I Own a Supermarket Between Two Worlds, and Every Dynasty Works for Me

Dynasties clash across the ages, while I sell canned food atop the city wall.

Transmigrating into the unlucky heir caught between the three great empires of Qin, Han, and Ming, Ying Ping'an is facing the fall of his country from the start.

At the end of his rope, the [Supermarket Between Two Worlds] opens up:

A case of compressed biscuits for one yuan, a stab-proof vest for ten yuan, and buy ten compound bows, get one free.

While everyone else burns through provisions to wage war, he burns through braised pork.

When Ying Zheng sends troops to lay siege to the city, Ying Ping'an sets up dozens of giant pots on the wall, and the smell of meat fills the battlefield.

Qin Vanguard: General, the enemy troops... are eating better than we are.

Wei Liao: ...Retreat.

From the city management brigade to an unstoppable force of steel, from surviving between the cracks to winning the submission of every dynasty.

Ying Ping'an says, “What emperors of the ages? They’re all destined to work for me.”
