Anti-Japanese Legend: Kill Without Pardon

This book is about a professional killer who inadvertently traveled back to the Anti-Japanese War during a mission. From then on, he picked up the gun in his hand and eliminated those who invaded his homeland. Although the male lead in this book is bloody, vicious, and has no feelings for the enemy, I feel that I hope to be such a person, because in this way I will not be easily hurt. . . . . .
