Deng Ai was not discouraged when his official career fell from the clouds to the bottom of the valley. Not only did he study the growth of farming every day at work, but Deng Ai, who embraced the dream of being a general, would survey and measure the terrain every time he went to the mountain, planning where to march and where to camp. Everyone treats Deng Ai as a sad joke, ah, how come you are so powerful and still mow the grass? But Deng Ai didn't care about ridicule and insisted on doing what he liked. After more than ten years of mowing the grass, one day, Deng Ai went to Beijing to report.
Although he was still ridiculed for his poor expressiveness, Sima Yi, the chief officer, objectively believed that Deng Ai was a genius of hard work. He photo retouching not only recruited Deng Ai to cultivate in his own house, but also promoted Deng Ai as Shang Shulang, the current administrative secretary, and became a key official of the country. For 240 years, Deng Ai supervised local agriculture. Deng Ai wrote the "Jihe Lun" with many years of research experience in farming and used it.
It really brought a bumper harvest in the local area. At this moment, Deng Ai seems to be the national agricultural authority, but Deng Ai is still determined to be in the field. At that time, the imperial court was divided into Sima Yi faction and Cao Shuang faction. Since Sima Yi faction was always suppressed by Cao Shuang faction, Deng Ai, who belonged to Sima Yi faction, had absolutely no possibility of leading troops to fight.
