I Transmigrated as Gin: Too Many Undercover Agents, What Do I Do? Join Them If You Can't Beat Them!

A wage slave from modern-day China discovered that he had transmigrated into the body of Gin, and felt his future was bleak. The wage slave said he didn't want to work overtime and just wanted to slack off. But as soon as he saw the paycheck, he thought, "Hmm, maybe working nine to nine, six days a week isn't so bad after all."

A few things to know before reading:

The story uses original settings. Gin is a Chinese spy who took APTX 4869 about thirty years ago and shrank. After arriving in Japan, he lost contact with China. The protagonist only managed to get in touch with China after transmigrating.

There will definitely be out-of-character moments!

There will definitely be an overwhelming gap in intelligence. The characters won't be smarter than the silly author.

It's been too long since I read the original, so I don't remember all the details. Please treat anything that doesn't fit as an original setting.

The required golden finger for transmigration: a System. However, the System doesn't feature much.

There probably won't be a main pairing, at most unrequited feelings, and romance will be a very minor element.

(Gin: Our focus is on building our careers, promoting development, making progress together, and working toward prosperity. Who has the time to talk about love? Isn't the fictional world more fun?)

This is not a rescue story. Only Matsuda Sweet survived from the Police Academy group, and the characterization has been heavily changed.

Theme: Three years undercover, then three more years, and then another three, until at last becoming the BOSS
