Most cultivators were able to reach a State of Mind at the level of 2-dan Heart of Tranquil Water.
But to exceed that level was extremely difficult.
It was said that only upon reaching the level of a 4-star master teacher would one have the chance to make the breakthrough.
Heart of Tranquil Water only allowed one to remain impervious to external factors. The higher realm to that was 'Vanquishing Facade, Lucid Mind' that Luo Qianhong just exclaimed.
Upon reaching this level, one would be able to peer through chaos to see the crux of the matter. At the same time, with a clearer mind, one's analytical power would grow substantially stronger.
Even though it was far from a match for the Eye of Insight, it was useful in the sense that it provided a master teacher with a greater degree of rationalizing abilities.
