I Stumbled Into the Imperial Household. Why Is This a Card World?

[Cards + Urban Setting + High Martial Arts + System + Wish-Fulfillment + Business]

Lin Jiahao was so handsome that his supervisor grew jealous of him.

He graduated only to find himself unemployed. After failing his probation period, he had no choice but to start researching OPC entrepreneurship.

He downloaded the recently popular AI software, ready to make his grand plans a reality.

"Veggie Bun Assistant, can I become an immortal and fly into the sky?"

"Of course you can!"

The next second, the world changed completely!

He was reborn at eighteen, at the high school college-entrance-exam oath-taking ceremony?!

What? A Veggie Bun AI Assistant had also been bound to his mind from the start?!

"I, Lin Jiahao, have returned as a king!"

Teachers and students across the school turned around and stared strangely at Lin Jiahao, a useless weakling with a combat rating of five.

Wait, this was a high-martial-arts card world?!

Other people's golden fingers could defy fate and change their lives!

Why was my Veggie Bun teaching me to set up a barbecue stall in a card world, sell milk tea, exploit information gaps, start a short-video business, and invest in stocks?!

This is crazy! Could there possibly be a more outrageous rebirth story?!
