"Why don't we go after them now? Maybe we can still catch up?" Nine Lives Cat suggested from the side.

"No need, I can't be of much help if I go," Han Feng shook his head and refused.

In the life simulation, Nangong Xian had a fortuitous encounter, which greatly improved his cultivation and spiritual sense.

During this period, she even surpassed the Nine Heavens Empress.

For Nangong Xianyan, possessing another body would definitely be the most ideal option.

If she misses this opportunity, it will be very difficult for her to defeat the Nine Heavens Empress.

Even with Han Feng's help, Nangong Xian would still find it difficult to defeat the Nine Heavens Empress.

These are the results of Han Feng's two life simulations.

Furthermore, even with Han Feng's current strength, he cannot help Nangong Xian.

Right now, Han Feng's most important task is to improve his cultivation so that he can help Nangong Xian.

He returned this time to exchange everything he took from the imperial tomb for top-grade immortal jade.

Han Feng learned from Shennong Yandi that there were only two or three hundred years left at the end of the era.

Two or three hundred years may seem like a long time, but in reality, it passes by very quickly.

Han Feng needs to raise his cultivation to the Immortal Emperor realm during this period.

Only those at the Immortal Emperor level at the end of an era could put up a resistance.

As for the Quasi-Emperors who are not far from the Immortal Emperors, they are at most slightly larger ants.

Those below the Quasi-Emperor level are not even ants.

Ancestor Baohua and Ruru remained in the Huoyao tribe; Han Feng did not bring them with him.

The desolate wilderness only has a few supreme immortal emperors barely clinging to life, so the threat is not great.

Moreover, the end of the era is approaching, so they will not deliberately target the Fire Radiance Tribe.

At the end of the era, there were ruler-level beings, such as the Heavenly Fiend Water Emperor and the Nine Li Immortal Emperor. It was by no means an easy task for them to survive.

Comparatively speaking, the Great Wilderness is much more dangerous.

The Immortal King of Guangling did not give up the sacrifice, but simply postponed the time.

Behind him stood a Netherworld Ancestor, also a powerful being from a forbidden zone.

The threats of the Evergreen Demon Emperor and the Dragon-Snake Immortal Emperor still exist.

Han Feng did not arrive in the Great Wilderness immediately, but had previously met Leng Hanmei in the Wilderness City.

Leng Hanmei governed the various immortal cities in an orderly manner, and the overall strength of the immortal cities also increased significantly.

It turns out that Golden Immortals were already considered strong in the area, but now they can only be considered average. Leng Hanmei's cultivation has reached the early stage of Great Luo Golden Immortal.

Among them, the four great demon progenitors made the most terrifying progress, all of whom eventually reached the Great Luo Celestial Immortal realm.

The four progenitors—the Extreme Ice Ancestor, the Blood River Ancestor, the Holy Origin Ancestor, and the Six Desires Ancestor—have accumulated power in the Spirit Demon Realm for tens of thousands of years.

Their foundations are incredibly solid, so it's not surprising that they soared to great heights upon arriving in the Immortal Realm.

There are also Su Yuemo, Zhang Yi, and other sect founders. Their cultivation levels are not as advanced as the four great demon clan progenitors, but they are still progressing very quickly.

Their cultivation levels reached the Golden Immortal realm one after another, and their strength far surpassed that of ordinary Golden Immortals.

Han Feng didn't find it particularly strange that these people were progressing so quickly.

Those who have survived for a long time in the spirit and demon realm are all exceptionally talented individuals.

They were simply frustrated because they had no space to use their abilities in the realm of spirits and demons.

When everyone arrived in the Celestial Realm, it was like a dragon entering the ocean, where they could roam freely.

"Han Feng, what realm are you at now? Why can't I tell your realm?"

The divine ape was a reckless fellow who believed in asking questions whenever he didn't understand something.

"I'm now at the early stage of Quasi-Emperor, I just broke through not long ago," Han Feng replied with a smile.

"Early stage of Quasi-Emperor? How did your cultivation breakthrough happen so quickly? You don't cultivate, your method is different from ours," Nine Lives Cat exclaimed in shock.

