Come On, I'm a Paratrooper. I Just Want to Rejoin the Team

[Scheming, talkative male lead + No female lead + Sci-fi + Interstellar war + Mecha + Futuristic fantasy + A lone journey across a thousand miles] Thirty years ago, an interstellar army suddenly appeared in the solar system and launched an invasion and massacre of Earth. The invaders had set the wheels of humanity’s extinction in motion. Thirty years later, rookie paratrooper Li Ruisheng is accidentally air-dropped onto an enemy-occupied planet, where he saves one of their own main battle mechs that’s nearly beyond repair... “Come on, I’m just a paratrooper trying to get back to my unit.” His answer was an endless barrage of enemy fire. “Consider this a friendly warning: I’ll have to turn your entire otherworld upside down and then go home.” And so, on the way back to his unit, Li Ruisheng also managed to bring humanity’s extinction countdown to a halt. After all, how could he return to a home that no longer existed?
