Infinite Rebate: I Get Richer Every Time I Spend

Cassandra carefully unzipped her backpack. Inside were neatly rolled blueprints, a tablet filled with design files, and several small mechanical components she had personally machined over the past year. She reached for the first blueprint.

Her original plan had been simple.

She would show Lucas everything.

Every drawing.

Every calculation.

Every prototype.

She would explain why her project mattered and convince him it deserved an investment.

Before she could spread the blueprint across the table, Lucas suddenly raised a hand.

"You don’t have to."

Cassandra paused.

"...Huh?"

Lucas smiled calmly.

"I don’t need to see it."

He had already learned enough about Cassandra through the system. She wasn’t just talented~she was a genuine engineering genius. More importantly, she was incredibly capable.

To be honest, even if she showed him every blueprint she had, there was a good chance he wouldn’t understand half the technical details anyway.

Engineering had never been his specialty, and he preferred leaving complicated things to people who actually knew what they were doing.

"If it’s your project..."

"I’ll invest."

His answer came so naturally that it almost sounded casual. There wasn’t even a second of hesitation.

Behind that calm smile, however, Lucas had already finished calculating everything.

He wasn’t thinking about whether the project would make money.

He wasn’t even thinking about investment returns.

He was thinking about the Rebate System.

Every dollar spent on Cassandra counted as qualified spending. Even if her project never earned a single cent, the rebate alone would make him a fortune. And if she actually succeeded?

That would simply be the icing on the cake.

He’d earn the rebate and own part of a revolutionary technology.

No matter how he looked at it...

He couldn’t lose.

Across the table, Cassandra stared blankly.

"...You..."

"You’ll invest?"

Lucas nodded.

"Yeah."

She blinked several times before asking in disbelief,

"But..."

"You don’t even know what I’m building."

Lucas chuckled.

"Then tell me."

"What exactly are you working on?"

Only then did Cassandra finally calm herself. Taking a deep breath, she carefully unfolded one blueprint across the table.

"It’s..."

"...a powered mechanical exoskeleton."

She pointed toward the detailed design.

"The goal is to create wearable equipment capable of greatly increasing a person’s strength, speed, and endurance."

Lucas raised an eyebrow.

"An exoskeleton?"

Cassandra nodded enthusiastically.

"Imagine construction workers lifting several hundred pounds without exhausting themselves. Firefighters carrying people out of burning buildings. Rescue teams reaching disaster zones much faster."

She paused before adding quietly,

"Of course..."

"It also has military applications."

The excitement on her face slowly faded.

"But that’s also where the problem begins."

Her fingers gently traced the blueprint.

"The frame has to be incredibly strong while remaining lightweight. The motors need enough power without becoming bulky, and the energy system has to last long enough to be practical."

She smiled helplessly.

"Every material that meets those requirements costs a fortune."

"I applied for research funding through the university."

"They rejected it."

Lucas remained silent, allowing her to continue.

"They believed the project would cost too much and didn’t think ordinary people would ever buy something like this. Unless it was adopted by the military, they felt it had almost no commercial value."

She lowered her head slightly.

"And honestly..."

"I understand why."

She looked toward the unfinished prototype inside her backpack.

"Projects like this burn money."

"A lot of money."

"Research teams all over the world have tried."

"Some built powerful exoskeletons..."

"...but they were too heavy."

"Others made lightweight versions..."

"...but they broke too easily."

"No one has truly succeeded."

"So..."

"My research stopped."

"I simply couldn’t afford to continue."

The campfire crackled softly between them.

For several moments, neither of them spoke.

Finally, Cassandra looked back at Lucas.

"When I found out you were the chairman of Lanai Group..."

"I thought maybe..."

"Since we’re from the same university..."

"You might at least be willing to hear me out."

She laughed awkwardly.

"I honestly didn’t expect anything."

"I definitely didn’t expect you to agree before even seeing the project."

She sat there in stunned silence.

No one had ever believed in her this much.

Not the university.

Not her professors.

Not even the companies she’d approached over the past year.

Yet Lucas had agreed almost instantly.

At that moment...

Something inside her quietly changed.

[Ding!]

Cassandra Favorability +5

Cassandra Favorability +5

Cassandra Favorability +5

Cassandra Favorability +5

Current Favorability: 50

Lucas glanced at the notification and smiled inwardly.

Not bad.

This trip to Lanai Island had already exceeded his expectations. He had only been here a short time, yet almost every girl’s favorability toward him had increased.

Compared to when he first obtained the system...

Things were moving much faster.

Cassandra finally found her voice.

"Mr. Lucas..."

"Are you really willing to invest in my project?"

Lucas nodded.

"Of course."

She clenched her hands tightly.

"I promise..."

"If my research succeeds..."

"And once the patent is approved..."

"I’ll transfer every royalty to you."

She meant every word.

Money had never been why she became an engineer.

She didn’t care about becoming rich.

She didn’t care about fame.

All she wanted...

Was to see her inventions become reality.

If handing Lucas every future profit allowed that dream to come true...

She wouldn’t hesitate for even a second.

Lucas naturally understood what kind of person she was.

People like Cassandra were becoming increasingly rare.

She wasn’t driven by greed.

She wasn’t distracted by status.

She simply wanted to create something meaningful.

Lucas genuinely admired that.

"You don’t need to think about royalties."

"The only thing you should focus on..."

"...is finishing your research."

"As long as you build what you’ve envisioned..."

"Everything else can wait."

Before Cassandra could answer, Lucas picked up his phone.

A few taps later—

Buzz.

Her phone vibrated.

She instinctively looked down.

The moment she read the notification, her beautiful eyes widened.

[Bank Notification]

Transfer Received: $15,000,000

"...Fifteen..."

"...Million?"

Her breathing became uneven.

She had expected Lucas to invest eventually.

Maybe after reviewing the project.

Maybe after weeks of discussion.

Maybe a few hundred thousand dollars to get started.

She never imagined he’d transfer fifteen million dollars immediately.

No contract.

No collateral.

No business proposal.

Lucas simply smiled.

"Use it however you need."

"If it isn’t enough later..."

"Just let me know."

Cassandra stared at him, completely speechless.

Her fingers trembled around the phone before she slowly looked back up, her eyes already turning slightly red.

"...Thank you."

She didn’t know what else to say.

Those two words carried everything she felt.

Lucas waved his hand casually.

"No need."

"We’ll discuss the project after we get back."

"But tonight..."

He glanced toward the lively barbecue.

"Forget about work."

"We’re here to relax."

"Go enjoy yourself."

Cassandra smiled and nodded.

"...Okay."

As she hugged the phone to her chest, Lucas heard the familiar system notification.

[Ding!]

Host spent: $15,000,000.

Calculating rebate...

A second later—

[Congratulations!]

Rebate received: $150,000,000.

Lucas’s lips curved upward.

Ten times.

Exactly as expected.

His investment hadn’t cost him a single dollar.

Instead...

His wealth had just increased by another one hundred and fifty million.

Just as he finished checking the notification, a familiar voice called from behind.

"Mr. Lucas!"

Maya came running toward him, waving excitedly from the campfire.
