Su Yan, a master's student in infectious diseases, unexpectedly fell into another world after her defense. When she opened her eyes again, she turned out to be the legitimate daughter of the Su family who will marry into the East Palace in seven days.
Mother-in-law makes things difficult, concubines set up traps, relatives fight, a cup of tea or a box of medicine in the palace may become evidence of putting someone in danger. Su Yan does not have an omnipotent golden finger. She can only rely on medical common sense, evidence collection habits and a lake pen that travels with her to turn dead ends into lives again and again.
She lived in seclusion in the cold palace twice, but she did not wait for the prince to rescue her. But the man with whom she was wary of each other at first, later shielded her from the wind and rain, and also handed the mountains, rivers and sincerity into her hands.
From the Crown Princess to the Queen Mother, Su Yan has saved people and lost loved ones. She finally understood: If you want to keep the one you love, you can't be a pawn in the palace forever.
This time, she will play chess side by side with Xiao Heng and control the mountains and rivers together.
