Duncan completely forgot about the mortal peril his life was in inside the garden region.
He only cared about creating his own sword art as time passed. By slowly perfecting his own findings, Duncan began to form an embryonic sword art of his own creation.
In this, he began integrating all the insights and knowledge he had learned so far. Duncan wanted to create a sword art that would shine as the pinnacle of the Sword Dao. Even though he knew that it was a tall order for him to accomplish, Duncan didn't hesitate at all.
He wanted to create a sword art that only contained concepts of swordsmanship in it. A pure sword art that didn't integrate anything from other daos. A pure sword art made by a heart that had the pursuit of the ultimate of sword dao as his ideal.
