I became the Lord of the Eternal World in Tokyo.

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!

Chapter 207 Soul Ashes Surpass 10,000 for the First Time! The Limitless Potential of the "Lin" Technique! Arakawa Village No Longer Exists.

The strength of using the fragments of the Totsuka Sword as the sole boundary of the Qi Sea is not low, and its future potential is also not low.

Because it is part of a mythical weapon.

Uesugi Tetsu could easily collect more fragments of the Totsuka Blade in the future, or even a complete Totsuka Blade, to complete the boundary marker.

Defined by a single Ten-Fist Sword, it is certain that it can create a vast sea of ​​qi that is among the most powerful and deadly in the world.

So, how do you choose?

Uesugi Tetsu gave the answer without hesitation.

"How can we be so short-sighted as to abandon the greater for the lesser?"

With a flick of his finger, he erased the "unique defining object" notification from his eyes.

Indeed, the prospect of instantly converting potential into strength and expanding one's Qi Sea by tens or hundreds of times is very tempting, and a clear path to advancement in the future is laid out before one's eyes.

However, this would mean losing its true potential.

For Uesugi Tetsuya, what is "true potential"?

"Demon Incarnation Cards"

There is no doubt about this.

Even his desire to define the Qi Sea using the Five Elements was due to the incompatibility between the two incarnation cards within the Qi Sea.

—The potential of establishing a stable cycle by defining objects based on the Five Elements, and then placing five avatar cards whose rank can be continuously increased within it, is simply immeasurable.

And currently...

Uesugi Tetsu stared at the fragments of the two avatar cards that were suspended in the air, ruthlessly suppressing them.

Hmm, the fragments of the Totsuka Blade don't seem to fit in very well with them.

Perhaps the moment it is confirmed as the unique defining element, it will kick both cards out of their dantian with a powerful flying kick.

This is something Uesugi Tetsuya didn't want to see.

"So, go down."

Uesugi Tetsu said softly, manipulating the qi generated by the cards within his dantian, forcefully pulling the fragment into the churning dantian.

The debris struggled for a moment, but was quickly engulfed by a large amount of gas.

As if knowing his thoughts, a second notification popped up—

Should the "fragments of the Ten-Fist Sword" be considered one of the five elements defining elements of the Void Qi Sea?

"Yes."

Uesugi Tetsu nodded.

The golden light that had enveloped the entire empty sea of ​​energy slowly faded away and instead gathered on the surface of the debris itself.

buzzing.

A moment later, the fragments, which had changed their previous domineering attitude, rose again from the sea of ​​qi, slowly surveying the area as if searching for a suitable avatar card.

Finally, the golden fragments landed on the top of the Prajna card, merging with it and giving the already luxurious card a shiny gold border.

This also caused the white Prajna in the card to move slightly, adding a touch of spirituality to her eyes.

Wow!

In an instant, the Qi Sea, which had been occupied by the four-tailed fox for two-thirds of its area, began to churn violently.

In a short while, the black and red Qi Sea part compressed the large pink and white Qi Sea back, turning the empty Qi Sea back into a scene where each half of it was yours and the other half was mine.

Although the overall portion occupied was compressed, the actual amount of "qi" was far greater than before.

Uesugi Tetsu roughly estimated that after the fragments merged with the Hannya card, the entire empty sea of ​​qi expanded by at least one or two times in a few seconds.

Moreover, it continues to expand at a rate more than ten times higher than before.

Unfortunately, the anticipated connection and cycle were not achieved—the parts of the Prajna and the four-tailed fox remained distinct, each doing its own thing.

"This is normal."

After all, this is something that can only be achieved through the cycle of the five elements, and currently he only possesses one of them in his Qi Sea.

However, it did manage to restrict the Four-Tailed Fox card.

—Moreover, the Prajna card does not have reverse pressure.

In addition, Uesugi Tetsu could clearly feel that the energy in the entire Qi Sea had gained a cold and sharp edge.

