Emperor Minghua was still young. On the surface, he had four children, three princes, and a princess.
Among them, the princess was born by the Empress. Even if everyone knew that she was not a real princess, because she was only an innocuous princess, no one wanted to expose her.
The Eldest Prince, Second Prince, and Third Prince were all born of the concubines in the harem. Their ages were not much different, and they were all 16 or 17 years old.
When Emperor Minghua sat on his throne, a strategist said that Emperor Minghua had to produce some descendants early as he had no children and was disliked by the previous Emperor.
At that time, Emperor Minghua had yet to take in a concubine. He only had one concubine given by the previous Emperor, and his Empress Qin.
Empress Qin was still young, and Emperor Minghua couldn't bear to see her give birth too early, so he kept delaying.
