Liu Yu smiled slightly: "So, they can sit on the mountain and watch dogs bite dogs, and then welcome my Northern Expedition King of the Jin Dynasty. That is their own team."
Murong Lan's pink face sank, and her hand unconsciously pressed on the handle of the knife: "What are you talking about, you want to break your promise and offend our Dayan?"
Liu Yu smiled and shook his head: "Don't be nervous, it's just a joke. It's impossible for me to decide the Northern Expedition. Besides, if it were up to me, I wouldn't break my promise."
Murong Lan's expression softened slightly and she moved her hand away from the handle of the knife: "That's more or less the same. However, what you said makes sense. The Han people in the north have experienced countless wars over the years and have long developed the habit of not acting rashly. , they defended themselves during the war and did not help each other. In this way, it really depends on the outcome of the Battle of Yecheng. Humph, but it doesn't matter. If they don't come to help us, they can't help Fu Pi. How can a small isolated city survive for ten to eight years?"
Liu Yu said seriously: "A long-term siege may not be beneficial to you. You seem to be very powerful now because when you first raised the army, Xianbei and Dingling people joined in large numbers, and Qin State suffered a disastrous defeat in Feishui. People's hearts were unstable for a while. The Han people were waiting and watching, and the Di people were It is not enough to surrender the important towns, so there is a power vacuum in a large number of villages. But once you fail to attack Yecheng for a long time, there will inevitably be changes internally. Moreover, your army now has more than 200,000, which will consume huge amounts of food. Once the people in the countryside If the Han people are unwilling to fully support your military rations, there will definitely be a food shortage within half a year."
"After all, Yecheng has been run by the Qin State for many years. It is regarded as the fundamental important town in Guandong. The food can supply at least a year's needs. And it is not alone. Youzhou and Pingzhou in western Liaoning outside the Great Wall all have their hearts attached to the Qin State, not to mention the representatives outside the Great Wall. When Fu Jian destroyed the Dai Kingdom, Liu Kuren, an old minister of the country, was grateful for his loyalty and made him the commander outside the Great Wall to guard the Tuoba family's hometown. During the Yongjia Rebellion in the Western Dynasty, these fierce grassland nomadic troops rescued the Western Dynasty many times. I think Liu Kun, who was in the imperial court, and Liu Kuren would do the same thing."
Murong Lan softly said "Oh": "Liu Yu, didn't you say that we Hu people are all human-faced and beast-like, fearful of power but not moral? When the Central Plains are strong, they will surrender, but when they are weak, they will counterattack. How do you talk about this Liu Ku?" Benevolence, but you say he is a loyal person? Are you deceiving yourself and others?"
Liu Yu laughed: "That's not the case. When Liu Kuren was in the Tuoba clan of Dai, he was their southern leader and commanded the tribes in Monan. When Fu Jian led his army to destroy Dai, he led his troops to fight hard. It blocked the Qin army for a while, but due to internal strife in the Tuoba family, Tuoba Yanjun assassinated his father Tuoba Shi Yijian, which led to the destruction of Dai. He had no choice but to surrender to the Qin state. Fu Jian did not kill him, but let him He leads the original Daiguo tribe as the Eastern Lord."
"It turns out that Dai's sworn enemy, Liu Weichen, the leader of the Xiongnu Tiefu tribe, as the right lord, commanded his tribe and settled in the Hetao area. This Liu Weichen is really unfaithful. He has repeatedly fought against Yan and Rebellions and subjugations among the Qin Kingdom are unpredictable, but when the dynasty was finally destroyed, he was the leader who led the Qin army into the grassland, so logically speaking, he should be the one who made the first contribution."
Murong Lan was surprised: "Liu Yu, how come you know so much about things on the grassland?"
Liu Yu smiled slightly: "If we want to regain the entire Central Plains in the future, we will inevitably have to deal with these grassland tribes who have been isolated for hundreds of years. During the Western Dynasty, the Tuoba clan provided great assistance to Liu Kun, but it was only due to the civil strife in the clan that they stopped. The contact led to Liu Kun's failure. Therefore, from our perspective in Jin Dynasty, this is a force that can be used. They are old friends. Naturally, we need to know their movements. Now all the Tuoba clan has been moved to Fu Jian Within the pass, Liu Kuren has become the leader on the grassland, and his movements are of vital importance."
Murong Lan sneered: "But why does Liu Kuren want to help Qin? He also destroyed his own country for Qin back then. Although Fu Jian did not kill him and let him lead the old army, it would be the same as my elder brother. He would be destroyed. Do you think you need to be grateful if you take over someone else's country and give them some benefits? When our country of Great Yan existed, we treated him generously. That Tuoba Shi Yijian later became Ke Dun, the leader of the grassland. Madam, she is equivalent to the queen of your Han people, and the daughter of our Murong clan."
Liu Yu smiled and said: "But Liu Kuren's mortal enemy is not the Qin or Yan states in the pass, but Liu Weichen of the Tiefu tribe. The vendetta between the Tiefu tribe and the Xianbei tribe has been going on for hundreds of years on the grassland. , to the death, Liu Weichen once wanted to slaughter all the Xianbei people in the past, but Fu Jian stopped him. Fu Jian was afraid that Liu Weichen would go back to massacre after the Qin army left, so he drove him far away to Hetao In this land, I want to be the master of the west, and use Liu Kuren as the master of the east. I want to contain Liu Weichen."
"Now that the Qin State has collapsed, Liu Kuren will face strong pressure from Liu Weichen again. The Yan State has been destroyed for many years, so it may not be reliable. However, the Qin State has been protecting itself for so many years. It is naturally self-evident which side to help. If the fierce and skilled Xianbei cavalry of the Tuoba clan join the battle, then your eldest brother may not be able to win."
Murong Lan's expression became more solemn and she sighed: "You guessed it right. In fact, what eldest brother is really worried about is the Tuoba Xianbei outside the Great Wall. They have many war horses and come and go like the wind. Once they enter the Hebei Plain, That is even more powerful than a tiger. It is not difficult for our Murong clan's cavalry to hit them head-on, but these people are very mobile. If they do not fight head-on with our armored cavalry, but instead intercept our food routes in various places, it will be terrible. It’s going to be big trouble.”
Liu Yu laughed: "So, your eldest brother's situation doesn't look so good. If you can't take Yecheng quickly, the whole of Hebei will be at risk of losing something. Murong Lan, the situation has been analyzed. I advise you Don’t think too much about Yuxi, it’s best to go back and help your elder brother find a way to deal with Liu Kuren.”
Murong Lan curled up the corners of his mouth, looked around, and clearly pricked up his ears to listen. Liu Yu's expression changed. Murong Lan was obviously checking to see if anyone was lurking around and eavesdropping. After a long time, Murong Lan relaxed. He lowered his voice and said: "Xie Xianggong is really a gentleman and did not send anyone to eavesdrop on our conversation. Now, I can tell you one thing, Liu Yu, you must not tell others."
Liu Yu looked at Murong Lan's serious expression: "You tell me, I won't tell others."
Murong Lan whispered: "My eldest brother has long expected what you are thinking. This time he left Yecheng without even taking his son with him, but he did take one person with him. This person is Tuoba Daiguo. The emperor’s eldest grandson, Tuoba Si.”
