The sniper starts from the bright sword escape period

Chapter 121 To hit a moving target, you need to calculate the lead time

When Jiang Ziya heard the painful roar of the devil-seeded mountain turtle, he flew to observe it, and then found that there was a very inconspicuous small bullet hole with a diameter of only one centimeter at the bottom of the six-meter-deep crater on the turtle shell.

And this bullet hole is the bullet hole pierced by Bai Lixiu's Xingyun carving knife on the armor-piercing warhead.

The indestructible characteristics make the hard shell of the devil-seeded mountain tortoise look like mud in front of it.

Therefore, although the diameter is 15 centimeters and the length is [-] meters, the shell-piercing shell that weighs ten tons is blocked by the shell of the devil-seeded mountain tortoise.

However, the star meteor carving knife in front continued to penetrate the shell of the devil-seeded mountain turtle.

It has penetrated the last four meters of the turtle shell, and then penetrated into the head of the devil-seeded mountain turtle hidden behind the shell.

It's just a pity that although it penetrated into the head, after all, the diameter of Bailixiu's carving knife is only one centimeter, and the length is only twenty centimeters.

Therefore, it is nothing in front of the head of the Demon Seed Mountain Turtle with a diameter of 50 meters.

This is like piercing a human brain with a diameter of [-] centimeters with a thin needle measuring only [-] centimeters.

Of course, the difference is that this thin needle is pierced at a speed of more than 1000 meters per second.

So the released kinetic energy is still destroying the brain tissue of the demon-seeded mountain turtle.

This is also the reason why the devil-seeded mountain tortoise roars in pain.

The severe pain in the brain made the devil-seeded mountain turtle a little crazy, and it directly stretched out its head and roared angrily in the direction of the border city.

But Jiang Ziya, who was flying above the head of the devil's mountain tortoise, discovered that there was actually a white liquid ejected from the head of the devil's mountain tortoise.

That's right, this is the brains of the demon-seeded mountain tortoise that had been shaken into a paste. Under the action of intracranial pressure, the passively shaken brains spewed out like a fountain.

I have to admire the tenacious vitality of the devil-seeded mountain tortoise. Its brains have been sprayed like a fountain, but its body is still tenaciously crawling towards the border city.

Seeing this situation, Bailixiu naturally didn't hesitate to give this devil-seeded mountain turtle another one.

Therefore, I immediately used the second feature of the Xingyun carving knife, never falling, that is, every 24 hours, I can re-summon the Xingyun carving knife that is no longer by my side to my hand.

So as soon as Bai Lixiu stretched out his hand, with a thought, the Xingyun carving knife appeared in Bai Lixiu's hand out of thin air.

Bai Lixiu looked at the Xingyun carving knife for a while, and found that it was indeed indestructible. After experiencing a high-speed impact of 2000 meters per second, the blade of the Xingyun carving knife was still intact without leaving any marks on it.

Without too much hesitation, Bai Lixiu drilled a hole in the head of the tungsten alloy core of another armor-piercing bullet and inserted the star meteor carving knife into it as the tip of the armor-piercing bullet.

Then the city defense troops controlled the crane to hoist the cannonball up and send it to the cannon hall of the Demon Killing Cannon.

During the time when the demon-killing cannon was reloading, Zhong Wuyan saw the devil-seeded mountain turtle struggling violently and trying to break free from the deceleration spell, especially after seeing the white brain fountain on its head. Give it an injury plus.

So he jumped on the back of the devil-seeded mountain turtle, and then jumped up high again, hitting the wound that was spraying brains.

With this smashing, the brains that were still sprayed like paste flowed back into the brain of the devil-seeded mountain tortoise, and immediately made the devil-seeded mountain tortoise, which had become more comfortable because of the spraying of brains, become more irritable up.

The limbs of the devil-seeded mountain tortoise frantically pulled the ground, but such frantic struggle became the last straw that crushed Jiang Ziya.

