My clan brother framed me for stealing cattle, the clan leader wanted to drown me in a pond, and the whole village was waiting to share my property. When I opened my eyes, I, Ji Rang, traveled back in time to the third year of Zhenguan in the Tang Dynasty and became a poor orphan waiting to die. But no one knows that I have an atavistic system in my mind. Did you still eat raw rice with wild vegetables during the Zhenguan Dynasty? The yield of wheat per mu is less than eighty pounds? I planted three-crop rice backhand, used pesticides and fertilizers to increase the yield, and ripened it in three days, making the mountains golden. The cannon fodder laughed at my wishful thinking, and the village chief said that I went to the fields to waste good seeds—until the golden ears of rice hung down on their faces and the grains returned to the warehouse. Later, the imperial envoy from Chang'an City saw with his own eyes the heavy purple fairy potatoes in my field. Without saying a word, he rode his horse straight to Tai Chi Palace overnight. Emperor Zhenguan took the first bite and was stunned: "What I am eating is... Elixir?" No, it is high-yielding food that everyone can grow.
