I Dominated with Guns in the Tang Dynasty

My soul traveled to the Tang Dynasty and became the orphan of a farmer who died tragically. I only had a trembling beautiful sister by my side. In order to take revenge, I took out the pistol hidden in my arms that would never leave my side in modern times. The Turkic bandit soldiers who slaughtered the whole village were all killed, with one shot in the head. No one could see clearly how I took action. From then on, wandering around the world with my sister, I got a nickname: "Take your life from the air, and Yama retreats." Until the Turks invaded the border again, I looked at the last three bullets and remained silent. The emperor insisted on sworn sworn sworn relationship with me and asked me to return to the battlefield to fight the enemy. I smiled and clasped my fists: "The gun is out of ammunition, but our territory of the Tang Dynasty is protected by the gods!"
