Once Solare finished fusing with the God Seat, even though his cultivation wouldn't reach the God Realm, he would still become a powerhouse. It was only a matter of time before he became a God and spread his Law throughout the Four Realms, further strengthening its foundation.
So, the importance of Solare to the God Realm itself was high now. With that, he was the perfect target for the Abolition Tower. Once he was killed while in the process of fusing with the God Seat, not only would he die, but it would also cause the God Seat to be destroyed.
Krune didn't know the reason why his clone was targeted in the infant supercontinent before. However, he was aware that either his clone or the couple it accompanied there had chanced upon something important.
