[Myriad Worlds] [Handing Everything Over to the Nation] [Invincible Protagonist] [Feel-Good Story] [Black Technology] After his ex-girlfriend drained his savings and coldly dumped him, Chen Ji was heartbroken. Then he unexpectedly bound himself to a portal connecting all worlds! Faced with the temptation of conquering the world, he instead called the military district: "Hello, I found a treasure. I want to hand it over to the nation!" From then on, the world's timeline went completely off the rails! The nation swiftly established the [Myriad Worlds Strategic Resources Department], and Chen Ji was promoted to chief transmigration consultant! Behind him stood a million-strong army, a top-tier think tank, and the republic's finest scientists! When a modern unit equipped with exoskeletons and wielding "Gatling Bodhisattvas" dropped into the world of Mr. Vampire, Uncle Nine was dumbfounded. "Taoist priest, times have changed. Science is the way to exorcise demons!" When T-virus samples were sent back to a domestic lab, Resident Evil became a catalyst for biotechnology! While Iron Man was still hammering away at scrap metal, our controlled nuclear fusion had already lit up the first space city! Chen Ji: "My mission is to represent the nation in conducting 'friendly' resource surveys and cultural exchanges across the Myriad Worlds." Thanos: "??? You call this a cultural exchange?!"
