The ultimate star-destroying cannon renovation project is on the tenth day.

The charging of Andromeda α1024 star ring is completed.

24 star rings of star destroyers fired at the same time, and thick gamma light beams shone out, lying in the dark deep space of the universe, dazzling and magnificent.

The ultimate star destroyer renovation project has not been completed yet, but the counterattack from the α1024 star ring of Andromeda has begun.

"Star Ring launches a star-destroying weapon and is expected to arrive in 8 hours and 20 minutes." The intelligence is quickly transmitted among the three major fleets of the Carbon-based Alliance.

The Human Expeditionary Fleet held an emergency meeting to discuss response plans with the Mechanical Empire and Photosynthesis civilization.

Zhao Anya took the lead in doing intelligence summary and simple analysis: "An Andromeda α1024 star ring has 24 satellite destroyers launched.

"From the trajectory of the gamma rays, among the 24 satellite destroyers, 20 of them are the 12th planet, and the other 4 are our ultimate satellite destroyers.

"Based on the energy level reconnaissance results and substituting the planetary data model, it can be determined that as long as three planet destroyers hit the 12th planet, the planet will be destroyed within 3 hours and shattered into how fast the planet fragments will be.

"If the number of hit Star Destroyers reaches 10 guns, then the 12th planet will be destroyed in half an hour.

"In addition, the four Star Destroyer weapons that attack the ultimate Star Destroyer cannon, as long as any shot hits or a light cannon passes through it, is enough to destroy the ultimate Star Destroyer."

After reading the data summarized by the intelligence, everyone could see that the situation is very serious now.

"The Palse civilization's satellite destroyer weapon needs to be launched for 8 hours before it can hit the target. We can move the ultimate satellite destroyer within 8 hours and avoid shelling. This is not difficult." A senior executive of the Photosynthetic Civilization Fleet proposed the idea.

The ultimate star destroyer is equivalent to a star destroyer, and it is indeed very huge for a weapon.

However, in terms of the mesoscale of the universe, it is actually just a cosmic dust.

At a distance of light and second, it is actually possible for higher civilizations to shell a target that hits such a volume.

It is not difficult for higher civilizations to cross light and seconds to strike targets.

It can be said that higher civilizations have the ability to destroy any asteroid or meteorite in the star system through shelling.

However, this has a prerequisite.

That is, the shelling target must be a fixed target.

A fixed target does not refer to a target that is completely immovable, but a target that can calculate the movement trajectory.

Most asteroids and meteorites in the stellar system have motion orbits. Even passing meteors can calculate the motion trajectory through gravitational models after entering the stellar system.

As long as the target of the motion trajectory can be predicted, it can be regarded as a fixed target.

Set the hit time, calculate the position, and fire the gun.

However, the ultimate star destroyer built by humans is not a fixed target.

After the Palesey civilization fired, there was 8 hours of reaction time.

Just move the ultimate star destroyer out of the orbital range of the gamma cannon in these 8 hours and you can avoid the shelling.

For human civilization, moving the ultimate star destroyer is not a difficult task.

Therefore, after a brief discussion, the Human Expeditionary Fleet decided to avoid shelling.

"It is easy to move the ultimate star destroyer, but what should I do if the 12th planet?" Another question was raised.

Now the three fleets of the Carbon-based Alliance need to fight back to the 12th planet, otherwise it will be difficult to engage in long-term combat.

The Mechanical Empire has built a fortress on the 12th planet and deployed a transport ship, assembled into a simple dock for logistical support.

According to the plan, the three fleets of the Carbon-based Alliance need to use the 12th planet as an interstellar stronghold to launch long-term operations.

Therefore, once the 12th planet is destroyed, it will cause a lot of trouble.

"You can consider planetary engines to accelerate the 12th planet, or slow down, to avoid the shelling of the star ring star destroyer's weapons." A senior executive of the Mechanical Empire Fleet proposed a feasible plan.

If only feasibility is considered, this solution is indeed possible.

Planetary engines are not very strange.

After most advanced civilizations develop into stellar civilization, they will try to transform the star system where the parent star is located.

This transformation involves adjusting the planet's orbits, thereby changing the planet's climate and increasing habitable planets.

Moreover, the Mechanical Empire is better at using machinery to solve problems, so the first thing that comes to mind is planetary engines.

"This plan is feasible, but it takes a lot of engineering pressure to install the planet engine within 8 hours and start the engine to push the planet out of the shelling orbit..."

After discussing with several military staff members around Chu Xingyun did not agree with this plan:

"More importantly, the number of spare engines carried in the fleet is not enough to push the planet and needs to be dismantled from the warships. If the Palesey civilization launches a raid at this time, it will be very dangerous.

"Not only that, even if this plan is successful, should the engine installed on the planet be removed? If it is not removed, how can the engine of the warship be solved?"

After a long discussion by the three military staff, Fang Yuan spoke out: "Okay, no discussion of the plan. Just make sure it is better to accelerate the planet or slow down the planet."

