As for Ma Lan, who was in the camp of Downhill Slope, who was constantly watching the movement of the western camp, when she saw the movement of the western camp, she knew that it might be because she noticed that there was a problem with the eastern camp. Therefore, it was time for their northeast troop to come out.
Just as the western camp was about to send troops to the eastern camp, Ma Lan suddenly led several thousand troops and horses of the Northeast Army out of the garrison camp, rushing towards the left camp which had no troops, intending to attack from the east and attack from the west.
