Sofusun was the chief of the Sofu tribe of Goguryeo. His ancestors were stationed in Bozhuo City for generations. Sofusunsu led 30,000 troops, all of which were the elite Goguryeo who were stationed in Bozhuo City, and it was not comparable to those of the Mushi tribe's extra-headed soldiers.

After receiving the order from Yoon Gaisuwen, Sofu Sun immediately led his troops out of the city and rushed towards Pyongyang City. He followed Yoon Gaisuwen's order to attack Xue Rengui with Yoon Gaisuwen inside and outside.

Xue Rengui raided Pyongyang City to make an isolated army, with great benefits and great risks. When Xue Rengui's army entered the hinterland of Goguryeo, Xue Rengui ordered scouts to seize the movements of the troops around Pyongyang City as much as possible. Therefore, when Sufusun led his army out of Bozhuo City, Xue Rengui got the news.

Ten miles outside Pyongyang City, the Tang army camp.

"Reporting to the Great Protector, news came from the north that Sun, the lord of Bozhuo City, led 30,000 troops to come south, and he was afraid that he would arrive tomorrow as soon as possible." The scout stood in the commander's tent and reported to Xue Rengui.

Xue Rengui waved his hand and signaled the scout to push it down. Then he said to the deputy general Qie Heli sitting beside him: "The 30,000 army, this Bozhuo City is probably coming out in full swing."

"Bozhuo City is only behind Daxing City, and is reserved for Daxing City. Now Daxing City is under the command of the general's army. Goguryeo actually transferred the army of Bozhuo City. It seems that the guardians of the capital are here, and Yuan Gaisuwen is anxious." Qi Bi Heli said to Xue Rengui.

Bozhuo City and Daxing City are mutually supportive. Although the location is not as dangerous as Daxing City, it is also a major place. Now that Bozhuo City has all its troops, it naturally makes people want to take a lot of money.

Xue Rengui said: "We just arrived at the city, and Yuan Gai Suwen transferred these 30,000 troops. I think it is because he has a lot of hope for them. If we can defeat them, the enemy in Pyongyang will be brave and the city will be captured."

He Li heard this and asked, "The Protector wants to take the initiative to send troops to defeat the reinforcements in Bozhuo City?"

Xue Rengui said: "Yes, Sofusun led his army from Bozhuo City to help Pyongyang City and attack our army inside and outside with the defenders in Pyongyang City. Once Sofusun led his army outside Pyongyang City, our army would be trapped in a dilemma. So in order to avoid this, we must take the initiative to attack and defeat Sofusun first."

Yuan Gaisuwen wanted to rely on the city to defend, and then attacked Sofusun, who came to help, and worked together to destroy Xue Rengui's 30,000 elite troops. If Xue Rengui wanted to avoid this situation, it was nothing more than two ways. He either broke Pyongyang City before Sofusun's army arrived in Pyongyang City, or destroyed Sofusun first.

It is easy to defend and difficult to attack. It is obviously not easy to break Pyongyang quickly, so Xue Rengui chose a relatively easy path, which is to destroy the Sofu Sun tribe who came to reinforce.

But Xue Rengui's arrangement was not without loopholes. Qi Bi Heli said to Xue Rengui: "Although what the Grand Protector said can solve the current difficulties, when our army went to wipe out the Sun tribe of Sufu, if we sent troops in Pyongyang City and attacked our rear army, wouldn't our army be attacked from both sides and might even be surrounded and annihilated?"

Xue Rengui shook his head and smiled and said, "You don't have to worry about this. Can't I keep 20,000 elite troops for you? Can't you stop the thief army in Pyongyang City?"

Qie Heli is also a general in the army and is good at using troops. The force in Pyongyang City is only 20,000. If Qie Heli is given 20,000 troops, even if he can't take Pyongyang, he will definitely be able to surround Pyongyang into an iron wall, and even if he can't leave the city, he will not be able to leave the city if he can't.

However, Xue Rengui's total was only 30,000. If this were the case, there would be no more than 10,000 people who followed Xue Rengui to defeat the enemy. With 10,000 Tang troops, it would not be easy to defeat the 30,000 elite troops of Goguryeo.

Qi Bi Heli hurriedly asked, "The Protector only wants to lead 10,000 troops to destroy the grandson of his husband himself?"

