At the same time that the Daimon tribe was defeated and Ma Jiu at the southern end had a little joy of victory, the thousands of miles of mountains and grasslands in the north also experienced the battle of life and death. At the same time, the four generals Ye Ling, Ye Feng, An Miao, and Mo Fei marched west and then north from their respective mountains, and Yeats led nearly 6,000 men from Mount Xie Ning to the Wushan Mountains in the northwest. Five days later, Yeats reached the Osan Mountains, and at the same time the four chieftains from the west also rushed west. But to everyone's surprise, the dark horse of the Evil Spirit Emperor killed the steppe tribe in the shortest time that Yeats expected at lightning speed. The steppe people could not resist the offensive without the slightest delay and fled to the south of the Wushan Mountain Range, if the Evil Spirit Emperor went all the way south to chase the remaining steppe people, not only would they kill all the grassland herdsmen, but they would also turn into the Wushan Mountains from the west and just meet Yeats's soldiers and horses, at that time Yeats would be unexpected and caught off guard, he must not be the opponent of the Evil Spirit Emperor, after the Evil Spirit Emperor defeated Yeats, and then came out of the Wushan Mountain Range to meet Ye Ling Ye Feng who came to intercept them, they came to a final end, then the north would completely fall into the hands of the Evil Spirit Emperor. Yeats also thought of such a sudden change, but the probability was very small, because he ignored that the Evil Spirit Emperor was once the overlord of the grassland, and even after a hundred years, he knew that Yeats could not expect that the dangerous road from the Xialing Mountains to the center of the prairie could avoid the mountains through the barren land. But what was even more unexpected was that the Evil Spirit Emperor did not do this.

When the sun rose, the innocent grassland herdsmen were killed by the Evil Spirit Emperor, and the nomads on horseback could never resist this group of dark horse devils. Successive white tents became red-and-white slaughterhouses, and the herdsmen's leaders decisively ordered the retreat south to abandon the Baylor steppe. The Evil Spirit Emperor quickly finished killing the grassland men who stayed behind and delayed, and when the thousands of dark horse cavalry were preparing to come to the battle like chasing prey with great interest, the Evil Spirit Emperor looked at the grassland people who fled south but hesitated. He seemed to see the scene of being chased by the people in front of him a hundred years ago, the desolation and grief were indescribable, which should have made the Evil Spirit Emperor hate the grassland people even more, but that kind of down-and-out back aroused the pity in the heart of the Evil Spirit Emperor, who had long since died, of course, he was not to those grassland people who fled in the wilderness, but to himself and his subordinates, who were half-human and half-ghost. He actually ordered the whole army to rest for the time being and take a good look at the "homeland" they fought in the past, the Evil Spirit Emperor knew that after a while, if he chased after him, he would let go of a lot of "prey", he didn't know if it was right or wrong for them to achieve the blueprint for fighting the world, but he still did that, and neither the Evil Demon Emperor nor the Evil Flame Emperor would make such a decision. The Evil Spirit Emperor's eyes were still full of the black blood flame of revenge and desire, and he laughed in his heart that the dark purgatory, which was worse than death for a hundred years, had not completely burned the only remaining kindness and sympathy in his heart, even for his own people.

After a while, an old cavalryman who had been following the Evil Spirit Emperor said, "Spirit Emperor, we should leave the grassland and go south. After looking around, the Evil Spirit Emperor immediately ordered the whole army to go south to chase the steppe people and then kill the Aran people, so the four thousand black horse cavalry marched on the green grassland to the Wushan Mountain Range to the south. However, due to the momentary hesitation and so-called "sympathy" of the Evil Spirit Emperor, his attack happened to be in line with Yeats's strategic plan.

Yeats, after receiving the down-and-out steppe people in the Osan Mountains, ordered his people to prepare for battle immediately, and he realized that he had misestimated the timing, but after several hours there were still no black horse cavalry. Yeats looked at the large open field in front of him, and the feeling of strangeness in his heart became even stronger, and he was a little anxious, wondering why the Evil Spirit Emperor didn't chase after them.

