Spy World: Agents Begin with Sign-In

Six years ago, Lin Hongyuan transmigrated into a world combining several spy dramas and joined the Fuxing Society's Special Services Division. He broke up spy networks one after another, earning himself the name "Shadow Demon." Later, unwilling to get caught up in internal power struggles, he retired.

When war broke out, the ace returned to the field. He assembled a team and plunged back into the world of espionage. With the Sign-In System at his side, he became more formidable than ever, capturing Takeuchi Geiko and stopping enemy ships on the Yangtze River, where he wiped them out.

Operating undercover in the East China Sea, he wove an enormous spy network deep into the enemy's heart, sending out vital intelligence without pause.

He served as an instructor at several successive Military Statistics Bureau training classes, teaching students such as Yu Zecheng, Lan Yanzhi, and Ming Tai.

Takeuchi Geiko: "My biggest mistake was underestimating the Shadow Demon."

Dohihara: "The Shadow Demon was the greatest opponent of my life. It was my good fortune to die at his hands."

Dai Chunfeng: "Lin Hongyuan is the finest agent in the Xia Kingdom!"
