Wan Xinyue's Exclusive GTI Plan

Early the next morning.

The early spring sunlight pierced through the thin mist, scattering over the sparkling surface of the East Lake.

After ending his cozy night alone with Li Xingya at the landscape villa, Su Bai drove back to the East Lake private club bright and early, feeling completely refreshed.

Today, he had an important and incredibly fun hardcore task—fulfilling his promise to Wan Xinyue by personally building the most ferocious performance hot hatch in all of Jiangcheng for her.

Taking the elevator straight down to the luxurious second-level underground garage, Su Bai walked directly to the innermost section. There lay a fully transparent, dust-free tuning workshop built to the standards of a top-tier F1 team's pit garage.

Resting quietly on the hydraulic lift in the center of the workshop was a brand-new, eighth-generation Volkswagen Golf GTI.

As the totem of affordable performance cars, the GTI's foundation was absolutely unquestionable.

However, this factory-spec daily driver with only two hundred-plus horsepower clearly wasn't worthy of Wan Xinyue's monstrous track talent, nor did it match Su Bai's grand style.

Over the past few days, thanks to the exceptional execution of Xia Lin and his butler Zhou Jialu, the long list of top-tier tuning parts Su Bai had ordered had arrived consecutively via international air freight.

At this moment, the shelves on one side of the workshop were piled high with cardboard boxes bearing the logos of various top-tier tuning brands: forged pistons and connecting rods, an oversized Garrett turbo, a full set of Akrapovic titanium exhaust, competition-grade KW coilovers... everything one could possibly need.

Beep.

Su Bai pushed open the glass door and walked into the workshop, only to be surprised to find someone already inside.

Moreover, they had arrived even earlier than him.

The older sister, Wan Xinyue, had swapped her usual fitted dresses for a sharp, dark blue, slim-fit mechanic's jumpsuit today.

Due to her petite yet extremely voluptuous figure, this jumpsuit, which was supposed to look rugged, was forcibly stretched into a pulse-racing tightness.

The zipper was barely pulled up to her chest, making her proud D-cup curves look ready to burst out.

At this moment, the usually quiet and introverted older twin was staring intently at the gleaming metal mechanical parts on the shelves. The undeniable flame of excitement, one that only a fanatic car enthusiast would possess, danced in her eyes.

Beside her, the younger sister, Wan Xinyan, was placing several delicate insulated food containers on the workshop's rest table.

"Brother Su Bai, you're here!"

Seeing Su Bai enter, the lively Wan Xinyan immediately greeted him like a cheerful little sparrow, affectionately taking his arm. "My sister and I woke up early. She was so obsessed with this car that she dragged me down here right at dawn. I guessed you probably hadn't eaten breakfast yet, so I went to the kitchen and personally made you some pan-fried buns and pork and century egg porridge. Eat it while it's hot!"

"Our Xinyan is the most thoughtful." Su Bai smiled and pinched Wan Xinyan's slightly chubby cheeks, then walked over to the rest table and sat down.

Hearing Su Bai's voice, Wan Xinyue finally tore her gaze away from the set of forged wheels with great reluctance.

Blushing, she walked over to Su Bai, poured a cup of warm soy milk, and handed it to him. Her voice was soft and sweet, "Good morning, Brother Su Bai. These parts... they all look incredibly impressive."

"Of course they are. This is the heart I custom-tailored specifically for your hot hatch." Su Bai took a sip of the soy milk, enjoying Wan Xinyan's attentive feeding while pointing at the GTI. "We'll start working right after breakfast. Today, we'll first reinforce the engine internals, and then swap in that massive turbo."

After finishing the loving breakfast carefully prepared by the twin stars, Su Bai changed into a clean mechanic's uniform, put on his gloves, and walked over to the lift.

As the Car Tuning Master Level skill fully activated in his mind, Su Bai's gaze instantly became deep and focused.

In his eyes, the GTI's complex mechanical structure became as clear as if it were transparent. The torque of every screw and the routing of every pipe formed an extremely precise three-dimensional model in his brain.

"Xinyue, hand me that size-ten ratchet wrench," Su Bai reached out his hand without looking up.

