On the plain on the right bank of the Central Plains of the Yalu River.

A majestic city stands, and this is the domestic city of Goguryeo that was once the capital of the country for 425 years. Goguryeo was founded 700 years ago, the national capital has been relocated several times, and today's national capital Pyongyang has only been the national capital for 200 years.

Although compared to Pyongyang, the domestic city was far inferior to the capital of the middle Goguryeo period in terms of scale and wealth, but after all, it was the national capital for 425 years.

The domestic city leans on Yushan Mountain, faces the Yalu River in front, and stands on the bank of the Tonggou River, when it enters the river.

Gao Jianwu suddenly arrived at the city with an army of 80,000.

Looking at the city in front of him, Gao Jianwu was still frowning.

"Yuan Taizuo is in the city of China now, do you think he knows the news of Pyongyang?"

"I rushed back from Pyongyang on the starry night, and when I came, I also ordered the news to be blocked, so that it should not spread northward, and Yuan Taizuo should not know yet." Ulji Mundeok is still a light cavalry outfit, and except for a few people in the army, most people don't know that this marshal who went to Pyongyang is actually in this army.

And the vast majority of Gao Jianwu's 80,000 troops did not understand why they suddenly retreated from the city of Daxing, and instead of returning to Pyongyang, they ran to the domestic city.

"There are about 10,000 soldiers and horses in Pyongyang City now, and these people are all the eastern tribal army of Yuan Taizuo, if we really want to fight, I am afraid that it will not be easy for us to take the city." Gao Jian Wudao.

Eulji Wende looked at the city, but he didn't think there was a need for war, and he was very sure that he believed that Yuan Taejo did not know about the upheaval in Pyongyang.

"After entering the city in a while, first summon Yuan Taizuo to the palace, and we will force him to support you to succeed to the throne."

"What if he refuses?"

"Kill him, and then declare to the public that he fell ill and died."

The soldiers and horses slowly came to the domestic city.

In fact, there are three domestic cities, one is the earliest established domestic city, which is built on the mountain behind the plain, it is a typical stone fortress mountain city, the circumference is only three miles, and it is actually more like a fortress to say that the city is actually more like a fortress.

That castle was the earliest royal city of Goguryeo, and later when Goguryeo's power expanded, a plain city was established on the plain under the mountain, and this plain city was also a stone city, with a circumference of about five miles and roughly square. Later, at the foot of the mountain, a larger domestic city was built according to the original mountain.

The domestic city that blocked Luo Cheng's southward movement last time was the largest domestic city, at the foot of the mountain on the edge of the plain, directly enveloping a valley, and the city was surrounded by more than ten miles.

However, now the domestic city they came to is the domestic city of the plain, which is actually very close to the domestic mountain city and the domestic castle, and the three cities are only twenty or thirty miles apart, so they can rely on each other.

Yuan Taizuo was sitting in the city of the domestic plain at this time, and he was busy sending troops to pursue and hunt down the defeated and fleeing Goguryeo army during this time, and it was still the largest Sui army prisoner concentration camp in Goguryeo, where more than 150,000 Sui prisoners were held.

"Why did General Gao suddenly lead his army here?"

Yuan Taizuo led his troops out of the city to see Gao Jianwu, and he was a little surprised.

"I have just broken through Daxing City, recovered the city, killed many Sui troops, and captured many prisoners. Now I will come to the country on the orders of the king, transfer the prisoners to Mo Lizhi, and then I will lead my troops to the front line of the Liao River to support the soldiers of Zhucheng there. Seeing that autumn is about to begin, it is time for us to launch a counterattack, and then it is time to drive the Sui army across the Liao River, drive out of Liaoxi, and take advantage of the victory to take Liaoxi as well. ”

When Yuan Taizuo heard this reply, he didn't feel anything wrong.

In fact, these were indeed discussed in several previous meetings of the Goguryeo court. If the Sui Dynasty naval division and the Ninth Army were defeated under the city of Pyongyang, the more than 100,000 troops gathered on the front line of Pyongyang would have to fight back to Liaodong.

"I heard that a Sui army went to Pyongyang?"

"Well, it's part of the Fifth Army of the Left, and this gang of thieves has the audacity to flee south. But don't worry, Marshal Yizhi has already chased after tens of thousands of horses, and none of these guys want to run. ”

After chatting a few words, Gao Jianwu asked to enter the city to rest.

Yuan Taizuo didn't refuse, although he didn't have a good relationship with the royal family, but under the balance of many years, the game between the two sides was actually more in the dark, rather than this kind of open knife and gun.

Besides, now that the enemy is present, both sides are at the same gunpoint, and I haven't thought about any internal strife at this time.

But Yuan Taizuo didn't know that the situation had changed.

When he led Gao Jianwu to lead his troops into the city, Gao Jianwu ordered to seize the city gate, and then put Yuan Taizuo under house arrest.

The palace in the domestic city was originally the royal palace of Goguryeo.

The group took Yuan Taizuo and others to the palace, and then Ezhi Wende finally appeared.

"Wende, what do you mean? Do you want to rebel? ”

"Mo Lizhi, I will tell you a bad news, the Sui army that went south before, he was beyond our expectations. Before I led my army to King Qin in Pyongyang, he had already broken through the city of Pyongyang and the royal palace, and he not only broke through Pyongyang, but also killed the king and all the officials of Pyongyang, including your family. ”

"Now the news of the king's killing is still blocked, the country cannot be without a king for a day, and in order not to cause chaos, I deliberately rushed to Daxing City quietly, and asked Brother Wang to come to the inner city to succeed to the throne, and asked Mo Lizhi to support it."

Yuan Taizuo looked at Gao Jianwu and then at Yizhi Wende, still very shocked.

"Impossible, how could the city of Pyongyang fall, how could the king be killed? It is clear that you want to rebel and make trouble. ”

"Wake up, it's all this time, why do we have to lie to you. Pyongyang is indeed gone, and the king is gone, please don't leave the branch to make a statement, does the branch support the succession of the king? ”

Yuan Taizuo's brain was buzzing.

He looked at this, and then at that, and it always felt unreal.

But now that the domestic city is controlled by Gao Jianwu and Yizhi Wende, and he himself is controlled by them, there is no room for resistance at this time.

The two of them didn't kill him, and they were also afraid that his Yuan clan controlled the vast territory from the Yalu River to the Liao River and hundreds of thousands of troops.

As long as his army is still there, those two still dare not touch him for the time being.

"Okay, if things are really as you said, the king is killed and the city of Pyongyang is broken, then I support the establishment of the king's brother Jianwu to succeed to the throne."

Yizhi Wende smiled, and Gao Jianwu also smiled.

"Great, I will immediately ask people to prepare for the succession ceremony, and ask Mo Lizhi to immediately send a letter to the city lords and generals of Liaodong and other cities, telling them about this, and let them support the new king, control the soldiers and horses, and don't cause chaos."

Yuan Taizuo nodded, and they all responded.

At the end of autumn and August, Gao Jianwu, with the support of Eulji Wendeok and Yuan Taizuo, succeeded to the throne of Goguryeo in the domestic city.
