The Bloodstained Siege of Niushan

[Adapted from the real historical events at Kunniu Mountain in Shiqian, Guizhou, in October 1934. The main characters and plot have been fictionalized.] In 1934, war flames engulf the border region of Hunan and Guizhou. Under Captain Wu Zhenshan, the 52nd Regiment of the 18th Division of the Red Sixth Army Corps resolutely lures thousands of enemy troops into the dead end at Kunniu Mountain to cover the main force's retreat. They endure ambushes at mountain passes, treks through torrential rain, and shortages of food and medicine. With the help of local villagers, they hold their position, only to become trapped in a deadly cage sealed by clouds and mist.

The battle is rife with spies. Zhao Huaizhou offers a plan in a crisis and deciphers a coded message, revealing the identity of "Nightingale." Shen Mengwei makes a mysterious appearance, teetering on the edge between redemption and betrayal. Wu Zhenshan directs the battle and unmasks a secret agent, then engages in a breathtaking clash of intelligence and a desperate struggle to seize evidence against Gao Junfeng, a military intelligence liaison. When their ammunition and food run out, the soldiers hold fast to their belief that they would rather die than harm civilians. They refuse to fire on their coerced compatriots, smash their weapons, and leap from the cliffs into Hujing Valley, forging a monument of spirit with their flesh and blood.

With the smoke of battle not yet cleared, bugler Chen Tiefeng, who survived the leap, carries tokens from his comrades and sets out on a perilous journey to fulfill the martyrs' last wishes. Relying on the courage honed on the battlefield, he outmaneuvers the enemy at every turn and searches the forests of eastern Guizhou. He survives ordeals including a fight to seize evidence at the foot of a cliff and a deadly showdown in a ruined temple, all to uncover the truth about the martyrs and build a memorial monument. He devotes his life to preserving their faith and legacy.
