The Spy Shadow of the Twenty-Third Years of the Republic of China

Unexpectedly traveling through Shanghai in 1934, the 23rd year of the Republic of China, Su Yan awakened to the intelligence system and portable storage space. In troubled times, undercurrents in the concession are surging, and there are spies from all sides. The space can store food, medicine, ordnance and supplies; the intelligence system analyzes secret messages, deciphers hidden lines, and sees through the hearts and minds of all parties. Instead of showing off his courage, he lurks in the market, collects intelligence, hoards supplies, and contacts his comrades. When the mountains and rivers were broken, he used his meager efforts to travel thousands of miles to the mountains and rivers of his home country.
