This was a great seal, inscribed with the four characters of Hell's Reincarnation.
Using the great seal allowed not only free passage into and out of this relic space but also the release of the aura of the Boundless Yama King, capable of intimidating opponents and compelling their submission.
Alternatively, it could create illusions of hell, trapping individuals in an inescapable abyss.
This great seal was also a treasure left by the Boundless Yama King for the Hell's Impermanence.
It was considered a divine artifact, but unfortunately, it lacked the surplus power to simultaneously activate two divine artifacts.
Zheng Dong subsequently took the Hell's Reincarnation Seal and the Mourning Stick.
Following this, he attempted to refine the Hell's Reincarnation Seal.
This divine artifact, forged by the Boundless Yama King, was not merely a key to this relic space; Zheng Dong sensed it might be useful elsewhere.
Otherwise, it would have been shaped into a key rather than a great seal.
To master the Hell's Reincarnation Seal, one needed to grasp the power of reincarnation.
This, however, did not pose a challenge for Zheng Dong.
He could utilize the power of reincarnation mastered by Youyou to refine the Hell's Reincarnation Seal.
Nevertheless, it still took several days to master the Hell's Reincarnation Seal.
Subsequently, Zheng Dong activated the Hell's Reincarnation Seal, using the relic space's authority to teleport to the resurrection site of the Boundless Yama King.
The location appeared quite ordinary.
The terrain was flat, situated near a forest, with a winding stream flowing beside it.
Zheng Dong couldn't fathom why the Boundless Yama King had chosen this spot to arrange his resurrection method.
The memories of Hell's Impermanence contained no information regarding this matter.
Furthermore, Hell's Impermanence only knew the location, not the method by which the Boundless Yama King intended to resurrect.
Zheng Dong attempted to locate the Boundless Yama King's arrangements.
However, after searching for a long time, he found nothing.
The place seemed as if no one had ever set foot there, devoid of any human traces, let alone any related barriers or grand formations.
There were, however, numerous extraordinary creatures in the nearby forest, which Zheng Dong scared away.
Zheng Dong frowned and continued his attempts.
Unfortunately, despite trying various methods, there was no response.
Even Little Zi's treasure-hunting skill yielded no discoveries.
Could Hell's Impermanence's memory be flawed?
Zheng Dong felt this was unlikely.
The method must be incorrect.
Given that it was an arrangement by the Boundless Yama King, it was only natural for it to be difficult to detect.
Thus, Zheng Dong took out the Hell's Reincarnation Seal again and used the relic space's authority to search.
But there was no reaction whatsoever.
Finally, Zheng Dong attempted to use the power of reincarnation.
In the mythical era, only the Boundless Yama King mastered the power of reincarnation. Zheng Dong surmised that it might have employed this power to arrange its resurrection method.
As he poured streams of reincarnation power into the ground, there was no change initially.
After more than ten minutes, the ground cracked open, revealing a strange, large door.
Inside the door, red light pulsed, seemingly leading to hell.
Zheng Dong was immediately startled.
He could sense that beyond the door lay an unknown dimensional space.
This dimensional space was relatively small, attached to the relic space.
In essence, it was a part of this relic space.
However, without the power of reincarnation, the entrance to this dimensional space would likely remain undiscovered forever.
Zheng Dong hesitated for a moment before deciding to enter and investigate.
Having come this far, it would be a shame not to see.
Moreover, even if an accident occurred, he could use the Time Corridor to return to the present timeline.
Zheng Dong walked towards the fissure in the ground.
It felt like walking into hell.
The dark door was situated between the cracks, its other side completely obscured.
Curiosity piqued, Zheng Dong stepped inside.
He also heightened his vigilance, ready to leave immediately if anything unexpected happened.
Passing through the door, he entered a not-so-large dimensional space.
Within the dimensional space stood an altar.
The altar was constructed from the skulls of various creatures.
The surroundings were adorned with peculiar formations and barriers.
Zheng Dong scanned the area cautiously, not approaching the altar, but rather checking for any potential dangers.
He discovered that this dimensional space was created by the Boundless Yama King, who had occupied a portion of the relic space and used formations and barriers to fashion a semi-independent realm.
It was not detached from the relic space but could be completely sealed.
Furthermore, due to the existence of the relic space, it was quite safe, preventing its destruction by spatial storms.
With Zheng Dong's current understanding of spatial laws, he could not create such a dimensional space.
At most, he could create a semi-open spatial interlayer.
After understanding the situation of this dimensional space, Zheng Dong's comprehension of spatial laws significantly improved.
With the assistance of Ling'er's power, he could also create dimensional spaces.
However, they would collapse shortly after their creation.
Subsequently, finding no immediate danger, Zheng Dong approached the altar.
He ascended, looking down at the altar.
In the center of the altar lay a crimson coffin.
