In the ninth year of Chongzhen, during the famine years when people died of hunger everywhere, young Shen Du took a mysterious pill and became immortal.
He didn't know that the price of immortality was that every hundred years, the person he loved most would die on his behalf.
Three hundred years later, the system arrived and the truth was revealed.
He forgot her three times and she waited for him for three hundred years.
When the memory is revived, immortality is no longer a gift, but the cruelest curse.
