I'm a demon in Tokyo!

Chapter 317 Three Uesugi Tetsuyas train together... The celestial phenomena are already in the palm of his hand, the white bone wax figure, long time no see.

The power of the Wanling furnace core is exceptionally strong.

It's not just a second heart... it's practically equivalent to twenty hearts combined.

This is a result that Uesugi Tetsuya can experience and perceive without even having to experiment.

So before that, we need to explore the inside and outside of the Wanling furnace core.

After all, everyone else is refining the "Myriad Spirit Cauldron," but he is the only one who is a super-evolved version of the "Myriad Spirit Furnace Core." The inheritance does not clearly mention how to use it or what force to use it.

He had to figure everything out himself.

"Nanjo-nee, you're really amazing..."

Uesugi Tetsuya sighed softly and looked up, only to realize that he was no longer at Nanjo Manami's house.

The walls and furnishings within sight were strangely familiar.

Is this a standard room in the Special Affairs Department?

The two feet that were connected to his heartstrings sensed the hint of his thoughts and replied.
"It was Lady Nanjo who personally brought you here, Lord Tetsu. She even called us over and said that you would need to sleep for quite a while, and then she left."

Uesugi Tetsu nodded, tapped on the hollow iron railing of the bed, and asked, "If Nanjo-nee is gone, who is the current Onmyoji of Arakawa Ward?"

The two-foot-tall man smiled as if he had expected this, and answered with his hands on his hips.
"—Kujou Tsubaki! The one personally appointed by Lord Nanjo... should now be called Kujou-no-kyuu!"

Kujo Tsubaki?
Is it her?

The image of the blind girl with a cane and a black cloth covering her eyes flashed into Uesugi Tetsu's mind.

As far as I can remember, Kujo Tsubaki is very low-key. Ever since she was taken over by the Onmyo-ryo during the first wave, she has never made any noise or achievements, and she has never appeared in any major events.

The last time I saw her was when she came to the Special Affairs Office to choose a shikigami.
My memory is a bit hazy...

It seems that this "Kujou Daiju" does indeed have many outstanding qualities, but he is a low-key person and has not revealed them.

and many more.

Uesugi Tetsu looked at the two-foot-tall man, who was still standing with his hands on his hips but had unknowingly stuck his head under his hand, with a puzzled expression.
"Isn't Kujo Tsubaki an operations specialist for the Bureau of Yin and Yang? How come she's working as a subordinate of the Bureau of Yin and Yang in the Special Affairs Department?"

"po... I don't seem to know much about this."

The two-foot-tall man scratched his cheek, somewhat embarrassed.

That's it.

If Nanjo-nee could get Kujo Tsubaki to be this Yin-Yang Master, then she must have already thought it through.

There's no need to question it further.

Uesugi Tetsu gathered his thoughts and met Nichi's bright eyes. He couldn't help but smile and pat her head gently: "You've worked hard, Nichi."

"It's no trouble at all... Hehe, it's my honor to be able to take care of Lord Che."

The girl, whose height barely exceeded the height of her head peeking out from the edge of the bed, smiled contentedly.

Now she has figured out the height thing—when she is with Lord Che, she uses the height of two, three, or four feet, which makes it easier to move around and also makes it easier for Lord Che to pat her head and encourage her.

As for his eight-foot height, it's basically only usable in combat mode and during combat.

"And Xiao Jia, thank you for protecting him all the time."

Instead of criticizing Kaga Kiyomitsu for running away, Uesugi Tetsu chose to encourage him.

"As long as my master is safe, I'm happy..."

Kaga Kiyomitsu's voice was still soft and sweet, but it caused a slight glint in the eyes of the two-foot-tall man.

"By the way, how much time has passed since Nanjo-nee brought me here?"

Erchi, who had been scrolling through his phone just ten minutes ago, immediately replied, "About sixteen hours."

That hasn't been long.

Uesugi Tetsu stretched his body, quickly changed out of his cheap clothes into casual wear, picked up Xiao Jia, and asked the Second Master,

Did Manatsu and Akatsuki Ran go to Hokkaido with Nanjo-nee?

