I'm a demon in Tokyo!

Chapter 316 Perfect Forging—Legendary Quality All-Spirit Furnace Core! My darlings of Edo Castle, here I come…

"Wait a minute? Wait a minute for what?"

Nanjo Manami chuckled, then her smile grew increasingly strange: "Uesugi-kun, you're not scared, are you...?"

Because there are very clear records in the lineage of the Wanling Cauldron.

The forging of the Myriad Spirit Cauldron must be carried out from the very beginning by being implanted into the flesh and blood of the future owner.

As something that was initially envisioned to be as important as the "heart" for Onmyoji, the Wanling Cauldron must first be connected to the "perception" of the whole body.

Then start casting from scratch again.

For this reason, the entire process is extremely painful, a kind of suffering that ordinary people cannot endure.

That's why Nanjo Manami asked a curious and odd question, thinking she was finally going to see some of the plot she wanted to see.

"It's not such a small matter..."

After repeatedly cleansing his body with Qi and spiritual power, Uesugi Tetsuya's thoughts gradually returned to normal.

He waved the Hungry Ghost Pot in his hand at Nanjo Manami with a rather helpless expression: "Here, it is."

At this moment, Nanjo Manami's gaze shifted from Uesugi Tetsu, who had just shown an unusually weak demeanor.

Then he paused, stunned.

Because she had seen similar utensils before.

The Nanjo family once had such an existence.

They usually contain very rare materials, or rare but even more dangerous ones.

Uesugi Tetsuya is giving this to me now because he wants to...

Nanjo Manami's doubts were cut short by her quick response before they could even arise.

After a moment of silent eye contact, Nanjo Manami asked,
"Is it filled with the blood of Huojin?"

She didn't beat around the bush by saying "that person," partly because as long as there were no complicated rituals or spells, and she didn't call him by his full name, it was almost impossible to summon misfortune.

Secondly, it's because of Uesugi Tetsu.

From the moment he took the initiative to ask me if the blood of the calamity could be used as material, to now, just a few hours later, he has filled the calamity's blood into a pot and placed it in front of me to look at.

To say that Uesugi Tetsuya and Mokuzu didn't have some kind of ambiguous, mysterious relationship...

Nanjo Manami definitely didn't believe it.

Therefore, it's impossible for Uesugi Tetsu to be noticed or disliked for such a trivial matter.

—That's to be expected, because right now, Mojin is walking in the assembly, focusing all his attention on manipulating a giant slithering snake that is thousands of blocks long.

boom.

Just then, Uesugi Tetsu slapped himself on the forehead, dispelling the last vestiges of his drunkenness: "Finally sober... So this is what it feels like to be drunk."

"It's so uncomfortable."

He stared at the materials scattered on the ground behind Nanjo Manami for a long time, remembering that she had said they wouldn't arrive for several days.

Uesugi Tetsuya is certainly not stupid.
"Did you bring all of these yourself, Nanjo-nee?"

The woman nodded naturally: "I've made so many trips, so I have to pay extra."

Uesugi Tetsu naturally changed the subject.

"Oh right, what did you just say, Nanjo-nee?"

Nanjo Manami: ...

She sighed and repeated what she had said before.

Uesugi Tetsu nodded and handed over the Hungry Ghost Pot: "It's His blood, is one drop enough?"

a drop.

Even Nanjo Manami couldn't help but lean back slightly upon hearing this quantifier.

How can blood of this level be measured in "drops"?
Uesugi Tetsu clearly doesn't know anything about Onmyodo or unorthodox practices, so how did he get involved with the Calamity, which is located in an unknown place in the world of the living?
Could it be that Masatsu is Uesugi Tetsu's long-lost mother...?
Always ready to grant requests?

That explains the famous scene in the seeding battle where Tsuchimikado Arashi was attacked backfired.

He really is a man full of mysteries.

Just like myself.

Nanjo Manami took the Hungry Ghost Pot: "It's definitely enough as material."

She stared at the copper stopper for a while, and then, driven by a combination of need for confirmation and curiosity, she unscrewed it, revealing a small gap.

In an instant, the drop of blood, suspended in the pot, was reflected in her eyes.

A sharp, stabbing pain shot through my eyes.

