In May, when the war in the Western Regions had not yet ended, the Northeast Battlefield, where the weather had warmed, was now beginning to be tense, and a decisive battle of life and death could break out at any time.

Gongsun Du, the overlord of Liaodong, now has a word of suffering, originally thought that with the soldiers and horses in his hands, it would be enough to sweep Karasuma and Goguryeo, but since the war began last year, not to mention the loss of troops, he still has not seen the dawn of victory.

In the summer of last year, Gongsun Duqin led a large army from Xigaima, echoing with the Liao Hua army sent from Xi'an Ping, and drove Goguryeo's army back to the domestic city along Hadaling and Longgang Mountain respectively, and occupied the Susheng Bone City, stopping the attack at the upper reaches of the Mazi River (Yalu River).

It's not that Gongsun Du didn't want to attack the domestic city in one go, but it was already in the middle of winter, and it was really a very dangerous thing to fight against the hardy Goguryeo people on the cold battlefield, and to cross the mountainous jungle.

Gongsun Du then combined his troops with Liaohua's troops, and all entered the city of Susheng to avoid the cold, waiting for the next spring to bloom before fighting.

In the long thing, Guo Huai, who was stationed in Gaoxian City, sent a secret report to Gongsun Du, proposing to unite the rest of the people to annihilate Wusun and Xianbei first, and then move eastward, and attack Goguryeo with a three-way army. Guo Huai unabashedly suggested that Gongsun Du might as well blame Youzhou or Fuyu Guo and take the means of killing people with a knife to eliminate the threat in the northern part of Liaodong County.

Since Gongsun Du was able to personally lead a large army to drive the Goguryeo people back to the domestic city, it shows that he is a commander who understands the art of war, so he naturally has an independent judgment on Guo Huai's suggestion.

After repeated evaluation, Gongsun Du agreed to Guo Huai's suggestion, but he was a little unconfident in the strength that Guo Huai currently controlled. So he ordered his eldest son Gongsun Kang to urgently recruit 20,000 recruits in the Liaodong region and handed them over to the generals Jiao Touch and Xu Miao for training, and the 10,000 troops that originally defended the Xiangping area were led by Liupu to Gaoxian to join Guo Huai and be dispatched by Guo Huai.

Since then, Guo Huai has 25,000 soldiers under his command, although there is still a gap with the total strength of the Karasuma people, but if you add the tens of thousands of troops of the northern neighbor Fuyu Kingdom, it is enough to fight a decisive battle with the Karasuma people and the Goguryeo people.

Guo Huai saw that Gongsun Du supported him so much, and even sent all the troops to defend Xiangping, the old nest, and at the same time, he did not dare to be careless, so he sent an envoy to Fuyu for the second time to lobby.

If it is said that Fuyu Guo was still easy to be fooled when the Blue Wolf Army had not yet arrived, then Fuyu Guo, who is now in charge of Zhang Xiu and Li Hui, is not so easy to be used as a gun.

When the envoy sent by Guo Huai went to Changchun City, he wanted to enter the city to find out, but he was very politely rejected by the rest of the people, on the grounds that the city was still under construction and it was inconvenient for outsiders to enter and visit. This reason is also straightforward, that means that this is our city, if you come in and understand the mechanism, when the two sides turn against each other in the future, won't my city be dangerous?

Although he did not enter Changchun City, the envoy still saw a large number of Fuyu soldiers coming in and out along the road, and roughly estimated that there were no less than 20,000 people.

The messenger continued northward, and after walking for several more days, he finally came to the place where the lord of Fuyu lived. After meeting the lord of the country, the envoy presented a gift carefully prepared by Gongsun Du, and immediately won the joy of the lord of the country, so he treated the envoy as a guest. The envoy then proposed that the two sides send a coalition army to attack the Karasuma Xianbei people from the northeast and southeast directions, respectively.

The lord of the country hesitated for a long time, and finally raised his worries, saying what if he could not defeat the Karasuma people? The envoy laughed secretly in his heart, but he said that as long as the two families formed an alliance, no matter which one the Karasuma people attacked, the other family could not stand idly by, so the lord's worries were purely superfluous.

Under the skillful words of this envoy, the lord of Fuyu finally agreed to form an alliance with Liaodong and sent 30,000 troops to attack the Karasuma people.

The messenger who returned to Gao Xian with good news was greatly appreciated and rewarded by Guo Huai. So in the following time, Guo Huai trained his 25,000 soldiers all day long, and only after the weather warmed up, he launched a final decisive battle against the Karasuma and Xianbei people.

Guo Huai was carefully preparing here, and Zhang Xiu did not stop at all.

Long before Guo Huai sent an envoy for the second time, Zhang Xiu received a secret report from Crouching Tiger City, and Zhao Xing not only agreed to Zhang Xiu's proposal, but also temporarily transferred the Flying Tiger Army to Youzhou to cooperate with Zhang Xiu's operation. After Zhang Xiu saw Zhao Xing's arrangement, he was very excited, and he no longer had to worry about the Karasuma people and the Xianbei people breaking into Youzhou to cause trouble to the people, so he calmed down and planned how to calculate the Karasuma people, the Xianbei people and Guo Huaijun.

At that time, when the envoy sent by Guo Huai came to see the lord of Fuyu, Li Hui secretly followed him to the place where the lord of Fuyu was, and took some shortcuts to arrive first. The words of the lord of Fuyu to answer the envoy were all thought out by Li Hui in advance, which was both silly and easy to believe, but even Guo Huai did not find the problem.

After deciding on the plan of the two families to send troops together, Zhang Xiu immediately sent the Shadow Team members to secretly go to the north of Youzhou to contact the Flying Tiger Army, and inform the Flying Tiger Army of the specific battle plan of the Blue Wolf Army.

The Flying Tiger Army, which had arrived in Yuyang County, Youzhou, immediately went north under the leadership of Dian Wei under the leadership of Dian Wei, and after crossing the upper reaches of the water, they entered the designated interception position.

In order not to let Guo Huai see the flaws, Zhang Xiu always stood still, waiting for Guo Huai's proposed time to send troops together, anyway, by now, the Karasuma people and the Xianbei people have become fish on the board, and they can cut it as they want, but the side that eats the fish bones must not be the Blue Wolf Army, nor the Flying Tiger Army.

In order to cooperate with Guo Huai's actions, Gongsun Du temporarily stopped his plan to attack Goguryeo in the east, and instead placed his troops between the Hadaling Mountains, where the Fuyu Kingdom and the Goguryeo people were interconnected, to prevent the Karasuma people from turning north from invading the Fuyu Kingdom, and then fleeing into Goguryeo from the territory of the Fuyu Kingdom, and colluding with the Goguryeo people to unite against him.

When Gongsun Du secretly formed an alliance with Fuyu, the Goguryeo people who were beaten by Gongsun Du were not idle. They secretly sent an envoy to make contact with the Karasuma people and proposed that the two sides work together to attack the castle of Changchun Castle. As long as they took the southern part of Fuyu, Goguryeo and Karasuma would be able to join forces and fight against the Gongsun army in the south.

Seeing that the desperate Karasuma and Xianbei people were very interested in the suggestions put forward by the Goguryeo people, they also felt that the current plan must occupy a favorable terrain and resist Gongsun Du with the Goguryeo people back to back in order to have a chance to survive, so they hit it off with Goguryeo and decided to join forces to besiege Changchun City.
