After Luo Cheng led his army to pass under the city of Tongding, he headed northeast.

A large river was blocked in front of it, but the water of the Taotao River had already been frozen into ice, and it became a smooth road connecting the east and west.

The fourth child looked at the big river and suddenly wanted to recite a poem.

"The wind is sluggish and the water is cold, and the soldiers are gone········" Before the poem was finished, Luo Cheng kicked him off the sleigh, which was too unlucky.

But standing in front of this glacier, it really makes people feel a little small.

"It's a big river." The fourth child got up from the snow and exclaimed by patting the snow on his body.

Luo Cheng looked at the glacier in front of him and the iron horse behind him, and couldn't help but think of a poem.

"Lie down at night and listen to the wind and rain, and the iron horse and the glacier fall into a dream."

"Good poetry." Wei Laodao got down from a climbing plow behind him with his beard and praised loudly. "Is there anything else in the back?" He didn't expect that Luo Cheng, who was a young man's enemy, would actually recite poetry. Wei Zheng is a little well-read, and he claims to have read a lot of poetry books, but he has never heard this poem, but it sounds very domineering.

Luo Cheng thought about it, didn't remember the second half of the sentence, and finally thought of the other two lines of poetry, so he said casually, "But make Longcheng Feijiang, don't teach Hu Ma to do Yin Mountain." ”

Wei Zheng first thought of Luo Cheng's Longcheng Feijiang wine, a bucket of thousands of dollars. But I was stunned for a moment, and immediately realized that this word was placed here, and it was really more suitable. The four sentences are combined, very heroic and domineering. Thinking of Longcheng Feijiang's wine, and listening to this poem again, Wei Zheng became more and more sure that these four poems were written by Luo Cheng.

"Good poetry, good poetry."

"Good poetry of fart, we are carrying a sword and sandwiching our heads on the waistband of our trousers to beg for our lives to earn military merits, but we are not here to spend our lives." Luo Cheng scolded with a smile to himself.

Changshi Hou Mo Chen Yi came over with a smile, "I think this poem is good, it is worthy of the poem made by our vanguard general of ten thousand enemies, full of sword killing, there is a sword that defies the heroism of millions of beards, not those disease-free moaning songs made by those Jiangnan broad-robed and well-dressed children." ”

Since the Wei, Jin, Southern and Northern Dynasties, the mainstream of poetry is still the so-called palace style poems, glamorous poems, such as Chen Houzhu is one of the masters, he has done a poem called Yushu backyard flower, which is typical, the rhetoric is gorgeous, and the sound of millet is millow. Later, a great poet in the Tang Dynasty made a poem satirizing him, writing that the merchant girl did not know the hatred of the country, and she still sang the flowers in the backyard across the river.

Hou Mo Chen Yi did not praise Luo Cheng, but really felt that this poem was good and wrote it well.

"Don't brag about me, if you blow it again, I really want to be fluttering, thinking that I am a great poet, maybe I will take off this armor and military robe, and then go to Daxing to be a poet."

Qi Fatzi smiled and patted his ass, "General, you are not only a poet immortal, but also a war saint, you are a poetry and a battle." ”

"Fart, don't talk nonsense, this big river is ahead, let's confirm the route again."

"What is there to confirm, didn't the general already say the plan before, and all our generals and colonels nodded in agreement, there is nothing to hesitate about, let's go straight to Xuansu City."

Xuanfu City is the site of Xuanju County, one of the four counties of the Han Dynasty in history, but today's Xuanfu City is not the original Xuanju County City, just like the Xiangping City that is being built now is not the original Xiangping City of the Han Dynasty.

The Han Dynasty set up four counties in eastern Liaodong, and Xuansu County was east of the Liao River, north of the peninsula, and north of the Yalu River.

It is almost that in later generations, Liaoning belonged to Liaodong County, Jilin belonged to Xuansu, and the Korean Peninsula belonged to Lelang and Daifang.

The Xuansu County Administration Office was originally rented in Fu, that is, Hamxing in Later Korea, and later moved to Goguryeo County, and later Xinbin, Liaoning, ruled Fuyu, Goguryeo and other ethnic groups.

Later, it moved to the vicinity of Shenyang.

Later, the Goguryeo people continued to rise and gradually occupied the land east of the Liao River, and Xuanju County naturally ceased to exist.

The current Xuanyu City is in the west of Shenyang in the later generations, only 60 miles away from the Liao River, and only 80 miles away from Tongding City.

Because it is located on the plain of the lower reaches of the Liao River, it can be said that it is a small mountain city with relatively little danger to defend.

Forty miles southeast of Xuansu City, there is Gaimu Mountain City, and one hundred miles northeast, there is the largest strategic node fortress new city of Goguryeo people in this area.

Compared with Xuansu City, the new city can be much larger, this is a city that has a history of more than 300 years, since the Wei and Jin dynasties, experienced more than ten wars, the new city was established on the Gaoer Mountain in the northeast of Fushun in later generations, by the east city, the west city, the south acropolis, the north acropolis and the southeast corner of the three acropolis formed an organic war fortress defense body, the perimeter of the city wall is eight miles, there are three gates of the north, east and south, condescendingly, guarding the traffic artery of the north bank of the Hunhe River.

This fortress is actually the main transportation route from the Liaohe Plain to Northeast Liaoning and the Korean Peninsula.

After all, the Liaohe Plain is a flat river, but to the east, there are undulating mountain ranges, and there are only a few holes running through them, and the Goguryeo people rely on these mountains to establish mountain cities in those holes.

Except for Liaodong City, which is a large flat city built on the plain, most of the other cities on the Liaodong defense line are mountain fortresses like Xincheng, and there are more than 200 of them.

If the Sui army wanted to fight to Pyongyang, it had to pass through these cities by land.

Of course, the Sui army can also bypass it, but if it bypasses, it has to worry about these Goguryeo troops who are defending in danger, and they may kill down the mountain at any time to intercept the transportation line of heavy grain and grass, and be careful of being blocked to retreat.

But if you really want to fight, these mountain cities are very dangerous, and they have many mountain cities, which are actually divided into several strategic defense clusters, which can support each other. The casualties in attacking the fortified positions are certainly large, there are fewer soldiers, and it is impossible to fight, and there are more soldiers, and the logistical pressure is greater. The Goguryeo people made it clear that they wanted to exchange space for time through these defense groups, and finally use small and large to withstand the conquest of the Central Plains Dynasty.

Luo Cheng is not a reckless horseman.

He still has a relatively clear sense of the overall situation, especially since history has long told him about the strategy of the Sui and Tang dynasties to conquer Goguryeo, so he knows which method is more effective, and knows which Goguryeo people's killing moves are more powerful.

Not to mention that he has 12,000 people, even if it is two or three times more, Luo Cheng does not dare to fight the new city.

Unless he has ten times as many soldiers, it is possible.

However, Xuansu City can still fight a dozen.

Xuansu is just a small city, although it is also built on the mountain, but after all, the mountain is low and the city is small, although there are mountain cities around, but they are far away.

The nearest is the city of Gaimu, forty miles to the southeast.

"The snow is so heavy, I guess the Goguryeo people didn't expect us to kill it at this time."

Luo Cheng looked at the sky, it was still early.

"Cross the river and rush to Xuanyu City before dark."

After crossing the Liao River, it is only sixty miles away from Xuansu City, and with the sleigh climbing plow, it can still be reached before dark.
