After both became badly injured, they chose to flee.

Their buddha worlds were both in badly broken states, missing limbs all around. Even their immortal buddha trueforms were no longer whole. If they continued fighting, they would die for sure.

As maniacal as they were, they still dearly wished to live.

Therefore, after they were severely injured, they simultaneously backed away, preparing to flee and lick their wounds.

Wu Yu already had his eye on one of them. After keeping the others in the Floating Dreams Pagoda, he used Lawful Embodiment of Heaven and Earth to shrink himself and zoom over to them.

If Wu Yu was remembering correctly, he was currently chasing Nanwu Treasured Moon Buddha.

If he was in peak condition, Wu Yu was no match for him. But as injured as he was, he was barely at 30 percent of his full strength.

Combined with Luo Pin and the others, it was possible that he might be able to take him down and ask some questions.

Even now, Wu Yu was still badly shaken by the fight between the two immortal buddhas.

Especially the grisly sight where they had slaughtered billions all for a few moments of strength. It made him feel that the Heavenly Buddha's Domain was an alien place indeed.

Here in Heavenly Buddha's Domain, mortals had no status. Even the bodhis were but like ordinary immortals in the sky palaces. In the eyes of these immortal buddhas, they were but fuel, food, and energy.

In battle, these billions of lifeforms were expendable. To the immortal buddhas, they would disappear in a few thousand years anyway. They could simply create a new batch of life, and build their resource bank again.

Although those who had reached bodhi level stood a chance to leave the buddha world, but there was no immortal qi or spiritual qi in space for these ordinary bodhis to cultivate with.

After leaving the buddha world, these ordinary bodhis would eventually expire as well, as they did not have eternal life.

"Seems like the immortal buddhas here are really the lords! Besides immortal buddhas, nothing else here has a say. Even among them, they exchange blows before words. It's...... like a barbaric world."

These were Wu Yu's thoughts for now.

And no ordinary world would end up like this. After all, there were so many immortal buddhas in Heavenly Buddha's Domain. Where did they start from?

They too must have cultivated step by step as mortals. If Heavenly Buddha's Domain had been like this from the start, there would not be very many immortal buddhas.

Which meant that mortals born into Heavenly Buddha's Domain were very unlucky. Only death awaited them.

They existed on the immortal buddha's worlds. If the immortal buddhas started fighting recklessly and wiped out all life on them, it was extremely unlikely that any of them would ever cultivate to immortal buddhahood.

It was even more impossible for mortals to rise here than in the Heavenly Domain. It was already near impossible for mortals to rise to immortal emperorhood in the Heavenly Domain.

If they were expended in a random surge of destruction during their cultivation, they would all fall without the slightest chance of resistance.

Wu Yu thought back on his own journey. Even if he had the Great Sage, Heaven's Equal's legacy, he would definitely be unable to make it this far if he had been born in Heavenly Buddha's Domain.

In Heavenly Domain, as long as he did not do anything rash, there was nothing that others could do to him. He could remain around those of his level. Even Yan Huang Ancient Emperor had only been an ordinary immortal.

If Yan Huang Ancient Emperor had been an eternal immortal emperor like the immortal buddhas here, where would Wu Yu be today?

This barbaric, savage world held no hope for mortals.

Wu Yu was sure that the Ruyi Jingu Bang had brought him here for a reason. He could not miss this chance. He had to get to the bottom of this.

And one way to do so was right before him.

He tailed the badly injured Nanwu Treasured Moon Buddha, heading deeper into Heavenly Buddha's Domain as he bid his time to strike.

Wu Yu recalled that back when he had first started cultivating the Invincible Vajra Body, there had been a tier called the Nanwu Treasured Moon Golden Vajra Body. The buddha that he had envisioned back then was exactly the same as the Nanwu Treasured Moon Buddha before him now, except that one was golden while the other was black.

Thinking back to what Golden Bodied Immortal Buddha had said, Wu Yu was even more convinced now that his Invincible Vajra Body had come from Heavenly Buddha's Domain.

Nanwu Treasured Moon Buddha limped away, deeper and deeper, oblivious to the fact that he was being tailed.

Finally, he crawled into a dark space, settling down to recuperate. Such heavy wounds would take tens of thousands of years to fully heal.

