Zhao Rui, a soldier of the People's Liberation Army, accidentally traveled to the Zhenguan period of the Tang Dynasty during an exercise. The Type 95 rifle and military watch he carried became special golden fingers - the rifle can absorb environmental energy and convert it into ammunition, and the watch can analyze the environment and enemy information. When he first arrived in Chang'an, his strange attire and equipment caused him to be misunderstood and hunted. Fortunately, he was able to gain a foothold with the help of scholar Li Xiuwen.
In order to survive and realize value, Zhao Rui joined the military camp. With the help of Golden Finger, his military concepts that transcended the times, and his excellent skills, he repeatedly performed extraordinary feats on the border battlefields and grew from an ordinary soldier to a powerful general. He not only has to face the swords and shadows on the battlefield, use his golden finger to analyze the enemy's situation and formulate tactics; he also has to deal with the open and secret fights in the court, using his golden finger to gain insight into people's hearts and resolve crises.
