After three years of Tianbao, the rain fell in Nangong.
She is a pawn manipulated by lies, an assassin with a blood feud who entered the palace to kill the king.
He is the banished immortal who sleeps drunkenly in Chang'an, writes poetry and swordsmanship, and is the guardian who sees through all her frailties at a glance.
She thought her enemy was the Nine-Five Master, but little did she know that the real murderer had been sneering behind the scenes.
He was used to seeing the ups and downs in the court, but he was moved by a noble concubine who couldn't help himself.
The deep palace is like a prison, full of poisons, and there are sharp blades hidden on the strings of the pipa.
Under the moon in Chang'an, a sword protects each other, and poetry and wine gently relieve the worries of the world.
"I'm not here to harm anyone, I'm just... So scared that I have nowhere to go."
"Don't be afraid. As long as I'm here, no one can force you anymore."
Intention: fake assassination, real redemption, sadistic destiny, running in both directions
