As night fell, the sky was filled with stars for the first time in months. Everyone was glad that Heaven had given a good omen at this time, and that night all the warriors who were going to leave tomorrow morning slept late, and they were watching the sky with their eyes that were both dead and alive.

Before leaving, Ao Han hugged Qiu Li in the starlight and said to her: "Tomorrow I will lead the soldiers to set off to fight the last battle, wait for me to come back, okay." I should arrange for you to take care of you, and the people who should take care of you have been arranged, and after I come back, I will never go out again to take care of you every day, and you will get better soon. Qiu Li smiled, laughing so weakly and far-fetched. She said, "Well, I know you can come back and I can wait for you, but I'm afraid... I'm afraid you won't be able to wait for me. With that, she coughed heavily. After Ao Han heard what she said, his heart was as uncomfortable as a knife, he hugged Qiu Li hard, his tone was very firm, but his eyes were wandering, and said, "No, no, you will definitely be fine." Qiu Li didn't speak again, she just wanted to snuggle up in his arms and lie down in his arms while she could still be together.

Early the next morning, about 10,000 warriors of the Daemon and Alam tribes set out on a path of revenge. They had to cross the Shengya River, then through the dense forest, then through the valley plains and the Yujiang River, and then through the southern mountains to reach the Black Cong Mountains. When passing through the river valley plain, Ao Han and the clan warriors gritted their teeth angrily when they saw the scene in front of them, and the hatred for the black horse cavalry suddenly penetrated into their bones, and everyone clenched the blades in their hands and ran towards the southeast without too much nostalgia.

And when they passed through the dense forest and reached the river valley plain, more than 2,000 black horse cavalry led by the Evil Flame Emperor had already reached the Heicong Mountains. The Evil Flame Emperor didn't dare to intrude, because he didn't know the location of the pterodactyl, there were many twists and turns in the Black Cong Mountains, ravines and uneven mountain roads, and there were too many dark and damp mountains and no sunlight, so it was very difficult to travel in the Black Cong Mountains. The first thing the Evil Flame Emperor had to do was to follow the rescuers sent by the Demon Emperor to find the location where the Evil Emperor was hiding, and then the two armies would make peace and discuss the route of attack. Ma Jiu sent eighteen strong warriors of the savage tribe to drive the pterodactyl to observe the movements of the black horse cavalry in the mountains, and the pterodactyl guards found them when the Evil Flame Emperor first arrived at the boundary of the Black Cong Mountain, but the role of the pterosaur at night was only to reconnoiter and not attack.

After Ma Jiu learned of the arrival of reinforcements from the Black Horse Cavalry, he quickly summoned the major savage chiefs to discuss countermeasures with the savage warriors. The Great Chief of the Savage Clan said: "The two dark horse cavalry will definitely not rush to attack again, they have already learned the power of the Pterodactyl, and they will try to strategically bypass the Pterodactyl to attack our rear." Ma Jiu looked at the ground ring model map of the Heicong Mountains and was silent for a long time, and then said: "That's right, after the meeting, they will survey the terrain and then find a suitable route for their attack." And now all we're looking for is to see which route will make the Pterodactyl's attack the most uncomfortable and their attack the smoothest. Ma Jiu and the others were staring at the circular map of the Black Cong Mountains that zigzagged like a maze, and it was very difficult to guess the offensive route of the Black Horse Cavalry on such a map, but Ma Jiu had to find that route, only then could he dispatch troops in advance to assist the air attack of the Pterodactyls, because the Eighteen Pterodactyls alone could not stop the Black Horse Cavalry.

Since the pterosaurs didn't interfere too much, the Evil Flame Emperor quickly found the Evil Demon Emperor hidden in the third mountain of the Black Cong Mountain by taking advantage of the night, and all the remaining black horse cavalry finally met. In such a dark but familiar cave, finding a suitable route for the march was not only difficult for Ma Jiu, but also difficult for the dark horse cavalry. They didn't dare to go out during the day, they could only rely on the cover of night in the middle of the night to avoid the vision of the pterodactyl, the Evil Demon Emperor and the Evil Flame Emperor personally led a group of dark horse cavalry to circle around the mountains and rocks at midnight in the major mountain ranges, the terrain of the Black Cong Mountain may be the most difficult war road they have encountered in their lives, how to safely avoid the pterodactyl through this layer of mountains to Ma Jiu's nest has become a common problem for both sides. And Ao Han and Yeats, who are still on the rescue road, are also thinking about this problem all the time, for them, this problem needs to be solved even more than the black horse cavalry, because if they break into the Black Cong Mountains without direction, they are likely to encounter the black horse cavalry alone, and at that time, not only will they not help Ma Jiu, but they will also add to the chaos.

