When Wu Yu arrived in the Demon Immortal Realm, the Buddha Above All, Xuanzang, also did as he was in Wu Yu's Apotheosis Realm.

However, Xuanzang suggested it would still be better to return to the Expanse of Nirvana for cultivation. On one hand, the spiritual qi was denser in the Expanse of Nirvana. On the other, the Demon Immortal Realm might be discovered by the Jade Emperor if he recalled he once' invaded the place.

If that happened, it wouldn't be as easy for Wu Yu to escape to the Heavenly Buddha's Domain.

In fact, the Jade Emperor might even find out the existence of the Heavenly Buddha's Domain when the Immortal Domain Bridge was opened. Then, the Heavenly Buddha's Domain would be in a perilous state.

The Immortal Buddha World Core was now damaged, causing all the immortal buddhas to become ruthless and savage. The environment was abominable and even Xuanzang couldn't alter the current situation.

Wu Yu naturally heeded Xuanzang's suggestion and decided to bring the group to the Expanse of Nirvana to cultivate.

Obviously, he still had reservations of Xuanzang. He didn't trust him a hundred percent although he couldn't see anything wrong about the Buddha Above All currently.

Wu Yu wasn't going to just look at the surface. Instead, he would also analyze from a deeper perspective and concluded Xuanzang wouldn't need to deceive him. His explanation of the two immortal domains was reasonable without any suspicious points.

Since Wu Yu went through the incident with Yan Huang Ancient Emperor in the Jambu Realm, he always kept his vigilance up for everything.

When he became the disciple of Patriarch Bodhi previously, he was also cautious about it.

Subsequently, Jade Emperor despatched celestial soldiers to capture him. To Wu Yu's surprise, Patriarch Bodhi was willing to pretend he was defeated by Wu Yu so Wu Yu could escape. It was only then Wu Yu was certain that Patriarch Bodhi was someone he could trust.

However, he still had doubts of Xuanzang and couldn't trust him completely.

Obviously, Wu Yu couldn't tell anything amiss with the Buddha Above All and felt the suggestion was great.

Therefore, Wu Yu took Luo Pin and the group to Heavenly Buddha's Domain to continue cultivating.

In the Demon Immortal Realm and Eternal Emperor Tomb, immortal qi was too scarce. Cultivating in this place would be too ineffective.

Even if Wu Yu wanted to achieve growth by devouring eternal demon emperor corpses, he wouldn't have to stay here all the time. Instead, he just have to return from time to time. This could also greatly limit the risk that Jade Emperor would find him.

Luo Pin, Full Moon of Nanshan and Ye Xixi had inherited the legacies of Eight Division Heavenly Dragon, Marshal Tian Peng and Curtain Lifting General respectively. Wu Yu and the group could all be considered as grand disciples of Xuanzang.

When they arrived in the Expanse of Nirvana, Wu Yu and the group addressed Xuanzang as Grandmaster.

Other than the four of them, Wu Yu also took Jiu Ying, Ming Long, Wu You, Su Yanli and Princess You Xue into this place.

After all, if they remained in the Heavenly Domain, they might encounter dangers due to their relationships with Wu Yu.

Su Yanli, Princess You Xue and Wu You could even cultivate in Wu Yu's Devouring Apotheosis Realm. Wu Yu had now constructed the heavens in his Devouring Apotheosis Realm. Immortal qi filled the realm and the concentration was high.

After all, Wu Yu's Devouring Apotheosis Realm was filled with energy from innumerable peaches. To this point, there was still lingering energy from the peaches within his Devouring Apotheosis Realm.

For Wu You and others, this was sufficient for their cultivation needs for a long time.

Their days in Heavenly Buddha's Domain became more relaxing.

Wu Yu and the group cultivated on their own. They sparred from time to time to exchange their new insights in cultivation, furthering their progress.

Benefits from such exchanges were huge and especially so at the immortal emperor level.

Wu Yu had devoured numerous eternal demon emperors and immortal buddha. From them, he had learnt various cultivation paths that were meaningful references.

Finally, 30,000 years later, Wu Yu finally raised his golden buddha world to the same sixth tier Devouring Apotheosis Realm.

As immortal emperor, he's a sixth tier immortal emperor. As an immortal buddha, he's at the sixth tier Supreme Immortal Buddha Realm.

When using both powers in coordination, Wu Yu's battle strength could be raised to new heights.

If the time he took to defeat Elderly Lord and raid the Heaven's Prison was considered long and was the reason why Jade Emperor discovered it, he could probably do so again in half the time.

This was a huge improvement.

When Wu Yu achieved the sixth tier for his buddha world, he also created the River of Time and heaven in his buddha world. With both worlds, more mortals achieved immortalhood and the pace was twice as fast as immortal emperors or immortal buddhas of the same tier.

Therefore, the increased in Wu Yu's battle strength was especially swift.

The buddha world and the Apotheosis Realm together helped Wu Yu perfected the legacy of the Great Sage, Heaven's Equal. However, he was definitely still weaker than the Great Sage, Heaven's Equal in the past.

At the very least, the seals on the Ruyi Jingu Bang had not been fully removed.

If the seals on the Ruyi Jingu Bang could be fully removed, his battle strength would definitely escalate again.

In the 30,000 years of cultivation, Xuanzang also helped Luo Pin, Full Moon of Nanshan and Ye Xixi create their buddha worlds. He also guided them in their cultivation.

On the path of immortal buddha cultivation, Wu Yu and the group still had many doubts despite receiving their legacies.

Whenever they had doubts, Xuanzang would be able to answer them, fulfilling his duties as their grandmaster perfectly.

Over the 30,000 years, although they didn't meet Xuanzang frequently, they always felt enlightened after Xuanzang guided them. They would find the path ahead easier and crossed any bottlenecks.

Over time, Wu Yu and the group began to trust Xuanzang further.

Their time in the Expanse of Nirvana was probably the most peaceful period since they started cultivating.

As the Immortal Buddha World Core in the Heavenly Buddha's Domain had shattered, the other immortal buddhas had become ruthless and savage.

However, in the region of the Expanse of Nirvana that Xuanzang controlled, the immortal buddhas wouldn't dare to cause an upheaval. After all, the other immortal buddhas were well aware of Xuanzang's strength. If they stir up troubles in the Expanse of Nirvana, they would even be expelled from it.

When that happened, they would lose a relatively secured cultivation environment and might die to the black immortal buddhas outside.

Over time, Wu Yu felt the Buddha Above All, Xuanzang, was jkust like a saviour. With his own strength, he maintained the final order of the Heavenly Buddha's Domain.

It was also so that Xuanzang organized the Pilgrimage of 10,000 Buddhas to get sufficient divine sarira to construct the relatively secured Expanse of Nirvana.

Otherwise, the entire Expanse of Nirvana would have collapsed completely. As for the Heavenly Buddha's Domain, it would be plunged into the most terrifying and darkest chaotic era......

When his Apotheosis Realm and buddha world had both reached the sixth tier, Wu Yu was finally prepared to go for the seventh tier.

He first choice was naturally his Devouring Apotheosis Realm. He had to create the Sea of Heavenly Dao within his Devouring Apotheosis Realm!
