The western and southern regions of Goguryeo were almost all in the hands of the Tang Dynasty. Especially after Pyongyang fell, even the city of Beisha, which had been resisting, surrendered to Zhang Liang's army, and many were captured by the Silla people in the east. At the same time, Li Shimin was also clearing the remaining troops in the east. The only one who was still controlled by the Tang army was the north.

Most of the north are mountainous areas, and the natural environment is relatively harsh. For example, although the near Marudu City is the birthplace of Goguryeo, most of the Goguryeo people moved to Pyongyang later. Therefore, compared to the southern part of Pyongyang, the north should be much more desolate. You can rarely see crowds living together along the way. At most, some tribes that make a living by hunting appear in the mountains and forests.

Qin Qiong led an army of 30,000 to advance towards Maruto City. Although he encountered many difficulties on the road, it was mainly because the road was too difficult to walk. Especially now it is autumn. Not only is the weather starting to get cold, but it also rains occasionally. Although the rain is not heavy, it is so cold that it feels like it will be numb all over when it falls on people.

However, although the road is difficult to walk, at least we did not encounter any decent enemies. There were several small cities on the road. However, the Goguryeo people in the city surrendered without any resistance when they saw Qin Qiong's army. And they also found out from these small cities that Quangasuwen did pass by here some time ago, and now they should have arrived in Marudu City.

After getting the exact news from Quangai Suwen, Qin Qiong discussed it with Li Xiu and Cheng Yaojin, and then accelerated the marching again. In late July, they finally came to the Yalu River again. It is worth mentioning that Marudu City is on the west bank of the Yalu River. When Li Xiu was in his previous life, Marudu City belonged to Ji'an City, Jilin Province, across the river from North Korea.

However, compared to the mouth of Bogoukou, Marutou City belongs to the upper reaches of the Yalu River. The river is not very wide, and the terrain opposite is very wide. Looking across the river, you can see a medium-sized city at a glance. However, this city is not Marutou City, but another domestic city in Goguryeo, which is also the earliest capital of Goguryeo.

In the northwest of the domestic city, there is a continuous mountain range, one of which is Marutou Mountain, and Marutou City is built on this mountain. The entire city almost occupys the entire mountain. The city wall is also built according to the mountain. The terrain is very dangerous. Although it was destroyed twice by war, it was later restored by Goguryeo, and it is still a natural danger now.

The crossing of the river was very smooth this time. As soon as the river surface was not wide and the terrain was not dangerous. If Quangai Suwen wanted to intercept it, he would have to dispatch a large number of troops. Now he only had more than 30,000 defeated soldiers and did not dare to fight the Tang army on a large scale again. Now they are all huddled in the domestic city and Maruto city.

After crossing the Yalu River, Qin Qiong immediately commanded the army to the south of the domestic city to set up camp. The Goguryeo people on the top of the city were also very nervous. After the camp was arranged, Qin Qiong, Cheng Yaojin and Li Xiu went out of the camp together and climbed a nearby hill to observe the terrain around the domestic city.

The domestic city is surrounded by mountains, but a large plain appears among the mountains. This is also the origin of the Goguryeo people. The plains are full of cultivated fertile fields, but now they have been harvested. It is estimated that the domestic city and Marudu also store considerable food. In this way, siege alone will definitely not work.

Li Xiu held up his telescope and looked at the domestic city carefully. Although the city did not look very big, and even the walls were not very high, at least they could not be compared with Pyongyang City, there was a place that made Li Xiu frown because the shape of the domestic city was very strange. The shape of the city was originally not large, and it suddenly extended some from behind, connecting the domestic city with the mountains behind. In this way, the entire city was snuggled with the mountains.

It was not surprising that the city was built on the mountain, but the one that was close to the domestic city was Marutou Mountain, and the mountain was very steep. The road to the mountain was in the domestic city. In other words, if you want to attack Marutou, you must conquer the domestic city. Even if you conquer the domestic city, the army in the city could retreat to Marutou City. In addition, the mountain road was very dangerous. Not to mention attacking Marutou City, it would not be easy to even go up the mountain.

"Marudu City is so steep. Wuqiu Jian was the natural danger he had broken through?" Cheng Yaojin looked at Marudu City in the distance for a long time, but finally took a long breath and said, although he had heard that Marudu City was easy to defend but difficult to attack, but when he saw it with his own eyes, he found that this city was even harder than he thought.

"I had collected some news about Marutou on the way to come. It is said that because Marutou has been breached many times, the Goguryeo people later destroyed some of the uphill roads in Marutou Mountain. This mountain was already dangerous and there were not many roads to go up the mountain. Now there is only one road left in the domestic city, and it is very dangerous. What's worse is that Marutou Mountain has water and food, which is enough for them to support until the arrival of winter." Li Xiu explained in a low voice at this time.

