The blades inside the Wind Slasher in Gu Yun's hand had not been unleashed yet; it still had the shape of a smooth and black iron rod. But the sharp tip has already plunged into the shoulder of the Heavy Armor with incomparable precision. The mechanism on the shoulder of the Heavy Armor was suddenly cut off. The barbarian's iron arm made a piercing noise, then deadlocked: the long sword that came slashing down was hanging in the air.

At this time, the distance between the blade and Gu Yun's forehead was less than three inches.

And he did not even blink.

Gu Yun pressed on the warhorse's belly with his heel. It let out a loud neigh and jumped up. The hand that was hugging Chang Geng's waist slowly moved up, covering the boy's eyes. The Wind Slasher's blades surged out as the horse charged forward. Steam spurted out violently, creating a small explosive noise, and the three-foot-long rotating blade was unsheathed, cutting the barbarian man into pieces from the shoulder up.

A damp, warm steam sprayed on Chang Geng's neck. He was puzzled for a brief moment until he smelled blood.

The scent of bitter medicine that seemed to absorb into Gu Yun's body was buried deep under the Iron Suit. Unable to detect it, Chang Geng felt as if the man sitting behind him right now was a stranger.

His little yifu seemed to have never existed.

The barbarians had mustered up all their strength, gathered all the Heavy Armors they had in possession to launch a surprise attack on Yanhui Town; it could even be said that they had risked their old lives for this. The Heavy Armor forces that even Great Liang struggled to support, imagine what this concept would be like to the Man's Eighteen Tribes?

Perhaps even 'wringing out the grease' would still be far from enough, they must scrape down to the bone and marrow thrice.

Naturally, as their race was one that grew up sharing the same nest with wolves, they were well-versed in the arts of combat. Considering their long-planning and Heavy Armored forces, as expected, they should be invincible.

Unfortunately, they clashed against the Black Iron Camp.

The Black Eagle took back control of the Giant Kite, and Dark Armors captured the barbarian prince alive. Under Gu Yun’s acquiescence, they had slain all the remaining fallen forces in the city. The sun had not gone down, and yet, the battle was already over.

Still not done, after Gu Yun finished handling foreign enemies, he immediately turned his forces over to his own side as fast as lightning. As the name of the renowned Black Iron Camp was still striking fear in the hearts of many, he had arrested all the military personnel of Yanhui Town and Changyang Gate from big to small: there were more than sixty people in total from the first line of the Northern border.
