When the prototype vehicle rumbled into the wide clearing behind Wangshu Inn, the entire construction team stopped working. Even the Qianyan Army officers, normally stoic and disciplined, froze and stared.
A strange metal object with wheels—four of them—glinted under the sunlight. Panels were still exposed, pipes visible, and the frame was raw and unpainted, but it was unmistakably something new.
Something Teyvat had never seen.
Something impossible.
And everyone knew who made it possible.
Takumi.
THE FINAL CHECK
Takumi sat in the driver's seat and adjusted the chair height.
Behind him, Sucrose peeked over Albedo's shoulder nervously, while Klee sat on the floor hugging her backpack, vibrating with excitement.
Cloud Retainer observed the vehicle with a dignified air, chin tilted ever so slightly. "Not bad," she declared. "A functional transport machine… such creations would have impressed even the ancient Liyue artisans."
Her tone rose in pride. "Naturally, since I am involved, excellence is expected."
Keqing crossed her arms. "Cloud Retainer, please don't rewrite history just because you're proud."
"Hmph! This immortal rewrites nothing. I simply emphasize the truth!"
Albedo cleared his throat gently. "…The inner elemental furnace is operational. I've stabilized the conduction plates. Takumi, whenever you're ready, we may proceed."
Takumi nodded and placed his hand on the ignition dial.
SYSTEM INTERFACE — INTERNAL
A blue hologram flickered in front of Takumi alone.
[SYSTEM] — NEW DEVICE DETECTED
Prototype Model: Teyvat Vehicle (Type-01)
Status: Operational
Energy Input: 12% (Vision slot empty)
Stability Rating: 82%
Suggested: Field Test]
Takumi exhaled.
Time to make history.
THE FIRST START-UP
"Alright," Takumi said, "let's begin."
He inserted a small Electro elemental crystal into a circular socket.
Immediately—
Vrrrrrm… vrrrrrrrrrMM—!
The engine awakened.
Cloud Retainer's eyes widened.
Keqing jumped.
Sucrose squeaked and clutched Albedo's cloak.
Klee bounced like an excited slime. "IT'S ALIVE!!"
Takumi tapped the panel. "Compression's stable… no shaking… noise level acceptable."
Albedo stepped forward, fascinated. "Amazing. The elemental conduction is smoother than expected."
Cloud Retainer let out a soft "hmph." "Of course! My mechanical system ensures such perfection."
Takumi smiled. "Cloud Retainer, your mechanical joints are flawless. This would be impossible without you."
Hearing that, Cloud Retainer puffed her chest with pride. "Hmph! Correct."
She absolutely enjoyed the praise.
THE CROWD GATHERS
More people gathered quickly—the Liyue alchemists, the Qianyan Army, the construction workers, even Verr Goldet peeking from the Inn balcony.
But then—
A blue silhouette raced across Guili Plains.
GANYU.
Breathless and slightly flustered, she rushed up with her bow strapped tightly across her back.
"Takumi! Keqing! I heard Cloud Retainer was here and—oh?"
Her voice trailed off as she saw the car.
Keqing waved. "Perfect timing, Ganyu. You can witness Liyue's first vehicle."
Ganyu blinked. Twice. Then again.
"…It has wheels."
Cloud Retainer nodded proudly. "Indeed. Behold, a machine that moves without beasts or wind. A marvel we have created together."
Ganyu murmured, overwhelmed, "Liyue's productivity reports are going to explode…"
Klee tugged on her sleeve. "Sister Ganyu! Do you want a ride later?"
Ganyu paled. "A-A ride? At… high speeds…?"
Sucrose whispered to Albedo, "I think she might faint if she rides it."
Albedo nodded gravely. "We must prepare emergency sweet flower tea."
TAKUMI'S EXPLANATION — BLUEPRINT TECHNOLOGY
While everyone murmured excitedly, Takumi opened a projection of the car's internal blueprint. Only he could see the full diagnostic codes, but the team could see the simplified layout.
Takumi pointed at the projected structure.
