I became the Lord of the Eternal World in Tokyo.

"Even if they know my strength, what can they do?"

Uesugi Tetsu calmly clenched his fist, pure white qi and tiny sparks of lightning dancing between his fingers.

So-called conspiracies and tricks can be shattered with a single punch.

He walked into the room without a word, took a deep breath after closing the door, and immediately felt his thoughts become lighter.

Refreshing!

In the very center of the room, an unlit requiem candle stood quietly, continuously emitting a refreshing fragrance.

Beside the incense and candles for soothing the soul, a crystal-clear Five Thunder Pearl was placed on a piece of red silk cloth.

Uesugi Tetsuya then took out the "star" from his pocket, which he had tied with silk thread to make into a necklace, and hung it around his neck.

He took off his thin clothes, jumped into the black liquid in the wooden tub, and then, as usual, swallowed the ash from the calming incense.

With these five buffs, it would be difficult for cultivation speed not to be fast!

Uesugi Tetsu glanced one last time at the two skills whose proficiency would be improved.

【Corona Breathing Technique (Skin Tempering 336/360)】.

【Five Thunder Techniques - Qi Harmony (Proficiency 579/1400)】

The skin tempering was just one more step away, and in the past few days, my proficiency with the Five Thunder Technique had also increased considerably.

However, the Natural Mind-Body Flow has been somewhat neglected these past few days, only swinging the sword to maintain its feel, since the breathing technique is about to reach an important stage of advancement.

As for spirit control techniques, Uesugi Tetsuya tried to practice them in his spare time, but he gave up after only gaining 1 point of proficiency each time.

It can only be said that the Yin-Yang arts of the Warring States period were truly inhuman.

Even someone whose spiritual energy absorption speed is hundreds of times faster than that of an ordinary person is like this, let alone ordinary cultivators...

Uesugi Tetsu closed his eyes, banishing these distracting thoughts from his mind, and instead embraced the burning pain.

—This time, I absolutely must complete the skin tempering!

……

Outside the room, Erchi was sitting in the corridor protecting Uesugi Tetsuya, idly swinging her legs and teasing the little sparrows that flew onto the back of her hand and the white hat on her head.

With the aura of friendliness, the relationship between the two-foot-tall adult and these small animals in nature progressed incredibly quickly.

Shiraishi pressed his ear against the wooden board and heard the sounds coming from inside the room with perfect clarity.

Just listening to it from outside made his face twitch and his legs feel weak.

Bai Shi asked in a low voice.

"Little Boss, will he die in here...?"

The two-foot-tall man gave a faint, cold snort.

"What are these? Lord Che's willpower is so strong that it's beyond the imagination of a little kid like you."

She didn't actually like Shiraishi very much.

Because Erchi always felt that Baishi was glib and never did anything productive. He not only didn't help Shangche, but often dragged him down.

Unlike me, who always thinks of Lord Che, even if there are things I can't help with, I will go back to the Ksitigarbha statue and try not to cause trouble.

Two hours flew by.

This amount of time was nothing to the two-foot-tall man who had been alone for over a hundred years; it passed in the blink of an eye.

Instead, Shiraishi couldn't resist taking out his ninja manual and starting to practice.

Wow.

Some of the heavy sliding doors were pulled open in an instant, and a large amount of white, hot steam rushed out of the room, startling away the small animals beside the two-foot-tall man.

But the girl didn't mind; she immediately turned her head in surprise.

"Master Che!"

Hearing the commotion, Shiraishi looked curiously into the billowing steam.

The autumn wind blows.

The steam slowly dissipated.

Then, both of them were stunned.

As the steam dissipated, a handsome man with jade-like skin was revealed to them.

The shirtless man slightly twisted his neck, allowing the afternoon sunlight to fall on his smooth, white skin, giving it a luster like that of marble, revealing the pure beauty of his flesh.

"call--"

Uesugi Tetsuya exhaled the intense heat that had been absorbed by the air, and stretched with great ease after feeling the coolness of late autumn.

Feeling the gentle breeze on his face, Uesugi Tetsu lowered his eyes to look at the large number of prompts that suddenly appeared in front of him—

[Your skill, Coronal Breathing proficiency +26! ]

[Your skill, Five Thunder Method: Qi Combination Proficiency +6!]

[You have completed the Flesh Palace Training - Skin Tempering Stage!]

Your skin strength has increased moderately!

[Your physique +3! ]

[Because you have completed the "Skin Tempering Stage," your efficiency in utilizing Qi has slightly increased!]

Although the path of cultivation is painful and slow, the skin tempering stage has finally been completed!

Originally, this skin tempering required a full 1500 points of proficiency to complete, which is almost equivalent to half the proficiency required to advance the Corona Breathing Technique from the proficient level to the master level.

But with the help of a variety of factors, it was actually completed in just a few days during the Warring States period.

Converting this amount of time into reality...

Uesugi Tetsuya's thoughts paused slightly as he realized that he had been so engrossed in his cultivation these past few days that he had forgotten to check the flow of time on both sides.

Okay, let's finalize this before we leave the Imagawa House.

Thinking about it, Uesugi Tetsu casually brought up his attribute panel—he hadn't really looked at this thing properly in a long time.

