Starting from the 933rd year of Black Iron Calendar, after Zhang Tie destroyed the three major demon camps and killed four sage-level demon knights, the overall situation facing Taixia Country had been immediately reversed in an overwhelming manner like surging rivers. As a result, the armies in Taixia Country which were always in defense started to attack. They broke into the territory under the control of demons and started to recover their lost territory. Only after more than half a year, Taixia forces had already regained Ganzhou Province, Liangzhou Province, Yuzhou Province and Anzhou Province which were once occupied and managed by massive demon forces in order to threaten Lingzhou Province, Lizhou Province and humans' defense line at Tongguan Pass.
