Alien Invasion, Nuclear Fusion, I Was Broadcast Live

Aliens invaded and colonized Water God and conducted experiments, creating the illusion that only Chen Wei was left in the world, and broadcast it live around the world! Just when the whole world looked at him like a clown and thought he could play with Chen Wei's life at will, he activated the system. System: One year from now, there will be an alien alien civilization that will attack Mercury. Planet Mercury will be destroyed, and the alien species will take away all the matter from Mercury! At this time, Chen Wei believed the fact that all mankind had left, and he panicked! System: I will help the host create a cosmic intelligence fleet within a year to resist alien civilization and leave the earth! "Oh my god, he is actually creating nuclear fusion alone... And is studying the space battleship drawings!" (PS: This is an imaginary world with no country. The whole world is controlled by various chaebols, and chaebols are the most powerful force here!)
