Outside Pluto, the mothership was hovering in space. On its flank, a kilometer-long gun muzzle stretched out, aiming at the position of Neptune.
"emission!"
Following Moro's command, the energy-filled third-generation Star Destroyer Cannon fired out.
On the big screen, there are two countdowns, one showing 5 days and the other showing 6 minutes.
The five-day countdown is the time when the Star Destroyer Cannon hits Neptune, and the six-minute countdown is the activation time of another planet-destroying weapon.
Six minutes passed quickly, and dozens of cannon muzzles appeared on the mothership again, shooting straight at Pluto.
These are laser rays each as thick as the mouth of a bowl. Dozens of them are shot out simultaneously, forming a hollow circle.
In an instant, the ice on Pluto melted away to create a channel hundreds of meters deep.
After the passage appeared, the laser beam at the muzzle did not stop. Instead, it continued to output, expanding the depth of the passage.
…
"what are they doing?!"
At the lunar base, Zhao Yu stared at the gravitational wave detector and asked with some confusion.
"They seem to have launched something towards Neptune. Based on the mass and speed, I speculate that it might be a Star Destroyer Cannon..." Uncle Da explained.
"They're going to blow up Neptune?!"
Zhao Yu frowned, remembering the gravitational wave chaos after Jupiter was bombed, and said: "This is probably another enemy attack. Take the time to repair the second line of defense..."
But the two of them thought for a long time about how the enemy would attack.
"Sir, why don't you stay on the mothership during this period so that you can escape easily if the situation changes..."
"Um……"
Zhao Yu thought for a while, then went to the combat command center again and asked a number of staff officers, but did not get any useful information.
…
Six days later.
On Pluto, the channels ablated by lasers are getting deeper and deeper, and there is only one membrane left to reach the core.
In the middle of the circle of laser muzzles on the inside of the mothership, the muzzle that had been muted suddenly spurted out a bolt of lightning, which penetrated straight into the core of Pluto along the channel.
"Zizzi~~~!"
Lightning struck the membrane instantly, and in an instant, the entire earth's core appeared before his eyes, a golden fireball burning fiercely.
With the addition of lightning, the color of this golden fireball becomes more and more vivid.
Although the Moro fleet no longer has particle black hole collapse bombs that can explode the planet at will, it does not mean that they have no other means to destroy the planet.
In addition to the Star Destroyer Cannon, there are many ways to destroy planets, such as the current method of destroying Pluto, which is suitable for environments without external interference.
"The temperature of Pluto's core begins to rise..."
"The pressure inside the Earth's core begins to increase..."
"Increase the laser power and maintain the channel..."
"The Earth's core has awakened, and Pluto's magnetic field has reappeared..."
"Continue to heat..."
With the coordination of multiple departments on the mothership, in just a few minutes, the temperature of Pluto's core increased nearly ten times, and the ice outside the core began to boil and vaporize.
A large amount of water vapor emerged, and there was an urgent need to find a vent, but this was the outer layer of the earth's core and there was no outlet at all. The water vapor could only stay in this small space and continue to compress.
The temperature of the Earth's core is getting higher and higher, and the pressure outside the Earth's core is getting higher and higher.
"Buzz~~!"
After an unknown amount of time, with a crisp sound, all the gravitational wave detectors on the mothership failed.
"Neptune exploded!"
Moro knew very well that this was the impact of the Star Destroyer cannon arriving on Neptune.
"Pluto is coming soon..."
Just as he was saying this, the ground of Pluto below suddenly broke apart, and the entire planet began to churn as if some kind of creature had awakened from the ground.
"Evacuate quickly~~!"
Each gun port of the mothership went out, and it left Pluto in an instant.
Within a few seconds, Pluto exploded with a bang, completely shattering into pieces, and countless fragments mixed with various elements exploded in all directions across the universe.
At this point, Pluto and Neptune officially announced their retirement.
The mothership only moved tens of millions of kilometers away before stopping again.
This is where the wormhole is located.
"Activate the wormhole and go to the nearest star system..."
The surface of the spacecraft began to spit out negative energy, and as the wormhole emerged, it disappeared into it in an instant.
…
Near the moon, Zhao Yu sat on the giant mothership, staring nervously at the screen with Uncle Da.
On the screen, the gravitational wave curve representing the Star Destroyer Cannon slowly crashed into Neptune.
"Zizi~~!"
Familiar gibberish appeared, and the gravitational wave detector failed again.
"here we go again……"
Zhao Yu took a deep breath and looked in the direction of the second line of defense. There were tens of thousands of newly built spaceships standing ready at a safe distance.
While Zhao Yu was thinking about how the enemy would attack, the system's voice suddenly sounded in his mind.
mission rewards?
Zhao Yu was stunned and thought about it carefully. It seemed that when he first traveled through time six years ago, the system did mention that this was a mission, but it was so long ago that he couldn't remember it clearly.
After carefully reading the system prompts, it was mentioned that the expulsion of the Moro fleet has been completed.
"So, the Moro fleet has left?!"
Zhao Yu could not help but breathe a sigh of relief as the system would not lie. He was also worried that the Moro fleet might have some new attack moves to bomb Neptune.
Now it seems that they were just incompetent and furious, and they just blew up a planet to vent their anger before leaving.
Overjoyed, Zhao Yu looked at the three rewards with delight.
What made him a little regretful was that the title of 'Mysterious Businessman' no longer worked for Blue Star people.
He guessed that it might be related to the fact that he interfered too much with Blue Star, causing the system to determine that they had the same origin.
Although Zhao Yu was very curious about what the mysterious merchant would look like after upgrading, now, this reward was the most useless.
"The title of King of War, destroying alien military units can obtain additional technology points..."
Zhao Yu couldn't help but glance at the space station outside Blue Star.
Who would have known that as soon as the idea came up, I would receive a prompt from the system.
Zhao Yu couldn't help but feel a little regretful. It would be great if he could exploit this loophole. He could build and destroy at the same time and gain technology points.
Finally, he turned his attention to reward three, "Enable the reputation system. Reputation can be exchanged for technology beyond the base level. This is good..."
Zhao Yu made a decision quickly.
"I choose reward three and activate the reputation system..."
