After the tentative siege failure, the Goguryeo army stopped all attacks and entered a confrontation. On the one hand, although they had not yet cracked the defense skills of the Sui army, on the other hand, it was even more important. All the eighty siege ladders they carried were destroyed by the Sui army, making them unable to siege the city.

At night, Yuan Gaisuwen walked to the door of the tent and stared at the dark city wall three miles away. His heart was heavy. A tentative attack made him realize that they had thought it was too simple to capture Liaodong.

Liucheng's defense was obviously carefully prepared. Tens of thousands of Khitan troops could not break through. Can 30,000 of them break through this strong city? The answer is obviously very difficult. Maybe they have a little chance, but this opportunity is too slim unless the Sui army made a big mistake, unless his soldiers can get into the city.

Yoon Gaisuwen sighed. No matter what, he had to do his best. Goguryeo had been preparing for this expedition for more than a year. He could not give up just because he encountered difficulties temporarily. He needed to wait patiently for the opportunity.

At noon on the third day, near an abandoned official road about 70 miles east of Liucheng, a Sui army scout was resting and eating dry food by a stream not far from the abandoned road. This was a small scout team with only ten soldiers, led by a fire chief. Their mission was to monitor the movements of the Goguryeo army near the official road. There were ten other scout teams carrying out the same task as them.

They just discovered in the morning that there was an official road twenty miles south of the official road. Although this official road has been abandoned for many years and looks very dilapidated, it can still be used to walk on a large cart, and it is hidden in the dense woods and is difficult to find.

Huo Chang'er's name is Liu Shun'er. He is only in his early twenties. The young man is very smart and capable. He sits on a big rock by the stream, gnawing on dry food while checking the map in his hand.

"I'm still given by the government. There is no such road on it. I don't believe they don't know. After all, they are just 'lazy'. At least they should mark it and write the three words 'abandoned'. Do you think so?"

Liu Shun'er's tone was full of contempt for the Liucheng County government. He said to another soldier: "Dazhi, you are from Liucheng County. Do you know this abandoned official road?"

The soldier named Dazhi scratched the back of his head and said, "Maybe he knew it, but I forgot."

"I am another local who knows nothing. Even I, a native of Qinghe County, know much more than you."

Everyone laughed, "Huo Chang, stop complaining, eat quickly!"

"Of course, this piece of dried meat is harder than a stone, and it almost knocked off my teeth."

Liu Shun'er complained again, throwing the jerky meat in her hand to another veteran, "I'll give it to you."

"Spit! It's all your saliva, why don't you throw a piece of gold to me?"

"Dream! It's still gold, there's no yellow mud."

At this time, a soldier who was watching outside rolled and crawled over, "Captain of Fire, there is an enemy!"

Everyone stood up in fear, and Liu Shun'er asked, "How many people are there?"

"I saw more than a hundred people, all of them were cavalry, and I don't know the others."

Liu Shun'er waved his hand and everyone calmed down and held their breath. After a moment, Liu Shun'er turned over and said, "Everyone comes with me."

Everyone got on their horses and followed the fire to the north.

Soon, a huge convoy of ox carts appeared on the abandoned official road, with more than a thousand ox carts, carrying grain and a large number of siege ladders slowly walking on the abandoned road. About three thousand guards were followed on both sides. This was a supply grain team coming from Yancheng. They did not follow the main official road, but walked on the abandoned official road. Goguryeo had been investigating for many years to seize Liaodong. They knew that this abandoned official road could secretly send grain supplies to the Goguryeo camp in Liucheng.

At this time, in the dense forest several miles away, ten Sui army scouts were nervously and excitedly watching the convoy in the distance, and they accidentally discovered the target.

Liu Shun'er thought for a while and whispered: "Dazhi took five brothers to go back to report to the general, and I will continue to follow the convoy."

Several subordinates nodded, "Be careful, Huo Chang, don't be hunted by the enemy's spies."

"Go away! I won't come to my door."

Six Sui army scouts turned their horses and ran northwards. Liu Shun'er also led the remaining men to run in the opposite direction of the grain team.

