I'm a demon in Tokyo!

Chapter 206 A dramatic change with a 3% historical impact, the death of Imagawa Yoshimoto from illness! The Totsuka Sword, defining the sea of ​​qi!

Only a few seconds have passed?

Uesugi Tetsuya, who was prepared to wait all day and temper his bones along the way, stared with his mouth agape, taking several seconds to recover his surprise.

He removed the mask from his face and, upon discovering it was indeed a white woman's mask, murmured with slight confusion.
"I didn't wear it wrong..."

"It's not an adult's problem, of course."

The small openings and closings on the straw face produce a unique rustling sound as the straw rubs against each other.

Katsumi snapped his miniature folding fan shut, hopped onto a branch in front of Uesugi Tetsuya in a few swift movements, and looked him straight in the eye as he spoke.
"Recently, the gentle aftershocks of the wave have arrived... I have also taken this opportunity to spread out many clones and reconnect with many clients who had lost contact before."

One of his clones happened to land nearby and rode the waves into the mortal world.

I see……

Uesugi Tetsu recalled the towering waves he had just seen sweeping overhead.

mild?

real or fake?

What does it mean to be anything but gentle?
He tentatively asked, "Are you referring to the aftershocks of the current world that will fall in two days?"

"Your Majesty, it's clear."

Sheng Hai nodded vigorously immediately—because his clone was only the size of a palm, and if his movements were slightly smaller, it would be difficult for people to see him clearly.

This is not good.

It could lead customers to misunderstand his intentions.

“Speaking of which,” the straw man looked Uesugi Tetsuya up and down for a moment, and couldn’t help but exclaim in amazement, “My lord, in just a few days, your strength has already far surpassed what it used to be.”

Sheng Hai couldn't help but laugh out loud: "It seems my judgment is indeed sharp!"

"It was just good luck that I stumbled upon a mysterious ghost realm; it's nothing to brag about."

Uesugi Tetsu shook his head—he wouldn't tell much truth to Katsumi, this businessman.

Who knows if this information will be given to other demons and monsters in the mortal world as "bonus information" in the future?

Sheng Hai gave a noncommittal "hmm," clearly indicating his disbelief.

But he didn't ask any more questions; it's not a good practice to pry into customers' private information.

Merchants, of course, come here to do business.

"So, an adult."

Sheng Hai interrupted the previous topic and bowed slightly: "What is the purpose of summoning me here today?"

"Selling and buying".

Uesugi Tetsu answered succinctly, waving his hand to take out several large items he wanted to sell from his storage backpack: "Lord Katsumi, please take a look."

The Plague Bell, the Iron Pestle, the Bloodstained Broken Hat, and the Foot Guard Armor...

As for the other miscellaneous props and materials, he did not take them out for the time being.

—The effect of the Plague Bell is eight times stronger than that of Kaga Kiyomitsu, and is even weaker; Hinaka can only summon one and a half stars at most, and two stars at most, which is no longer enough to keep up with his pace.

Needless to say, Uesugi Tetsu never intended to use the armor from the very beginning.

As for the refined steel pestle, it's not too late to decide after we see what price Sheng Hai will offer.

The eyes of the straw figure resembling Sheng Hai immediately lit up.

He marveled at the items, finally fixing his gaze on the matte iron pestle that gleamed in the sunlight.

"Not bad!"

Sheng Hai cheerfully opened his folding fan: "The items that you wish to sell, sir, are all of very good quality!"

"However, it is really not easy for my clone to cross the waves and reap the rewards."

The straw man pondered for a moment: "My lord, why don't you set a time, and then put on the mask in the mortal world? I will definitely arrive in a short time."

He pointed to the fine iron pestle and said, "Especially this iron pestle, I have a demon-level customer who is in need of it, and I can definitely offer a price that satisfies you."

Sheng Hai cupped his hands in greeting: "Therefore, I humbly request that you leave it here for the time being."

Even a god-level being wants to use a rare-level weapon?
No... it's probably the effectiveness of this iron pestle that made it so durable and that's why it was chosen.

Uesugi Tetsu smiled and nodded.

"As it should be."

After reaching a consensus, Sheng Hai continued to ask, "What else does the master want?"

"Business has been booming lately, so even in my physical body in the mortal world, it's difficult to move around. Therefore, please tell me what kind of items you would like to buy, and I will have my clone bring them when I come down."

"All five elements materials, regardless of quality, are required."

Let's set the time for one day from now.

