Li Guang, the Solitary General in Yinshan, Was Not Granted the Title of Marquis

In the fourth year of Yuanshou, there was a decisive battle in Mobei. Historical records record that the flying general Li Guang committed suicide in anger because he lost his way, leaving the eternal regret that "Li Guang could not be sealed". However, this is not a loss, but an earth-shattering cover-up. The protagonist Qin Feng was originally an abandoned son of the Li clan in Longxi and became a dead soldier of the border army. He was secretly promoted by Li Guang to lead a mysterious scout team called "Shadow Frontier". This team has no establishment, no food and salary, and its name cannot even appear in the battle report. Their mission is to carry out the dirtiest, most dangerous and deadly top-secret operations in the shadow of the Han-Hungarian War. From the narrow escape at Yanmen Pass to the secret intelligence battle in the Battle of Dragon City; from the thousands-mile run in the Hexi Corridor to the lone army's swan song in the Mobei wilderness. Qin Feng and his "Shadow Frontier" team shuttled through the gaps in history again and again, paving the way for the Han army with their blood, and taking the blame for Li Guang with their lives. While the rays of Wei Qing and Huo Qubing shine in the annals of history, Qin Feng and his brothers can only guard an unnamed stone monument at the foot of Yinshan Mountain. This is an epic about the "Unknown Man", telling a truth forgotten by official history: Li Guang did not teach Hu Ma to cross the Yin Mountains, and Qin Feng did not let Li Guang's regret come true.
