Just when Liu Qi was developing with peace of mind and accumulating energy, Cao Cao, Yuan Shao and Liu Bei were also desperately preparing for war, especially Yuan Shao and Liu Bei, who had all experienced a great humiliation and decided that this time they must wash away the shame and then fight for hegemony in the world.

Since Tian Feng was pardoned and reinstated, Yuan Shao was encouraged by Tian Feng after the defeat of Guandu, and although he lost all the areas south of the Yellow River, the whole Hebei region became the same enemy. During these two years, Yuan Shao accepted Tian Feng's construction and developed production with peace of mind, and at the same time actively recruited and trained soldiers, so that the economy of the four prefectures of Hebei was gradually restored.

Yuan Shao also ordered Guo Tu to contact Liu Bei, and took advantage of Guan Yu's killing by Cao Cao to form an alliance with Liu Bei, agreeing to jointly send troops to deal with Cao Cao in the future, and ordered Feng Ji to continue to form an alliance with Liu Qi, hoping that Liu Qi could restrain Cao Cao in his rear, so that Cao Cao could not fight on the front line with peace of mind.

After two years of preparation, in the seventh year of Jian'an, in March, Yuan Shao saw that Hebei's economy had recovered, grain and grass were abundant, and the soldiers were strong and strong, even compared with the eve of the battle of Guandu, they were not weak at all, and a competitive heart could no longer hold back, so he decided to contact Liu Bei and Liu Qi to conquer Cao Cao again.

However, after Yuan Shao raised the matter, he was once again opposed by Tian Feng.

Tian Feng's opinion is almost exactly the same as before the last battle of Guandu: "Hebei's economy has just recovered, the army and the people have just recovered from the wounds of the war, if you start the war rashly now, I am afraid that the efforts of the past two years will be ruined, not to mention that Cao Cao is no longer what it used to be, since the relocation of the capital to Luoyang and the construction of Tongguan, the ruling nest has no worries, and he has obtained the surrender of Zhang He, Gao Ran and 20,000 surrendered troops under his command during the battle of Guandu, as well as the efforts of the past two years. The troops that can be mobilized under his command are no less than 50,000, and Xu Yanyu has obtained sufficient grain and grass in the four states, even if the lord does not make any mistakes this time, I am afraid it will be difficult to hold on to it, and now it is a great blessing that he does not take the initiative to attack us, how can we offend him lightly? ”

Yuan Shao was deeply dissatisfied with Tian Feng's remarks, and now he has endured it for two years, just to be able to defeat Cao Cao in one fell swoop, in order to wash away the shame of the past, seeing that there is hope for revenge, how can he give up? Then he said to Tian Feng: "Although Cao Cao is strong, but we are not weak, besides, we still have Liu Qi and Liu Qi, the two alliances, if the most powerful of the group today are the four of us, we concentrate the three most powerful forces to deal with Cao Cao, can't we win?" ”

"The lord doesn't know, Tongguan is solid, it's really unimaginable, with Liu Bei's heroic character, he will definitely not pay too much sacrifice in order to attack Luoyang, once the attack is frustrated, I am afraid he will give up immediately, not to mention that the lower officials heard that now Hanzhong Zhang Lu is attacking Liu Zhang in Yizhou, Liu Bei will definitely help Liu Zhang attack Zhang Lu in the name of the Han clan, so this person can't be counted on at all, and Liu Qi is even more cunning, the last time we fought in Guandu, he clearly promised to attack Xuchang, As a result, Xuchang was returned to Cao Cao at a critical moment, thus ensuring Cao Cao's final victory, so this time, Xia Guan believed that even if Liu Qi really cooperated with us, at most he would only attack Xuzhou and Yuzhou, which would not play much role for us, and once we failed, I am afraid that all the land in Hebei would be owned by Cao Cao. ”

Tian Feng sighed and continued: "According to the opinion of the lower officials, we might as well still rest and recuperate in order to accumulate strength, now that Liu Qi is growing in his wings, the threat to Cao Cao is becoming more and more severe, and the contradictions between the two sides are getting bigger and bigger, once there is a war between them, it will be a great opportunity for us to sweep the Central Plains." ”

But how could Yuan Shao have the patience to wait? Therefore, I couldn't listen to Tian Feng's suggestions at all, if it weren't for the fact that the other party had made important contributions to Hebei's economic recovery, I am afraid that Yuan Shao would have imprisoned Tian Feng as he did before the Battle of Guandu.

