Within the Dragon Soul Continent, the ongoing story content always revolved around the devils attempting to destroy humans. They seek to turn this beautiful world into a scary, bloody and dark world like theirs. While lurking in the darkness, they tempt humans with their deceptive words and irresistible rewards. Once they fall into temptation, the devils would immediately gain a foothold to spread destruction and despair.
When there's light, there will be darkness; similarly to justice and evil. Some may choose to defend the world as a protector, and some may choose to watch the world burn.
The Summoning Ritual was a byproduct of people who wanted to watch the destruction and chaos of the world. The ritual would tear down the nine layers of space between hell and earth using spiritual energy, forming a spatial tunnel for the devils to pass through freely into the world.
