Shen Yan, the ace captain of the Wolf Fang Special Operations, died heroically for his country and his soul passed through the body of the cowardly grandson of the Shen family in the Republic of China in 1935. At that time, the Japanese invaders were around and troubled times were approaching. The evil slaves of the family deceived the master. He used his iron-blooded special warfare skills to gain power, control the family property and hoard war supplies, subdue the loyal and brave team, travel across the sea of espionage and the battlefield, kill the invaders and protect the country in blood. He transformed from a down-and-out young master into a powerful anti-Japanese war god, and finally survived.
