Tian Uguisu entered Hell and stumbled into a vast, white world, enveloped by a thick fog. She tried to release her sensory Chakra, but found that Chakra was swallowed up by the fog as soon as it reached three feet, and even her voice couldn't travel far. "This place is suitable for assassination." She took out a spear from her spatial ring. The spear was engraved with specially made anti-illusion runes, which emitted a faint red light in the fog.
She hadn't walked far when she suddenly kicked something. Looking down, she saw a corpse clad in armor, an ice spike formed from condensed mist protruding from its chest. Tian Uguisu raised an eyebrow. Just as she was about to kick the corpse to the side of the road, it suddenly opened its eyes, its empty eye sockets filled with thin black lines. "Join us... stay here forever..."
Tian Uguisu swiftly severed the corpse's neck with a backhand thrust of her spear. Black mist billowed from the cut, emitting a piercing shriek. "So it was possessed by a Mist Demon." She spat a fireball onto the spear blade, then sprinkled a specially prepared talismanic water from the Ten Family's secret medicine onto it, causing a pale golden flame to ignite. "Let's see how your Auntie Ying breaks this mist."
She moved through the mist, spear in hand, the red light on its blade guiding her like a beacon. Whenever a spirit possessed by the Mist Demon lunged at her, she would slash with her spear, the golden flames instantly burning away the Mist Demon and revealing the Soul Crystal that might be hidden within its body. After half an hour, she had accumulated more than a dozen Soul Crystal in her spatial ring. These crystals could be used to refine Soul Replenishing Pill, and were currently extremely valuable and hard to find in the Shinobi World.
Suddenly, the fog ahead churned violently, and a figure in a white robe emerged from it, his face blurred, but he carried a lantern in his hand, the flame within burning an eerie purple. "Outsider, you have disturbed the peace of the Mist Prison," the white-robed figure's voice seemed to echo from countless voices simultaneously, "Hand over your Soul Crystal, and I may grant you a quicker death."
Tian Uguisu laughed, twirling the spear in her hand. "Come and take it yourself if you dare." She deliberately took out the Soul Crystal from her spatial ring and waved them around; several Soul Crystal rolled out, emitting an alluring light. The white-robed man was indeed attracted, and the moment he reached out to pick them up, Tian Uguisu's spear had already pierced his chest.
The white-robed figure vanished in a cloud of mist, leaving behind a purple lantern. Tian Uguisu picked up the lantern and discovered that the handle was made of " Void Wood," a type of wood that could isolate Space-Time Ninjutsu —exactly the material Tsubasa had been searching for. Just as she put the lantern away, the surrounding mist suddenly began to thin, revealing a stone tablet shrouded in mist in the distance, inscribed with the three large characters " Mist Prison."
"Looks like we've found the place." Tian Uguisu licked the blood off her blade, picked up her spear, and walked toward the stone tablet. Where the mist dissipated, she saw the most Soul Crystal she had ever seen in her life, piled up like a small mountain—but at the foot of the mountain, countless pairs of eyes gleaming with green light were crawling.
The mountain of Soul Crystal glowed with a warm white light after the mist dissipated, as if it contained the moonlight of the entire Shinobi World. But at the foot of the mountain, countless pairs of green eyes blinked, sending chills down one's spine—not just a few scattered mist demons, but a dark, dense mass, from ankle-high imps to shoulder-length ghost soldiers, so crowded that even the wind couldn't pass through, making strange "hoarse" sounds from their throats, drool dripping down their fangs.
Tian Uguisu gripped her spear and took a half-step back. The pale golden flame at the tip of the spear crackled and popped, making the faces of the nearest ghost soldiers pale. She clicked her tongue. "So, it was all a trap set up after all. The Soul Crystal were the bait, and you were the main course?"
As soon as the words were spoken, a section of Soul Crystal Mountain suddenly collapsed with a crash, and two enormous creatures shrouded in gray mist crawled out from beneath. The one on the left was so tall it almost reached the mist layer, its head a skull the size of a millstone, with green flames burning in its eye sockets. Its iron armor was tattered to shreds, and it clutched a rusty, massive axe. The one on the right was shorter but as fat as a ball, its flesh riddled with countless small cracks, each containing an eye that was staring intently at Tian Uguisu, while it swung a chain wrapped in black mist in its hand.
