Target Star System - Tenth Planet

"Whoosh~" A small squadron, with the Andromeda-class wave cannon warship as its flagship, entered the outermost edge of the star system.

"Buzz... Buzz..." Blue light began to gather at the muzzle. A few seconds later, ten Kongo-class and twenty Dreadnought-class wave cannons, along with the Andromeda Wave Cannon Battleship, bombarded the tenth planet.

"Crack! Snap!" The diffusion wave cannon's attack completely destroyed the target planet's hemisphere, followed by a sound like shattering glass...

"Whoosh—" The enormous world gate unfolded directly in the planet's high orbit, and the violent energy fluctuations sliced ​​the planet in half and devoured it.

"Beep~..." One after another, Dreadnought-class wave gun warships and Karakum-class battleships disengaged from warp and arrived here.

"Whoosh..." An Executor-class super star destroyer arrived here, accompanied by hundreds of Imperial-class star destroyers and attack cruisers.

"Whoosh..." More than a hundred Wanbao giant-class battleships, accompanied by a large number of Generous-class frigates and Divine Will-class cruisers, arrived here...

In less than a minute, the starry sky was filled with interstellar warships.

"Buzz~" The Gate of the World suddenly surged violently, and then, five Death Star fortresses and one Starkiller planetary fortress slowly flew out from within, arriving at the rear of the massive fleet.

Inside the bridge of the Starkiller planetary fortress

"It has to be said that this is a typical fan-made microcosm, and the world is too vast," Maru said after looking at the various information fed back by the radar.

“Spaciousness is a good thing. Her Majesty the Queen desires this kind of empty universe to merge with her smaller universes,” Demel said, looking up.

“Admiral, this is a long-range detection report from the third planet. There are humans on the target planet, and they are at war with undead enemies.” An adjutant approached Demel.

"Humans? Maru, what do you think?" Demer looked at Maru and asked for her opinion.

“What Her Majesty the Queen wants is a universe that belongs solely to her. If there are native inhabitants, she will conquer them. If the natives cause problems, she will violently suppress them. Her Majesty the Queen has no need for disobedient slaves,” Maru said with a smile.

“I see. Notify the fleet to fire on the undead. As for the native humans, send troops to deal with the undead while simultaneously attacking human kingdoms,” Demel issued the order.

"Yes, Admiral Demel."

"Also, notify the strike cruisers in the rear to send a few more over; there are aliens here," Demel said.

“Yes, Demel Passage.” The adjutant left.

"Report! The reconnaissance robot has discovered the rear area belonging to the Undead." A communications officer came to report.

"A city that looks quite large, but there's nothing inside except some collapsed buildings." Maru made a preliminary analysis while looking at the rising holographic projection.

“Since they are undead, the surface of your large city is just a smokescreen; the real lair is deep underground,” Demel said.

"I see. So the part above ground is just an attractive illusion, and the real main course is underground," Maru said, looking at the holographic projection.

"Notify the base universe to send some people from the Angel Legion."

“Why send the angels? The fleet is enough.” Demel raised an eyebrow.

"After we tidy up the fourth planet and move all the humans there, the wave cannon fleet will directly bombard the third planet. As for the angels, they're for those high-level, potentially planetary-level undead gods," Maru said.

“I see.” Demel nodded, then began to instruct his adjutant and others to forcibly relocate the humans once the Angel Legion arrived.

"Remember, there is only a place for humans in the Empire, not for those alien slaves."

Target planet - a border city

"Gragh..." On the border, a massive undead army was advancing, including not only the lowest-level skeletons, but also high-level units such as zombies and skeleton mages.

"...Death Knights, two of them." The city guard whispered as he looked through his binoculars.

"Tch! Everyone, get ready!" the officer shouted, only to find the soldiers' faces filled with fear...

"...Sigh~" The officer took a deep breath and was about to say something when a strange light suddenly shone in the sky.

"Whoosh—!" A beam of light swept across the distant army of undead, and the violent explosion blasted the army of undead into pieces. The officer even saw a skeleton fly into the sky and then crash to the ground in a mess.

"Woo-woo-woo—!" A horn sounded in the sky, and hundreds of angels flew rapidly across the sky, heading towards the direction from which the undead had come.

"Whoosh...whoosh..." A large number of silver-gray drop pods fell from the sky and crashed straight to the ground. Thousands of Astartes soldiers quickly disembarked from the drop pods and assembled, and then...

"Whoosh! Boom!!!!" Upon seeing the angels appear, the humans cheered. When the drop pods appeared, the humans thought they were part of the angels' army. Then, the cheering human soldiers were caught in the violent blast wave.

"Cough cough..." When the city guard, who had barely survived, coughed and got up, he was faced with the dark muzzle of a bomb gun. As a soldier, he sensed the imminent danger of death and subconsciously raised his hands.

"Whoosh..." In the sky, more than a hundred Wanbao giant-class battleships left hyperspace and arrived at high-altitude orbits of the planet.

"Whoosh~" Tens of thousands of C-9979 transport ships flew down from the planet's high orbit, scattering towards the human kingdom.

"Swoosh~~" Ten C9979 transport ships landed in front of the city, which had been completely destroyed by the Astartes in a short time and all the surviving humans had been captured. Squads of B1 and B2 combat robots then emerged.

“Now, we will take these prisoners.” A B1 commander spoke as he approached Astartes.

The Astartes put away their weapons, allowing the B1 robot to escort all the humans toward the transport ship.

"Whoosh—" Ten minutes later, three transport ships took off, and the Astartes, accompanied by B1 and B2 combat robots, marched towards the direction from which the undead army was coming...

"Oh? That's it?" the system exclaimed in surprise.

"What's wrong?" he asked.

"It's nothing. You'll be able to fully take over this universe soon," the system replied.

"Oh." Xing stopped focusing on the fleet's attack and went off to think about her own things...