【Uesugi Tetsu (Four-tailed Fox Incarnation)】

【Physique: 51】

[Will: 31]

【Charm: 12 (21)】

[Spiritual Skills: 79]

Oops.

I haven't checked in a long time, and I was surprised to find that my physical attributes had already exceeded 50 without wearing the Prajna Mask. If I were to wear the mask again, I could easily break through the 70 mark.

"This is really unexpected."

Uesugi Tetsuya exclaimed inwardly.

If he continues to progress at this rate, it might not be long before he can go back to Edo Castle and spar with the wax figure that once killed him in one blow.

For the other party, it probably hasn't been many days.

Just thinking about the possible expression on the wax figure's face made Uesugi Tetsuya's lips curl into a slight smile.

Finally, there's the newly popped-up proficiency panel for the next stage, "Bone Forging."

Ririko is currently in the bone-forging stage, but it's unclear exactly how far she's progressed.

But no matter what, I'm sure I can surprise her when we meet again.

[Coronavirus Breathing Technique (Hard Bone 2/600)]

[Effect: Upon reaching perfection, bones become as hard as wood.]

—Skin forms the outline, bones form the support.

"Even with a 10% reduction, it's still 600 proficiency points, which is slightly more than skin tempering."

Uesugi Tetsu thought it might be an effect of completing the Nine Breathing Techniques earlier.

After closing the last panel prompt, Uesugi Tetsu turned his head and saw the two little ones sitting and lying on the corridor, staring blankly at him.

Completely oblivious to his immense charm, Uesugi Tetsu raised an eyebrow: "Is there something dirty on me?"

Seeing that the two little ones were still in a daze, and that the adult was even drooling, Uesugi Tetsu realized that his current attire seemed rather "revealing".

"I'll take you out later, but you need another half hour to consolidate your newly broken-through realm."

After saying that, he turned and went into the room, closing the door behind him.

After quickly tidying up the buff items in the room, Uesugi Tetsu took out the [Key of History - Shrine], closed his eyes, and returned to the present world.

Then, after glancing at the time on his phone, he was transported back to the Warring States period.

The two-foot-tall man outside sensed the sudden change in his heartstrings, blinked, and then understood what Uesugi Tetsu was doing.

So she turned her attention to Shiraishi beside her, ready to stop him from entering the room at any moment.

Half an hour passed in the blink of an eye.

Uesugi Tetsu, who once again traveled back and forth between the Warring States period and the present world, confirmed one thing.

That is, the flow of time in the Warring States period has changed compared to the present day.

It's no longer 30 to 1.

Instead, it was reduced by half, becoming fifteen to one!

"Fifteen to one..."

Uesugi Che frowned slightly.

After a long while, he breathed a sigh of relief.

Although the time flow rate was halved, it didn't actually have a significant impact on most of his plans.

If the flow of time were to drop to less than five to one, he probably wouldn't be able to maintain his current leisurely pace during the Warring States period.

"However, we really don't have enough Soul Ash."

Uesugi Tetsu looked at the amount of Requiem Incense Ash that had once again run out and the remaining 567 points of Soul Ash.

This amount of Soul Ash is not enough for a ten-pull, nor enough to summon Sheng Hai or open the next special card pool, and it's even a bit difficult to maintain the daily training expenses.

—Compared to the powerful demons causing trouble in the Three Rivers Kingdom, who are not even close to him yet, it is more realistic to find a well-known supernatural location in the mortal world and obtain soul ashes from there.

As for Edo Castle... Uesugi Tetsu didn't really want to enter it until he had at least the strength to kill a three-and-a-half-star demon samurai like Hakubura.

Ever since he entered Edo Castle, Uesugi Tetsu had always felt a ghostly gaze watching him.

This is not a good sign.

Furthermore, the advancement of the two incarnations, White Prajna and the Four-Tailed Fox, will likely not be completed until after the Mikawa Kingdom incident.

Therefore, Uesugi Tetsu wanted to improve his strength as much as possible before encountering the unknown great demon.

Even if a map from the Warring States period is only three stars high, those who might be called "great demons" are invariably either powerful individuals or have outstanding talents in a particular area.

Therefore, it's always good to have a backup plan; having more Soul Ash on hand gives you more options.

but now……

Uesugi Tetsu opened the sliding door, looked down at the two children whispering to each other, their relationship seemingly having suddenly improved, and said...

"Let's go out and try cutting the earth."

Bai Shi and Er Chi exchanged a glance, cheered, gave each other a high five, stood up, and followed behind him.

Uesugi Tetsuya took out Kaga Kiyomitsu and wore it at his waist beforehand.

This time, he didn't plan to let Erchi continue carrying the sword. The child had finally gone out for a stroll, so he wanted to make things easier for her.

Not far from the entrance of the Imagawa-kan.

Imagawa Yoshimoto frowned, slowly tapping the stiff-bristled brush in his hand, formulating a general strategy for suppressing Mikawa Province based on the details narrated by Hanzo beside him.

Since returning to the Imagawa Mansion, Okabe Motonobu, who was inseparable from the head of the household, glanced at Uesugi Tetsuya, who happened to be passing by at the edge of his field of vision, and exclaimed in surprise, "Oh!"
