What Should I Do If the Reborn Girl Is so Successful in Disguising Herself as a Man?

In her previous life, her name was Lan Xi. She was an extraordinary saint born in an overseas fairyland. She spent her life refining exotic fragrance. In this life, her name is Shen Xianyue, and she is the eldest son of the prime minister of Daheng Kingdom. A woman disguised herself as a man for twenty years to help the prince ascend the throne, in exchange for the freedom to travel around the world. She had already let go of her past life, but during her travels, she slowly unveiled the veil of the overseas fairy mountains. It turned out that there were so many little-known secrets in the overseas fairy mountains that she didn't know about. Living swordsmanship, mysterious alchemy, the art of controlling people with strange fragrances, the secret map of the stunning divine phoenix, immortality... In her last life, she lived alone on an isolated island and never saw any fireworks. This time she had to live her life over again, and she would live happily with the people she cared about most, do the things she wanted to do the most, live the life she wanted to live the most, and see the world she wanted to see the most.
