The ghost realm is complete and leaves

At the temple, only Zhou Yuan and Rain Butterfly remained, everyone else had already left.

Now that they didn't have to worry about the black mist, there was nothing to worry about regarding their safety.

Rain Butterfly sat cross-legged in front of a statue, silently reciting the yin yang mirror in her heart as instructed by her Revered Master.

As Rain Butterfly silently recited, a mirror tens of thousands of miles away emerged from the void, with countless runes flowing within it.

The mirror seemed to sense something, suddenly bursting forth with a brilliant light, directly tearing open the void and heading straight for the temple.

Zhou Yuan sat cross-legged beside Xin Yudie, closing his eyes to rest, but his Divine Soul covered an area of a thousand miles.

He had fused with the Ghost Domain's karmic Origin, and at this moment, he was like the Lord of Heaven and Earth to the Ghost Domain.

By evening, the heavy rain had stopped, the dark clouds in the sky had dispersed, revealing a clear blue sky, with white clouds drifting in the air.

Just then, a golden sun was setting in the west, and golden evening glow filled the sky.

It was as if the rain had cleared, and the sky was full of rosy clouds, seemingly celebrating the rebirth of the Ghost Domain.

Just then, Zhou Yuan opened his eyes and looked at the distant sky.

A mirror, like a streak of light, cut through the sky, instantly appearing above the temple; it was precisely the yin yang mirror.

From Zhou Yuan's glabella, the Creation Starry Sky Cauldron automatically appeared, then floated above Zhou Yuan's head, the cauldron humming and vibrating.

Zhou Yuan didn't move, just quietly watching the yin yang mirror in the sky.

The yin yang mirror flew down from the sky, circled Xin Yudie once, and then a beam of light emerged from the yin yang mirror, shining on Xin Yudie's glabella.

On Xin Yudie's glabella, a mirror pattern emerged.

This mirror pattern was half black and half white, extremely mysterious, with Yin and Yang energies flowing within it.

Xin Yudie looked at the yin yang mirror with joy in her eyes, and as she reached out her hand, the yin yang mirror automatically descended into her palm!

Xin Yudie's eyes lit up; she finally realized that she could touch this mirror.

The yin yang mirror and Xin Yudie ran around the temple square, like two playful young children.

Xin Yudie giggled, exceptionally happy.

The Yin and Yang energies within her body were stirred, and unknowingly, her cultivation continuously broke through, reaching the Golden Core Realm Peak.

By night, Xin Yudie was perhaps tired, holding the yin yang mirror in her hands, she leaned against Zhou Yuan and fell into a deep sleep.

After she fell asleep, the yin yang mirror flew up, circled the Creation Starry Sky Cauldron once, then slowly descended into the cauldron, perfectly settling into the groove!

As the yin yang mirror fell, endless runes erupted from the Creation Starry Sky Cauldron.

The star patterns on it continuously lit up, and these runes flew out from the cauldron, constantly imprinting themselves on Zhou Yuan, with some also falling on Xin Yudie.

In Zhou Yuan's Divine Soul Sea of Consciousness, a special cultivation method appeared: the "Heaven and Earth Yin Yang Creation Art"!

But Zhou Yuan only glanced at it and was immediately dumbfounded; this cultivation method required a minimum of half-Saint to Cultivate!

He didn't know how many layers this cultivation method had, but his current cultivation was insufficient, unable to even manifest the first layer.

However, Zhou Yuan was not discouraged; his eyes, instead, were brighter than ever before.

With the integration of the yin yang mirror and the complete perfection of the Creation Starry Sky Cauldron, Zhou Yuan seemed to gain countless insights into the Ghost Domain.

These insights were not his, but those of the yin yang mirror.

The yin yang mirror had been in the Ghost Domain for thousands of years, understanding every blade of grass and every tree there.

Through the yin yang mirror, Zhou Yuan finally understood why the Ghost Domain, also known as the Yin-Yang Domain, had formed.

