System in Hand: the Poison Doctor Princess Defies the World

The original owner "Shen Qingli" was an arrogant, domineering, jealous and brainless princess. Because she repeatedly framed the kind and tenacious time-traveling heroine (the real heroine of the original work, such as Lin Qingyue), she was eventually rejected by the cold prince Xiao Jue, thrown into the cold hospital, and died miserably. When Su Wan came back, it was the original owner who had attempted to poison the concubine/Bai Yueguang but was exposed. She had just been imprisoned in the most dilapidated cold hospital in the palace, was poisoned with chronic poison (perhaps due to her own misconfiguration or someone took advantage of her and was poisoned), was dying, and had the "start of hell" with everyone betrayed and separated from her relatives.