However, even now, Yuan Shao only left Tian Feng and the trial to guard Jizhou, led the generals under his command, and the eldest son Yuan Tan, the youngest son Yuan Shang and others led 80,000 foot cavalry, sent troops to Lin Xi, preparing to seize Hanoi first, and then occupy Luoyang to welcome the Son of Heaven.

At this time, Tian Feng built yì Yuan Shao steadily and steadily, first cooperated with Liu Qi, attacked Zang Ba in the north and south, carved up Qingxu Erzhou, and then tried to Yanzhou, so steady and steady, although he could not occupy Luoyang, but he could also subdue the old land, and then cooperate with Liu Bei and Liu Qi to get to the Central Plains, but it was a pity that Yuan Shao wanted to fight a decisive battle with Cao Cao and completely eliminate Cao Cao, so he didn't listen to Tian Feng's construction at all.

At the same time, Yuan Shao ordered his nephew, Bingzhou Assassin Shi Gaogan and the self-appointed Hedong Taishou Guo Yuan to lead an army of 20,000, and united with the Southern Xiongnu Shan Yu Luan Tihu Chuquan and Guanzhong Liu Bei, a total of 70,000 troops to attack Hedong, in order to jointly attack Luoyang in the future, and ordered Feng Ji to invite Liu Qi to attack Xuzhou, so as to force Cao Cao's general Zang Ba stationed in Qingzhou to return to help and reduce the military pressure on the eastern front.

Since Cao Cao moved the capital back to Luoyang, how could he not be prepared for the Hanoi region, which was the gateway to Luoyang? As early as after the victory in the battle of Guandu, Cao Cao ordered Hanoi Taishou Wei to strengthen the city in Shanyang State, and sent Xue Hong, Miao Shang, Shi Lian and other generals to divide the city of Houjia, Xiuwu and Turbidity Deer, and set up beacon towers along the road between the three cities, one city was besieged, and the other two cities immediately gave full assistance, and the enemy must be outside the country.

When he heard that Yuan Shao had raised troops again, Cao Cao did not dare to slack off, and immediately dispatched Xu Huang, Le Jin, Xiahoudun, Xiahou Yuan, Cao Hong, Cao Ren and other generals to lead the army to Hanoi and fight a decisive battle with Yuan Shao.

And when Guo Jia, Xun You and others heard that the target of Yuan Shao's attack was Hanoi instead of Qingzhou, they couldn't help but celebrate, because they knew that if Yuan Shao led the army to recover the plain first, and then cooperated with Liu Qi to subdue the entire Qingzhou, then the land of Qingxu may be difficult to keep, and as soon as Qingxu is lost, Yuzhou and Yanzhou will face tremendous pressure, so that even if Luoyang is safe and sound, I am afraid that they will definitely be compressed in a corner of the Central Plains, and it will be difficult to have room for development in the future.

Now Yuan Shao has a strong army and directly attacks Hanoi and Luoyang, which are heavily defended by his own troops, which will doom Qingzhou to no danger, since Qingzhou is safe, Liu Qi will not dare to rashly attack Xuzhou, and Cao Cao is also confident that with the strength in his hands, he will definitely be able to defeat Yuan Shao.

