The ice field post was windy and snowy, and Li Xiao guarded the border alone for seven years, but was accused of being a traitor after a raid. The evidence points to him having an affair with the enemy, and even his most trusted comrade-in-arms Feng Zhuo points a gun at his chest. That night, fire exploded and the outpost collapsed. The truth was still unknown and the hunt was on. Li Xiao didn't say a word, and only used his flesh and blood to block Feng Zhuo's fatal blow; but when Feng Zhuo was about to die, he found an old badge with his childhood name engraved on it from his bloody fingers - it turned out that it was never him who betrayed him.
