The central army commanded by Li Ji did not directly capture Xincheng, but quickly captured three small cities around Xincheng and stripped the new city of defense system. Now Li Ji's army is already in a siege of Xincheng. At the same time, Li Ji sent a flight force to inquire about the enemy's deployment. Thirty pilots relied on the mountains around Xincheng to glide over the new city, and regarded the deployment of the new city's military power completely.

This doesn't need to be carefully looked at, it can be judged by the number of camps.

The cities in Goguryeo are all built against the mountains, and the flying troops like this environment. If you want to build them on the plain, where will I take off?

In just one day, Li Ji knew the deployment of the new city well, which was much easier to fight.

As the saying goes, know yourself and your enemy, you will never be defeated in a hundred battles.

Li Ji immediately formulated an offensive plan for the deployment of Xincheng.

After three days of fierce battle, Li Ji's army won the new city without any bloodshed, and then took down seven surrounding cities in one go.

Goguryeo was shocked by the whole country. They did not expect that the Tang army would break through the Liaoshui defense so quickly, which was sharper than ever before.

Now, only Anshicheng has not been broken in the entire Liaoshui waters, because Xue Rengui, Liu Renyuan and Gao Kan have just headed north and are attacking the defense line of Anshicheng. After learning that Li Ji has captured the new city, his morale has been greatly boosted, and in this way, Anshicheng has become an isolated city.

Before they could approach the city, Yuan Gai Suwen decisively ordered the entire Liaoshui area to completely give up the entire Liaoshui area, and appointed Yang Wanchun as the commander of the former army, and tried his best to delay the Tang army's attack and retreat. Then he ordered all the soldiers and civilians from the Liaoshui to Yalu River to retreat to the Yalu River, and began to implement the scorched earth strategy. Take away as much as possible, and burn them if they can't be taken away, so as not to leave any supplies for the Tang army.

As soon as Yang Wanchun's army retreated, Xue Rengui and Gao Kan easily occupied the Anshi City that had never been captured.

However, Yuan Gai Suwen doesn't take the Tang army seriously. If you always use this trick, if you play too much, you will always find flaws.

This time, the Tang army didn't care about this scorched earth strategy at all. Do you like to burn it or not? Anyway, we have food, so who cares about your food?

Because Han Yi had already planned it, the logistics army advanced along the way, following the army along the way. Anyway, Goguryeo implemented the scorched earth strategy and no one left it for him. Han Yi felt that it was much easier. Moreover, the logistics army was in Shicheng, and Jilicheng had a lot of labor to supplement it. The road here is difficult for you to walk, so I went directly to the sea, and even the donkeys were transported directly on the boat to help the donkeys save their energy.

Because Goguryeo had a scorched earth policy, it would not be stationed on the coast at all, so it gave up completely, so the logistics army was smooth sailing. Moreover, although the Tang army was divided into three groups, the southern route was the fastest, because they were closest to the logistics army and were all marching lightly. After reaching the assembly point, they immediately prepared the road. As soon as the logistics army arrived, they immediately asked the prisoners to take a donkey cart and the cart went north to provide supplies to the central army. On the north route, Qibi Heli and others would go north to attack Goguryeo's allies, Baishan Muhe and other tribes.

Then the supply route is very short, and Han Yi and the others chose in advance that the nearby roads were well-connected. Goguryeo's scorched earth strategy was able to burn the house, but he could not destroy the road. This was not a railway or a road. In this situation, where could the road be damaged?

Moreover, the emergence of assembly technology has greatly improved the Tang army's advance speed.

When marching, everyone can just carry a part on their body, which can be kept in their pockets at least. When they arrive at the station, they can just take out the parts and assemble them. Even the siege trucks are dismantled and transported. Because the Ministry of Works has already popularized production of assembly lines, no matter what equipment is designed, it can be dismantled more finely, and then dismantled more finely.

The baggage was broken into pieces, so the marching speed would naturally be much faster, which was very beneficial to the Tang army, and it could even be said to directly affect the victory or defeat, because the Tang army had to try to eliminate Goguryeo before the winter came.

At the same time, Su Dingfang's troops on the Eastern Front were also advancing westward with 50,000 elite troops commanded by Silla King. Goguryeo did not implement any scorched earth strategy on the Eastern Front. Not only that, Yoon Gassuwen also transferred a lot of troops to defend. It can be seen that even at this point, Yoon Gassuwen was still very calm. He knew that the main forces of the Tang army were in front, and I would not fight head-on with the main forces of the Tang army. I tried my best to drag it out and waste the Tang army in the most favorable terrain.

First destroy the Tang army behind.

He knew that he had to fight back, otherwise, it would be too difficult to fight on both sides.

Unfortunately, Su Dingfang was not an ordinary person, and he was also a fierce man who was ignored in the Tang army. His military talent was not inferior to Li Ji. He was always suppressed, so he was often ignored. Although he was only fighting for Su Dingfang's partial army, Su Dingfang only wanted an opportunity. What's even more terrible is that Su Dingfang was still warming up in Baekje in front of him. He was used to the land and water of this place, and captured the entire Baekje royal family. His hands were hot at this time. He was really energetic and used his troops like a god. Goguryeo, which was stronger than Baekje, and his troops were not superior, he still won consecutive battles and maintained an invincible life. With the assistance of Liu Rengui and Liu Boying, he fought so well.

This can't stop it!

