I became the Lord of the Eternal World in Tokyo.

Although his inner energy and mental strength were completely depleted, he narrowly escaped death in a very short, almost immeasurable amount of time.

Furthermore, he successfully plucked a piece off that demon-level eyeball using the Nameless Sword!

Exhausted, Uesugi Tetsu glanced at his storage backpack out of the corner of his eye and said in a low voice, "Let's go outside first. It's not convenient to talk here."

Seeing his appearance, Tamamo and Yagyu Akira had no suspicions. After Uesugi Tetsuya struggled to his feet, they quickly headed towards the tunnel exit.

The road we came on was clear, with almost no demons blocking our way.

The few remaining spirits that appeared were quickly dealt with by Kaga Kiyomitsu and Yagyu Akira.

In less than half an hour, the three of them returned to the tunnel exit and saw the sun already high in the sky.

A gentle warmth poured down, dispelling some of the unease in Tamamo's heart.

She first confirmed once again that the Special Affairs Department's recovery vehicle was on its way, and then took out the barrier scroll from her bag and tore it open.

An integrated early warning and defense barrier was deployed.

At this moment, Tamamo turned to Uesugi Tetsu, who looked visibly exhausted, and asked again, "Brother Uesugi, what was inside just now?"

Uesugi Tetsu sat on a rock, pinched the bridge of his nose, and thought that this was a good opportunity to reveal all the information about the factory.

So he began with the briefest, yet most important, piece of information.

"At least tens of thousands, with no upper limit, of bio-mechanical units ranging from half-star to one-star from the Changshi Factory, and an eye that is not weak even among the Ghost God level."

Tamamo, who was about to take notes, paused, her fingers hovering above the keyboard for a long time without falling.

Gulu.

Tamamo's lips turned pale.

She looked at Tsutomu Uesugi, and then heard him repeat it word by word.

Immediately, Tamamo wanted to collapse and everything to go black, hoping that someone would wake up and tell her that it was all a dream.

However, Tamamo's excellent professional skills made her think more calmly and clearly, and she typed every word truthfully on her phone.

She asked in a hoarse voice, "Is there anything else...?"

Uesugi Tetsu continued speaking, revealing everything.

Hearing these words, Yagyu Akira, who was standing to the side, tightened his grip on the hilt of his sword.

"Now, who knows how many more colleagues will die..."

five minutes later.

"Report it first!"

After confirming that everything was correct, Tamamo stamped all the documents with a blood-red "Top Secret" seal.

The document was then divided into three parts and sent to the Shizuoka Prefecture Special Affairs Office, the Arakawa Ward Special Affairs Office, and the Five People's Association's mailboxes respectively.

After finishing her work with utmost care, the petite girl collapsed to the ground.

She cursed fiercely in a Kansai accent, "This is fucking terrifying! We almost died a horrible death!"

"Damn, there's been so much crap going on lately."

Tamamo hugged her knees, resting her chin on them, and muttered as if reciting a familiar list: "It's the Sengoku Mystic Realm phenomenon again, the Tokoyo Train, and all sorts of urban legends reviving one after another, and now there's this Tokoyo Factory Owner..."

She grabbed her hair, looked up to the sky, and screamed.

"Ugh! This is so annoying!"

Upon hearing the keywords, Uesugi Tetsu didn't ask directly, but instead opened the Edo Castle gacha page.

—The Hundred-Eyed Demon had already eaten the two eyeballs he had thrown in earlier, and now the progress bar above its head had reached [86%].

Uesugi Tetsu then turned his gaze to the palm-sized fragment of the eyeball that he had just desperately scraped off...

Or perhaps the outer skin of the eyeball is a more appropriate term.

Since it's just the outer skin of a demon-level being, it's not really an item or material, so no interface pops up on it.

I wonder what surprises it might bring me.

With a slight thought, Uesugi Tetsu threw the small fragment in front of Hyakume.

Then, Uesugi Tetsu saw the Hyakume-ki loli standing there, staring at her intently for a long time before finally showing a shocked expression for the first time.

In the blink of an eye, the progress bar, which was previously at 86%, was filled.

Hyakume-ki's ascension has begun.

Chapter 214 The Gamble Between Yagyu Dojo and the Sengoku Daimyo! Slashing Expert Kakashi! Making Up for Insufficient Battle Rewards

What followed was a completely opaque, black and red giant cocoon that wrapped the Hundred-Eyed Demon Loli layer by layer.

Airtight.

Uesugi Tetsuya was stunned and hadn't reacted yet.

Several seconds later, the full progress bar disappeared, and from any angle, all that could be seen was that breathtaking black cocoon.

He then realized that Hyakume had entered a state of advancement.

—These eyeball fragments are far too potent.

It was truly worth risking my life to provoke that ghost-level eyeball, which most likely belonged to the factory owner's faction, with the Nameless Sword.

Although it seemed that the last big eyeball remembered her...

But who knows how long it will take before the actual eyeball is allowed to enter the mortal world openly and legitimately.

Uesugi Tetsu sneered inwardly.

By then, it will be unclear who will be hunting whom.

He sat on the rock, staring at the black cocoon standing on the ground for a long time, but did not notice any visible changes in it.

"It seems that this quality upgrade will take much longer than the last one."

Thinking of this, Uesugi Tetsuya turned it off first, then looked at Tamamo, who was casually slumped over scrolling through her phone, and asked as if nothing had happened.

"Tamamo... could you explain in detail the 'Warring States Secret Realm Phenomenon' you just mentioned?"

