Chapter 645 Giant Turtle Shell Shield

"Boom boom boom boom boom!"

The roaring sound of artillery appeared instantly, but the more than 20,000 artillery pieces did not fire at the same time, but in stages at different positions. The firing time of different batches of artillery was five seconds apart, and the total was divided into five batches. The purpose of this was to Prevent huge resonance and knock down the city wall.

Although the walls of Qinghu Fortress are strong, the resonance generated by tens of thousands of artillery fire at the same time may still knock the walls down. Even if there is only a slight possibility, precautions must be taken in advance.

Li Mu's eyes were so full of energy that the speed of the cannonballs suddenly slowed down in his eyes. Then he saw dense cannonballs whizzing towards the sky. The artillery was so dense that it was like heavy rain falling.

The first batch of artillery fires, the second batch of artillery fires, the third batch of artillery fires, the fourth batch of artillery fires, the fifth batch of artillery fires, and then the cycle starts over and over again, until the fifth batch of artillery fires, it is vague. The shock of about 1000 meters began to appear. This was the first round of shells fired by nearly 5,000 heavy artillery pieces.

On the big screen in the command center, everyone watched the fires rising into the sky from the water monster army. Most of the heavy artillery in Qinghu Fortress were 155mm self-propelled howitzers. The full lethality diameter of this artillery was more than 60 meters. The maximum power can cover a basketball court.

A falling artillery shell can create a crater with a diameter of ten meters on the ground. The fragments produced by the artillery shell can kill all unprotected living forces within an entire football field. Every falling heavy artillery shell is the god of death waving the sickle in his hand.

But this is only for humans. For monsters, the biggest threat that cannonballs can pose is a direct hit and explosion. The fragments it generates are almost impossible to kill other monsters. At most, they can only suffer a little. Injury, in front of the demon clan, the power of human technological weapons plummeted.

Although the power of the heavy artillery plummeted, the victory was due to the large enough number. Nearly 5,000 cannonballs fell in each round. The densely packed cannonballs continued to fall, one after another, seemingly endless.

The entire city wall is constantly trembling. Even if the city wall is extremely strong for humans, it still needs constant trembling to offset the impact of heavy artillery fire.

"Mastermind, investigate the water demon!"

Li Mu glanced into the distance. Nangong Mingyue raised her hands and covered her ears with a panic expression. The water demon army hadn't appeared yet, but she was already shocked by the terrifying fire defense of Qinghu Fortress.

Li Mu took advantage of everyone being attracted by the terrifying sound of cannons and quietly released a silver ball the size of a thumb. The ball flew out of the city wall and then sank quickly, flying towards the water demon army.

Li Mu stood on the edge of the city wall and looked down. He saw blazing flames erupting from the dense shooting ports, and the dense shells flashed away.

The shooting port on the wall of Qinghu Fortress is very narrow, only one and a half meters wide in the horizontal direction, but more than five meters high in the upper and lower directions. Three meters down, and the depth of the shooting port is a full dozen meters.

This design can prevent monsters from getting in to the greatest extent, unless they are small water monsters with a body width less than one meter, but such water monsters can easily be destroyed instantly when they crawl into the shooting port.

"Appeared!"

Soon, the silver ball flew above the water monster army. The height of the silver ball was extremely high, even higher than the upper limit of the flight of the unmanned reconnaissance aircraft, but the picture it sent back was far higher than that of the unmanned reconnaissance aircraft. The pictures taken by the reconnaissance plane should be clear.

A picture appeared in Li Mu's mind. He saw dense shells falling continuously, harvesting the life of the water demon army in sheets. Even if many of the artillery fires failed to hit directly, basically one or two thousand water demons could be directly eliminated in one round. The firepower of the artillery fire was full-coverage, and whether they were ordinary water monsters or elite monster soldiers controlled by the Four Hegemons of Qinghu, they were all being eliminated.

As long as it is hit by a heavy artillery shell, even an elite demon soldier will be seriously injured if it survives. The dense heavy artillery shells fall, and water demons continue to fall in pieces. The biggest advantage of the artillery shells over rocket launchers is that they are densely packed and seemingly endless.

Li Mu even saw several heavy artillery shells land directly on Ao Guang's dragon.

"Huh, despicable human being!" Ao Guang just raised his head and glanced into the sky. The flying shells froze and exploded in the air. Then Ao Guang casually raised the scaly dragon claw.

"Woo!"

The Yasha next to it took a long breath and blew the huge horn. When the horn sounded, the giant turtles in the water demon army suddenly stopped, their whole bodies shook heavily, and then the turtle shells on their bodies flew up piece by piece. , these tortoise shells flew into the air, and then quickly rotated one by one, supporting huge shields in the sky.

The size of each of these giant tortoises exceeds 20 to 30 feet. When their tortoise shells are unfolded, they can even form a giant shield with a diameter of nearly 200 meters. The shields are formed in a blink of an eye, and the sky soon appears. Thousands of giant shields like this.

"Boom boom boom boom boom!"

