  This is the final one in the series of papers where we introduce and study
the $C^*$-algebras associated with topological graphs. In this paper, we get a
sufficient condition on topological graphs so that the associated
$C^*$-algebras are simple and purely infinite. Using this result, we give one
method to construct all Kirchberg algebras as $C^*$-algebras associated with
topological graphs.
