The seventh year of Daye, summer.

Luo Cheng led his troops to the east with the First Left Army, leaving Zhuo County, passing Yuyang County, Beiping County, passing Lulong, leaving Linyu Pass, and entering Liucheng County, western Liaoning.

Move forward between mountains and sea.

The road we walked under our feet was the road we walked by Yang Liang, King of Han in the 18th year of Kaihuang, General Wang Shiji and Prime Minister Gao Bing and others, leading 300,000 Eastern Expedition Army.

The march is actually boring.

I get up at five o'clock every day, make meals after the rush, and after dinner, I set off for a journey. When it was dark, I stopped marching, set up camps, and rested for a night to continue marching.

The First Army followed the Second Army, and the two armies were forty miles apart.

This happened to be a day, and the 10,000 Second World War soldiers, 8,000 auxiliary soldiers, and 30,000 civilians all had their own distances.

A cavalry regiment opened the way in front, a cavalry regiment was at the end of the back hall, and two other cavalry regiments protected the two wings in the middle. The four infantry regiments of eight thousand were also divided into three parts, front, middle and back. Luo Cheng's two thousand regiments were more well-equipped than other sect groups, so Luo Yi arranged in front.

They walked ten miles away from the vanguard cavalry, and ten miles away from the central infantry and baggage behind them.

After leaving Linyu Pass, the more you go east, the harder the road will be.

Especially when summer is approaching, there are many winds and rains, and often encounter heavy rains, delaying the progress. Sometimes the road is washed away by continuous heavy rain.

So when it rains heavily, I had to stop marching and set up camp.

If the road is destroyed, you will have to open the road across the mountain and build a bridge across the mountain.

Fortunately, Luo Cheng's vanguard group also brought two civilians. They were mostly responsible for the hard work, and they had no worries about food and supplies.

In this way, he set out from Lu County in early May, and in mid-July, Luo Chengcai finally arrived at the destination of the march, Huaiyuan Town, western Liaoning.

Huaiyuan Town is Huaiyuan County, which is located in the east of Liucheng County. Because it is the farthest place actually controlled by the northeastern border of the Great Sui Dynasty and is on the west bank of the Liao River, it has long been designated as the outpost for this Liao battle.

Huaiyuan therefore set up a military town, along with Luhe Town beside the Bailang Water and Linhaidun beside the Bohai Sea, becoming the three fronts of the Great Sui Dynasty's Eastern Expedition.

When Luo Cheng was fine, he also studied the military maps of western Liaodong. He is now on the front line. Luo Yi, the first army general, is his uncle, so he has a lot of resources and can also access these confidential military maps.

Luo Cheng discovered that Huaiyuan Town was actually the later Ningyuan City, while Luhe Town was the later Jinzhou. As for Linhaidun, it was Huludao.

Anyone who has read the history of the Ming Dynasty and the history of the War of Liberation knows how important the three places of Ningyuan, Jinzhou and Huludao are in western Liaoning. Isn’t this the Guanning defense line that was defended in the late Ming Dynasty.

Liaoxi County was also called Yingzhou in the early Sui Dynasty. Later, Yingzhou was changed to Liucheng County, and Yan County and Liaoxi County were divided into two counties in the east.

This is an important military town outside the Central Plains Dynasty for hundreds of years. If there were no Yingzhou, the Goguryeo would have fought the Liaohe River long ago and even expanded to Shanhaiguan.

From Linyu Pass, which is the Shanhai Pass in later generations, to Liaodong, there are two main roads, one is the Bailang Water Ancient Road, which marches in the valley along the Bailang Water River Valley, and arrives at Yingzhou. This road is relatively old, but it is also difficult to walk, and is all in the mountains.

And there is another way, which is the Liaoxi Corridor that was repeatedly fought for in the Ming and Qing dynasties, moving along the coast.

That is, Guanningjin's front line.

After leaving Linyu Pass, pass through Linhaidun, Liucheng Town, Luhe Town, and Huaiyuan Town, and directly to Liaoshui.

Even when the Bohai Sea is not frozen, you can directly sail from the pass or even along the Yellow River estuary to Linhaidun Port. This will greatly improve the capacity of transporting and supply for food, supplies.

“Our goal is here.”

Luo Cheng pointed to a point on the map and pointed there, "Look, now my Great Sui Dynasty is committed to conquering Liao, and I have sent millions of troops. I must have fought across the Liao River and pointed at Pyongyang. However, the Goguryeo people still occupy a piece of land on the west bank of our Liao River. This piece of land is a thorn, stuck in our throats, so before our army crosses Liao, we must conquer this place first."

The fourth brother looked down and saw that Luo Cheng was referring to the north of Huaiyuan Town.

"Isn't this the west bank of the Liao River? Why did the Goguryeo people even occupy our west bank?"

"What's the matter? The current capital of the Goguryeo people was Pyongyang City. In the Han Dynasty, it was also a land of one of the four Han counties in our Central Plains. Now it is also a royal city of others, and even the entire Liaodong Peninsula was ours. But over the years, the Goguryeo people took advantage of the turmoil and chaos in the world and eroded westward step by step. In the early years, they even surrounded Yingzhou, so sooner or later they would fight this battle."

When the Great Sui Dynasty conquered Liao Dynasty, the Goguryeo people were also prepared for it.

On the east bank of the Liao River, they built a hard thousand-mile defense line, supported by the wide Liao River, and established fortresses and fortresses such as Liaodong City, Xincheng, Baiyan City, and Gaimu City in Hedong. At the same time, they used the mountainous areas behind the Liaodong Plain to build many mountain cities. Relying on several major cities such as Liaodong City, they formed several huge fortress defense clusters, and then joined forces to try to block the Sui army west of the Liao River.

"Two hundred miles northeast of Huaiyuan Town is Wuliluo City on the west side of the Liao River. Don't underestimate this place, it's very important."

"Why?" Lao Si asked in confusion.

"Because the Liao River is vast, especially in the lower reaches of the Liao River, the river has not been passed through for hundreds of years, so it has become a huge river area that is hundreds of miles wide, with swamps everywhere. Especially in summer, when the rain is frequent, it has become a marina country, difficult to pass through, dense water networks, and ubiquitous marina beaches, becoming a natural uninhabited area that is difficult to cross."

But to the north, the Liao River is much narrower. Several Liaodong rivers, including the Xiaoliao River and Daliang River, all flow into the Liao River in this lower reaches, and are far away from the sea. Therefore, it can be said that this river channel is narrow, the river water is gentle, and the two banks are flat, making it an excellent crossing location.

Another thing is that the Wuliluo City is hundreds of miles upstream of Liaodong City, so the defenders of Liaodong City, the first military fortress in Liaodong, are far beyond the reach of this place, and the counterattacks encountered when crossing the river will not be so strong.

"Take Wu Liluo on the west bank, and then you can build a floating bridge by the river and the army crosses the river."

Compared to Huaiyuan Town directly facing east, this Wuliluo seems very important.

There are actually many Wuliluo City, similar to Dunburg.

"So the mission of our First Army is not to garrison Huaiyuan Town, but to fight Wu Liluo?"

Luo Cheng nodded, "I guess, not only our first left wing army, but also the second army are going to fight Wu Liluo. Don't underestimate this city. This is the first place to be captured on the chessboard of Liao. Two armies are 40,000, and there are enough troops. The army is still gathering in Zhuo County. It is estimated that the people of Goguryeo thought we would officially send troops next year, so we were caught off guard by killing them."
