She rescued the young master in trouble, but in exchange she "repaid her favor by taking a concubine". Yunya took the money and left, then turned around and bought a silent and capable "husband" Ajiang with twenty taels. She thought her life would be stable from then on, until an assassin came to her door, and she realized that the person next to her was actually a general who was deeply involved in a secret war in the court. This time, she no longer clings to anyone - she studies medicine, does good deeds, builds a career, and earns her own world with her own hands. And those who have abandoned her like worn-out shoes can only regret their lives in their memories.
