Han Dong was unaware that [Young Master - Gracy] had been chosen by the clown,
currently observing the "Black Card" reward issued by the circus (raising his head every four seconds to glance at the stage).
1. The card's material is of absolute premium quality, something Han Dong has never encountered, with a tactile sensation of fine granules, seemingly constructed through micrometer-scale dodecahedral grains.
Viewed from different angles, the different grain faces refract a unique luster, mysterious and profound.
It can even transmit a vast amount of information through a special conversion mode between the cards... or rather, the card itself is a special hard drive using special grains as a medium, with different faces refracting as output ports.
2. The particles making up the Black Card resemble burning coal, constantly emitting black smoke, seemingly flashy, but this black smoke can effectively shield external perception.
