The current situation is definitely the responsibility of Emperor Zhao Rui, but the real reason is that the Crown Prince could not produce an heir.
If the Crown Prince had borne him a grandson early on, he wouldn't have to do this. What he is doing now is also for the continuation of the Zhao family's Da Li Dynasty.
Of course, his vision is somewhat limited.
In fact, it is entirely possible to select a child from the royal offspring to be adopted by the Crown Prince, and the problem would be solved.
But no one can get over that psychological barrier. Having lost the throne struggle, how could one let descendants return to the supreme position in such a way?
Would the person sitting on the throne be content?
Moreover, when this child comes to power, will he establish his biological parents' line as the legitimate lineage?
And one's own line might thus become extinct, even if one does not choose a candidate with previous enmity against their faction for adoption.
