My Husband Has a Pure Heart and Few Desires, but I Gave Birth to Three Children in a Row

I was forced to get married in my previous life, but on the wedding night, the man said that he was an eunuch and could not be humane. Given two choices, one is to remain a widow, and the other is to set me free. In my previous life, I packed up my things and ran away overnight, but was murdered for my money and died in a foreign country. As someone who has traveled through time in this life, I know that the eunuch man in front of me will be a high-ranking official in the future who will be respected by everyone. Marrying him only requires a few years of hard work, and then you can become an official's wife. You don't have to worry about having children or concubines. It's perfect. So when the man asked, he chose one without even thinking about it, being a widow. It's just that although I haven't eaten much of this suffering, isn't it the result of heaven's castration? But why are there so many more babies? Also, this man clings to me every day. When can I become the first-grade wife?
