Hemostatic devices for promoting blood clotting can include a substrate, a hemostatic material disposed thereon such as kaolin clay, and a binder material such as crosslinked calcium alginate with a high guluronate monomer molar percentage disposed on the substrate to substantially retain the hemostatic material material. A first circuit section has an accumulator for storing hydraulic pressure, and a control valve for controlling a passage for delivering fluid from the accumulator to an actuator. When the morphologic change status of the character satisfies any of the evolution requirements provided to the next evolution stage of the current character, the game machine sets the evolution morphology correlated to the evolution requirement as a character morphology.
