There was a forbidden area in the Ghost Clan. Other than the designated personnel, the other clansmen were not allowed to approach. However, there were always a few children at a curious and rebellious age. Ah Dou was one of them.
Ah Dou had "explored" the forbidden area with the children who had caused trouble everywhere since he was young. Unfortunately, the forbidden area was heavily guarded. They explored it many times but still could not enter. It was not until one time that Ah Dou discovered a canal near the forbidden area that they could swim in from there. However, the canal was narrow and the older children could not pass through. Fortunately, he was young and swam in with a few younger children.
There was nothing in the forbidden area.
