This Isn't a Simple Mutation-It's "Reversion to the Ancestor"!

Lin Xia's gaze returned to Dugu Yan, a hint of understanding in her eyes.

"Dugu Yan inherited this latent bloodline. Under normal circumstances, this bloodline would remain dormant forever, at most making it easier to cultivate 'Medusa's Gaze.' But this time... the fortune of the Ice and Fire Yin Yang Well gave it the key to awaken!"

"First, there's the Nether Jade Phosphorous Skull!"

Lin Xia reviewed the events in her mind.

"This Toxic Immortal Herb is the essence of an extremely yin and poisonous place. The 'poison' it contains is extremely domineering, and its level even surpasses that of the Jade Phosphorous Serpent."

"It Sheer Force attacked and ignited Dugu Yan's Martial Soul Origin, attempting to assimilate it and elevate it to a higher level of Poison-type."

"This process is essentially tracing the foundation of her Martial Soul back to an older and more powerful source of Poison-type!"

"Secondly, it's my blood..."

Lin Xia felt a dull ache from the wound on her arm that hadn't fully healed, her expression complex.

"The essence of the Ice and Fire Dragon Kings, combined with the life essence of many creations that I have fused with."

"This power not only saved her life at the critical moment and Sheer Force and calmed the ferocity of the Immortal Herb, but more importantly... its 'divinity' and 'creative' power provided the perfect 'catalyst' and 'manifestation agent' for that hidden, extremely rare Medusa bloodline!"

"The domineering 'origin-tracing' of the Toxic Immortal Herb is like a raging fire burning away impurities, forcing the Martial Soul form to transform and return towards the direction of the more ancient and powerful 'King of Poison'."

"And my Divine Blood, like the most exquisite carving knife and the most magical nourishment, precisely captured, nurtured, and infinitely amplified the signal of that latent bloodline, catalyzing the possibility of 'atavism' from one in a billion to a reality!"

With this in mind, Lin Xia's last bit of doubt dissipated, replaced by a deeper understanding of the laws governing this world.

"As for why Medusa's bloodline exists on the Douluo Continent? Heh..."

A relieved smile appeared on Lin Xia's lips. This smile affected his internal organs, causing him to cough slightly. This made Bibi Dong immediately tighten her arms and channel a gentle and mellow Soul Power into his body.

Lin Xia glanced gratefully at her master and continued to deduce in her mind.

"What's so strange about that? Douluo Continent itself is a vast world that encompasses countless possibilities! Don't forget the 'Ten Headed Fierce Yang Serpent' coiled beneath the Blood River in the Slaughter City!"

"That's a genuine primordial bloodline! Its very existence proves that in the hidden corners of this continent, in those forgotten ancient ruins or alternate dimensions, there exist powerful lineages of beings that transcend the current understanding of the Soul Beast system, originating from even more ancient eras or other dimensions!"

"If a Ten Headed Fierce Yang Serpent with primordial bloodline can exist in the Slaughter City, then what's impossible about the existence of a strange serpent with a faint Medusa bloodline in some remote, desolate place, or some lost little world, and the transmission of its bloodline through Spirit Bone or some extremely obscure method?"

"The history of the Douluo Continent is vast and boundless, and its hidden secrets far exceed what the world knows!"

"To agonize over whether the appearance of a Medusa Martial Soul is 'reasonable' is to use a mundane framework to measure a world full of miracles!"

Lin Xia made up her mind.

"This isn't a simple mutation, it's 'atavism'!"

"It is the ultimate leap completed by the extremely rare yet incredibly ancient and noble 'mythical bloodline' within Dugu Yan's body, which was ignited by the Nether Jade Phosphorous Skull, nourished and catalyzed by Divine Blood, and originated from the Head Spirit Bone of Dugu Bo, in a desperate situation!"

"Her Martial Soul is no longer the Jade Phosphorous Serpent, but something closer to the source of her bloodline—the true 'Medusa'!"

Lin Xia's gaze became deep and bright again. Although her face was still pale, that confident and composed demeanor had returned.

He looked at Dugu Yan was still adapting to her new body, her eyes filled with both confusion and strength, and then at Dugu Bo was so excited he could hardly contain himself.

"Senior Dugu's Spirit Bone is probably far more precious than he himself imagined. It's not only a powerful skill, but also a key to unlocking the potential of a 'divine-level Martial Soul '!"

"But the key's lock is hidden deep within the bloodline, requiring a miraculous opportunity to turn. And Sister Yanyan just happened to be that 'chosen one.'"

"The road ahead..."

Lin Xia silently made plans in her mind.

"The potential of the Medusa Martial Soul is no less than that of any top-tier Martial Soul, and it even has unique advantages in control and destruction. Combined with her Right Arm Soul Bone, which is the 'poison core,' and Dugu Bo's dedicated teaching... given time, Dugu Yan will surely become an extremely powerful trump card for the Spirit Hall!"

"A Medusa queen with a petrifying gaze and control over all poisons... that's intimidating..."

The Morning Sun in the valley seemed brighter, dispelling the last trace of the night's chill.

Under the unconscious pressure emanating from Medusa, the rising mist from the Ice and Fire Yin Yang Well slowly condensed into miniature purple snake shadows, which then quietly dissipated.

The echoes of Dugu Bo's vow seemed to still reverberate in the valley, mingling with the tinkling of the spring water.

Lin Xia let out a soft breath, a sigh of exhaustion mixed with a sense of satisfaction and anticipation, as if she had personally set the wheels of fate in motion.

Lin Xia knew that Dugu Yan's evolution was not only the birth of a powerful combat force, but also opened a window for him to uncover the more magnificent and ancient bloodline landscape hidden in the Douluo Continent.

The world's waters run deeper than he imagined, and the future he could leverage seemed to have become even broader.

Lin Xia adjusted her posture slightly, nestling deeper into her master's reassuring embrace, feeling that silent protection. She slowly closed her eyes and began to focus all her energy on restoring her depleted essence.

Time flows on in silence.

Lin Xia closed her eyes and regulated her breathing, guiding the red and blue primordial power within her body to flow slowly through her meridians, like a gentle stream nourishing parched land.

Ivysaur lay quietly at his feet, its Four-Colored Light Wheel slowly rotating, absorbing the pure energy dissipating from the valley, especially the trace of poisonous essence contained under Medusa's oppressive power that made it both close and wary. The luster of its scales became increasingly deep and restrained.

After an unknown amount of time, when Lin Xia opened her eyes again, the light in her eyes had mostly returned. Although the emptiness caused by the depletion of her essence was still there, she could move around without much difficulty.

Lin Xia moved slightly, indicating to Bibi Dong that she could sit up.

Bibi Dong carefully released her arm, her purple eyes fixed on him, and asked in a low voice:

"How are you feeling? Is there anything else that's bothering you?"

Her voice carried a barely Frisk tension, as if she were afraid that Lin Xia might make the slightest mistake.

"Don't worry, Master, I'm fine now. I'll recover after a few more days of rest."

Lin Xia smiled slightly and gave Bibi Dong a reassuring look.

Lin Xia stood up and stretched her limbs. She heard a slight sound, like the rubbing of metal against metal, as her body adapted to the Adaptability.
