Here is a less formal introduction:

I traveled through time and seemed to be an employee of a company.

Wow, that's a lot of salary!

The alarm sounded.

Asking me to suppress the minions? What the hell is this company?!

The following is a serious introduction:

I am Ye Lan. The best employee of Lobotomy Corporation in X0XX. Miss Hod doesn't even need to do core suppression after seeing me.

But no one in the company knew that I was actually a spy from a company in a world even outside the ruins. (Of course, Miss Angela might know this, but she didn't tell anyone, so no one knew.)

But besides this secret, I have another one.

A secret that even my real company doesn't know: I'm a time traveler. (But maybe I've told Miss Angela about this in one of my previous loops.)

In 1961, before the Berlin Wall was built, East Germany was rife with undercurrents. Lin Zou, a modern-day office worker, transmigrated into the East Berlin black market, becoming a heavily indebted errand boy. His only advantage was a mediocre intelligence system. With the Berlin crisis looming, the Berlin Wall about to be erected, and the new economic reforms and the East-West German trade boom approaching, he used fragmented memories and deduction to preemptively plan: stockpiling and cashing out, cross-border reselling, exporting optical instruments, arbitrage in chemical machinery… He navigated the cracks of the black market, Stasi surveillance, and CCM trade to amass wealth. From a black market underling, he climbed to become the "King of Intelligence," influencing the winds of the Cold War. Until the Stasi came knocking—they wanted him to be an even more dangerous pawn… [Foreign background + era + intelligence system + high IQ] This book is also known as: *Transmigrating to East Germany: Starting with a Life Owed to the Black Market*...
