Michael slept much longer than usual so when he woke up he felt energized and ready to rumble.
However, rather than rushing outside, Michael ended up retrieving the books he purchased the day before. He released Extraction and started to extract the Wisps of Knowledge within the books.
The content and knowledge of the books were extracted one by one, slowly but steadily. He was being careful not to tear off the pages which meant that he spent the next four days in the Origin Expanse to extract countless Wisps of Knowledge, which he devoured immediately.
