A semi-analytical method is provided for investigating the cold GRMHD inflow/outflow along large-scale, hole-threading field lines for the first time. The solutions show the complete process of the formation of relativistic jets form a rotating black hole: from how the black hole rotational energy is extracted outward via MHD Penrose process, to how the extracted outward energy continuously carried out from inflow to outflow region, with the conversion from Poynting-to-Kinetic energy take place on the way.
