In history, Zhang Yang had twice rescued Emperor Xian in danger, the first time was when Emperor Xian was forced to Anyi by Li Guo's coalition army, at that time most of the officials and palace people were taken away by Li Guo, and the clothes were robbed, and even the food was not enough, fortunately Zhang Yang sent thousands of people to pay rice tribute, and at the same time, Hedong Taishou Wangyi also sent a lot of silk, which temporarily solved the life problem of the Son of Heaven's team.

Zhang Yang hoped that the Son of Heaven would go to Luoyang when he was in Anyi, but those generals all had evil intentions, and the Son of Heaven was powerless, so he finally rejected Zhang Yang's proposal. But a few months later, the team of the Son of Heaven finally came to Luoyang, and at this time their food was almost exhausted, and it was Zhang Yang who sent someone to repair the palace in Luoyang in advance, and brought another batch of food in time.

After Zhang Yang settled Emperor Xian of the Han Dynasty in Luoyang, he gave up the righteousness that the princes could not ask for without a trace of clouds, handed over the power to the imperial court very uprightly, and went out of the town to guard the Son of Heaven.

Zhang Yang is a good person, but just a good person can't win the allegiance of his subordinates.

In August of the first year of Jian'an (196), Cao Cao led troops to Luoyang to pay tribute at the invitation of Dong Cheng, and took the opportunity to report the sins of Han Xian and Zhang Yang. Han Xian, who had always been at odds with Cao Cao and Dong Cheng, immediately ran to Yang Feng, who was stationed in Liang County, to offer the emperor's memory and Han Xian and Zhang Yang's escort and rescue credit, and ordered that their faults should not be investigated.

But in history, this is not the first time Cao Cao has welcomed the Son of Heaven, in fact, as early as a few months ago, Cao Cao sent Cao Hong to lead his troops westward under the persuasion of Xun Yu and Cheng Yu, but unfortunately he was stopped by General Wei Dong Cheng and Yuan Shu's general Chang Nu according to the danger, but what people didn't expect was that it was Dong Cheng who stopped Cao Cao at the beginning and let Cao Cao in.

After Cao Cao arrived in Luoyang, he sat with Dong Zhao, and Cao Cao asked Dong Zhao: "Now that I am here, what strategy should I take?" ”

Dong Zhao said: "The general rebelled against the soldiers, killed the rioters, entered Beijing to worship the Son of Heaven, and assisted the royal family, which is comparable to the five hegemons of the Spring and Autumn Period." However, the generals below have different hearts and may not be willing to obey you. Now that you are staying here to fight the Son of Heaven, the situation is not in your favor, and you can only transfer the Holy Driver to Xu County. Of course, the imperial court had just returned to the old capital after the exile, and no matter near or far, they were looking forward to settling down one morning. Now the migration of the holy car again does not satisfy everyone. To do something extraordinary, you have to have measures that go beyond the norm, and I hope that the general will plan how to do it with more advantages and fewer disadvantages. ”

Dong Zhao told Cao Cao that if he wants to be an extraordinary person, he must do extraordinary things, and if he wants to do extraordinary things, he must have extraordinary decisions.

Cao Cao said again: "This is exactly what I intended. But Yang Feng is very close, in Liang County, I heard that his team is excellent, can he not become a hidden danger to me? ”

Cao Cao said that I can do it completely, but please help me solve my concerns first.

So Dong Zhao is any problem to solve Yang Feng?

Dong Zhao replied to Cao Cao like this: "Yang Feng lacks protection assistance and will return to obedience alone." The affairs of Zhendong and Feiting were all confirmed by Yang Feng, and I heard that he wrote a letter ordering his soldiers to restrain him, which is enough to see his integrity. Messengers should be sent from time to time to thank him for his kindness, so as to calm his mind. It is said that "the capital is short of food, and I want to temporarily move the holy car to Luyang, which is closer to Xu County, and it is easier to transport it in a different way, so I can not worry about the serious shortage of food." Yang Feng is brave and lacks thought, and he will definitely not suspect us, and when the envoys of the two sides have exchanged, it will be enough to determine the plan. Where can Yang Feng become a hidden danger! ”

Yang Fengyong was brave and thoughtless, Dong Zhao solved him with only one move to paralyze him, now Cao Cao has no problem, as for Zhang Yang, who is "Fengtianzi, inaction", does he still need to be considered by them?

