There are three ancient books. One is the original Infinite Sword Canon, and one is a hand-copied version of the Infinite Sword Canon, recording the insights of dozens of Sword Tao Masters and Grandmasters on the Infinite Sword Canon, from Infinite Sword Intention to derived divine abilities, and even the Infinite Tao Rhythm, everything is covered.
Comparing with the Immortal Nine Swords, the two types of Infinite Sword Intentions cannot be said to be identical, but they are very similar.
Having wandered in Zhaoqin and obtained the Infinite Sword Intention for free, Exile refined its essence and removed its dregs, to form the Unbounded Sword Intent of the Heavenly Sword Sect.
However, for the deeper Infinite Tao Rhythm, Exile did not leave any statements, and it could only be understood by later generations themselves.
The pit is too deep; the successors all fell into it.
