After the Marriage Failed, I Developed the Emperor into a Downline

The useless princess Shen Yu was thrown into the cold palace to die, but a mysterious organization called Tianyan League came to her door and asked her to poison the emperor. She was about to accept her fate when Jun Wuchen, the deposed prince next door who was about to die of illness, told her that you were being used and you would be the first person they killed after the incident. The two losers joined forces in the cold palace, fighting wits and courage with the Tianyan Alliance while investigating the real culprit who framed Jun Wuchen three years ago. In the end, she discovered that from the day she entered the cold palace, every step had been planned, and the real enemy was far closer than she thought.
