Swordless Realm:: 自分 transcends the need for a sword
Pure 灵:: 自分 has transcended 灵引, becoming a 灵
In his hand, his sword isn't just a tool, it's the manifestation of swordsmanship itself
While 相手 can make 2,8,21,or 100 moves, all 自分 needs is 1 action to nullify them, targeting only its essence/灵引 & leaving only 灵
自分's movements leaves/引 no cause/引, as 自分 only 引 behind the 灵, transcending causality/引 as 自分 accepts transience/nirvana, dissolving 相手's attacks & absorbing them as 灵