Cao Cao knew that this time, although Yuan Shao had put together an army of 80,000, plus an army of 70,000 to attack Hedong, a total of 150,000 people, he would not give up until he was wiped out. If this time his side wins again, it is estimated that Yuan Shao will not even have the strength to suppress the civil strife, and then he will be able to easily occupy the entire Hebei region, if he gets the entire Hebei region, and then there are the four states of Qingxu and Yanyu in the Central Plains, it can be said that the twelve states of the Han Dynasty will have seven of them, and it is absolutely no longer a dream to annex the world based on these seven states.

So this time, Cao Cao also made enough preparations, and even arranged the deployment of attacking Hebei after defeating Yuan Shao.

"Fengxiao, how did Liu Bei's affairs go?" Cao Cao was still a little worried about Liu Bei in Guanzhong, so he said to Guo Jia.

"Hehe, Xia Guan is preparing to report this matter to the prime minister. Xiaguan has invited Yang Fu to Jincheng to see Han Sui, Yang Fu word Yishan, Tianshui people, before the battle of Guandu had been to Xu Du to see the lord, and then the heart to the lord, and then the battle of Guandu we won, Yang Yishan is even more devoted to the lord, this person is now Liangzhou don't drive, has repeatedly persuaded Liangzhou to assassin Shi Weiduan loyal to the court. The lower official knew that this person was loyal, so he ordered the envoy to Liangzhou, and asked him to persuade Han Sui to attack Ma Teng, and to be loyal to the imperial court, and he would definitely not hesitate to reward him in the future. ”

"Hehe, Feng Xiao expected the enemy to be the first, and he had already made preparations, and he was worry-free. The prime minister went to the palace to ask for a decree, and named Han Sui as the general of the expedition to the west, the Marquis of Jincheng, and led the right to support the wind. I also know him, and I am repairing a book with him, so I think he will also sell me the face of this old friend. As long as Ma Teng is defeated and Liu Bei loses foreign aid, what strength do I think he will have to attack my Hedong? ”

"Slow down." Guo Jia saw that Cao Cao was about to write a recital, and hurriedly said: "In the opinion of the following officials, with Han Sui's own strength, it is not only difficult to defeat Ma Teng, but it will also make Ma Teng's strength stronger, even if he defeats Ma Teng, I am afraid it will be difficult to deal with the coalition army of Gao Gan, Hu Chuquan and Liu Bei, so it is better for the prime minister to reward the Xiliang generals Liang Xing, Yang Qiu, Li Kan, candidates, Cheng Yin, Zhang Heng, Ma Wan, Cheng Yi, these seven generals have always been subdued by Han Sui, as long as the lord rewards them, and then unite Han Sui, will definitely be able to defeat Ma Teng, even Hu Chuquan may be afraid of Han Sui's might and retreat, so Liu Bei will be threatened by the back road, so he has to divide his troops to deal with Han Sui, leaving only Gao Gan all the way, so there is nothing to fear. ”

Cao Cao was very satisfied with what Guo Jia said, he smiled and nodded, and then immediately presented to the Son of Heaven, recommending Han Sui as the general of Zhengxi, the Marquis of Jincheng, leading the right to support the wind, and praising his loyalty to the Han Dynasty, and recommended Liang Xing, Yang Qiu, Li Kan, candidates, Cheng Yin, Zhang Heng, Ma Wan, and Cheng Yi as miscellaneous generals, and named liehous, so that they were loyal to the Han family and loyal to the imperial court, and at the same time comforted Yang Fu, named him a marquis, promoted to serve the imperial history, and treated his family well, so that he stayed in Han Sui's camp to help Han Sui encircle the warlords of Liangzhou, After the crusade against Ma Teng, he wrote a letter to Han Sui in his personal name, encouraging him to be loyal to the Han family and hinting that he could sit in Guanzhong in the future, so he led the army to Hanoi.

In this way, two years after the Battle of Guandu, another large-scale war began, and the impact of this decisive battle was even greater than the Battle of Guandu, and this war even opened the curtain of the entire Three Kingdoms era.
