OP Sister Chapter 550: Transformation

-----

Jack’s power, previously weakened, surged dramatically in a mere second. His Aura erupted into the skies, resembling a pillar of black and red light.

The more pain someone endures, the stronger they grow through the Seventh Seal of Pain. This was the secret behind the Heavenly Demon’s incredible growth.

Now, Jack overflowed with Demonic Ki and Negative Energy, gathering around him and spreading everywhere.

His Aura surged and enveloped him, transforming him into a shadowy figure with glowing red eyes, resembling a titan with six arms, five heads, dozens of horns, and giant swords of ice and fire.

“W-What?!”

Anna was stunned as she witnessed Jack’s achievement: a complete unity of all seven seals, culminating in a powerful Seven Cursed Seal Manifestation of the Second Stage, imposing enough to intimidate everyone.

Various Constellations observed the titan, some feeling nervous, others wary for reasons unknown, before the titan scattered into black fog and Jack reappeared.

“I feel dizzy...” Jack groaned, clutching his head. “W-What did I just do?”

“You don’t even remember?! You became a three-hundred-meter giant!” Anna said.

“...I did that?!” Jack was surprised.

“Hahaha... my master would be so happy to see someone so talented for the Cursed Seal Arts,” Anna laughed with a soft giggle. “You did something that took me a lot of training!”

“My entire body hurts a lot though... ugh, I can’t move... my energy is depleted...” Jack kept complaining.

“Ah yeah, there was a reason why he forced me to train so much and refine my body through all those trials. It was to forge a body capable of resisting the burden of the seals,” Anna nodded. “But because you didn’t go through the necessary training and gained them instantly, this is what you get, brother. If it had been anybody else, their body would have likely exploded... your body is actually pretty durable! Maybe Fenrir is gone from your body and soul, but the body you strengthened with his help remains.”

“Yeah... I thought about that too,” Jack said, lying on the wooden floor of Buddha’s house. “Ouch... ugh... I’ll meditate for now and gather energy... Anna, what’s next? Do you know some other method I could learn quickly?”

“Hm...” Anna rubbed her chin. “The Heart of Hope Method that Henrietta learned super quickly... maybe you’re compatible? I don’t know, it’s worth a try, right?”

“Heart of Hope... I always have hope, so it shouldn’t be hard to learn,” Jack nodded, as Anna handed him the Manual.

While training for a month with the Constellations, Anna had accomplished several feats.

Thanks to Gilgamesh and Ares’ continuous physical training regimes, Anna had exercised extensively and managed to unleash her body’s power under the pressure and atmosphere of the Great Beyond for prolonged periods.

She had also learned to envelop her entire body with a thin veil of her Radiance at all times. Previously, she could maintain it for only a couple of hours, but now she mastered it to sustain it for a whole day without rest.

This thin veil of Radiance, formed from her Myriad Self Arts, helped her move freely in the atmosphere, even granting the ability to fly briefly and soar when jumping from high altitudes.

At the same time, as she trained and sparred with the two old monsters, her swordsmanship became more refined. She learned to channel more of the “imprinted power” of her skills within her Myriad Self Radiance while her System recovered.

Through this training, she stimulated her body enough for Gram to finally awaken, confused about the situation. Anna had to explain a lengthy summary of everything so far. Now, he slumbered to conserve his energies.

Through constant stimulation of her senses, body, mind, and soul, Anna began to generate silver-colored sparks from her Kronos Heart.

These “Sparks of Time” grew denser, slowly stimulating her Dao Root and the System within her Kronos Heart.

The glitches remained largely unchanged, but Anna could now force her hand through the system window and pierce it with her sword, opening a wound in space to access her Inventory.

It was a crude method, but after extensive training, she could access her Inventory whenever she wanted, though it took effort, which was part of the training.

This wasn’t all she had learned. She mastered manifesting, moving, and spreading her Cosmic Energy within her Cosmic Heart, combining it with her Traits to produce Narrative Attraction Force, capable of bending the laws of physics.

This Narrative Attraction Force manifested in various ways, from basic telekinesis and gravity manipulation to complex applications like manipulating fate and tearing holes in spacetime as a Constellation progressed to higher ranks. Ultimately, a Constellation’s heart could transform into Narrative Attraction Force, and at higher levels, it became a method to twist the world and fate itself.

The Netherworld Emperor likely used his immense Narrative Attraction Force to pull Jack’s soul from here to the Netherworld, a different plane akin to the Dream Plane or the Esper Plane.

It’s a vast power that can affect beings and targets millions of light years away, as the Void King did, tearing through spacetime to enter a parallel timeline. It’s also the primary power Constellations used to interact with entities in lower dimensions.

Anna suffered and nearly went mad facing a Constellation’s true Radiance because its sheer Attraction Force overwrote her existence, burning and disintegrating her as a lesser being.

