Long Country, Dongyang City.
Mid-June, the sun shone brightly, and summer cicadas chirped incessantly on the trees.
Beneath the tall street trees, seven or eight shops were lined up, with one of them having a particularly simple signboard.
It was just a broken wooden board, with "Da Shan Home Appliance Repair Shop" written on it in paint.
At this moment, a taxi was parked in front of the shop. A man in jeans was carrying a suitcase into the car, and a middle-aged woman in a sun-proof jacket stood beside him. A teenager from the repair shop was gently admonishing them.
"Xiao Qiu, your dad and I are going out for a few days, and the repair shop is left to you. Don't overexert yourself. Repair what you can, and leave what you can't until your dad gets back..."
"That's right, don't try to be a hero," the man added after putting away the luggage, "it'll be trouble if you break someone else's things."
The teenager nodded first, then said with a hint of unwillingness, "Dad, are you really not taking me on your trip?"
"You're an adult now, you need to learn to be independent!"
After saying this, the man pulled the middle-aged woman into the taxi and quickly drove away.
Watching the taxi recede into the distance, the teenager sighed, turned, and sat down on the sofa next to him, looking utterly dejected.
His name was Jing Mingqiu, and he had just finished his college entrance examination and graduated from high school.
The middle-aged man outside was his father, Jing Dashan, and the one beside him was his mother, Zhao Cui.
According to them, they had worked hard for most of their lives and hadn't gone out to see the world. Now that Jing Mingqiu had grown up, they could finally relax and go on a vacation.
"This is really like a giant panda before the college entrance exam and a stray cat after," Jing Mingqiu was complaining fiercely when a mechanical voice sounded in his mind, followed by the appearance of a semi-transparent panel.
[Congratulations Host, you have obtained the Black Technology System.]
[Current System Level: Level One]
[Current Research Points: 0]
[The Host can increase the system level by accumulating research points.]
[As the system level increases, more functions will be unlocked.]
[Current Function: C-class Household Appliance Modification Scan.]
[Newbie Gift Pack has been issued, please check it.]
"It's a system, this is great!"
As a veteran reader of countless online novels, Jing Mingqiu was no stranger to systems. After the initial joy, he quickly calmed down and began to study it seriously.
"Black Technology System, judging by the name, it should be about creating various high-end technological products."
"It's currently a Level One system, and upgrading requires research points. But where can I get research points?"
"Based on the system's functions, it should be by upgrading and modifying electronic products to gain research points..."
With the enlightenment from numerous online novels, Jing Mingqiu quickly figured out how to use the system, and also claimed the newbie gift pack from the system, which gave him a skill book called "Level 8 Fitter."
To grind what cannot be ground, to saw what cannot be sawn; holding a file, one can file an aircraft carrier, a world; such is a Level 8 Fitter. In today's China, such individuals are rare.
At first, Jing Mingqiu thought the description of the Level 8 Fitter below the skill book was an exaggeration. It was only after he truly acquired this ability that he understood the power of a Level 8 Fitter.
Using his eyes as a ruler and his hands as a scale, whether it was a wrench or a screwdriver, they all felt like extensions of his own body.
Jing Mingqiu took out the knock-off phone he had been using for three years, preparing to make it his first modification target.
[Scanning...]
[Target product is a Class A household appliance, exceeding modification range.]
[Please Host upgrade system level as soon as possible.]
Discovering that the phone exceeded the modification level, Jing Mingqiu did not give up. Instead, he turned and scanned all the appliances in the shop.
"The phone won't work, the computer won't work either. For my first modification, can I only fix a broken radio?"
As Jing Mingqiu hesitated whether to modify the TV or the radio for his first attempt, a chubby kid came running in, carrying a drone.
"Uncle Jing, Uncle Jing, please take a look quickly! My drone is broken again! I was flying it, and it suddenly lost control and crashed into a tree with a bang! I picked it up and found that the propeller wasn't turning."
"Little Fatty, my dad is out traveling. Why is your drone broken again?"
Little Fatty's full name was Sun Heng, a childhood friend of Jing Mingqiu and a regular customer at the shop. He used an old drone that broke down every few days.
As he greeted him, Jing Mingqiu habitually scanned the drone.
[Scanning...]
[Name: Small min2 unmanned aerial vehicle.]
[Aircraft frame: Slightly cracked, partially distorted, can be modified and upgraded.]
[Propulsion motor: Coil slightly worn, can be replaced with better material.]
[Control system: Three chips burnt out, electronic pathways obstructed, chips can be replaced.]
[......]
[Scan result: Modifiable.]
Seeing these four words, Jing Mingqiu's eyes lit up instantly. Compared to fans, TVs, and radios, a drone, an appliance that looked high-end, was much more to his liking.
Hearing Jing Mingqiu's words, Sun Heng was startled and quickly looked around the shop. "Ming Ge, when is Uncle Jing coming back? I have a drone obstacle race tomorrow morning!"
"My dad and mom went on their honeymoon, and they won't be back anytime soon. If you need it urgently, I can try?"
"Forget it," Sun Heng refused decisively, "I clearly remember the last time my drone broke, you helped me fix it. After fiddling for a long time, not only did you not fix it, but you also cracked the propeller. Uncle Jing had to put in a lot of effort to fix it!"
Seeing Sun Heng about to leave, Jing Mingqiu quickly patted his chest and guaranteed.
"As the saying goes, after three days of knowing someone, you should look at them with new eyes. Hand me the computer. If I can't fix it, I'll pay for a new one."
"It's a deal," Sun Heng agreed eagerly, "The new drone doesn't need to be too good, a Major General III series would be enough!"
Jing Mingqiu smiled and punched Sun Heng on the shoulder. "Go on, go on. I haven't even fixed it yet, and you're already eyeing your new drone."
Sun Heng chuckled, "It's not that I don't trust your skills, Ming Ge. You wouldn't bear to let me compete with an old machine, would you..."
"Alright, stop your chatter," Jing Mingqiu interrupted Sun Heng and pointed to the shop door. "How do you fix a drone? This is our family's secret technique. Hurry up and get out, and close the door on your way."
Making up an excuse to get rid of Sun Heng, Jing Mingqiu eagerly grabbed a screwdriver and completely disassembled the drone.
With the enhancement of the Level 8 Fitter skill, the modification went very smoothly. In less than two hours, all modifications were completed.
To replace the burnt-out chips, Jing Mingqiu followed the system's guidance, using scrap home appliances from the shop to manually build a miniature lithography machine and engrave three higher-precision chips.
