Nine at the top means:

He dissolves his blood.
Departing, keeping at a distance, going out,
Is without blame.


The idea of the dissolving of a man's blood means the dispersion of that which might lead to bloodshed and wounds, i.e., avoidance of danger. But here the thought is not that a man avoids difficulties for himself alone, but rather that he rescues his kin-helps them to get away before danger comes, or to keep at a distance from an existing danger, or to find a way out of a danger that is already upon them. In this way he does what is right.
