Shaanxi boy Wang Bo was raised by his grandmother since he was a child. He has a naughty and aggressive personality. He was expelled from junior high school for seriously injuring a classmate. After going south to work at the age of 16, he suddenly realized that he was determined to join the army. In 2013, he joined the "Steel Regiment" of the Lanzhou Military Region and met the master who changed his destiny - squad leader Zhang Zeye from Changde, Hunan. This capable soldier, who is only 165cm tall, forged Wang Bo from a "wild boy" into a "sharp shooter" with his all-around strength of "second in the regiment in pentathlon and second in the group army in one".
On the eve of the recruit assessment, news of grandma's death came. Wang Bo stood guard at night and kowtowed three times in the direction of his hometown. From then on, he buried his grief deep in his heart and did not speak a word for six years. He swept the competition arena with his "shadow shooting method", was selected into the top-secret "Shadow Force", and went to the beautiful country to perform espionage missions. Comrades Chen Hao and Lin Xue died one after another. Wang Bo was seriously injured and "resurrected", and finally fulfilled his promise to his grandmother with six military medals.
With the spiritual core of "protecting the family" and "not being afraid", the novel creates the image of Zhang Zeye, a Hunan soldier who is fiery and impatient but values love and justice, and shows Wang Bo's transformation from "serving his grandmother as a soldier" to "educating people for inheritance". After six years of silence and a huge promise, when Wang Bo finally stood in front of his grandmother's grave with a military medal, his personal destiny and his feelings for his family and country completed the most touching intersection.
