Chapter 119 The King's World Has No Uranium
Moreover, the shrinking head of the devil-seeded mountain tortoise is different from that of ordinary tortoises. Although ordinary turtles retract their heads, they can still see their heads retracted inside. That is to say, they can still be seen if they are shot with a gun. hit it directly on the head.

However, after the monster tortoise retracted its head into the shell, a piece of carapace fell from the inside to completely block the hole left by the retracted head.

Now even if you want to hit its head, you have to pierce the carapace first to hit its turtle shell.

Seeing this situation, Bai Lixiu couldn't help but look away from the sight of the cannon and looked at the commander of the city defense army who was also observing with a telescope and asked:
"What should I do now and continue to shoot?"

Regarding Bailixiu's question, the commander of the city defense army nodded helplessly and said:
"Let's fire! Demonic monsters at the level of demons are all crisis-sensitive, and will dodge or defend as long as they encounter a life crisis!"

After Bailixiu heard the words of the commander of the city defense army, he pressed the biggest firing button on the right hand side without hesitation.

As the button was pressed, Bai Lixiu hurriedly shook his body sitting on the gun barrel backwards. If Bai Lixiu hadn't tied the seat belt, he might have to take Bai Lixiu from the chair. down.

Then followed by a deafening roar.

As for how loud the sound was, Bai Lixiu couldn't tell, because at this time, the glass of the house in the direction pointed by the muzzle of the Demon Killing Cannon had been completely shaken by the muzzle storm, or the muzzle shock wave. Broken.

Even if the giant demon-killing cannon was fired from a tower more than 300 meters high, it still shattered the glass of the house near the cannon's mouth.

But fortunately, after the discovery of the devil-seeded mountain tortoise, the city lord has ordered the residents of the city to enter the underground shelter and take refuge, so they are not afraid that the muzzle shock wave will hurt innocent people.

The distance of four kilometers is only two seconds of flight time for a tail-stabilized sabot-piercing projectile with a muzzle velocity of 2000 meters per second.

Due to the slender body and the high-density materials used in the tail-stabilized sabot projectile, the air resistance it encounters when flying in the air is very small, and naturally the deceleration per [-] meters is not as high as that of ordinary bullets. Slow down by tens of meters.

After flying 4000 meters, the tail-stabilized shell-piercing projectile fired by the Demon Killing Cannon still had a speed of more than 900 meters per second, so its kinetic energy did not lose much.

But what Bai Lixiu didn't expect was that the huge kinetic energy hit the carapace blocking the entrance of the devil's mountain tortoise, and instead of hitting it, it went through and only left a deep pit about five meters deep on it. .

The super shell-piercing armor-piercing projectile that can penetrate 15 meters of homogeneous steel plate actually only produced a deep pit with a depth of three meters.

From this point of view alone, the shell strength of this devil-seeded mountain tortoise is far superior to that of ordinary steel plates.

Of course, in addition to the strength of the tortoise shell, there is also the thickness of the tortoise shell. It was five meters deep, but it still did not penetrate the tortoise shell.

The thickness of this tortoise shell has far exceeded the armor of any battleship that Bailixiu knows.

After all, the turret shield armor of the largest and most powerful battleship Yamato is only 650mm.

But the shell of this demon-seeded mountain tortoise was pierced three meters deep, but it still hasn't been penetrated.

After this shot, not only Jiang Ziya, who was maintaining a slow spell in mid-air, was stunned.

Zhong Wuyan, who was running far away, turned around and came back to see this scene and asked in a daze:
"Old man Jiang, I didn't expect you to have a trump card in this border city! It's just that your trump card doesn't seem to be very effective!"

Zhong Wuyan said sourly. After all, in terms of power and effect alone, the power of this cannon is far greater than that of Zhong Wuyan's previous hammering technique that fell from the sky.

However, Jiang Ziya was not in the mood to pay attention to Zhong Wuyan's ridicule, but flew to the demon-seeded mountain turtle that was kicked out of the mountain pit, touched the traces on it and said:

"It doesn't make sense! I have used such a demon-killing giant cannon to pierce through a demon-seeded mountain tortoise the same size as this one before! Why can't it work now!"

While talking, Jiang Ziya touched the deep pit that was punched out, but when Jiang Ziya noticed the traces around the deep pit, he found something was wrong.

Because the shell of this devil-seeded mountain tortoise is not made of iron.

That's right, the shell of the demon mountain tortoise is not a calcium metal shell like that of ordinary tortoises.

It is usually made of iron tortoise shells, because the devil-seeded mountain turtles usually look for iron ore veins, and then eat special ore veins, absorbing the iron in the iron ore to strengthen their turtle shells.

As the iron ore is absorbed more, the entire turtle shell will naturally become iron.

Following Jiang Ziya's careful observation, he discovered that the shell of the demon-seeded mountain tortoise was actually made of the same material as the tail-stabilized shell-piercing shell fired by the demon-killing cannon, both of which were tungsten alloys containing a large amount of tungsten metal.

Then naturally there is only one possibility, and that is that this devil-seeded mountain turtle found a tungsten mine, and also ate a large amount of tungsten metal mine, so it formed such a tungsten alloy turtle shell with amazing defense.

So when the armor-piercing material is the same as the material used to make the armor-piercing projectile, the material advantage of the armor-piercing projectile will naturally disappear.

Therefore, the armor-piercing effect will naturally be greatly reduced.

The way to solve this situation is naturally to replace better armor-piercing projectile materials to make armor-piercing projectiles.

For example, uranium metal is a very good armor-piercing material.

The armor-piercing ability of the fin-stabilized sabot-piercing projectile made of depleted uranium alloy is generally more than [-] times that of the tungsten alloy armor-piercing projectile.

Because the depleted uranium armor-piercing projectile has armor-piercing self-sharpening and high-temperature combustion properties that tungsten alloy armor-piercing projectiles do not have, it can also generate a high temperature of more than [-] degrees during impact to increase the power of armor-piercing.

However, what disappoints the players of Super Play Space is that although they have already learned how to make nuclear bombs in various mission worlds, but unfortunately, there is no uranium on the Continent of Kings, or the players have no uranium in the Continent of Kings. Find uranium.

So don't talk about using depleted uranium armor-piercing bombs, even nuclear bombs cannot be manufactured.

After all, with the power of nuclear bombs, no matter how powerful the defensive power is, if a nuclear bomb goes down, it will still have to die.

But what the players didn't expect was that there was no such metal as uranium on the King's Continent, so let's not mention uranium or plutonium produced by uranium fission.

"It's over! It's over! It seems that this border city is really going to be destroyed today."

After the commander of the city defense army saw that their killer mace, the demon-killing cannon, had no effect, he immediately said with a serious face.

But Bai Lixiu did not give up, because he thought of a way to increase the performance of armor-piercing bullets.

In the meantime, Bailixiu took out the star meteor carving knife that he had used to open the treasure box before, and then squatted on the pointed part of an armor-piercing bullet and began to fiddle with it.
