Something is Off

There was a rule at the Thousand-island Lake, a rule set by the Old Man of the Heaven Prison himself—no force could attack another one two ranks lower.

To put it simply, a Fourth-rank force could not attack a Second-rank one, and a Third-rank force could not assail a First-rank force.

The Liu Family now was a Second-rank force, the God-down Island a Fourth-rank one. The latter could not attack the Liu Family. Of course, the rule was lifeless but people could devise other means. If the God-down Island really wanted the Liu Family out of the picture, they could just say so. Any big shot of the God-down Island giving an order would lead numerous Third-rank forces to overwhelm the Liu Family.
