The Son of Heaven naturally needed to sacrifice to the heavens, and 60,000 people from the Eighth School of the Chinese Army went to Yumen Pass under the command of the Son of Heaven, and Gao Zheng's vanguard also began to march in the direction of Pei Shan.

The Huns naturally will not sit still, they chose to do their best to fight with the Han army, and selected adult men from various small countries to form a subordinate army, so that they can also pull out more than 100,000 troops gathered in the Pei Shan area, Pei Shan as a base camp will naturally not be the first line, so more than 100,000 people along Pei Shan outside the city of more than 100 li, every 20 miles began to build fortifications, a small earthen city rose from the ground, became five or six seemingly impregnable defense lines standing in front of Pei Shan City. Viewed from a high vantage point, these lines of defense made people feel that Pei Shan City was impregnable.

Wu Xu, the vanguard of the Han army, only had 8,000 people in his hands, and it would be very unwise to rashly attack him. Therefore, Wu Xu set up camp in the original valley, and at the same time immediately sent a message to Gao Zheng to inform him of the situation here.

By the time Gao Zheng's army arrived, the Huns' camp had been dug up, and a protracted siege battle was about to begin. Originally, if the supply of the Han army was not a big obstacle, the Huns' ability to fight in cities would not be a problem. However, the Huns seemed to be determined to fight a war of attrition with the Han army, and the Hun army in the trench, no matter how the Han army cursed, was always closed, and the Han army could only forcibly attack the city.

On the one hand, it was closed, and on the other hand, the Hun army sent almost all the men who were good at riding and archery, turning into countless small cavalry teams, and attacked the baggage team many times on the line from Yumen Pass to the big camp. However, this supply line is hundreds of miles long, and it is a wilderness, which is the terrain where the cavalry shows its strengths. In order to ensure the safety of the materials they transported, the Han army could only send cavalry to escort them along the way, and since then, the cavalry of the Han army and the cavalry of the Xiongnu have begun to hedge on different scales for hundreds of miles on the supply line. Although the cavalry of the Han army was elite, in the wilderness warfare, the Xiongnu only harassed but did not attack, which was enough to worry the Han army. The pressure on the defensive side is often much greater on the offensive side.

The simultaneous fighting of the two fronts weakened the siege ability of the Han army on the front line, making it impossible for the Han army to carry out continuous high-intensity attacks on the basis of complete supplies. The attack wave began in January and lasted until the end of February. The Han army had only captured the first front, capturing the entire valley in its entirety. Both the emperor and Gao Zheng couldn't help but re-examine this military operation, and the Xiongnu did have capable people to study the strategy of the Han army. But in this battle, the Han army has already pressed most of the chips, and there is no room for mistakes, so the emperor can only strictly order Gao Zheng to overcome this line of defense as soon as possible.

The enemy who was shrinking made Gao Zheng a little tricky, and he wanted to fight quickly, but he didn't expect to meet the old turtle, which was completely different from the reckless Huns in the past. Then you can only rely on the willpower of the Han army to overcome the defense line one by one. The two sides are in full swing, in fact, the happiest is the Huns, but in Moore's eyes, if the Han army can only attack the next line of defense in two months, then the defense line in front of it can be fully supported until winter, and the Han army's expedition of so far and wide will be vulnerable under the blizzard.

Under the glory of victory, there were the astonishing losses of the Hun army and the horse team, of course, these have been selectively ignored by Kemoor, as long as they can keep the territory in front of them, no matter how much sacrifice is worth it. The Hu Congjun on the front line fought under the sharp blade of the Xiongnu warlords, and ordinary Hun soldiers interspersed back and forth on the empty and bloody battlefield for what their leader called a 'warm home', searching for the grain and grass team of the Han army, and hedging with the Han cavalry.

On the contrary, the nobles of the Xiongnu hid behind the high wall, singing and dancing, and on the banquet, all the nobles raised their glasses to celebrate, and congratulated the Great Khan on his wisdom and martial arts, and of course they could not forget to thank King Zuo Xian for his clever plan, which can make us sit back and relax in Shule City, and other nobles also raised their glasses to celebrate. Faced with this scene, Zali naturally had no choice but to raise a glass. But Zali, as a calm military advisor, naturally has the obligation to tell the Hun nobles, "It's only March now, and you must hold on until August to be considered victorious", but Moore laughed and patted King Zuoxian, "Zali, your defense line, the Han army only broke through one in two months, so calculated, these defense lines, they want to capture them all, at least a year, in the words of the Han people, this is the labor and loss of money, so the Han people's imperial brother has the determination to spend such a time with us?" King Zuo Xian smiled bitterly, "But although it has been a long time, we don't know the specific casualties of the Han army, these Han troops have advanced and retreated, and the two-month attack, each time is a temptation, and they will never attack to the end, so I am afraid that the reason why the Han army has fought for so long in the first line is deliberate."

But Moore Xing may be really bored, he doesn't want to listen to Zuo Xianwang's 'frustrating words', and plans to divert the topic, but the idea of recruiting Gao Zhong actually came up in his mind, "Zhali, do you think it is possible to recruit those Han troops in Shule now?"

Zali looked strange, but seeing that his leader seemed reluctant to mention the issue, he followed the leader's train of thought. I couldn't help but ask, "Great Khan, what are you? Why do you suddenly think, you have to know that they have a special identity, but they may not necessarily fall?"

But Moore shrugged his shoulders and said, "It's nothing, just try it, if they fall, you can humiliate the Han army, if not, it is estimated that it will not be long before it dies, or rather, I want to see if those Han soldiers are dead, after all, you also know, five months, since the beginning of winter, it has been five months, I am curious, whether the Han army has all starved to death." When they starve to death, they can take their heads to intimidate the Han army on the front line, and it is also interesting to let Gao Zheng look at the death of his son. ”

Zali rolled his eyes, this idea was very evil, and he arched his hand and said, "In this case, the subordinates are naturally willing to accompany the Great Khan to this experience and see if the Han army is dead." ”

When the Hun nobles on the side heard this, they also said that they would follow Ke Moore to Shule to recruit Gao Zhong and others, but Mo Er laughed, "Okay, let's go with me to have a look." I think that kid was the hardest and tightest at the beginning, but now let's see if they still have such a hard backbone."

Zali thought for a moment, "Do you need to bring siege engines?

Unexpectedly, Ke Moore waved his hand, "No need, now Shule is insignificant, there is no need to waste time for them, let's go, let's go, the distance of two hundred miles is not short!"