Four days later, Ma Jiu still hadn't guessed the final movement of the Black Horse Cavalry, and he could only fill the more than thirty steep roads leading to his lair with sentinels, allowing the pterosaurs to scout in the air all day and all night, while the Daimon and the Arlan had also rushed to the boundary of the Black Bush Mountain. On the evening of the fifth day, a strong wind suddenly blew in the black bush mountains, and the dry yellow grass and fallen leaves were blown in all directions. Ao Han, Yeats, and other generals were looking at the strategic map of Black Cong Mountain, and Yeats said with some irritation: "We can't spend any more time in front of this mountain, according to the speed of the black horse cavalry, if the route is cleared, it will only take half a day from the launch of the attack to the end of the battle." Let's go in first while it's dark, they'll leave their footprints. Yeats's military advisor said, "No, if you can't find a route to the army, you'd rather go into the mountains at dawn than at dark." If we march in the dark, if we encounter a black horse cavalry, we will not be able to see anything in the black rumbling, and we will suffer a great loss just by sound. ”

After listening to their conversation, Ao Han suddenly looked up at Yeats's military advisor and looked nervous, Yeats, the military advisor and the others were startled by his sudden reaction, and Ao Han said to himself, "It's dark...... What if you can't see and you can't hear? I know where they're going to attack. Everyone looked at Ao Han blankly, and Ao Han pointed to a valley mouth on the map and said, "I will definitely go here." Everyone unanimously set their eyes on that position, "Wind Chime Valley Mouth" Yeats said with some puzzlement.

Ao Han excitedly explained: "Yes, Wind Chime Taniguchi. This is the only passage they can have the opportunity to enter Ma Jiu's territory, the black horse cavalry must march when it is dark wherever they go, and they are suitable for fighting savages in the dark, but the pterodactyl will have reduced eyesight when it is dark, and the pterodactyl can only judge the position by the black horse's hooves and horse neighing. Nowadays, there are often strong winds in the Black Cong Mountain these days, especially at night, the mouth of the wind chime valley is like a wind organ, and when the wind blows, it will make a long sound, which is the best passage to hide people's ears and eyes. Yeats looked at the map happily and said, "In that case, can we have a two-sided attack?" ”

Ao Han immediately responded: "Yes, a flank from behind." Once they moved in this direction, Ma Jiu should be able to guess their movements. At that time, they will definitely engage at the mouth of the Wind Chime Valley, and the Pterodactyls will greatly reduce their combat ability in that situation, and we need to cooperate with Ma Jiu to attack from the rear, and fight in front and back to fight until dawn, and as soon as the sun comes out, they have no way to escape, then we will win. "The wind outside was still blowing with heat, and the night was getting darker, and the sky was pitch black without a trace of light.

And the dark horse cavalry on the other side was indeed as Ao Han guessed. The Demon Emperor and the Evil Flame Emperor arrived at the mouth of the Wind Chime Valley at dark on the second day of Ao Han's arrival, and the sound of the wind came through the mountain stone hole with a piercing sound of contention, and the two leaders were both frightened and surprised by this natural sound, and they finally found an excellent passage to Ma Jiu's lair.

When it got dark one day, the Evil Demon Emperor and the Evil Flame Emperor led more than 5,000 black horse cavalry to leave the Third Black Cong Mountain and march towards the mouth of the Wind Chime Valley in four ways.

The men of the Pterodactyl Guard reported to Ma Jiu, who was in the rear: "The Black Horse Cavalry has left the third Black Cong Mountain in four ways, and they are heading for the northeast bend in two directions, and the other two are heading south. Ma Jiu stared at their marching route on the map, he couldn't figure out what kind of medicine was sold in the gourd of the black horse cavalry, and the leader of the Pterodactyl Guard said: "At this time, it is better to take the initiative to attack and destroy them one by one." Ma Jiu said anxiously: "No, it's dark and dangerous, their whereabouts are secretive, if the pterodactyls are all separated, once they will attack a place with all their strength, we will be caught off guard." Listen to my orders and keep tracking, and come back to me as soon as there is any change in direction. After receiving the order, the Pterodactyl Guard flew into the sky that was already extremely dark at this time.

Three hours later, the two dark horse cavalry marching southward began to turn around and move to the northeast, while the two armies that had been heading northeast gradually moved closer to the southeast, and they met in one direction. The darkness gave the Pterodactyl Guards a big headache, and many of the soldiers stationed in Heicong Mountain reported to Ma Jiu that they saw the shadow of the black horse cavalry, and Ma Jiu's mind was blindfolded for a while, and according to what they said, there were at least 20,000 black horse cavalry. Ma Jiu's eyes widened, and he shouted nervously: "It's not good, this is confusing our vision, they must be meeting in the same place." Where is the position of the black horse cavalry in the end?" The soldiers of the two teams of pterosaur guards respectively said the two directions of the black horse cavalry, and the stronger and stronger wind outside pierced Ma Jiu's head like a long thorn, he slapped the table and shouted: "The big thing is not good, immediately ordered all the guards and soldiers in the various mountain ranges to go to the mouth of the wind chime valley to guard, they will pass through the mouth of the wind bell valley tonight, and they must hold it, otherwise we will be all finished." After receiving the order, the savage tribe immediately set out, and the eighteen-winged dragon lined up in a herringbone shape and flew across the sky and quickly flew towards the mouth of the wind chime valley.