"This is the Blueprint Module's breakdown for internal systems."
🔧 Simplified Explanation (Public Version)
Main Furnace: Converts elemental energy into mechanical rotation
Drive Shaft: Transfers force to the wheels
Steering Rack: Controls direction
Brake Lattice: Uses Geo-based friction plates
Indicator Panel: Detects issues and warns the driver
Energy Gauge: Shows remaining elemental energy / Vision power
Keqing leaned closer. "Amazing… you even integrated elemental compatibility. So, Vision users can drive endlessly?"
Takumi nodded. "Correct. Vision holders can power the furnace directly. No crystals needed."
Cloud Retainer tapped her beak against a wire. "This wiring… this blueprint technology… how were you able to design such a thing?"
Takumi smiled but didn't answer directly.
Only the system spoke inside his mind.
[SYSTEM] — BLUEPRINT MODULE
Function: Converts knowledge + imagination into buildable schematics.
Unique to User.
He couldn't reveal that.
Instead, he said:
"A combination of memory from my homeland and techniques learned in Liyue."
Cloud Retainer accepted this with a nod. "Satisfactory."
TEST RUN BEGINNING
"Alright!" Takumi cracked his knuckles.
"Everyone stand clear! First field test. I'll drive."
Klee jumped. "Klee too! Klee too!"
"No," Keqing said instantly.
"Klee stays OUTSIDE the vehicle during the first test."
Cloud Retainer agreed. "Lest the car be mysteriously blown to pieces."
Klee pouted. "Klee won't explode the car… probably."
Ganyu raised her hand shyly. "Um… I'll stand very far away."
Sucrose nodded rapidly. "I'll stand behind Ganyu."
Albedo grabbed his notebook. "Beginning observation."
Cloud Retainer stood tall, ready to judge like a teacher evaluating a project from overly confident students.
Takumi took a deep breath.
"Starting.
Three… two… one."
He gently pressed the acceleration pedal.
THE WORLD'S FIRST DRIVE
The car rolled forward—
Smooth.
Steady.
Controlled.
No shaking.
No bursting.
No magical overload.
Just a clean mechanical glide over the stone surface.
The crowd collectively gasped.
Takumi smiled and accelerated slightly.
VrrrMMMMM—!
The car picked up speed smoothly, leaving a small trail of dust behind it.
Workers cheered.
Alchemists scribbled notes furiously.
Ganyu clapped softly.
Keqing looked like she might faint from excitement.
Cloud Retainer's eyes gleamed.
Klee ran after the car, laughing. "Brother Takumi is so fast!!"
He slowed, turned around, and drove back in a perfect semicircle.
Cloud Retainer evaluated: "Maneuverability: acceptable."
Albedo: "Elemental conduction: stable."
Keqing: "Amazing! This will change everything!"
Ganyu: "Transportation reports… I will need so many forms…"
Klee: "CAN WE MAKE A TANK VERSION!?"
Everyone: "NO!"
AN IMPOSSIBLE REALITY
Takumi parked the car gently.
Silence.
Then—the Qianyan soldiers erupted into applause.
Construction workers shouted praise.
Alchemists let out gasps of awe.
Even Verr Goldet clapped from the balcony.
Cloud Retainer lifted her chin proudly.
"Very well. This immortal acknowledges the success."
Keqing stepped forward, eyes bright.
"Takumi… with this, Liyue can become an industrial nation."
Ganyu added softly, "It will make life easier for our people… and help us expand our economy."
Albedo nodded. "And perhaps… this will inspire future inventions."
Klee jumped and hugged Takumi's leg. "Brother Takumi made the coolest toy ever!!"
Takumi smiled warmly.
"No, Klee.
Not a toy.
The future of Liyue."
And somewhere deep inside the system—
[SYSTEM] — MILESTONE ACHIEVED
Teyvat's First Vehicle Created
Unlocking New Modules Soon…
Takumi felt the blueprint engine humming like a heartbeat.
This was only the beginning.
