I became the Lord of the Eternal World in Tokyo.

【——Bast leather, copper leather, quenched leather. 】

He clenched his palms, which were covered in sticky blood and sweat, and even so, he could clearly feel the huge changes in his skin.

Become softer and tougher at the same time!

It's like a thick membrane wrapped around the original skin.

Although it is not as beautiful and strong as Lilizi's skin, it can easily withstand those unexpected and weaker sneak attacks.

For example, Xiao Yuelan's final poisonous attack in the previous real sword test - if it happened to him now, that attack would not even be able to penetrate the surface of his skin.

Naturally, those deadly toxins cannot flow into the blood.

Moreover, the original skin hardening required 1500 points of proficiency to complete.

Now, it's like paying in installments. With only 600 points of proficiency, I can enjoy some of the effects of complete skin tempering.

And the overall proficiency requirement has also become lower than 1500 points - bronze skin only requires 400 points of proficiency to complete, what about quenching skin?

300 points? Or even lower?

Not bad, very good!

Uesugi Che moved his shoulders and neck, making a rustling sound, just like the skin breathing.

This scene made Lilizi open her mouth slightly.

"Uesugi-kun."

She asked dazedly, "You... have broken through the tough skin and reached the copper skin stage?"

Uesugi Tetsu smiled, but his smile, covered in blood and sweat, looked particularly terrifying: "This is all thanks to your careful guidance, Lilizi."

"Okay...Okay! Uesugi-kun!"

Lilizi didn't care about the stickiness on his body and threw him to the ground. She stared into his eyes from top to bottom, held Uesugi Tetsu's cheeks with both hands and said seriously,

"——As expected, the compatibility between you and me is perfect."

As early as the two of them started practicing, Erchida, who had been sitting obediently beside them, had puffed up his cheeks, like two little balloons about to burst.

——If this flat-chested devil had not really helped Lord Che a lot just now, and Lord Che looked so tired, she would have kicked the devil out of the house long ago!

Uesugi Tetsu blinked and said, "So, can I go take a shower now? I feel uncomfortable with all this sticky mess."

Lilizi let go of his hand after hearing this, and straightened up to sit on his lap: "Then I will prepare a medicinal bath for you. Uesugi-kun, remember to wash and come over."

Uesugi Che stared at the girl's departing back, recalling her burning gaze just now.

He thought that he probably had some understanding of how to transform the clear mirror in his heart into the foundation for entering the Hundred Refinements - the [Heart Embryo].

In the shower room.

The boiling hot water dripped down from Uesugi Che's plump and sharp muscles, falling into the gaps of the cross grid along with the black and red blood and sweat, and after emitting the last bit of steam, it gurgled into the sewer.

The water temperature of up to sixty or seventy degrees was nothing to Uesugi Tetsu at that moment.

After completing the bast stage of training, his resistance to extreme cold or heat has greatly improved.

At least, based on body temperature, water temperatures within 100 degrees Celsius cannot cause much harm to Uesugi Che.

Uesugi Che lowered his head and looked into his own blurry eyes on the tiles.

He thought silently:

——This is different from Lilizi's constant inward and eternal search within herself, which is "seeking within oneself".

If he wants to transform the clear mirror in his heart into a qualified heart embryo, he probably needs to achieve it through repeated "stimulation" from the outside world.

In other words, it means "seeking help from the heaven, earth and people outside of oneself."

Uesugi Tetsu discovered this just now after feeling Ririko's joyful and hot gaze.

After looking into the eyes of Ririkiko, Uesugi Tetsu inexplicably found that a corner of the mirror had become a little clearer.

This is not an illusion.

But Uesugi Tetsu still hasn't quite figured out what this "stimulation" specifically refers to.

Although the way forward has become clear, it is still confusing.

——However, the cultivation of the state of mind is so difficult and demanding that there is no clear path that can be replicated.

If you want to touch the sword heart that is bright enough to enlighten yourself, you must forge your own path from this moment, from this untempered "heart embryo".

"This can be considered as one of the pleasures of boring practice."

Click.

After turning off the hot water, Uesugi Che slowly wiped off the water droplets on his body and hair with the large bath towel placed beside him.

Then, use the corona breathing method to quickly and conveniently evaporate the remaining water on the body surface.

This saves the trouble of using a hair dryer to dry your hair, and clearly illustrates that the practice of breathing techniques to perfection can also be very useful in daily life.

After taking another bath towel and tying it around his waist, Uesugi Che opened the translucent door of the shower room.

Then, as expected, he found Ershaku-sama standing at the door, staring with wide eyes, wanting to see what was going on.

No, maybe it should be called "five-foot-tall man" now.

"Master Che, Master Che! Let me blow dry your hair!"

At this moment, the girl was holding a low-power hair dryer, her eyes full of expectation.

As soon as he finished speaking, Lord Nishaku noticed that Uesugi Tetsu's hair had already been dried by breathing technique.

She blinked, said nothing more, and put down the hair dryer with a look of disappointment. She pointed behind her and said, "The Great Demon King has prepared the medicinal bath. He asked me to call you over after Master Che is done."

Uesugi Tetsu stared at the girl who had turned back into her two-foot form and pondered for a moment.

Maybe, in the future, I can dry my hair directly after taking a shower without using the breathing method?

Anyway, I’m not bragging.