The “protections” they placed on Anna merely blinded her senses, preventing her from reading their vast stories and going mad or perishing. At this point, she wasn’t sure if she could face them head-on, but with the Myriad Self Radiance Veil, she was not entirely powerless.

She accessed her Inventory only two days ago and was still rummaging through her items, deciding what to use. She offered various materials for the special formation they were building, and Gilgamesh accepted some, including Soul Fragments of Lucifer, Vulcanus, and the Universal Computer.

Thanks to these rich materials Anna possessed, they now needed only a few more to complete the formation realistically.

“I still got a lot of stuff here... But I should share with my brother so he can grow faster. His body needs a boost,” Anna said, rubbing her chin. “Here, brother, take these.”

Anna gave her brother a bottle of Elixir and a small golden pill, a Panacea, which he ate with a red-colored pill she assumed was for healing... a Blood Pill.

“Hm, thank you, Anna. Where did you get these?” he wondered. “They really helped me... ugh?”

Anna’s eyes widened as she realized her grave mistake. Unable to see the items’ descriptions clearly due to her glitched System, she had given her brother a Blood Pill she had stashed for ages!

“Ack! W-What did you give me? Ugh?” he groaned.

Jack’s red eyes grew even redder, his skin paled further, his ears turned pointy, and his fangs sharpened.

“Aahhh! I’m so sorry! Fuck!” Anna screamed. “T-That’s a Blood Pill with the Bloodline of... the Vampire Constellation, Dracula.”

“...! What?!” Jack coughed, his throat sore. “How could you even give me something like... this?!”

“Please drink water!” Anna quickly gave him water, and he felt slightly better, but dizzier and... hungry.

“Ah... I’m a Vampire now? Great... from Werewolf to Vampire... it can’t get any worse...” he sighed, gasping for air.

“I’m so sorry!” Anna said. “I think it can be dispelled with a Bloodline Cleansing Ritual! I’ll get to it right away!”

“Wait...” Jack said. “Give me some... some blood first.”

“B-Blood?!” Anna gasped as her brother hugged her from behind, smelling her neck, his fangs nearly touching her skin. “Eek! J-Jack?!”

She blushed as he acted out of character, his hunger growing. He wouldn’t let go.

He wanted her blood!

“Jack, please wait!” Anna said nervously, as her brother craved a bite.

“I... Ugh...!” he groaned, releasing her and clutching his head.

Anna quickly searched her Inventory for beast blood but then realized something.

“Wait, that’s right! My Immortal Blood is infused with Elements of Lightning, Light, Hope, and so on!” she said, creating a small wound in her palm and pouring her blood into a teacup. “Drink this!”

“Blood...” Jack groaned, drinking it without hesitation. “Gulp, gulp...! Ahhh...! So sweet! What...! What is this- KUGH?!”

FLASH!

Bright light surged from Jack’s body as his Vampire Bloodline was cleansed...

Or rather, it evolved, reacting to Anna’s incredible blood.

“N-No way...!”

Jack’s appearance changed little, but a few strands of white hair appeared in his black hair, and large bat-like wings sprouted from his back.

However, he no longer felt dizzy or craved blood uncontrollably. He was in control of his desires.

And he felt great.

“Anna... I don’t know what you did, but this is incredible,” he said. “Something within me reacted and... I don’t know how to say it, but I feel great. My body is brimming with vitality now...”

“Really?!” Anna wondered. “Wait...! Let me check you!”

Anna ran to her brother, examining him with her new eyes, created using her Nanomachines, Myriad Self Arts, and Celestial Gestalt Class Ability, infused with the Eye of Nirvana’s power granted by Buddha.

These glowing, rainbow-lit eyes allowed Anna to see through all things. They expanded her field of vision like a domain, eliminating the need to create eyes with her Myriad Self Arts Radiance. Her new eyes were as effective, if not better.

“Wow, your body...! It’s dozens of times tougher, brother,” Anna said. “It seems you can better withstand the Seven Cursed Seals now! Nice!”

“Wait, what? What happened though?” Jack asked. “I ate that pill... then I became... weird. After you gave me your blood... I felt fine again? Wait, what are these wings? Some kind of mutation? Hm...”

“I’m sorry... I accidentally fed you a Blood Pill with Dracula’s Blood,” Anna explained. “I was saving it to combine with other bloodlines, but I didn’t care about it anymore. With my System glitched, I couldn’t discern what it was among the piles I was rummaging through... so I gave it to you.”

“Oh...” Jack finally understood.

“When you drank my blood, its high level, divinity, and immortality caused your lesser vampire bloodline under Dracula’s Family to evolve outside his control,” Anna said. “You... evolved into a Pure Breed Vampire.”

“So I’m still a Vampire?!” he asked.

“Yes... sorry,” Anna sighed. “But it’s not so bad! Pure Breed Vampires can start their own Bloodlines and aren’t tormented by endless thirst or primal instincts like lower ranks. It seems you evolved a new Bloodline of your own...”
