The next day, before dawn and the moon was still hanging high in the air, Xia Yu led the mobile troops to set off. In this operation, the main force led by Bai Pengfei was just a decoy, and the team led by Xia Yu was the real killer move, like a sharp dagger that was inserted into Zheng Xiu's throat. In order to achieve this combat goal, Xia Yu and the others must rush to Qingyan City as quickly as possible at any cost.

In fact, another reason why Xia Yu made up his mind to take the initiative to attack Qingyan City is that according to the intelligence of the confidential troops, Zheng Yuan is leading his 70,000 infantry to assemble in the direction of Qingyan City, if Zheng Yuan also arrives in Qingyan City, 70,000 infantry and 30,000 cavalry will join forces, and Qingyan City will have 100,000 troops, then Tongming City will really have no chance at all.

"Woo-"

Xia Yu led the troops to advance rapidly among the dense woods, and the three-dimensional maneuvering device spewed out long strips of white smoke, like a tail cloud left by an airplane in the air. The dust crystals embedded in the three-dimensional motorized device emit a bright multicolored light, like the tail lights of a car. If you look down from the sky, you can see colorful rainbows flying through the dark forest, like long snakes that glow.

The "serpents" were arranged in an arc of ten, and although the arc team occasionally changed due to the obstruction of the trees, the whole remained the same, and in the midst of the lush forest, they advanced at a speed no less than that of a galloping horse, but still kept the queue intact. One can imagine how elite this unit is. This small team of four hundred people, so to speak. It's the most elite elite in Tongming City.

At the front of the team, Xia Yu and Lu Yue took the lead. Xia Yu's gaze was firmly fixed on the dark ahead, the white eyes that had been opened long ago could make him see farther, and the sound of the whistling wind in his ears made his gaze pass through the lofty mountains in front of him and fell far ahead.

In this way, Xia Yu and his party quickly approached Qingyan City non-stop, and finally at dawn, they walked out of the dense Beishan Forest and saw the majestic Qingyan City under the mountain. And this time. The soldiers who accompanied the army were already tired and sweating profusely. Out of breath.

They had slept for less than four hours the previous night, marching from midnight until dawn, during which time no one had eaten a mouthful of dry food or drunk a sip of water. But despite this, when Xia Yu suddenly ordered to stop the march. The soldiers all stopped at once. There was still no confusion in the queue. Although everyone was exhausted and hungry, the soldiers of these three-dimensional mobile units were still like javelins. Standing straight in front of Xia Yu, they looked at Xia Yu's gaze as they were still as indestructible as their war knives.

Xia Yu looked at the team he led with a scrutinizing eye, and couldn't help but nod with satisfaction: "Well, Bai Pengfei, this kid really has a set of military training, not bad." ”

After Xia Yu did not come back, Xia Xue was responsible for expanding the army and consolidating the city defense, and Bai Pengfei was responsible for training, and almost all the 10,000 defenders of Tongming City were trained by Bai Pengfei. Especially the four hundred elites led by Xia Yu now, they were originally the elite disciples of the Xia family and the Bai family, and after Bai Pengfei's special training, they were even more refined. The wolf-headed army led by Zheng Yuan is indeed the division of the tiger ben, but if it is only about people, Xia Yu's three-dimensional mobile troops are not much worse than them.

"Listen to the order, rest in place, and be ready to attack at any time!" Xia Yu gave a loud order, and then, he and Lu Yue quietly approached Qingyan City.

Qingyan Castle is a city built on a mountain, it is surrounded by plains on three sides, east and west, and only a cliff next to the north mountain in the south. This cliff is dozens of meters high, almost straight up and down, no one would have thought that one day the enemy army would fight down from this place, because whether it is the residents of Qingyan City, as well as other outsiders who have been to Qingyan City, almost everyone agrees that the high mountain and deep North Mountain will be the best protection for the south of Qingyan City, and no army can pass through the North Mountain and attack Qingyan City from the south. Even Xia Yu himself had recently thought that the southern side of Qingyan City was invulnerable. It is precisely for this reason that the city wall on the south side of Qingyan Castle is built low and low, and compared to the strong and tall city walls in other directions, the city wall on the south side of Qingyan Castle is simply a small earthen wall with broken stone tiles.

