Liu Yu smiled slightly: "So, they can sit on the mountain and watch the dog eat the dog, and then welcome my Northern Expedition King Division, that is their own team." ”

Murong Lan's face sank, and her hand unconsciously pressed the handle of the knife: "What are you talking about, you want to destroy the promise and offend our Dayan?" ”

Liu Yu smiled and shook his head: "Don't be nervous, just kidding." I can't decide on the Northern Expedition, and besides, if I can, then I won't break my promise. ”

Murong Lan's expression eased slightly, and his hand moved away from the hilt: "This is about the same." However, what you said is also reasonable, the Han people in the north have experienced countless wars over the years, and have long developed the habit of not acting rashly. Hmph, but it's nothing, they don't come to help us, and it's impossible to help Fu Pi, a small lonely city, can it last for ten or eight years? ”

Liu Yu Zhengse said: "A long-term siege may not be beneficial to you. Now your momentum looks very big, because when you first started the army, Xianbei and Ding Ling joined in large numbers, and the Qin State was defeated in Huishui, and the people's hearts were unstable for a while, the Han people waited and watched, and the Di people were not enough to retreat to the important towns, so a large number of rural power vacuums, but once you attack Yecheng for a long time, there will inevitably be internal changes. Moreover, you now have more than 200,000 troops, and there will be a huge consumption of food, and once the Han people in the countryside refuse to fully support your military rations, there will inevitably be a food shortage within half a year. ”

"After all, Yecheng has been operated by the Qin State for many years, and it is thought that it is a fundamental and important town in the eastern part of the country, and the grain can be used for at least one year. And not alone. Youzhou and Pingzhou, Liaoxi, both outside the Saiwai are devoted to the Qin State, not to mention Liu Kuren, the old minister of the Daiguo outside the Saiwai, when Fu Jian destroyed the Daiguo, he was grateful for his loyalty and righteousness, and let him guard the Tuoba clan's hometown as the commander of the Saiwai. During the Yongjia Rebellion of the Western Dynasty, these fierce steppe nomadic armies rescued Liu Kun during the Western Dynasty many times, and I think this Liu Kuren would have made the same move. ”

Murong Lan said softly: "Liu Yu, didn't you say that our Hu people are all human-faced beasts, afraid of power but not virtuous, when the Central Plains is strong, they will be attached to it, and when they are weak, they will counterattack and count, how can you talk about this Liu Kuren, but he is a loyal person?" Are you deluding yourself? ”

Liu Yu laughed: "It's not like this, when Liu Kuren was in the Tuoba clan of the Daiguo, he was their southern lord, commanding the people of Monan, when Fu Jian led the army to destroy the dynasty, he led his troops to fight and blocked the Qin army for a while, but because of the internal strife in the Tuoba clan, Tuoba Yanjun assassinated his father Tuoba Shi Yijian, which led to the destruction of the Daiguo, and he could only surrender to the Qin State, Fu Jian did not kill him, but let him lead the original Daiguo tribes, as the eastern lord. ”

And Liu Weichen, the sworn enemy of the original Daiguo, the leader of the Xiongnu Tiefu Tribe, as the lord of the right department, led his own people and settled them in the Hetao area. This Liu Weichen is really faithless, and has rebelled against impermanence between Yan and Qin many times, but in the end, when the dynasty was destroyed, it was he who led the Qin army into the grassland as a guide, and it stands to reason that he should be the first hero. ”

Murong Lan was surprised: "Liu Yu, how come you are so clear about things on the grassland?" ”

Liu Yu smiled slightly: "If you want to recover the entire Central Plains in the future, you will inevitably have to deal with these grassland tribes that have been isolated for hundreds of years. Therefore, in our Dajin view, this is a force that can be used, and it is an old friend, so it is natural to know their movements. Now all the clans of the Tuoba clan have been moved to Guannei by Fu Jian, and Liu Kuren has become the leader of the grassland, and his movements are very important. ”

Murong Lan sneered: "But why does this Liu Kuren want to help Qin Guo? He also destroyed his own country for the Qin State back then, although Fu Jian didn't kill him and let him lead the old department, but this is the same as my eldest brother, destroying other people's countries, and giving some benefits, does this need to be grateful to Dade? When my Dayan Kingdom existed, it was not thin for him to represent the country, and that Tuoba Shi Yijian's later Kedun, that is, the wife of the leader of the grassland, is equivalent to the queen of your Han people, or the daughter of our Murong clan. ”

Liu Yu said with a smile: "But Liu Kuren's mortal enemy is not the Qin State or the Yan State in the Guannei, but Liu Weichen of the Tiefu Department, the vendetta of the Tiefu Department and the Xianbei Department has lasted for hundreds of years on the grassland, and it is endless, when the dynasty was destroyed, Liu Weichen once wanted to slaughter the Xianbei people of all the tribes, but he was prevented by Fu Jian and failed to succeed, Fu Jian was afraid that Liu Weichen would take advantage of the Qin army to leave and then go back to slaughter, so he drove him far away to the land of the Hetao, and when he was the lord of the west, and used Liu Kuren as the lord of the east, he wanted 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, and it may not be reliable, and the Qin State has been protecting itself for so many years, so which side to help, it is naturally self-evident. If the fierce and warlike Xianbei cavalry of the Tuoba clan joins the battle, then your eldest brother may not be able to win. ”

Murong Lan's face became more and more solemn, and he sighed: "You guessed it right, in fact, what the eldest brother is really worried about is these Tuoba clan Xianbei outside the plug, they have a lot of war horses, they come and go like the wind, once they enter the Hebei Plain, it is like a tiger with wings, it is not difficult for our Murong clan's iron cavalry to fight them head-on, but these people are very mobile, if they don't fight our armor and cavalry head-on, but divide the way and intercept our various grain routes, it will be a 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 gaining and losing." Murong Lan, the situation has been analyzed, I advise you not to think too much about the jade seal, and go back to help your eldest brother find a way to deal with Liu Kuren, which is the best policy. ”

Murong Lan hooked the corners of her mouth without hesitation, looked around to the left and right, and obviously pricked up her ears to listen, Liu Yu's expression changed, Murong Lan was obviously probing whether there was anyone lurking around to eavesdrop, and after a long time, Murong Lan breathed a sigh of relief, lowered her voice and said: "Xianggong Xie is really a righteous gentleman, and he didn't send someone to eavesdrop on us." Now, I can tell you one thing, Liu Yu, you must not tell others. ”

Liu Yu looked at Murong Lan's serious expression: "You say, I won't tell others." ”

Murong Lan said in a low voice: "My eldest brother has long expected these things you think, this time he went out of Yecheng, and he didn't even bring his son, but there was one person with him, and this person was the eldest grandson of the emperor of Tuoba Daiguo, Tuoba Si. ”
