After hearing Xia Feng's explanation, Tanjiro looked surprised.
"K-Keeping Total Concentration all day… is that really possible?!"
Just imagining it sounded extremely painful!
From the next bed, Zenitsu instantly exploded.
"Impossible! Your lungs would explode!"
Xia Feng shook his head lazily.
"That's basic stuff. If you want to become a Hashira, you have to reach that level."
Tanjiro blinked and subconsciously asked,
"Can you do it too, Mr. Xia Feng?"
Xia Feng froze for a few seconds.
Then he glared at Tanjiro.
"I don't need to! My physical condition is already excellent!"
He wasn't lying.
Total Concentration Breathing mainly stimulated lung function and strengthened the body.
But Xia Feng's body had already been enhanced by the system.
His physical strength wasn't an issue at all.
So he didn't strictly need Total Concentration Constant—training it would only be icing on the cake.
Seeing Tanjiro about to ask more questions, Xia Feng slapped him lightly on the head.
"Stop asking useless questions. Just train when I tell you to!"
"Starting today. Remember—don't stop even when you're sleeping!"
After saying that, he looked at his own hand.
Tanjiro's skull was ridiculously hard.
That slap had actually made his hand hurt.
Tanjiro almost cried.
"But I can't control it while I'm asleep…"
Even if he wanted to resist Xia Feng's tyrannical training plan—
It was obviously useless.
After dealing with Tanjiro, Xia Feng walked over to Zenitsu's bed.
He glanced at Zenitsu's slightly deformed limbs.
Just like in the original story, Zenitsu had encountered the poison-spitting spider demon and fought fiercely.
But unlike the original plot—
Zenitsu had actually fought bravely this time before accidentally being poisoned by a spider.
He hadn't been pathetic the entire time until falling asleep and suddenly unleashing a big move.
"Can… can I still be saved?"
Zenitsu asked with hopeful eyes.
Xia Feng sighed.
"We'll have to see how the treatment goes."
"If it works well… you probably won't die within three to five years."
Zenitsu's face turned green instantly.
He stared at Xia Feng in horror.
"Wait! Hold on!"
"Were you serious just now?!"
Xia Feng nodded.
"Yes."
Then he added,
"I was seriously talking nonsense."
Before he could finish—
Zenitsu had already fainted.
Xia Feng: "..."
Zenitsu really had it lucky.
Good thing he had the ability to become stronger when asleep and plot armor protecting him.
If it were a normal person with that level of courage—
They would have died on the battlefield eight hundred times already.
After leaving the treatment room, Xia Feng noticed Aoi Kanzaki sitting quietly outside the door.
"What's wrong? You look bored out of your mind."
He asked curiously.
Seeing it was Xia Feng, Aoi snapped out of her thoughts.
"N-Nothing… I was just thinking about something."
Xia Feng noticed the complicated look on her face and sat down across from her.
He didn't say anything.
He just smiled and waited.
Aoi looked toward the ward.
Tanjiro and the others were lying inside that room.
She sighed softly.
"Seeing them reminds me of my past self."
"If I hadn't backed out back then… and had fought in life-and-death battles like them…"
"Could I have become as strong as them?"
Xia Feng thought for a moment.
"Probably not. Your talent is much worse than theirs."
Aoi: "..."
She looked at Xia Feng with a conflicted expression.
Even though she knew he was telling the truth—
Hearing him say it so bluntly still made her feel a little annoyed.
Seeing her reaction, Xia Feng grinned.
This serious little girl was really fun to tease.
Aoi said helplessly,
"Please stop teasing me! I'm actually feeling quite depressed!"
"We're around the same age, yet our strength is worlds apart. It's frustrating."
Xia Feng paused for a moment.
"Isn't that normal? I'm the same age as you too. Why don't you compare yourself with me?"
Aoi froze.
She stared at Xia Feng for a long time, then said in shock,
"I… never realized that."
She looked troubled.
"Even though Mr. Xia Feng is about the same age as us, I always subconsciously feel like you're much older…"
Much older?
Xia Feng's eyelid twitched.
If it were someone else saying that, he might have punched them already.
He rolled his eyes.
"So basically… you want to become stronger, right?"
Aoi nodded instinctively.
Xia Feng smiled.
"That's easy."
"Become my disciple. I'll teach you."
Aoi froze.
"You… you mean…"
"You want me to become your Tsuguko?"
Xia Feng tilted his head.
"Tsuguko… yeah, something like that. The term sounds a little weird, but I don't mind."
Aoi pressed her lips together, her heartbeat quickening.
Xia Feng's abilities were widely acknowledged within the Demon Slayer Corps.
Whether it was strength, achievements, or potential, he ranked at the very top.
Becoming Xia Feng's Tsuguko—
Just that title alone would allow someone to walk around the Corps with pride.
For her… for any Demon Slayer—
It was an extremely tempting opportunity.
She took a deep breath to calm herself.
After several seconds, she clenched her teeth and shook her head firmly.
"I'm sorry!"
"I can't accept your offer!"
"Even though this is an incredible opportunity for me…"
"I know my own abilities. Such an important position shouldn't be wasted on someone like me!"
She bowed deeply to Xia Feng.
"So please give this opportunity to someone with a brighter future!"
After saying that, she seemed much more relaxed and even smiled.
"And besides… I suddenly realized something."
"I actually like my current work."
"Being able to contribute at Butterfly Estate is already the best way for me to realize my life's value!"
With that, Aoi gave him a bright smile and returned to work.
Watching her back as she left, Xia Feng fell into deep thought.
Why does this atmosphere feel like…
I just got rejected after confessing?
