Her name was Shen Zhaoning, the eldest princess of Chen State. She went to the battlefield at the age of sixteen and died in front of Xuande Gate at the age of twenty-two.
The moment before she died, she watched Li Huaijin, the North King of Daliang Town, kill her most trusted subordinate Yang Shu, and saw the poisoned arrow shot from behind - she grabbed Li Huaijin and asked him to block the arrow for her. She thought this was her last revenge before she died.
But what she didn't know was that Yang Shu had been an undercover agent placed by Li Huaijin beside her from the beginning, and his mission was to protect her; Li Huaijin killed Yang Shu in order to prevent her from knowing the truth of being deceived for ten years; Li Huaijin took the initiative to block the poisonous arrow for her, and he was fully capable of avoiding it; and those strangers who fought to cut off her rear and fell in front of her one by one on her way south were all personal soldiers arranged by Li Huaijin in advance.
She didn't even know that Li Huaijin had loved her since the first time he saw her on the battlefield six years ago. He hid this love for two lifetimes and never said it out loud.
She was reborn at the age of seventeen with full of hatred, and vowed to kill Li Huaijin with her own hands in this life and avenge all the people who died in her previous life. And Li Huaijin was also reborn with memories - he knew she hated him, but he didn't explain anything. In his opinion, loving her is his own business and has nothing to do with her.
Until she stabbed the sword into his chest with her own hands. The last words he said before he collapsed were "Just stay alive." Until she found a portrait in his study - the painting was of her standing in front of Xuande Gate in her previous life. There is only one line of words on the back of the portrait:
"From the first moment to the last moment."
Only then did she realize that she was not killing her enemy, but the only person in the world who had protected her with his life for two lifetimes.