“Manatsu-chan said they have to wait until the area is cleared up before going over, because Hokkaido isn’t very safe right now.”

"I've already gotten to know Shizuma Manatsu quite well," replied the man from the two-foot-tall family.

Even the Special Affairs Bureau's base cannot guarantee absolute security, so it seems that the environment in Hokkaido is indeed not very good.

Sensing the familiar fluctuations of the sword domain, Uesugi Tetsu asked, "Then Ririko must be with Manatsu and Kitano-san, right?"

"Mmm." Erchi nodded. "The three of them are probably playing games together."

Ririko playing games?

That's rather unusual...

Just as Uesugi Tetsu was about to open the door and go out for a quick look around, he saw the progress notification that most likely appeared after he fell into a deep sleep.

[Current Trial Progress: 0.13%]

The price suddenly rose by 0.13%, which is definitely related to Nanjo-san.

Behind him, the two-foot-tall lady took out a crumpled piece of paper from the hem of her skirt, which had pockets, and spoke.

"And Lord Che, Lord Nanjo said that we need to go to the Minamoto family to get the Spider Cutter in the next couple of days. This matter can't be delayed for too long."

Secondly, I must go to Kyoto in five days to meet the Sword Saint.

Upon hearing this, Uesugi Tetsuya withdrew his hand from the doorknob.

"I see."

He sat back on the bed and pressed down on the restless little Jia.

The former is an approximate time and not very important; but the latter absolutely requires you to be there on time.

If we miss this opportunity, we'll likely never have another chance to see that legendary swordsman in the near future.

These past two days have also been around the time when the four-tailed fox transforms into a three-star fox.

Upgrading it to three and a half stars also requires spending a small amount of Soul Ash.

That's easy. I'll just go to Edo-jo Bank and withdraw some cash later.

As for the new demon incarnation card pool, it will most likely only be available after he ascends to the level of a demon god.

With this in mind, Uesugi Tetsuya put aside his idea of ​​taking a walk and calmed down to feel the presence of the All-Spirit Furnace Core.

It's not in the body... of course.

Uesugi Tetsu skillfully looked inside his right chest and, through a blur of vision, saw the priceless All-Spirit Furnace Core.

The furnace core and the Qi Sea are not in the same space, but it is still closely connected with Uesugi Tetsu's body and even his Qi Sea.

In the colorless darkness, a delicate sphere emitting a dim purplish-red light was slowly rotating and pulsating, making it impossible to tell how much energy it could unleash.

The surface of the Wanling furnace core is also covered with a thin, undulating, blackish-red film that looks like a living thing.

Uesugi Tetsu recognized it; it was Zhou Tianyan Armor.

At the same time, one can clearly feel the progress that Zhou Tianyan Armor has made as a result.

—The transition from Flame Armor to Zhou Tian Flame Armor is now complete, and the ninth Zhou Tian Flame Seed has been fully condensed.

This efficiency is undeniably high.

Even if Uesugi Tetsuya did all of this himself, it would take him about the same amount of time, and he would also need to use the aid of soothing incense ash.

Otherwise, it might be slower than the idle income of the Wanling Furnace Core.

"Tsk tsk tsk, the super-evolved version of the Myriad Spirit Cauldron is indeed incredibly effective."

Uesugi Che couldn't help but marvel, because there was still an empty slot in the Wanling Furnace Core waiting for the Yin-Yang Technique to be placed inside.

In this way, even if the Wanling Furnace Core has no other functions, it is equivalent to having two single-minded and tireless selves constantly practicing Yin-Yang techniques in the dark room day and night.

As long as no spiritual power is injected into the furnace core, the automatic operation will not stop no matter what happens in the outside world.

This single action was almost equivalent to tripling Uesugi Tetsuya's training progress.

The next step is to consider which Yin-Yang technique to include.

Uesugi Tetsu glanced at the Onmyojutsu section of his skill list—

Basic Five Elements Yin-Yang Techniques, Spirit Control Techniques, and Five Thunder Techniques.

