The Grace of Saving Life Should Be Faced with Swords

[Pretending to be a pig and eating a tiger × reversal × replacement × black cut × slightly funny] Lan Nian just went out and returned home. Her family was gone, her father was dead, and her sister was almost out of breath. To get revenge, she took on the path of taking on her sister's identity, went all the way to the capital to recognize her relatives, and then pretended to be a pig to eat the tiger. After killing the culprit who framed her sister, Lan Nian discovered that things were not that simple. Behind one life was another life. She was forced to walk to a more dangerous cliff, and she did not hesitate to put herself in danger. Of course, one life must be exchanged for another, no loss. So she planned and worked hard just to drag them down one by one. Lan Nian had no conscience and used all the resources around her equally. Then she suddenly remembered the 'life-saving grace' that she had forgotten for a long time. Lan Nian felt that she was not a good person, at least not a kind person, and they said not to pick up men on the roadside casually. She always felt that this sentence was very reasonable and believed it deeply, so she was not saved, but it did not prevent her from using kindness to win over the prince. So after figuring out the pros and cons, Lan Nian turned around and asked him with a smile, "Prince Xie, do you still need a concubine?" Xie Zhiyu:? What tricks is she up to? (Perhaps it is a story about a medical woman who gradually became a county boss and then became a staff member for revenge? Although the process was a little deviated, it did not affect the final result at all. Lan Nian was quite satisfied.) (I don't know how to write an introduction, so please move to the main text.)
