[Reborn as a substitute bride + palace and household intrigue + revenge + both leads are each other's first and only + two powerful leads]
In her previous life, before Jiang Jiting was sent to the enemy state as a hostage, her father promised her the position of Crown Princess.
So, for her father's peace of mind and the sake of peace between the two states, she pretended to be meek and obedient in the enemy country, humbling herself to the dust.
But after ten years, the father who had sworn he loved her discarded her once she was no longer useful, joining forces with the enemy crown prince to imprison and torture her until she died a miserable death in a foreign land.
When she opened her eyes again, she was on the road to the enemy state. Jiang Jiting killed her escorts, assumed a new identity, and swore that this time she would kill every faithless traitor who had betrayed her.
Thirteen years later, an imperial decree arranging her marriage arrived. Hiding her secret identities, she returned to Qingyun City and married a crippled, short-lived prince who had been poisoned.
Everyone pitied her, but Jiang Jiting thought that just as she'd been getting sleepy, someone had brought her a pillow. Once she used the short-lived crippled prince to kill that pack of beasts, his death would be the perfect time for her to take power and choose whichever handsome man she wanted...
But when Jiang Jiting sought revenge, the short-lived prince brought her enemies right to her feet. When she set out to seize the throne, he took it himself and handed her control of the army.
Jiang Jiting couldn't make sense of it. “Aren't you supposed to be short-lived? Why are you still alive?”
The man pulled her into his arms, his voice trembling. “Because I can't bear the thought of Ah Mu sharing a bed with another man~”
Jiang Jiting had had enough. She kicked the disheveled man aside, led her army in rebellion against Xueyue City, and became the first female emperor of the four kingdoms.
On the day of her coronation, Jiang Jiting was in the highest spirits, until she returned to her room that evening and saw the man on her bed, dressed like a courtesan. Her mood turned cloudy...
It's well written, and it's my favorite type. The only drawback is that it can't produce pictures.
