I'm Just a Corporate Drone, So Why Must I Save Humanity?

My name is Zeng Tai. I'm a “decent guy” whose love life has gone nowhere, a wage slave who works overtime every day until he questions the meaning of life, ground down and exhausted by his company. I burned through my youth and gave it everything I had, yet I still couldn't get myself or my family out of hardship. Then, one day, while I was cheerfully “working like an ox,” a super-powerful intelligent life-form from the future suddenly latched onto me and said I had to save humanity. Ha! What a joke! I can't even save myself and my family, and I'm supposed to save humanity? I flat-out refused! But this intelligent life-form was no ordinary woman. She was fierce, had legs that were 1.2 meters long, and was remarkably good at arguing her case. Most importantly, she could take me through portals in time and space to different worlds. I could get miracle drugs to cure my family's terminal illnesses, obtain all kinds of advanced technology and start a world-class high-tech company, then build a powerful team and produce superweapons to beat up the mysterious enemies trying to wipe out humanity... I could escape poverty and mediocrity and reach the pinnacle of life... There were just too many benefits. I couldn't refuse! So, “with tears in my eyes,” I accepted the mission and went from an ordinary workhorse to a fantastical “superhero” who saves humanity.
