A simple sand table is placed in the cabin, mainly in the Pyongyang area, including sea routes, some major mountains and cities, and domestic cities are also included on the sand table.

Lai Huer picked up the wooden pole and pointed it at the domestic city. "It is about 120 miles from the domestic city to Pyongyang, and the cavalry can arrive in one day. At that time, the Goryeo army should cooperate inside and outside, and its strength is several times higher than that of us, which is not conducive to our siege."

Yang Yuanqing pondered for a moment and said, "After three conquests of the Sui Dynasty, the strength of the Goryeo Army was greatly damaged. The so-called main force was only more than 100,000. My 30,000 elite troops were not afraid and dared to fight with it."

Lai Hu'er smiled bitterly, "Your Highness, the problem is that the Goryeo people will not fight to the death. They will harass and attack cities or destroy our warships. And they will drag it. A battle will drag it for half a year, and the Sui army cannot drag it down! The Goryeo people have always been strong. Once the Sui army wants to conquer them, they will inevitably have all the people and fight against each other. It is really unlikely that 30,000 troops want to destroy a country. The troops are still too small, and a hundred thousand troops may be able to do it."

Yang Yuanqing nodded, "I really don't have time to stay in Goryeo for a long time. This Eastern Expedition to Goryeo can only be regarded as a surprise attack. At most one month, we must return to Hebei."

"But."."

Lai Huer worriedly: "How to deal with the main force of the Goryeo Army, we need to consider a good plan."

Yang Yuanqing smiled slightly, "I have considered the plan, and Gai Suwen will definitely cooperate with the Sui army's operations."

Lai Hu'er was stunned. He didn't know the profound meaning of Yang Yuanqing's words..."."

The Goryeo Domestic City is located on the banks of the Yalu River in the north, about 100 miles from the capital Pyongyang and less than 100 miles from the Liao River. It is an important strategic city in northern Goryeo.

The domestic city was also the fiefdom of the powerful Yuan family. During the Sui Dynasty's three expeditions to Goryeo, the army controlled by Yuan Taizuo did not fight with all its might. Instead, the army of Goryeo King fought hard, causing heavy losses to the royal army, leaving only less than 30,000 troops.

After the end of the Battle of Goryeo, the situation in Goryeo underwent subtle changes. The army controlled by the Yuan family became the main force of the Goryeo army. Naturally, the powerful Yuan Taizuo became the real power leader of Goryeo.

However, Yuan Taizuo was relatively steady after all. Many things were not revealed. Although he had great power, he still maintained enough respect for King Goryeo.

Moreover, most of the Goryeo ministers were loyal to the Goryeo King, and the Pingyuan Gaoyuan also had enough authority, and the pattern of the king being the superiors and subordinates was not completely broken.

But in just a few months from last winter to this spring, two major events occurred in Goryeo, which was enough to seriously affect the political landscape of Goryeo.

First, Gao Yuan, the King of Goryeo, died of illness last fall and winter. Gao Jianwu inherited the throne. Gao Jianwu was less than thirty years old and had shallow qualifications. Although a group of ministers were loyal to him, he no longer had the authority of the former king Gao Yuan.

The second is that during the battle of Liaodong in the spring, Prime Minister Yuan Taizuo was captured by the Sui army, and Yuan Taizuo's son Yuan Gaisuwen inherited his father's military power and the position of prime minister.

But the ambitious Gassuwen was not as subtle as his father, and used flexible means to seize power. Gassuwen was not. He showed his sharpness and the first thing he did was to set up a messenger army. Every day, government memorials were sent from Pyongyang to the domestic city for him to review.

As a result, two political centers actually appeared in Goryeo, one in Pyongyang and the other in the domestic city. His behavior made the courtiers extremely dissatisfied and rebuked his arrogance.

Gai Suwen's response was to assassinate the most powerful Uncle Wang Gao Quan, and use the Goryeo Hall he founded to monitor court officials, and assassinate five or six ministers who opposed him in a row.

For a time, everyone in Goryeo was in danger, and no one dared to criticize Gasuwen anymore. But more people hated him to the core, and many ministers also began to bribe the killer and prepared to attack him.

Gai Suwen was also afraid of being assassinated, so he simply stopped going to Pyongyang and stayed in the domestic city in the past few months.

That afternoon, a team of people came from outside the domestic city. About a hundred Goryeo soldiers guarded several Sui Dynasty civil servants. From their calm behavior, it can be judged that these people were envoys of the Sui Dynasty.

The envoy was Xie Sili. After he persuaded him to come to Hu'er in Jiujiang County, he received a new order from Yang Yuanqing and rushed to Liaodong without stopping.

In the plan to seize Goryeo resources proposed by Pei Ju, there are two important chess pieces. One is good at water battles and is familiar with Goryeo Lai Huer, and the other is Yuan Taizuo. These two are directly related to the success or failure of Yang Yuanqing's Goryeo strategy.

Today, Xie Sili came to set up the chess piece Yuan Taizuo.

The group came to the city and the leader of the Goryeo soldiers whispered loudly: "Please tell the General that the envoy of the Sui Dynasty came from Liaodong."

Xie Sili also stepped forward and shouted loudly to the top of the city: "Tell Gai Suwen, my surname is Xie, and my name is Xie Sili!"."."."

Gai Suwen was quite worried during this period. He received a news a few days ago that the Sui Dynasty was preparing to release his father Yuan Taizuo back, which really made him worried.

Due to Yuan Taizuo's accidental capture, a battle for military power began within the Yuan family, mainly because Gaisuwen's two uncles participated in the competition.

