The Red Kite carrying the Emperor moved towards the city gate, more than one hundred Imperial Guards and a hundred officials marched along. On the path from the Qi Yuan Tower to the gate, refugees and local people who fled to the capital continuously rushed out from both sides, gathering together like rivers pouring into the vast sea.

At this time, the city gate finally could no longer be sustained. The anti-air net had quieted. The rockets had been used to the bottom.

Gu Yun shouted an order for people to open the city gate.

The Black Iron Camp’s Heavy Armors that had been in waiting for a long time surged out of the gate. Gu Yun made a gesture with his hand towards the wounded soldiers on the city wall.

The city gate slowly closed behind the Heavy Armors’ formation.

Gu Yun pulled down his iron protective mask, all the Heavy Armors behind him followed his action.

In the next moment, all Heavy Armors moved.

The ruined walls rumbled with the unbelievable sound of footsteps; a group of black iron armors soaked in the thick snow-white steam that could not disperse in the wind headed towards the enemy's sea of artillery fire, like water against the sea current.

The first batch of Heavy Armors resembled a blade that could block everything, sweeping through like a fierce whirlwind, pushing directly into the enemy's line. Heads, bodies, and limbs were exploding into pieces, but strong fire could not burn black iron. As long as the golden box itself did not burst, most of the corpses could still remain upright. The corpses of the officers and soldiers inside were dead, but the mechanical gears were still rotating, as if their souls had not yet dissipated, continuing to rush forward.

When it became difficult to carry on, there would be someone following behind to open the golden box at the back of the black armor to ignite the lead hidden in it.

The officers and men under the iron masks did not differentiate from each other, thousands were united as one. Seasoned commanders were the same as the newly recruited little soldiers in the Northern Camp. They either slayed the enemy's heads with a Wind Slasher in their hands, were under the enemy's artillery, or exploded into a purple firework anonymously.

Li Feng stood on the Red Kite with his arms crossed. He suddenly said to Tan Hong Fei who was ordered to stand on the side, "Where is A Min?"

Tan Hong Fei was suddenly called, he was stunned for a moment then responded, "His Highness Jun Wang has gone up to the city wall."
