My Supermarket Connects to All Worlds, and Emperors of Every Era Beg Me for Stock

[Historical what-if] [Two-way portal] [Righting past wrongs] [Infrastructure fanatic] [Emperor for the ages]

“If you had the chance, which regrets in Huaxia’s history would you change?”

Chu Yan’s bankrupt supermarket binds to the Myriad Realms Marketplace System. It can buy and sell goods for profit, and even connect to parallel historical worlds.

From the start, it connects to the Qin Empire. Faced with Qin Shi Huang, who is superstitious about alchemists and in failing health, Chu Yan not only cures the First Emperor with modern medicine, but also uses a photo of the Great Wall on his phone to reveal the grim future of the Qin dynasty’s downfall after only two generations.

“Your Majesty, the Great Wall will still stand two thousand years from now, but the Qin Empire will be gone. I’m here to help the Qin defy fate and change its destiny!”

And so...

In the Qin Empire, he teaches Fusu modern economics and supplies the Qin army with high-yield hybrid rice and improved repeating crossbows, enabling the Qin cavalry to truly conquer the world!

In the Han Empire, he provides Huo Qubing with unlimited antibiotics and supplies, saving the peerless general and helping him win glory at Mount Langjuxu!

In the Ming Empire, he gives Zheng He a modern map of the world and blueprints for a steam engine, letting the Ming fleet launch the Age of Exploration five centuries early!

In the Song Empire, he brings the most advanced steelmaking techniques and stands firm at Fengbo Pavilion, determined to keep Yue Fei from meeting the same fate!

Before he knows it, Chu Yan has become a “space-time peddler” who travels across the Myriad Realms. With modern technology and supplies, he has hammered out a grand alliance of Huaxia kingdoms powerful enough to overwhelm the Myriad Worlds!
