Early the next morning.

As soon as he got up, he heard the sound of drums echoing.

The soldiers hurried to report, and Budugen came to attack the city again.

He immediately ran to the city tower, only to see countless Xianbei people, raising iron shields one by one, and approaching the city tower of the pass.

"Machine gun preparation, artillery bombardment!"

Arrangements were made quickly.

Xianbei people's iron shields, this is not the first time to use, the purpose is to resist the bullets from the Yanmen Pass, there is a certain effect, the penetration of machine guns and rifles is not very strong, the iron shield is quite thick, and the bullets still can't penetrate at present.

In the previous Xianbei attack, they used this shield to approach to the bottom of the city tower, and then climb through the ladder, but as long as they left the protective range of the shield, they would be killed by bullets.

You can't climb the ladder at all.

So, Sima Yi changed his plan and used the shield to consume the ammunition he was pulling, but what he didn't know was that Ma Jun was mining in Bingzhou, and one of the arsenals was on the edge of the mine in Bingzhou.

The trick began when Budugen went south for the first time, and he went to Bingzhou and Youzhou for help.

The arsenal first sent a huge amount of ammunition, and Guo Yi also sent 10,000 people to Yanmen to help lead the defense, and in Tianchou, Youzhou, he also sent 20,000 people to support Yanmen Pass.

At this time, there were more than 50,000 people at the pass.

During this period, Budugen increased his troops, recruited a large number of troops from various tribes in Xianbei, and put all of them into the front line.

In the face of the attack of the Xianbei army of Budugen, 50,000 people were enough to defend.

It's just that there are also some firearms in the Budugen army.

For example, artillery would bombard the walls of their passes to cover the approach of the infantry.

Rumble!

Listening to the order, the defenders on the city tower fired their cannons first, and bombarded the advancing Xianbei army with one cannon, and immediately defeated many shields.

Then the mortar shell crossed a parabola and fell into the Xianbei army and exploded.

Shields can block bullets, but not shells.

The mortar shells easily harvested a large number of heads, and the Xianbei soldiers who advanced over suffered a lot of casualties, and there were not enough left, and they continued to advance, and they were not afraid of death.

"Go on!"

Pull shouted.

The gunners fired continuously, bombarding the enemy.

At this time, the artillery in the Xianbei army finally sorted, and the shells of those artillery, although they were all iron bullets, had been improved by the traverser in Taiping Dao, and the range was longer than before.

The improved technology, Sima Yi also got it, and at this time he shouted: "Open the cannon!" ”

Rumble!

Outside the pass, there was also a burst of cannonballs.

The iron bullets slammed down on their walls, sending out a shock.

"Get down and get out of the way!"

Before they could be relieved, the second row of shells bombarded again.

But this time the angle of the bombardment was higher, and it could hit the battlements of the city wall of the pass, splashing the sky with rubble, splashing everywhere, and many soldiers guarding the pass were hit by the rubble, seriously injured, and dragged down by the soldiers behind for treatment.

With the cover of artillery, the Xianbei infantry, the pressure plummeted.

They raised their iron shields and marched faster, approaching the bottom of the city wall, but they did not dare to directly build a ladder to attack, the main thing was still to consume the ammunition of the move, use the shield to resist the bullets, and then look for an opportunity to attack.

"Mortars, artillery to suppress the Xianbei people!"

It is not very clear where the artillery of the Xianbei people came from, but their own artillery is more powerful, has a larger strike range, and is more advanced.

Mortar gunners are professionally trained and familiar with the characteristics of mortars.

They immediately dragged the barrels and shells back, avoiding the splash of rubble, and then gave a thumbs up to judge how far the Xianbei artillery was from the wall of the pass, and then adjusted the angle and lowered the shells.

A cannon bombarded out.

The Xianbei artillery below was about to fire again, but it was hit by a shell falling from the sky and exploded on the spot, and the Xianbei people who controlled the artillery were blown up so that their bodies were not even complete.

"Go on!"

The officer in charge of directing and operating the mortar shouted loudly at this time.

The gunners understood, and they didn't care about anything else, but just bombarded the enemy's artillery.

Other gunners were also firing their guns against the shield-carrying infantry.

Already part of the infantry, approaching under the city walls.

"Shoot!"

Pick up a rifle and pull the bolt to shoot down.

The other rifles and machine guns, the bullets shot down at the same time, hitting the shield with a peculiar sound.

Without the interference of the enemy's artillery, the gunners on the passes, without fear, shot and fired.

However, the Xianbei people below also have some muskets.

Their guns were troublesome, and after one shot, it took time to reload before they could fire a second shot, and these gunmen hid behind their shields and fired cold shots above the towers.

There were also some gunmen on the city tower, who were hit by these Xianbei gunmen and fell.

The Xianbei gunmen under the city were also killed one after another, but they continued to shoot and counterattack, and the two sides fought back and forth, and the bullets continued to splash, crisscrossing the city and the city.

"Drop the explosives pack!"

The trick was arranged in an orderly manner: "There are also wood and stones, all of them are smashed!" ”

Rumble!

The explosive pack is dropped, and an explosion appears above the shield.

Despite the iron shield defense, it still blew over part of the shield, shocking the Xianbei soldiers behind the shield, and then wood and stones fell down, knocking them to the ground.

The shield was knocked off, and the Xianbei soldiers could only wait to be harvested by bullets.

Sima Yi saw the mortars, and suppressed their artillery, several of which were scrapped, felt distressed, and saw that the momentum of the attack was weakening, and said: "Shan Yu, you can retreat." ”

"There is so much ammunition in Yang Zhao's army?"

Budugen had no choice but to order a retreat.

Sima Yi frowned and said, "We have consumed it for so long, we can't finish it, it's really a bit difficult to fight, it's just ......"

He looked south.

On both sides of Yanmen Pass, there are walls of the Great Wall and steep mountain ranges.

"If you can climb over the city wall and raid Yanmen Pass from both sides of the city wall, you may have unexpected effects, and you may be able to take the pass before Yang Zhao goes north."

Sima Yi said, and said in embarrassment: "But the terrain is steep, so it's not easy to do." ”

Bu Dugen thought for a long time: "Sanji, you immediately select five thousand good climbers in our army, I want to see how difficult the Great Wall and mountains are to climb." ”

Seeing that he had adopted his own idea, Sima Yi flattered: "Shan Yu, I have something that can assist in climbing!" ”

That thing, which he also brought out from Taiping Road, still remembered Zhang Ning and them, called it the Flying Tiger Claw, which could be used to assist in climbing, and could firmly grasp the rock wall and the edge of the wall, and Zhang Ning used it to attack the city wall of Westerners at that time.

The guy named Sanchi, go and arrange it right away.

Budugen is going to climb again this evening, and attack Yanmen Pass for the second time today.
