He could comprehend all manner of wondrous techniques and Dao Marks to refine Gu spirits, and refine plants, trees, mountains, stones, divine birds, and strange beasts into Gu worms. He could then use Gu worms to create killing moves and forge the Great Dao. The Solar Ancient Scripture? The Taiyin Ancient Scripture? All those ancient scriptures and mystical arts? Refine Gu!
