The Whole Family Transmigrates: You Call This an Ordinary Poor Family?

Zheng Zhi's entire family transmigrates to ancient times, landing in a poor household. While everyone else is still struggling to make ends meet, the family of four has already begun living a ridiculously overpowered life...

Dad: "It's just the imperial examinations. I'll take them casually and snag a top-three rank."

Mom: "The Empress Dowager has an incurable illness? Don't worry. Take the medicine I prescribe, and she'll live another thirty years."

Little sister: "Today, we're learning calculus. Feel free to interrupt me if anything is unclear..."

Zheng Zhi: "Your Majesty, the Great Sui has no rivals left on Blue Star. Our destination should be the stars and the sea!"

The Emperor: "Excellent. I hereby order you to set out at once and explore the universe!"