During the day, the yin yang mirror was Yang-attributed, devouring all spiritual energy.

At night, it was Yin-attributed, releasing Yin energy, which was the black mist; at the same time, the black mist contained the spiritual energy evolved from the yin yang mirror.

However, these black mists also possessed terrifying devouring and corrosive energy, an energy that ordinary people simply couldn't contend with!

Because of this, the Yin-Yang Domain gradually evolved, transforming into the Ghost Domain.

And because a self-contained world existed within the yin yang mirror, a special barrier gradually formed in the Ghost Domain.

Even if Zhou Yuan held the saint ranking and became the Child of Destiny, this barrier remained unshakeable and unaffected by the Xuantian Star Region.

Only when the yin yang mirror completely left the Ghost Domain would this barrier slowly dissipate, finally allowing the Ghost Domain to reappear in the world.

Through the memories of the yin yang mirror, Zhou Yuan saw a special place, where there was a natural void passage leading to an unknown place.

He was greatly surprised, recalling the information obtained from the Wang family and the Ghost Witch Clan, that the Ghost Domain had passages to other planes.

He had always been skeptical about this, but now he finally believed it.

Normally, having fused with the Ghost Domain's karmic Origin, he should have been able to perceive all of this.

However, due to the yin yang mirror's special Seal here, Zhou Yuan was unable to perceive it.

Zhou Yuan had an urge to go and see, but he forcibly restrained himself.

If he were to leave from there and not arrive at the Great Qian Immortal Domain, then it would be over.

The current Xuantian Star Region needed him; he couldn't leave, otherwise everyone remaining here would be in mortal danger.

Most importantly, he wanted to unify the entire Xuantian Star Region, to obtain the Star Region's Origin of the Xuantian Star Region, thereby achieving the position of Saint King.

Zhou Yuan secretly kept that place in mind, feeling that one day in the future, he might need it.

He continued to browse the yin yang mirror's memories, seeing many things about the Ghost Domain, and finally gained a clear understanding of it.

Just then, the sky above the temple suddenly rumbled, and a void passage appeared in the sky.

Above the passage, countless ghostly phantoms emerged; this was the Ten Thousand Ghosts Cave, also the passage to leave the Ghost Domain, with its exit in the Barren Ancient Life Forbidden Zone!

Zhou Yuan was awakened by this rumbling sound, and upon seeing this passage, he was overjoyed; he hadn't expected the Ten Thousand Ghosts Cave to appear before him like this.

His Divine Soul expanded, spreading across the entire Ghost Domain.

His Divine Soul swept through every corner of the Ghost Domain, and soon found Mu Tianji, Qin Yuanfeng, Xuan Chengzi, and others.

In truth, he originally didn't need to send them out, but he didn't want them to know about the yin yang mirror and the Creation Starry Sky Cauldron.

He used this reason to send them away, so he could complete this matter.

He carefully scanned the Ghost Domain with his Divine Soul, and finding no other immortal cultivators' aura, he quickly notified Mu Tianji and the others to return.

Zhou Yuan knew that they should depart.

Zhou Yuan was also worried that this passage would disappear soon, but fortunately, it did not.

Mu Tianji and the others rushed back in the middle of the night. Seeing that everyone had arrived, Zhou Yuan, holding the sleeping Xin Yudie in his arms, stepped into the Ten Thousand Ghosts Cave.

Mu Tianji and the others' eyes lit up, and they followed closely, flying up one after another and entering the Ten Thousand Ghosts Cave.

As their figures disappeared, the Ten Thousand Ghosts Cave slowly dissipated.

The rules of the Ghost Domain began to change, almost daily, with spiritual energy becoming increasingly abundant, and the environment no longer the same as before.

In a few decades at most, the Ghost Domain would fully appear in the Xuantian Star Region, merging with it!

At that time, it would no longer be the Ghost Domain, but the Yin-Yang Domain!
