  With analyzing the mass function obtained by solving Dyson-Schwinger
Equations, we propose a cut-off independent definition of quark condensate
beyond chiral limit. With this well-defined condensate, we then analyze the
evolution of the condensate and its susceptibility with the current quark mass.
The susceptibility shows a critical mass in the neighborhood of the s-quark
current mass, which defines a transition boundary for internal hadron dynamics.
