Apocalypse Survival: I Seek Immortality Through Deduction

After enduring more than 400 grueling days, the project was almost ready to launch. Then the team was disbanded on the spot, leaving me alone to man my desk with my jerk of a supervisor. By day, I couldn't finish fixing the code. By night, he watched women on livestreams. I thought this was just how my life would go, until a transmigration threw everything into chaos. We used to be boss and subordinate. Now our fortunes have completely reversed: I'm a medicine boy running errands, while he's a high-and-mighty heir. And just my luck, there's a zombie outbreak in ancient times. No water, no electricity, no storage space, no guns or cannons, and no stockpiled food. The boss who used to order me around? Now we're each on our own. Watch me thrive in the apocalypse!
