Dragon, Phoenix, and Pig Theme Park

Bai Yao inherited an amusement park that was on the verge of closing. As the owner of a part-time job System, he quickly activated the sky screen function, connecting it to every dynasty throughout history. "On opening day, choose one time period for free as a trial venue. Qin, you're up." The First Emperor: "..." What nonsense. Do you think I would pay you any attention? Everyone else: Hilarious! The First Emperor's been picked to work! Bai Yao waved his hand. Please watch this video. "Want crops that yield a thousand jin per mu?"--Golden fields of wheat, swaying in the breeze "Want to fly?"--An airplane soaring into the heavens "Want to know the future?"--The long history of China, all written in the history books "Want..." "I want it!" The First Emperor readily agreed to set up a stall. "I want it all!" Bai Yao: "Deal. Choose a place to set up the exhibit and decide who will take part as soon as possible." Everyone else: "We want it too!" Bai Yao: "Everyone else has to pay." Everyone else: "..." They were so jealous their eyes were practically turning green! The amusement park became a theme park, and soon a huge wave of visitors arrived. Bai Yao set aside a plot of farmland for Qin and planted a sign beside it: "Field to Ease the First Emperor's Burden (Seedlings sold separately. Outstanding workers may take a photo with the First Emperor.)" The First Emperor was worried. Would this really work? Within half a day, every seedling had been planted. A huge hit! Three days later, the seedlings had matured. Bai Yao replaced the sign with another: "Field to Ease the First Emperor's Burden (Rent sickles next door. No sneaking them home. Outstanding workers may take a photo with the First Emperor.)" The First Emperor was still worried. Would this really work? Within half a day, all the wheat had been harvested and stored. A huge hit! The First Emperor: "..." Bai Yao: Make money three times over from one theme park. What a windfall! Note: 1. All historical periods are parallel timelines, so nothing anyone does will have any effect on actual history. Theme: People have two great treasures, their hands and their minds. Work hard for a better future
