A Rocket Launcher from the Start, and You Call It a Mystery Box?

Gu Qing transmigrates to a parallel world and, to survive, has no choice but to become a mystery-box streamer. Little does he expect to bind himself to an utterly unreliable System... "Opening mystery boxes brings good luck and rewards? That's a thing? Open them, of course I'm opening them!" He thinks some cheat-code-wielding god has picked him, but his "beginner's gift pack" gives him an RPG launcher! When a rocket explodes over the sea, the whole internet goes wild! [I thought this was scripted, but this streamer is actually for real!] [Rocket launcher fishing! That's freaking awesome!] [Oh no, oh no, this streamer is way too cocky. He deserves life in prison, at the very least!] Just when everyone online thinks he's done for, it turns out he's bought himself a second life. Back on the air, he opens another mystery box. A pair-bonding dossier? What's that supposed to be? A treasure map from the Taiping Heavenly Kingdom? Is it real? Fifty jin of white powder. How many times over is that enough to get me executed? A biohazardous virus? Come on, don't do this! After he opens mystery boxes containing all kinds of bizarre items, the whole world goes wild. Government agencies even set up shop in his livestream, eager to see what he'll do next. And then... The contents of his mystery boxes get more and more outrageous. Gold, advanced technology, alien data, entrances to four-dimensional space... They all appear in his livestream in mystery boxes, leaving netizens and the whole world stunned!
