After Cao Cao completely destroyed Yuan Shao, he killed all three of Yuan Shao's sons, but Yuan Shao's eldest son Yuan Tan had left his bloodline.

At this time, Lu An's army also began the Northern Expedition, and in order to disrupt Cao Cao faster, Lu An let Zhao Yun and Zhang Liao lead 20,000 cavalry first, and he personally led a large army to march behind, but on the way to the Northern Expedition, Liu Zhang of Bashu sent a letter for help, and the other party had been beaten by Liu Bei and had no power to fight back, and almost all of Bashu was ruled by Liu Bei, leaving only the general Zhang Ren struggling to support a Yongan County.

After some thought, Lu An was afraid that Liu Bei's complete unification of Bashu would lead to a bad march into Shu in the future, so he decided to divide his troops, and he divided the army of more than 200,000 into two parts, one part was under the command of Zhou Yu and Gan Ning of Jingzhou, and rushed directly from Jingzhou to aid Liu Zhang, not seeking to break the enemy, but only to hold on, while the other part was led by himself to continue the Northern Expedition.

At this time, Zhao Yun and Zhang Liao's vanguard cavalry has entered the hinterland of the Central Plains, which has brought great trouble to Cao Cao, but after Xun You's dedication, Cao Cao seized the opportunity to trap Zhao Yun and Zhang Liao's cavalry army in one fell swoop, preparing to wipe out all these cavalry, at this most critical juncture, Zhao Yun let Zhang Liao command the cavalry, and he left the broken back, and Zhang Liao also began to play his own command ability, when Zhao Yun dragged Cao's army to death, Zhang Liao used the shortest time to lead the cavalry in a desperate situation to break out of the encirclement.

But although the cavalry army was killed out of the encirclement, but Zhao Yun was trapped in the enemy formation after being broken alone, Cao Cao greatly admired Zhao Yun's martial arts comparable to Lu Bu, and wanted to surrender, but was drunk back by Zhao Yun, and finally Cao Cao could only order to kill, but at this last moment, Zhao Yun's gentian characteristics broke out, and all aspects of the attributes were temporarily improved in a short period of time.

And after a period of marching, Lu An finally led the army to the Central Plains, and Cao Cao had a confrontation before the war, in the face of old friends, both of them felt a little tricky, and Cao Cao was a little unhappy with Lu An, and asked Lu An why he dared to divide his troops in a decisive battle, whether he looked down on him Cao someone, but Lu An was confident, in addition to being invincible in the world of martial arts at this time, he also got the second half of the Bai Qi military book given by the system, the wonderful marching method, plus the formation map of the first half, The two merged into one, and finally formed the Marshal Technique of the Great Heavenly Sage, and he had no opponent in the world in terms of commanding the battle array, so he had this kind of confidence.

In the end, Lu An and Cao Cao started a fight, and the result was naturally self-evident, ending with Lu An's complete victory, Cao Cao killed himself, and the Xiahou brothers and Dian Wei Xu Chu and others died one by one.

After Lu An settled Cao Cao's family, he rushed to the Jingzhou battlefield to support, because of the presence of Zhou Yu and Gan Ning and other strong generals, although Liu Guanzhang brothers and Wolong Phoenix Chicks tried their best to attack, but finally failed to capture Yong'an County in a short time.

At this time, Lu An also led the army to Yong'an, in the face of Lu An, who almost dominated the world, Liu Bei and Zhuge Liang were powerless to return to the sky after all, and finally completely defeated.

At this time, the world was unified, Lu An found that he had no way out, and had to go to the throne and ousted Emperor Han Xian, and then, Lu An ruled the world for thirty years, creating an unprecedented peaceful and prosperous era, and then, the system that had not moved for a long time released the task again, and this time the task reward was ----- to ascend to the immortal world.
