Bogoukou is located in the Yalu River, that is, the lower reaches of the Yalu River in later generations, very close to the mouth of the sea, and the terrain here is dangerous, the Yalu River is also wide enough, and it is the traffic artery from Liaodong to Pyongyang, so as early as two hundred years ago, the Goguryeo people built a strong city pass here, that is, Bogoukou.

Originally, there were more than 30,000 Goguryeo elite soldiers stationed here at Bogoukou, but before Gao Yanshou supported Anshi City, he almost transferred the elite soldiers in the rear, after all, Goguryeo at that time still reported some extravagant hopes, hoping to block the Tang army outside Anshi City, so the defenders of Bogoukou also transferred 20,000, but they did not expect Gao Yanshou's 150,000 troops to be completely annihilated, which also made Bogoukou only 10,000 defenders left, and it can be said that the troops are very empty.

After the fall of Anshi City, the Tang Army will definitely send troops to attack Bogoukou, and then it will come to Pyongyang City, and although Quangai Suwen is desperately gathering troops, he can only use 50,000 troops now.

Therefore, Quangai Suwen is now also facing a very difficult choice, either to send the 50,000 troops to Bogoukou and rely on the danger of Bogoukou to resist the Tang army, or to leave these 50,000 troops and use the strong walls of Pyongyang City to resist the Tang army, after all, the walls of Pyongyang City are much stronger than the passes of Bogoukou, but there is a plain around Pyongyang, and there is no danger to defend at all, so it is not as good as Bogoukou in terms of terrain.

It can be said that Bogoukou and Pyongyang City have their own advantages and disadvantages, if the troops were sufficient before, Quangae Suwen would definitely defend both, but now the troops are empty, and if one is defended, the second cannot be defended, for example, he sent all his troops to Bogoukou, in case Bogoukou falls, then Pyongyang City will be like a woman stripped naked, and the entire Goguryeo will no longer have the possibility of turning over.

It is precisely in consideration of the above problem that Quan Gai Suwen did not sleep almost all night, and when it was early in the morning, he simply got up from the bed, and then went to the study to open the map, carefully check the terrain around Bogoukou and Pyongyang, and by the way compare the advantages and disadvantages of the two places.

When it was almost dawn, Quan Gai Suwen finally slapped the table and made a decision, and immediately opened his mouth and instructed outside: "Summoning boys and men to come in!" ”

Quan Gai Suwen has a few people who are most trusted, the former Gao Yanshou and Gao Huizhen are also among them, but with the surrender of the two of them to the Tang Dynasty after the defeat, this makes Quan Gai Suwen also angry and hateful, and even feels that these outsiders are not trustworthy, so he began to focus on cultivating his son, among which his eldest son is called Quan Nan Jian, and the second son is called Quan Nanjian, both of them are also adults, and their abilities are quite good, so now they have become the most trusted people of Quan Gai Su Wen, and they usually try to tell their two sons to do whatever they want.

"Father!" After a while, I saw two young people walking into the study and saluting Quan Gai Suwen, among them, the one on the right was of medium stature, fair skin and appearance, and the young man on the left who was burly and very similar to Quan Gai Suwen was the second son, Quan Nanjian.

"Well, how are the troops and supplies prepared?" Quangai Suwen looked at his two sons at the moment, and then he asked, the military and political power of Goguryeo was captured by Quangai Suwen, but he couldn't do everything himself, such as recruiting troops and organizing logistics before, he handed over to his two sons to take charge of it.

"Father, the dispatch of materials is very smooth, after all, there are a lot of materials stored in the city of Pyongyang, but the population in the city is also large, and now all the materials are prioritized to supply the army, and the materials in the city are somewhat shortage, according to my estimate, the materials in the city can only support for two or three months at most, and it will be winter at that time, so it is best to find a way to mobilize some materials from other places." I saw that the spring boy was the first to speak at this time.

Quan boy likes to read, especially the Central Plains culture is very admired, and he used to invite a gentleman who is proficient in Confucianism to teach him to learn Confucianism, and even at the age of fifteen, when the Tang Dynasty and Goguryeo still had some contacts, so he once traveled to the Tang Dynasty in person, and after he came back, he also helped his father Quan Gai Suwen deal with some government affairs, so now the affairs of government affairs are generally handled by him on behalf of Quan Gai Suwen, of course, some things still need Quan Gai Suwen to nod.

"Now we are at the moment of life and death, for us, the most important thing is to repel the attack of the Tang army, so that we have time to think about other things, so boy, don't think about other things, just fully support the army!" Quangai Suwen said in a deep voice at this time, how could he not know that the materials in the city were tight, but if he couldn't repel the attack of the Tang army now, then the entire Goguryeo would be gone, so what else to think about?

"What my father said is that I have been practicing the recruited army during this time, although the 50,000 army is not as elite as before, but after this period of training, it is almost the same, and we are defending the city, with the strength of Pyongyang City, I am afraid that the Tang Army does not have an army of 200,000, I am afraid that it will not be able to defeat Pyongyang City!" Quan Nanjian also nodded when he heard his father's words, and by the way, he also praised the results of his military training.

"Second brother, don't be too confident, the defense of Anshi City is not much worse than Pyongyang, but it still fell in the end, and as far as I know, the firearms of the Tang army are extremely sharp, even the strongest city walls can be blown up, and when there is no city wall, what will we do to resist the Tang army?" At this time, the spring boy retorted.

"Big brother, you also think too highly of Anshi City, how can a small city in a mere place compare with our capital city of Goguryeo for hundreds of years? And there is a father himself here, do you think that your father is not as good as Yang Wanchun? Quan Nanjian spoke again with a thorn in his words at this time.

Although they are brothers of the same mother, both of them are adults, and their abilities are not bad, especially Quan Nanjian is very ambitious, and has always wanted to replace Lu Nan to take over his father's position, so as to become the first person in Goguryeo, so there are also many contradictions between their brothers, but they are usually pressed by Quan Gai Suwen, so it has not yet reached the level of completely tearing their faces, but some of the battles that are usually open or dark have already begun.

"Okay, now that the enemy is present, if your brothers can't work together, then what can we do to defeat the Tang Army?" At this moment, Quan Gai Suwen slammed the table and said angrily, usually he is very tolerant of the fight between his two sons, but now that the enemy is present, he has no patience to let the two sons divide the superiority.

Seeing that his father was angry, the two brothers Quan Nan and Quan Nanjian immediately didn't dare to speak again, and at this time, Quan Gai Suwen looked at the two sons again, and then said slowly: "Yesterday I thought about it all night, and finally made a decision, I will personally lead the troops to garrison Bogoukou!" ”
