At that time, the original owner was pregnant, but her gestational age was tampered with. She was framed by the regent for murdering the emperor's heir, and was about to die.
After waking up, Su Ruoli was accidentally bound to the "historical database system". With the help of modern forensic knowledge and system, she first exposed the conspiracy through accurate gestational age identification, cleared some of the grievances, and rescued her life from the gate of hell. In the desperate situation of the cold palace, she not only had to deal with the harem's overt and covert attacks and the regent's constant pressure, but also had to protect her unborn child. She gradually discovered that behind the original owner's experience was a power game that affected the foundation of the court.
She uses a forensic perspective to unravel a series of palace mysteries - from the suspicion of arsenic poisoning in the imperial kitchen to the prevention and control of plague in epidemic areas. She uses modern medical knowledge to improve the imperial hospital system and uses criminal investigation thinking to crack political traps. At the same time, she cultivates confidants and unites available forces to gain a foothold in the turbulent court. When the emperor was controlled by poison and the regent's rebellious intentions were revealed, she was no longer limited to self-protection, but took over power step by step: promoting women's scientific research, reforming the economy, stabilizing the frontiers, and finally ended the chaos with thunderous means, ascended to the top of power, and became the first female emperor of the Dajing Dynasty.