Cao Cao was awarded to Emperor Jie Yue in Luoyang after entering, recorded Shang Shushi, and served as the lieutenant of Si Li, he took advantage of Zhang Yang and Yang Feng's soldiers to drive away Han Xian, and then did three things: kill Zhongtai Chong, Shangshu Feng Shuo, etc., which is called "asking for guilt"; Feng Dong Cheng, Fu Wan, etc., is called "rewarding merit"; Posthumously awarded the shooting sound captain Fu Jun, called the "Festival of Death".

Then Cao Cao followed Dong Zhao's strategy, successfully paralyzed Yang Feng, and welcomed the Son of Heaven to Xu County, Dong Cheng, Dong Zhao and civil and military officials came here, and Cao Cao simply renamed this place Xuchang as the capital of the Han Dynasty. Yang Feng came to his senses and sent troops from Liang County to rob Emperor Xian, but it was too late.

After Cao Cao moved the capital to Xuchang, Yang Feng was very dissatisfied with it, so Yang Feng and Han Xian led the army to Dingling County in Yingchuan County to plunder and harass, Cao Cao ignored it at first, but this was still just a paralyzing strategy, in October of the same year, Cao Cao took advantage of his unpreparedness to suddenly attack Yang Feng's military camp in Liang County, Yang Feng and Han Xian lost their foothold and went east to Yuan Shu.

The other two important generals of the White Polish Army, Hu Cai and Li Le, died one after another. Hu Cai once wanted to attack Han Siam, but was blocked by Emperor Xian, and he later stayed in Hedong County to be harmed by the resentful family. Li Le stayed in Hedong and later died of illness.

Cao Cao took advantage of the fact that others had not had time to react, and moved the emperor to the capital, so that the emperor was freed from the control of other forces and was controlled by himself.

How fast did Cao Cao attack at that time? Cao Cao was appointed as the captain of the school by Emperor Xian of the Han Dynasty on the Xinhai day of August in the first year of Jian'an, and only nine days later, that is, on the day of Gengshen, Cao Cao completed the relocation of the capital.

After the capital was moved, the base camp of Cao Cao's group was also moved from Juancheng, the original Yanzhou administrative office, to Xuchang.

Cao Cao's attack on the issue of Fengtianzi was not only accurate, but also faster, and finally accurately grasped the opportunity, while Yuan on the other side was probably still thinking about it at this time.

After that, Cao Cao also stepped up his pace to cut off dissidents and increase his power. He first challenged the most influential Sangong and dismissed the Taiwei Yang Biao and Sikong Zhang Xi; secondly, he killed Zhao Yan; again sent troops to recruit Yang Feng to relieve the worries of the close soldiers; Finally, on the one hand, in the name of the Son of Heaven, he condemned Yuan Shao and dealt a blow to his arrogance, and on the other hand, he ceded the general to Yuan Shao to stabilize the enemy.

In November of the same year, Emperor Xian of the Han Dynasty made Cao Cao the commonplace, and Cao Cao officially took over the political and military power.

Since then, in a sense, Cao Cao is the imperial court, and the imperial court is Cao Cao.

In the first year of Jian'an, the capital was moved to Xuchang, which was also a demarcation point for the development of Cao Cao Group.

After Cao Cao was appointed to the Son of Heaven, he not only won Dong Zhao, Zhong Xuan and other former Han ministers, but also won the hearts of a large number of scholars in the world. After Xun Yu's recommendation, Guo Jia and Xun Yu came to vote successively, and Du Xi and Zhao Yan, who avoided the chaos in the south of the Yangtze River, also returned to Xuchang the following year.

Not only that, but Cao Cao also gained a huge political advantage, which made the other princes inherently inferior to Cao Cao. For example, although Lü Bu actually owned Xuzhou, he had to send someone to Cao Cao, hoping that the imperial court would officially appoint him as the pastor of Xuzhou.

After Cao Cao moved the emperor eastward, he was able to "coerce the Son of Heaven and order the princes", which made Cao Cao's group once again achieve unprecedented development, which laid a solid foundation for Cao Cao's future unification of the north, and was also an important reason why Wei had an advantage in the future confrontation between the three kingdoms.
