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

Paul quickly swerved to the front of the car on the high-speed right bend, his eyes fixed on the braking curve.

Still zero.

Chen Lang's right foot was still pressed against the switch.

He only released the power and stepped on the brake when he was close to the last braking indicator.

The front of the car suddenly dipped.

The outer suspension is adjusted synchronously, and the torque of the four wheels is redistributed according to the steering angle.

The speed dropped rapidly from 250 to 170, and the steering wheel was immediately turned.

U9 cuts into the apex of the bend while hugging the red and white shoulder.

The right tire is less than half a palm's width from the edge of the track.

The car body did not sway sideways, nor did the rear end swing outwards; it simply followed the trajectory left by the front end and cleanly entered the bend.

The tires remained firmly gripping the ground.

The moment the turn line opened, Chen Lang straightened the steering wheel and stepped on the accelerator again.

The silver-gray car body shot out from the right bend, and its speed climbed back up.

Paul stared at the four-wheel curve, his electronic pen hovering above the tablet, not falling for a long time.

From takeoff and landing to full acceleration, then to extreme braking and high-speed cornering, the four stages of operation are almost seamless, yet none of the actions interfere with each other.

More importantly, the stabilization system has been shut down.

The entire segment just now was completed by Chen Lang himself.

Is it over?

[250 km/h on the straightaway, 170 km/h on the curve, and the car didn't even sway?]

Where is the person who was delivering water on a shared bike?

Su Niannian's shared bicycles have applied to withdraw from the testing field.

Why not float? Wouldn't it look cooler to go sideways?

[The tires didn't break, and the wiring wasn't lost, so how could he drift?]

Drifting is for controlling the car, not for showing off on every corner.

The second bend connects to the third bend.

The U9 swerved left and right on the track. As soon as the front of the car left the right shoulder, the next turn went directly into the left apex of the corner.

Deceleration, turning, and acceleration—the three actions were executed flawlessly.

The wheels were firmly gripping the ground.

The supercar with over a thousand horsepower glided smoothly along the predetermined route.

The second lap timer pops up.

Paul stared at the screen, then looked up at the track. The time was four seconds faster than predicted, all four seconds coming from the corners.

"No drifting." Paul swiped his finger across the data replay. "Full grip during the corner, with a yaw angle of less than two degrees."

He quickly flipped through the curve chart.

"The torque distribution of the four motors was split into four independent forces. The inner front wheel reduced torque, the outer rear wheel increased torque, and the angle at which the front of the car cut into the apex of the curve exceeded the system's calculated value."

Paul's Adam's apple bobbed.

"Manual vector control".

Zhou Mingyuan leaned closer to the screen.

"What do you mean?"

Paul placed the tablet face down on the monitoring table.

"This car has a four-motor independent torque distribution system, with the computer making thousands of corrections per second. He turned off the assist and forcibly separated the force from the four wheels using only the accelerator and steering wheel."

"And the results?"

Paul's jaw tightened.

"It crushed the computer."

Zhou Mingyuan took half a step back.

Su Niannian turned her head away, her jaw loosening.

"Say it again?"

Paul kept his eyes on the track and didn't reply.

Chen Lang's voice came through the communication channel, tinged with a slight static.

"Paul, call the water truck to water the plants."

Paul raised his gaze.

"What are you going to do?"

"Rainy days don't discriminate against anyone." Chen Lang leaned back in his bucket seat, his knuckles tapping the edge of the steering wheel.

"Water half of the track, leaving the right side dry and the left side wet."

"Mixed wet and dry roads?"

"Um."

Paul took off his hat and wiped his forehead with his palm.

"Wet and dry surfaces are two separate systems. In the same corner, the grip difference between the wet and dry sides is three to four times. With the four wheels having different friction coefficients, the car will lose control and fishtail in the middle of the corner."

"Water it."

Paul grabbed the walkie-talkie.

"The water truck starts and waters the left lane."

The water truck's nozzles were turned on, and the water jets swept across the left half of the track.

The bluish-gray asphalt absorbed the water stains, darkening in color. The dividing line between the dry road surface and the wet area on the right half extended straight.

[Was it watered? The pavement is half-dry and half-wet?]

[Simulating torrential rain on mountain roads! This is the kind of terrible road condition the Nine Bends road will be like on race day!]

[Taking a high-speed corner through the wetlands, surely it'll drift this time?]

I bet a month's membership that I'll definitely drift the tail end this time.

U9 departed from the departure line.

Third lap.

At the end of the long straight road, the speed exceeded 220 km/h.

Before entering turn one, the left wheel presses against the water film.

Paul gripped the edge of the monitoring console with both hands.

On the tablet screen, the grip of the left front wheel dropped sharply, while the two right wheels remained firmly gripping the dry road surface.

The friction coefficient of the four tires has split in two.

"The traction on the left side drops sharply," Paul said, his pace quickening. "The yaw moment will pull the front of the car to the left—"

The sound stopped abruptly.

U9 vehicle body offset.

