An Ling'er, a modern returnee from overseas, fell into the abyss due to the humiliation of her husband's family before her marriage even started. An unexpected trip completely threw her away from the modern trajectory - she actually traveled through time and became the second young lady of the Prince's Young Master's Mansion who had just been ransacked and exiled! Skyfall starts, hell mode. From being the daughter of an official to becoming a Jiaofangsi, to being adopted as an adopted daughter by a powerful eunuch, she became a chess piece in the darkness of the palace... Every step was like walking on thin ice. When the substitute princess marries a Turk far away, what awaits her is not stability, but the power storm of the grassland and the fiery eyes of the rebellious second prince. She was exhausted physically and mentally from dealing with the affectionate prince of the current dynasty and the wild and unruly prince of the enemy country. What's even more fatal is that the eunuch's adopted son who grew up struggling in the darkness with her, his deep love for her who was willing to go to hell for her at the cost of self-mutilation, became the deepest thorn and the most painful warmth in her heart. In the troubled times, she stirred up the situation with her wisdom and helped the prince ascend to the throne. However, she also personally buried the life of the second Turkic prince and witnessed the eunuch who loved her deeply go to the execution ground under the pressure of power. When everything was settled, the huge sadness tore apart time and space and brought her back to modern times. With her body covered in scars and her heart turned into ashes, is this time-traveling a redemption, or is it fate's cruelest joke to her? Is what she took away the power of strategy and wisdom that could subvert everything, or the grief that will never heal in her lifetime?
