Another Earth Escape, Ice Escape, and Moonlight Escape, and now, even Sword Escape is here...
No, that's not quite right. In fact, the technique of Sword Escape is recorded in the "Nine Luminaries Sword Scripture". Originally, the Sword Sect's sword energy was cultivated by borrowing star power, and the 'light' formula of the Neon Light and Shadow technique includes methods of borrowing light for sword control and tunneling with the flying sword.
So actually, when Tie Dan reached the Golden Core Realm and could condense Taibai Sword Light, he could have used the Taibai Sword Escape. The only reason he didn't use this move was that he was poor and didn't have a handy flying sword.
Additionally, to be honest, it wasn't very necessary, as Sword Escape not only requires a flying sword to borrow the light, but also requires one hand to pinch the formula and control the sword. Moreover, with that effort, you might as well just charge in and kill the person with one sword strike...
