Jing Wei was someone who had always pursued to learn more about weapons and how to make them. It was the goal of the Jing clan and what most of their people had inherited as well.
His pursuit of weapon refinement and forging was so high that even his Dao Embryo was in the form of a hammer. In order to perfect his understanding of weapons, he took them up, even going so far as to comprehend his own sword intent.
For he knew, to make a good sword, he needed to first learn it.
Jing Wei was no different from the many that had come before him. But he was the first one who had reached the level of making an Immortal weapon.
Reaching the Immortal Ascension realm was a mystery for most. There was no single concrete method of reaching it and most that did so was due to luck. There were many theories as to how one reached that realm.
