Rank 7 Refinery

Eva looked at Draco's side profile with stars in her eyes. 

This aura of wealth, debauchery, and callousness… so handsome! 

Draco and Eva watched as their sizable refinery that had been working as rapidly as it could to purify materials began to suck in torrents of Worldly Energy far more ferociously than any of the previous buildings. 

Its size expanded greatly, going up to five times its previous self before it began to slow down. Worldly Energy still flowed into it for another five minutes before it finally stopped, leaving the White-Haired Duo greatly curious as to what had happened exactly. 

They lowered themselves down to the level of the building and noticed that while its outer appearance was much the same, it now sprouted a mysterious chrome-like design that was a bit too futuristic for a Western Fantasy world.
