Yue Mian transformed into a cyan giant bird, spreading its wings and soaring into the sky with Han Li, Jin Tong, and Little White. In the blink of an eye, they were in the layers of clouds tens of thousands of feet high, but they did not stop, continuing to rise.

The Heaven and Earth Spiritual Energy in the surrounding space rapidly thinned, and the sky gradually became clearer.

"Hold on tight," Yue Mian's voice came, and he stretched out his two claws.

Countless cyan magical symbols shot out, transforming into streams of cyan gas that surrounded them.

The cyan giant bird's speed increased a hundredfold, and everything around became blurred instantly.

Han Li's body shook, and he was almost thrown out. He hurriedly circulated his cultivation technique, adhering to the cyan giant bird beneath him.

Everything around changed rapidly. After a moment, with a "whoosh," the cyan giant bird seemed to break through a certain boundary, arriving in a unique space.

All around was a pure, incomparably blue color, without a trace of clouds or dust, yet it exuded an ancient sense of loneliness.

However, there was no trace of Heaven and Earth Spiritual Energy here, nor any other energy. There was only endless nothingness.

Han Li felt a sense of emotion upon seeing this scene.

He had never flown so high before. It turned out that after crossing tens of thousands of feet of clouds, this was the sight.

"Where is this... I don't seem to have been here before," Jin Tong murmured, looking around blankly.

"This is the Azure Underworld Domain," Little White's voice suddenly came from the side.

"Azure Underworld Domain?" Han Li was startled.

"I saw it in my father's memories. There are three major areas in the high altitude of the True Immortal World. This is the Azure Underworld Domain, the closest to the ground. Passing through the Azure Underworld Domain is the Celestial Wind Domain, and beyond that is the legendary Extraterrestrial Domain, also known as the Outer Void," Little White continued.

"Azure Underworld Domain, Celestial Wind Domain, Extraterrestrial Domain..." Han Li murmured.

"These three major areas are all located extremely high and are full of dangers. For example, there is no Heaven and Earth Spiritual Energy in this Azure Underworld Domain. Staying here for a long time will cause considerable harm to a cultivator's body. Ordinary cultivators will not come here, so there are very few records in the classics," Little White said.

Han Li nodded upon hearing this.

In fact, with his cultivation, it would not be difficult for him to come to this Azure Underworld Domain, but he had been busy improving his cultivation over the years, and because he was wanted by the Heavenly Court, he had been hiding everywhere, unable to properly explore the outer space.

Jin Tong frowned slightly, seemingly unaccustomed to the environment of the Azure Underworld Domain.

"Jin Tong, are you alright?" Han Li asked, seeing this.

"I'm fine. We Gold Devouring Immortals devour everything for a living. The lack of Heaven and Earth Spiritual Energy here makes me feel a little uncomfortable," Jin Tong shook his head and said.

"In that case, why don't you go into the Flower Branch Space to rest," Han Li said.

Seeing Jin Tong nod, Han Li waved his hand and took him into the Flower Branch Space.

The cyan giant bird flapped its wings, continuing to fly towards the sky.

The Azure Underworld Domain was astonishingly large. Even at the cyan giant bird's current speed, it took a good half an hour to reach the end.

The void ahead began to vibrate, stirring up bursts of gray-black storms, wave after wave, and emitting extremely harsh whistling sounds.

"Could this be the so-called Celestial Wind Domain?" Han Li's pupils shrank slightly as he murmured.

"Most likely. The Celestial Wind Domain is full of Nine Heavens Astral Winds, which are very dangerous, but compared to the Extraterrestrial Void, this is nothing," Little White said.

Before he could finish speaking, the cyan giant bird had already plunged headfirst into the Nine Heavens Astral Winds without hesitation.

Surrounding them, gray-black storms surged and rolled, emitting deafening roars. Even Han Li felt a sharp pain in his ears, as if they were about to be pierced. He hurriedly circulated the Time Laws to protect his eardrums.

Little White also had a layer of white light rising from his body, protecting his entire body.

The gray-black storm surged like an angry tide, baring its fangs and claws as it attacked the cyan giant bird, but the giant bird's body was now covered in a layer of cyan light, easily blocking the surging Nine Heavens Astral Winds outside. Its speed did not decrease at all as it continued to fly towards the sky.

Han Li was initially a little worried, but seeing that the cyan giant bird was flying extremely steadily, he relaxed and began to observe the surrounding Nine Heavens Astral Winds.

These gray-black storms were completely different from all the wind forces he had seen before, filled with an incomparably violent power that seemed capable of tearing and crushing everything.

Within the gray-black storm, thin black lines could occasionally be seen. Wherever they passed, the void was easily torn open with cracks.

However, those black lines were easily blocked by the cyan light around the cyan giant bird's body.

Little White's eyes suddenly lit up, and he raised his hand and waved.

A white light shot out from his body, revealing a white cloth bag, which was the Natal Immortal Artifact his father had given him.

The bag spun around and suddenly expanded tenfold. A circle of hazy white light appeared at the mouth of the bag, emitting a huge suction force.

The Nine Heavens Astral Winds within a thousand miles immediately shot over like a long whale absorbing water, instantly disappearing into the white cloth bag.

Those thin black lines also entered the white cloth bag along with the surrounding Nine Heavens Astral Winds.

