Chapter 288: Shelling

The total number of giant guns on the two battle stars is about 45,000. If each gun can successfully kill a battleship, then the 45,000 are enough to bomb all the warships of the pursuer civilization. Once again, hit the air twice.
It's just shooting, it's not that simple.
When a shell is fired, it will first be affected by the gravity of the brown star and the light green star. To change the trajectory, it must be calculated in advance. Subsequently, the shells will be affected by the gravitational force of the star, and the trajectory will change again.
Further out, the fifth gaseous planet, sixth gaseous planet, seventh...
The gravitational force of each planet will affect the trajectory of the shell more or less, perhaps very slightly, and can be a thousand miles away.
In addition, it is necessary to calculate whether the same batch of shells will collide, adjust the firing order, predict the enemy's position, etc.
This feeling is actually very similar to sniper on the planet. When the target is far enough, objective factors such as gravity, wind speed, and magnetic field will affect the bullet.
In addition to calculating the trajectory, the projectiles that are fired may be intercepted by the other party. After all, the flight speed of the energy projectile reaches only about half the speed of light. It is so far away from the star system. Western Zhejiang time is enough for the other party’s interception system to do. In response, take some countermeasures.
"Zu Zhu, the enemy entered the range." Xie Sang preached.
"Open the gun!" Xie Yan issued a shelling order, and by this time, he was no longer hiding.
Xie Sang turned off useless programs, concentrated all the computing units on these 45,000 guns, and started extremely complex operations.
The first bombardment also had a tentative taste in it, and in order to ensure the hit rate, it was not intercepted by all the enemies, so they decided that every hundred giant guns aimed at a target!
After a few minutes, four hundred and fifty targets were locked.
Boom~
45,000 giant cannons fired, and the sound of the cannons popped through the world. Brown stars, light green stars, brown satellites, and green satellites resembled four black chrysanthemums of different sizes.
After the shells were fired, Xie Sang started the reloading process, checked the damage of the giant guns, and reloaded.
"The report, in the first round of launch, 45,000 giant guns actually responded to 44,921..."
"Refilling..."
"Checking the cause of the misfire of the seventy-nine giant guns..."
Xie Sang broadcasts the launch situation in real time...
"Preliminary inspection showed that the shells of the sixty-three cannons were damaged, and the robot was being commanded to unload and reload.
"Checking the damage of sixteen giant cannons..."
"Forty-four thousand nine hundred and twenty-one doors are refilled, and the goal is locked..."
"Sixty-three giant cannons have been reloaded and the target is locked..."
"Sixteen cannons damaged four, and the remaining twelve were reloaded..."
"Fill in! Three, two, one... launch!"
The second celestial artillery sounded, and at this time, the first round of shells had just left the seventh gaseous planet in the star system.
Xie Sang continued to start the third round of inspection and loading, and counted the number of dumb guns in the second round to screen out the huge guns that were completely damaged and could not be used again.
After the third shot, the shells fired in the first round finally approached the target.
Among them, more than 10,000 dead star psionic shells were directly invalidated, and the reason was no other. The prediction failed, and it was empty. At this speed and distance, let alone the positioning system, even self-aided hanging is powerless.
And these empty shells will continue to fly in space at this speed in the future, looking for which unlucky guy to hit...
The remaining more than 30,000 have successfully positioned themselves as their masters.
On this side, the pursuer civilization fleet began to attack these dead star psionic shells and intercepted them.
The aftermath of the explosion caused by the interception will also reduce the power of nearby dead star psionic shells and slightly change their trajectory, and a group of dead star psionic shells will die or be forced to stay away from the predetermined route.
Hardships...
In the end, there were only fourteen thousand nine hundred and twenty-one Death Star psionic shells, and there were only more than 9,000 pieces left. The front was unobstructed, and they all hit the suffering master.
"It is reported that the statistics of the first round of artillery strikes against the enemy, a total of 281 warships were hit and scrapped directly, with a hit rate of about 62.4%." Xisang continued to report.
"Adjust the target quantity." Xie Yan said.
The hit rate is 62%, which can be understood as 62 shots per 100 shots, so most of the Death Star psionic shells are whip corpses.
Therefore, starting from the fourth round of bombardment, Xie Sang chose forty-five cannons to aim at a target and locked one thousand warships at a time.
As for why not ten giant guns aimed at one target and attacked 4,500 warships at the same time... Because of the computing power of Xie Sang, it was not possible to efficiently complete this level of calculation, which would only extend the interval of bombardment, but not cost-effective.
"It is reported that the statistics of the second round of artillery strikes against the enemy, a total of 232 warships were hit and scrapped directly, with a hit rate of about 51.6%."
"Report, the third round... the hit rate is about 59.7%"
"Report, the fourth round... A total of 544 warships were hit, 540 were scrapped, three were slightly injured, and one was intact, with a hit rate of about 54.4%."
In the fourth round of shelling, four warships survived!
Among them are the problems of reduced firepower concentration, such as the three lightly wounded warships, and the problem of kicking to the iron plate. In other words, that intact battleship is the main battleship of the pursuit of civilization!
Xie Yan asked Xie Sang to mark this battleship, and then continued to attack.
The next fifth round, sixth round, seventh round...
Each round has about 400 to 600 enemy warships falling, and the number is getting less and more as it gets behind, because the ones that can be hit are often more ordinary warships. After these warships are eliminated, the enemy warships’ The overall quality is slowly rising.
In addition, the enemy also began to use the planets to cover and reduce losses.
During the eleventh round of shelling, of the 423 targets hit, only 37 were scrapped!
Xie Yan stared in that direction.
Not surprisingly, the 1,500 ships nearby are the main fleet of the other party!
"Zu Zhu, do you want..." Xie Sang means hitting and bombarding this batch of warships, and dampening the main force of the enemy.
"No, go ahead, destroy all ordinary warships first!" Xie Yan did not agree. You know, his plan is to kill the enemy's living power and reduce the total number of enemy warships, not to wipe out the enemy forces.
Even if the latter thought, it would be difficult to achieve with these more than 40,000 Death Star Psionic Cannons!
"However, if they do not continue to bombard and block them, they will soon come over!" Xie Sang Chuanian said.
Xie Yan responded: "I know, I just want them to come over."
