This blade that had been tempered must be sharpened with the enemy's blood.

Gu Yun could neither see nor hear clearly. He could only judge the distance of the exchange of fire by the tremors under his feet. He was not even in the frontline of the battle. However, he did not panic. The Black Eagle was shocked to find that the whole defense of Jiangbei was in his mind, where the strong or weak points were, where the enemy would choose to make breakthroughs and so on...his speculations were entirely spot on.

Now that the command of the front line had been handed over to Chang Geng, Gu Yun simply and generously gave him unreserved overall trust, without making a single instruction of his own. The three armed forces in Jiangbei were all for Chang Geng to command.

Gu Yun generally monitored the overall situation of the war, while calculating the distribution of Ziliujin and ammunition everywhere. At the same time, he was holding the red label letter from the Northern Frontier, his efforts had been divided into two routes, landing in the two ongoing battles North and South of the whole territory of Great Liang.

The unexpected deployment of the Westerners this time was for the sake of the barbarians. Ultimately, it was for the sake of negotiating interests. If the northern battlefield could withstand, the Westerners would simply be clowns jumping about, but if the northern battlefield failed——

Jiangbei was bombarded with artillery in the haze, while the Northern Frontier was boiling endlessly in the silver-coated plains.

Jia Lai had used suicide soldiers and his son to open the way, setting off Ziliujin, then a large number of Northern Barbarian warriors rushed out like mad, as if they wanted to perish altogether with their enemy.

Shen Yi made a decisive choice and withdrew the Black Iron Camp, which had already penetrated the enemy's hinterland by more than ten miles, and galloped like mad on the snow.

The Black Iron Camp's quality need not be mentioned, running at incredible speed, the barbarians became only a single thin line in the distance.

The barbarians changed their faces faster than turning over the pages of a book. The garrison in the Northern Frontier had become accustomed to this style of their good neighbor. With a signal from the Black Iron Camp, they were immediately mobilized.

He Rong Hui and Shen Yi had been working together for many years. Needless to say, the reinforcements kept up with him quickly and cut across the long front.

Who knew that Jia Lai had used everything he had, when the cavalry opened, several Heavy Chariots which they had not been willing to use for many years were revealed. Hundreds of Heavy Armor's poured out, using fire power to push a big net, colliding with the black whirlwind that was the Black Iron Camp. The frontline was momentarily in a stalemate.
