Chu Zheng hated two things most in his life: traitors and Japanese.
In the battle of Taierzhuang, he led his wolf soldiers to cut off hundreds of enemy heads, but was sentenced to death by a "collaborating with the enemy" message. On the way to escort, Liu Huozui, a defeated Sichuan soldier, stuffed him with half a pack of cigarettes, with an escape route drawn on the back of the cigarette paper. He escaped and fled into the mountains, only to find someone waiting for him.
A woman, half of her face removed by bullets, was his aunt who had been dead for ten years. She told him three things: Your father is not dead. Your father is imprisoned in Black Dragon Mountain. Your father's number is zero.
Zero is neither a living person nor a dead person. It was the Japanese army that spent three years pumping medicine into his veins, making him forget everything except half of the mine map. Whoever can get the complete map can cut off the lifeblood of the entire East China battlefield.
Chu Zheng led three hundred old wolf soldiers with scars all over their bodies, and climbed up the Black Dragon Mountain in the dark. He betrayed his emaciated father, lost his aunt's life, and found that the person closest to him had a banknote worth enough to buy a city hidden in his pocket.
The mole is behind you. The devil is right in front of you. The mineral map was only contained in the few words his father occasionally said when he was awake.
"Dad, think about it again."
"There is water in the mountains, and there are holes beside the water. In the holes..."
"What's in the cave?!"
"I don't remember."
Three hundred knives, a zero number, and half a broken picture. In this battle, he wanted to get his father's memory back from the Japs' minds.
