back.

Neither had been willing to back down, and the overflowing emotions had led to this deadly battle.

Wu Yu and the others were absolutely confused.

"It can't be. Just looking each other the wrong way, and they're at each other's throats?" Luo Pin could not believe what she was hearing.

But from their argument, this was indeed the case.

Nanwu Treasured Moon Buddha and Nanwu Virtuous Buddha had no enmity to speak of. To begin fighting even before a single word had been exchanged, it was uncanny.

It seemed like the two immortal buddhas had lost all reason, going feral on each other. They had let their impulses run wild.

Both fought desperately, risking their lives to fight with unfettered, reckless abandon. Even if their moves would injure themselves seriously, they used it.

The void continued to crumble around them, and soon both were heavily injured. Even so, they did not show any sign of retreating. The verbal abuse continued, and then the violence.

Finally, they seemed to expend all their energy with one final move each. Unable to take it anymore, they both retreated into their black buddha worlds.

In the next instant, they started to fuse into their black buddha worlds, and the two huge black buddhas began to move.

"They wouldn't be going to fight in their buddha worlds, would they?"

Wu Yu and the others stared, horrified.

Their buddha worlds were home to billions of lifeforms, whether mortals or ordinary bodhis, or even other forms of natural life. They were all individually insignificant compared to immortal buddhas.

Once the buddha world was attacked, all life on them was doomed!

As they watched in sick disbelief, the two immortal buddhas indeed began fighting in their buddha world forms.

The two huge black buddhas grappled with each other. The mortals must have thought that the world was ending. As they clashed, each buddha world was protected by a black force shield. Still, each clash saw countless mortals die!

One could almost label it an epic and magnificent sight, if one could but look past the horrific scale of death.

These two immortal buddhas, Nanwu Treasured Moon Buddha and Nanwu Virtuous Buddha, fought on, heedless of the deaths on their worlds.

Towards the end, the two buddha worlds used a final blow simultaneously. Both absorbed all life on them into the core of the world, which was the immortal buddha's core.

They had absorbed the billions of lifeforms in one go, converting them into raw power.

All life immediately crumpled down, their vitality sucked out of them ruthlessly!

After devouring so many lifeforms, the two buddha worlds grew incredibly strong. They threw themselves at each other again.

It was a raw and physical grappling, but both were backed with so much strength that the void groaned and rumbled under their efforts. Even from their safe vantage point, Wu Yu and the others were shaken badly.

The third tier Supreme Immortal Buddha Realm cultivators were much stronger than the first and second tier cultivators.

They fought at a level where Wu Yu could not even intercede if he wanted to. With the power of worlds behind them, a slight movement on their part would sqaush Wu Yu to bits.

They continued to throw punches and kicks at each other, the worlds crashing horribly as space around them continued to be rent apart.

And as their battle grew fiercer, both their buddha worlds started to show signs of damage.

First it was an arm of one buddha being ripped off, although the other's arm was ripped off at almost the same instant as well.

It was an extremely gory battle. No blood flew, but the size of their bodies made the violence extremely vivid.

The two buddha worlds continued to rip each other to pieces, wounding the other so badly that neither could recover in a short time.

"It's insane. That's a fight between immortal buddhas? It's more direct than the immortal emperors' fighting, that's for sure!" Full Moon of Nanshan exclaimed.

He was appalled by the complete genocide of all life on the two buddha worlds, a repulsion deeper than he had ever felt before in his life.

The only thing that had come close was the scene of Demon Immortal Realm in the Eternal Emperor Tomb.

"Seems like they can't take it anymore. They're going to run away." Luo Pin noted.

This made Wu Yu and the others perk up.

If they wanted to know what was going on at Heavenly Buddha's Domain, perhaps it was best for one of these immortal buddhas to fall into their hands!
