In the open space in front of the city wall of Youxian County, six torsion thunderbolt cannons were safely erected under the protection of more than 7,000 troops of Pang Yan's commander.

A rain of rubble began to be thrown at the city wall, although these pieces of rubble were not enough to kill, but they also caused a moment of confusion on the city wall, and the heads would be broken and bleeding if they were hit on the head by the rubble.

This inevitably made the defenders on the city wall have a little less suppressive power on the cave houses and carts digging the city wall below, and they have no time to avoid the falling stones in the air.

At this time, urns filled with new granular black powder were transported to the front under the protection of the cave house cart.

Soon pots of black powder were placed in the dug cavern and then resealed with the excavated rammed earth, leaving only a fuse protected by a bamboo tube.

"......"

After the four fuses hidden in the bamboo tube were lit, they quickly extended into it with flickering sparks, and then divided into several separate lines and burned into the black powder jars.

At the same time, the cave houses and cars that were originally in front of the city wall also retreated quickly, which made Liu Pan's soldiers on the city wall a little confused for a while, obviously they didn't do anything, why did these people retreat.

Suddenly, an inexplicable panic appeared in their hearts.

"Boom...... Boom...... Whoa......"

Several violent explosions sounded, and a section of the city wall in Youxian County arched as if twisted, and then a large amount of loess and gravel poured outward as if there was a catharsis.

"It's gone!" "Thunder on a dry day! ”

With the ups and downs of the ground of the city wall, many people fell to the ground, and those Liu Pan soldiers who were just at the top of the blasting city wall were even more likely to fly directly into the air with the impact of the black flame explosion under the city wall, and fell to the ground bleeding again.

The blasted rammed earth wall collapsed into a hole, as if it had formed a notch, forming a slope on the outside, allowing the besieging side to rush directly along the slope to the wall, and then kill the wall.

Pang Yan, who had been prepared outside the city wall, suddenly took the lead and rushed to the city wall of Youxian County with more than 7,000 people behind him, "Kill!" Kill! Kill! ”

Pang Yan shouted three times in his mouth, waved his two-headed mace and rushed directly to the collapsed city wall, then jumped off the war horse, and then rushed to the slope of the city wall, and after a while, he was already standing on the top of the city wall.

Chen Qiang, who was behind Pang Yan, also held a long hammer in his hand and followed him closely, although his loyalty was not high, but now it was obviously the time of meritorious service, no matter what, it was impossible for him to work in such a situation.

Behind them were four thousand crossbowmen and three thousand sword and shield men, who followed quickly, and the crossbowmen had already begun to shoot crossbow arrows at the city wall, helping Pang Yan to force back Liu Pan's soldiers who rushed up.

In the follow-up military formation commanded by Wang Yuyan, the remaining more than 10,000 soldiers of the Xionglu battalion were also under the command of other general-level officers, and most of them formed a 2,000-person phalanx with four curved troops, and then rushed towards Youxian to kill.

This is the whole army attacking, ready to capture Youxian in one fell swoop.

"Kill! Kill! ”

For a while, Zhu Wei's soldiers rushed to the city wall of Youxian County like waves, and Pang Yan at the front had already led his troops to the side of the city gate tower, and Liu Pan's soldiers in Youxian County were almost powerless to resist.

The movement of the black gunpowder blowing up the city wall is really amazing, not to mention the ordinary soldiers in Liu Pan's army in Youxian County, even the main generals like Liu Pan are a little unable to react, and they are all a little shocked.

And now it was Pang Yan who took the lead in leading the troops to rush up, thinking of the powerful force shown by Pang Yan just now, no one dared to go up to resist, and the crossbow arrows covered by the four thousand crossbowmen behind him like rain also made Liu Pan's soldiers unable to gather troops to launch a counterattack.

Therefore, on the city wall, many of the soldiers led by the generals and marquis of Liu Pan were killed and scattered in all directions, and it was difficult to find their respective comrades, and no one could organize an effective counterattack.

Now that the city wall has been captured, Liu Pan can only return to the city, gather other soldiers who are on standby in the city, and reorganize people to resist the Zhu Wei army that entered the city.

Therefore, the city wall of Youxian County was soon covered with the figures of Zhu Wei's soldiers, and then the city gate drawbridge fell, and the city gate was also opened, and the gate of the entire Youxian County was opened to Zhu Wei's army.

The follow-up Zhu Wei soldiers rushed into Youxian County along the open city gate, as if a flood had poured into a reservoir, so that the county was broken.

At this time, located on the top of the hill military village five miles away from Youxian County, and the gate of the village was also opened, Huang Zhong rushed out with 5,000 soldiers and rushed directly to the main position of Zhu Wei's army.

Huang Zhong knew very well that Youxian could no longer hold it, and the only thing he could help Liu Pan was to defeat the main formation of Zhu Wei's army, and perhaps disrupt the command of Zhu Wei's army, so that Liu Pan in Youxian County would have a chance to counterattack, or withdraw from Youxian safely.

It's just that Wang Yuyan had prepared before, so that Mu Lan with 5,000 sword and shield men and 1,000 crossbowmen, plus more than a dozen spear and tiger carts like moving walls blocked between Huang Zhong's military camp and Youxian, so Huang Zhong can only continue to advance by breaking through this defense line, which is not an easy task.

Seeing Huang Zhong leading his troops to rush out of the hill military village, Mu Lan had already commanded five thousand sword and shield men to form a gossip-type tortoiseshell army formation here.

In this overall gossip-shaped military array, there is almost no Zhu Wei soldier at all, and a song of soldiers forms a round tortoiseshell shield array, that is, almost a song of Zhu Wei soldiers forms a military formation composed of large and small shields.

On the periphery of this tortoiseshell shield array is a circle of large shield soldiers, holding large shields like a wall to hide the hidden figures of soldiers inside, and inside the army array are sword and shield hands holding one-handed shields to cover their heads.

When viewed from the outside, it looks like giant turtles entrenched on the ground, and you can only see the shield hidden outside, but you can't see a single soldier hidden inside.

And these tortoiseshell shield arrays are combined, but they form a Bagua-type military array that covers an area of several miles.

Some of these tortoiseshell shield formations rely on the dozen or so spear and tiger chariots to form a wall barrier, pushing these spear and tiger chariots to move in the military formation, and they can use the wall barricade formed by the spear and tiger chariots to cover many areas of the military formation, so that outsiders cannot see through the changes of the entire military formation at a glance.

Between the barricades of these spear and tiger chariots and the tortoiseshell shield array of curved soldiers, there were some passages, about two or three people wide, which seemed to be for the enemy to walk.

It's just that from the sky, these passages look like labyrinthine passages in the entire military array, which makes people dazzled, and it is difficult to find the direction that leads directly to the command platform in the core area of the military array......
