Bei River Estuary.

The camp that once came to settle after the defeat of the Hu'er army has now become the camp of the Fifth Army of the Left.

100,000 young and strong young people of Goguryeo brought countless money, grain, cloth, silk and ordnance, and in a short period of time, rammed earth for walls, dug ditches for rivers, and built a city of six miles around the mouth of the river.

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

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

Although the Left Fifth Army had cities, food, ordnance and money, it was still in danger, after all, it could not find a single friendly army in all directions.

"Where the hell did you die?"

The fourth scolded angrily.

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

"Fifth brother, the little cub finally couldn't help it, and he led the troops to press over. 50,000 horses, only ten miles away from us. It's already in formation, and it seems that it wants to fight us. ”

Luo Cheng knew that the opposite was the son of Ezhi Wende, Oji Ieyasu, and it was said that the eldest son of Ezhi Wende was very capable of fighting, very brave, and had a bit of his father's demeanor. But after all, he was only in his early thirties, and Luo Cheng wouldn't believe how powerful he was.

"I don't know where Yizhi Wende wende, if he comes in person, we can find him to avenge the defeat of the Eighth Army."

In the last battle, the Sui army had no way to retreat, and in the face of the Goguryeo army that pressed over, everyone behaved relatively calmly. First, the Goguryeo army only has 50,000, and second, there is no way to retreat anyway, just fight them. Moreover, the camp city that the Left Fifth Army has urged the Goguryeo youth to build these days is not impregnable, but it has a city to rely on, and it is always good.

"If Wende comes in person, he will definitely not fight with us here, and he will choose to besiege rather than attack at most."

"Why?" Wang Tiehan of the White Horse asked.

"Because although we have our backs to the sea and seem to have nowhere to retreat, in fact, the Beijiang River and the sea have become our two barriers, and it is impossible for the Goguryeo people to attack us from behind us and from the sea, so we don't have to worry about the enemy on our backs."

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

Wang Tiehan smiled, "But since we have enough food and weapons, why do we still say that besieging but not attacking is the best policy?" ”

"No matter how much food is fully equipped, we are also alone, or are we alone on the overseas peninsula thousands of miles away, as long as we drag it out, it will be winter immediately, not to mention that there will be no reinforcements by land, even if there will be no reinforcements by sea, and when there is no help in this winter and spring, they will fight calmly, wouldn't it be better?"

"Indeed."

That little general will undoubtedly not think about such a long-term, or he can think of it, but he just doesn't want to wait. Faced with the more than 10,000 Sui troops who razed Pyongyang and captured the king alive, he wanted to annihilate them immediately.

Fifty thousand against more than 10,000, Xiao Yizhi seems to feel that he has a great chance of winning.

Standing on the city tower, the distance of ten miles is actually not too far, and on the Jiangkou Plain of Pingchuan, dense black spots gather.

"Get ready for battle."

Luo Cheng ordered.

"What are you going to do next after you think about it?" ”

"I've asked people to look for sailors, along the coast, and I don't believe that the sailors who came to protect 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. ”

"Go back to the Central Plains? Can't you join the naval division to counterattack? We have already razed Pyongyang, and with the cooperation of the sailors, it will not be difficult to gain a foothold here, right? ”

"It doesn't make sense." Luo Cheng shook his head.

At the beginning, Luo Cheng decided to raze Pyongyang and then evacuate, instead of sticking to Pyongyang, the biggest reason was that when the Eighth Army was defeated, it was impossible to have reinforcements from the land direction.

Although the sailors come from the sea, the coastline of the Yellow Sea and the Bohai Sea will freeze in winter, and it is not easy to rely on the sailors who sail along the coastline to come to Pyongyang, and they have to rely on the monsoon to sail and avoid the winter freeze.

When winter comes, the land route is blocked, but they remain on the Korean Peninsula, even if they defend the strongest city, they will eventually have to face the crazy counterattack of the Goguryeo, and they will not have reinforcements at all.

No one wants to face this situation.

Therefore, when the Eighth Army was defeated, although Luo Cheng fought towards Pyongyang, he was actually just looking for an optimal retreat plan. He never thought that he would have to rely on his own strength to save the defeat of this expedition to Liao.

Whether or not to capture Pyongyang is actually in the benefit of the overall situation.

Even if Pyongyang is broken and Gao Yuan is captured, it is just to make the failure of this Eastern Crusade look a little better and earn some face for Yang Guang.

If it is not the Sui Dynasty now, but the Song and Ming dynasties, then maybe it will be different. After all, navigation technology and shipbuilding technology have made great progress at that time, from Donglai to Pyongyang, direct shipping is actually only two or three days, and even do not need to rely on the monsoon to be able to sail in the deep sea, before the winter freeze, can still continue to transport a large number of soldiers and horses to replenish reinforcements, so that it is possible to really survive the long winter and spring.

Not now.

The key to Duan Wenzhen's original plan for the emperor was to advance by land and water, and the naval division and the Ninth Army by sea would converge under Pyongyang, break Pyongyang and base it, and then sweep the surrounding area, relying on the strong city of Pyongyang, and then seize food and supply the army on the spot, then hundreds of thousands of troops could completely sweep the south of the Yalu River before winter, even if there were a few strongholds left, there was no need to worry.

If Pyongyang is broken, the defense of Goguryeo in Liaodong will face the dilemma of being attacked by the enemy on the back of the abdomen.

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

If you make a mistake in one place, you will make a mistake everywhere, and in the end, the chain reaction will collapse.

"Where the hell is the sailor?" Heiye couldn't help but sigh. According to his brother Luo Cheng's plan, it is impossible for them to continue to stay here, but if they can't find the water master, they can't go home.

"We had to continue searching, but we couldn't, so we had to go all the way south to Baekje or Silla to take refuge. But I don't want to go south unless it's a last resort. ”

The fourth brother came over, "Who wants to run further south, we brought out so much money and materials from Pyongyang City, we can't just throw them here, right?" Lao Tzu grabbed these, but it was hard work. ”

"The Goguryeo people are attacking!"

Someone chanted in the distance.

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

Countless Goguryeo people surrounded them like ants.

Luo Cheng just looked at it coldly, not panicking at all.

Although I was already a little tired of such a meaningless battle, since they were besieging it, let's fight.
