The Demon Realm.
On Dragon Mountain.
A demon dragon, carrying a half-dead black dog, was preparing to skin and butcher it for a meal.
When he first saw the black dog, it was merely a fleeting desire. It was said that dogs of this pure black hue, without any mixed fur, were the most nourishing, capable of tonifying the kidneys and strengthening yang, curing various forms of impotence.
All living beings, from heaven and earth, that could tonify the kidneys were easily coveted, and their fates were seldom good.
At that time, he had intended to casually grab the black dog and take it back to eat.
Who would have thought that although the black dog appeared heavily injured and pitiful on the surface, after a short pursuit, he discovered its extraordinary strength.
Each time the dog found itself in peril, it would unleash divine abilities and methods he had never heard of or seen before.
The further he chased, the more fear gnawed at him. If this dog were not injured, he would surely not be its match.
Thus, an enmity was forged between them. This time, he had to capture the black dog and kill it himself, otherwise, the consequences would be endless.
And so, this demon and dog chased each other across the Demon Realm for several years, until the black dog was utterly exhausted.
He had lost several pieces of flesh to the black dog's bites, but he had also managed to snatch several mouthfuls of fur from the dog. Finally, he captured the black dog alive, achieving ultimate victory.
Xiao Hei was held by its hind legs, just like a dead dog.
He could not comprehend why, ever since accepting his master's mission, he had been plagued by misfortune, and his injuries had never healed.
To think that he, a dignified Earth Immortal, would repeatedly suffer at the hands of mere mortals in the lower realms. The unwillingness in his heart was immense.
Seeing the demon dragon sharpening its blade, ready to deal with him.
Between life and death lay great terror!
Xiao Hei was now enveloped by a mixture of unwillingness and profound fear.
He did not want to die!
He, a dignified immortal dog, certainly did not wish to die a humiliating death at the hands of a mortal from the lower realms.
"Wait a moment, I have an important secret to exchange with you..."
The demon dragon paused for a moment upon hearing this, then raised its sharp knife again, intending to skin it first, to prevent any unforeseen circumstances.
"I have immortal realm secret techniques to exchange with you!"
The demon dragon recalled the various escape techniques the black dog had used previously and was very tempted. He hesitated.
"I have five escape secret techniques. If you learn them, no one in this world will ever be able to capture you again."
Seeing that the demon dragon was somewhat tempted, Xiao Hei continued to persuade and entice.
"You can seal me with restrictions first."
"I only beg to prolong my existence, to keep a small life is enough."
The demon dragon pondered for a while and felt it might be worth a try.
After all, the black dog was in his hands now. If he could capture it the first time, he could capture it the second time. It could not escape his grasp.
To be cautious, he first severed the black dog's four limbs with his blade and then imposed heavy restrictions, ensuring absolute safety.
The black dog let out a few piteous cries, showing no objection to this, and immediately recited a spell.
"I will cultivate it first. If there is any mistake, I will kill you with one blow."
The demon dragon, having obtained the incantation, immediately began to practice it on the spot.
The black dog, restrained with its limbs bleeding, remained in its pathetic state.
But what the demon dragon did not know was that there was a storage space within the black dog.
At this moment, a piece of immortal stone floated up within the storage space, emitting a faint, milky immortal aura, which was absorbed by the black dog's physical body.
Ever since descending to the lower realm, he had not had the opportunity to recover his strength. Now, it was rapidly regaining.
Watching his internal strength rapidly recover and grow stronger, Xiao Hei suppressed his excitement, maintaining a calm exterior.
This time, he was determined to recover more strength, plan meticulously, and then act, to escape this extremely unlucky state.
The demon dragon cultivated according to the incantation given by Xiao Hei, and indeed, there were no errors. In just over ten days, he had initially mastered one secret technique, filling him with joy.
"Good, I have successfully cultivated this secret technique. Now, tell me the next one!"
The demon dragon still held a sharp knife in his hand, and as he spoke, he kept gesturing towards Xiao Hei, giving the impression that he would strike if there was any disagreement.
However, at this very moment, a faint white light emanated from Xiao Hei, and a powerful force surged forth.
"Boom!"
This mere leakage of power shattered the furniture in the cave dwelling into pieces. The demon dragon was sent flying back dozens of feet, and the cave dwelling subsequently collapsed completely!
The demon dragon looked at everything before him with disbelief. What kind of formidable being had he captured?
Judging by this power, this black dog might be a legendary Mahayana realm expert.
But he could never have imagined that he had once captured an immortal dog and almost eaten its flesh.
Such a being was too far removed from him.
Immortal energy circulated within Xiao Hei. His severed limbs flew back and reattached themselves to his feet, and his injuries healed instantly.
Xiao Hei revealed his true form, his body growing to the size of Dragon Mountain itself, exuding immense might.
"No... impossible! I had sealed your entire body, you shouldn't be able to wield any magic!"
The demon dragon, suppressed to the ground by a powerful aura, still found it difficult to accept the sudden turn of events.
"Because I am not using magic!"
As Xiao Hei spoke, he swiped with his claw. The demon dragon was crushed into a bloody pulp, its soul annihilated, utterly dead.
On Dragon Mountain, this sudden surge of powerful energy had already alerted the demon dragon clan experts on the mountain.
"How dare you fiend! To dare to run rampant on my Dragon Mountain!"
"Fiend, die!"
A dog daring to exude such powerful energy on their sacred mountain was almost an insult to their faces, a direct affront to the Demon Dragon Clan.
How could they, who had always held themselves in high regard, tolerate this?
The experts of the Demon Dragon Clan appeared in unison, vowing to slay this wild dog that dared to provoke them.
"Rumble... rumble..."
"Ahhh... my waist is broken!"
"Ahhh... my head is gone!"
"Woof woof woof... my tail!"
On this day, the battle on Dragon Mountain was extremely fierce, with constant rumbling sounds.
Even a large section of Dragon Mountain was shaved off by the great divine abilities.
The Demon Dragon Clan had suppressed this realm for countless years, possessing deep foundations and countless strong individuals. Even now, with all their techniques unleashed, they suffered heavy casualties.
But even so, the Demon Dragon Clan had no retreat. They could only grit their teeth and persevere.
For this was their territory. Losing this battle meant losing the entire world.
At the same time, Xiao Hei was also not having an easy time. Although he had recovered some of his strength, this was, after all, the lower realm, and he could not unleash his full power.
Furthermore, there was only demonic energy here. He could not absorb immortal energy to replenish himself during combat, greatly limiting his strength. Now, it was good if he could exert one or two tenths of his power.
Therefore, although Xiao Hei appeared to have gained an overwhelming advantage, in reality, he was also suffering. Many ants could still bite an elephant to death, and he had sustained many injuries.
"Hahaha... Grandpa Hei is leaving..."
Xiao Hei felt that the recently recovered immortal power had been significantly depleted. If he continued to drain it, he might lose again. He let out a wild laugh, transformed into a gust of wind, and flew away.
