Ninth Pin and Great Grandmaster were two realms in the fantasy novel " The Sword Snow Stride ", which was written by an online writer, Fenghuo Xi Zhuhou. In the novel, the difference between the two was huge. The nine grades were divided into lower, middle, and upper grades, corresponding to the Vajra Realm, Profound Finger Realm, and Celestial Phenomenon Realm respectively. A Great Grandmaster was at the peak of the First Stage Four Realms, and above that was the Land Immortal Realm. In the novel, a grandmaster could be said to stand at the peak of the martial arts world, possessing unparalleled strength and status. Although a Level Nine expert was also a top figure in the martial arts world, there was still a big gap compared to a Great Grandmaster. In the novel, after Xu Fengnian became the Prince of Beiliang, he was already a Level Nine expert. However, he was still a little powerless against a martial grandmaster like Deng Tai'e. This also showed that the gap between Rank-9 and Great Grandmaster was very large.