This coffin had no lid, and within it rested a corpse.
To be precise, it was the body the Boundless Yama King had prepared for himself.
Now, only the soul and consciousness of the Boundless Yama King were needed to attempt its resurrection.
This demonstrated the Boundless Yama King's thorough preparation; no external forces were required, and it could resurrect once the time was right.
However, this was merely one of its backup resurrection methods.
It had prepared many such resurrection methods.
This also made Zheng Dong curious about the method the Boundless Yama King most desired to use for its resurrection.
He enveloped himself in the power of reincarnation and gradually approached the altar, stepping onto it.
The Boundless Yama King's true form was very similar to a human, but it had two crimson horns growing from its head.
These were identical to the horns on the heads of Hell Asuras.
Zheng Dong's first impression was that it might be a Hell Asura.
However, this was merely one of the Boundless Yama King's forms.
The true Boundless Yama King possessed one hundred and eight forms, each of which could manifest in several different ways.
For instance, Ling'er could appear as the Elemental World Tree or as the Dragon Vine Grass.
The Dragon Vine Grass could even manifest solely as grass, without the vine.
Even the Undying Dragon God and the Chaos Divine Phoenix had never seen all of the Boundless Yama King's forms.
Zheng Dong did not pay much attention to this.
He noticed that something seemed to be held within the Boundless Yama King's mouth.
He did not reach out directly to pry it open.
Instead, he had Ling'er release an elemental spirit to attempt to open the Boundless Yama King's mouth.
This was a dark elemental spirit with a totem-level strength.
It extended its hand into the coffin, and nothing unusual happened.
However, as it attempted to pry open the Boundless Yama King's mouth, the moment it touched the Boundless Yama King's body, scorching flames instantly ignited.
Eerie flames enveloped the dark elemental spirit, rapidly burning it to ashes.
The dark elemental spirit vanished before it could even resist.
What kind of flame was this?
Zheng Dong looked at the flames on the dark elemental spirit with confusion.
The color was a vivid crimson, like blood, as if a pool of boiling blood had melted the dark elemental spirit.
While these flames were not as potent as Chaos Divine Fire, they were not to be underestimated.
Zheng Dong then had Ling'er summon a fire elemental spirit with quasi-god level strength.
The fire elemental spirit should have a stronger resistance to flames.
The moment the fire elemental spirit reached out to touch the Boundless Yama King, a surge of black liquid gushed out, instantly engulfing the fire elemental spirit and corroding it, leaving no trace behind.
What kind of liquid was this?
Its corrosive power was so immense.
It was likely that even hard steel would be corroded in an instant.
Thus, retrieving the item from the Boundless Yama King's mouth became somewhat troublesome.
Zheng Dong still dared not touch it directly, instead having Ling'er release various elemental spirits to try.
However, the results were the same; each elemental spirit encountered a power that countered it and was instantly killed.
Zheng Dong frowned.
Perhaps the power of reincarnation could work.
He condensed a clone and had the clone, enveloped in the power of reincarnation, approach the Boundless Yama King's body to attempt to retrieve the item from its mouth.
Under the protection of the reincarnation power, the clone successfully pried open the Boundless Yama King's mouth.
Inside its mouth was a black bead.
This was the Yama Bead, a divine artifact refined by the Boundless Yama King for resurrection. There were one hundred and eight of them, and only one was present here.
This bead could not only store the Boundless Yama King's power but also bore its soul imprint, allowing the Boundless Yama King's soul, wherever it might be, to rapidly transfer to this location.
In other words, as long as the Boundless Yama King willed it, it could come to this space from anywhere and attempt to resurrect.
However, the Boundless Yama King did not resurrect.
The moment Zheng Dong's clone pried open its mouth, it eerily opened its eyes.
This scene was terrifying.
The Boundless Yama King stared intently at Zheng Dong's clone.
Zheng Dong's clone attempted to retreat, but it felt its body becoming uncontrollable.
Subsequently, a strange power surged towards the clone, and through the clone, it flowed towards Zheng Dong.
Zheng Dong was immediately startled.
The Boundless Yama King's power could directly affect him through the clone.
Just as he was about to leave the altar, he found his body also unable to move, completely beyond his control.
"Greedy beast tamer, since you desire my possessions, I shall take your body instead."
The Boundless Yama King was very interested in Zheng Dong's body. It wanted to know how a beast tamer like Zheng Dong had mastered the power of reincarnation.
Of course, this was merely the soul imprint left by the Boundless Yama King within the Yama Bead taking effect.
This imprint was similar to the imprint the Chaos Divine Phoenix had left in the Time Corridor; even if the Boundless Yama King's soul in the outside world was damaged or disappeared, this imprint could, under certain special circumstances, lead to resurrection.
