Early the next morning, Guo Song took his sons Guo Jincheng and Xue Qing to the north about forty miles away from Yunzhong County. ”

Guo Jincheng immediately said: "Han Gaozu six years, Han Wangxin rebelled in Yunzhou, and colluded with the Huns, seven years, Han Gaozu led 300,000 troops to drive the expedition, even the battle, at this time the sky fell heavy snow, Han Gaozu was carried away by the victory, regardless of the obstruction of his subordinates, personally led thousands of forwards to pursue the Hun army, but was surrounded by the Hun army in the north mountain, with Chen Ping's strategy, bribed the Yan family, seven days and seven nights before being able to escape. ”

Guo Song smiled slightly: "There are a lot of things that go against common sense in this story, can you think of it?" ”

Guo Jincheng was stunned, shook his head and said, "The child doesn't know." ”

Guo Song said lightly: "First, why did Liu Bang choose to go to Han Wangxin in winter? In fact, the reason is very simple, the grassland is snowing heavily in winter, and the Xiongnu cannot come to the aid of Han Wangxin, Liu Bang will choose to go out in winter in order to avoid the Xiongnu army, but he can't imagine that hundreds of thousands of Xiongnu troops have been ambushed in Yunzhou in advance, which shows that there are spies in the imperial court, and the battle plan of the Han Dynasty has been leaked and known by the Huns. ”

Guo Song continued: "The Han army is only a few thousand people, and the Xiongnu have an army of 400,000, why don't the Xiongnu go all out to attack the mountain and capture Liu Bang alive?" Could it be that Liu Bang's cavalry could go up the mountain, but the Hun cavalry could not go up?

There is another doubt, the 400,000 Hun army marched south in winter, how could Mao Dunshan Yu bring a woman with the army, even if he had the privilege and brought a concubine, how could the Han army know? ”

Xue Qing couldn't help but add: "The history books say that Mao Dun and the Yan clan went in and out of the military camp, and their expressions were intimate, and they were seen by the Han army on the mountain, so they came up with a plan. ”

Guo Song laughed, "A county town has a population of only tens of thousands, and how big the military camp of 400,000 troops will be, do you want to get it?" Han Jun can still see the woman's appearance clearly, and he still knows that this woman is Mao Dun's concubine? What's even more incredible is that Chen Ping can still pass through the overlapping Hun camps to meet Mao Dun's beloved concubine, Mao Dun still doesn't know? Chen Ping is such a cow, why didn't he just kidnap the concubine Mao Dun back to Baishan Mountain? This is simply treating the Hun cavalry as a scarecrow. ”

Guo Jincheng and Xue Qing were red-faced when they heard this, there were indeed too many loopholes in it, Guo Jincheng asked, "What is the truth?" ”

Guo Song shook his head, "No one knows the truth, but one thing may be certain, Mao Dun is by no means a reckless man, he knows that if he kills Liu Bang, the crown prince of the Han Dynasty will immediately ascend the throne, and the Xiongnu still can't get anything, only by reaching some kind of agreement with Liu Bang and putting Liu Bang back, the Xiongnu can get greater benefits." ”

Xue Qing thought for a while and said: "Could it be that there is no Yan clan at all, Chen Ping actually went down the mountain to see Mao Dun, and the two sides reached an agreement, and Mao Dun let Liu Bang go back." ”

Guo Song laughed, "It sounds like that, but in fact, you have all been induced by me, in fact, the real explanation, there is no siege of Han Gaozu Bai Mountaineering at all, with Liu Bang's identity as the Son of Heaven, he will only sit in Taiyuan and command the overall situation, how can he lead the front army to attack Yunzhou and put himself in danger?" That's the biggest loophole.

In order to cover up this loophole, they made up a story full of loopholes to explain it, which makes people feel confusing, but they ignore the fundamentals, do you understand? Even if there is the siege of Baideng, it will never be Liu Bang who is besieged, but should be his subordinate generals, and in the end, the Xiongnu withdrawal was also defeated by the reinforcements of the Han army, which is by no means a woman's words. ”

Guo Song saw that the two of them lowered their heads and pondered silently, and said with a slight smile: "I don't mean anything else when I tell you this, I just want you to learn to think, only in continuous thinking, your mind will gradually mature." ”

A group of people put their horses at the foot of the mountain and climbed the Baishan Mountain, there is a beacon on the Baishan Mountain, standing on the beacon, the field of vision is broad, you can look at the far place, there are enemy cavalry attacking dozens of miles away, you can also clearly see.