"Okay."

Wan Xinyue skillfully and accurately took the size-ten wrench from the expensive Snap-on tool wall and placed it steadily into Su Bai's hand.

"Oh?" Su Bai turned his head, looking at her in slight surprise. "You know these tools?"

"Before... back in high school when I played racing simulators, I used to watch a lot of documentaries about mechanical principles and tuning. I just know a tiny bit." Wan Xinyue felt a little shy under Su Bai's gaze and explained softly.

Looking into her clear eyes full of a thirst for knowledge, Su Bai's heart couldn't help but stir.

He realized that this girl, Wan Xinyue, not only possessed stunning track driving talent, but deep in her bones, she also had a profound interest in this kind of mechanical tuning filled with the smell of motor oil and the clashing of steel.

"Want to try doing it yourself?" Su Bai suddenly put down the wrench and looked at her with a half-smile.

"Can... can I? These parts are so expensive. What if I break them..." Wan Xinyue was both tempted and a little timid.

"With me here, what are you afraid of? If it breaks, we'll just buy a new one."

According to the system's cashback rules, he definitely couldn't break things on purpose; that would be too wasteful.

However, letting Yueyue use them for practice was a different story.

Without accepting any refusal, Su Bai stuffed a torque wrench into her fair and delicate little hands, then walked up behind her with extreme naturalness. His tall frame pressed against her back, his broad chest almost completely molding against her slender back.

Su Bai reached out his hands, grasped Wan Xinyue's hands from behind, and guided her to lock the wrench onto a screw on the engine cylinder head.

"The beauty of mechanics lies in its absolute precision." Su Bai lowered his head, his warm breath brushing against Wan Xinyue's sensitive ear. His deep voice carried a bewitching magnetism. "Feel the resistance coming from the wrench. When you hear a click, it means the torque has reached the set standard value."

Enveloped in Su Bai's arms in such an extremely intimate, almost half-embracing posture, Wan Xinyue's cheeks instantly flushed crimson. Even her shapely legs, wrapped in the slim-fit jumpsuit, grew slightly weak.

But when her hands, under Su Bai's guidance, truly began to exert force and she felt the mechanical feedback of that screw biting into the threads inch by inch...

That natural perception of mechanics deep in her bones was instantly awakened.

Click.

A crisp metallic clinking sound rang out.

"Right, exactly that amount of force," Su Bai released his hands, a hint of appreciation flashing in his eyes. "Try tightening the next one yourself."

Wan Xinyue took a deep breath, suppressing the fluttering in her heart, and her eyes grew focused.

Holding the torque wrench, she aligned it with the next screw and applied force with her arms.

Although the entire movement still looked a bit unpolished, the rhythm of her exertion and her perception of the mechanical resistance were surprisingly precise.

Click.

Another crisp sound; perfectly up to standard.

For the entire morning that followed, the crisp clinking of tools echoed throughout the dust-free workshop.

Su Bai was surprised to discover that Wan Xinyue was not only an incredibly fast learner, but her hands were also exceptionally steady.

Whether it was dismantling the complex intake manifold or sanding down tiny metal burrs, she could immediately grasp the trick to it with just a few pointers from Su Bai, executing the tasks like a true professional.

Her younger sister, Wan Xinyan, sat obediently off to the side. Sipping on her juice, she used her phone to record this highly hardcore yet somewhat romantic scene.

"Xinyue, with a talent like yours, it would be an absolute crime if you didn't become a race car driver or a top-tier mechanic," Su Bai remarked with genuine admiration. He looked at the pretty girl beside him, noting the fine bead of sweat on her forehead and the small smudge of gray engine oil on her cheek.

"As long as I can stay by your side and help you modify this car, Brother Su Bai, I am already completely satisfied."

Wan Xinyue set down her tools, tilted her pure and stunning face—still breathtaking despite the slight oil stain—and gave Su Bai a radiant smile.

In this modification workshop, heavy with the scent of steel and motor oil, a terrifyingly powerful hot hatch was quietly forging its steel heart through the seamless teamwork of the pair.
