Dressed as a Female Assassin, I Struggle to Survive

[No system + no cheats + time travel + food + farming + making a fortune + power and business wars, etc.] Xin Youran finally took advantage of the opportunity of her graduation trip to go to the mountains to search for wild herbs, but accidentally slipped on her feet and fell off the cliff. When I woke up, I found that I had traveled to the Great Liang Kingdom, a dynasty that had no history at all, and that I was in the body of a top female assassin, Xue Ying. Prince Mu Yuan of the Daliang Kingdom received information that the female assassin Xue Ying, who had never failed, took over the task of assassinating him with a bounty of ten thousand gold. This news made him inexplicably excited, so he took the initiative to join the game. The mantis stalked the cicada and the oriole followed, but the assassin Xue Ying was stabbed in the back. Prince Mu Yuan was intoxicated by the incense, tied together, put into a sack and thrown off the cliff... After being rescued, Xin Youran came through. What's even more outrageous is that the two were mistaken for infatuated lovers who eloped and died in love. Prince Mu Yuan: He fell off a cliff and was seriously injured. He couldn't beat this female assassin, so he might as well pretend to have amnesia so that he could see the monsters clearly after death. Xin Youran: How does it feel to wake up and be in the same room as the original assassin? Don't ask, asking is just trying to escape! What? Amnesia? It seems that her life is not deserved! Then you might as well take advantage of the situation, try your best to pretend to be a loving couple in front of others, and start a new chapter in your life. Kill? I couldn't kill a few people, I wanted to survive hard, but I didn't expect to escape all the way and actually develop a new track, plant flower fields, build a brand, lead the villagers to make a fortune, and finally become the crown prince by accident?