Uesugi Tetsu flicked the Kaga Kiyomitsu at his waist and continued his nonsense: "I recently found a craftsman who wants to reforge the weapon."

"I understand..."

Just as Katsumi was about to leave, bowing and holding his folding fan, his gaze was immediately drawn to Kaga Kiyomitsu, whose sword blade was protruding from Uesugi Tetsu's waist.

Don't move.

Buzz?
Kaga Kiyomitsu felt the gaze and flinched slightly in confusion.

Sheng Hai's eyes widened, and he immediately raised his voice: "My lord—!"

"This is not for sale."

Uesugi Tetsuya rarely interrupted the other person.

He replied calmly, and slapped the curious Xiao Jia back down.

This brat always has to cause some trouble before he'll settle down.

Uesugi Tetsu sighed inwardly—it seemed that Kakashi was unaware of how attractive he was to others.

Katsumi only realized his lapse in composure after Kaga Kiyomitsu's entire body was back in its sheath.

"Feel sorry."

He composed himself and jumped down from the tree branch apologetically: "If there is nothing else, sir, I will take my leave to prepare the goods."

Uesugi Tetsu nodded: "Mr. Katsumi, have a safe trip."

The straw figure bowed again.

He turned and leaped away, disappearing from Uesugi Tetsu's sight in an instant.

After the strangely dressed scarecrow left, Kaga Kiyomitsu, who had just been pushed back down, secretly extended a small section of his sword blade again and asked curiously,
"Little Jia... Little Jia can't understand what the master and the scarecrow are saying..."

Uesugi Tetsuya remained silent and pursed his lips upon hearing this.

Judging from the honorifics and roundabout ways he and Shenghai used in their conversation...

If Kaga Kiyomitsu could understand it, he would definitely make him a little certificate the next day to be awarded as the "Most Intelligent Genius Katana in the World".

Recalling what had just happened, Uesugi Tetsuya angrily tapped Kaga Kiyomitsu's sword drum with his fingers.

I gave Xiao Jia a sharp rap on the head.

"Well."

Kaga Kiyomitsu shuddered, uttering a look of frustration and confusion.

After feeling this, Uesugi Tetsu touched the spot he had just knocked, somewhat reluctantly, and sighed.
"Little Jia, remember not to draw your sword from its sheath when you see strangers in the future."

Kaga Kiyomitsu was puzzled by the earthquake.

Uesugi Tetsuya then threatened, "Because it might be a bad guy! A bad guy might kidnap you! Then you'll never see me again!"

Kaga Kiyomitsu seemed to be quite taken to this scare tactic, remaining completely still without even responding.

Uesugi Tetsu nodded in satisfaction.

That's better.

Otherwise, if Kaga Kiyomitsu were to immediately start peeking around and observing every place he visited, it would definitely attract a lot of unnecessary trouble.

Uesugi Tetsu smiled as he transformed into a four-tailed fox, opening LINE on his phone while simultaneously using his spirit control technique to perceive the changes in the world.

While the LINE interface was still loading in a loop due to the poor internet connection in the mountains, the spirit summoning technique provided Uesugi Tetsuya with the answer from countless clues.

"The aftershocks of the wave won't arrive so quickly, will they?"

Although it's not too far, it means I can at least take a proper vacation and relax.

Uesugi Tetsu grinned and clicked on Nanjo Aimi's grayed-out profile picture after LINE finally finished loading.

With a snap, her latest signature popped up.

[—I'm on vacation, please do not disturb.]

have to.

I reckon that Nanjo-nee had just finished drinking and was still fast asleep.

Uesugi Tetsuya logged out and then clicked on the profile picture of Huijue, who was also offline, and sent him two messages.

[Moon Sand: Master, my shikigami, Two-Foot Master, has had its perception corrupted by absorbing too much willpower, and has therefore sealed itself within its vessel.]

[Moon Sand Sauce: If you have any good solutions or ideas, please contact me as soon as possible.]

After thinking for a moment, Uesugi Tetsuya added a thank you emoji.

Well, now we just have to wait for the answers from professionals.

Uesugi Tetsuya, who was about to click off all the red dots as usual, paused for a moment and realized that there didn't seem to be many red dots in the last two days.

Everyone seemed to have their own things to do... except for Kitano Runa, who was like an otaku dumping garbage into a tree hole, sending him a whole bunch of Kuku messages.

Even if he doesn't reply, I'll still send it.

When Uesugi Tetsu clicked in, he found that she was actually asking him which anime series he had watched in April, and then recommending a bunch of "masterpieces" and "excellent works".