"We've been stuck at the late stage of Immortal King for who knows how many years, unable to make even the slightest progress."

Goodness, you just went out for a few years and broke through to the Quasi-Emperor realm.

"If you had returned a hundred or two hundred years later, wouldn't your cultivation have reached the level of Immortal Emperor?" The Phoenix King couldn't hide the surprise on his face.

"Han Feng, I'd like to ask, do you accept apprentices?" Black Dragon asked through gritted teeth.

It hesitated somewhat when it learned that Han Feng was looking for the Empress.

Heilong felt that he was much older than Han Feng, so it wouldn't be shameful for him to become Han Feng's apprentice.

Now that it has learned that Han Feng's cultivation has broken through to the Quasi-Emperor level, it can no longer resist the temptation.

If saving face could earn it cultivation and the chance to curry favor with the Empress, the black dragon would certainly be willing.

"Don't joke around, the cultivation method I practice is something you can't cultivate."

Han Feng smiled and shook his head.

He took out four bones from his body, and after these precious bones were taken out, four true spirits appeared on them respectively.

These four true spirits are a true dragon, a true phoenix, a qilin, and a mountain giant ape.

"These are the bones of the true spirit!"

The four demon kings were taken aback.

In the Immortal Realm, True Spirits have a much longer lifespan than ordinary Immortal Emperors.

Some even suspect that the true spirit is a kind of innate deity or demon, whose lifespan should be infinite.

In reality, true spirits simply have a longer lifespan; their lifespan is not infinite.

True spirits are not innate gods or demons; strictly speaking, they should be considered acquired gods or demons.

They grow in specific places; they were originally just some kind of substance that gained enlightenment by chance.

The same goes for Bao Hua, the progenitor, and Luo Hou; both of them were blessed with extraordinary advantages.

As the first being in the Spirit Demon Realm, Rahu possessed immense fortune, which is why he had an extremely long lifespan and profound cultivation.

While others struggled to reach the Mahayana level of cultivation, he was able to cultivate it with ease.

The progenitor of the Treasure Flower was a flower on the Tree of Life, and received much nourishment from the Tree of Life.

True spirits are also considered acquired gods and demons; they too will grow old and die, and their descendants will be passed down through generations.

In order to prevent their lineage from dying out, the true spirit will leave behind a piece of bone from their body to pass on to future generations.

This type of bone is also known as precious bone.

Precious bones are generally only obtainable by pure-blooded descendants, making them extremely rare.

The four demon kings were only heard of; no one had ever actually seen them.

Han Feng actually took out four precious bones at once, intending to give them to his four great demons.

These four precious bones belong to the Nine Li Immortal Emperor.

Han Feng's retreat was hasty, and he didn't carefully examine the spoils of war.

Later, when he gave the spoils to Leng Hanmei, he discovered that there were more than a dozen precious bones among them.

The precious bone contains true spiritual essence and cultivation techniques, each of which is priceless.

This precious bone is extremely rare and very difficult to obtain.

However, during the time of the Nine Li Immortal Emperor, he was the strongest Immortal Emperor, far stronger than the Fire Pattern Immortal Emperor.

The imperial tomb of the Fire Pattern Immortal Emperor possesses such accumulations.

Not to mention the Nine Li Immortal Emperor, the most powerful Immortal Emperor, whose accumulated power is definitely far greater than that of the Fire Pattern Immortal Emperor.

However, compared to the Fire Pattern Immortal Emperor, who was a perfectionist and arranged everything neatly, the Nine Li Immortal Emperor was much more casual.

Another possibility is that what the Fire Pattern Immortal Emperor considered a treasure was insignificant to the Nine Li Immortal Emperor.

Han Feng used a life simulation to absorb all the precious bones, and could even take them out for others to use.

For a long time, the four demon kings were speechless.

The sight of the four precious bones before them made them breathe faster, their faces filled with undisguised excitement.

If those four great demons were allowed to absorb the essence and blood from the precious bone and learn the cultivation methods within, their breakthrough to Quasi-Emperor would be far more than just a simple matter.
