Li Mo's life originally only had three things: finding food, working, and surviving.
Until the most mysterious organization in the country came to visit: "A monthly salary of five thousand, including food and accommodation, do you want to do it?"
He thought he was just working as a security guard, but after signing the agreement, he found out that what they were going to train was the "shadow" that guarded the country's secret line.
The instructor looked at his shabby report card and shook his head: "I failed in combat, just met shooting standards, and barely passed in reconnaissance... Why do you stay?"
Li Mo lowered his head: "I know better than anyone how important it is to have enough food. Now, I want more people to have enough food."
Ten years later, a codename was circulated in overseas intelligence networks: "Scabbard." No one has seen his face, they only know that he always appears in the most ordinary places - noodle shop clerk, construction site worker, cleaning uncle...
What he protects is not confidential documents, but something more important: the right of every ordinary person to continue their ordinary lives.
From trash cans to national borders, how an orphan protects the noisiest human fireworks in the most silent way.
