Lin Xue’s face instantly lost all color.
She never expected that Qin Zhan had actually seen through her little trick!
How was that possible? She had done it so discreetly just now—even Zhang Guifang standing right beside her hadn’t noticed!
“Qin… Qin Zhan gege, you misunderstood…”
Lin Xue struggled to get up from the ground, trying to grab Qin Zhan’s sleeve.
“I really didn’t do anything. Maybe I just accidentally touched her…”
“Get lost.”
Qin Zhan sidestepped her, his eyes filled with undisguised disgust.
“Don’t make me say it a third time.”
Lin Xue’s hand froze in mid-air. Tears clung to her eyelashes, ready to fall but not falling, making her look utterly embarrassed.
The surrounding neighbors also fell silent, exchanging uneasy glances.
The situation had flipped way too fast.
Just moments ago, it was “the wild child hitting people,” and in the blink of an eye, it had become “a vicious aunt abusing a child”?
Lin Wan, sitting on the stone stool, watched with great interest, melon seed shells scattered all over the ground.
【Nicely done!】
【As expected of the most protective man in the entire military district. Even if he’s a bit lacking in that department, this level of protectiveness still feels pretty reassuring.】
【But Lin Xue is really stupid. Playing these tricks in front of a special forces soldier? That’s like swinging a broadsword in front of Guan Yu.】
【But speaking of which, shouldn’t the real focus be that thing on the ground?】
【You ignorant fools have no idea—you just missed out on something worth a fortune!】
Qin Zhan frowned slightly at that thought.
That thing on the ground?
He glanced subtly at the pile of scrap metal.
Just a bunch of dismantled gears and coils. What was so special about it?
Lin Wan stuffed the last handful of melon seeds into her mouth, brushed her hands clean, and stood up.
She felt it was time to save this budding genius from being crushed in the cradle.
If that gyroscope really got thrown away as trash, it would be a national loss!
She slowly walked over to Tangtang.
The little girl was looking at her warily, still tightly holding the broken alarm clock case in her arms.
“Who are you? Do you also think I’m a bad child?”
Tangtang’s voice was choked with tears but still stubborn.
Lin Wan didn’t answer. She simply crouched down and lightly touched one of the coils on the ground with her finger.
The system panel in her mind refreshed instantly.
[Detected critical error node.]
[Coil winding turns: 4. Optimal value: 3.5 turns.]
[Missing key component: filtering capacitor. Recommendation: connect a 10µF capacitor in parallel.]
[Wiring diagram error: inverted layout.]
Lin Wan sighed inwardly.
【Child, you’ve got the direction completely wrong—how is this supposed to fly?】
【You wound the enameled wire four turns; the impedance is too high, the current can’t even pass through.】
【You need to remove half a turn—exactly 3.5 turns, not more, not less.】
【And without a capacitor for filtering, the motor will burn out the moment it starts due to current surge.】
【Didn’t you see that little green disc in the junk pile… no, the parts pile? That’s the capacitor!】
【Just connect it in parallel across the motor terminals and it’ll stabilize.】
Tangtang, who had been quietly sobbing, suddenly stopped.
Her wide, tear-filled eyes snapped open as she stared at Lin Wan.
She… she just heard a voice!
That voice was telling her how to fix it!
And what it said directly answered the problems she had been struggling with for days!
Why was it shaking? Why was the motor overheating?
So it was because the coil was over-wound! And because it was missing a capacitor!
Although she was young, Tangtang’s talent in mechanics was monstrous.
The technical terms in Lin Wan’s thoughts would have been incomprehensible to ordinary children.
But Tangtang understood them perfectly—and instantly formed a corrected circuit diagram in her mind.
Her gaze toward Lin Wan changed from caution to shock, then from shock to fervent admiration.
This wasn’t just some random aunt… this was practically a fairy godmother!
Without another word, Tangtang threw the alarm clock to the ground.
Her small, oil-stained hands quickly grabbed the coil.
Under everyone’s stunned gaze, she expertly removed half a turn of enameled wire.
Then she dove into the pile of junk like a little puppy rummaging for something.
“I found it!”
She excitedly held up a tiny green disc about the size of a fingernail.
It was exactly the capacitor Lin Wan had described!
Qin Zhan frowned deeply as he watched the scene.
What was this child doing? Was she going crazy?
And more importantly—why did her movements look like she was following some invisible instruction?
He subconsciously looked toward Lin Wan.
Lin Wan was resting her chin in her hands, smiling as she watched Tangtang, her eyes full of encouragement.
【That’s right!】
【As expected of a genius, she gets it immediately.】
【Be careful when wiring it—don’t reverse the polarity, it’s DC current.】
【The diagram is upside down, sweetheart—flip it 180 degrees and look again.】
Tangtang’s hands paused.
She immediately flipped the drawing over.
Sure enough!
The previously impossible wiring suddenly became completely clear.
At that moment, it felt like her entire world had been illuminated.
Biting her lip, she focused intensely and began assembling.
The neighbors who had been pointing and criticizing were now completely stunned.
“What… what is she doing?”
“Did she get possessed? Why is she messing with that junk again?”
Zhang Guifang sneered, “I think she’s just mentally unstable! Commander Qin, you shouldn’t spoil her anymore—just send her away already.”
Lin Xue also fanned the flames.
“Yes, Qin Zhan gege, look how erratic she is. And the sister earlier said something to her too… both of them seem a bit abnormal…”
“Shut up.”
Qin Zhan said coldly.
His instincts told him something extraordinary was about to happen.
Lin Wan’s inner voice continued.
【It’s done, it’s done! Final step!】
【Connect the battery!】
【The moment of truth is here!】
Tangtang’s small hands trembled slightly.
She picked up two large batteries taken from the radio.
Click.
The batteries snapped into place.
She took a deep breath and flipped the switch.
The entire courtyard fell silent.
All eyes locked onto the ugly contraption—a bizarre mix of alarm clock gears and radio coils.
One second.
Two seconds.
Just as everyone was about to laugh, thinking it was a joke—
“Buzz—”
A low, steady hum sounded.
The propeller (actually a modified fan blade) began spinning rapidly.
Then—
Under everyone’s disbelieving eyes—
The device lifted off the ground.
One centimeter.
Five centimeters.
Ten centimeters!
It hovered in mid-air.
Completely stable, not shaking at all.
As if an invisible hand was holding it up.
“Holy—!”
Someone shouted first.
The entire courtyard exploded into chaos.
