Mo Dian
This is a paradise for a group of people and a hell for a group of people. It is like a black hole, with countless vines sticking out from it. The vines glow with a strange green color, tightly surrounding the people here, making them numb, cold-blooded, and cruel. Some of these people are killers, doctors, scientists... But they are all elites in their fields. This group of people are fighting here for the "fun" and the status of the strength they represent. In the original society, as long as this group of people are willing, with their wisdom, knowledge, status and money, it is not a problem. However, life without opponents for many years is boring and tasteless, so this place is here, and they all come here to find "fun". Everyone here wants to climb up and reach second place, because the number one here will always be Mo, the founder of this place. A mysterious man who always pursues strength.
The group of people also have status in society, maybe they are waiters or cleaners... But they all hide their true identities.
This is Modian Modian. Only its members know its location. It is far away from people's sight, vague, but within reach.
