Brother Zheng, Qin's Territory Is Too Small

I've read thousands of time-travel novels, but this is a first—transmigrated WITH my car! While others get golden fingers and cheat systems, I'm stuck in ancient Qin with a modern vehicle literally wedged under my arm like an awkward weapon. No manual, no divine guidance, just me, a confused traveler, and the future First Emperor who's about to discover that his empire could be so much bigger. Sometimes the best cheat code is the one you never expected.
