No system
In his former life, he was just an unemployed vagabond. He ate and slept in a daze. When he woke up, he traveled through time to a farmer's house, dreaming of doing something great and leaving his name in the history books! Unexpectedly, I learned from the memory of the original owner that it was the third year of Hongwu in the Ming Dynasty. I was really impressed. I had never done anything bad (i. E., I cheated the children with lollipops and deflated the tires of the property). How could I have traveled to the place of Zhu Yuanzhang, the great emperor of Hongwu! Even if I travel to the end of the Ming Dynasty, I can live safely. If I travel to the Song Dynasty and rebel, I am very sure. If not, the Qing Dynasty will resist the banner of resisting the Qing Dynasty and restoring the Ming Dynasty. But it happens to be the Hongwu period, and the four major cases have not yet begun. It is quite powerful to be able to live for three days as a official ("Kongyin Case", "Hu Weiyong Case", "Guo Huan", "Lanyu Case")!
It is better to farm the land honestly first, and then wait for Emperor Hongwu to drive Hexian before considering other things.
