Space-time is not as smooth and straight as most people imagine it to be. It is filled with curves, folds, and creases, which go unnoticed due to their scale. Most of the time, the three-dimensional geometry constructed using Euclid's axioms is sufficient to understand this space. However, this is always just an approximation.
And yet, the Wanfa Sect possesses a series of spells that change the space-time metric, allowing one to transcend the twists and turns of space-time with a three-dimensional body. But to achieve this, one must be able to calculate the true face of space-time.
This is the secret of high-dimensional swordsmanship.
Wang Qi practiced his swordsmanship several times, positioning his swordsmanship at a fourth-dimensional level, with fifth-dimensional sword moves serving as killing moves. Apart from a few absolute skills like the No Mistake Sword Net, he had converted all his sword moves into high-dimensional swordsmanship.
