Memories from that time were a blur for Rex as he sought to get rid of it.
It was one of the most painful times that he had experienced aside from the death of his parents. He wanted to get it out of his head lest he went insane, however, he could recall that his preparation took a long time to finish.
He needs to reach an appropriate strength first before he can attempt to save her.
Save Rosie.
Despite the help from the System, the preparation took longer than expected.
When he reached there, it was already too late.
Rosie has already been sacrificed, her blood and soul were used to forge the Blood Devourer.
All of the pain flooded back to him when Nezera brought up the Blood Devourer, forcing him to remember that time again which was why he was in a very bad mood. He didn't remember whether Calidora had already told him about this truth or not.
But it feels like this was the first time she told him about the truth.
