1895, Weihaiwei. Mr. Liu walked towards the artillery fire with his hunting knife on his shoulder, leaving his wife with an unborn child and a home to protect throughout his life.
Grandma Liu, who escaped alone into Changbai Mountain, passed down her Bajiquan and Sifang sword skills to her son and grandson. In 1931, the "September 18th" artillery fire shattered the tranquility of the Kanto land. Father Liu took 16-year-old Liu Jiadong into the customs and joined the 29th Army. Under the moonlight at Xifengkou, the father and son's swords were full of enemy blood, which also made them understand: one step back is home, and one step forward is country.
With his ancestral sword skills and sniper skills learned from the military, Liu Jiadong returned to the dense forests of Changbai Mountain. He did not vote for any political party. He only used his passion to pull up the "mountain protection team" and swore to protect the people and the pure land. Until 1943, a blood-covered Orion girl named Feng Ya broke into his world. Her father died tragically at the hands of her rival, and she escaped into the mountains alone to seek revenge.
From the artillery fire of Weihaiwei to the sword of the 29th Army; from the dense forest of Changbai Mountain to the oath of Yingzui Cliff. An ancestral hunting knife, the spirit of four generations of staunchness. They may not be remembered in history, but they have stood as the backbone of this country in the wind and snow.
