Xu Mo, an ordinary college student with an iceberg personality, accidentally activated a super black technology system from the future - the "Dare King System" in a truth or dare game. From then on, every choice he made turned into an interstellar adventure. Under the guidance of the system, Xu Mo discovered that the earth is facing a civilization test from the interstellar federation, but humans know nothing about it. What's even more frightening is that the test standards are extremely strict: those who fail will be regarded as uncivilized civilization and be directly exterminated. As the selected "Adventure King", Xu Mo must complete the bizarre tasks issued by the system within the specified time - from conquering the alien black market to outsmarting interstellar pirates, from participating in a cosmic beauty contest to cracking the black hole code. Every step is full of dangers, and every step is full of laughter. He takes the system to wander among the major forces in the galaxy. On the surface, he is a funny adventurer, but in fact, he is secretly disrupting the alien forces' plans to infiltrate the earth. When everyone thought he was just playing a large-scale real-life game, Xu Mo had quietly become a key figure in rewriting the destiny of mankind. A seemingly absurd truth or dare begins the interstellar journey.
