Jing Mingqiu originally thought that after the system upgrade, the modification of the original C-class household appliances would become B-class or A-class, allowing him to repair more high-end appliances like mobile phones and computers.
However, when the system truly upgraded, Jing Mingqiu discovered that the repair level of appliances had not increased; instead, the modification of C-class small vehicles had been added.
On the way to the restaurant, Jing Mingqiu had already scanned various vehicles on the road to get a basic understanding of their grades.
All vehicles powered by fuel, whether motorcycles or cars, were C-class or above. Only electric vehicles and bicycles were classified as C-class vehicles.
Jing Mingqiu was not interested in bicycles that required pedaling, so only electric vehicles remained as an option.
He pushed his mother's electric scooter, used for grocery shopping, into the hall and, without hesitation, threw a scan at it.
【Scanning…】
【Name: Small Shuangfeng Electric Scooter】
【Frame Main Beam: Minor wear, partially twisted, can be modified and upgraded】
【Engine: Insufficient bearing strength, insufficient power, can increase cylinder count】
【Control System: Insufficient chip precision, can replace chip】httpδ:/m.kuAisugg.nět
【Brake System: Severely worn brake pads, replacement recommended】
【……】
【Scan Result: This electric scooter is of low quality. Modification plan has been generated. Select?】
As the system level increased, the number of modification plans also grew. More helpfully, a filtering function was added, allowing Jing Mingqiu to choose more suitable plans based on his requirements.
"Speed, range, load capacity…"
After carefully selecting, and considering the equipment available, Jing Mingqiu chose a modification plan primarily focused on increasing speed, with range enhancement as a secondary goal.
To modify, one must first disassemble. Jing Mingqiu worked with nimble hands. In less than five minutes, he had removed the engine from the electric scooter's rear wheel.
Conventional engine modification involves increasing speed by expanding displacement and adjusting gear ratios, while maintaining horsepower.
However, this method is only suitable for internal combustion engines and has little effect on the electric motors used in electric vehicles.
Internal combustion engines essentially rely on combustion reactions to drive pistons, requiring at least two reaction cylinders to maintain stable power output.
Electric motors are different. Provided the battery supply is stable, increasing the magnetic force of the conducting wires can directly enhance the motor's power.
Using specialized tools, after prying open the engine casing, Jing Mingqiu, guided by the system, raised his small hammer and began tapping on the rotor's magnetic steel.
In Dragon Country, the precision of ordinary lathes is only 0.1mm. The minimum requirement for an Eighth Grade Technician is a "five-silk touch" and "three-silk eyesight."
One silk equals 0.01mm.
In other words, after acquiring the skills of an Eighth Grade fitter, Jing Mingqiu's purely hand-crafted precision had reached three times that of ordinary machine tool processing.
Initially, Jing Mingqiu was somewhat unfamiliar with engine modification, and his speed was a little slow. Soon, however, he became accustomed to the engine's structure, and his modification speed rapidly increased.
Engine, controller, frame, battery…
From the inside out, from bottom to top, after more than two hours of work, Jing Mingqiu completed the first modified vehicle of his life.
Even though it was just a small electric scooter, it did not diminish his excitement.
A system message popped up.
【Congratulations to the host for completing the Small Shuangfeng Electric Scooter. You have gained thirty-five technology points.】
【Current upgrade progress: 35/200】
"Looks like I won't be able to reach Level 3 system anytime soon," Jing Mingqiu muttered to himself, then closed the system message and pushed the electric scooter out of the repair shop.
"I wonder how good the system-modified electric scooter will be? I should take it for a spin. My groceries are running low anyway, so I might as well go to the market and buy some."
Saying this, Jing Mingqiu eagerly hopped onto the scooter. He gripped the throttle, turning it counter-clockwise by fifteen degrees. The engine hummed, the tires began to spin, and the electric scooter smoothly started moving.
Jing Mingqiu carefully observed, ensuring the vehicle had no vibrations or abnormal noises, then gradually loosened his grip. He turned the throttle another fifty degrees.
The throttle is the speed control component of an electric scooter. The greater the rotation angle of the throttle, the more current the engine receives, the greater the power generated by the electric motor, and the faster the electric scooter goes.
Thirty kilometers per hour, sixty, ninety, one hundred and twenty…
As the throttle rotated further, the electric scooter's speed increased dramatically. The wind hit Jing Mingqiu's face like a knife. He quickly lowered his helmet's visor, barely able to open his eyes.
"Awesome!"
Watching the surroundings blur past, Jing Mingqiu's heart surged, and he couldn't help but shout.
After shouting a couple of times, Jing Mingqiu felt something was missing. He looked down and saw only the remaining battery power displayed on the dashboard, and a realization dawned.
"What a shame, electric scooters don't have speedometers. I don't know how fast this thing really is?"
Just as Jing Mingqiu was considering whether to go back to the shop to install a speedometer before continuing his grocery shopping, he unintentionally spotted a motorcycle ahead, and a bold idea surfaced in his mind.
"The electric scooter doesn't have a speedometer, so I can't see the speed, but motorcycles do. If one rides alongside me, I can test the maximum speed of my modified vehicle!"
With this thought, Jing Mingqiu decisively increased the throttle angle. As the power increased, the electric scooter's speed soared, quickly catching up to the motorcycle ahead.
"Hey, buddy, could you please help me…"
Before Jing Mingqiu could finish speaking, the motorcycle suddenly accelerated, leaving him far behind.
It was three in the afternoon, and the road was very quiet, with only this one motorcycle. Jing Mingqiu had no choice but to follow and accelerate.
Two minutes later, Jing Mingqiu caught up to the motorcycle again: "Buddy, you…"
As soon as Jing Mingqiu started speaking, the motorcycle accelerated again, leaving him behind…
Thus, the two chased each other, quickly traversing more than half the city.
The chase finally ended when a roadblock appeared ahead.
"You two sure can run," a middle-aged traffic police officer approached, his face stern. "Driver's license and registration, please."
The motorcycle rider took off his helmet, his face filled with bitterness. He took out his documents from his bag and respectfully handed them over.
The police officer took the documents, flipped through them, and frowned. "Wang Ankang, your parents named you this hoping you would be safe and healthy. Why are you speeding on the road!"
Wang Ankang lowered his head, not daring to meet the officer's gaze.
"And you?" The officer walked up to Jing Mingqiu, looking at his youthful face, his frown deepening. "So young, and already up to no good, racing with others. What if something happens?"
Jing Mingqiu was stunned and quickly began to explain…