Gai Suwen did not have an advantage, and finally with the support of his father's several old subordinates, he seized military power and became the heir to his father Mo Lizhi.

Molizhi is an official title, that is, the prime minister of the Central Plains dynasty, but Gai Suwen's inheritance is not very reliable.

On the one hand, King Goryeo has not officially recognized his legal inheritance status so far. According to the inheritance regulations of Mo Lizhi of Goryeo, the next one must wait until the previous Mo Lizhi dies before the next one can inherit it, or the previous Mo Lizhi officially resigns from King Goryeo, and King Goryeo will appoint the next one.

However, Yuan Taizuo's accidental capture made Mo Lizhi's succession hang in the air. On the other hand, Gao Jianwu's hatred of Gaisuwen also made him unwilling to hand over Mo Lizhi's position to Gaisuwen.

It was these two influences that made Gassuwen unable to justify his reputation and could only rely on power to exercise the position of Molizhi on behalf of his father.

It is precisely this reason that makes Gasuwen really worried. Once his father returns, can his military power be preserved?

Power is a sweet poison that makes everyone who tastes its wonderful taste unable to extricate himself. The same is true for Gassuwen. His more than half a year of power has made him unable to give up his power. Even if his father asked for power, he was unwilling to hand over the power.

Gai Suwen once sent two killers into Taiyuan in an attempt to kill his father in prison, but the two killers ultimately failed to find the place where Yuan Taizuo was imprisoned. He had to give up.

At this time, Gai Suwen had already received news from Liaodong. His father had arrived in Yan County and was ready to hand over to Goryeo at any time, which made Gai Suwen extremely anxious. He only dared to send people to Taiyuan to assassinate his father and then frame the Sui Dynasty.

But he did not dare to take action after his father entered Goryeo. In that way, his uncle and several of his father's old generals could not spare him. Gai Suwen worked hard these days, but had no choice but to do anything.

In the room, Gai Suwen was like an ant on a hot pan. He was walking back and forth in the room with his hands behind his back. At this time, a guard reported outside the door, "General, news came from outside the city that a Sui Dynasty envoy has arrived. May I ask if the general will receive him?"

Gai Suwen was shocked and the envoy of the Sui Dynasty actually arrived. He pondered for a moment and asked, "What is the name of the envoy? Do you know?"

"It seems to be called Xie Sili."

This name made Gasuwen say without hesitation: "Please come to my mansion."

Gai Suwen paced the room with his hands behind his back, no longer becoming an ant on a hot pan like in the afternoon. After a little quiet, the arrival of the Sui Dynasty envoy gave him a glimmer of hope.

Especially Xie Sili, of course he knew who Xie Sili was. He was nominally the Minister of War of the Sui Dynasty, but in fact, he was Yang Yuanqing's confidant, and his secret control of the Sui Dynasty was even better than Ziwei Pavilion.

Gai Suwen had a kind of enlightenment that Xie Sili did not come to represent the Great Sui Dynasty. Instead, he came to Yang Yuanqing. His arrival must be related to his father.

About half an hour later, footsteps sounded outside the door, and soldiers immediately reported: "General, the envoy of the Sui Dynasty has arrived."

"Bring him in!"

The door opened. Several soldiers took Xie Sili into the room. Xie Sili looked at the room. If he hadn't understood what the soldiers said just now, he would have thought that he was in the Central Plains, and all the furnishings in this room were exactly the same as those in the Central Plains.

There are large celadon vases and copper incense burners placed in the corner of the house. There are paintings of Wei and Jin style hanging on the wall. Against the wall is a row of books. The books inside are all imported from the Central Plains. At the bottom are two expensive red sandalwood couches, with copper crane lamp posts placed beside the couch and a few candles are lit to make the light in the room soft and bright.

At this time, Xie Sili's eyes fell on the owner of the room. This was a man in his thirties. He was very slender, with a slender waist and a wide back, fair skin, and a pair of slender eyes full of coldness and arrogance.

This person is Yon Gaisuwen, who holds the military power of Goryeo. This reminds Xie Sili of the Goryeo intelligence spy who was arrested half a year ago. He himself confessed that he was Gaisuwen's clan brother. Now it seems that this person is not lying, and the two look very similar.

Xie Sili bowed and smiled, "See General Yuan!"

Gai Suwen nodded slightly, with no smile on his face, "Mr. Xie, please sit down!"

Xie Sili was not polite, so she walked to the couch to sit down. Gai Suwen also sat down. A maid served tea, imitating the Sui Dynasty, and Goryeo also became popular for drinking tea.

Gai Suwen pondered for a moment and asked, "Why did Mr. Xie come?"

"Of course, it came for the matter of Lingzun. His Highness the King of Chu and Lingzun reached an agreement to return Lingzun to the country at the cost of 300,000 stones of food. Lingzun agreed, but His Highness the King of Chu still wanted to ask General Yuan about his opinion."

"What's the meaning!"

Gassuwen stretched his face and asked, "Can I still stop my father from returning to China?"

Xie Sili took a sip of tea and said carelessly: "In fact, whether Ling Zun returns to the country or not has no effect on the Sui Dynasty. If General Yuan does not want Ling Zun to return to the country, it is not impossible."

Gai Suwen narrowed his eyes. Yang Yuanqing was indeed here to make the conditions. He knew very well that he did not want his father to return to China. Gai Suwen did not hide it and sneered directly: "You said! What conditions did Yang Yuanqing offer?"

Xie Sili shook her head, "I don't know what the specific conditions are. The general manager just said that General Yuan will understand soon."
