Spring Tide of Swapped Brides

In her previous life, Luo Fu married Commander Pei Ji. Her legitimate elder sister, Luo Zhen, entered the palace and painstakingly rose to the rank of concubine. However, Emperor Murong Jin was a crazy tyrant, cruel and bloodthirsty. Luo Zhen's position as concubine wasn't even warm before she perished at the tyrant's hands. Meanwhile, Commander Pei Ji steadily climbed to a high position, eventually seizing the opportunity to rebel and ascend to the throne. Luo Fu, too, naturally became the Empress.

In this life, Luo Zhen, who had gained foresight, snatched Pei Ji for herself. Luo Fu was sent into the palace instead. Luo Zhen waited for her illegitimate younger sister to die a premature and tragic death, and for Pei Ji to ascend the throne, so she could enjoy the position of Empress herself. But she waited and waited... "Why hasn't Pei Ji rebelled yet?!" "Why does Pei Ji love Luo Fu even more than in the previous life?!" "Why isn't the crazy tyrant killing people anymore?!" "Why has the crazy tyrant disbanded his harem?!" "Why has Luo Fu become Empress again?!"

P.S.: The female lead is a "salted fish" (lazy but lucky), unparalleled in beauty. No matter what circumstances she is in, she will first ensure her own comfort. Both the male lead and other male characters only love the female lead. Only with her by his side could Commander Pei Ji become emperor. Only with her by his side could the tyrant Murong Jin return to normal and prevent the collapse of the imperial court. She is destined to be an empress; no matter how the marriages are exchanged, she will always be the empress. This is a sweet and satisfying novel.