Okay, that's all.

It was pitifully little. The Five Elements Yin-Yang Technique was the first to be ruled out; Uesugi Tetsu hadn't expected these little tricks, mostly used in everyday life, to bring him much help in the first place.

After his gaze lingered between the Spirit Control Technique and the Five Thunder Technique for a moment, Uesugi Tetsuya made his decision.

Let's put the Five Thunder Technique in there.

Since the art of spirit control is something that needs to be practiced at all times, let him bear this heavy responsibility.

But just as Uesugi Tetsu was about to put the Five Thunder Technique into this "empty space," a layer of goosebumps rose on his back.

—If I were to throw the Five Thunder Technique in now, not only would I explode on the spot, but the entire Arakawa Ward, and even the surrounding wards, might not even exist anymore.

Danger, danger.

It wasn't until Uesugi Tetsu removed this thought that the premonition of death, like a thorn in his side, gradually disappeared.

Another point is the [Fusion] effect of the furnace core, which is extremely simple to explain – you only need to inject spiritual power.

As soon as this thought crossed his mind, Uesugi Tetsu felt a chilling premonition of death creeping into his bones once again.

Forget it, let's not blow up the Arakawa Ward headquarters...

It seems I'll have to go to the mortal realm later to learn more about the Myriad Spirit Furnace Core.

If it weren't for the stability provided by the Zhou Tian Yan Armor, this thing might have set off a spectacular fireworks display for itself at any time.

No wonder this thing, despite being a powerful Yin-Yang technique, has been relegated to the "cold palace" of exchangeable items.

At last.

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

Uesugi Tetsu's gaze fell upon this line of description.

The "walking" mentioned in the words undoubtedly refers to oneself.

But who is the "Demon King"?
He thought of the Demon King gacha pool, the Demon King bento box, and the Demon King's conscience contract—was that "Demon King" related to this "Demon King"?
The information was so scarce that even Uesugi Tetsu had no clue where to begin.

Let's go to the Tokoyomi district and set off some firecrackers instead...

"Erchi, let's go."

"Great!"

After crossing the Deep Sea with increasing ease, Uesugi Tetsu opened his eyes on the wasteland above Kisaragi Station.

This place has no monsters or demons; it's all wasteland and bare hills, making it perfect for an experimental site.

After instructing Erchi and Xiaojia to play by themselves, Uesugi Tetsu sat cross-legged next to the shrine and began to explore the Wanling Furnace Core, matching every detail of the now-finished product with all the parts in his memory.

Hours later, Uesugi Tetsuya's gaze swept over every minute detail of the Wanling Furnace Core hundreds of times.

The experience gained in the furnace core casting process has been transformed into practical experience.

At this moment, Uesugi Tetsuya had the idea of ​​injecting spiritual power into it again, and the premonition of death disappeared, leaving only a subtle sense of danger.

"Give it a try."

Uesugi Tetsu transformed into a four-tailed fox, wearing a red Hannya mask at his waist, and then added the Hundred-Eyed Demon incarnation, directly increasing the number of Hundred-Eyed Demon's eyes to 90, activating all of them with the All-Seeing Eye.

Looking forward to it.

Uesugi Tetsuya showed full respect for the first time he infused spiritual power into the core of the Myriad Spirits Furnace.

"Little Jia, come back." Uesugi Tetsu glanced at the two who were digging in the ground a hundred meters away. "It's not safe around here."

In just a few seconds, the two of them scurried back to safety, relying solely on their inner feelings to sense what Uesugi Tetsuya was about to do.

Uesugi Tetsuya didn't hold back, connecting all his senses to the heartstrings.

Then, a drop of pure liquid spiritual energy passed through the membrane of the Zhou Tian Flame Armor and fell into the core of the Myriad Spirits Furnace.

pat.

A voice that doesn't exist was heard.

Thus, fusion was born.

A silent roar, comparable to the detonation of a nuclear bomb, exploded inside Uesugi Tetsuya's skull, filling all his senses.

Having lost all five senses, only the eyes of the Hundred-Eyed Demon continue to watch dutifully.

