"Alright, that's the introduction about the ghost." the Green Family Patriarch clapped his hand. "I don't want to explain too much about them. You won't be meeting any ghost more powerful than an unranked ghost."
"Why?" Leon frowned. He felt that the Green Family Patriarch was not serious when teaching them.
"Because there's only 1 rank 1 ghost among 100 unranked ghosts so far," the Green Family Patriarch replied calmly. "Unless you're extremely unlucky, you won't be seeing that rank 1 ghost."
So rare?
The children were surprised and then felt that it made sense.
If there were so many rank 1 ghosts, there would be more casualties in various cities and they wouldn't be able to handle it like they had done so far.
So they took it for granted.