The white cloth bag, having collected these Nine Heavens Astral Winds, did not stop, but continued to fly towards other places, like a heaven-devouring beast, devouring all the Nine Heavens Astral Winds wherever it passed.

"What are you collecting these Nine Heavens Astral Winds for?" Han Li asked.

"What I want is not ordinary Nine Heavens Astral Winds, but those thin black lines. That is Black Aeolus Wind, something that is born after tens of millions of years of Nine Heavens Astral Wind's power condensing. Seeing these Black Aeolus Winds reminded me that my father's memories contain a secret technique to refine a kind of Wind Breaking Bead with those Black Aeolus Winds. It's extremely powerful, and even Great Luo cultivators can't handle it. It's rare to come to this Celestial Wind Domain, so I'll take the opportunity to collect some and try refining it," Little White said with a smile, then pinched a magical symbol to urge the white bag, continuously collecting those Black Aeolus Winds.

Han Li nodded slightly, his gaze turning towards the white cloth bag, a strange color flashing in his eyes.

When Little White had just offered this item, he had subconsciously released a trace of Divine Sense to probe it, but it had been swallowed by the white cloth bag in an instant and annihilated within.

This bag was unremarkable, but it seemed to contain some kind of special power. This was just the result of Little White casually urging it. When truly urged, who knew how much power it could unleash.

As the cyan giant bird flapped its wings and flew, it soon reached the end of the Celestial Wind Domain.

It grabbed forward with its two claws, and a huge space crack appeared. The giant bird swayed and flew into it.

Han Li's vision blurred, and the next moment he appeared in a black space.

Countless meteorites of all sizes floated here, some only the size of houses, others incredibly huge, the edge of which could not be seen with the naked eye. They moved in various irregular patterns, even colliding with each other, emitting bursts of earth-shattering roars.

Some of those huge meteorites were dimly lit, while others emitted various lights, illuminating these black spaces somewhat.

A blue ice crystal storm suddenly swept past from afar, stretching for hundreds of thousands of miles, like an incredibly huge blue wind dragon, exuding a terrifying aura of ice.

Wherever it passed, smaller meteorites were directly frozen and cracked, swept away by the ice crystal storm, and a thick layer of blue ice instantly condensed on the larger meteorites.

As soon as the blue storm passed, a huge purple cloud appeared from nowhere, sweeping past. Purple lightning flashed within the gray clouds, directly blasting those frozen meteorites apart.

Just as the gray clouds passed, a huge black vortex suddenly appeared in the void, spinning rapidly.

Everything near the vortex rolled towards it, being completely swallowed.

However, the black vortex did not appear for too long. It disappeared as quickly as it had appeared.

"Extraterrestrial Void!" Han Li stood up and blurted out.

This black space gave him a sense of boundlessness. His Nine Serenities Devil Eyes could now perceive everything, but he could not see very far here. The power of his Divine Sense was the same, unable to spread as easily as it could on the ground.

Han Li could vaguely feel that there was a force in this space that was a billion times more powerful than the operation of the sun and moon, slowly operating.

"The Extraterrestrial Void is fraught with dangers, but it also contains endless treasures. With your cultivation, you are barely qualified to come here. You can come here more often in the future to train, which will greatly benefit your cultivation progress," the cyan giant bird said.

As it spoke, it continued to flap its wings and fly forward.

This time, the cyan giant bird did not fly upwards, but forward.

"Indeed, there are many treasures here," Little White's body flashed with white light, transforming into a Pixiu form, sniffing fiercely with his nose, and said excitedly.

He once again offered the white bag, opening his mouth and spitting out a ball of white light into it.

The white cloth bag spread out with a whoosh, becoming hundreds of miles in size.

The bag itself became translucent, and the white threads forming the bag became sparse, forming a net-like fishing net.

The cloth bag emitted a wave of devouring power, and those nearby meteorites were swallowed with a whoosh. White light flashed within the bag, and those swallowed meteorites immediately shattered, revealing pieces of colorful rare minerals.

In just a moment, hundreds of precious materials were stored in the bag.

Seeing this scene, Han Li became even more curious about this white cloth bag.

"Friend Han, although your cultivation is not low, you do not know much about the Dao Ancestors. The power of the Dao Ancestors far exceeds your imagination. Flying below, you are likely to be sensed by other Dao Ancestors. It is safer to come to this Extraterrestrial Void," the cyan giant bird said.

"I see," Han Li said, his eyes flashing as he nodded.

The cyan giant bird flapped its wings and flew forward, and everything around retreated quickly.

The giant bird did not change direction at all, flying straight forward, and ripples of cyan light rippled around its body.

These cyan ripples seemed ordinary, but the power they contained was terrifying. No matter how large the meteorite in front of it was, it would evaporate and disappear as soon as it touched it, without even slowing down the cyan giant bird's flight speed.

Those ice and snow storms, thunderclouds, black holes, and so on were even less of a match. They would disintegrate as soon as they touched its body, leaving not a trace behind.

Han Li was once again shocked by the cyan giant bird's supernatural powers.

He had seen the supernatural powers of the True Spirit King more than once. This kind of existence, equivalent to a Dao Ancestor level expert, could overturn an Immortal Domain with a wave of his hand. Today, such a close and personal experience made him feel the abyss-like gap even more.
