History: I Transmigrate to the Ming Dynasty with a Delivery Station from the Start

Chen An transmigrates to the tenth year of the Hongwu era and gets a delivery station from the start.

He has to change history and make up for its regrets before he can get money to place delivery orders.

Unable to place any orders, Chen An is worried sick.

But just then, he agrees to marry a young woman and somehow gets the startup funds!

I have no idea... I didn't even do anything!

How did the Ming Dynasty end up changing...?