Xue Rengui replied: "To destroy my husband's Sun tribe, I only need ten thousand light horses."

Qibing Heli said worriedly: "From Pyongyang to Bozhuo City, there are mostly roads along the way, and it is probably difficult to use ambush, and there is no advantage of terrain. Will the Protectorate be a little rash to block the enemy with only 10,000 troops?"

Xue Rengui smiled and said, "It is precisely because they are all plain roads that I dare to use ten thousand light cavalry to block the enemy. I have been in Liaodong for four years and are somewhat familiar with the deployment of troops in Goguryeo. The young horses of the Sofu Sun tribe in Bozhuo City are mostly infantry under my command. I can use the plain terrain to defeat the enemy head-on, but you must be careful to keep an eye on the movements of Pyongyang City."

Qibing Heli responded: "Don't worry, the Protector will form a formation outside the city of Pyongyang. If the Goguryeo dares to leave the city, they will definitely be allowed to leave without returning."

—————————————————

Li Ke's arrangement of Goguryeo was leaning against each other, and used strangeness to assist the righteousness. This righteousness was Li Ji and Su Dingfang's army, while strangeness was Xue Rengui's 30,000 light cavalry that directly attacked Huanglong.

The two armies of the north and south routes divided the Goguryeo Fortress, forcing Goguryeo to divide the heavy troops to defend, weakening the defense of Pyongyang City and giving Xue Rengui the opportunity to win the enemy's confidant.

Similarly, Xue Rengui's besieging the city in Pyongyang also intimidated the soldiers on the North and South Front of Goguryeo, and also relieved certain pressure on Li Ji and Su Dingfang's army.

Su Dingfang's army headed north from Silla, Baekje Aisle, first broke Dongbi City, then took the ancient city of Hai, and then occupied Minei City. In just ten days, he headed north all the way to Seoul.

Seoul is the capital of Goguryeo, an important town in the south. It leans against the tributary of the Yushui River to the north and then moves north. After passing Donghu City, it is Pyongyang, the capital of Goguryeo.

Since attacking Su Dingfang and Kim Yu-sun and his army, whether it is to attack Si-san or surrender Xiongjin-sun, Kim Yu-sun has never seen Su Dingfang take a war seriously. However, since attacking Su Dingfang to Goguryeo, he has seen Su Dingfang's ability to use troops and the imperial guards that the Tang Empire relied on to dominate the world.

In just ten days, the Tang army went north to Goguryeo, and won eight battles along the way, and they all fought quickly. In the eyes of Kim Yuxin, the southern border troops in Goguryeo, were as hard as paper in Su Dingfang's hands. The Tang army entered Goguryeo's hinterland at an incredible speed.

Outside Seoul, the Tang army tent.

"The last general met with the general. I wonder what the general is going to do when he is in the camp?" Kim Yu-shin was sent to Su Dingfang and said to Su Dingfang.

Su Dingfang asked: "What progress has the Silla Army made invasion of the west gate of Seoul today?"

The Tang Dynasty and Silla coalition forces attacked Seoul, and the Tang army attacked the north and south gates, while the Silla army attacked the west gate. Kim Yuxin heard Su Dingfang's question and replied: "Seoul is the capital of Goguryeo, the largest city in the south. It has many soldiers and abundant food, and it is difficult to break. The last general will attack the city for one day today, but there is no major progress."

Upon hearing this, Su Dingfang nodded and said, "It is indeed not easy to break Seoul, but this matter cannot be delayed anymore. I just got the news that Xue Dudu from Liaodong has already taken small path troops to Pyongyang City. Xue Dudu is advancing here to go deep alone. Although he has made great achievements, he has also been placed in a dangerous place. Therefore, we must open up the southern road of Goguryeo as soon as possible, relieve Xue Dudu and assist in the battle in Pyongyang City."

Kim Yu-shin was surprised to hear that Xue In-gui had already surrounded Pyongyang. In his eyes, Goguryeo was also a powerful country, but he did not expect that the war in the north would progress so quickly that Xue In-gui had arrived in Pyongyang.

When Su Dingfang was in front of him, Kim Yu-shin did not dare to refuse, so he could only say: "The last general will receive the order, and the last of tomorrow will be the final contribution of Seoul, and the place will be destroyed as soon as possible."
