Lin Fuzhao, a soldier on the frontier, accidentally activates the "Lucky Red Envelope System". Every time he completes a good deed or a key event, he can trigger a random red envelope, which contains martial arts secrets, thousand-year-old medicinal materials, rare treasures, etc. He started his counterattack by scavenging on the battlefield, and integrated the fragments of "Nine Layers of Strength" in the red envelope into a top-notch skill. After rescuing Su Tan, a businesswoman in trouble, the two became bound by the red envelope system. On the one hand, the war on the border was tense, and Lin Fuzhao relied on the "Black Iron Sword" and "Heavy Rain Quiver" equipped with red envelopes to achieve extraordinary feats; on the other hand, Su Tan's caravan rose due to his "Business Notes" red envelopes. The two went from using each other to truly falling in love, and finally worked together to quell the border chaos, achieving the legend of "the sword breaks the nine heavens, and the red makeup determines the world."
