The Ancestors of Every Dynasty Take Jobs to Strengthen the Nation [Ancient Times to the Modern Era]

Sheng Fang was tens of millions in debt when she bought a rundown tourist attraction. The System told her she could hire the ancestors to work for her! High-yield crop seeds! Solar panels that could generate electricity! Compact drones! As long as you work and earn money, you can buy them all! Qin Shi Huang, Li Shimin, and Zhu Yuanzhang: Buy, buy, buy! The ancestors discovered that not only could they earn money working here, they could also gossip about what happened in later dynasties! Zhao Kuangyin: What? His younger brother is the Chariot God of Gaoliang River? Zhu Yuanzhang: Who's the God of War of the Ming dynasty?! Li Shimin: You little brat, get over here! Tell me, who's your wife?! Note: Alternate history, not historically rigorous. Many dynasties from parallel worlds will appear. The male lead shows up much later, and there's little romance. Theme: Gain wealth through hard work
