Cao Liang set the tone for this attack to be a sneak attack, taking advantage of the opportunity that the Huns thought that it was impossible for the Wei army to continue north in a short period of time and neglected to take precautions, unexpectedly, attacked it unprepared, and took Daling, the location of the Xiongnu in the middle, and Qi County, the location of the Xiongnu on the right, in one fell swoop.

When dividing the troops, Cao Liang arranged the Yue cavalry battalion and the infantry battalion as the East Route Army to attack Qi County, and arranged the Tun Cavalry Battalion and the Changshui Battalion as the West Route Army to attack Daling.

Relatively speaking, the strength of the Xiongnu on the right was stronger than that of the Xiongnu in the middle, so Cao Liang deliberately handed over the task of attacking the fortification to the Yue cavalry battalion and the infantry battalion, with Deng Ai Yanghu and Du Yu as the command.

The Pingbei General's Mansion moved with the Western Route Army, advancing north along the west bank of Jiuze and attacking Daling.

The Eastern Route Army was advancing north along the east bank of Jiuze, and since it was a sneak attack, the whole process of marching was to die down and advance quietly.

Due to the way to Qi County, the way to pass through Wu County, Zhongdu, Jingling and other three counties, in order to avoid being discovered by the Huns, Deng Ai deliberately sent a cavalry unit as the vanguard, this vanguard army all disguised and changed, changed into the Huns' war horses and costumes, anyway, these equipment is not lacking in the Wei army at all, how much to have.

However, the clothes and outfits can be changed, but the accent language problem cannot be solved, after all, there are almost no people in the Wei army who understand Xiongnu dialect and can speak Xiongnu dialect, so Deng Ai deliberately recruited some Xiongnu troops to act as guides before going on the expedition.

So from the outside, this vanguard force is no different from the Huns, and they are under the banner of the Huns, and it is enough to confuse the Huns along the way.

The three county towns along the way, either have been occupied by the Huns or were sacked by the Huns and then gave up, in order to avoid startling the snake, the East Route Army rushed to Qi County this time, and walked all the way, bypassing the three county seats, hiding their whereabouts along the way, not giving the Huns a chance to find out.

The Eastern Route Army completely chose to march at night, and throughout the night, it was marching non-stop, and when it came to daytime, the team would all stop and choose a hidden place to hide and rest.

In order to achieve the concealment of the march, this time the Wei army attacked, using the way of light advance, in addition to each person carrying seven days of dry food, other baggage, all handed over to the follow-up baggage battalion, even the daily camping, there is no tent to live, all are wild camping.

However, because the Eastern Route Army adopted a black-and-white reversal of the way of work and rest, marching at night and resting during the day, and now it is summer, the weather is hot, and when they rest every day, the Wei soldiers have to choose to cool off in the shade of trees, and it doesn't matter if there is a tent or not.

In order to avoid lighting the cooking smoke and being discovered by the Huns, the Wei army did not bring men and did not light fires along the way, and relied on water and dry food to satisfy hunger.

Sleeping in the open all the way, but the Wei soldiers did not have any complaints, everything was for victory, and at this point, the consciousness of the Wei soldiers was quite high.

In order to maintain the consistency of the march of the synchronized troops, the Yue cavalry battalion deliberately suppressed the speed, otherwise, such a section of the road, the Yue cavalry battalion could arrive in almost a day.

However, in order to rush to Qi County as soon as possible and give the Xiongnu a surprise blow, the Wei infantry also increased the speed of the march, according to the current marching speed, the Wei army only needs three nights to reach Qi County.

Even if Qi County is only a county-level city, if the garrison is sufficient, if the Wei army wants to attack, it will never be able to take it in a short time.

And the main force of the Huns is currently under the city of Jinyang, which is only more than a hundred miles away from Qi County, and if the cavalry comes back, it will only take half a day at most.

So this is also where Liu Meng has nothing to fear, even if Qi County is attacked, they have enough time to come back to help, so that they can do both offense and defense.

If the Wei army wants to capture Qi County, it must use the means of surprise attack, taking advantage of the weak strength of the Huns, the empty defense and defenseless, to take Qi County and Daling, the two Hun base areas, in one fell swoop, so as to grasp the initiative of the war situation.

And once they fall into a dilemma under the city, that is the worst situation, so Deng Ai Yanghu and they must avoid this situation.

The vanguard units disguised as Xiongnu soldiers did play a considerable role, when marching at night, they were guides, leading the Wei army to move forward, and during the day, when the army rested, they became sentry posts, heavily guarded on all roads, and forbade anyone to approach the Wei camp.

The vanguard troops were indeed tired of performing tasks day and night without sleep, but fortunately, they only lasted for three days at most, and after three days, when they arrived at the city of Qixian, they could complete the task and sleep well.

In the early morning of the third night, the vanguard troops who were acting as guides in front suddenly stopped advancing, and Deng Ai couldn't help but wonder, could it be that there was a Hun sentry in front?

Before the people he sent out stepped forward to inquire, Sima of the vanguard force had already sent someone to report back, and the reason why they did not advance anymore was because the Wei army had reached the city of Qixian County, and at this moment the vanguard army was less than a mile away from the city of Qixian County, and by the moonlight, even the dark outline of the city wall of Qi County could be seen.

In order to avoid startling the snakes, the vanguard Sima was discovered by the defenders in the city, so they stopped a mile away from the county seat and went back to report to Deng Ai to see what he should do.

Since it was Qi County in front, Deng Ai immediately ordered the whole army to stop advancing and stand by in place, and at the same time urgently summoned Yanghu and Du Yu to discuss how to attack Qi County.

Yang Hu and Du Yu arrived at the first time, and together with Deng Ai, the three of them discussed the method of attacking the city.

Of course, the cavalry can't count on it when attacking the city wall, and the infantry battalion and the shooting battalion will be the main force of the siege, but it is still difficult to take Qixian County unexpectedly.

The large-scale attack of the army is bound to attract the attention of the defenders in the city, even if most of the defenders in the city are asleep at the moment, there must be still the remaining army, once they are alerted and put into defense, then the Wei army's sneak attack is likely to be in vain.
