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

The live stream stopped at the frame where the flower stand crossed the street corner.

The drumsticks struck the drumhead, and blue and white confetti flew across the lens.

The suspended sphere cuts off the flow, and the mechanical support retracts inward.

Chen Lang caught it and casually stuffed it into the side pocket of his windbreaker.

The number of online users has dropped to zero.

The sounds of drums, hawkers' cries, and children chasing flower stands filled my ears again.

Chen Lang turned around and followed the others.

Su Niannian walked at the front of the line, counting the lunch menu on her fingers.

"Steamed chicken in a clay pot, cured pork ribs, cold tree flower salad, and stir-fried greens."

After counting once, she turned and glared at Chen Lang.

"Hey Chen, you're making a racetrack model this afternoon, so don't drink alcohol with lunch."

"Anyone who dares to drink will be given a drunk driving lesson with a spatula."

Chen Lang put his hands in his pockets and stepped across the puddles on the bluestone path.

"Coach Su's business is quite extensive; he handles everything from kitchen operations and security to racing supervision."

"Shut up."

Su Niannian patted her apron.

The iron spatula hidden inside made a crisp sound when it struck something.

Bai Weiwei carried the packaged milk fan and flower cakes and distributed a portion to everyone.

She walked to the fork in the road and straightened the road sign that had been blown askew by the wind.

"We have mushrooms at home, so we can stir-fry a plate whenever we want."

"No need."

Gu Qingshang was still looking down at the event documents, speaking gently, without stopping.

"Before the competition, no one is allowed to eat wild mushrooms of unknown origin."

"I don't want to add another case of collective hallucination to the hospital consultation records."

Su Niannian paused in her steps.

"Then let's keep it to feed Xiao Yunlong."

Ye Xingyu, carrying the folder of documents, followed beside her and finally burst out laughing.

Shen Qingci lagged behind the group, and as she crossed the stone bridge, her pace slowed.

Shen Qingci glanced down at the pre-match data groupings on the screen, then looked up again.

"The weather and road condition data have been archived; shall we proceed directly to model making this afternoon?"

"Um."

Chen Lang stepped through the puddles on the stone path, his Martin boots kicking up water droplets that scattered on the moss on both sides.

"Let's go back to the courtyard for dinner first. After dinner, we'll quickly build the digital model of the winding mountain road, track the rain belt at night, and monitor the weather radar in the early morning."

"Okay." Shen Qingci nodded.

After the two finished speaking, they crossed the stone bridge and followed the footsteps of the people in front of them.

On both sides of the bluestone alleyway were scattered tie-dyed fabrics. Bai Weiwei led the way, carrying fresh flower cakes and wrapped milk fan in her hands.

Gu Qingshang swiped his phone screen; the event approval directory had just been updated.

"The application for track closure has entered the joint review stage, with medical, fire protection, insurance, and third-party timing processes proceeding simultaneously."

"The other party must submit a list of training vehicles, drivers, and support teams by 6 p.m. tonight."

Her high heels stopped at the corner of the alley, her gaze fixed on the system announcement entry.

"Xiao Yunlong has requested to hold a closed training session tonight."

Ye Xingyu, holding the file bag, peered forward.

"Is he going to run into the rain ahead of time?"

The application stated that the project was for road safety testing.

Gu Qingshang scrolled down the page.

"It comes with a large water truck, two training vehicles, and four sets of rain tires."

Su Niannian turned around, carrying the condiment bottle.

"Is this what you call a security test?"

"They fill mountain roads with water using water trucks, then drive supercars down them, and they call that safe?"

Chen Lang continued walking, stepping over two slippery stone steps.

"With all the necessary paperwork in place, the road sealed off properly, and rescue efforts readily available, no one could stop him from cleaning up the mountain roads."

Su Niannian quickly followed beside her.

"Aren't you going to go to the site and keep an eye on things?"

"I'm not going."

Chen Lang casually kicked aside a broken, withered branch by the roadside.

"He practices his own, we practice ours."

Su Niannian shook the corner of the apron in her hand twice.

"They've run it thirty-seven times, now they're going to test the limits in the rain."

"You're just talking about which way the entrance to the winding road faces; aren't you really going to go and see for yourself?"

Chen Lang put his hands in his pockets, turned his head, and laughed out loud.

"The entrance faces the mountain."

"The exit faces down the mountain."

"If any one of these conditions is missing, the competition cannot be held."

Su Niannian pressed down on the handle of the iron spatula inside her apron.

Chen Lang took a small step back, his gaze falling on the terminal Shen Qingci was holding.

"Shen, you need to keep an eye on your family's chef who's always ready to cook."

Shen Qingci put the terminal into the inner pocket of her coat, leaving no room for him behind.

"She has a reasonable question."

Chen Lang stopped and stared at the corner of the courtyard wall that had been exposed at the end of the alley.

"OK."

"After we finish eating, I'll pull out the topographic map and explain it to you."

Su Niannian loosened her grip on the spatula and turned to Bai Weiwei.

"Make an extra cold tree flower salad for lunch today, and settle the score with him after we've eaten our fill."

A gust of wind blew along the alley, lifting the two indigo tie-dyed cloths at the front, carrying the dampness of the grass and trees of Cangshan Mountain.

At the foot of Cangshan Mountain, a temporary base.

The live stream recording was frozen at the last frame.

In the picture, Chen Lang is standing by a puddle, with a dead leaf stuck at his feet.

He didn't use blueprints or set up surveying equipment. After a few casual words about the water film effect, he turned around and went to browse the stalls on the street.

Ah Biao pressed the rewind button, and the same video was played again.

The long table was covered with training reports from the thirty-seventh training session, which involved a series of twists and turns.

Braking points, cornering speeds, gear positions, and throttle openings are all marked with numbers using markers of different colors.

