Vile Evil Hides Under The Veil

As Eren transitioned between different elemental environments within the isolation barrier, the very air around him shifted.

With each change, his appearance mirrored the elemental forces at play.

Sweating profusely amidst a fiery landscape, he summoned flames through practiced Mantras and Mudras. The flickering fire cast an ethereal glow, reflecting his immersion in the infernal hell he had created for himself.

In a swift shift, the temperature plummeted, and a cold frost enveloped the surroundings. Eren's breath materialized in the frigid air as he executed precise Asanas, channeling the frosty essence through the corresponding Mudras. His skin, once glistening with sweat, now bore the telltale signs of a chilling frostbite.

Even Eren's A-Ranked physique bore the toll of Rootless Tantra practice.

The intentional use of specific Mantras, Mudras, and Asanas, orchestrated in a harmonious blend, was making his body go through constant phases of destruction and reconstruction.

Each precise movement synergized with the effects of the Rootless Tantra, subjecting him to the physical strain of the practice.

[ Bloodline Skill: Expedited Regeneration ]

While Eren's inherent bloodline abilities facilitated rapid healing, mending burnt or ruptured skin with a mere snap of his fingers, the expedited regeneration only contributed to a cycle of enduring misery.

The swift repair of injuries served as a prelude to the inevitability of subjecting himself to fresh wounds in the subsequent iterations of the Tantra practice.

"One… One more time."

The butcher said to himself in short breaths. He was practicing the Rootless Tantra naked and one could see his chiseled body covered in blood, sweat, and fleshly impurities. He didn't know how much time had passed. But he didn't care. He started the process all over again, this time with even more ferocity than before.

With the fluidity of a seasoned practitioner, Eren transmuted the environment again. A scorching desert emerged, and beads of perspiration dripped from his brow as he invoked the scalding power. The intensity of the desert sun seemed to bear down on him, a testament to the mental and physical toll exacted by the Rootless Tantra.

[ Spirit: 99 ]

[ Warning: Excessive consumption of Spirit Stat has been observed. The user will lose consciousness if and when the value reaches zero. ]

[ Alert: User's Tantra practice observed to impact all Stats. Prolonged continuation may result in severe physical exhaustion. ]

As the cycle continued, Eren's body and mind exhibited signs of fatigue and resilience. Dry skin, weariness etched on his face, and yet, an unwavering determination fueled his every movement.

Eren systematically strengthened his Elemental Affinity for each element. Although his proficiency in the water element had already reached its zenith due to his divine connection, he diligently engaged in performing Mudras, Asanas, and Mantras associated with the water element. He aimed to maintain a harmonious balance in his Tantra practice.

The roots of his connection to various elements deepened with each iteration, making him a conduit for the very forces he sought to master.

"Hm? What... why are you here?"

Eren halted his Tantra Practice upon noticing Roza Thaglas standing outside the isolation barrier, patiently awaiting his attention. He took a deep breath before rising from his position.

Stretching his limbs, Eren reached into his Inventory and summoned a precious vial of potion. With a swift uncorking, he downed the contents of the vial in one gulp, then dispelled the isolation barrier with a snap of his fingers.

In a matter of moments, the majority of Eren's physical and mental fatigue dissipated into thin air. Enveloped in a cloud of fire, he burned away impurities, followed by the appearance of a mass of water-element mana that cleansed him, leaving behind a refreshed and cleansed body, as if he had just taken a rejuvenating bath.

"My lord, that Wilfer guy wanted to deliver this invitation from the Temple of Sekhmet to you."

Roza respectfully conveyed as she presented the scroll to Eren. Eren approached her, standing within arm's reach. Accepting the scroll, he unsealed it and began reading immediately.

Roza, however, found herself in an awkward predicament. With Eren still unclothed, she grappled with the challenge of where to direct her gaze in such close proximity.

Struggling to maintain decorum, she resisted the temptation to glance downward and observe Eren in his most primal state.

"Hehe," Eren chuckled while perusing the contents of the invitation. "Looks like that useful idiot came through," he mused to himself, silently acknowledging Wilfer's efforts. Just as he was about to address Roza, he noticed her discreetly looking.

"My face is up here, you know," Eren teased, playfully directing Roza's attention. Her cheeks tinged with a subtle blush, a striking contrast against her fair complexion. Too shy to meet Eren's gaze, she began to apologize, but before she could, Eren enveloped her in his embrace.

"I'm feeling good. Let's do it here," Eren whispered into Roza's ear, inhaling the fragrance of her hair. His arms encircled her, and Roza, feeling a warmth within, began to succumb to the moment.

Beep. Beep. Beep.

Suddenly, just as Eren and Roza were on the brink of deepening their connection, a series of beeps resonated from the center of the underground facility.

The sounds signaled the successful assimilation of one of Eren's test subjects, utilizing Echidna's Placenta as the conduit for merging with his Mana Signatures.

Halting his intimate advances, Eren stepped back from Roza. "Perhaps another time," he remarked before swiftly disappearing from his position.

'These damn experiments. Always at the worst possible time.'

Roza muttered a curse at the unfortunate timing of the experiment's conclusion and sighed. Resolving to follow Eren, she was eager to witness the outcome he had achieved this time.

In the blink of an eye, Eren reappeared at the facility's center, dispelling its dedicated isolation barrier. As he walked through the rows of capsules containing test subjects, he quickly identified the capsule where the assimilation process had been successfully completed.

With a satisfied smile, Eren manipulated the Array Formation beneath the capsule, causing Echidna's Placenta to dissolve into thin air. The long-contained test subject was revealed, freed from its confinement.
