[A scheming, chronically ill prince from ancient times + an emergency room doctor whose soul travels to the past + a link between ancient and modern times + a best friend who sends supplies + modern goods sold in the past + getting rich + dealing with awful people]
Su Liuxin travels to ancient times and discovers that her medical kit is extraordinary: it connects the past and present, letting her trade supplies with her best friend, Liang You.
Together, she and her best friend make a fortune and deal with the awful people around them.
The prince's manor is run by the side consort, who refuses to give her food or drink?
No problem. Her best friend sends supplies, so she gets to eat and drink well, and even wins the prince's heart along the way.
Her entire birth family is thrown in prison and falsely accused of forming a faction for personal gain?
Don't panic. She has all kinds of amazing modern gadgets. A voice recorder exposes the mastermind who framed the Su family, and the evidence is irrefutable!
Her husband is poisoned and on the brink of death?
No worries. A top modern medical team will research an antidote for the prince.
Someone frames their prince for treason?
Hold on, where's the evidence of his rebellion? Why has it disappeared?
Someone is hunting the prince?
The prince has actually run off to the modern world.
What? Li Jingyao, you don't want to go back to ancient times?
Oops, it ended neatly, and the writing was good, but it was too short. Earlier, I said that the emperor and the princess went to play on behalf of others, but in fact they didn't go in the end.
The original person is dead, and the heroine still shamelessly stays with the scumbag?
