This is a fictional story set in an alternate history, not real history.
In her previous life, Jing Rui was a top all-around talent in the modern world. She founded the mysterious Dark Night Pavilion, an organization filled with experts in intelligence, assassination, and hired work. During a mission, she died unexpectedly while trying to save a dear friend. When she awoke, she found she had been reborn in the Qing dynasty, born anew into the world.
On the day she was born, rosy light filled the palace and heavenly omens appeared. From then on, she was doted on by Emperor Yongzheng, who personally raised and educated her for over a decade. He once lamented that if she had been born a man, she would have been capable of ruling the Qing Empire.
Before his death, Yongzheng entrusted her with the entire network of the Imperial Bodyguard Bureau, the Blood-Drop assassins, and several blank imperial edicts. With these unbeatable trump cards in her hands, she had planned to lie low in the palace and hoped that one day she could leave and live out a quiet life. But one late night in the first year of the Qianlong reign, she fell for the young, lowly eunuch Jinzong at first sight in the Imperial Kitchen.
Everyone envied Jinzong for winning the Grand Princess’s favor, but no one knew he carried a past steeped in blood.
In his previous life, he had given his loyalty to the wrong people and met a gruesome end. Reborn, he entered the palace under another identity, swearing to put his foolish longing behind him and plan every step, all for revenge and a peaceful life afterward.
But for all his calculations, he still lost to love at first sight.
On the night they first met, the radiant Grand Princess burst unexpectedly into his frozen heart, becoming the only light in the darkness of his life, the one person he kept hidden in his heart and dared not presume to approach.
Within the red walls of the imperial palace, they cautiously tested each other and drew closer by degrees. As the court fell into turmoil, they stood side by side, protecting each other through life and death.
In the end, Jing Rui used her iron-fisted methods to break through the shackles of convention and status, ascend to the supreme throne, and stand with Jinzong, whose devotion remained hidden deep within him
There's nothing wrong with the heroine, she has no sense of existence
The heroine's sense of presence is too low and she is too frustrated. It is completely impossible to tell that the heroine is a heroine.