Just as he relaxed, Wu Yu struck.

He was good to take on a badly injured Nanwu Treasured Moon Buddha. Plus, he had Luo Pin and the others to help him. This was not the Immortal Emperor Trials, where fair and square individual duels were fought.

"Heavenly Dragon Unification!"

Luo Pin knew what she should do. As Wu Yu readied himself to strike, she turned into the snow-white mystical dragon and merged with him!

Full Moon of Nanshan and Ye Xixi were not slacking off either. Each used their own moves against Nanwu Treasured Moon Buddha.

Of course, their Mystiques were not offensive, but disorienting. Combined with their elite epochal immortal treasures, Nanwu Treasured Moon Buddha was surrounded by many phantoms which he struggled against.

Nanwu Treasured Moon Buddha had reacted instantly to their attack, but in his weakened state, even getting free of the illusions took him considerable time.

And in that time, his chance was lost.

"Ruyi Jingu Bang, Vertigo!"

With the Ruyi Jingu Bang in hand, and Luo Pin's Heavenly Dragon Unification with him, he dealt a terrific blow to Nanwu Treasured Moon Buddha's head and knocked him out!

Even if he was a third tier Supreme Immortal Buddha Realm cultivator, Nanwu Treasured Moon Buddha was too badly wounded to defend against the Ruyi Jingu Bang's Mystique, and he fainted.

By the time he woke up, the four of them had already trussed him up good, preventing him from escaping.

"Who are you!" Nanwu Treasured Moon Buddha glared at them furiously.

"Answer our questions properly, or we'll kill you!" Wu Yu warned him sternly.

Nanwu Treasured Moon Buddha could sense the immortal emperor aura from him. He knew that he was not Wu Yu's match in his weakened state. He needed time.

"You're not from Heavenly Buddha's Domain?" Like Golden Bodied Immortal Buddha, Nanwu Treasured Moon Buddha immediately sensed their different backgrounds.

Wu Yu was not surprised. After all, immortal emperors and immortal buddhas were too different. Anyone could tell them apart, let alone an immortal buddha.

He was not going to answer the immortal buddha's questions.

"It's us asking the questions now! Remember that, or you die here!" Wu Yu demanded harshly, intending to intimidate Nanwu Treasured Moon Buddha.

The black immortal buddha trueform was given a proper scare. In his weakened state, he could not even muster his anger, too afraid that he would die. After all, immortal buddhas had eternal life. If he died he would have nothing.

"Ask then." Nanwu Treasured Moon Buddha finally submitted, calming down and cooperating.

However, there was still a tinge of violent anger in his eyes. If the chance presented itself, he would kill them all. He was merely pretending to be calm.

They looked at each other. Finally Nanwu Treasured Moon Buddha was tamed.Now they could get some answers.

"How many immortal buddhas are there in Heavenly Buddha's Domain?"

Wu Yu asked first. For him, the number of them would help inform his decisions.

"About 100,000 maybe." Nanwu Treasured Moon Buddha answered immediately. It was common enough knowledge in Heavenly Buddha's Domain.

Wu Yu continued: "Why are all the immortal buddhas I've seen black?"

Nanwu Treasured Moon Buddha sneered in response: "Buddha worlds are all black, aren't they? You're an immortal emperor from Heavenly Domain, damn it. You don't even know a thing about Heavenly Buddha's Domain? What are you even doing here?"

"Speak honestly! And cut the crap!" Wu Yu threatened him with the Ruyi Jingu Bang.

Being interrupted was very annoying.

Nanwu Treasured Moon Buddha fell silent again, afraid that Wu Yu might actually kill him. His faint glower still lingered.

"Alright, continue then. All the immortal buddhas in my mind are golden. Whether buddha worlds or immortal buddha trueforms, they're all golden?" Wu Yu elaborated. This was quite an important question.

After hearing this, Nanwu Treasured Moon Buddha was a little confused. What was with this kid and these basic questions?

He replied: "All of the immortal buddhas and buddha worlds were originally black! Only the Buddha Above All is golden."

"And who is this Buddha Above All?"

As Wu Yu asked, he saw that admiration filled Nanwu Treasured Moon Buddha's face. "The Buddha Above All is the greatest being in all of Heavenly Buddha's Domain!"