As the Boundless Yama King's power surged into his body, Zheng Dong gradually lost control of his own body.
This was terrifying!
If he lost his body, he would likely be killed by the Boundless Yama King as well.
Fortunately, Zheng Dong's reaction was swift.
He used the Chaos Divine Fire.
The Chaos Divine Fire could burn everything, even the eerie power released by the Boundless Yama King.
While his body was not yet fully controlled by the Boundless Yama King, he quickly used the Chaos Divine Fire to purge the Boundless Yama King's power.
However, he was still shaken and dared not attempt to take the Yama Bead from the Boundless Yama King's mouth again.
The Boundless Yama King, however, was even more astonished.
It had not expected Zheng Dong to not only master the power of reincarnation but also the Chaos Divine Fire.
"What is your relationship with the Chaos Divine Phoenix?"
Zheng Dong did not explain; he directly summoned the Chaos Divine Phoenix.
The Chaos Divine Phoenix and the Boundless Yama King seemed to have a good relationship. Zheng Dong hoped that, out of respect for the Chaos Divine Phoenix, the Boundless Yama King would allow him to leave safely.
The Boundless Yama King was also surprised to see the Chaos Divine Phoenix's current appearance.
After a moment of stunned silence, it continued:
"The great tribulation is upon us, and no one can escape. Since the Chaos Divine Phoenix has chosen you to help it resurrect, I shall also ask you to do something for me."
Zheng Dong did not refuse. If the Boundless Yama King had a request, he could naturally leave safely.
"In truth, I had no intention of resurrecting. Resurrection would attract my future self, leading to me being killed once more, or even being devoured.
Therefore, I chose reincarnation. Unfortunately, after reincarnation, my memories would be sealed, preventing my awakening.
If I were to awaken, I would surely reclaim all the Yama Beads.
Now, I hope you can awaken the memories of my reincarnated body and help me recover my supreme power," the Boundless Yama King said.
Zheng Dong frowned.
This was not an easy favor to grant!
"Senior, how can I find your reincarnated body?"
"That is simple. Carry the Yama Bead with you, and you will naturally sense it. Once my reincarnated body recovers its memories, I can help you three times!" the Boundless Yama King continued.
With the Boundless Yama King's help, dealing with the person in the black robe would be easier.
Subsequently, Zheng Dong agreed to the Boundless Yama King's request.
The Yama Bead in the Boundless Yama King's mouth flew to Zheng Dong of its own accord.
Zheng Dong, carrying the Yama Bead, left the dimensional space and returned to the relic space.
After a few days of rest, Zheng Dong also used the Hell's Reincarnation Seal to leave the relic space.
However, he did not return to Blue Star but appeared in another world.
This other world had not yet descended and merged with Blue Star.
This meant that Zheng Dong had no idea how to return to Yanhuang.
It would likely take a few more years for the signs of this other world merging with Blue Star to appear.
What should he do?
Should he return to the present timeline and come back again?
Zheng Dong was not confident he could return to this era again.
After some thought, he decided to first understand this other world and search for the Boundless Yama King's reincarnated body.
This other world was vast, equivalent to ten times the size of Blue Star.
The elemental energies here were also more concentrated than on Blue Star.
As a result, it was inhabited by numerous extraordinary creatures, with hundreds of totem kingdoms.
However, there were no humans.
What pleased Zheng Dong the most was the abundance of resources, which could be collected to help the Chaos Divine Phoenix recover its strength quickly and allow Ling'er to condense more elemental spirits.
Thus, Zheng Dong summoned the Chaos Divine Phoenix and tasked it with collecting resources.
They soon arrived at a totem kingdom.
This totem kingdom was dominated by Hellhounds, the strongest among them being the Hell Divine Hound, possessing strength close to that of a Supreme God.
Below the Hell Divine Hound were several Hellhounds with the strength of Upper Gods.
The Hellhound Totem Kingdom was a dominant force in the surrounding region. Their reputation was foul; they not only enjoyed ambushing but were also adept at rear attacks, causing many extraordinary creatures to avoid fighting them.
If they set their sights on someone, their internal organs might be ripped out.
Zheng Dong, however, was unconcerned.
As he entered the Hellhound Totem Kingdom with the Chaos Divine Phoenix, he was targeted by numerous Hellhounds.
Although the Chaos Divine Phoenix flew in the air, many powerful Hellhounds could also fly, and not slowly.
Several totem-level Hellhounds lunged at the Chaos Divine Phoenix.
They not only attacked the Chaos Divine Phoenix but also Zheng Dong, who was beside it.
A Hellhound, taking advantage of Zheng Dong's inattention, lunged at him.
Zheng Dong suddenly felt a tightening in his rear, sensing danger approaching.
Immediately, scorching Chaos Divine Fire surged from his body, burning the attacking Hellhound to ashes.
