The Goguryeo army attacked Liaodong according to the previous plan, and the road was very smooth, Ulji Wende took the lead in occupying Yancheng and began to build fortifications in Yancheng to strengthen the defense, while Yuangai Suwen led an army of 30,000 to kill Liucheng.

This division of labor is actually Yuan Taizuo's selfishness, he thinks that the Khitan army attacking the south must be to attack Liucheng with all its might, even if it can't capture Liucheng, it will greatly weaken Liucheng's defense, and Yancheng is not affected by the Khitan, I'm afraid it will be difficult to capture.

So Yuan Taizuo won his son to attack Liucheng, but he couldn't have imagined that the Khitans attacked Yancheng first, and then turned to attack Liucheng, Yancheng was already an empty city, and Liucheng was still strong.

Yuangai Suwen learned that Yizhi Wende had occupied Yancheng, he was secretly annoyed in his heart, but he had no choice but to lead an army of 30,000 to march in the direction of Liucheng, and three days later, the army arrived in Liucheng.

At this time, the fire of Liucheng has just dissipated, the bones of the Khitan soldiers have been burned and buried, but the wilderness outside the north and south cities is still bloodstained, shocking, the Sui army is densely covered with foot pits within a mile from the north and south city walls, and the pits are inserted with highly poisonous bamboo sticks, but the tribulus terrestris thorns are not deployed for the time being, and they will use trebuchets to scatter them during the battle.

Although the soldiers of Liucheng experienced a bloody battle with the Khitan army, with the arrival of reinforcements, their combat effectiveness became stronger, and 30,000 soldiers of the Sui army and militia soldiers built the city without leakage.

Standing at the head of the city, looking at the Goguryeo army from a distance, Yang Shanhui frowned and said, "Didn't you say that there are 40,000 troops on the other side of Xincheng?" Why only 30,000 came, could it be that this is the army in Liaodong City? ”

Du Yunsi smiled slightly: "This should be the Goguryeo army in Xincheng, the army must not go out of the nest, the army must be left to guard the nest, and the army must transport food and ensure logistics and supplies, so it is normal to only come with 30,000 troops." ”

Lu Chifeng next to him laughed and said: "In this way, our troops will not suffer at all, even if we don't defend the city, we can defeat them if we pull the army out to fight him." ”

"General Lu is wrong, defending the city is more advantageous than besieging the city, the casualties of the general army are only half of the opponent's, of course you have to defend the city, why go to a decisive battle with them?"

"Don't forget, there are also General Pei's 30,000 cavalry, as long as 10,000 cavalry can strangle them, just like crushing a swarm of ants."

Everyone said a word, and finally everyone laughed, after the bloody battle, everyone was full of confidence in defending the city, and they were no longer as nervous as they were when they faced the Khitan army at the beginning.

Although the joke was made, everyone still valued this Goguryeo army very much, and they all saw that the camp of this Goguryeo army was very neat and uniform, and the army was not as noisy and chaotic as the Khitans, everything was in order, which was in stark contrast to the chaos of the Khitan army.

From these details, it can be seen that this army is a good fighting army, and the commander of this army, Yuan Gai Suwen, is definitely not a legendary playboy, but a person with strict military discipline and careful consideration.

There is a beacon in Liucheng on Bijia Mountain thirty miles away to the south, and there is a beacon every thirty miles to the south, which extends to Linyu Pass in Beiping County.

But this time the Goguryeo army came to attack, but the beacon was not ignited, on the one hand, the Sui army had already known, on the other hand, the beacon also had an important role, it temporarily served as an intelligence transit station, an eagle station, and the cavalry of Liucheng and Pei Xingyan exchanged intelligence through this eagle station, so the Sui army could not expose the location of this eagle station for the time being.

The eagle flew south, and half an hour later two horsemen rushed out of the woods under Beacon Hill and headed northwest.

Pei Xingyan's 30,000 cavalry is currently stationed in the grassland of the Xi people, after following the Khitan attack on Liucheng and suffering heavy casualties, but Pei Xingyan just needs the grassland to garrison the cavalry, and the Xi tribe is located in the west of Liucheng County, the grassland is adjacent to Liucheng County, one hundred and twenty miles away from Liucheng, is the best place to garrison cavalry.

After Pei Xingyan sent a request to Su Zhi, the chief of the Xi people, Su Zhi happily agreed to Pei Xingyan's request for garrison, and took the initiative to undertake the supply and camp tent of 30,000 Sui cavalry.

In the evening of this day, the two cavalrymen handed over the eagle letter sent by Liucheng to Pei Xingyan, in the big tent, Pei Xingyan carefully read the eagle letter, the letter was written by Du Yunsi to himself, one is to tell him the distribution of the Goguryeo army, and secondly, to remind him not to underestimate the enemy, this Goguryeo army is well-equipped and is a strong combat elite soldier.

