A conjecture to prove Riemann hypothesis

In view of relations between Riemann hypothesis and quantum theory according to the Hilbert-Polya conjecture and further investigations its proof is important for quantum physics. I conjecture to prove Riemann hypothesis according to Riemann's saddle point method to derive zeta function. This is a direct method to prove Riemann hypothesis related with my previous topological approach to analytic number theory and Riemann hypothesis.
