[No cp + system + live broadcast + time travel + leading civilization] When countless incredible pictures appear on the global network through "live broadcast"! Panic! Confusion! And the passion for the unknown!

Every live broadcast is a survival show and a warning to Blue Star viewers! My success will bring strength and hope to Blue Star to resist the invasion of other worlds! My failure may accelerate the demise of Blue Star! [Live broadcast barrage]: "Holy shit! He actually killed the demon god?!" "It seems like this technique can be practiced in reality!" "Look!
