Beijiangkou.

The camp where Lai Hu'er once settled after his defeat has now become the camp of the Left Five Army.

One hundred thousand young and middle-aged men from Goguryeo transported countless money, grain, cloth, silk and military equipment. In a short time, they rammed earth into walls, dug trenches into rivers, and built a city of six miles around at the mouth of the river.

There are many enemy towers on the city wall, and there are many arrow towers in the city.

On one side is the river and on the other side is the sea, and in front is a wide plain.

Although the Left Five Army had cities, food, weapons and money, they were still in danger. After all, looking around, they could not find a friendly army.

"Where did this fucking Hu'er die?"

The fourth brother scolded angrily.

Luo Cheng, standing on the city tower, also wanted to curse, but as the commander of the first army, he knew that if he couldn't help but curse, it would only make the other soldiers more anxious. He could only pretend to be detached, as if everything was within his plan.

"Fifth brother, the little boy from Yizhi finally couldn't help it. He led his troops to suppress it. The 50,000 troops were only ten miles away from us. He had already set up a formation and seemed to want to fight us."

Luo Cheng knew that the person who came opposite was Yizhi Ieyasu, the son of Yizhi Wende. It is said that Yizhi Wende's eldest son is very capable in war, very brave, and has a bit of the style of his father. However, after all, he is only in his early thirties, so Luo Cheng would not believe that he is so powerful.

"I don't know where Yizhi Wende has gone. If he comes in person, we can ask him to avenge the defeat of the Eighth Army."

After fighting against the water, the Sui army had no way to retreat. Facing the Goguryeo army that was pressing over, everyone was calm. First, the Goguryeo army had only 50,000, and second, it was impossible to retreat anyway, so just fight them. Moreover, the camp that the Left Five Army urged the young and strong Goguryeo these days to urge the Goguryeo to rush to rush to the camp. Although it is not said that it is indestructible, it is always good to have a city to rely on.

"If Wende came in person, he would definitely not fight with us here. At most, he would choose to siege rather than attack."

"Why?" asked Wang Tiehan, who was in charge of the White Horse.

"Because although we are back to the sea and have nowhere to retreat, in fact, Beijiang and the sea have become two barriers on our sides. The Goguryeo people cannot attack us from behind and on the sea side, so we don't have to worry about the enemy who is behind us."

"Besides, we are defending the city and fighting, and we have enough food and equipment, are we afraid that they will attack the city?"

Wang Tiehan chuckled, "But since we have enough food and equipment, why do we still say that surrounding but not attacking is the best way?"

"If we have enough food and equipment, we are still alone, and we are still on the overseas peninsula thousands of miles away. As long as we drag it, winter will begin soon. Not to mention that reinforcements cannot come by land, reinforcements cannot come by sea. When there is no help in winter and spring, will they fight calmly? Wouldn't it be better?"

"It's true."

The Little Yizhi general undoubtedly would not consider this long-term, or he could think of it, but he just didn't want to wait. Faced with the more than 10,000 Sui troops who flattened Pyongyang and captured the king alive, he wanted to annihilate them immediately.

From more than 50,000 to more than 10,000, Xiao Yizhi seemed to think that he had a great victory.

Standing on the city tower, the distance of ten miles is not far. On the plain river Jiangkou Plain, dense black dots gathered.

"Prepare to fight."

Luo Cheng ordered.

Siye came over, "What should you do next after you think about it?"

"I have already asked people to look for the navy and search along the coast. I don't believe that the navy who came to Hu'er for more than 100,000 people disappeared without a trace. As long as we can find them, we can take a boat back to the Central Plains."

"Return to the Central Plains? Can't we join the navy to fight back? We have already leveled Pyongyang. If the navy cooperates, it will not be difficult to gain a foothold here, right?"

"It's meaningless." Luo Cheng shook his head.

The biggest reason why Luo Cheng made up his mind to razed Pyongyang and evacuate instead of defending Pyongyang was that when the Eighth Army was defeated, it was impossible for reinforcements to come from the land direction.

Relying on navy alone also faces a huge problem, that is, winter is coming soon. Although the navy comes from the sea, the coastline of the Yellow Sea and Bohai Sea will freeze in winter. It is not easy to rely on navigators sailing along the coastline to come to Pyongyang. They have to rely on the monsoon to sail and avoid the winter freezing period.

When winter comes, the land is blocked, but it is still on the Korean Peninsula. Even if you guard the city, you will have to face the crazy counterattack of the Goguryeo people, but they will never have reinforcements.

No one is willing to face this situation.

So when the Eighth Army was defeated, although Luo Cheng rushed to Pyongyang, he was actually just looking for the best retreat plan. He never thought that he would rely solely on his own to save the defeat of the Liao Dynasty.

Whether to conquer Pyongyang or not is actually all about the overall situation.

Even if we defeated Pyongyang and captured Gao Yuan, we would only make the failure of this Eastern Expedition a little better and earn some face for Yang Guang.

If it was not the Sui Dynasty, but the Song and Ming dynasties, then it might be different again. After all, nautical technology and shipbuilding technology have made great progress by that time. Direct flights from Donglai to Pyongyang were only two or three days, and they could sail deep into the deep sea without even relying on the monsoon. Before the winter freeze, they could still transport a large number of troops to supplement reinforcements, so that they could truly survive the long winter and spring.

But it doesn't work now.

The key point of Duan Wenzhen's plan originally formulated for the emperor was to advance water and land, and the navy and the nine armies joined under Pyongyang, broke Pyongyang and occupied it, then swept the surrounding area, relying on the Pyongyang city, and then seized grain supply to the army on the spot. Then hundreds of thousands of troops could completely wipe out the south of the Yalu River before winter. Even if there were a few strong cities left, there was no need to worry.

If Pyongyang is broken, Liaodong Goguryeo will face the dilemma of being attacked from both sides. At that time, the two sides will be attacked, and a battle will be decided.

It's just that the idea is better, and it's too difficult to operate.

If you make mistakes, you will make mistakes everywhere. In the end, the chain reaction will collapse.

"Where is the navy?" Siye couldn't help but sigh. According to his brother Luo Cheng's plan, it was impossible for them to stay here, but if they couldn't find the navy, they couldn't go home.

"We can only continue to search. If it really doesn't work, we can only go south and avoid it to Baekje or Silla. But I don't want to go south unless it is absolutely necessary."

The fourth brother came over and said, "Who would like to run south? We brought so much money and supplies from Pyongyang City, so we can't just throw them here, right? I've snatched these, but I have worked hard."

"The Goguryeo people have started attacking!"

Someone shouted in the distance.

The sound of trumpets on the plains sounded, accompanied by the sound of war drums. Sure enough, the Goguryeo people couldn't help but launch a siege.

Countless Goguryeo people surrounded them like ants.

Luo Cheng just looked at him coldly and was not panicked at all.