"Huh?"

Tamamo stopped swiping her phone screen, pulled her legs back, and muttered, "I didn't expect Uesugi-nii to be interested in the Warring States period."

Uesugi Tetsu countered, "Aren't the minority the ones who aren't interested in the history of the Warring States period?"

“People like Oda Nobunaga, Toyotomi Hideyoshi, and Imagawa Yoshimoto are all figures that any elementary school student would know.”

"That's true."

Tamamo stuck out her tongue and retrieved the relevant memories from her mind: "That so-called Warring States Secret Realm seems to be something like a ghost story—as long as it is not removed, it will keep generating Warring States soldiers at the same time intervals."

Moreover, this trend is becoming increasingly stronger.

Uesugi Tetsu pressed further, "How do we get rid of them? And what were the identities of those Sengoku soldiers?"

"We don't know about that."

Tamamo helplessly spread her hands: "This is not within our scope of work, so of course we can't get more detailed information and intelligence."

Uesugi Tetsu nodded, thanked her, and secretly memorized this "Warring States Secret Realm" in his heart.

He had just done some research while Tamamo was speaking and found that Shizuoka Prefecture during the Sengoku period was Suruga, Tōtōmi, and the Izu region.

In other words, it was an ally of the Imagawa clan, with the majority belonging to the Imagawa clan and a smaller portion belonging to the Hojo clan.

Now, things have become a bit complicated.

Could this hidden realm from the Warring States period be related to the Imagawa clan and Imagawa Yoshimoto...?

Uesugi Tetsu tapped his knee with his fingers, trying to search for more relevant information online.

But even when the special operations vehicle that Tamamo had called arrived, Uesugi Tetsuya still found nothing.

"But it's normal that this kind of information can't be found online. In the Special Affairs Department, it would at least be classified as confidential information."

Uesugi Tetsu wasn't too discouraged and finally got into the recovery vehicle that seemed to be cut from the same mold as the one in Arakawa Ward.

He touched the thick steel walls of the vehicle and sighed, "The last time I rode in this vehicle was after I killed the Nue from the Demon Guide Association."

Yagyu Chi gave a soft "hmm," looking puzzled.

Sitting diagonally opposite, Tamamo's expression twitched; she clearly knew what the words "Demon Guide Association" represented.

"What a formidable person..."

The petite girl, who slumped down but whose feet couldn't even reach the bottom of the seat directly opposite her, couldn't help but complain.

Once the rear doors were completely closed, Tamamo slowly spoke up: "Brother Uesugi, may we talk about your work here now?"

While investigating how his spiritual energy had recovered by more than half in just a few minutes, Uesugi Tetsuya turned his attention to her and nodded.

"Just tell me."

Meanwhile, he was still pondering in his heart, puzzled – why did his spiritual power suddenly increase by nearly 20% when it could only recover to half its previous level?

The quality of Qi in the Spirit Control Technique did not increase, and the increase in the concentration of spiritual energy in heaven and earth was only one or two points, which is negligible.

This is a very strange question.

Moreover, it seems that it only appeared recently after returning to the present world from the Warring States period.

"Then, Brother Uesugi, please sign the confidentiality agreement first."

Tamamo casually pulled out a general confidentiality agreement from the Special Affairs Department, and then used a pen to write the unique number of the mission related to Uesugi Tetsu in the "Number" column in the lower left corner.

There was a snap.

The mysterious and profound spiritual energy fluctuations began with that simple line of numbers and spread, enveloping the entire sheet of white paper.

The confidentiality agreement, which was originally just a piece of plain white paper, suddenly changed into a blood-red leather scroll.

"what?"

Tamamo's hand holding the confidentiality agreement trembled violently: "Holy crap, Uesugi-nii, how come your confidentiality level is so high!?"

Blood red usually represents files or intelligence classified as "Secret" in the Special Affairs Department.

It was also referred to as a "red letter" by intelligence and document-related personnel.

This means that once a secret is leaked, the Special Affairs Bureau will launch an endless manhunt for the target, and only blood can wash away the act of leaking information.

Would a regular seed have this level of confidentiality?

A hundred thousand brilliant ideas flashed through Tamamo's mind in an instant.

The person who turned the white paper red took the paper and pen, puzzled, and tapped the bottom right corner: "So, I can just sign my name here?"

Tamamo stood there for a while before quickly starting to peck at the rice like a chick.

"Yes, yes! That's right!"

Uesugi Tetsu signed his name.

After Tamamo stiffly signed her name, Uesugi Tetsuya could feel a fleeting, subtle fluctuation rise and then disappear.

Although I don't know the specific effects of this confidentiality agreement, I feel that it won't have a significant impact or restriction on me.

Also... judging from Tamamo's reaction, her personal information seems to be very important?

Uesugi Tetsuya was a little confused.

Previously, Yuan Jingshui had opened his box in detail, hadn't he? This is how the Special Affairs Department does its secrecy work.

Or perhaps the Special Affairs Bureau is protecting something else entirely...

I don’t understand, I don’t understand.

Since I don't understand it, I'll stop thinking about it.

Uesugi Tetsu looked at Tamamo, who was trembling as she took back the confidentiality agreement, and waited for her to continue.

I could see her take several deep breaths to calm down her Kansai accent, which was about to slip out again – you can't just say things your colleagues don't understand when you're at work.

Especially temporary colleagues.

"Brother Uesugi, your real job here is to help us completely dismantle the [Mumu Lian Maze]."
