The human realm was divided between five great nations which all had a number of Kingdom/cities or countries/states in it.
According to history and the words of old wise people, the earth is divided into Five Great Realms by an invisible wall after the great war of gods, human and demons.
After much bloodshed, destruction and suffering, the great god of war sealed off the demons and the beasts in another realm. By then however, many countries had perished.
To make sure the Demon Lord doesn't return and destroy the earth all at once again, the Great War God used all his power to create five mysterious stones and buried them in five place in the human realm then formed barriers to divided the earth in five. No one could leave or enter these barriers. It was this named The Five Great Walls.
The human realm was divided into five great nations and each nation's protective stone was guarded by the strongest people in that nation for if the protective stone fall into the hand of a demon, it will transform into one of the five keys that unlock the seal of the Demon Lord.
According to history, only four of five nations have located their protective stone
The Black Dragon Nation, the fourth of five nations have yet to discover her protective stone even after millions of years. Some believe that the Great War God only created four protective stones and others that their stone have been found by a demon and have transformed into a key which would soon result in demons and beasts terrorizing the Black Dragon Nation.
However, until date, no one have seen what a demon or it's beasts looked like neither does anyone know about a few years old boy that just crossed over from another world.
* Black Dragon Nation, Black Diamond Kingdom, Xiao Sect, Central Core City, Patriarch House *
The Black Dragon Nation is one of the five great Nations in the human realm and also the third in the ranks. It however had one misfortune. It does not have a protective stone. However, the Black Dragon Nation was well known for having some of the most beautiful places in the realm and also for it's abundance of resources
The Black Dragon Nation is home to two kingdoms and three Countries. Among them, in the Black Diamond Kingdom, one of the two kingdoms, was occupied by the Chinese and ruled by the Xiao Sect, the second strongest Sect in the Black Dragon Nation.
The early leaders of the Xiao Sect, after many years of exploration and wandered found a whole uninhabited land and claimed it as theirs. Today, the Xiao Sect is well known for having the most treasures and resources. Some even believe that the land they settled in was actually the dueling place of ancient gods and that was why it had so many treasures and resources
However, in terms of cultivation and martial artists, the Xiao Sect was rather lacking behind as the disciples of this Sect didn't have much talents in the path of cultivation. The few they had were greatly valued by them and actually powerful.
Even with this low level of protection, not a lot of people dared to offend the Xiao Sect. It was said that Sixteen years ago, a group of bandits attacked the Xiao Sect and killed a lot of people also stealing a lot of valuable treasures. They escaped with these treasures however at midnight, cries and begging was heard from the wilderness. When powerful cultivators got there to investigate, they found the bandits beaten senselessly on the ground all injured, their marginals shattered and cultivation crippled.
They kept saying that at the stroke of midnight, they were attacked by unknown martial artists who didn't take any of the stolen treasures
That was an unbelievable story but since no one came out to clarify it, everyone believe that the Xiao Sect was really the dueling and death place of a powerful god whose spirit was yet to depart from earth and had gone to take back his stolen treasures
Ever since, no one had gone to cause trouble in the Xiao Sect and thus, the Sect was very prosperous.
For this reason, the Xiao Sect became the the ruling sect of Black Diamond Kingdom.
