Amid the bustling, tangled streets of Shanghai, Zhang Shuo, codenamed "Tablecloth," weaves through the crowds. Dressed like an ordinary citizen, he has eyes as sharp as an eagle's, as if he can see through everyone's disguise. Zhang Shuo was once an agent in the 21st century, but after an unexpected transmigration to Republican-era China, he became one of the lowest-ranking agents in the Military Statistics Bureau. Yet he has no intention of settling for an ordinary life. With the intelligence of a transmigrator and the help of the System's "Scanning Eye," he gradually makes a name for himself in the shadow war.
