The formation light rose from the city wall of Earth City, immediately followed by a dazzling red heavy arrow flying out from the city head, shooting towards the Qingming Army Formation three miles away from the city wall.
The heavy arrow traced a clear trajectory in the air, finally landing less than a hundred zhang from the infantry guns.
This was a marker arrow used by the Liao Clan for measuring range. A single order from the Liao army commander on the city wall brightened the formation light even further, and another arrow was shot, flying much further with the formation's support, directly into the center of Wei Yuan's military formation.
A sword light rose from within the army formation, intercepting the arrow. However, the next moment, having measured the range, the Liao defenders unleashed a volley of arrows, a rain of arrows whistling towards Wei Yuan's army formation.