Rumble!
The ground trembled, and the spiritual energy between heaven and earth was directly stirred into a chaotic mess, so disordered that ordinary Yin-Yang Masters and demons could not absorb it at all.

A bright blue light shone from the fingertip of Uesugi Tetsuya's right hand, and then expanded, expanded, and expanded again in the time it took him to control it.

Before the cracked fingertips, a deep blue glow surged toward the continuous mountain range directly in front.

Vanished in an instant.

In the vision of the Hundred-Eyed Demon's Eye, a huge, empty hole with perfectly smooth edges had appeared in the center of the mountain, which was tens of meters high!

With a splitting headache and blood gushing from his body, Uesugi Tetsuya looked up and saw the moon rising on the horizon through the hole.

With the force of a single finger, it pierced through the entire mountain, which was hundreds of meters high!
In my heartstrings, the screams and exclamations of the two little ones rose and fell.

In an instant, Uesugi Tetsuya felt his headache and body pain disappear. He felt clear-headed and extremely relaxed!
Just injecting such a small amount of spiritual energy into it can achieve this effect...

Uesugi Tetsu examined the core of the Myriad Spirits Furnace again and found that it had not changed at all. Even if the same amount of spiritual power was put in, it would still give the same answer.

The key is whether you can stabilize the furnace core every time it's firing, and whether your body can withstand the transmission of terrifying power.

"good very good."

Uesugi Tetsu didn't say much, but continued to inject different doses of spiritual power into the core of the Myriad Spirits Furnace again and again.

Bold and unrestrained.

As I said before—in this world, Uesugi is fearless of death!
Several hours later.

Having been transformed into coke once, Uesugi Tetsu stared at the tiny arcs of electricity flickering in the center of the furnace core and let out a heavy sigh.

[You have implanted the Yin-Yang Technique - Five Thunder Method into the core of the Myriad Spirits Furnace!]

[Currently available engraving slots: 0/2 (Zhou Tian Yan Jia - Beginner, Five Thunder Technique - Expert)]

It took a full ten hours and a life to finally throw the Five Thunder Technique into it.

Even though Uesugi Tetsu had already figured out the daily operation of the Myriad Spirits Furnace Core at the cost of the disappearance of the surrounding mountains, the process of imprinting the Five Thunder Technique was still dangerous.

If it weren't for the furnace core being encased in the Zhou Tian Flame Armor to increase stability, and the double assistance of the Hundred-Eyed Demon Eye and the Spirit Control Technique, this life would probably still be electrocuted into charcoal.

"But now..."

In the darkness of the inner vision, the purplish-black furnace core whirred silently.

Satisfied, Uesugi Tetsu left Kisaragi Station and opened his eyes again in the damp thatched hut of Edo Castle.

"Mmm, this familiar smell, I haven't smelled it in so long..."

Uesugi Tetsu took a deep breath and listened to the continuous sound of rain between heaven and earth.

Laughed.

With his hands in his pockets, he kicked the creaking old wooden door, which had apparently been reinstalled by someone, into splinters and walked into the rain.

Uesugi Tetsu looked up, and the thick, dark clouds, as heavy as a city, were reflected in the flames.

"This rain just won't stop."

As the unpleasant words fell, a crimson pillar of spiritual energy, imbued with a hint of the power of the Flame Armor, shot straight into the sky.

Then, it exploded with a deafening roar.

In an instant, the dark clouds over Edo Castle, along with the raindrops still floating in the air, were swept away and vanished into nothingness.

A wisp of light appeared, landing on the muddy roads of Edo Castle after a long absence.

"That's not bad."

Uesugi Tetsu nodded in satisfaction, enduring the excruciating pain tearing through his body, and looked toward the two fierce-looking men at the end of the road, their arms around each other, staring blankly upwards.

Two acquaintances whom he had already sensed but was unaware of.

Skeletons and wax figures.

"Long time no see, you two."

Two pairs of surprised and uncertain gazes shot over, and Uesugi Tetsuya revealed a kind smile.

"Have you forgotten me?"
