Ryu had never really thought about it before, but no matter how you looked at it, the blade of the Spiritual Severing Realm was indeed a sword. Though it had no hilt or handle, there was no mistaking the style of the blade. The question was if this was by design of the Heavens or if it was something that Ryu had subconsciously done.
In order to form the Severing Blade, one needed to accumulate all the qi they had gathering during the Qi Refinement Realm, expel it, and then use your qi control to meld it.
