The Beginning of the Thousand-Year Blood War

For Black Ant, these three years had passed in peace. He had remained in the Great Spirit Library, reading books, only occasionally coming out for some fresh air. The only notable events of those three years were that Aizen abducted Orihime Inoue in Hueco Mundo, after which Ichigo Kurosaki entered Hueco Mundo to rescue her and was beaten badly. After returning to Soul Society and undergoing training from the various captains, he finally knelt before Black Ant and begged him to train him.
