After crossing the Sashui River, the Tang army continued to advance eastward.

In the afternoon of that day, 20,000 light cavalry had quietly dismounted ten miles outside Pyongyang City, and then fled into the mountains and forests. The entire army quietly rested in the mountains and forests and waited for darkness.

With the help of the corpse, Li Su climbed up a big tree and looked forward with his eyes narrowed. He saw a black city wall looming in the distance. Only one outline could be seen in the city wall, but he could vaguely feel its majestic martial arts.

Outside the city wall is a vast plain, suitable for cavalry to rush and charge. It is too far away. Li Su can't see anything else except these.

After turning over the tree neatly, Fang Laowu presented wet wipes, Li Su carefully wiped his hands, and then he let out a breath.

"After all, it is the capital city. The walls are built high and long. If you attack according to ordinary methods, it will cost at least 50,000 casualties to capture this city."

Fang Laowu sneered: "It's far worse than our Chang'an City. If anyone dares to attack Chang'an City, it's not enough to throw away a million people."

Li Su smiled and said, "Where is my uncle?"

"The general rests in the forest. Is the prince going to see him?"

Li Su nodded, and Fang Laowu led him to the depths of the forest.

The mountains and forests are densely covered with trees. The deeper they go, the dimmer the light becomes. When it reaches the depths of the forest, it is almost pitch black.

Li Su took a long time to find Li Ji. Li Ji was leaning against a tree and closed his eyes to rest. A hundred personal guards next to him formed a circle to guard the surroundings.

Seeing Li Suxing coming, the guards saluted one after another and then made way.

Li Ji woke up when he heard the footsteps. When he saw Li Su coming, he nodded to him lightly.

"Did you see Pyongyang City? What do you think?" Li Ji asked.

"If you attack with a strong force, it may not be easy to take. If only our troops are the only one, the defenders can easily defend the city even if they only have two thousand. If you take Pyongyang, you should only launch a surprise attack. You must not attack with a strong force, otherwise you will not be able to imagine casualties." Li Su said with a smile.

Li Ji nodded: "If you don't want to win in everything, you will first think about defeat. At midnight tonight, if the king Gao Zang cannot open the city gate as promised, we will remain calm and wait until tomorrow to use the method of taking Qingzhou City, so that Xue Rengui will lead 500 people to disguise themselves as Goryeo people and scramble into the city, and force the city to open the city tomorrow night."

Li Su thought for a while and said, "My uncle, I am not my race, and my heart will be different. I think we should not put our hope on Gao Zang. Although they are eager to seize power, they may not trust us. Especially since our Tang Dynasty had just fought with Goguryeo, Gao Zang was the king of the country. Isn't it any warning to us? It's impossible to say that. If he sets a trap in the city, our 20,000 soldiers will die without a place to bury."

Li Ji narrowed his eyes: "Where is the true opinion of Zi Zheng?"

Li Su pondered for a moment and said, "I think we should send Xue Rengui to lead 500 people into Pyongyang City now. After midnight tonight, it would be best if Gao Zang opened the city gate as promised. If he failed to open the city, he would let Xue Rengui seize the city. It would be more at ease to leave the major matters of life and death to his own people."

Li Ji nodded and said, "Yes, this idea is reasonable. I'm sure. I'm here. I'll tell you that Xue Rengui is here."

Soon, Xue Rengui appeared in front of the two of them in armor.

After Li Ji gave the military order, Xue Rengui bowed and accepted the order. Before leaving, he smiled at Li Su.

After nightfall, the mountains and forests became quieter.

As soon as he finished speaking, he saw a dazzling flame suddenly rise under the Xicheng Gate of Pyongyang in the distance. The fire was very strong, almost illuminating half of the city wall.

Gao Lingzhen was also excited: "Look, my father's letter has been raised!"

Li Su said coldly: "That fire was not released by your father, but Xue Rengui. This is what I said about the 'backhand'."

Li Ji was so excited that he slapped his thigh: "Xue Rengui is so good! The city gate has been successful. I will send the order. The whole army will get on the horse and head towards the city gate!"

Twenty thousand people all boarded their horses in the dark night and began to rush towards the city gate.

Gao Lingzhen stayed there, her face still pale as paper.

The army had already started, but Li Su and Bai Mingmen rode on the horse calmly. Following the team, Gao Lingzhen felt as if she had lost her soul, and let someone help her onto the horse and slowly headed towards the city gate.

Twenty thousand Tang troops rode their horses and were only three miles away from the city gate. The Tang troops suddenly lit a torch, one, two, hundreds, and thousands...

The rapid sound of gongs and drums came from the city tower. Under the city gate, Xue Rengui could vaguely see the leaders of 500 disguised soldiers fighting to the enemy guarding the gate to the death. The battle was extremely fierce. The enemy rushed towards the city gate desperately, trying to regain control of the city gate, one after another. As the sound of horse hooves of the Tang army outside the city became closer and closer, the counterattack of the enemy guarding the gate became more and more crazy.

Xue Rengui was covered in blood and held a long halberd in front of the city gate. The soldiers behind him were more or less injured, but they refused to give in. They squeezed into the narrow corridor with the enemy, fighting with each other with one shot and one halberd.

It was exactly the same as the capture of Qingzhou City. The Tang army's cavalry was getting closer and closer, and the defenders became more and more desperate. When the first group of cavalry rushed into the city gate corridor, the enemy crowd let out a sad and desperate wail. Then some people threw down their weapons and turned around and ran away, while others tried their best to become more and more intense.

The situation is hopeless and irreversible. Hundreds of years have passed, and the Central Plains dynasty has tried to conquer this rebellious enemy capital countless times, but in the end they have failed and their ambitions have not been fulfilled. Until today, the first batch of Tang troops rode horses and spears and rushed into the city with force.

The iron cavalry entered the city, and the horse speed remained slow. Soon, the second and third groups rushed into the city one after another. All the enemy troops who dared to resist were killed mercilessly on the spot. Not long after, fires lit up everywhere in the city. Countless people in the streets and alleys were panicked and fled everywhere. Countless defenders were furious and fought hard. The whole city was sobbing and crying in the fire.

Xue Rengui was already riding on the horse at this time, holding a shiny long halberd in his hand. The tip of the halberd reflected the fire, reflecting a trembling light.

"Capt the palace immediately! The rest control the city gates and eliminate the remaining enemies in the city!" Xue Rengui shouted in a daze.

The iron cavalry of the Tang army that kept pouring into the city dispersed according to the order. Finally, when General Li Ji rode his horse into the city, the Tang army had almost controlled the entire city.

Because Quangai Suwen allocated all the defenders in the capital to the greatest extent, this capital could almost be called an empty city. The huge city had only more than 2,000 defenders, some officials and some guards in powerful families. The Tang army entered the city and wiped out the enemy even if they felt it was easier than attacking Qingzhou City, so they quickly controlled the city.

Xue Rengui was covered in blood and rode his horse to Li Ji, giggling at him.

Li Ji glanced up and down at him, showed an admiring look, and smiled and said, "Is there any injury? How about the casualties of the soldiers below?"

"Report to the general, the last general is not injured. The five hundred brothers below are about 200 casualties, and the specific number is still not yet settled."

Li Ji nodded and looked up at the city with fires everywhere, as well as the buildings and people with exotic flavors everywhere. Li Ji suddenly felt aroused in his heart and laughed to the sky.

"I have obtained it in Pyongyang, the capital of Goguryeo!"
