Immortal through Beast Taming

This voice, very childish, doesn't sound like an elder, but rather like a child.

When it reached the ears of the Divine Pine, it made him pause.

"Child Immortal?"

When the ancestor of the Yin Corpse Sect was trapped within the heavenly tribulation, a boy in yellow clothes, not more than ten years old, appeared in the void.

The Divine Pine originally focused entirely on the heavenly tribulation and the Void Profound Yin Spirit, but after this boy stepped out, he couldn't help but be amazed.

"Though I expected someone from the Demon Extermination Bureau to come, I didn't expect such a big figure to appear."

"A big figure... In comparison, the fact that you as a plant spirit have cultivated to such a level is even more terrifying." The boy said with a cheerful smile.

"I've heard that thousands of years ago, Mist Forest had a 'force' entirely composed of plant spirits, but a traitor emerged from that force, slaughtered all his kin, and then hid in the Ancient Country."

"That demon plant who exterminated the group of plant spirits, that was you, wasn't it?"

The Divine Pine chuckled and replied, "As expected of one of the directors of the Demon Extermination Bureau, you figured out my background so quickly."

"But rest assured, I'm not some dangerous element. Back then, I was naive and thought I had found a home, not realizing I had wandered into a 'demon plant force'. To protect myself, I had no choice but to eliminate them all."

"I've been keeping to myself in the Ancient Country all these years, haven't I?"

"Indeed, you've kept to yourself for many years, but who would have thought the Sect Management Office would issue an order that released you." The boy said, "You can stay in the Ancient Country without any issue, but as for this cultivator from the Yin Corpse Sect, we of the Demon Extermination Bureau are taking him."

Boom.

Just barely surviving the heavenly tribulation, the Void Profound Yin Spirit, hadn't yet reacted before he, along with the Void Profound Phenomenon 'Black Coffin', was pulled into the Immortal Prison cast by the boy.

Seeing this, the Divine Pine immediately revealed his true form; a giant tree appeared with a black face on it, glaring ominously at this strong figure from the Demon Extermination Bureau.

The boy laughed, "Don't worry, I won't make you work for free. Using the power of the heavenly tribulation to weaken him is indeed the easiest and most efficient method, otherwise I'd have to face all his various strange techniques directly."

"To express the gratitude of the Demon Extermination Bureau, how about I take you as a foster son?"

"Get lost, old man! I'm not younger than you." Mo Song shouted angrily, "I've long heard that one director from the Demon Extermination Bureau practices the Child Immortal Technique, making his body permanently fixed in child appearance, resulting in no descendants, hence he likes taking people as foster sons."

"But I have no interest in becoming your foster son."

The boy regretfully shook his head and said, "Such a pity, I've taken humans as foster sons and demon beasts as foster sons, but I've yet to take a plant spirit."

"No problem, this fellow doesn't have much use for you. His magical tools, after a battle with a strong figure of the Ancient Country, were almost completely destroyed, and aside from his memories, he no longer has anything worthwhile."

"But his memories, for you, are not so easily explored. Better to leave it to us, the Demon Extermination Bureau, to maximize its value."

"Enough with the nonsense! I don't care about anything else, but if I'm not satisfied, even if you are of the Void Profound Realm, old man won't let it go easily."

"I am curious about what kind of hidden cards you have; I can sense you're not bluffing, but I also sense you don't want to go that far." The boy showed a puzzled expression.

"Forget it, young man, come out here." The boy suddenly shouted towards the cold pool, and soon, astonishing ripples emerged on the cold pool.

Accompanied by water splashing into the sky, a young man with white hair and blue eyes floated up, his aura overwhelmingly terrifying, twelve vortex-like levels of cold air swirling around him, snowflakes began to fall the moment he stepped out.

The boy looked at Lin Jing and said, "Peak of Qi Cultivation level twelve."

"That Ice Soul Gu parasitic within him seems to have successfully established Foundation."

"With the cultivation of Qi level twelve, combined with the Gu Emperor's bloodline's Ice Soul Gu, an ordinary Golden Core wouldn't stand a chance against him."

"Such exceptional talent, only one level behind Prince Gu who has the help of a Realm-Breaking Beast, is this still the Longevity Body I know? It seems the Beast Taming Technique and Longevity Body are the most compatible."

Lin Jing was forcibly pulled from the depths of the cold pool by a formidable force, suddenly looked at the boy, then at the Divine Pine, and exclaimed, "Senior, what's going on!"

"Could he be the one..."

"Look closely, he's a living person, not a Yin Spirit. This person is the old monster from the Demon Extermination Bureau."

"You know about the four demon exterminating families of the bureau, right? Your detective classmate Gao Sheng's maternal grandfather is one of the ancestors of the demon exterminating families."

"And this old monster before you... The Divinity Transformation Ancestor of the four main demon exterminating families, you still should call him foster father."

"Those four demon exterminating families, all were cultivated by him."

"What!?" Lin Jing looked at the yellow-clad boy in shock.

"The cultivator from the Yin Corpse Sect has already been dealt with, but this fellow has taken the Yin Spirit, now negotiating terms." The Divine Pine snorted coldly.

"Indeed, I don't have much to offer you." The boy smiled at the Divine Pine and said, "But since you're his Guardian now, granting him the compensation should be no issue, right?"

Compared to compensating the Divine Pine with resources, enhancing this demon plant's power, the boy preferred to give the compensation to Lin Jing the human.

The Divine Pine was about to scold when the yellow-clad boy took out a jade scroll and said:

"This is the physique cultivation method inherited from the first demon sect of the previous continent, the Celestial Demon Sect. It allows cultivation of an entirely new physique 'Celestial Demon Body' without the limitations of the original physique."

"The Celestial Demon Body can temporarily boost cultivation by expending lifespan."

"According to the records of the Demon Extermination Bureau, when the Celestial Demon Sect was destroyed, a Divinity Transformation Demon Cultivator used the Celestial Demon Body, sacrificed a thousand years of lifespan, directly increasing his combat power to the Void Profound Realm, and remarkably maintained this power for ten years before falling back to Divinity Transformation."

"Although he lost a thousand years of lifespan, he evaded certain death through Void Profound combat power and, during those ten years, utilized greater strength to plunder far and wide, seizing vast resources he couldn't obtain with Divinity Transformation combat power."

"Impossible to say whether he lost or gained."

"I do know, however, that for the Longevity Body, cultivating the Celestial Demon Body is a guaranteed profit, Little Pine Tree, what do you think? After all, burning a few thousand years of lifespan isn't a big deal for the Longevity Body."

"There really is such a Secret Technique!" The Divine Pine had long wanted to find a demonic technique for Lin Jing that exchanges life for power, unexpectedly finding it in the Demon Extermination Bureau!

Though this made sense; the place that collected the most demonic techniques worldwide was indeed the Demon Extermination Bureau.

During the demon exterminating war at the founding of Ancient Country, countless demon sects were wiped out by the Ancient Country across the continent.

"It's acceptable." The Divine Pine grinned; if it were this, it felt it wouldn't be a loss to trade, and then said, "But the Demon Extermination Bureau actually offering a demon sect cultivation technique as a trade."

The boy pointed at Lin Jing and said, "He is, after all, now one of the last two Longevity Bodies in the generation; it would be a shame for him to die young. This Celestial Demon Body cultivation method ensures he has an extra life-saving card, reducing the pressure on you, his Guardian."
