The Tang Dynasty's Most Dutiful Son: Old Man, Get in Line for Noodles

[Historical What-If + Two-Way Supermarket + Unruly Son Beyond Compare + Lighthearted, Wildly Satisfying + Decisive and Ruthless]

After transmigrating to the early years of Zhenguan, Li Fuyao becomes a prince bearing the imperial blood of both the Sui and Tang dynasties.

He awakens the [Filial Son Supermarket System]. The back courtyard of his prince's estate connects directly to a modern wholesale superstore from the year 2000, and he even has the peerless combat power of the real Lu Bu to back him up!

Li Fuyao sets the rules: modern industrial goods will crush the past with ease, every item has a clearly marked price, spoilers about the nation's fate cost extra, and Li Er pays double in the store!

"Old man, how about a set of artificial glass cups that cost thirty taels of silver, but can be resold to the Five Great Clans for three thousand?"

Li Shimin: "I'll take it! Put it on the imperial treasury's tab! And while you're at it, tell me how the Tang dynasty will fare..."

Li Fuyao rubs his fingers together. "That'll be one hundred thousand taels for a spoiler about the nation's fate. Also, old man, you cut the line. Go wait your turn!"

Li Shimin draws his sword in a fit of rage. "You rebellious brat! I'm your father!"

[Ding! Host has completed 'Publicly Humiliating the Old Man.' Judgment: Exemplary Filial Piety! Lu Bu's combat power +100. Reward: ten thousand cases of self-heating hot pot and a battalion of peerless heavy cavalry!]

Seeing Li Fuyao crush a black-iron sword in one hand, with eight hundred divine generals radiating killing intent behind him, Li Shimin faints on the spot and hastily plays dead. "Quick... carry me off to have a bowl of Old Jar Pickled Cabbage Beef Noodles to calm my nerves..."

The entire court rushes to invest, while the aristocratic clans are stripped bare.

Li Fuyao taps a gold bar and sneers:

"Old man, which will it be: Xuanwu Gate 2.0, or stepping down quietly and becoming Retired Emperor?"
