  We further investigate the probability that, weak CP phase originates in a
certain geometry. We find that our postulation on weak CP Phase gives strict
constraints on angle gamma in unitarity triangle DB and the element Vtd in
Cabibbo-Kobayashi-Maskawa (CKM) matrix. The predicted Vtd is about 0.0086 and
gamma about 75.3^o with the very narrow window respectively. These two
parameters can be used to test our postulation precisely in near future.