Three secondary screens continuously played clips of Chen Lang's video.

Staff took screenshots at the last second, embedding six reverse slopes, three waterlogged areas, and publicly available altitude data into the track structure.

In the bottom right corner of the screen, the seven small connection icons turn gray one after another.

The outsourcing company's project manager sent back the text.

"All seven accounts have been exposed."

"The other party did not disclose parameters such as tire pressure, suspension, energy recovery, and power distribution."

"Currently, the available information is limited to publicly available terrain data, making it impossible to determine the actual tactics."

Ah Biao loosened his collar.

The air conditioner's cold air blew into my work clothes, but I was still sweating profusely from my forehead.

"After raising seven tires and asking around, all I got in return was, 'Are the tires afraid of water?'"

The project manager disconnected the connection.

Xiao Yunlong sat in front of the main screen, scrolling the mouse wheel back and forth.

The clips of Chen Lang speaking made several people rewind to the beginning.

Floodwater.

Reverse slope.

The water film supports the tire tread.

The dry braking point was overturned.

Xiao Yunlong leaned back in his chair and tapped the close icon.

"He's never run the winding road."

Ah Biao delivered the newly printed race track map to his desk.

"Weather model update".

"The main rain belt entered the mountain half an hour earlier, and the No. 6 and No. 9 bends were the first to be flooded."

"Bend No. 12 is close to the cliff, and there is a risk of loose rocks rolling down when strong convection passes through."

Should the publicly available training plan be revised?

Xiao Yunlong did not answer, but opened the cabinet door at the bottom of his desk.

He tossed the black-covered folder directly onto the desktop.

The sheets of paper spread out along the wooden tabletop.

For six years, all the accident records from rainy nights at Jiuquwan have been stored inside.

Rainfall time, water depth, drainage time, point of vehicle loss of control, angle of impact with guardrail, and time it takes for rescue vehicles to arrive.

Every page was completely covered with areas written in red pen.

The sign next to Bend 6 reads "Insufficient lateral drainage".

The ninth bend is marked with the words "outer side subsidence".

Three thick red lines are drawn below Bend 13, and photos of the crash site are posted next to it.

Ah Biao flipped through the two files, pressing his thumb against the serial number in the lower left corner of the page.

That number belongs to the road maintenance unit, and an internal archive stamp is affixed to the lower right corner.

"Where did you find these?"

"Mountain Road Maintenance Team"

Xiao Yunlong pulled out the drainage profile of Bend 6 and superimposed it on top of the data from the 37 dry track sections.

"Not a single word of the publicly disclosed training plan may be changed."

"The video recording is still kept."

"If Ye Xingyu gets her hands on the original data, let her continue studying the records of the thirty-seven dry land trials."

Ah Biao swallowed a mouthful of saliva.

"What if the maintenance team investigates the leak of internal data?"

"Once the race is over, who will bother with the accident files from years ago?"

Xiao Yunlong picked up a red pen.

He traced a line along the guardrail on the outer edge of Turn Six.

"Chen Lang knows how rain can disrupt the braking position."

"But he didn't know how deep the water was on each section of the route, let alone how the water was stored up or how long it would take for it to leak out."

"Theory can teach him how to make wheels slip."

The pen tip pricked a hole in the red paper.

"This stack of stuff can tell me exactly at which meter the car will start to slide."

Ah Biao stared at the images of the wrecked vehicles on the table and swallowed the rest of his words.

"Are you setting off on time tonight?"

Xiao Yunlong clicked on the monitoring screen on the right.

Inside the enclosed warehouse at the foot of the mountain, two spare training vehicles were suspended in the air on a lift.

The mechanic is removing the regular running tires and replacing them with rain tires that have long grooves in the tread.

The heavy-duty water truck is parked inside the roller shutter door, the water tank is filled to the top line, and the hose is fastened to the rear of the vehicle.

The approval process for the closed training venue is stuck in the background, missing only the final permit stamp.

"Permission granted, release the water."

"The first trip was conducted at 60% power, recording the extent of the flooding."

"The next trip will be 80% complete, targeting the new braking point."

"On the last trip, we'll test the tires' limits."

Ah Biao looked at the clock hanging on the wall above.

"The Lamborghini that participated in the race underwent a traffic inspection today, and the team insists on doing a detailed adjustment of the car individually."

"No main racing car tonight."

Xiao Yunlong pointed to the two backup cars in the surveillance footage.

"Data was collected using prototype vehicles with the same wheelbase and similar powertrains."

"All parameters are stored in a standalone device; cloud transmission is prohibited."

"Chen Lang was able to find out about the outsourcing company online using seven different accounts, and he could also find out about this company's records online."

After he finished speaking, he folded the cross-sectional diagram of Turn Six into four pieces and put it into the breast pocket of his racing suit.

"The water truck should go first."

"I'll run it myself today."

The base personnel walked in rows toward the workshop.

The laser printer outputs new test sheets in sequence, technicians check tire pressure readings, and the rescue and first aid team changes gear and stands by.

Ah Biao tidied up the accident records on the table and walked to the stand-alone encrypted scanning cabinet.

A piece of white paper was swept underfoot by the wind.

That was a summary record of last year's routine road maintenance.

The cover plate at the No. 6 drainage location in the Nine Bends area has been replaced.

The date of the overhaul was eight months later than the last year that the accident records were filed.

Ah Biao bent down to pick up the paper, his eyes scanning downwards.

"Young Master Long, there was a drainage emergency repair at Bend 6 last year."

Xiao Yunlong accepted the form.

The maintenance instructions end with only one column of notes.

"Replace the damaged cover plate and dredge the original trench."

He simply took a picture of the record in the original spot.

"Replacing the board doesn't change the drainage cross-section."

"Open with the original data."
