A black hole X-ray binary produces hard radiation from its corona and disk when the accreting matter heats up. During an outburst, co-evolves with each other. However, such evolution is still unclear in both geometry dynamics. Here we report unusual decrease of reflection fraction MAXI J1820+070, which ratio coronal intensity illuminating to reaching observer, as observed contrast during decay phase. We postulate a jet-like model, can be understood standing shock where material flowing through. In this dynamical scenario, signature corona's bulk velocity. Our findings suggest that get closer hole, might outflowing faster.