In fact, the Sui cavalry team led by Chen Jing was on a grassland north of the official road. Pei Xingyan gave him the task not only to cut off the supply line between Yancheng and Liucheng, but also to cut off the grain transportation between Yancheng, Liaodongcheng and Xincheng.

Chen Jing divided his troops into three groups. He sent one thousand cavalry to the new city of the Liaohe River and the other side of the Liaodong City to destroy the floating bridge built by the Goguryeo army on the Liaohe River. He himself led three thousand cavalry to ambush near the official road east of Liucheng, waiting for the supply convoy coming from Yancheng.

Chen Jing had been waiting for three days, but there was still no movement. Most of the dry food he brought was given to the two thousand brothers who went east to Liaohe River. He didn't leave much dry food. If there was no movement today and tomorrow, he would have to return to the camp to replenish the food. This made Chen Jing very distressed. He didn't know where he had a problem. In fact, he also suspected that the supply grain convoy of Goguryeo had taken other roads.

At this moment, a soldier came to report: "Report to General, a team of scouts discovered the food trucks of the Goguryeo army!"

Chen Jing was overjoyed and stood up, "Where are the people?" he asked anxiously.

After a moment, a scout was brought up and knelt down on one knee to report: "Scout Wang Dazhi meets the general!"

"I'll ask you, where is the grain fleet you found?"

"General Qi Bi found it on an abandoned official road, about thirty miles away from here, just south."

Chen Jing stood up and looked south, with a sudden look in his eyes. Sure enough, he guessed that the Goguryeo grain convoy was on another road, which he didn't know about. He asked again: "How many grain trucks are there?"

"The team is very long, about one thousand vehicles, and there are soldiers and guards, all infantrymen. We estimate that about two or three thousand people. Our Fire Chief is still monitoring it."

Chen Jing made a quick decision and ordered: "The whole army gathered immediately!"

Three thousand soldiers extinguished the fire, packed their luggage, and turned over and ran south with the main general.

The Goguryeo General who was carrying food and supplies was a young Duhou named Yang Wanchun. His men had already discovered that the enemy was following him secretly, which made him very worried.

Before he set out, Yizhi Wende told him that the Sui army's cavalry might have entered Liaodong and hid somewhere to ambush their grain team. He repeatedly told him not to walk on the official road and change to the abandoned old road to Liucheng. Once he encountered a powerful Sui army attack, if the army could not resist, he could give up the grain truck and retreat.

Yang Wanchun walked carefully all the way. When he got the spies ahead to find the traces of the Sui army scouts, he suddenly became nervous and ordered the convoy to speed up. He had to arrive at Liucheng before dark.

The grain truck turned a corner and entered a relatively spacious road. At this moment, the earth began to tremble, and rolling yellow dust appeared in front of him. The grain truck convoy stopped one after another. The coachman looked ahead in confusion, but they had not realized that the danger had arrived.

The Goguryeo soldiers were all panicked and instinctively retreated. Yang Wanchun's face was pale, and his hand holding the spear also trembled slightly with the trembling rhythm of the earth.

"It's a cavalry!"

Suddenly, the Goguryeo soldiers in front shouted in fear. The coachmen woke up as if they were dreaming, jumped out of their ox carts, stumbled into the woods on both sides and ran away.

Yang Wanchun quickly judged the number of Sui army's cavalry, at least more than 3,000 cavalry, and their two thousand food-protecting troops were definitely not the opponents of the cavalry. He made a quick decision and said, "Retreat!"

Two thousand soldiers left their food trucks and ran eastward. In just a moment, the Sui cavalry came roaring. Dozens of Goguryeo soldiers were unable to escape. They were stabbed by the cavalry's spear and fell to the ground and died tragically.

Yang Wanchun turned around and saw the cavalry chasing them, less than two hundred steps away from them. In desperation, he shouted: "Retreat into the woods!"

Two thousand soldiers fled into the woods, and the Sui army stopped chasing and withdrew the grain truck. Chen Jing looked at more than a thousand grain trucks, at least ten thousand stones of grain. He was overjoyed that the problem of insufficient food was finally solved.
