I became the Lord of the Eternal World in Tokyo.

Uesugi Tetsu, who had just gotten up, twisted his waist weakly again—once his attributes returned to normal in a few hours, he would no longer have this "morning syndrome".

At that time, no matter what happens, I will be able to handle it easily.

Let's deal with Jia first.

As soon as Uesugi Tetsuya opened his palm, Kaga Kiyomitsu understood perfectly and landed steadily in his palm.

After a night of internal struggle between his left and right brains, he had almost made a decision.

Nowadays, it's not easy to get a lot of Soul Points, and there aren't any strong opponents right now.

and so……

As soon as Uesugi Tetsu opened Kaga Kiyomitsu's panel, the upgrade notification for the new effect [Plague] popped up in front of him.

The next enhancement for the pandemic will require 2000 Soul Points.

It's much less painful than the sorrow of parting, but it still doesn't change Uesugi Tetsu's mind—just like the reason he didn't strengthen "slashing mastery" above.

"Xiao Jia, get ready."

Uesugi Tetsu slowly said to Kaga Kiyomitsu, "It's time to enhance your IQ."

hum!

Kaga Kiyomitsu was jolted, the sound of his sword ringing out as resolute as that of the most steadfast warrior.

[Do you wish to consume 1500 Soul Points to enhance "Spirit"?]

"Yes."

Uesugi Tetsu's thoughts settled.

The more than two thousand Soul Points that were originally there were consumed like water, causing Kaga Kiyomitsu's body to radiate a shimmering silver light.

Buzz!

Kaga Kiyomitsu, as if sensing that something big was about to happen, was very excited and immediately performed a whole set of radio calisthenics in the air inside the room for Uesugi Tetsu.

But soon after, it suddenly went silent.

Then it fell to the ground with a thud and remained motionless.

They are similar to those patients who are already lying on the operating table under anesthesia, but still try their best to stay awake and prove their strong will.

Uesugi Tetsu walked over and weighed Kaga Kiyomitsu in his hand. After finding that there was no movement in the Heartstrings, he put it back into its sheath.

"She's sleeping very soundly. This spiritual strengthening might take even longer than I expected."

But Uesugi Tetsu wasn't in a hurry.

Currently, there is a 15:1 time flow difference between those in the Warring States period.

He has plenty of time!

With Kaga Kiyomitsu leaning against him, Uesugi Tetsu took out some snacks from his storage bag and ate them, thoroughly enjoying his leisurely time off.

Less than two hours later, Uesugi Tetsuya, who was eating Lay's barbecue flavored potato chips, felt his internal energy and spiritual power return like a tidal wave.

Power once again filled every corner of his body.

"call--"

He ate the remaining potato chips in one gulp, then casually tossed the packaging bag back into his storage backpack.

Before, I was always afraid of choking on potato chips, but now I can finally enjoy them.

He stood up and opened his arms to this world, which was objectively no different, but subjectively felt completely transformed.

"Come on, let me see what changes have occurred in the past few days!"

Spirit Control Technique - Qi, roared into action!

In just two seconds, Uesugi Tetsuya easily arrived at a perfectly clear answer.

The revival of heaven and earth will come in five days.

There are still five days left.

This is significantly more than his initial estimate of the number of days.

But Uesugi Tetsu didn't feel any regret.

Because he is not a gambler.

It's good that we can peacefully welcome the revival of the world during the Warring States period.

Uesugi Tetsu smiled, and without cultivating, he simply closed his eyes and sat there, sensing every slight change in the surrounding world.

After all, it was five hundred years ago, a time of great upheaval and change in the world, completely different from today.

This is a rare opportunity.

In the now tranquil Nishio Castle, countless wisps of air flowed through Uesugi Tetsuya's heart.

When I opened my eyes again, the sun was setting.

The sky was pitch black.

[Because you have comprehended the changes in heaven and earth, your proficiency in the Spirit Control Technique - Qi has increased by 500!]

"That was so easy."

Uesugi Tetsu let out a pleasant sigh, once again experiencing the concrete traces of the times within himself.

Just sitting here carefree for half a day can yield a massive amount of expert-level proficiency.

In just a few days, the expert-level Spirit Control Technique - Qi has already completed a quarter of the progress.

Where else would you find such a good thing?

Before Uesugi Tetsuya could finish his reflection, a notification suddenly popped up in front of him.

[Your Kaga Kiyomitsu: The Blade of Parting's effect seven has been enhanced!]

Then came a slight vibration coming from the scabbard beside him.

[Your Kaga Kiyomitsu has gained a new effect—Spirit!]

[Effect Seven: Spirit. The fully awakened spirit, having undergone yet another meticulous refinement, shines even brighter.]

"Huh? The effect name hasn't changed? Then this can be considered a new effect..."

