MTL - The Supernatural Skill System of the Emperor Engine - Chapter 121

When an alien ambassador crash-lands in Tim's backyard and demands, 'Take me to your leader,' the 12-year-old does what any kid would do: he points to himself and says, 'That’s me. I’m the King of Earth.'Now, thanks to a hastily signed treaty (and a promise to hand over Jupiter), Tim’s got an armory of world-ending alien tech, an invulnerable Planetary Base in his backyard treehouse, and one tiny problem: nobody told him ruling a planet would be this hard. Between conquering Earth, fending off hostile fleets, outsmarting intergalactic bureaucrats, and explaining his absences to his Trekkie dad, Tim’s in way over his head. But if he can’t bluff his way through alien diplomacy fast, humanity might end up as collateral damage.“King of All I Survey” is a fun, heart-pounding sci-fi adventure where one kid’s lie decides the fate of Earth—and homework is nothing compared to intergalactic war.
