After the Green Lotus True Body advanced to Grade 11, Su Zimo obtained this horsetail whip Dharmic treasure.
However, there were extremely few lineage memories of this Dharmic treasure. He only knew that it was called the Primordial Unity Horsetail Whip and did not know anything else.
Now that Su Zimo was on the ninth stone step, the strange runes seemed to have triggered some sort of seal on the Primordial Unity Horsetail Whip, causing a lineage memory to surge into his mind.
The Yin Yang Talisman Sutra.
In that memory, there was a secret skill sutra that was divided into two sections with slightly more than 600 words.
However, Su Zimo could not understand a single word of the contents of those two sections!
That was because the contents were written by the strange runes he had seen previously.
