Among martial artists, those who can reach the Realm of Micro are very few, even those who advance to the Bone Forging Realm among the younger generation are rare. Most are from the older generation, as this requires a vast amount of combat experience and trials of life and death to comprehend such a realm.
Even he only barely reached the Middle Tier of the Micro Realm after advancing to the Blood Coagulation Realm, and now, even as a legion commander, he has yet to grasp the threshold of the Micro High Rank.
The Black Obsidian Martial Arts Hall, however, allows a Middle Tier Micro Realm individual to guard the arena. Unless the challenger reaches the High Tier Bone Forging Realm and also achieves the Middle Tier of Micro, it would be very difficult to defeat the defender of the Black Obsidian Martial Arts Hall.
