During a military exercise, People’s Liberation Army soldier Zhao Rui accidentally transmigrates to the Tang Dynasty, during the Zhenguan era. The Type 95 rifle and military watch he carries become his special golden finger: the rifle can absorb energy from its surroundings and convert it into ammunition, while the watch can analyze the environment and provide information on enemy forces. When he first arrives in Chang’an, his strange clothes and equipment lead to suspicion and pursuit. Fortunately, the scholar Li Xiuwen helps him find his footing.
To survive and make something of himself, Zhao Rui joins the army. With the help of his golden finger, military ideas far ahead of their time, and formidable skills, he repeatedly distinguishes himself on the frontier battlefield, rising from an ordinary soldier to a general feared across the land. He must face the clash of blades on the battlefield, using his golden finger to assess the enemy and plan his tactics, while also navigating the open and covert struggles at court, relying on his golden finger to read people and defuse crises.