After another two hours, the deafening sound of the black horses began to run from the north, and Yeats did not dare to think too much about it and immediately ordered the whole army to prepare for battle. When the black horse cavalry came to the foot of the Osan Mountain Range, they rushed forward without fear, and even if they felt the danger of the mountain in front of them, they would not stop their march, because they had no sight of everything.

Smoke began to rise from the sky north of Osan Mountain, and no vegetation grew in the pitch-black Osan Mountains, and the steep mountain walls resembled a dull rusty knife. When the black horse cavalry was about to step on the low-lying path below, hundreds of boulders fell from the sky, and the black horse cavalry were smashed and turned on their backs, and rows of arrow carts suddenly erected on the cliff, which was a weapon that could fire long arrows, and the lethality of penetration was ten times greater than that of bows and arrows. The rain of arrows and the huge stones falling from the sky made the dark horse cavalry of the Evil Spirit Emperor crush in an instant, and the Arlan people on both sides rushed down from the trail and the cliff with their swords shouting. The black horse cavalry who had not recovered from the fright fell down in an instant, the Evil Spirit Emperor saw that the situation was not good, and hurriedly drove his horse to flee to the west, at this time Ye Ling Ye Feng killed from the west mountain range, An Miao and Mo Fei rushed over from the northwest, although the black horse cavalry was one enemy and ten, but it seemed that the general trend had gone, the Evil Spirit Emperor was always outnumbered, and after two hours, more than 4,000 black horse cavalry were killed by the Yalan people There were less than three thousand left. But they had lost their advantage, like lambs in the fence to be slaughtered at any time, the black horse cavalry had to return to the north, Yeats ordered the whole army to pursue, the evil spirit emperor did not run long before he was besieged by the raging fire in the north, the old cavalry advised him that the flames could penetrate the heart to save his life and run northeast. The Evil Spirit Emperor knew that at the end of the northeast was a dead forest that no one had entered, but in order to escape for his life, Yeats sent some of them to the northern grasslands to extinguish the fire, and all the other Arans chased them all the way without giving them a chance to breathe.

After tens of thousands of Yalan people went back and forth for several days and nights, they finally forced the Evil Spirit Emperor into the dense forest that no bird dared to fly into. The Evil Spirit Emperor did not dare to turn back and fight back, because the Arans would not separate the gap that they had broken for them, and the Arans were more familiar with the terrain here, so they had no way to break away from the escape route set for them by Yeats. The Evil Spirit Emperor crossed the abyss and a field of sparse green grass and went straight into the dense forest where there was no way to retreat.

The forest, known as the Valley of Desperation, is home to towering trees, thousands of alien animals, and staggering black monsters deep in the forest. When the Evil Spirit Emperor entered with the remaining black horse cavalry, they were surrounded by moving trunks of large trees and man-eating grass, and they would be trapped in this dead forest forever. After being trapped, the Evil Spirit Emperor began to regret his inexplicable actions on the grassland, but it was already too late for him. He would be imprisoned here for an infinite time with his remaining nearly 3,000 black horse cavalry, knowing that all the blame would be his, but what he would never have imagined was that a thousand years later it would be his only mercy from the depths of his soul that would redeem them.

When the crisis in the north is resolved, the Arlan people will be proud of their bravery and perseverance, and the steppe people will be grateful to them with tears in their eyes. However, at this time, Yeats did not have any joy, he gathered all the tribal leaders and solemnly told everyone: "The war is not over, the real disaster is not in the north, but in the south, if we want to survive forever, we must go south to help the Daemon defeat those demons." ”

At this time, the south had turned into a hell on earth, and after the Evil Flame Emperor turned the river valley plain into a scorched land, he led his troops to the dense forest to find the escaped Damons. Ao Han led his people across the Shengya River to the west bank, and the Evil Flame Emperor passed through the dense forest and prepared to cross the river to annihilate the remaining Daimon tribe in one fell swoop, just at this time the Evil Demon Emperor's dark horse cavalry came to report that they had suffered a great defeat in the Black Cong Mountains. The Evil Flame Emperor was so shocked that he had to stay behind and garrison some of his men on the east bank of the Shengya River to surround the Daimon tribe, and then take most of the remaining dark horse cavalry to help his eldest brother. At the same time, the northern Alans regrouped and prepared to march south towards the valley plains
