Colosseum

Michael left the Origin Expanse a few days later with his physique fully restored.

After returning to the Saphirelake Military Academy, Michael first walked over to the Bartholomew Shop where he handed his shopping list to the staff. He then entered the appraisal room with another attendant while the staff began to get the goods written in the list.

'I hope they find everything,' He thought while retrieving all Artifacts that had been starting to collect dust in his War Rune's storage space. 

Following the Artifacts, Michael also retrieved the blueprints he didn't need since they were duplicates.

"I hope you can give me a good price for everything," Michael said to the attendant, whose eyes widened in surprise.

The attendant took a while to regain his senses. He then called the shop manager to proceed with the purchase of the Artifacts and blueprints since he was not authorized to make such a big deal on his own.