"This is indeed bad news, but it is not completely impossible to capture Marudu City. I remember history books once recorded that when King Murong Huangguang of Yan attacked Marudu City more than two hundred years ago, there was no progress at the beginning. Later, he set fire to the mountain in anger. The forests on Marudu Mountain were dense, and the houses in Marudu City were burned. In the end, Goguryeo was killed or injured, and Marudu City was also destroyed by the fire." At this time, Qin Qiong also spoke, although setting fire to the mountain hurt Tianhe, there was no tolerance for any kindness on the battlefield, let alone this place was not the Tang Dynasty, so he didn't have to worry about hurting the people by chance.

"Shubao, take a closer look. The forests near Marudu City seem to have been cut down. I'm afraid you can't burn the other party's city if you want to set fire!" However, just as Qin Qiong finished speaking, Cheng Yaojin pointed to Marudu City Road on the top of the mountain.

Hearing Cheng Yaojin's words, Li Xiu and Qin Qiong hurriedly raised their telescopes to observe carefully. Finally, they found that all the trees near Marudu City had been cut down, and a barrier belt that was about a width was vacant. However, because the mountains were dense, if you didn't look carefully, you wouldn't be able to find it for a while. It seemed that the Goguryeo people had learned their lessons. Even if the Tang army set fire, they would not be able to burn Marudu City.

"This is bad. If the fire attack is ineffective, then we can only start attacking from the domestic city honestly." When Qin Qiong saw the isolation belt outside the Marunto City, he couldn't help but frown and said.

"It is not difficult to fight the domestic city. Although Maruto City can send reinforcements, with the defense of the domestic city, it should be easy to blow up the city gate with gunpowder. After controlling the domestic city, it is not too late to consider attacking Maruto City." Cheng Yaojin said again at this time, no matter what method is used, he will still capture the domestic city, otherwise he will not even be able to find the way up the mountain.

Hearing Cheng Yaojin's words, Qin Qiong nodded, but at this time he found that Li Xiu had been thinking and silent, which made him ask curiously: "Mr. Concubine, I wonder what you can do?"

"The solution is not yet discussed, but I have a vague idea. And as General Cheng said, it is not too late to defeat the domestic city first and then make plans." Li Xiu raised his head and smiled. Although Marudu City had made many defense preparations, there may not be no way to overcome it through some technical means. It depends on how they did it.

Seeing that Li Xiu did not say in detail, Qin Qiong and Cheng Yaojin did not ask again. At that moment, the three of them carefully observed the situation in the domestic city. Someone raised a hot air balloon in the camp and began to observe the domestic city under the high custody. Soon, the situation in the city was reported, and Qin Qiong and Cheng Yaojin also began to study the plan to attack the city.

At the same time, on the top of the city of the domestic city, Quan Gai Suwen and his son Quan Nanjian were also looking at the Tang army's camp. Although it had only been more than a month since the last escape from Pyongyang, Quan Gai Suwen suddenly got much older. There were a few wrinkles on his originally determined face, and there were a lot of white hair on his temples. Even if he escaped to the domestic city, he did not dare to relax for a moment. He had been setting up defense matters during this period.

"Father, the number of the Tang army seems to be no more than 30,000. We still have a little advantage in terms of military strength. With the help of the city defense, there should be no problem to defend here." Quan Nanjian looked at the Tang army's barracks for a while, and then said to Quan Gai Suwen with some excitement. They had previously guessed that the Tang army occupied Pyongyang City and would definitely divide their troops to guard it. Now it seems that this is true.

"Have you not experienced the combat effectiveness of the Tang army yet? Even if the other party has only 10,000 people, you must not underestimate it. During this period, you should hurry up and transfer the materials from the domestic city to Marudu City, and try not to leave anything behind!" Quan Gai Suwen scolded with a serious expression.

"Father, do you really want to abandon the domestic city?" Quan Nanjian couldn't help but ask unwillingly when he heard his father's words. After coming to the domestic city, Quan Gai Suwen made a decision to abandon the domestic city and concentrate all his troops to guard the Marun Capital, which made Quan Nanjian very puzzled. After all, although the domestic city is not as good as Pyongyang in defense, it can also consume part of the Tang army's troops.

"There is almost no danger to defend the domestic city, and it can't be defended for long by relying on the city wall. I also forgot that the Tang army had the weapon of gunpowder, and no kind of city wall could stop them. Therefore, dividing troops to guard the place would only consume our strength. It would be better to concentrate all our troops in Marudu City, so that our chances of victory can be greater!" Quan Gai Suwen said without hesitation.

In fact, there is another reason why Izumi Suwen didn't say, that is, he led more than 30,000 people from Pyongyang to escape here. It was already panic and the soldiers were not willing to fight. If they experienced another defeat, the hearts of the people in the army would be completely dispersed, so it would be better to abandon the domestic city directly and take a bet on the natural danger of Marudu City!
