Wizard: I can refine everything

Endless star realms, plane wars, wizards' floating cities conquered one world after another.
Wizard academy, bloody exams, and the sky-high wizard tower transported batches of wizards.
Richard, who became a wizard apprentice, opened the miracle furnace deep in his soul. As long as he continued to refine the raw materials, he could gain knowledge and skills...
The weapons of veterans who had fought for hundreds of battles could be refined into martial arts handed down from generation to generation.
The secret notes of ancient wizards could be refined into lost knowledge.
The remains of brutal monsters could be refined into monster bloodlines.
In this great age of navigation in the wizard world, Richard will eventually become a leader of the times.
