The Northern Alliance army was caught off guard and did not have time to mobilize troops to block the onslaught of Liu Rang's cavalry. Seeing that the sneak attack troops had been killed in front of him, Zhao Dongguo's personal soldiers wanted to escape with him. Zhao Dongguo shook off his own soldiers, smashed his helmet on the ground and shouted: "As soon as the commander retreats, the whole army will collapse immediately." Lao Tzu would rather let people die than be a shameless deserter. Inspired by him, the soldiers marched forward one after another, and soon killed Liu Rang's war horse, which was at the forefront. Liu Rang fell off his horse and was trampled by countless cavalry behind him, and died with a whimper.

However, the number of Zhao Dongguo's personal soldiers was too small to resist the fierce impact of Liu Rang's cavalry, and they were soon all killed one by one. The hurricane-like Black Cloud City cavalry swept by, not only hacking Zhao Dongguo to death with a knife, but also cutting down his handsome banner. The army of the Northern Alliance saw that the commander was eliminated, the flag was cut down, and the morale collapsed. The originally stalemate of the front collapsed in an instant, and a large number of officers and soldiers dropped their weapons, knelt on the ground, and raised their hands in surrender. Others scattered and fled, completely crushed.

Lin Yi ordered his subordinates to chase down the deserters and clean up the battlefield, while he personally led a team to rush into Fuyang County to rescue Zhao Hui.

News of the collapse outside the city soon reached the city. At this time, although there were less than a thousand people left in Zhao Qinghai's department, the officers and soldiers of the Northern Alliance saw that the dragons on their side were leaderless, and it was impossible to organize a formation to block the fierce offensive of the main force of the Qinglong Kingdom. They thought that it was no longer necessary to continue the battle, and the soldiers were discouraged, and the officers could no longer stop the spread of the rout, so they had to flee or surrender as the soldiers laid down their arms.

Under the pressure of the cavalry-led team leading by Lin Yi, the army of the Northern Alliance, which was not very large in the city, was quickly pacified and disintegrated. Lin Xiaoshuang easily rescued Zhao Hui and the other remnants.

By the time this unusually fierce battle ended, it was past noon. The soldiers of Black Cloud City were not only exhausted, but also hungry and too late to eat. However, Luo Ming did not let them rest on the spot. He personally took Lin Yi and other generals to gallop around on the battlefield, encouraging the soldiers to say: "We have created a great miracle, but the war is not over yet." The army of the Mahuaishan Kingdom is frantically besieging the castle defense. Our fathers and fellow villagers are under serious threat. I know that everyone is working very hard, but please be sure to do it. Only by defeating the enemy forces attacking the castle's defenses can the war be finally won. This king will starve with you and charge into battle together, please follow this king and create this last miracle together! Our descendants of Black Cloud City will always sing about our immortal exploits today, and will always be proud of the efforts we have made today!"

The battle to protect the castle's defenses has been raging. The fighting here seems to be more intense than on other battlefields, and the two sides have been fighting large-scale offensive and defensive battles since the beginning of the war. Despite the heavy casualties, the officers and men on both sides showed a spirit of undaunted death, and many seemed to fight tirelessly until the last breath and the last drop of blood.

Although Luo Zhen, the main general of the Ma Huaishan Kingdom, is arrogant, he knows very well in his heart: he has led so many men and horses, and he has also brought elite war elephant troops with strong combat effectiveness, if he can't even take a small Mingyang Fort defense line, what cowhide will there be to brag about in the future? So his heart is more anxious than anyone else, he can't take the castle defense line, he can't even eat, he can't sleep.

But the castle's defenses were much stronger than he had imagined. Not only did it make a double-layer city wall, which made it difficult for the attackers, but the equipment of the defending troops of Black Cloud City was surprisingly good, and the lethality of the hard crossbow was very amazing, and it could still penetrate the ordinary armor and even iron shields of the soldiers of the Mahuaishan Kingdom from two hundred meters away. Within three hours of the attack, they had completely captured the first wall, but they also paid tens of thousands of casualties. In particular, the elite war elephant troops suffered heavy losses. The "canine barb arrows" used by the enemy to deal with elephants made the injured elephants extremely frightened, and even if they were cured, they were reluctant to go to the battlefield again and participate in the attack. The elephants, which were not injured, were also affected by the panic, and not only did they not want to go to battle, but they also lost their temper when they were pressed. In desperation, Luo Zhen ordered the mahout to use a red-hot iron to intimidate the elephant herd into attacking, and finally subdued the frightened elephants.

It was much more difficult to conquer the second wall than the first. Not only did the defenders fight to the death, but they often fought back against the first wall through secret passages. The open space between the two walls was littered with the carcasses of men, horses, and elephants, and the scene became slippery due to the blood and internal organs, causing great difficulties for the officers and men of the attacking side. Not only do people often fall, but it is also very difficult to erect ladders.

As the defender, Jeon Zhonghan is under more pressure. He had already suffered more than half of the casualties on the first day of the battle, and had to pull all the reserves led by Liang Xu into the battlefield. This included 40,000 border guards guarding the castle and 10,000 on the second line of the Flying Tigers. Although this group of people helped him stabilize the battle line very effectively, their losses, mainly the losses of the Qinglong Flying Tigers, made Quan Zhonghan and Liang Xu heartbroken. Because these players are all talents who can enter the first-line team of the Flying Tigers, they are truly one in a million. Everyone knows that it is not easy to be able to enter the Flying Tigers. Assuming that the Flying Tigers expand their establishment in the future, Black Cloud City will really be able to create a myth of invincibility in the whole continent. But now the tension of occupation has forced them to use and sacrifice these qualified talents.

Fierce fighting continued unceasingly until the evening of the third day, exhausted on both sides. The reinforcements led by Luo Ming and Lin Yi arrived at this time. This unit was separated in the battle with casualties, and in addition to the fact that a large number of men were constantly left behind to guard the prisoners or take care of the wounded, less than 300,000 people actually rushed to protect the castle and reinforce them. The army of the Ma Huaishan Kingdom suffered heavy losses after days of hard fighting, but it still retained at least 600,000 troops. Seeing the people of Black Cloud City arrive, Luo Zhen smiled instead of being angry. He has not been idle for the past few days, and almost every hour he will send scouts to detect movements on various battlefields.

He now knew that both the army of the Qilin Kingdom and the army of the Northern Alliance had collapsed, but he didn't care at all. Because after a lot of attrition, there are not many people left in the army of Black Cloud City at all. And after continuous battles, marches, battles, marches, and so on, their physical condition is much worse than that of his troops here. The tired army, which has a much smaller number than him, is already at the end of the crossbow, how can he fight him?

The rout of the Qilin Kingdom and Black Cloud City was good news for him, and now he was the only one in the world who could win the victory and defeat the so-called invincible Black Cloud City in one fell swoop.

Luo Zhen ordered 100,000 men to continue the attack on the Mingyang Fort defensive line. It is necessary to maintain strong pressure on the defensive line, and not allow them to take the opportunity to fight and attack from both sides. The rest of the men marched out of the castle defense line and lined up on the outskirts to meet them. Luo Zhen was very anxious about the fact that he couldn't attack the castle for a long time, and thought: I see what else you have to rely on to fight in the field!
