During the troubled times of the Republic of China, Liu Ruyan, the top brand of Fengqi Tower in Nanjing, was forced to be involved in a thrilling espionage whirlpool after rescuing the seriously injured revolutionary Shen Mobai. What was supposed to be a romantic relationship has become a bond of life and death in troubled times.
The two worked step by step during the Japanese army's encirclement and suppression and the spy's pursuit. From the smoke and rain of Jinling to the loess of Yan'an, they used their lives to practice the oath of "harmonizing the piano and the harp, and returning to the same faith" in the smoke of gunpowder...
He is the sharpest blade in Yan'an and the enemy's most perfect chess piece.
When Shen Mobai discovered that the enemy who looked exactly like him was actually his brother Mo Xuan, who had been separated since childhood - he was trained by the Japanese army as a killing machine, but he still remembered the covenant of glass beads buried under the jujube tree.
The fireworks in Fengqi Tower hide the secrets of home and country, and the red lights on the Qinhuai River reveal bloody loyalty.
"Brother, kill me..." The two souls in his body were tearing apart. One side was the killing instructions implanted by the Japanese army, and the other side was the deep-rooted memory of his family and country.
When poison bombs were thrown at the water source of Yan'an, the blood on his wrists was stained with red loess: "This time, I am finally myself..."
Twins in troubled times, both inside and outside the mirror have loyal souls; the blood-colored glass will eventually illuminate the mountains and rivers with clarity.
