Chang Geng intended to jump down directly. Before landing on the ground, he would use the Light Armor's leg protector on his feet to speed up and cushion the fall. Unexpectedly, Gu Yun had interfered. Momentarily in a state of shock, he stared at Gu Yun's face only inches away from his. His chest shook violently, and he could hardly sit still, grabbing hold of Gu Yun's cold iron guard on his wrist.

His gaze tore through the calmness on the surface, fiery as a living object, Gu Yun was angered: "What are you looking at!"

Chang Geng calmed down with difficulty, retracting his flaming eyes under his eyelids and coughing dryly: "It's time to cast the net."

Gu Yun pulled him to his chest then turned around and whistled. All Light Cavalry immediately gathered together and rushed toward the enemy's line like blankets. The Western army which had been shot heavily by the Black Eagles in the sky finally began to regroup with difficulty, Master Ja roared, "Open a path with Heavy Armors, tear a hole in the rear!"

There was no need to tear it open. The battle front of the Northern Camp chariots was arranged in a very feeble formation, withdrawing as soon as they made contact and letting the Western troops retreat.

Gu Yun made a gesture to Tan Hong Fei not far away. The Light Cavalry quietly withdrew, resembling a group of wild wolves that did not know what strategy was, running off as soon as they managed to take a bite, stopping just in time.

Otherwise, waiting until the Western troops came to and reacted, their meager Light Cavalry would only be nothing more than food for the enemy. Of course, when they did, the black whirlwind had blown away and disappeared into the darkness without a trace and could no longer be found.

On April 15th – Seventh Year of Long An, the Black Iron Camp attacked the Western troops at night in the west of Dong'an City.

On April 17th, the Western vanguard forces were led around in a circle by the nose by the Black Iron Camp for a few days. Finally unable to go on with this disturbance, they had sought reinforcement from their navy backup, then remained still in one place.

On April 23rd, the Western Army reinforcement arrived. Black Iron's Light Cavalry was forced to retreat. The Western Army continued their pursuit after gaining victory, rushing to Wuqing. They ended up being led into the trap to trigger the anti-air net by Gu Yun, more than half of the Western Eagle Armors were damaged, they were forced to retreat once again.

On April 26th, the Pope's condition had shown signs of improvement, he immediately returned to command the battles himself.

On April 29th, Wuqing fell.

On May 3rd, Daxing Prefecture was heavily shot by the Western Army.
