虛數

虚 = 业 + 虍 : Xu Xian (xu) and the bullfrog (业) were preparing for a football game in front of the space station (Ø1) and had already painted eye black stripes (虍) onto each other when suddenly a black hole (虚) appeared and sucked their eye black off again before collapsing.

数 = 娄 + 攵 : Sheldon Shrimp (shu) occupied a lunar mansion (娄) inside of the space station (Ø3) although he knows that it is to be torn down. Outside of his lunar mansion the construction (or rather destruction) workers are already counting (数) down from ten. When they count (数) zero, they will start taking down the whole thing with their sledgehammers (攵).