At this time, a soldier reported at the door of the tent: "General Qiyu, Song joins the army and asks to see!" ”

Song joined the army is Song Zhengben, Zhang Xuan sent him to follow Pei Xingyan into Liaodong and give advice for Pei Xingyan, but the two don't get along very well, Pei Xingyan is proud, among all the civilian officers, he only serves Li Qingming alone, and even his brother Pei Hong rarely interacts, not to mention that Song Zhengben, who was once Dou Jiande's strategist, and Song Zhengben himself is also very high-minded, and will never bend flattery, so Pei Xingyan doesn't pay much attention to Song Zhengben, Song Zhengben doesn't come to Pei Xingyan until the critical moment.

"Let him in!"

After a while, Song Zhengben walked into the big tent quickly, and as soon as he entered the tent, he said: "Now is the opportunity to attack the Goguryeo army in Liucheng, what are the generals waiting for?" ”

Pei Xingyan saw that Song Zhengben was speaking very impulsively, and he was really unhappy in his heart, and said coldly: "The Goguryeo army has just arrived in Liucheng, the morale is booming, and there is still a lot of grain and grass in hand. ”

"First, the general did not know how much grain they had in their hands; Second, if they find that 30,000 cavalry are hiding in Liaodong, they will definitely retreat, and the general will lose the opportunity. ”

Pei Xingyan was even more unhappy in his heart, and he said proudly: "I, Pei Xingyan, led the cavalry across Hebei, and I have never suffered defeat, but Dou Jiande has joined the army as a strategist but has never won a battle, and it is time to introspect when I join the army." ”

These words tore apart Song Zhengben's scars, and Song Zhengben also said angrily: "It is my duty to persuade the general to send troops, why did the general hurt people?" ”

"Really? Then I apologize for joining the army. ”

Pei Xingyan apologized, but he didn't mean to apologize, Song Zhengben turned around and left, walked to the door of the tent and stopped: "I will persuade the general again, now is the best opportunity, please don't let the opportunity slip away." ”

"I see, thank you for your advice to join the army!"

Song Zhengben couldn't help but hear what he said, so he shook his head and walked away quickly, Pei Xingyan looked at him and walked away, couldn't help sneering, and then said to his own soldiers: "Find General Chen Jing!" ”

After a while, a young general appeared at the door, bowed down and clasped his fists and said, "The last general will see the general!" ”

This general is called Chen Jing, is Pei Xingyan's former deputy general Chen Xu's younger brother, after Chen Xu was killed in the attack on Zhang Jincheng, Zhang Xuan promoted his brother Chen Jing to lieutenant, continued to follow Pei Xingyan, fought in the south and north, and was promoted to Huya Lang General after accumulated merit, and was one of Pei Xingyan's right-hand men.

Pei Xingyan groaned and said: "The 30,000 troops of Goguryeo have arrived in Liucheng, and General Du Yunsi said that they did not carry much baggage, did not see the siege ladder, and did not have much food, indicating that their baggage and grain were transported later, and cutting off their military rations was the way to win, so I will hand over this task of cutting off their logistics replenishment to you." ”

"Obey the order!"

Pei Xingyan stood up and walked to a map on a wooden board, he pointed to the map and said to Chen Jing: "The Goguryeo army has 10,000 people each in Xincheng and Liaodong in Liaoshui, and has stored a large amount of grain and grass materials, and the logistics supply of the Liaodong army must come from these two military cities, but it is also more than 400 miles from the nearest Liaodong City to Liucheng, and the journey is too long, so I think their supplies will not be transported so far, and they must use a transit station in the middle." ”

Pei Xingyan drew a circle on Yancheng, "Yancheng is just halfway, then the logistics supply of the Liucheng Goguryeo army is sent from Yancheng, for you, you need to cut off three supply lines, Liaodong City to Yancheng, Xincheng to Yancheng, and then from Yancheng to Liucheng, do you understand what I mean?" ”

"Humble position, understand what the general means!"

Pei Xingyan nodded, "Give you 5,000 cavalry, you can arrange it yourself, but be sure to cut off all three supply lines for me." ”

That night, the 5,000 cavalry left the grassland of the Xi tribe and galloped towards Yancheng.

On the one hand, the distance is far away, there are more than 480 miles from Xincheng to Liucheng, and it is extremely inconvenient to carry baggage, on the other hand, all kinds of siege weapons are in Liaodong City, which was originally attacked by the army of Yizhi Wende, and Xincheng only has a small number of siege ladders, no more than a hundred.

In addition, there is another extremely important reason, that is, his father Yuan Taizuo reconciled with Yizhi Wende, and Yizhi Wende promised to give him logistical support, then their supply route became Yancheng to Liucheng, which was only one hundred and twenty miles apart, and the supply team could reach Liucheng in one day and one night, which greatly shortened the transportation distance.

It was also with Yancheng as logistical support that Yuangai Suwen minimized the burden and facilitated the march of light troops, they only carried the necessary tents and half a month's food, and in terms of siege weapons, they only brought eighty siege ladders.

Yuangai Suwen did not rush to attack, he observed outside the north city for three days, his spies found a trap outside the north and south cities at night, which was actually quenched with highly poisonous sharp bamboo sticks, which scared Yuangai Suwen into a cold sweat, if he attacked rashly, the soldiers would inevitably suffer heavy casualties, and Yuangai Suwen dispelled the idea of attacking immediately.
