In the memories of the shadow demon, Xu Chuan saw the lord of the demon realm, a great demon who had reached the peak of the Samsara Realm.
These demons in the Samsara Realm were the guard squad of that demon.
They had come out to investigate the anomaly that had appeared here before.
If any supreme treasure appeared, they were to bring it back at all costs.
If it was a human, they were to kill them on the spot.
Upon arriving here, they had been hiding in the shadows, hoping to benefit after Xu Chuan and the other nine had fought each other to a standstill.
This way, they could not only kill a human but also obtain a supreme treasure.
However, they never expected that Xu Chuan, who did not even possess the cultivation of the Samsara Realm, could fight nine against one, and even in the final blow, he had killed all of their demon squad.
Only a few of them, the shadow demons, had survived.
"Heh, a well-thought-out plan."
Xu Chuan couldn't help but chuckle.
These demons were indeed foolish in the demon realm.
They possessed the cultivation of the Samsara Realm, but lacked any practical combat experience, making them mere paper tigers.
A normal martial artist in the Samsara Realm would have likely detected Xu Chuan's blade domain as soon as it manifested, and would not have waited until Xu Chuan's strike fell before reacting.
Xu Chuan's blade domain had enveloped everyone present from the very beginning.
Including these demons.
He had no intention of letting any of them go.
"Spare me, Lord... spare me..."
As expected of a demon in the Samsara Realm, after having its soul searched by Xu Chuan, this demon did not immediately die. Its spirit was somewhat disordered, and its aura was weak, but it had managed to survive.
It began to beg Xu Chuan for mercy.
However, Xu Chuan merely squeezed its neck with great force, breaking it and silencing it forever.
He casually tossed the corpse aside.
Demons were not worth any sympathy.
Seeing Xu Chuan's decisive killing, the other shadow demons trembled in fear, dreading that they would be the next to have their souls searched by Xu Chuan.
Xu Chuan did not keep them waiting for long.
After fully digesting the memories of this shadow demon, Xu Chuan proceeded to search the souls of the remaining shadow demons one by one, and then kill them.
After reading all the memories of the shadow demons, Xu Chuan finally understood what the lord of the demon realm intended to do.
The memories revealed a legend circulating in the demon realm.
Deep beneath the demon realm, a special demon was sealed, imprisoned since the war between humans and demons.
And their existence as demons was meant to nourish this sealed demon.
The entire demon realm was constructed for this demon.
This demon was exceptionally unique. As long as it was supplied with demonic energy, it was immortal and could regenerate no matter how many times it was killed.
However, its regeneration had a special condition: it required a physical body with a cultivation level of at least the Samsara Realm.
Only then could it regenerate through a host body.
This was also why the great formation in the ancient battlefield restricted all humans and demons to cultivation levels below the Heaven-Piercing Realm.
This demon possessed the cultivation of the Emperor Realm. It had been killed countless times by human Emperors in the past, yet they could not truly destroy it.
Within a very short period, it would regenerate through a host body and quickly return to its peak strength.
Unable to do anything else, they finally sealed it, hoping that time would wear it down.
The powerful demons of the demon race eventually found the location of the seal. However, due to the continuous defeats of the demon race, they had to retreat before they could rescue it.
Helpless, they used an extremely covert method to establish a demon realm on the seal, placing some low-level demons within it to nourish this sealed demon.
"So that's how the demon realm came to be."
Xu Chuan mused, tapping his chin thoughtfully.
As for why the lord of the demon realm had driven all the demons out of the demon realm, Xu Chuan also found the answer in their memories.
After hundreds of years of exploration, the lord of the demon realm had finally entered the sealed land of that demon. He did not know what kind of deal he had made with that demon.
Upon emerging, he had been trying to find ways to revive that demon.
After trying numerous methods without success, the lord of the demon realm conceived a plan: he would break through to the Heaven-Piercing Realm himself!
As a demon who had reached the pinnacle of the Samsara Realm, he would have already entered the Heaven-Piercing Realm, or even the Heavenly King Realm, if not for the restrictions of the ancient battlefield.
The only way for him to break through to the Heaven-Piercing Realm in this ancient battlefield was to find a demonic weapon that the demon race had lost in the ancient battlefield. With it, he could ignore the restrictions and break through to the Heaven-Piercing Realm.
This was why he had dispatched all the demons to search for anything they deemed special, and to bring it to him in exchange for rewards.
The large-scale appearance of demons naturally drew the attention of Ning Cangtian, which led to Xu Chuan and his companions entering the ancient battlefield to investigate.
There was a connection in every action and reaction.
"If this special demon is revived, the Eastern Region is likely to face a great calamity."
Xu Chuan pondered the consequences of this event in his heart.
A demon of the Emperor Realm, even if newly resurrected, would still possess terrifying power.
In the current Eastern Region, where there were no Emperors, it would be incredibly difficult to deal with.
Furthermore, if this demon were to reopen the rift to the demon world, it could potentially reignite the war between humans and demons!
"This must absolutely not happen!"
Fierce light shot out from Xu Chuan's eyes.
His current cultivation was not even at the Samsara Realm. If the war between humans and demons broke out, he would be no different from cannon fodder.
It could be said that at that time, anyone without the cultivation of the Heaven-Piercing Realm would be doomed.
He had to stop it!
...
Meanwhile, in a dark hall within the demon realm.
The lord of the demon realm looked at the token that recorded the vital blood of his subordinates, which had shattered. He knew that the entire squad of Samsara Realm guards he had dispatched had perished.
His expression was grim.
As a top-tier demon in the demon realm, every loss of a Samsara Realm demon was significant, and even he, as the lord of the demon realm, could not afford such heavy losses.
"Guards!"
He summoned a demon at the ninth level of the Samsara Realm.
"My Lord, what is your command?"
The demon who entered knelt on one knee and asked respectfully.
Among demons, hierarchy and status were clearly defined. One had to show respect to those stronger than themselves.
"Take a squad with you and the supreme treasure of our demon realm. Go and investigate who killed the others. You must bring that person back to me. I will make them suffer a fate worse than death!"
The demon lord commanded.
"Your subordinate obeys!"
With a wave of his hand, the demon lord dismissed the demon, and the entire hall once again fell into darkness.
Then, the demon lord opened a hidden door, revealing a staircase descending vertically. He slowly walked down the stairs.
At the end of the staircase.
He saw a giant blood pool, within which a head formed of blood was bound by several dark chains, unable to move an inch.
"Ancestral Demon Lord."
Upon entering, the lord of the demon realm first bowed respectfully.
"Have you found it yet?"
A chilling voice emanated from the head.
"Not yet, but your subordinate is making every effort to find it."
Hearing this voice, the lord of the demon realm could not help but tremble slightly, and then replied respectfully.
"Then why have you come?"
The voice was devoid of any emotion.
"My actions of dispatching all the demons have attracted outside attention. Humans have already entered to investigate. I fear..."
"Fear what? With me here, as long as I can be reborn, nothing else is a problem!"
The lord of the demon realm's words were interrupted by the voice.
"Yes, your subordinate will take his leave."
Without further conversation, he slowly retreated from the place.