Nanjo Ai closed the stopper casually, clicking her tongue in amazement: "It's actually the real thing..."

"All right."

Nanjo Manami got up, stretched her legs which were wrapped in slightly taut black stockings, and then changed her posture to kneel properly on the open ground covered with tatami mats.

She became serious, patted her thigh, making a deep sound that was somewhere between crisp and dull: "Wash up first or just lie down?"

Uesugi Tetsu:?

"Nanjo-nee, what are you doing?"

Nanjo Manami replied, "You want me to start creating the Pangu Cauldron inside your body from a distance, artificially increasing the difficulty of forging and the probability of death, right?"

That makes a lot of sense.

When forging the All-Purpose Cauldron, it is best if the body of the person being forged is in contact with the forger, as this helps to improve the accuracy of perception.

Uesugi Tetsu nodded, and was about to lie down when his gaze swept over the eye-catching sheer stockings: "Nanjo-nee, what are you doing wearing these?"

Nanjo Manami replied: "I don't understand how clothing with slight tension can relieve muscle tension that has been present for a long time?"

The casting of the Wanling Cauldron should minimize external interference and influence.

That makes a lot of sense.

Uesugi Tetsuya, who had previously studied marathon races, knew that the "ice sleeves" worn by athletes worked on the same principle.

However, although these words made a lot of sense, Uesugi Tetsu felt that something was not quite right.

So he opened his mouth again: "Then what position should we use..."

The next instant, Nanjo Manami interrupted the spellcasting.
"Just don't say anything! Get over here!"

An invisible spiritual force lifted Uesugi Tetsuya up like a chick, and landed his head precisely on Nanjo Aimi's legs.

A soft yet elastic warm touch came over me.

Uesugi Tetsu blinked, deeply appreciating the immense waves and the abundance.

"Alright, just stay put from now on."

Nanjo Manami's calm voice came through, and Uesugi Tetsu could tell that she had completely entered her daily work mode.

"—How long can you not move? The forging of the Myriad Spirit Cauldron must take quite a long time."

"A day or two?"

As Nanjo Manami finished speaking, a small wave swirled around: "That's about the time, at the shortest it should be ten hours or so."

Uesugi Tetsuya's pupils contracted slightly, and he didn't even have time to appreciate the magnificent natural scenery.

In my memory, the tradition of the Myriad Spirit Cauldron states that the minimum forging time is over a week, and if many rare materials are used, the time will double...

Not only does it take more than a month, but it also requires several master-level experts to personally handle the task and support each other.

In case the All-Powerful Cauldron explodes halfway through its casting due to a slip of the hand.

While Uesugi Tetsu was lost in thought, out of the corner of his eye, bottles and jars flew out of the wooden box and were arranged in a circle around Nanjo Aimi, some near and some far.

Although the operation was simple, the strength of each spiritual energy thread was far beyond what Uesugi Tetsuya could achieve.

As expected of Nanjo-nee, who comes from the Nanjo family, her mastery of spirit control techniques has probably reached an absurd level.

Forget it, I'll just lie here and relax from now on.

Doing nothing is the best help.

—Since Nanjo-nee helped him open his heart, he might as well take the opportunity to experience the magnificent natural phenomena of the Southern Hemisphere.

Weird.

Uesugi Tetsu used a large amount of prepared calming incense ash from his storage backpack to gather his scattered thoughts into a single bundle.

During the forging of the Wanling Cauldron, he not only had to remain still and persevere, but he also had to be able to perceive and remember everything that Nanjo Ai was doing in his body with the clearest understanding.

From beginning to end, we must pay close attention to every detail, follow up on every step, and implement every key point!
Only in this way can one gain the deepest understanding of the Myriad Spirit Cauldron and master it at the fastest speed.

Silently, Uesugi Tetsu opened thirty Hundred-Eyed Demon Eyes within his body, observing everything that was happening inside without putting any strain on his body.

Nanjo Aimi paused slightly, but quickly returned to normal.

Where is the heart located?

"Left side... Nanjo-nee, you even have to ask about this?"

"Who knows if you've been lying all along? What if you accidentally cut the wrong thing and I have to sew it back up? That would be such a hassle."

Just as Uesugi Tetsu was about to sigh in exasperation, he felt his upper body clothing automatically undone and fall off.

