Ben is an international mercenary who lives in the hail of guns and bullets all day long. Because of a mission failure, he accidentally returned to China in 1938. He doesn't understand history, and he doesn't know how to hold the thigh of a great man to guide the country. He only fights at the forefront. He is called a war machine, because only in this way can he survive the flames of war and use the flames of war to kill the hatred in his heart. This book is dedicated to those martyrs who sacrificed for their country and nation.
