I Built Farming Infrastructure for Qin Shihuang

His Majesty the First Emperor learned from his servants that his daughter had been behaving strangely recently, so he went to check on her. When I arrived at my daughter's palace, I saw her digging the soil and asked her what she was doing. "Grow potatoes," he replied, and gave the First Emperor a plate of hot and sour shredded potatoes. A few days later, the First Emperor couldn't forget the spicy and sour potato shreds, so he went to see his daughter again. He saw her digging the soil again, and asked her what she was doing. "Grow sweet potatoes," he replied, and made a dish of shredded sweet potatoes for the First Emperor. The third time I saw my daughter planting corn. The fourth time I visited my daughter and shelled the wheat. The guards around the First Emperor were shocked: "Your Highness, wheat is the food of the untouchables. You..." Qin An waved his hand: "You don't understand." When the wheat was shelled, ground into powder, and made into various delicious pastas, His Majesty the First Emperor was full. Guard: "The princess is truly a divine person." After the first interstellar ancient Chinese farming infrastructure game was launched, it became popular throughout the universe. Qin An also started playing this game, and her identity was the daughter of the First Emperor. Qin An engaged in agriculture and infrastructure construction, and also cured the health of the First Emperor who was damaged by taking the "elixir". Feeling that the game was almost over, Qin An was ready to quit. Then, Qin An discovered to his horror that the escape button was missing! Finally, Qin An understood the situation: "What? I'm not playing a game, I've traveled through time?" Purpose: I hope everyone in the world will be well fed and clothed
