The Shaodong family of Peking Silk Village could have followed his father south to avoid the war, but when the Japanese army broke through the city gates, he chose to stay in his hometown. He used his identity as a businessman as a cover and transformed into an underground party intelligence agent. From delivering combat maps to outsmarting Japanese raids, from blowing up transportation lines to rescuing compatriots, he forged his iron-blooded loyalty amidst the hail of bullets. When close friends sacrificed heroically to protect everyone, and when they were tortured but still kept secrets, the Dynasty used their flesh and blood to build a secret Great Wall of resistance behind enemy lines. After eight years of bloodshed, he finally welcomed the dawn of victory. He used his blood to write a legendary epic about an ordinary person's awakening, struggle and growth in troubled times.
