The second academic year entered its third week.
At exactly six in the morning, the dormitory corridor lights shifted from dim to bright.
The transition was compressed into three seconds. No flicker.
One hundred fifty remained one hundred fifty.
When the roll call system activated, a blue cursor slid from the first line to the last.
It stopped at the total count.
No additions.
No replacements.
No deletions.
The academy was like a machine that had completed calibration, now entering constant-speed operation.
Footsteps echoed through the hallway.
Different soles, the same rhythm.
The schedule had not changed.
The timetable had not changed.
The electronic panel outside the classroom displayed:
Second Academic Year · Week Three.
Even the weather forecast felt overly regulated.
Clear skies.
Wind level one.
Humidity constant.
Stable.
The air temperature remained within a range suited for prolonged training.
Breathing was smooth, without heaviness.
This was the state the academy was most satisfied with.
Leaves outside the window swayed slightly—at identical angles.
Corridor echoes remained even.
Stability was a form of satisfaction that could be quantified.
Tuesday Afternoon | Ability Training
The electronic prompt sounded on time.
The audio frequency was precise.
Exactly one second in duration.
More accurate than a student's heartbeat.
The training hall lights turned on.
Cold white illumination spread downward.
Walls, floor, and ceiling entered clarity at the same instant.
The air carried a mix of metal and disinfectant.
Slightly dry.
Second Year, Class One. Number Seven.
Seven stood in his usual position.
Toes aligned with the marking line.
Shoulders relaxed, but not slack.
No one deliberately gave him space.
Yet the gap around him was always just right.
Half a step in every direction.
Neither isolated nor crowded.
"Today's session is combined combat."
The instructor's tone was steady.
"Second-tier and first-tier ability users will be mixed."
A slight disturbance ran through the group.
Shoes shifted subtly.
Someone adjusted a wrist guard.
Mixed grouping meant uncertainty.
Variables.
Seven heard several thoughts pass by.
"Second-tier will suppress, right…"
"What if someone loses control?"
"Number Seven should be fine."
The name "Seven" was treated as a default safety term in their thoughts.
Like a safeguard.
He did not react.
Groups were assigned.
He was placed in Group Three.
Opposite him stood a first-tier wind-type user.
The opponent's Adam's apple moved.
Fingers opened, then clenched.
Mental fluctuation: elevated.
The start signal dropped.
Wind blades formed.
First—angle too low.
Second—too fast, insufficient control.
Third—mental guidance lagging by half a beat.
Disordered rhythm.
Air currents scraped the ground, lifting fine dust.
Seven did not evade immediately.
He first assessed the opponent's fear.
Shoulder muscles tightened.
Breathing quickened.
"Can't lose."
"Can't get eliminated."
The thoughts pressed too heavily.
Seven shifted sideways.
Half a step.
His heel touched the ground with barely a sound.
He guided the airflow.
Not suppression.
Just redirection.
The wind deviated.
The current brushed past his shoulder.
Fabric lifted.
First second.
The opponent thought it hit.
Second second.
Overconcentration caused deviation.
Third second.
Stamina began to drop.
Seven maintained his pace.
No counterattack.
No suppression.
When the match ended, the opponent's breathing was disordered.
Chest rising excessively.
Seven's breathing remained stable.
System record:
[No. 7: Combat Adaptability Increased]
Behind the observation window, low voices:
"He's matching the opponent's rhythm."
"A stable individual can serve as a metronome."
Metronome.
Seven remembered the word.
A metronome does not rush.
Nor does it lag.
It only maintains.
Thursday Afternoon | Ability Training
The lights dimmed by two levels.
Not enough darkness to form shadows, but enough to flatten spatial depth.
This week introduced mental endurance testing.
Transparent compartments rose.
A faint vibration traveled through the ground.
Low-frequency noise activated.
First layer—continuous vibration.
Second layer—frequency stacking.
Third layer—intermittent insertion.
The sound was not sharp.
It pressed deep into the bones of the ear.
The air seemed thicker.
"Objective: maintain stable output."
Seven stood at the center.
Feet shoulder-width apart.
Breathing entered a fixed rhythm.
The low frequency pressed over his lungs like a tide.
First wave—heart rate showed signs of rising.
He adjusted it downward.
Inhale, four beats.
Pause.
Exhale, four beats.
Second wave stacked.
The mental curve showed slight fluctuation.
Behind the observation window, thoughts intensified:
"Is there fluctuation?"
"His mental curve is too stable."
"Abnormal suppression?"
Abnormal suppression.
A faint pulse throbbed at Seven's temples.
He could not be too stable.
But he also could not be unstable.
The third layer cut in.
A sudden disruption.
He introduced a minor fluctuation.
Amplitude controlled within the boundary.
Like a ripple across still water.
System judgment:
[Mental Stability Range: Qualified]
Green light illuminated.
The compartment door opened.
Airflow returned.
When Seven stepped out, his palms were slightly damp.
The cost of maintaining—was constant correction.
Saturday Morning | Ability Training
Combined combat continued.
This week, scoring weight increased.
Results would affect class ranking.
The air carried an added layer of tension.
"Must enter top ten."
"Stability isn't enough."
Seven stood at the starting point.
Sunlight filtered through the high windows onto the floor.
His opponent was calmer than last week.
Jaw tightened.
Breathing steady.
The signal sounded.
Attack speed increased.
First strike—direct advance.
Second—precise angle.
Denser airflow.
Seven stepped back.
One step.
First second.
The opponent closed in.
Second second.
A wind blade grazed his sleeve.
A thin tear formed.
Third second.
Mental fluctuation rose.
He could have ended it.
But that would create an abnormal curve.
He extended it by three seconds.
Fourth second.
Opponent misjudged.
Fifth second.
Stamina dropped.
Sixth second.
Footing slipped.
Fall.
End.
Record generated:
[No. 7: Stable Output for Three Consecutive Weeks]
Behind the observation window:
"Template confirmed."
"Can be used as a basis for cycle compression."
Cycle compression.
Six years was too long.
Stable individuals as the foundation.
Seven turned and left.
A classmate asked quietly:
"Seven… do you really never get nervous?"
He paused.
Shoulder line unmoved.
No answer.
Nervousness would not change the system.
The bell rang.
Class ended.
The screen flickered.
Data uploaded.
In the corridor, the footsteps of 150 people echoed.
Uniform.
Shadows overlapped across the floor.
Seven walked in the middle.
Wind slipped in through the window gap.
His hair moved slightly.
Stable.
Metronome.
Template.
Cycle compression.
The words aligned in his mind.
He did not resist.
He did not comply.
He only maintained.
The second academic year continued operating.
Data kept recording.
Stability was being used.
And he—
continued to maintain.
Until the day he no longer could.