A moment later, Lang Xiaonian spoke out: "If our combat idea in the future is attack, then we should slow down the 12th planet.

"After the planet's orbital speed decreases, the orbit of the orbit will shrink and be closer to the star ring.

"If the planet is accelerated, then the planet will fly out of the star system and only choose to accelerate when it needs to escape."

Fang Yuan nodded in agreement with Lang Xiaonian's views, and other senior civilized officials had no objection.

The purpose of this attack on Andromeda α1024 is to continue to move forward, so it is necessary to maintain the offensive momentum. Then slowing down the 12th planet is the correct strategy.

Due to the existence of star gravity, if the planet is accelerated, when the speed exceeds the third cosmic speed, the planet will fly out of the star system.

Of course, the third cosmic velocity of Andromeda α1024 and the third cosmic velocity of the solar system are not the same number.

The final effect of slowing down the 12th planet will not cause the instantaneous speed of the 12th planet to decrease. What is really reduced is the radius of the orbit of the orbit, and the slower the slower the planet will get closer to the star.

In theory, if the star is used as a reference object and the instantaneous velocity of the planet is reduced to zero, then the planet will fall into the star in a straight line.

...

After the response plan was determined, Fang Yuan greeted Niu Dazhi and started to take action.

"First solidify the surface of the planet, otherwise with a gentle force, the planet will explode." Fang Yuan hovered at a height of 30,000 meters, looked at the 12th planet of Andromeda α1024 below, and pointed to the surface.

"From joining the army to now, it seems that the most work I have done is to solidify objects." Niu Dazhi sighed, released his anti-gravity flight ability, and fell down like a free fall.

Niu Dazhi landed on the surface of the planet, shouted loudly, and pressed his hands on the ground.

Strong nuclear force poured into the earth, forming a huge spider web of strong nuclear material, covering a thousand kilometers of ground.

The ground that has been solidified by a strong nuclear network structure and attacks below the galaxy level cannot cause damage to this ground.

Fang Yuanfei fell down, pressed his palm on the surface, shouted deeply, and exploded his force to push the planet.

The planet oscillated and the earth on the east side began to sank slightly downward, but with strong nuclear force solidified, the planet's mantle did not crack, and only a few volcanoes spewed out magma.

Driven by the power of the star god, the 12th planet of Andromeda α1024 began to slow down.

After deceleration, the planet began to slide towards the Andromeda α1024 star, and the planet's orbit began to shrink, gradually shortening from the original distance of 30,000 light seconds to 25,000 light seconds.

The huge changes in the planet's orbits have caused the weapon attack of Andromeda's α1024 star ring to completely fail.

The ultimate star-destroying cannon was also pulled by the gravitational force of the 12th planet and left its original position. Without the need for a evasion plan, it naturally avoided the artillery shooting point.

Eight hours later, the shelling beam of the Star Ring Star Destroyer weapon passed by 300,000 kilometers away from the 12th planet, without even touching the edge.

...

The first round of offense and defense carried out by the Carbon-based Alliance led by humans and the Palesey civilization ended.

Both sides cracked the opponent's attack, and at the end of the first round, neither side suffered any casualties.

In the next ten days, the human ship-to-ship engineering team and the Mechanical Empire cooperated to continue to transform the ultimate star-destroying cannon.

Ten days later, the transformation was completed and the test was successfully completed.

The carbon-based alliance led by humans began its second round of offensive.

The ultimate Star Destroyer Type II begins to enter the charging stage.

Three hours, the recharge is completed.

"Captain, the charging is completed and you can start." Zhao Anya's voice sounded in the communication channel.

Fang Yuan lowered his head and kissed Xiao Sihua's face, saying, "Dad is going to work, I'll play next week, listen to grandparents."

Xiao Sihua pouted, not wanting to separate like this, but she nodded and agreed, raised an unopened holographic game and said, "Then I will play this next week, fast roller skating, and many of my classmates will play this."

"Yes." Fang Yuan smiled and pinched her little face, then turned off the holographic game system, and walked out of the rest cabin.

With a flash, Fang Yuan appeared above the ultimate star destroyer, looking up at the distance where the muzzle was aiming. There was Andromeda α1024 star ring, the star defense system with the strongest defense of the Palesey civilization.

The various teams that cooperated with the ultimate star destroyer began to prepare.

"The ultimate satellite killer II charging is completed, and the energy system self-test is completed..."

Eve gave a thumbs up on Shenzhou: "The fire control system self-test has been completed, and the Shenzhou fire control radar has been successfully connected..."

Immediately afterwards, Ye Zheyu set the parameters: "The shell shooting point is calculated, the muzzle position is adjusted, and the error is 2,000 meters."

If the error of 2000 meters is placed in the land era, then astronomical figures.

However, on the cosmic scale, this error can be ignored.

After all, the 12th planet is now at the light-second distance from the star ring, which is 250 times higher than the range of ordinary naval guns, with an error of only 2,000 meters, which is already very accurate.
To be continued...
