A Song of Ice and Fire: Kingdom Rush

With all due respect, for the sake of the family, something like a holy marriage is completely necessary. Only in this way can bloodline be purified as quickly as possible. I don't know what Unfilial Descendants are looking for, a person with three top talents, because he was given a fiefdom after his nephew's education and didn't care much about it. Later, when he wanted to be the heir, he found that all his children were crooked. The main spouse also had an ugly trait, and the other three secondary ones had no traits at all. It was such a waste. (It is also best not to enshrine family members arbitrarily, otherwise not only will everyone forcefully declare the succession, but if they refuse to accept the tyranny, they will rebel collectively. One person has to suppress the entire family. Although he can win, it is really tiring for one emperor to conquer half the empire.)