Not only that, but they also released a preview PV link for the new anime series starting in July, and then talked at length about it.

There were also a lot of emojis mixed in, otherwise the red dot wouldn't have turned into "99+".

If he were living in a world without magic, he might get along very well with Runa Kitano.

but now……

Uesugi Tetsu sighed and replied, typing on the keyboard.

[Tsukisuna-chan: Sis, I don't have time to watch anime!]

After that, I joined the Arakawa District seed tournament group that I had been pulled into before.

In just a few days, the number of people in this group has increased significantly, almost doubling.

Uesugi Tetsu nodded in satisfaction: "It seems there are quite a few promising newcomers."

After browsing the group chat again, Uesugi Tetsuya found that everyone was discussing some very simple questions. Suddenly, a wave of drowsiness washed over him, and his eyelids began to droop.
"Why does it feel like the spiritual energy in the world is so abundant?"

Uesugi Tetsu yawned: "It's making me dizzy..."

Putting his phone back in his pocket, Uesugi Tetsuya decided to take the train home and get a good night's sleep, letting his sleepiness carry him away.

Before long, he arrived at the relatively empty tram and sat in a corner seat to take a short rest.

But just as he was about to fall asleep, a thought that had almost been forgotten flashed through his mind like lightning, making Uesugi Tetsuya's whole body tremble.

Sleepiness is gone.

He almost forgot!
—This time, he achieved a full 3% historical influence during the Warring States period! His own reputation, as well as that of Imagawa Yoshimoto, also increased significantly!

He hasn't even had a chance to see the changes that will result!
Uesugi Tetsu quickly pulled his phone out of his pocket, opened the browser, and prepared to type in the four characters "Imagawa Yoshimoto".

But just as his finger landed on the "Search" option, the phone screen went black.

It shut down due to lack of power.

Uesugi Tetsu: “…”

At this crucial moment when I'd already taken my pants off, my phone suddenly ran out of battery and shut down.

Actually, shutting down the device now is quite reasonable.

Because he hadn't charged his phone in ages, and even though he kept it in his storage bag when he wasn't using it, taking it out these few times still required a lot of power.

The key is this timing.

It's too tightly locked.

Uesugi Tetsu gritted his teeth unhappily and retracted his fingertips, which were crackling with sparks of lightning.

—Never mind, it won't take much time to find a place to charge my phone.

If you accidentally break your phone, it'll be a real problem; you don't know how much data you'll have to recover.

Let's get off at the next stop.

As Uesugi Tetsu thought this, he kept staring at the timetable on the train and tapping on the slightly cold stainless steel handrail.

Until a gentle yet mechanical female voice rang out.

"Next stop, almost here..."

Chi Chi.

The tram slowly came to a stop, and the somewhat old doors opened to both sides.

Once everyone in line to get off the train had disembarked, Uesugi Tetsu stood up from his seat and walked towards the door.

"Uesugi-kun, is there something urgent that you need to get off at this stop?"

The voice, so familiar it was almost unbearable, stopped him in his tracks.

Uesugi Tetsu looked up and, in the somewhat blurry sunlight, saw a girl with black hair and a high ponytail, who had a calm demeanor and dressed in a very common style.

A simple, oversized long-sleeved white T-shirt paired with cropped jeans. Nothing more.

She was also looking at him with one hand in her pocket, as if he had run into a good friend, so he casually struck up a conversation.

The tram's imminent departure bell spurred the girl to step inside.

The two looked at each other silently.

Uesugi Tetsu took a deep breath, as if he had made a momentous decision.

He turned to Ririko and asked her the first question he had after their long separation.

he asks,

Do you have a power bank?

Even with Ririko's calmer state of mind than Walden Pond, a look of surprise appeared on her face at this moment.

……

"So, you want to get off at this stop and asked me for a power bank just because your phone is dead?"

"Completely correct."

They returned to their original corner seats and sat side by side.

In Uesugi Tetsu's hand, he was holding the girl's phone.

"What era are we living in? You can still turn off your phone when you go out."

Having just finished instructing a certain otaku girl, Ririko looked away, crossed her legs, and muttered, "Uesugi-kun, you're probably going to need to hire a master at home..."

Opening Ririko's phone reveals an exceptionally simple interface.

Aside from essential chat, social, and information apps, not a single entertainment app was installed.

From the side, Ririko's slightly curious voice came.
"What are you looking for?"

"A little history."

"Oh."

Ririko lost interest, so she rested her cheek on her right fist and quietly gazed at the scenery rushing past the car window.

