A live stream that dramatically transformed a depressed schoolgirl shocked netizens across the count

The tailgate of the second heavy transport vehicle lowered, and the spare tire, smelling of fresh rubber, was pushed out.

The hydraulic jack lifted the gray-silver car body.

The pneumatic wrench spun rapidly, removing the bolt.

Several engineers surrounded the left rear wheel, removing the old tire, replacing it with a new one, and connecting the air pump.

The airflow rushed into the tire, and the tire bead snapped into the rim, producing a dull thud.

After more than ten minutes of work, the old tire was stuffed into a thickened storage bag, and the valve assembly was placed separately into a transparent evidence box and labeled with a number.

Representatives from the transport company, the project manager, and the user took turns picking up markers and signing their names at the intersection of the seals.

After the 15-minute pressure maintenance process was completed, the pointers on the four independent tire pressure gauges stopped in the green standard range.

The chassis scanning equipment slid under the vehicle body, the progress bar on the detection tablet reached its maximum, and a green light indicating that the test was successful appeared.

A man in his forties stepped out of the engineering team.

He took off his oil-stained work gloves and stood in front of the live broadcast sphere.

"Hello everyone, my name is Zhou Mingyuan, and I am the chief engineer in charge of the pre-match support project for the Yangwang U9 competition."

He placed his identification badge and handover documents together in front of the camera.

"From the moment the vehicle leaves the transport compartment, I am responsible for all inspections, replacements, tests, and parameter adjustments."

"The left rear wheel and valve assembly that just showed an abnormality have been sealed and will be sent to a third-party organization for re-inspection later."

Zhou Mingyuan stepped aside, making room for him.

A foreign man wearing black-rimmed glasses stepped forward.

He was wearing a dark gray engineering uniform, with a technical badge hanging on his chest, and an engineering tablet tucked under his strong forearm.

"This is Paul, the technical advisor for the vehicle being tested."

"He is responsible for driving data analysis and also has the authority to stop the test if the vehicle is in an abnormal state."

Paul nodded toward the camera.

His gaze passed over Zhou Mingyuan's shoulder and lingered on Chen Lang for two seconds.

Chen Lang leaned against the bluestone courtyard wall, his black windbreaker collar open, the silver cross swaying in the wind.

He held a steaming cup of soy milk in his left hand and half an egg pancake in his right. He took a bite, and steam escaped from the corner of his mouth. His hair was messed up by the wind.

By any measure, this outfit has nothing to do with the professional drivers in Paul's record book who wear bespoke racing suits and have a full support team.

How many hours of track training did Mr. Chen receive?

Paul gripped the tablet tightly, his tone stiff.

Chen Lang chewed on the biscuit, his Adam's apple bobbing as he swallowed.

"I haven't calculated it."

"What about this car?"

"First time touching it."

Paul frowned, pressed down on his wrist, and the stylus drew two lines on the screen.

"The vehicle has high power and the driving style is different from ordinary sports cars."

"Those who are encountering it for the first time need to complete basic training."

"how long?"

"Minimum three days."

Chen Lang raised the hand holding the soy milk cup and waved it at the gray-silver U9.

"The competition starts the day after tomorrow."

"Therefore, I suggest changing the driver."

Paul closed the tablet and tilted his chin up.

The wind swept through the alleyway, swirling up the dry, fallen leaves on the ground, which brushed against Paul's overalls.

The breathing of the few people at the courtyard gate mingled, but no one spoke.

Su Niannian flicked her wrist, and the heavy metal wrench slammed into the toolbox.

The crisp sound of metal clashing echoed at the courtyard gate.

She took two long strides closer, her jawline sharply defined, her eyes fixed on Paul.

"The car hasn't even started moving, and you've already switched the driver?"

Paul pushed up his glasses.

"The track does not accept last-minute decisions."

"Expensive vehicles, live streaming cameras, and crowds of onlookers can easily lead drivers to overestimate their abilities."

His gaze remained fixed on the tablet as he spoke, not glancing at Chen Lang even slightly.

A rich young master borrowed a sports car worth tens of millions, brought his live-streaming team, and set up a grand spectacle, then chose a rainy mountain road race to attract attention.

