The Billionaire's Cashback System

Chapter 1: The Zero-Balance God

"Ethan, let’s be realistic. Your monthly salary can’t even buy a single square meter of the tile in this restaurant."

Chloe didn't look up from her phone. Her voice was flat, completely devoid of the warmth they had shared over the last two years. Sitting across from her, Ethan held the velvet ring box tightly in his pocket. His knuckles were white.

"I got a promotion text this morning, Chloe. I’m a senior analyst now," Ethan said, trying to keep his voice steady. "In three years, I can manage a down payment on a studio apartment—"

"A studio apartment?" Chloe finally looked at him, a cold laugh escaping her lips. "Oliver bought a luxury villa in the North District yesterday. He didn't wait three years. He just swiped his card."

Right on cue, the glass door of the private dining booth pushed open. Oliver stepped in, his tailored suit immaculate, a gold Rolex gleaming under the restaurant's crystal chandelier. He didn't even look at Ethan as he walked over and casually placed a hand on Chloe’s shoulder. She didn't pull away.

"Ethan, buddy," Oliver smiled, though his eyes were mocking. "Don't make it harder than it needs to be. A man without capital shouldn't try to hold onto a woman who belongs in high society. Waiter! Bill, please."

The waiter arrived instantly, presenting a leather folder. "Sir, the total for the premium Wagyu course and the vintage wine is $3,200."

Oliver pulled out a shiny black card, but before he could hand it over, he paused, looking at Ethan with a patronizing grin. "Tell you what, Ethan. I’ll let you pay the bill. Consider it your final exit f*e. Oh, wait—I forgot. Your bank account probably doesn't even have three digits, does it?"

Chloe let out a soft snort, looking away in embarrassment.

Ethan felt the blood rush to his ears. The absolute humiliation suffocated him. He pulled his hand out of his pocket, leaving the cheap ring behind, and reached for his worn wallet. He knew exactly what was in his account: $3,250. His entire life savings, meant for the security deposit on a new place.

If he swiped it, he would be left with exactly fifty dollars to survive the month.

Ding!

Suddenly, a sound echoed directly inside Ethan's brain. It wasn't a phone notification. It was a crisp, electronic chime that made his vision blur.

[System Initialization Successful...]

[Binding Host: Ethan Wright.]

[Congratulations! You have unlocked the 'Absolute Cashback Multiplier System'.]

[Current System Level: 1]

[System Rule: Any money spent by the Host on external transactions will trigger an immediate multiplier rebate. Current Level 1 Multiplier: 100x!]

[Notice: Rebate funds are fully legal, laundered through global offshore tech investments, and completely untraceable.]

Ethan froze. A glowing, semi-transparent blue screen floated right in front of his eyes. Neither Chloe nor Oliver seemed to notice it.

A system? A golden finger?

"What's the matter, Ethan?" Oliver sneered, pulling his black card back. "Sweating over three grand? If you can't afford it, just say the word 'Master' and I’ll take care of it."

Ethan ignored him. His heart hammered against his ribs as he looked at the floating screen, then down at his own standard debit card. Was it real? Or had the stress finally made him lose his mind?

There was only one way to find out.

"I’ll pay," Ethan said loudly.

He took his card and placed it firmly into the waiter’s reader.

Oliver laughed out loud. "Trashing your entire savings just to save face? Pathetic."

Transaction Processing... Approved.

The machine spat out the receipt. The waiter bowed respectfully. "Thank you, sir. Payment was successful."

Ethan closed his eyes, waiting for the devastating text message from his bank showing his balance hovering at zero.

Buzz.

His phone vibrated in his palm. He looked down at the screen.

‘Capital One Alert: Your account ending in 4021 has received a direct deposit wire transfer of $320,000.00. Current Balance: $320,050.00.’

Ethan’s breath hitched. Three hundred and twenty thousand dollars. It was real. The 100x multiplier had converted a $3,200 dinner bill into a massive fortune in a single second.

[System Notification: Level 1 Daily Spending Limit: $10,000. Remaining limit for today: $6,800. Upgrade to Level 2 requires total expenditures of $50,000.]

Ethan stood up from his chair. The crushing weight that had been sitting on his chest for the last two years instantly vanished. He looked at Chloe, noticing for the first time how hollow and superficial her expressions were. Then he looked at Oliver, whose smug smile was still plastered across his face.

"Thanks for the dinner recommendation, Oliver," Ethan said, his voice entirely calm, devoid of the previous anger. "The food was mediocre, but the returns were excellent."

"Are you acting insane because you're broke now?" Oliver scoffed.

Ethan didn't bother replying. He turned on his heel and walked out of the private room. He needed to spend the remaining $6,800 before midnight to maximize his daily system rewards. His ascension had just begun, and these people were already beneath his notice.

Ethan walked down the neon-lit streets of the luxury commercial district. Every high-end boutique he passed—Gucci, Rolex, Louis Vuitton—used to look like forbidden territory. Now, they just looked like targets.

He needed to verify the rules of the system. Does the cashback apply to absolutely anything, or are there hidden restrictions?

He stepped into a premium electronics store. The sales representative looked at Ethan’s slightly worn suit and didn't bother getting up from his stool. "Welcome. Laptops are on the left, budget tablets are on the right."

Ethan ignored the dismissive tone. He walked straight to the center display case, pointing at a custom, liquid-cooled gaming laptop with top-tier specifications. It was a beast designed for rendering and heavy processing, priced at exactly $4,500.

"I’ll take this one," Ethan said smoothly. "And add that premium smartwatch over there for $800, and those noise-canceling headphones for $500. Wrap them up."

The salesman blinked, his attitude shifting instantly. He scrambled off his stool, his face twisting into a customer-service grin. "Right away, sir! Let me get those brand new ones from the back for you."

Five minutes later, Ethan handed over his debit card.

Transaction Approved.

Buzz.

‘Capital One Alert: Your account ending in 4021 has received a direct wire transfer of $580,000.00. Current Balance: $894,250.00.’

Ethan let out a silent breath. Total spent: $5,800. Total gained from the 100x multiplier: $580,000.

The blue system panel flashed again in his vision.

[Daily Spending Limit Remaining: $1,000. Current Level 2 Progress: $9,000 / $50,000.]

Ethan walked out of the store carrying three heavy luxury shopping bags. He had gone from worrying about his bank account hitting zero to holding nearly a million dollars in liquid cash, all within the span of a single hour.

He looked back toward the direction of the restaurant where Chloe and Oliver were probably still drinking their vintage wine. They thought they had broken him. They had no idea they had just unleashed a monster.