Then, the cold scalpel plunged into the flesh without resistance, abruptly slicing open his entire right chest, revealing the vibrant flesh and shimmering thunder bones.

The tiny amount of complex spiritual energy released just happened to suppress the automatic healing of Uesugi Tetsuya's body.

"Hiss..." "Don't move, and it's best not to make a sound."

Uesugi Tetsu immediately froze, like a stone statue, focusing all his attention on the area around the wound.

Next, Uesugi Tetsu began to "watch" Nanjo Manami cut open her own flesh bit by bit at close range, and then opened the small bottle labeled "Ama-Iwato Ashes".

The dust, a hundred times colder than a scalpel blade, rustled down, bringing a new clue.

【Please note! 】

[“Nanjo Manami” is helping you forge the extremely dangerous Great Yin-Yang Technique, the All-Spirit Cauldron…]

[Your Spirit Control skill proficiency is increasing...]

Uesugi Tetsu, who was focused on everything, did not notice the prompt in time, nor did he see the different color of the four characters "Nanjo Aimi".

It showed a faint black color.

He could only sense Nanjo Manami's incredibly precise and superhumanly agile manipulation of the spiritual scalpel and countless spiritual threads as she dissected his body.

He is a thousand times more skilled than the most skilled surgeon.

Then, feeling one rare and precious material after another come into contact with his flesh, nerves, bones... and then caressing his spirituality and soul, which brings torment to his fickle will.

Or, to put it another way, refined tempering.

A thorough inspection of every part, inside and out.

If there is even the slightest flaw in Uesugi Tetsu's heart, it will be magnified infinitely, causing the forging of the Myriad Spirit Cauldron to fail.

Although she survived thanks to Nanjo Manami's protection, she was no longer destined to learn this great Yin-Yang technique.

Unfortunately not.

Uesugi Tetsu's mind became increasingly refined and powerful through the tempering he received from observation.

In Nanjo Manami's hands, the Spirit Control Technique operated as naturally as the rules of heaven and earth, linking to the materials that had been initially processed.

After establishing a solid foundation, the material undergoes repeated refinement to form a perfect "embryo," which is then shaped into the desired form and further purified...

The exquisitely beautiful trajectory of spiritual energy flow was displayed before Uesugi Tetsu's eyes without reservation, leaving him mesmerized.

From the outside, one would see a stunningly beautiful woman in an office lady uniform lying on the lap of a young man whose right chest has been completely ripped open, yet whose eyes remain fixed on something else.

In mid-air, pieces of faintly glowing materials flew continuously into the blood cave.

The woman's expression was focused and serious, as if she were creating some rare treasure.

It was like some kind of bloody and terrifying cult sacrifice ritual was underway.

—Based on the ash of the Heavenly Rock Cave, with the reverse scale of the Yamata no Orochi as the shell, the hair of the Underworld as the passage connecting the inside and outside, the fragments of the medicine pot harmonize everything, and the tears of the Mermaid King become the starting power…

There was only a pitiful amount of each material.

But even this "little bit" was enough to make Onmyoji who learned of this place rush to grab it.

Let alone ordinary Onmyoji, even demons and gods would normally find it difficult to find one of these items.

In order to catch the last train to invest in Uesugi Tetsu, a rising star with unlimited potential, the powerful figures in the industry willingly bleed money.

The sun sets, the moon rises.

Unbeknownst to either of them, the Myriad Spirit Cauldron had already taken shape as time passed.

Just one step left.

boo.

The copper stopper of the Hungry Ghost Pot was opened again.

The beautiful blood droplets inside floated up and, guided by Nanjo Manami, hovered above Uesugi Tetsuya's chest.

Chi chi chi——

A dim yet pure purple light shone within this sphere, the size of a heart, and roared under the gaze of every hundred-eyed demon eye.

pat.

Drawn by gravity, the blood droplet fell into the roaring engine of the Myriad Spirit Cauldron.

Boom boom boom! ! !
An indescribable tremor resounded in Uesugi Tetsuya's "eyes," and the originally dim purple light soared into the sky, becoming no different from the rising sun.

But then, the entire Wanling Cauldron emitted a mournful wail.

It seemed about to collapse, unable to hold on any longer.

