"Sun Breathing—Second Form: Clear Blue Sky."
Lin Chen gripped the blade with both hands, swinging forcefully, unleashing a slash that erupted like flames.
Breathing techniques paired with a Nichirin blade—this was the true, complete form of a breathing technique swordsman.
Along with his breathing, it was as if special energy within the Nichirin blade was being drawn out, amplifying the sword technique's power.
Unfortunately, this wasn't Lin Chen's own Nichirin blade.
Nichirin blades would bind to their users, changing color based on the first swordsman who gripped them.
The color change had various different properties.
Like the Nichirin blade he was using now—it was Urokodaki Sakonji's.
The blade was blue, and even somewhat conflicted with Sun Breathing's attributes.
"So this is Sun Breathing?"
Lin Chen's sparring partner was Urokodaki Sakonji.
He dodged Lin Chen's full-powered strike, yet could feel the wave of heat rushing toward him.
It truly was a strike of astonishing power.
To the side, Fujiwara Chika boredly cupped her face, watching Lin Chen and Urokodaki Sakonji's sparring session together with Nezuko.
She liked hardworking boys, but she didn't like combat.
She didn't like fighting, didn't like martial training.
Unless it was something like the Dance of the Fire God.
Thinking back to that dance practice in the snow, Secretary Fujiwara's face flushed slightly red.
Unfortunately, after waking up, Lin Chen had immediately started training and completely ignored her.
Which annoyed her quite a bit.
At this moment, it was already the third day since Lin Chen and Chika had crossed into the Demon Slayer world.
The first night, they had encountered Tanjuro.
The second day was spent traveling all day.
Today, everyone had moved to temporarily stay at Urokodaki Sakonji's home near Mount Sagiri.
The high-martial world's radiation influence on this world wasn't particularly strong.
The two sides only seemed to have a cooperative relationship within a certain range.
The high-martial world's technology hadn't spread to this world.
Communication within the Demon Slayer Corps still relied on the miraculous Kasugai Crows.
The Kasugai Crow had already been sent out last night, and getting a reply from Demon Slayer Corps headquarters would take at least another half day.
Urokodaki Sakonji was also a very experienced swordsman trainer.
Although he couldn't help much with breathing techniques, his help with swordsmanship and combat experience was substantial.
[Sun Breathing Swordsmanship proficiency +3]
In just two hours of morning sparring, Lin Chen's swordsmanship proficiency had directly increased by three.
His Sun Breathing swordsmanship proficiency itself wasn't that high originally.
The resonance with Yoriichi that time, plus this time, had directly pushed his swordsmanship to LV3.
Now, his panel had undergone astonishing changes compared to before arriving in the Demon Slayer world.
[Host: Lin Chen]
[Class: Sun Breathing Swordsman (Destined Demon Slayer)]
[Breathing Technique: Sun Breathing LV3 (3/50)]
[Sun Breathing Swordsmanship: LV3 (1/50)]
[Combat Level: Stone-Crushing]
[Combat Evaluation: Basically equal to Tanjiro when he severed the giant boulder.]
His breathing technique had broken through yesterday while traveling.
The biggest advantage of breathing technique training over swordsmanship training was that it could be practiced anytime, anywhere.
In two days in the Demon Slayer world, his improvement basically equaled Tanjiro's two years.
However, Lin Chen was well aware this was eating up dividends.
It wasn't from his diligent training—it was small opportunities that had brought great improvements.
The next big improvement would require fifty proficiency points.
Based on current proficiency gains, it would probably take nearly ten days of hard training.
But as for his current strength, Lin Chen was already quite satisfied.
After all, he'd only crossed over a few days ago, and had already gone from a class nobody to probably being among the school's top students.
"Once I get back, I can finally show my divinity to the world."
Lin Chen felt secretly pleased.
"I just don't know what level my body rank is at now."
When his breathing technique broke through yesterday, his body level should have also had a breakthrough.
This was also the perverted aspect of the Martial Arts Panel—when techniques linked to physical fitness broke through, they brought direct physical feedback.
The breakthrough from breathing technique Stage 2 to Stage 3 was quite significant.
It's just that he currently didn't have equipment to test his body level in real-time.
However, by his estimation, it should have increased by at least one level.
Body LV3 or above, LV3 Sun Breathing, LV3 Sun Breathing swordsmanship.
At school, this would count as being a top student.
His body level was slightly lacking, but among students, his realm was absolutely quite high.
You had to know—even Xia Mi, that openly top-three student at school, one of the absolute elite.
Her publicly known breathing technique was also only at Stage 3.
As for hiding things, laying low—
That wasn't something he needed to consider right now.
Aside from transmigration and the cheat, other things weren't matters requiring serious consideration.
His current rate of improvement, compared to those true monsters and geniuses, didn't amount to much at all.
Moreover, he wasn't without backing now either.
Lin Chen glanced to the side at Secretary Fujiwara, who was covering her face looking utterly bored.
With this experience, given Secretary Fujiwara's personality, even if she didn't fall in love with him, they'd at least be friends.
With that connection, in Z City, many small problems wouldn't be problems.
The Fujiwara family was quite a significant local power in Z City.
"So, should I give Secretary a bit more warmth?"
Lin Chen looked at Secretary Fujiwara and thought.
This wasn't some young lady from a slice-of-life anime worldview, but a genuine local power holder in the high-martial worldview.
Building a good relationship would definitely be of considerable help to him.
These days, even with martial training and cheats, you had to know how to be flexible.
Only knowing martial training worked, but it was slow and dangerous.
Only being a kept man also worked, but you had no freedom.
Martial training + cheat + being kept—he should be able to practice martial arts while standing tall, right?
Thinking this.
Lin Chen wiped the sweat from his body, returned the Nichirin blade to Urokodaki Sakonji, then walked over to Secretary Fujiwara.
"Let's practice the Dance of the Fire God together this afternoon, Fujiwara-sensei. I can teach you."
Lin Chen spoke with a smile.
Handsome features plus a masculine warrior's temperament were indeed quite attractive.
Combined with his firm attitude in the snow before and his full sense of security.
At this moment, Fujiwara Chika inexplicably felt her cheeks heating up.
She liked firm, hardworking boys.
Lin Chen fit her ideal of romance quite well in all aspects.
'What should I do, Kaguya-san?'
At this moment, Secretary Fujiwara really wanted to find her best friend for a good heart-to-heart.
Unfortunately, this was another world.
"Thank you, Sensei."
Secretary Fujiwara's cheeks flushed slightly red as she lowered her head slightly.
"Eh?, so Fujiwara-sensei can actually blush?"
Lin Chen was rather surprised.
His perception of Fujiwara Chika was as Earth's Cancer, a demon-lord-level destroyer, the Student Council President's "mama-san."
In the original work, a romance anime where Fujiwara Chika had such high popularity and was such a beautiful girl, yet remained without an official CP until the very end.
That alone said a lot.
He just hadn't expected that Secretary seemed to have quite a favorable impression of him.
Lin Chen wasn't some oblivious, blind male protagonist—he'd watched plenty of romance anime and harem novels.
How could he fail to judge Secretary's current state?
Mm, this kept man life just got even more appealing.
