The most angry were the eldest prince and Consort Hui.
The First Consort gave birth to four children, all of whom were girls. She desperately wanted to have a legitimate eldest grandson, but unfortunately, the Third Consort got the first one.
When the Crown Prince learned of this, although he was somewhat disappointed that his wife's belly was still not showing signs of pregnancy, he was happy as long as it didn't benefit the First Prince.
The Third Prince was overjoyed to have a legitimate son.
Because Yinzhen had brainwashed him, he would occasionally have lunch with the Third Prince's wife, which made him feel that this son was very much like him.

"What method?"
"Vaccination with smallpox vaccine."
"Cowpox?"
"It's also my fault; I never thought of this before."
"Tell me more about it."