This should significantly improve the armor-piercing ability of these qi-based attacks.

Beyond that... there is nothing else.

The fragment was ultimately just a fragment, and Uesugi Tetsu refused to make it the only one, instead making it one-fifth of the defining element.

This is his choice.

Uesugi Tetsu quietly examined the two cards for a while, and nodded with a smile after discovering that they continued to expand peacefully.

He opened his eyes in the temple.

Soon, one can notice that the amount and quality of the internal energy are increasing at a rate that, though small, is clearly perceptible.

Going forward, both the intensity of the Qi circulation and the speed of refining the flesh palace will become stronger and faster.

The noise was exceptionally quiet.

It would be more accurate to say that changes in the Qi Sea have almost no impact on reality.

Uesugi Tetsu slowly exhaled: "Qi Sea, as expected of the noble output that can only be unlocked at the end of the first major stage of the Breathing Technique."

Compared to internal strengthening of the five internal organs and the free flow of Qi to the four corners of the body, Qihai completely surpasses it by countless times in terms of both sheer strength and functionality.

Just then, his nose twitched slightly as he caught a whiff of the aroma of bone broth wafting down from the third floor.

"Ririko, what are you doing? It smells so good..."

As Uesugi Tetsu wiped his mouth, he remembered what Ririko had said before: cooking is also a form of spiritual practice.

—It's Sword Principles, I added Sword Principles!

"Okay, no matter how outrageous the answer is, it shouldn't be this."

He listened intently to the sounds coming from upstairs and realized that there was still quite a bit of time before the meal was finished.

"Then let's take this opportunity to learn the nine-syllable mantra as well."

Anyway, all you need to do is tear open the scroll.

Uesugi Tetsuya took out a scroll from his storage backpack and examined it briefly. This ancient scroll contained one of the legendary Great Yin-Yang Techniques, the Nine Syllable Mantra.

Judging from its appearance alone, the scroll's value is completely unknown.

—An old, dusty, tattered scroll of unknown material, with blurred writing on it, making it impossible to appreciate its mystique.

Even Uesugi Tetsu is the same.

At first glance, all he saw was a piece of trash that had been found somewhere.

It must be said that a scroll containing the Great Yin-Yang Technique is extraordinary.

Uesugi Tetsu nodded noncommittally and exerted force with both hands.

tear--

The sensation felt on my hands wasn't the fragile feeling of tearing paper.

Rather, it is so strong that even the edges are not damaged in the slightest!

Ok?

Uesugi Tetsu raised an eyebrow, and a tangible aura immediately enveloped his palm.

Once again, exert all your strength from the center outwards to both sides!

wrong password.

The parchment scroll remained completely still.

Despite its apparent appearance, the reality is that even with all his might, Uesugi Tetsu couldn't tear it apart even a little bit.

"Perhaps... it's to prevent it from being torn apart by ordinary people or samurai who only practice breathing techniques."

The thought flashed through his mind, and Uesugi Tetsuya acted on it immediately.

Thus, the protective aura disappeared, replaced by a thick, almost liquefied spiritual energy that enveloped the body.

The immense spiritual power that had just flowed from Uesugi Tetsuya's hand was completely absorbed by the parchment scroll.

Uesugi Che's eyes lit up.

correct!

He grinned and immediately increased his spiritual energy output, wanting to see how much spiritual energy it would take to feed the little parchment scroll in his hand.

Ten seconds, twenty seconds...

After a minute, Uesugi Tetsuya, in his human form, was covered in sweat and his spiritual energy was almost depleted, so he had to transform into a four-tailed fox to continue.

Feeling his spiritual energy replenished once more, Uesugi Tetsu gripped the parchment scroll tightly and activated his Spirit Control Technique with all his might, absorbing the spiritual energy of heaven and earth while pouring it into the scroll.

Upstairs, Ririko, who was holding the handle of the pressure cooker that she almost tipped over, frowned.

—What is Uesugi-kun up to down there again?
