BLACKBOW cleverly combines the fantasy world in the game and the skill characteristics of the game characters ,by its consistent black-tech techniques, creating an explosive water curtain show on the shore of Daming Lake. It brought a visual feast about DNF IP to the audience and game players. At this conference, BLACKBOW designed a entity light column device with a diameter of 2 meters and a height of 6 meters, located at the corner of the island in the middle of the Daming Lake. BLACKBOW uses programming to set up linkage devices for sets of multimedia performances. The light column device has always been a dynamic hourglass shape from day to night until the conference show.  When the yellow sand flows to the last drop, Seria Kirmin waiting in the water curtain will take that drop of sand on  and transform it into the Arad in her hands. The Arad will bring us into its world with continuing growth. As well as, BLACKBOW uses AR vision technology to bring viewers a more realistic perception experience.