Guo Song stood on a high place, pointed to the faintly visible peaks in the distance and asked Fengsuihuo, "Is the Great Wall in the distance?" ”

Huo Chang hurriedly said: "It is the Great Wall, which was rebuilt during the Sui Dynasty, but it has been destroyed a lot by the Turks and the Hui, and it can't stop the Hui cavalry from going south." ”

"If the enemy's iron cavalry goes south, will it bypass Baishan Mountain and attack Yunzhong County?" Guo Song asked again.

"In fact, there is this possibility, mainly at night, no matter how much they detour during the day, we can find it from afar, but if it is night, a little farther away, we can avoid the beacon, and the night is indeed more troublesome."

Guo Song asked his son with a smile: "If you are the commander, how do you defend against the enemy's sneak attack at night?" ”

Guo Jincheng lowered his head and thought about it: "The child thinks that as long as it is dark, the city gate must be closed and patrols must be strengthened on the city. ”

Several accompanying generals praised the high wisdom of the prince, and Guo Song also nodded, it was not easy to think of this step at the age of seven.

But Guo Song didn't praise him, just said lightly: "This is just a qualified guard's approach, not the coach's thinking, as a coach, early warning is the first priority, you can't wait for the enemy to kill in front of you to deal in a hurry, you have to consider this problem from the direction of early warning." ”

Guo Song saw that his son was still a little confused, so he smiled and said to Zhang Yun: "General Zhang, you are the scout commander, you come to tell him." ”

"Obey the order!"

Zhang Yun stepped forward and saluted, and said to Guo Jincheng with a smile: "The prince may not know the way of war of the nomads, once he decides to go on the expedition. First of all, they want to gather troops, the tribes of the grassland are widely distributed, and they must send messengers with wolf head orders to the tribes to notify the dispatch of troops, and then the troops from all over the country rush to the tooth tent to gather, this back and forth, as little as 20 days, more than a month, which actually gives us early warning time. ”

Guo Jincheng nodded, "I understand, but the premise is that we have spies on the grassland, otherwise we still don't know anything." ”

"That's the key."

Guo Song said on the side: "How do you plant spies in the grassland?" This has always been a difficult point for the Central Plains Dynasty, but the Sui Dynasty did a good job in this regard, the Turkic envoy at that time, Changsun Sheng, accumulated a lot of experience for us, it used merchants, enemy opponents, and the Sinicized Hu people, mastered a lot of important information, laid a solid foundation for the Sui army to defeat the Turks, and we can make use of these experiences. ”

"The child understood the meaning of the father's warning."

Guo Song said: "The Han Dynasty's attack on the Xiongnu did not rely on early warning, but took the initiative to go on a northern expedition, go deep into the grassland, and grasp the initiative. ”

........

At night, Zhang Yun came to the Chinese military tent, and his own soldiers brought him into the big tent, Zhang Yun knelt down on one knee and hugged his fists and said: "See Your Highness!" ”

Guo Song was still staring at the grassland map on the table, and after a long time, he said slowly: "Sijie is split, and the Hui is likely to annex the various departments of Sijie and become strong again." ”

Zhang Yun has followed Guo Song for many years, how could he not understand the mind of the lord, and he had already guessed the lord's intention in Bai Mountain's words today.

"Does Your Highness want to take the initiative to attack Huifu?"

Guo Song nodded and said: "If you want to attack Hui, the key is intelligence, I have written to Li An, the former chief steward of the imperial merchants, he has a caravan in the city of Xishou, and he is very familiar with the various departments of Sijie, I have asked him to arrange for the caravan to go north to investigate the situation of Sijie for me, but we can only rely on ourselves to return to Hui." ”

Zhang Yun hugged his fists and said: "Please order you to go north!" ”

"This is the real purpose of bringing you to Yunzhou, I hope you can lead a scout army to the Turkic tent to find out their intelligence, the risk is very high, ordinary scouts can't do it, so I can only let you go."

"I will definitely be able to complete the task and come back."

Guo Song took out a map and handed it to him, "This is a very accurate grassland map, you can pretend to be a gold digger to go north, I asked Li Tingshi, there is a gold digger in the city, the head of the household has more than ten years of gold panning experience, he will take you north, you go to Li Tingshi for specific matters, I have already instructed him, he will arrange it for you." ”
