The walk back from the Xiao Clan Smithing Hall was a calculated exercise in extreme biological endurance.
To any servant passing by, the Young Master appeared to be walking with a slow, measured, and flawlessly straight posture. They could not see the micro-spasms rippling through his calves, nor the intense lactic acid burning through his forearms from lifting the heavy forging hammer hundreds of times.
Yoriichi maintained his equilibrium purely through a constant, rhythmic cycle of Total Concentration Breathing, forcefully oxygenating his failing muscles to keep them from seizing.
He reached the private courtyard of his infirmary. He pushed the heavy wooden gate closed and slid the bolt into place with a soft click.
He did not collapse. He did not fall to his knees.
Instead, Yoriichi walked steadily into his room, moved to the edge of his bed, and sat down in a rigid lotus position. He exhaled a long, steady breath of hot, white steam.
'The physical vessel has reached its absolute limit,' Yoriichi analyzed clinically, his mind entirely detached from the screaming agony of his muscles. 'The Resonance Strikes required to purify the iron demanded a caloric and kinetic expenditure that this current body cannot easily sustain. I have entirely drained my muscular reserves. However, the tearing of the muscle fibers will result in a denser, stronger foundation upon recovery.'
He looked down at his hands. They were covered in dark soot from the forge, and his robes smelled faintly of sulfur and burning coal.
A swordsman must maintain his blade, and in this world, his body was his primary weapon.
Fighting through the heavy, leaden fatigue in his limbs, Yoriichi stood up and walked to the bedside basin. He took a damp linen towel and methodically scrubbed the soot and grime from his face, neck, and hands until his pale skin was clean. He removed his dirtied outer robe, donning a fresh, clean inner garment.
With his hygiene restored, he returned to the bed. He arranged his posture perfectly, closed his eyes, and entered a shallow, restorative meditative trance, aggressively commanding his cellular structure to repair itself.
Time lost its meaning in the quiet void of his meditation.
It might have been minutes or an hour later when his heightened senses picked up a familiar set of footsteps approaching the veranda.
It wasn't the sharp, fiery aura of Xiao Yu. It was a warm, steady, albeit deeply weary presence.
Yoriichi's crimson eyes opened calmly.
The sliding door creaked open gently.
"Ning'er? Are you awake?"
An old man stepped inside, carrying a lacquered wooden tray. It was the First Elder, his grandfather.
The old man looked visibly exhausted. The lines on his face seemed deeper today, etched by the severe stress of managing the clan's logistical finances and the mounting, aggressive pressure from the rival Jia Lie Clan in the city's markets. His white beard was slightly disheveled, a clear sign that he had been rushing from meeting to meeting.
But the moment his eyes landed on his grandson, sitting upright and composed on the bed, the heavy burden of clan politics melted away, instantly replaced by a warm, crinkling smile.
"Grandfather," Yoriichi greeted, offering a polite, seated bow. He uncrossed his legs, preparing to stand out of respect.
"No, no, stay seated," the First Elder hurried over, setting the tray gently on the bedside table. "Do not strain yourself. I just came to bring you your midday meal. Yu'er practically threatened the kitchen staff to ensure they made something highly nutritious and digestible for your recovery."
He uncovered the dishes. It was a bowl of premium spiritual rice porridge, mixed with minced medicinal herbs and steamed greens. It was bland, but packed with exactly the dense caloric energy Yoriichi's starving cells were currently screaming for.
"Thank you, Grandfather," Yoriichi said, accepting the bowl. "You should not have troubled yourself to deliver this personally. The administrative affairs of the clan are heavy; a servant could have brought it."
"Nonsense," the old man waved his hand dismissively, pulling up a wooden stool to sit beside the bed. "A grandfather needs to check on his grandson. Besides, escaping those dusty ledgers and arguing elders for a few minutes is a profound blessing."
He watched Yoriichi eat. His sharp eyes scanned the boy's face, noting the lingering paleness and the subtle, heavy fatigue weighing down his grandson's shoulders. His heart clenched slightly.
'He looks so exhausted,' the First Elder thought, a familiar pang of guilt gnawing at him. 'If only I had protected him better in the arena, he wouldn't have to suffer this long, painful recovery.'
He pushed the dark thought away, keeping his smile bright.
"How are you feeling?" the First Elder asked. "Is the boredom of staying in this room driving you mad yet? I know how much you despise being cooped up indoors."
"I am managing optimally," Yoriichi replied smoothly, taking a measured spoonful of the medicinal porridge. "The quiet is... instructive. It provides me with the necessary time to think and solidify my foundation."
"Thinking is good," the First Elder nodded, chuckling softly. "But do not overthink, Ning'er. It causes premature wrinkles, and you are far too young to look like this old man."