Paul has seen too many people like this; before the car door is even fully closed, the promotional material has already been posted all over social media.

After finishing the last sip of soy milk, Chen Lang accurately tossed the empty cup into a trash bag two meters away.

"Engineer Zhou."

"Mr. Chen, please speak."

"Check the right front wheel again."

Zhou Mingyuan turned to look at the detection screen.

All data for all four tires remained within the green standard range.

Paul lifted his eyelids.

"There is no warning light on the right front wheel."

"I know."

Chen Lang raised his hand, bent his index finger at the knuckle, and pointed at the black inspection mat under the right front wheel from a distance.

"The watermark it left was wider than the other three."

The staff member looked down to examine it.

Four vehicle inspection mats were laid on the bluestone slab.

Water overflowed from the edge of the tire under the right front wheel, leaving a thin, long mark about half a palm's width along the tire sidewall.

The engineer crouched down and sprayed leak detection fluid all over the connection between the tire and the rim.

The foam dissipated, and not a single bubble could be found.

Paul looked away, his brows and eyes relaxing.

"It's just cleaning fluid residue."

Chen Lang ignored him, turned his wrist, and pointed to the inside of the wheel hub.

"Turn half a circle."

The car body was lifted up with a jack.

The engineer, wearing gloves, gripped the right front wheel and pushed it hard to turn.

As the wheel hub turned 180 degrees, a section of transparent plastic film peeked out from the inner drain hole, with a few drops of murky water clinging to its edge.

That was a temporary protective film applied before shipping; a section was torn off when it was removed.

The diaphragm blocked the drain hole, and the accumulated cleaning fluid mixed with dust got stuck inside the wheel rim.

After driving, these gravel particles will be directly rolled into the brake discs.

The engineer pinched the film and pulled it out, pulling out a long strip. He then turned around and carefully touched the tire again.

Zhou Mingyuan added information to the record sheet.

"The protective film residue on the right front wheel has been removed."

Paul's arm, which was holding the tablet, stiffened at his side, his Adam's apple bobbed up and down, and his knuckles, which were gripping the stylus, pressed tightly against the edge of the screen.

Chen Lang leaned against the courtyard wall and took the second cup of soy milk from Bai Weiwei.

"Don't rush to change drivers."

He inserted the straw.

"At least wait until I get into the car."

Su Niannian turned her face away, her shoulders shaking several times, unable to suppress the smile on her lips.

The live stream chat was filled with comments.

[Paul: The data didn't trigger an alarm. Lang Ge: The watermark on the ground did.]

[Before even getting on the bus, the technical consultant submitted a wrong answer.]

[Brother Lang was holding a glass of soy milk, but his eyes were scanning the entire car.]

Did Paul just treat him like a pampered prince posing for a photo?

Paul scanned the live stream screen and closed the comment window.

"Observing details and driving a vehicle are two different things."

"right."

Chen Lang nodded.

"So you're in charge of continuing to observe, and I'll be in charge of driving."

Zhou Mingyuan suppressed a smile and held the independent storage terminal in front of the camera.

"The vehicle will remain in its original factory condition."

"The adjustment records generated today will be synchronized to the third-party monitoring platform."

"The operators, modification times, and data before and after modifications are all documented."

Shen Qingci stepped forward, holding the evidence terminal.

"In-vehicle system version".

The engineer announced the version number and turned the testing page towards the camera.

"The factory-released version does not include the track tuning program."

"Remote access permission".

"Closed. Local project interface will be retained during testing."

"Data ownership".

"A copy should be kept by the third party, the engineering team, and the car owner."

Shen Qingci checked the number on the page and stored the final report in the evidence database.

"You can sign."

Gu Qingshang took the electronic pen and wrote his name at the end of the handover confirmation letter.

Chen Lang held the car door shut but did not get in.

"First, conduct a test start-up on the spot; don't drive it out of the alleyway."

Zhou Mingyuan nodded.

"Do as he says."

Paul glanced at Chen Lang.

The young man, whom he had just categorized as a show-off, always managed to address the core issues, from tire warnings to residual protective film.

But what a racetrack requires is driving.

Finding a thin film proves nothing.