Before Uesugi Tetsuya could finish half a sentence in his mind, he saw the character "灵" slowly turn into a shimmering, three-dimensional silver character under his gaze.

It contrasts sharply with the hundreds of other semi-transparent white characters on the panel.

So that's where the change came from.

That is indeed quite conspicuous.

Uesugi Tetsuya checked the requirements for the next enhancement and found that only 2000 Soul Points were needed.

The increase from 1500 to 2000 points is really not that significant.

That's good news.

Turning his attention away from the Riddler's effects description, Uesugi Tetsuya asked directly, "Jia, has anything changed? What's changed?"

If you can't tell from appearance and introduction, then you'll have to ask "the person in question".

After a brief silence, a small section of the silver-white blade quietly emerged from its sheath.

What followed was a murmur from the heartstrings, as if it were a hallucination.

Yes, yes!

Uesugi Tetsuya stood there, stunned.

It took him a while to realize that what he was hearing in his heartstrings was not "buzzing and talking," but the same normal voice as a normal person!

Wow, the child can talk now!

Although his speech was still very unclear and his words were dry, mechanical, and devoid of emotion, Xiao Jia could actually speak!

This is an absolutely incredible leap forward!

Being able to speak indicates that a person's comprehension and learning abilities are normal.

If we apply that to Gasol, it would mean a massive, huge increase in IQ!

From now on, it's not unrealistic to imagine that Xiao Jia could also learn the Natural Mind Flow and work together with me to achieve a synergy greater than the sum of its parts!

Absolutely, the potential is limitless!

In that case, wouldn't Xiao Jia be ten or a hundred times smarter than those so-called demon swords?

—Legend has it that there is no talking demon sword.

Uesugi Tetsu clapped his hands: "These next few days, Kakashi, you can just follow behind me and observe what everyone is saying. You don't need to go back into your sheath."

Kaga Kiyomitsu immediately began to happily twist and turn wildly in the air.

But it stammered in its heart, "Okay, okay... oh?"

Uesugi Tetsu thought it probably wanted to say "Yay!", but because it didn't say enough, it didn't express its meaning properly.

It's okay, you can learn it slowly.

No one is born with extensive knowledge of poetry and literature.

Suppressing his excitement, Uesugi Tetsu coughed and said, "Apart from that, are there any other changes?"

Immediately, a wisp of sorrowful parting, shrouded in black mist, swept across Uesugi Tetsuya's cheek and landed on the door frame behind him.

This was thrown out by Kaga Kiyomitsu from a distance of several meters.

Not only that.

Uesugi Tetsu could clearly see that after Kaga Kiyomitsu swung his sword many times in the air, a buff called [Fukuzawa] appeared in front of him.

From a third-person perspective, it looks like a faint red aura of good fortune has appeared above his head.

Little Jia... can now control his own effects at will?

"Great, great, great!" Uesugi Tetsu immediately clapped enthusiastically, giving the child full emotional value. "Very good, Jia, you are really amazing!"

Kaga Kiyomitsu then joined in the cheers, spinning around in the air.

pat pat pat.

Familiar footsteps and voices came together.

“Che-jun…”

Upon hearing this, Kaga Kiyomitsu immediately floated behind Uesugi Tetsuya and remained motionless, pretending to be obedient.

Today, Imagawa Yoshimoto, fully clothed, glanced at it thoughtfully, then pretended not to notice and asked Uesugi Tetsuya, "Are you feeling better?"

Uesugi Tetsu nodded: "It's even better than before."

Imagawa Yoshimoto smiled and said, "Congratulations."

After Imagawa Yoshimoto came in and began to remove his armor, Uesugi Tetsu realized that it had been a long time since he had seen the Mountain Whale King.

"By the way, where's Whale Three... Mountain Whale King?"

Imagawa Yoshimoto continued his actions: "After discovering that we could easily wipe out the demons in Mikawa Province, it went straight back to that mountain, Mount Kujira."

Uesugi Tetsu immediately understood.

The Mountain Whale King has gone back to keep Zashiki company again.

Unfortunately, Zashiki will likely complete this round of the Heavenly Craftsmanship Trial and leave in a few days.

Given the nature of the Mountain Whale King, no matter how much Zashiki tries to persuade it, it will probably wait there for a very long time, perhaps even until the end of its life.

This is not good.

I was, after all, a teammate of its for a while, so I'll lend a hand if I can.

Uesugi Tetsu thought for a moment and said to Imagawa Yoshimoto, "If there is an opportunity in the future, please pass on a message to it, Yoshimoto-kun."

He said, "You can only see the Zashiki by going to the Tokoyo. Otherwise, you'll never see it again."

Imagawa Yoshimoto, who was removing his shoulder armor, paused, and a curious voice came from behind him.

"What kind of place is Changshi?"