He nodded and replied, "Okay, I'll go now."

Lord Erchi whispered from behind, "Lord Che, can I go too?"

"No."

Lilizi, who had wrapped herself in a towel without knowing when, leaned against the wall and looked at Erchi: "The herbs that make up this medicinal bath are not cheap. Erchi, you won't be able to absorb them without practicing breathing techniques."

not cheap.

Lady Nishaku pouted, thinking of what Uesugi Tetsu had said to her before: "Be frugal and thrifty."

Lord Che has just gone through such a difficult training, and he must be very tired both physically and mentally.

It’s better not to cause him any more trouble.

The girl rarely made a scene and nodded instead of yelling. "Okay then. I'll be waiting for you outside. Just call me if you need anything."

So, in the surprised eyes of the two people, Erchisama walked outside with a small hair dryer in his arms, and his back disappeared after a while.

Uesugi Tetsu and Ririko stayed where they were, looking at each other in bewilderment.

Lilizi: "When have you ever seriously educated her?"

Uesugi Tetsu was confused: "No."

He pinched his chin. "As the saying goes, people grow up in an instant. Although Nishaku-sama is a kaidan shikigami who has lived for over a hundred years, perhaps he has suddenly become sensible."

"——I think she's more likely to take a detour to capture you, her master."

But Lilizi didn't say this out loud.

How Erchi's personality changed and why it changed were other people's family affairs, and it was not her turn as an outsider to point fingers.

"Without further delay, Uesugi-kun, please get into the bathtub."

Lilizi led him into another relatively empty bathhouse. In the middle of the bathhouse stood two wide and deep smooth wooden barrels.

"We can talk about the extra things while we're soaking."

——Uesugi Che looked at the black, unknown, sticky liquid in the barrel that was constantly bubbling with boiling bubbles, and his eyes twitched slightly.

Can this thing be called a medicinal bath?

If you put an ordinary person in there, they will be roasted directly.

This scene is almost like the torture of being cooked in an iron pot.

"Stop looking at it, Uesugi-kun. The longer you look at it, the longer the medicinal effect will evaporate."

In a blink of an eye, Lilizi threw the bath towel aside, and then quickly got into the wooden barrel, leaving only her neck outside the area covered by the black liquid.

Crackling!

A creepy sound like someone being fryed in oil was heard.

She frowned slightly, exhaled twice, and said, "It's different from the medicinal bath in the sauna room before. That was restorative, but this one is specially formulated for physical training and tempering, and it has a certain stimulating effect."

A certain excitement...

Upholding his trust in Ririko, Uesugi Tetsu took a deep breath and stepped into the bathtub.

The next moment, a burning sensation as if I had really stepped into a boiling oil pan came from every inch of my skin.

Uesugi Che clenched his fists, took a deep breath subconsciously, and wanted to stand up reflexively.

But the prompt that popped up in front of him made him press his restless body firmly into the medicinal bath again.

[Stimulated by the special medicinal bath, your proficiency in Coronal Breathing is slowly increasing...]

He gritted his teeth and slowly inhaled the hot steam: "Hiss..."

Lilizi, who was standing opposite him, couldn't help but laugh at his rare, embarrassed look. Then, with a frown on her face, she said, "Actually, tempering your body while taking this medicinal bath would be even more effective."

"Like, like this!"

The next moment, a series of dull sounds of bones popping came from the bathtub, echoing continuously in this not-so-small bathing area.

Now, Ririko could no longer maintain her calm expression, but put on the same painful mask as Uesugi Tetsu currently wore.

Strengthening bones, Lilizi is strengthening bones in this medicinal bath!

Seeing this, Uesugi Che also tried to use the罡气 to temper his skin.

But the pain he felt the moment the two touched almost overwhelmed his mind.

Uesugi Che immediately withdrew his internal energy and just stared at the girl opposite him with admiration, who had her fangs embedded in her lips.

Salute to the legendary King of Pain Endurance!

Amidst the terrifying sound of the bone forging, Lilizi spoke intermittently: "Uesugi-kun...when will the water surface become clear...even if the medicinal power is completely absorbed."

"When the time comes... remember to help me."

Uesugi Tetsu nodded silently.

He looked at Lilizi's face, which was twitching with pain, and decided to say something to distract her: "Speaking of which, Lilizi, how did you know the formula for this medicinal bath?"

"When I was little."

The girl trembled as she spoke, her voice almost muffled by the loud cracking of her bones: "While my third sister was making this, she secretly pulled me aside to talk and 'relieve her boredom'."

"My third sister kept muttering about these herbs... I accidentally touched it once, and it hurt so much that I couldn't forget it even if I wanted to."

Lilizi forced a smile, but the momentary smile was quickly drowned out by the overflowing pain and trembling.

This is the practice of the Palace of Flesh.

Every practitioner is the most equal climber in terms of "speed".

If you want to be even a little faster than others, you have to pay a price far greater than that of ordinary people.

She imitated Tokugawa Hoshi's childhood and slowly recited the names of the medicinal herbs one by one.

And Uesugi Tetsu was just like Ririkiko at that time. When he felt the pain for the first time, he memorized the names of dozens or hundreds of medicinal herbs at once with just one use.

——In this way, he could have the Imagawa family prepare medicinal baths for him after entering the Warring States Period.

Two hours later.
