A concubine who doesn't want to be a queen is not a good concubine.
They have family backgrounds, are favored, and dominate the harem. But all of them had a bad fate.
Chen Niannian takes the system with him, travels through different time and space, becomes them, and changes his miserable fate.
The first world: Concubine Tong vs. Kangxi (I am the closest person to the emperor's cousin. I want to be the queen who will accompany him until he grows old, not the queen for a day.)
The second world: Nian Guifei vs Yongzheng (My three sons and one daughter all failed to grow up, I want to protect them.)
The third world: Concubine Gao vs Qianlong (I will live longer than a big pig's hooves.)
The fourth world: Linzhi Palace Royal Concubine vs Huang Taiji (not Bai Yueguang, but the last laugh)
…
The heroine has a vicious character, and she won't come clean.
Intention: Cherish the present