After not seeing each other for a few days, Ririko actually had a lot to say to Uesugi Tetsuya.

But after seeing her on the tram, she realized there was no need to say much.

The girl raised her hand and gently twirled the silk threads that were floating off Uesugi Tetsuya's body.

This principle of swordsmanship is the best answer.

"Skill and reason..."

To her left, Uesugi Tetsu once again typed "Imagawa Yoshimoto" into the search box.

Click search.

Then click into Yoshimoto Imagawa's Wikipedia page.

Uesugi Tetsu read down line by line, word by word, only to find that the encyclopedia recorded that Imagawa Yoshimoto was still defeated at Okehazama.

The key historical junctures remain unchanged.

But it shouldn't be.

He minimized the losses to the Three Rivers Kingdom, and she took the opportunity to seize real power over all the local powerful clans in the Three Rivers Kingdom. She even made preparations in advance before the world was restored.

Moreover, having been through so much with Imagawa Yoshimoto, it's unlikely he would make the same careless mistake again.

Uesugi Tetsu scrolled up and saw the information about the 1556 Mikawa Uprising, which was suppressed at an absurd speed.

This proves that his changes to history were real.

"Strange thing..."

Instead of exiting the page, Uesugi Tetsu opened an incognito page and searched for "Sengoku Dai Onmyoji Tetsu".

Since his reputation during the Warring States period exceeded 8000 points, the records must be much more detailed than before...

No relevant search results found.

A blank search page popped up on the phone screen, startling Uesugi Tetsuya.

Scrolling down, you can only find a lot of related searches for Onmyoji, but there is no one named "Great Onmyoji Che of the Warring States Period".

Not a trace.

It's as if it never existed.

After searching repeatedly without success, Uesugi Tetsu returned to Imagawa Yoshimoto's encyclopedia page.

Then they discovered that the text above, describing his use of thunder magic during the coming-of-age ceremony, had also disappeared.

Uesugi Tetsuya remained silent for a moment.

How could this be?
Hasn't your reputation skyrocketed many times over?

Then how come you can't find anything at all?

It doesn't make sense.

"Still looking? What are you looking for?"

Ririko turned her head and poked his calf with her toe.

Uesugi Tetsu stared at the now much longer encyclopedia entry for Imagawa Yoshimoto for a while, then asked, "Ririko, do you know Imagawa Yoshimoto?"

The girl blinked, thought for a moment, and then replied, "Oh...I think I've heard of it."

"—She was a daimyo from the Warring States period, right? She was quite famous."

Uesugi Tetsu's eyes brightened slightly as he heard Ririko casually say, "I remember he was a nemesis who fought the Sixth Heaven Demon King to a standstill."

"—It is said that he died of illness halfway through the Battle of Okehazama."

"You actually know about this? You're a genius history girl."

Just as Uesugi Tetsu was about to nod, he realized something was off about Ririko's words.

Died of illness?

His thoughts froze, and a chill ran down his spine.

Imagawa Yoshimoto had already mastered the breathing technique to the point of circulating vital energy and was about to build his own physical palace. How could he have died of illness?
Ririko snorted softly upon hearing this: "After that Demon King Oda went to attack, he discovered that Imagawa Yoshimoto had actually died of illness in the main camp."

She shrugged: "Please, even a three-year-old knows this kind of famous historical event perfectly well, okay?"

Uesugi Tetsu didn't hear what she said after that; he just kept thinking to himself.

Died of illness.

This word inevitably reminded him of the curse he had uttered before his death from illness.

Uesugi Tetsu remained silent.

What happened in the four years after he left?

Was it because he chose the wrong time to leave?
And there's one more crucial point.

—If even a three-year-old knows the name Imagawa Yoshimoto, does she currently exist in the world of the living?

A myriad of thoughts flooded Uesugi Tetsuya's mind, swirling together in a chaotic jumble.

Until his phone was snatched from his hand.

Ririko patted his back forcefully, startling Uesugi Tetsuya.

"It's time to get off, Uesugi-kun."

The girl raised the hand holding the phone, and a soft voice came from in front of her.

"Got home."

Uesugi Tetsuya finally snapped out of his daze and stepped off the train as if waking from a dream.

—Hearing footsteps from behind, Ririko also turned her attention to the screen on her phone that was still open.

The girl glanced at Imagawa Yoshimoto's incredibly complex encyclopedia entry, raising an eyebrow in disbelief: "When did he become such a history buff...?"

