I Started with a Broken Picture, and I Hollowed Out the Luck of the Dynasty.

Just after time travel, he was devoured by his relatives and became the laughing stock of the whole city? It's okay, my treasure map is automatically refreshed every week! While others are practicing martial arts, I mine mines, while others are fighting for my "infrastructure". While they were still fighting for one or two martial arts secret books, I had already figured out cement, gunpowder and magical skills with the resources I dug up! When I dug out the dynasty's dragon veins with a shovel, people all over the world were shocked to realize that the most useful "gold finger" was to be a shady "resource guy"!
