Yan Zhaoran was originally an important minister in the court, but because of his outspoken words, he offended Long Yan and was demoted to a bitter and cold place on the border. When the border was closed in the snow at night, he lit the beacon fire in the north and asked for battle with a blood letter, which actually triggered the old border treaty that had been dormant for hundreds of years. Wei Shubai, a lonely and brave general who was exiled by the imperial court in the past, appeared in the snow and met his eyes. Without saying a word, his swords were at each other's throat. The two were once colleagues, but now they are strangers. But when foreign enemies invade the country and the imperial power plots against them, these two people who have been forgotten by the world have become the only pawns that can save the common people. The war is still going out, and the country is in turmoil. Who is the true loyal minister? Who is holding the child in the dark?