You should know that Uesugi Tetsuya used to never care about history and knew nothing about related knowledge.

If a three-year-old child knows that Imagawa Yoshimoto died of illness in Okehazama, then he is not even as good as a three-year-old.

Moreover, how could simply looking at an encyclopedia entry possibly lead him into such deep, oblivious contemplation?

Lili narrowed her eyes.

Her sword heart stirred slightly, telling her that there must be something fishy going on here.

Not long after, the two returned to the villa.

Uesugi Tetsu, who hadn't seen his familiar home in a long time, was about to take Kaka out of his backpack when he sensed the omnipresent... Kenji?
Uesugi Tetsu turned his head and looked around at the "Sword Principle" that covered an area of ​​dozens of meters.

No, this should be called a sword domain...

Ririko's Sword Domain.

He hadn't noticed it before when he was focused on historical issues, but now he could feel the sword domain that he had never been able to grasp before.

But it was only barely "visible".

It's probably because he's only just begun to understand swordsmanship.

Ririko opened the door with practiced ease, and Uesugi Tetsu followed her into the empty dojo.

He was about to ask about the relationship between technique and principle when he heard Ririko snap her fingers and say...

"How about we have lunch first?"

Uesugi Tetsu opened his mouth, then swallowed back what he was about to say.

He then nodded and smiled.
"Alright."

It's been a long time since I've had a meal cooked by Ririko.

Ririko waited for several seconds, and after realizing that he hadn't thrown out the Second Master, she asked again.

How many bowls would you like?

Two bowls are enough.

Meeting Ririko's gaze, Uesugi Tetsu's smile froze for a moment: "Lord Nisha... well, she's encountered a small problem."

Ririko was slightly taken aback, but didn't ask any further questions.

She simply looked at the corner that had been bustling and lively, but was now completely empty.

Just a few days ago, the two-foot-tall man was here with her, striking the samurai Zanzemaru together.

The girl turned back without a trace and walked upstairs, her intermittent voice carrying from the stairs into the empty dojo.

"I'll go cook now, it might take a while since I didn't prepare in advance..."

Uesugi Tetsu replied with an "okay," watching her figure disappear.

"Is it taking a while?"

It's perfectly normal to do some light exercise before lunch so that you can eat more later.

Leaning back under the large character "武" (martial arts), Uesugi Tetsuya held the azure star in his hand and took out the fragments of the Totsuka Blade.

He closed his eyes and looked inward at the empty sea of ​​qi, which was much larger than before.

Because the initial area was very small, the gas sea expanded rapidly.

In just a few days, it has grown by about half again.

It's important to know that the Warring States period was affected by a time flow rate of 15 times.

Within the expanded Qi Sea, the Four-Tailed Fox card had already occupied the high ground, filling about two-thirds of the entire Qi Sea, squeezing the White Prajna card's survival space to the brink of collapse.

Uesugi Tetsu thought with some confusion, "They are clearly of the same quality and have the same star rating."

But he quickly put the problem aside.

Thinking too much is pointless; there's just too much he doesn't know about the Qi Sea.

What needs to be done now is to test whether these fragments of the epic-level Ten-Fist Sword can become one of the five elements defining elements in his empty Qi Sea!

Using his inner energy to tightly envelop the fragment, Uesugi Tetsuya attempted to send it into his dantian along with his inner energy.

Soon, with a pop, the protective energy and the fragments of the Ten-Fist Sword went in together.

It worked!
Uesugi Che exclaimed.

He hadn't expected it to be so simple.

The next moment, a clear warning message jumped into Uesugi Tetsuya's consciousness.

[Attention! You have placed "Potential Boundary Material: Fragments of the Totsuka Sword" into the Void Qi Sea!]

Should it be considered the sole defining characteristic of an empty sea of ​​qi?

In that instant, the layers of qi that enveloped the fragments of the Ten-Fist Sword dispersed, revealing the fragment that was floating above the sea of ​​qi, radiating dazzling golden light!

In an instant, both the originally arrogant Four-Tailed Fox card and the White Prajna card, which was already at the bottom, were firmly pressed down to the very bottom.

Therefore, Uesugi Tetsu was able to perceive it clearly.

If he were to choose now, he would use the fragments of this Totsuka Sword as the sole defining element to define his Void Qi Sea.

Then his dantian could expand instantly, increasing in size by dozens or even hundreds of times!

Then, it becomes the premier metal-type Qi Sea!
It's even possible that some mysterious forces related to Susanoo or Yamata no Orochi will appear in the Qi Sea!
