Even the Saint Origin Army and the Ancient Land Army could run into problems when rotating troops, let alone the Pearl River Army. Only the Main Force Army, composed of natives of Two Worlds Mountain, could carry out a seamless rotation without affecting the battle in the slightest.
Fang Yun had anticipated this situation long ago. He set down the book in his hands and watched the front closely.
The previous seventy thousand troops had already withdrawn from the wall, and the new seventy thousand were attacking with all their strength. Yet the Demon Barbarians' assault was so fierce that these soldiers, fighting at Two Worlds Mountain for the first time, had already begun to lose their composure. Their three-stage volleys became chaotic. The soldiers at the very front were so nervous that their bodies went rigid, and even the officers panicked, no longer able to direct their War-Poem Soldiers calmly in battle.
After learning to work together, the previous Hanlin Academicians and Metropolitan Graduates had been able to employ powerful Wolf Pack Tactics, concentrating their numbers against a single foe to swiftly kill Demon Marquises and Barbarian Marquises. Now, however, the new Metropolitan Graduate generals frequently made mistakes. Two Demon Marquises were already standing on the wall. Had they not been wary of Zhang Qingfeng and Fang Yun, they would have leaped into the archers' ranks and begun a slaughter long ago.
The distant Grand Academicians looked disappointed, and several Grand Academicians of the School of War discussed the situation in low voices.
"The Pearl River Army's many-against-one attacks were highly effective earlier. I thought it was the power of a military art, but now it seems this isn't an art that can be used directly. Those men merely became adept at coordinated attacks after learning to work together."