"Is that the Demon King of the Mist Prison?! He's finally appeared." Tian Uguisu's heart skipped a beat—she had heard Tsubasa talk about Hell, and these Oni Clan kings had lived Hell for tens of thousands of years, so ordinary Ninjutsu couldn't hurt them at all.
The Skeleton King slammed its giant axe into the ground, causing the earth to tremble and the mist to shake. "You little outsider, daring to kill my Mist Prison Oni Clan and steal my Soul Crystal..." Its voice was like two stones grinding together, "Today I'll break your bones and boil them into soup, so you too can become nourishment for the Mist Fiends!"
The Fat Ghost King chuckled, the chains whirring in his hands. "Don't scare her! Such a tender body, if I eat her, she might taste delicious, hahaha..."
Tian Uguisu smirked, pointing her spear at the two kings. "Enough talk, let's fight. This old lady is just testing her new weapon." She swiped her spatial ring, and a beam of azure light enveloped the armor, which she then donned— the Earth Spirit Battle Armor was a wedding gift from Tsubasa. This time, she had personally crafted it using materials she had found herself. The armor plates were azure blue, engraved with the same anti-illusion runes as her spear, and a rhombus-shaped emerald was inlaid on the chest, which lit up whenever it touched her Chakra.
At the same time, she thrust the spear forward, and the spear suddenly swelled with a "hum," all the runes that were originally engraved on it lit up, and pale golden flames shot up to half a person's height. A ring of blue light also appeared at the tip of the spear—this was the full form of the Earth Spirit Spear. It had not been fully activated before, but now it resonated with the armor, doubling its power.
"Oh, there's a little treasure here." The Fat Ghost King tilted his head, then suddenly swung the chain, which shot straight at Tian Uguisu's face like a black snake. The chain head even opened a small mouth, revealing sharp teeth.
Tian Uguisu lightly touched the ground with her feet, her body floating back ten feet. At the same time, she twisted her wrist, her spear sweeping horizontally, the flame at the tip brushing against the chains. With a "hiss," the black mist on the chains was burned and smoked, shrinking back half a foot. The Fat Ghost King hissed and gasped, "Breaking Illusion Fire? Just who are you, girl?"
"The one who will kill you!" Tian Uguisu didn't give it a chance to ask further questions, using her Body Flicker Technique to rush forward, her spear aimed straight for the Skeleton King's eye socket. The Skeleton King raised its axe to block, and with a crisp "clang," Mars flew everywhere. It staggered back two steps, a gash cut into the axe handle by the spear tip, a little green flame leaking from the wound, making it howl in pain. "You're asking for death!"
Seeing their king attacked, the surrounding mist demons surged forward like madmen. A short demon soldier swung his bone knife, Tian Uguisu dodged to the side, thrusting her spear backward and striking a demon soldier squarely in the chest. Golden flames exploded with a "boom," and the demon soldier instantly turned into a cloud of black mist, dropping Soul Crystal the size of a fingernail. She casually picked it up with the tip of her spear and tossed it into her spatial ring—she didn't forget to pick up treasures even at a time like this; only she could resist.
But there were simply too many Mist Demons. Killing one only resulted in ten more surging forward. Some of these demons even spewed black mist, which sent chills down your spine and made your Senjutsu Chakra somewhat sluggish. Tian Uguisu gritted her teeth, knowing that her armor and spear alone wouldn't be enough. She took a deep breath and Hand Seals: " Senjutsu: Chakra Burst!"
Chakra surged from her body like a tide, forcing the surrounding Mist Demons back half a step. Just then, her eyes suddenly heated up, the whites of her eyes turned pale purple, Tomoe appeared around her pupils, finally condensing into long straight lines—it was the Rinnegan! She hadn't used it before, but now that she was desperate, she was ready to unleash it and go on a killing spree.
With the Rinnegan, the surrounding mist seemed to slow down, making the movements of the Mist Demons crystal clear. She saw the Fat Ghost King sneak up behind her, his chains wrapped in even thicker black mist, clearly intending to launch a sneak attack. Tian Uguisu sneered, whirled around, Rinnegan at the Fat Ghost King with her Rinnegan: " Shinra Tensei!"
