In explaining the spectral properties of active galactic nuclei (AGNs) and X-ray binaries, it is often assumed that they consists of a geometrically thin, optically thick disk and hot, optically thin corona surrounding the thin disk. As for a model of a corona, we adopt the simulation data of three-dimensional MHD accretion flows, while for a thin disk we assume a standard disk. We perform Monte Carlo radiative transfer simulations in the corona, taking into account the Compton scattering of the soft photons from the thin disk by hot thermal electrons. We can reproduce the emergent spectra which are consistent with those of typical Seyfert galaxies, and we also find the rapid time variability in X-ray emission spectra, originating from the density fluctuation in the corona.
