In 37 B.C., the Buyeo prince Jumeng lost a political struggle and fled his homeland to the Han Dynasty Xuansu County, where he established the Goguryeo regime in the city of Sushenggucheng. After that, Goguryeo began to expand in all directions, first annexing the territories of some surrounding ethnic groups, and then launching an attack on Xuansu, Lelang and other places under the jurisdiction of the Han Dynasty after its power grew. However, under the blow of the Han and Wei Empires, Goguryeo suffered a crushing defeat and did not recover for a period of time after that.

However, in the Western Jin Dynasty, many nomadic people outside the Saiwai took advantage of the rebellion of the eight kings of the Western Jin Dynasty and the weakening of the national strength, and successively established several non-Han regimes, among which the Hu tribes led by the Xiongnu, Xianbei, Qian, Qiang, and Di confronted the Han regime in the south, and as the Central Plains fell into turmoil and turmoil, Goguryeo took advantage of the situation to rise rapidly, and in 313 AD, Goguryeo broke through the Lelang County of the Western Jin Dynasty, and the following year, it occupied Obifang County. Subsequently, Goguryeo continued to expand to the northwest, and Bingfeng pointed directly to the Liaodong region. After more than 100 years of hard fighting, after the decline of the Xianbei Murong clan, Goguryeo finally controlled Liaodong in its own hands.

Thus, by the 5th and 6th centuries AD, Goguryeo had formed a powerful state that spanned the banks of the Changbai Mountains and the Yalu River, from Liaoshui in the west, to the Sea of Japan in the east, and across the Liaodong Peninsula and the northern part of the Korean Peninsula in the south. It is no exaggeration to say that at this time, Goguryeo was already a hegemon in Northeast Asia, and many regimes in the southern part of the Korean Peninsula were under the power of Goguryeo.

But then again, the reason why Goguryeo was able to become the hegemon of a region was naturally inseparable from its control over the Liao River Valley.

By occupying the Liaodong region, the state of Goguryeo gained a large amount of fertile agricultural land and strengthened its economic power; On the one hand, it also blocks the communication between other countries and the ethnic groups in Northeast China, while on the other hand, it can accept the human and financial resources from the Central Plains and increase the comprehensive strength of the country; What is particularly crucial is that the Liaohe River valley is easy to defend and difficult to attack, which can effectively enhance its national defense strength.

In short, the Liaodong region is the lifeblood of Goguryeo's survival and development, whether it is military defense or economic construction, it is inseparable from this region, and at the same time, this region is close to the Central Plains and is easy to be affected by the spread of civilization. The terrain is easy to defend and difficult to attack, forming an independent, large-scale, sub-civilized political entity. At the same time, Liaodong is the security guarantee of North China, because since the Wei and Jin dynasties, with the eastward shift of the political center and the transfer of the economic region from Guanzhong to North China, the strategic position of the Northeast region has become more and more prominent, and the stability of this region has become very important. What worries the Sui Dynasty even more is that Goguryeo also has the meaning of chasing the Central Plains.

In 598 AD, the king of Goguryeo led more than 10,000 cavalry into western Liao, and Emperor Wen of Sui immediately ordered Yang Liang, the king of Han, and Shiji, the king of Shangzhu, as the marshal of the marching army, and Zhou Luoyu as the head of the navy, leading an army of more than 300,000 to attack Goryeo by land and water.

Yang Liang, the king of Han, led the Sui army out of Shanhaiguan by land, during the rainy season, the roads were muddy, and the supply of grain and grass was not available. The Sui army by waterway, led by Zhou Luoyu, sailed from Donglae to Pyongyang City, but encountered strong winds at sea, and most of the ships sank. So the land and water were forced to return, and nine out of ten of the dead were killed.

Emperor Yang of the Sui Dynasty naturally regarded Goguryeo as "a thorn in the eye and a thorn in the flesh". Emperor Yang of the Sui Dynasty's henchman was also one of the "five nobles" of the Great Sui Dynasty at that time, Pei Shiju, who knew Emperor Yang of the Sui Dynasty's intentions, so he said: "Goguryeo was originally the fief of the uncle of the Shang Dynasty, and it was a county in the Central Plains during the Han and Jin dynasties, but now Goguryeo does not submit to the Great Sui Dynasty and has become a threatening foreign land. The first emperor had long wanted to recover Goguryeo, but it was unfavorable for the Han king Yang Liang to conquer at the beginning, and now it is the heyday of the Sui Dynasty, which is very suitable for crusading against Goguryeo. ”

Emperor Yang of the Sui Dynasty thought about it and felt that it was very reasonable, so in the seventh year of the Great Cause (611 AD), Emperor Yang of the Sui Dynasty issued an edict to attack Goguryeo on the grounds that Goryeo did not obey the courtesy. Emperor Yang of the Sui Dynasty began to recruit soldiers throughout the country: all the men with military household registration in various parts of the Sui Dynasty who had adult and healthy families had to serve in the military and participate in the crusade against Goguryeo.

"Xiao Sheng, have you seen the conscription notice issued by Yang Guang?" Daddy asked me.

"See, all the healthy men of the military household registration family will participate in the army of the crusade against Goguryeo, no matter how far or near, they will gather in Zhuojun." I went through the contents of the conscription notice.

"Not long after you and Xin'er got married, you will be forcibly conscripted into the army." Dad said angrily, "Yang Guang is really bent on going his own way, he took great pains to build the Grand Canal before, and now he wants to recruit troops to fight against Goguryeo, whether he wins or loses is another matter!" ”

I spread my hands and said helplessly, "What can I do then?" You can't help but do military service. ”

"I have been an official for so many years, and I know some people who are officials in the imperial court, and I also know the squire of the military department, and I still have a deep friendship, I went to beg him to change our family's military household registration to civilian registration, so that you don't have to enlist in the army."

"Is that really good?" I asked, confused.

"Let's go through the back door once, to be honest, I am not optimistic about this crusade against Goguryeo, I think Yang Guang is a little anxious, and the preparation is not sufficient, and Goguryeo has developed rapidly for so many years, with its superior geographical location, and its strength should not be underestimated." Daddy shook his head, "You and Xin'er haven't been married for a long time, you are ruthless on the battlefield, to say something unpleasant, if you accidentally lose your life, what should we do?" ”

"Aren't there many families who also have to face the choice of life and death?"

"I can't control others, I can only manage you." Daddy sighed, "It's really sad that the people of Li have such a king!" ”

With that, Dad began to pack his simple bags and immediately set off for Luoyang to find the squire of the military department.

The conscription notice was issued on the fifth or sixth day, at this time Zhuo County had gathered many men who came to serve in the military, Zhuo County has never been so lively, but the whole atmosphere is still relatively gloomy, maybe they all know this crusade, life and death are not easy to say, of course, the possibility of dying in battle is still a little bigger.

On the seventh day, Daddy finally returned, but his face was full of loss, despair, to be precise. "The squire of the military department has changed." Daddy said sluggishly, "Don't talk about pleading, I can't even see each other, it seems that Yang Guang is determined to crusade against Goguryeo this time." ”

"Dad, it's okay, I'll go to military service, I promise you that you will come back alive!" I was relieved.

"I can't even protect my baby!" Daddy said bitterly, "What a wretch! ”

"Dad, don't say that, I'll come back alive, trust me!"

So, not long after I got married, I was also forcibly conscripted into the army to crusade against Goguryeo, and on the day of separation, Xin'er burst into tears: "You must return safely, I don't want to lose you!" ”

My father and mother also looked at me, and there were old tears on their faces with a few wrinkles......
