Ming Dynasty: My Sister Queen Ma

I am Ma Zegan, a time traveler, a person who should not exist in this time and space. My father died young and I became an orphan. I was picked up by an old Taoist and brought back to the mountains. I learned marksmanship to save my life and medical skills to save others. I thought that this life would be my fate as a wild doctor, until my master gave me a family heirloom jade pendant and a blood letter before he died—— Overnight, I gained many noble identities. Empress Ma was my biological sister, the founding emperor of the Ming Dynasty became my brother-in-law, Prince Zhu Biao wanted to call me uncle, Chang Yuchun patted me on the shoulder and called me brother, and Xu Da accepted me as his disciple. But none of them know that I have history six hundred years from now in my mind. I knew that the prince would die young, that Chang Yuchun would die suddenly, and that the entire empire would be turned upside down in a disaster. But now, because of each of my rescue efforts and every "unintentional" advice, history is deflecting crazily, and Ming Dynasty is heading towards a completely different future.