Xia Yu and Lu Yue came to the edge of the cliff, and the two of them lay on the dense grass, quietly observing the Qingyan City below, from the top of the cliff, they could just see the entire Qingyan City at a glance. And Xia Yu's white eyes are comparable to a "human flesh telescope", so every move in Qingyan City at this time is all under Xia Yu's eyes.

Xia Yu first looked at the guards in the south of Qingyan City, as he expected, the guards in the south of Qingyan City were pitiful, almost symbolically sent a dozen or so people to guard, and the three directions of east, west and north were different, each city wall was heavily guarded, and a group of soldiers wearing armor and holding spears patrolled the city wall in an orderly manner.

Then, Xia Yu's gaze shifted to Qingyan City, and he was suddenly surprised to find that the 30,000 cavalry stationed in the city were rapidly assembling.

"Zheng Xiu is assembling troops, could it be that Peng Fei has already arrived?" Xia Yu frowned and thought for a moment. "No, Pengfei's 20,000 troops are almost all infantry, and it is impossible to go so fast, even if it is noon at the earliest, they can cross the North Mountain. In this case, Zheng Xiu must want to march to Tongming City when he mobilizes the army!"

"Then what should we do?" next to him, Lu Yue asked.

"The plan remains the same. Zheng Xiu took the initiative to transfer troops out of Qingyan City, which is a good opportunity for us. Xia Yu still looked at Qingyan City below.

However, if Zheng Xiu's troops reached the gourd pass of Beishan before Peng Fei, Peng Fei's 20,000 horses would probably all be eaten by Zheng Xiu. Even if Peng Fei blocked Zheng Xiu's attack and lost the favorable terrain of the gourd pass, he would not be able to hold back Zheng Xiu's cavalry at all. Once we start attacking Qingyan City, what if Zheng Xiu gets the news and rushes back to the rescue? Lu Yue's face was very stern, and her tone was very solemn.

[Gourd Pass] is a key point of Xia Yu's battle, it is the mountain pass in the north of Beishan, shaped like a gourd, so it is called the gourd pass. The terrain of the gourd pass is very suitable for ambushes, and Bai Pengfei can easily drag Zheng Xiu's cavalry as long as he tightens the exit of the gourd and the mouth in the middle.

Starting from Tongming City, turning over the entire North Mountain, after coming out of the gourd pass in the north of the North Mountain, there is an endless plain, which is generally called the [Northern Plain] by the patriots. Wind Helmet City and Qingyan City are located at the north and south poles of the Northern Plains, and almost all of them are plains between Wind Helmet City and Qingyan City, and there are even very few hills. This is why Zheng Xiu's cavalry will arrive in Qingyan City so quickly.

In Xia Yu's battle plan, Bai Pengfei had to take the Hulu Pass in order to rely on the favorable terrain there to drag Zheng Xiu's cavalry, otherwise all his efforts would be wasted.

Listening to Lu Yue's words, Xia Yu was silent for a while. Then he retracted his gaze, turned his head, and smiled at Lu Yue, his tone was very affirmative: "I believe in Peng Fei, he can definitely take the gourd pass in front of Zheng Xiu." ”

Zheng Xiu's 30,000 iron cavalry is worthy of being Zheng Guo's elite division, but with a stick of incense, the entire 30,000 people have all been assembled, and the team is arranged on the streets of Qingyan City, like a torrent of steel, and the scene is quite spectacular. Moreover, after the formation, there was no noise in the huge army except for the orders of the officers and the neighing of the horses' noses, which shows how strong this army was. In fact, these 30,000 cavalry have just been transferred from the battlefield of the Li State, and they have just experienced the baptism of war, and their combat effectiveness can be seen.

Zheng Xiu's 30,000 cavalry were all heavy armored cavalry, each cavalry was wearing strong black armor, and on their chests, a hideous and terrifying red wolf head was drawn, which was the symbol of Zheng Guo's wolf head army, and in the eyes of Zheng Guo's soldiers, this symbolized supreme honor.

Although the number of these 30,000 cavalry was 30,000, there were 90,000 horses, an average of three horses per man. To the north of Zheng was a vast steppe, rich in war horses with good endurance and speed, and to be able to form such a powerful cavalry force, only Zheng Guo could do it in the Central Plains.

Xia Yu was lying on the cliff, looking at the menacing 30,000 iron horsemen below, and his face couldn't help but show a look of envy. He licked his lips and grinned solemnly: "After today, these high-quality war horses will all belong to me." (To be continued......)
