We experimentally and theoretically investigate the Rydberg six-wave mixing (SWM) process in 85Rb atomic vapor. Through comparing the center frequency positions of resonant Rydberg SWM signals with different atomic densities, atomic levels induced by van der Waals interaction are observed. Meanwhile, such SWM process which is sensitive to blockade can be modulated by the self-dressing effect and/or external dressing effect. In addition, the Rydberg eight-wave mixing process can be obtained if the power of the external dressing field is low. Such blockaded multi-wave mixing process has potential applications in multi-channel quantum information.
