It turned out that the general of the northern Army had been assassinated by the killers of the Dark Moon Empire. Then, the Dark Moon Empire's Army had seized the opportunity to attack.
With the general's death, the northern Battlefront Army was thrown into chaos. The Dark Moon Empire took the opportunity to break into the northern Battlefront city and suffered heavy losses.
The remaining troops of the northern Battlefront Army intended to break through the siege, but they were caught up by the yinyue Army, which led to the battle just now.
Fortunately, they had the help of the ghost moon saber sect and the mystic essence sword sect's experts during this period of time. Otherwise, they would have been defeated long ago.
Coupled with the arrival of Lu Ming's Army, they were able to turn the tide and defeat the yinyue Army.