The rear of the car swung out to the right, and the entire car cut 45 degrees around the center of the bend.

The tires rolled over the road surface, and the high-frequency friction sound pierced the track.

White smoke rose from the rear wheel, leaving two curved tire tracks on the wet road surface.

The silver-gray body was hanging diagonally in the curve, its front end firmly aimed at the exit, and its four motors emitted four different frequencies of whistling.

Su Niannian loosened her grip on the guardrail and her back collided with the construction vehicle.

"he--"

Paul stared intently at the screen, the data refreshing rapidly.

The left front wheel's torque is reduced to zero, the left rear wheel outputs braking force in the opposite direction, the right front wheel is driven by 30% of its power, and the right rear wheel unleashes its full power.

Four motors, four directions, four outputs.

The body yaw angle is capped at 42 degrees and will not be increased further.

The supercar with over a thousand horsepower glided along the curve.

The trajectory was perfectly aligned with the set route, without deviating even slightly from it.

Exiting the bend.

The car body is straightened.

There was no repeated attempts to correct the direction, nor any frantic scrambling after slipping.

The rear of the car cleanly and decisively gripped the center line.

The accelerator was fully engaged. The U9 lunged towards the next straight section of the road.

Paul pulled up the replay and slowed it down to a quarter speed.

At the drift start point, the torque curves of the four motors change synchronously. The four-way distribution is completed at the same moment.

"The throttle depth changed 0.3 seconds before entering the corner." Paul's electronic pen hovered above the screen, remaining still.

"Press the brake with your left foot and the accelerator with your right foot to send a positive thrust pulse to the right rear wheel."

"The rear of the car was pushed out by the pulse, causing it to oversteer. Anyone else would have rolled over here."

"Turn the steering wheel 15 degrees in the opposite direction at the same time."

Paul's throat tightened.

"He directly disassembled and controlled the four motors. He could retract to the left, release to the right, pull forward, and push backward. The vehicle could slide sideways, and he had complete control over the grip of all four wheels."

Zhou Mingyuan looked at the mechanical breakdown diagram on the screen.

"The U9's torque vectoring control system is designed by the manufacturer to prevent loss of control."

Paul looked away from the screen.

"He reversed the process by using the anti-runaway system to actively create and maintain the drift."

Zhou Mingyuan frowned.

"System permission?"

"Not allowed." Paul pulled up the underlying data.

"When driver assistance is turned off, motor control is transferred to the accelerator, brake, and steering wheel. These three ports provide a maximum of three dimensions of control variables."

"He just gave four independent torque outputs."

Paul paused for a moment.

"The force applied to the brake pedal has become the fourth variable."

"The left-foot brake is not a simple opening and closing; it provides braking force down to a percentage and forcibly distributes it to the front and rear axles."

"The braking force, throttle depth, and steering wheel angle are combined, and the four motors receive four independent commands simultaneously."

Paul closed his tablet and looked at the track.

The U9 plunged into the second wetland bend.

The car body swayed sideways again.

Fifty-three degrees.

Half of the car body was pressed against the wet ground, and the other half was stuck on the dry road surface. The two road conditions were cut in the middle of the car body, and the grip of the left and right wheels differed by nearly four times.

Under normal circumstances, the car would have already lost its balance and spun around in place.

U9 gripped the ground tightly.

With the 53-degree yaw angle locked, the vehicle smoothly advances along the curve.

White smoke rose from the rear wheels, mixing with the water vapor left by the water truck, leaving a grayish-white mist on the track.

The camera feed from inside the vehicle is switched onto the monitoring screen.

Chen Lang leaned back in the bucket seat, his shoulders against the backrest.

My left foot rests on the brake pedal, with the ball of my foot rising and falling by less than two centimeters. The depth of my right foot on the accelerator changes continuously with the curvature of the curve.

With slight adjustments to the steering wheel, the wrist movements perfectly matched the distribution of water film on the road surface.

From an external perspective, this is a car on the verge of going out of control, skidding sideways at high speed.

On the data panel, the output power of all four motors is under control.

Shen Qingci stared at the laptop, her thumb pressing down on the edge of the touchpad.

The curves on the screen are smooth and fluid. Every fluctuation of the four torque lines is precisely timed to occur before any changes in road surface feedback.

"Anticipated in advance." Shen Qingci's gaze locked onto a data point. "The wet/dry dividing line hadn't even touched the left front wheel before the accelerator was released."

Paul walks closer to the screen.

Clench your molars and tense your cheekbone muscles.

"The human reaction limit is 0.15 seconds." Paul stared intently at the data. "His prediction of the road surface change was 0.2 seconds ahead of time."

"He was not responding to road feedback."

Paul took off his glasses and rubbed his temples.

"He's giving instructions to the road surface."

Ye Xingyu stood beside the construction vehicle, her hands gripping the door frame tightly.

"Is this still considered human reaction speed?"

Paul did not answer.

He reopened the tablet and opened the driver evaluation section.

The phrase "under observation" was directly deleted.

The cursor blinked in the blank space, but no new evaluation was typed.