Nanjo Aimi remained unfazed and implanted the pre-prepared prototype of the Zhou Tian Yan Armor into it.

A dark red light shone.

Although insignificant, it perfectly suppressed and healed the impulse of the newly formed Myriad Spirit Cauldron, reducing a massive collapse from the inside out to nothing.

"finished."

Under Nanjo Aimi's gaze, the purplish-black Wanling Cauldron slowly dimmed its light, truly connecting with Uesugi Tetsu's body, and then fell silent and invisible.

It truly transformed into Uesugi Tetsuya's spiritual energy structure and entered a space different from the one where his physical body was located.

Just like the Qi Hai point.

In that instant, feeling the threat of death leave every pore of his body, Uesugi Tetsu immediately opened the number of Hundred Eyes of the Demon to 50.

With the last of his spirits and all his might, he observed the moment when the Myriad Spirit Cauldron merged into himself.

Unbeknownst to Uesugi Tetsuya, a tremendous force amplified the previously blurry scene, making it incredibly detailed.

After that moment ended, Uesugi Tetsu's consciousness automatically plunged into darkness due to the excessive pressure.

Fell asleep.

……

It was the two-foot-tall man who woke up Uesugi Tetsuya.

"Lord Che? Lord Che?"

Another giant wave surged and rolled before our eyes.

But for some reason, Uesugi Tetsuya had absolutely no interest in observing in detail.

After all, whose child is this...?

My child.

He sat up, took a deep breath, and felt an immense, rhythmic surge of power erupting from deep within his right chest.

Like a heartbeat.

With his mind clear, Uesugi Tetsuya was able to begin clearing away the prompts in front of him.

[Having observed Nanjo Manami's practice and application of spirit summoning techniques at close range for an extended period, your understanding of spirit summoning techniques has deepened, and your proficiency has greatly increased!]

[Your skill, Spirit Controlling Skill proficiency +1944! ]

【Spirit Control Technique - Qi (Master 5121/8000)】

An unexpected look of astonishment flashed across Uesugi Tetsuya's eyes.

But it's a pity.

Today's main focus is not on spirit control techniques.

[You have completed the forging of the Great Yin-Yang Technique - Myriad Spirit Cauldron!]

[Due to the high quality of the materials used to forge the All-Spirit Cauldron, its completion rate exceeds 100%! Your Great Yin-Yang Art vessel, the "All-Spirit Cauldron," has been upgraded to the "All-Spirit Furnace Core"!]

The golden "All-Spirit Furnace Core" bursts with brilliance!
[You have obtained the All-Spirit Furnace Core!!!]

[Because of your meticulous observation and experience during the forging process of the All-Spirit Furnace Core, your control over the All-Spirit Furnace Core has greatly improved!]

dong... dong... dong...

In the void, an extremely slow and heavy pulsation echoed continuously through Uesugi Tetsuya's five senses.

"Two feet, have you seen Nanjo-nee?"

"Nanjo left a while ago, saying she went to Hokkaido for a work report? Speaking of which, what does 'work report' mean, Lord Che?"

Uesugi Tetsu hummed in agreement, gazing at the gleaming gold panel amidst the two synchronized, silent pulses.

He gazed at his first [Legendary] item.

【All-in-One Furnace Core】

[Quality: Legend]

Effect 1: Imprint Rotation. The Myriad Spirits Furnace Core can automatically operate all the Yin-Yang techniques placed within it, gradually perfecting them.

The deeper your understanding of the Yin-Yang arts imprinted in the core of the Myriad Spirits Furnace, the faster the core of the Myriad Spirits Furnace will operate.

[Effect Two: Fusion. Input spiritual energy, output physical power.]

[Effect Three: Ascension. Through repeated forging, the quality of the All-Powerful Furnace Core can be further improved.]

[—Walk, and the Demon King will be with you.]

Uesugi Tetsu listened silently to the deep, earth-shaking throbbing sound, and thought to himself...
"It seems it's time to bring back those talking creatures that roam freely throughout Edo Castle..."

"My soul has turned to ashes."

　Uh... it was originally 5k words, but I had to cut 300 words.

　　Actually, this chapter doesn't contain much; it's just a little bit of praise for the giant waves.