Jiang Ziya, who was already running out of mana, couldn't hold on any longer, and cut off the continuous mana output of the slowing spell as soon as his body softened.

Without the control of the deceleration spell, the devil-seeded mountain tortoise was like a wild horse that had broken free from the rein, and its speed was immediately raised to the extreme and rushed towards the border city.

Such a situation made the city lords on the border wall and the city defenders look stupid, because the moving devil-seeded mountain tortoise is not easy to shoot!
And it's still a demon-seeded mountain turtle running at a speed of 72 kilometers per hour.

Of course, what makes people even more desperate is that at this time, the third shell of the Demon Killing Cannon has not yet been loaded.

How long will it take to install it, the commander of the city defense army asked the command captain who was supporting the loading shells in a hurry.

20 seconds, it only takes 20 seconds to complete the state, and now the bolt is tightened.

Naturally, it is impossible to tighten the gun bolt weighing dozens of tons by humans. Naturally, the motor is used to drive the multi-stage reduction gear, and then the reduction gear is used to increase the torque, and finally the gun bolt is screwed in place before firing.

If the gun bolt is not tightened, it will definitely not be able to withstand the super high pressure during firing. The final result is that the gun bolt is not fired, but the gun bolt is blown up, and finally the gun is destroyed.

When Bailixiu heard that it would take 20 seconds to tighten the bolt, she silently calculated how many seconds it would take to hit the border city wall at 2000 meters at the current speed of the devil-seeded mountain tortoise.

One hundred seconds, it takes one hundred seconds for the monster tortoise to hit the city wall at a speed of 72 kilometers per hour, so Bailixiu began to mobilize the muzzle and point the muzzle at the 1000 meter point on the way of the monster tortoise.

Then it began to wait for the devil-seeded mountain turtle to enter the point where its muzzle was aiming.

Of course, when shooting a moving target, it is necessary to calculate the amount of advance to hit the target.

For example, now that Bailixiu wants to shoot the devil-grown mountain tortoise moving at a speed of 72 kilometers, then he can't aim the crosshair at the devil-grown mountain tortoise.

Because in this way, the position he hit is indeed not the position he hit.

The point 1000 meters ahead of the mountain turtle that Bailixiu was aiming at was two kilometers away from the demon-killing cannon where Bailixiu was located, because the demon-killing cannon was installed on a high tower in the center of the border city, and the high The tower is one kilometer away from the city wall, so not counting the 300-meter height of the tower, it takes about one second for the shells of the Demon Slayer Cannon to fly two kilometers per second at 2000 meters.

But one second is already enough to make the devil-seeded mountain turtle advance 72 meters at a speed of 20 kilometers per hour.

So if Bailixiu didn't calculate the advance amount, and aimed directly at the center of the head of the devil's tortoise, the actual hit position would be the neck of the devil's tortoise.

There is no way to cause fatal damage to the devil-seeded mountain tortoise in such a position.

After 20 seconds, the bolt of the Demon Killing Cannon was screwed in place, and the Demon Killing Cannon could be fired safely.

However, Bailixiu didn't move the demon-killing cannon anymore, but continued to wait for the devil-seeded mountain tortoise to enter the shooting point that Bailixiu had set in advance.

At 29 seconds, Bai Lixiu pressed the firing button of the Demon Killing Cannon.

boom!
The Demon Killing Cannon let out a terrifying roar again!

An armor-piercing projectile weighing ten tons, 15 meters long, and 2000 centimeters in diameter flew out from the muzzle of the Demon Slaughter Cannon at a speed of [-] meters per second.

By the time the armor-piercing projectile flew a distance of 2000 meters in one second, the magic-seeded mountain tortoise had just finished the last 20 meters.

So the third armor-piercing projectile fired by the Demon Killing Cannon finally hit the center of the devil-seeded mountain turtle's head without the barrier of the turtle shell.