Thousands of huge shields appeared in mid-air, covering the sky and the sun. The heavy artillery shells were directly blocked by these shields. The shells hit the tortoise shell. The demonic energy on the tortoise shell dimmed slightly, but then they were unscathed. A large number of shells were hit by the tortoise shell. Blocked by the shield, it was impossible to hit the water demon's head again.

As soon as these tortoise shell shields appeared, at least more than half of the cannonballs were directly blocked, and the casualty rate of the water demon army suddenly dropped rapidly.

One round of artillery fire dropped from being able to kill thousands of water monsters to being able to kill less than five hundred water monsters. The efficiency of artillery coverage against water monsters plummeted.

"The Qinghu Water Monster is also fully prepared for this war!" Li Mu looked at this scene. He was not unfamiliar with similar scenes. When humans and monster countries went to war, situations similar to group army battles often appeared. That was a real war. There are sneak attacks, there are strategies, there are plots, there are plots, and they are all used for victory. This is true for humans, and so is the demon race.

"Fill the armor-piercing bullets, load the armor-piercing bullets immediately!" Li Mu looked solemn, and without hesitation, he grabbed the walkie-talkie and ordered to the artillery troops in his defense area.

Li Mu ordered and rushed directly into the city wall. Nangong Mingyue saw Li Mu getting into the city wall, and she quickly followed.

"Coward, Mingyue is so blind that he has fallen in love with this kind of trash!" Zhao Xin's eyes flashed coldly when he saw this scene, full of cold murderous intent. He thought Li Mu was frightened by the scene of thousands of cannons firing. He was so frightened that he hid in the city wall.

"Quick, change to armor-piercing bullets, change to armor-piercing bullets immediately!"

Li Mu rushed into the city wall and directly shouted orders to the artillery commander in this section of the city wall.

"Armor-piercing bullets? Why change to armor-piercing bullets? After changing to armor-piercing bullets, if you can't directly hit the vital part of the water monster's head, you won't be able to kill the water monster at all!"

The artillery commander said with a puzzled look.

After the great changes in the world, due to the changes in the war environment, some military scientists developed a new type of artillery shell. This shell is more narrow and long. It contains a tungsten alloy armor-piercing warhead. It is specially used to deal with monsters with strong demonic aura and thick carapace. Monster.

However, the shortcomings of this armor-piercing bullet are also obvious. If it cannot directly hit the monster's head, even if it directly hits the torso, even if it penetrates the monster's torso, it will be difficult to kill or severely damage the monster. In terms of lethality, this armor-piercing bullet has The killing capability of a single target is far inferior to that of a high-explosive warhead.

After all, the vitality of monsters far exceeds that of humans. If a human's body and trunk is penetrated, the possibility of death is very high, but monsters are different. Even if they are hit in the torso, they can survive for a period of time. If they miss the vitals, it is even more insignificant. .

"The water demon has set up a defense. We need to use armor-piercing bullets to break the defense. Hurry!" Li Mu roared with a serious look on his face. "I am the supreme commander here. Follow my orders, soldiers!"

Time is too important now. Every minute and every second cannot be wasted, because artillery has a range. It has both a maximum range and a minimum range. Once the water monster army comes under the city wall, the threat of the artillery force will drop sharply. .

It is necessary to bring out the maximum lethality of the artillery unit without wasting any time.

"Yes, sir!" The artillery commander hesitated. The soldier's nature took over. Since there was an order from above for Li Mu to be the temporary commander-in-chief of this section of the city wall defense area, he had to obey the order.

"Quick, everyone change into armor-piercing ammunition, quick, quick, quick!"

With an order, all the artillery units defending this kilometer of city wall immediately took action. The artillerymen quickly opened a special large wooden box. Inside the wooden box were all a kind of slender artillery shells, which were one-third thinner than ordinary artillery shells. One, but almost twice as long.

However, the number of armor-piercing shells is very small. Each heavy artillery is equipped with only ten armor-piercing shells, and the number is only one-fifth of the high-explosive shells.

"Fire!"

All two thousand heavy artillery pieces were equipped with armor-piercing bullets. Li Mu waved his hand and roared, and two thousand armor-piercing bullets roared out.

At the same time, in the command post at the center of Qinghu Fortress, Nanye looked at the huge tortoise shell shields propped up in the picture, his expression extremely ugly. General Nanye had fought many times with the Qinghu water demon, and had experienced many battles, big and small. But this was the first time he saw General Nanno with a giant tortoise-shell shield like today.

It was the first time for him to see it, and it was also the first time for other officers in the command center to see it. When they saw the heavy artillery shells being intercepted, everyone felt that it was extremely difficult and a little helpless.

"The killing efficiency of the artillery unit has been reduced by half. Sir, what should we do?"

An officer said nervously that if the water demons could not be killed before they came forward, the pressure on Qinghu Fortress would be great when the water demon army came under Qinghu Fortress.

"Continue to focus the fire and destroy those tortoise shell shields as quickly as possible!" Nanye said solemnly.

"Sir, look!"

At this moment, a staff officer suddenly exclaimed.
