Star Iron, building an empire starting with game development

Target Planet - Imperial Ground Forces

"Buzz—Rumble—"

The violent explosion occurred among the B1 combat robot swarm, sending numerous robots flying in all directions. Many robots were even temporarily rendered inoperable for a few seconds due to the special energy from the explosion.

"Jiruwa~!" A Vulture-class robot fighter jet sped across the sky, emitting a rapid mechanical sound.

"Whoosh—!" In the distance, hundreds of vulture robots and nearly a thousand hyena robot bombers rapidly approached, unleashing a barrage of plasma bombs at a humanoid target on the ground.

"Gurgle~~" Hundreds of Destroyer robots rolled to the target, and the powerful bursts of energy that never stopped completely covered the target.

"Judgment in Flames!" In the sky, an angel raised his sword and unleashed a divine strike at the target on the ground who was pinned down by the destroyers...

"Tap tap tap..." Ten minutes later, a squadron of B1 robots marched in unison over the target's remains, heading towards the target city of the undead.

And there were dozens of such battles in the surrounding area where the superior numbers overwhelmed the inferior.

Starkiller Planetary Fortress Bridge

"We've taken care of one—no, all the undead that attacked the Imperial forces." Maru raised an eyebrow as she looked at the battle report from the front lines.

"Let the troops continue the offensive and intensify the attack." Demel transferred the report in his hand to Maru's personal tablet.

"Let me see... raising two-legged creatures, using sheepskin to make all sorts of things... wait? This says those two-legged sheep are humans?!" Maru exclaimed in surprise.

“Yes, all those kept in captivity are humans, ranging in age from one or two years old to elderly people nearing the end of their lives,” Demel replied.

"Tsk~ Lieutenant, inform Astartes that those aliens and undead should not exist in this world." Maru gave the order to her lieutenant.

"Yes, Admiral!" The adjutant jogged away.

“Do we need to notify Astartes? Besides the combat robots, there are plenty of angels flying in the skies of that planet.” Demel looked at Maru.

“Let the angels and Astartes join forces to attack that underground city belonging to the undead. If I had more options, I would have also called in the Grammer Cavalry,” Maru said.

“It would be a waste to actually call them over, not to mention that the Iron Cavalry only obeys orders personally given by Her Majesty the Empress. Especially since almost half of the Iron Cavalry's military strength has been diverted to Her Majesty the Empress's still-unreturned microcosm due to the Abyss eruption,” Demel said.

"Tsk~ It's all for this." Maru thought for a moment and said.

“Also, there’s no need to send any more Astartes to that planet. The information we just received indicates that, apart from those humans who are powerfully ruled by the undead and cannot be taken away, almost all the humans on the target planet have been taken away,” Demel said.

"Ruled by the undead? Very well, they are not worthy of the Empire's jurisdiction, and the Empire has not found any remaining living people on that planet. So—" Maru finished speaking and looked at Demel.

“Let’s destroy that planet completely,” Demel and Maru said together.

Planet Seven in the Star System

"Beep beep beep~ Beep beep beep~" In space, three million Karakum-class battleships began to gather in a special formation along their predetermined course.

"Whoosh~" A portal opened, and an artificial sun, 500 kilometers in size, was launched and automatically entered the orbit of the seventh planet's satellite, where it began to automatically orbit the planet.

"Toot~~" Three Apocalypse-class aircraft carriers, five Luna-class cruisers, and one Glory Queen-class super battleship disengaged from warp drive and then quietly watched the Karakum fleet assemble.

Target Planet - Underground Area of ​​the Undead City

"My king, all the mechanical puppets and angels that invaded our country have withdrawn and returned to the sky," an alien man reported to the skeleton on the throne.

"Evacuate? I doubt it," the skeleton said.

"My lord!" A succubus rushed in.

"A large number of unknown spaceships have appeared in the sky. Flying units cannot attack them; they are flying too high," the succubus reported.

"..." The skeleton on the throne remained silent, its bony fingers tapping incessantly on the armrest, seemingly deep in thought.

"Rumble~~" The violent ground tremors interrupted the skeleton's thoughts.

"My Lord! A beam of light descends from the sky... Boom—!!!" An alien creature ran into the hall to report, only to be blasted into dust by a beam of light.

"Whoosh whoosh whoosh..." Countless blue beams of light descended from the sky, blasting the great hall—no, this city of the undead—along with the kingdom that once belonged to humanity and was controlled by the undead, into the sky...

In the sky, over a hundred Kongo-class wave cannon warships, along with nearly a thousand Murasame-class and Isokaze-class ships, unleashed a barrage of full-power wave cannon fire at the ground, cratering the target planet's continents. The fleet then shifted to either side, and then…

"Whoosh—boom boom—..." A thick green beam of light struck the planet directly. The violent explosion triggered a chain reaction that caused the target planet to disintegrate, with large amounts of planetary debris flying everywhere.

World Management Center

"The problem is solved. That undead transmigrator was blasted to smithereens by Karakum's wide-area cannon," the system said.

"Transmigrators who are immortal? I remember these transmigrators are supposed to be quite resilient to death, aren't they?" Xing asked after expressing his surprise.

"It's just an undead being; your angels can handle it, and your divine power can shred it to pieces. The wide-area cannons assembled by the Karakum fleet are nothing, but that artificial sun has your divine power within it," the system said.

“I see, so this universe…” Xiao looked out at the vast space.

"The transmigrator has disappeared, and the record of which transmigrator belonged to the World Management Center has been erased. This universe is now yours," the system said.

"That's great, I'm going to bring over all my game universes right now." Xiao chuckled.

"There's an additional piece of information. When that transmigrator disappeared, I detected a faint reaction indicating that the transmigrator's soul crossed the world's boundary and returned to its original world at the time of death. These are the coordinates of the Sea of ​​Nothingness in that world." The system pushed something to Xing.

"A blue star?" Xing raised an eyebrow, indicating his confusion.

"That planet is severely polluted by industry, and humanity is suffocating under the oppression of those wicked tycoons. So, how about we go and liberate those ordinary humans who have been reduced to beasts of burden for generations?" the system said with a smile.
