Continuing to test out the different Daos he had comprehended on the inside of the guardian demon beast's mouth, Xuan Hao ended up discovering one Dao that the guardian demon beast was weak against. On the negative side, this Dao just so happened to be the Dao of Alchemy. Not really a Dao used for fighting nor one he had ever used for fighting. At most he might have tested it out for fun once or twice when he was bored, but never to the point of developing techniques or researching ways to use the Dao of Alchemy in battle.
After all, he had so many other Daos that were far more suitable for combat, why would he choose to use the Dao of Alchemy for fighting?
