Mountain and Sea Divine Beast World, Xu Feng was outside Beast-slaying City, discussing Dao with the Hong Xian Furnace.
The Hong Xian Furnace was inside the Daoist Field, while Xu Feng's Divine Thought hovered above it.
The two had some significant differences in their understanding of Alchemy Dao; their alchemy systems fused and clashed with each other during the discussion.
Xu Feng's Alchemy Dao was like a formally educated system that also accommodated other orthodox alchemy systems, making his understanding of Alchemy Dao more comprehensive and concise.
Whereas, the Alchemy Dao system of Hong Xian Furnace was whimsical, but every move, in Xu Feng's view, was divinely inspired, hitting just the right spot.
After the exchange, Xu Feng resolved many of his doubts about Alchemy Dao, and Hong Xian Furnace began to construct a system of Alchemy Dao for the Human Clan.
Both parties gained a lot from the discussion.