Forced Yuan Gai Suwen to send his eldest son Yuan boy over and must block Su Dingfang.

Large military camp tent.

At this time, Su Dingfang and Liu Boying formulated the next combat plan.

"If we continue to fight like this, we will soon arrive at Pyongyang City." Liu Boying said very excitedly.

They marched from the Eastern Front, which was very close to Pyongyang, and the distance was more than twice as short as the main force in front. Originally, they were just trying to restrain Goguryeo and cooperate with the main force in the battle, but they didn't expect that they would arrive at Pyongyang City first.

Su Dingfang did frown and said, "But our troops are really limited. It is probably not that easy to siege Pyongyang City. I don't know where Sikong and the others are fighting?"

Liu Boying thought to himself, if he had to wait for the main army, wouldn’t this credit be counted on Li Ji again? He said, “Are there 50,000 elite Silla Kings there? Goguryeo’s main force must be on the front line. If we can reach Pyongyang City, they will be in a dilemma. This is our opportunity. We should quickly ask Deputy Envoy Yang to send some siege equipment to attack Pyongyang City.”

He didn't expect the fight to go so smoothly. Since the opportunity has come, he has to seize it.

Su Dingfang was very moved and nodded slightly. He also wanted to prove himself, saying, "I don't know what the Silla King is doing. It seems that we have to ask someone to inform them, join forces with our army, and prepare to besiege Pyongyang City."

As soon as he finished speaking, he heard a rushing shout.

"Report!"

A notice officer almost rolled and crawled into the tent, "Reported to the Grand Chief, the enemy commander Yuan, the main force of Silla on the northern line, and cut off the rear route of Silla. Now the Silla army is trapped in the valley in the north, and the Silla King asks our army to support them."

Liu Boying said excitedly: "How is this possible? The main forces of the enemy are resisting our army."

"According to the information inquired, the boy Yuan only brought 10,000 soldiers over."

"The King of Silla is really a waste."

Liu Boying was so angry that he cursed, beating 50,000 yuan and being surrounded by people. How could he figure it out, and he said to Su Dingfang again: "Just those wastes, we're so dead, so let's not save him."

Su Dingfang was so depressed that if he could join the Silla army at this time, the force would be very considerable and he would have the opportunity to invade Pyongyang City. He did not expect that Silla would lose its chain at this time, but he did not reveal it and said, "We must save them. Without Silla's support, it would be difficult for us to besiege Pyongyang City."

Liu Boying stomped his feet hard and kept muttering.

As the saying goes, this tiger father has no dog son, and the Yuan boy is not a second-generation. He has been with Yuan Gai Suwen since he was a child and has experienced many battles. After he came to the Eastern Front to take over, he saw that the Tang army was unstoppable, and he knew that he might not be able to defeat Su Dingfang. Since that is the case, don’t compete with Su Dingfang. The earth is round, and we can also increase our morale.

Goguryeo has been suppressed and beaten by Tang Jun, and it has been hit with psychological shadows, but Silla has been suppressed and beaten by Goguryeo. The relationship between the three is very interesting.

So the boy from Ancestor changed his strategy. We didn't fight against the Tang army head-on, and we went to fight the Silla army. He knew very well that Su Dingfang had limited troops and without Silla's support, Su Dingfang could not cause any big waves. He could hit me with his fist, but you didn't have enough strength to kill me, so he personally commanded 10,000 elite troops to attack the Silla army, and the main force was still here to resist the Tang army.

The soldiers of Goguryeo were so angry that they were beaten by Su Dingfang, but they could not beat Su Dingfang. After several counterattacks, they not only failed, but were beaten by Su Dingfang. Then they could only spread all the resentment they received on the Tang army on the Silla people, because they often teased Silla and had an absolute advantage on the psychological level. They all bite their back teeth and beat the Silla army. This is actually human nature. If you bully me and I can't beat you, then I will bully enemies who are weaker than me and find a balance.

Seeing that Pyongyang was right in front of him, Su Dingfang had to temporarily change the route and turn the spearhead to save Silla King. The Silla Army was slow to advance and were still behind. However, Su Dingfang was in battle for a long time, and there were enemies in front of him, so he didn't dare to take it lightly, so he asked Liu Boying and Liu Rengui to command the rear army to rescue Silla King first. He himself led the main force to cover them, and while covering them, he also retreated north. He had few troops and divided his troops out. He did not dare to stay here, for fear of being defeated by the enemy one by one.

The man Yuan really kept his hand. He ordered a general to monitor the Tang army at this moment. If the Tang army rushed to rescue Goguryeo or divide the troops, then ambush the Tang army halfway. The general saw that the Tang army retreated in an orderly manner and had all the defenses. He had no chance to start. In addition, Su Dingfang's military flag was erected in front of him. The soldiers here felt timid when they saw the Su Dingfang's military flag. So they thought about it and let it go. This life is precious and I really can't be violated.

The boys in Nayuan could stop Su Dingfang from moving forward, but no one in the world could stop Wu Meiniang from moving forward.

Yuzhou.

"Grandpa! Grandpa!"

Changsun Yan came to Changsun Wuji's door, shouted a few times, but there was no answer. He faintly heard the sound of crying from inside. An unknown premonition surged into his heart. He pushed open the door suddenly, and the scene in front of him made him stunned. He saw Changsun Wuji hanging on the rope on the beam, and the old housekeeper beside him was kneeling below, crying in tears.

"grandfather--!"
