"What?" Hearing that his father let him flee to Marudu City after the defeat at Bogoukou, Izumi boy couldn't help but scream in shock, and his face showed an incredible expression, after all, these are not like his father's words?

Goguryeo, like the Tang Dynasty, has more than one capital, in fact, Goguryeo has three capitals, in addition to Pyongyang City, there are also domestic cities and Marudu City, and these two cities are very special, because they are next to each other, the distance is only about four or five miles, and they are interdependent on each other.

In fact, as early as the early days of the founding of Goguryeo, the national capital was not in Pyongyang, but in the domestic city, but later in the Three Kingdoms period of the Han Dynasty, Goguryeo had a war with the Gongsun clan belonging to Cao Cao, and was defeated miserably, not only lost a large area of the country, but also destroyed the royal capital, so the king of Goguryeo at that time fled to Marudu City and established it as the national capital.

Marudu Castle was originally only a military garrison city of the domestic city, built on the Marudu Mountain, the terrain is very dangerous, especially after the destruction of the domestic city, Goguryeo began to build the Marudu Castle on a large scale, and built the city wall according to the mountain terrain, most of the city walls are built with square stones, it can be said that it is extremely strong, and there are water sources, warehouses, fortresses, etc. in the city, which can be said to be an extremely strong fortress.

However, although the city of Marudu is strong, it has been captured twice by the Central Plains Dynasty in history, once shortly after the completion of the construction of the city of Marudu, it was captured by Cao Wei's famous general Muqiu Jian, and also erected a monument to record merit, and later was broken by Murong Huangguang, the king of Yan, since then, Goguryeo moved the king to Pingyuan City, but Marudu City is still retained as one of the royal capitals.

"Don't be surprised, if we are defeated at Bogoukou, Pyongyang City will definitely have no troops to defend, and you will wait for death if you stay here, so it is better to flee to Marudu City, where I have left 5,000 elite soldiers, even if they are not used now, and there are still a lot of grain and grass materials stored in the city, which is enough for you to survive this winter!" Quangai Suwen said with a solemn face at this time, when he reached his position, it was impossible not to prepare a back road for himself.

"But ......"

Quan boy heard his father's words and just wanted to say something, but was interrupted by Quan Gai Suwen waved his hand: "It's nothing, even if I fight to the last soldier, I will never surrender, but our Quan family can't be so broken, when you take your family to flee to Marudu City, although it has been destroyed twice, it has also been repaired over the years, and it is a mountainous area, the terrain is easy to defend and difficult to attack, plus winter is coming, the Tang army will definitely not chase after it!" ”

"But......" Although my father didn't want to hear it, the spring boy still had to say, "But even if we survive the winter, what if the Tang Army still refuses to let us go next year, even if the mountain of Marudu City is high and the water is dangerous, but with only a few thousand people, I'm afraid it won't last long?" ”

Quangai Suwen seemed to be very reluctant to answer this question, only to see him close his eyes painfully at this time, and after a long while, he slowly opened his eyes and said weakly: "If the Tang army still refuses to let you go next year, then surrender, I am already dead by then, and the Tang army should not be wiped out, after all, they still need someone to help them pacify the homeland of Goguryeo!" ”

"Father, although the Tang Army is under the banner of avenging King Rongliu, it may not be ......"

"Okay, I know what you're going to say, but I've made up my mind, so don't say anything about it in the future!" Before the spring boy finished speaking, he was interrupted again by the spring guy Suwen, looking at his appearance, he seemed to dislike what the spring boy wanted to say, which made the spring boy sigh secretly, and he didn't dare to say anything at the moment.

Three days later, Quan Gai Suwen led an army of 50,000 to leave Pyongyang City, Quan Nanjian also accompanied him, and only Quan Nanwen was left to manage this side of Pyongyang City, and there was also a logistics supply, after all, Quan Gai Suwen and they had to rush to Bogoukou as soon as possible, so the materials they carried were also limited, and the rear all needed Pyongyang to supply.

After sending his father away, Quan Nan also began to secretly prepare for the retreat, which was also discussed by him and Quan Gai Suwen, he could stay in Pyongyang, but just in case, his son needed to be sent to Marudu City, so as not to have any accidents, so that their Quan family could not even keep a bloodline.

However, with the departure of Quangai Suwen, there began to be some undercurrents in the city of Pyongyang, after all, Quangai Suwen killed King Rongliu before, which made many people very dissatisfied with Quangai Suwen, and before Quangai Suwen calmed down the domestic turmoil, the Tang Dynasty came in, so some people loyal to King Rongliu in Goguryeo also secretly colluded.

In the past, Quangai Suwen was in Pyongyang City, but no one dared to make any changes, but now as soon as Quangai Suwen left, these people loyal to King Rongliu began to act secretly, before they were at most sending some information to the Tang Army, but now these people have begun to prepare some practical actions, and may even seize control of Pyongyang.

In addition, it is worth mentioning that Gaozang, who was put on the throne by Quangai Suwen, is not a fuel-efficient lamp, before he was obedient to Quangai Suwen, in fact, he has always been unwilling to be a puppet in his heart, so after Quangai Suwen left, he also became less obedient, and even secretly began to contact those who were loyal to King Rongliu, after all, he was the nephew of King Rongliu, and it was natural to inherit the throne.

In the face of this kind of chaos in Pyongyang City, Quan Nan couldn't help but have a headache, especially when Quan Gai Suwen took away 50,000 troops, and the defenders of Pyongyang City only had seven or eight thousand people left, and it was still an army that was put together from all over the world, and it was already very difficult to maintain law and order internally, and if there was another invasion by foreign enemies, I am afraid that he would have to surrender the city.

However, as the so-called fear of something, when Quan Nan was busy dealing with the chaos in Pyongyang City, he never dreamed that on the open sea on the west side of Pyongyang City, the Tang army fleet set sail again after rest, and came to a port in Goguryeo in just one day.

As the warship docked at the port, Su Dingfang also immediately ordered his soldiers to get off the ship, and transported the horses and materials off the ship.
