Kneeling before the giant armor space marine, Enri let out a sigh of relief. Even though the other armor being called out to the god emperor in his battle cry, she doubted that such heinous action toward loyal citizens of the imperium of man could be committed by a loyal space marine. They must be filthy Zeno scum dressing as space marines to plunder our planet while its defenses were weakened by the militarium leaving for Tera.

'the old guardsman often spoke about meeting a space marine during his service, how they are the loyal protectors of the imperium and her people. How the green armor space marine is the most compassionate of all.'

'I can see some shade of green in his armor, and he saves us from those Zeno so he can not be a bad person.'

Suddenly Enri noticed another figure appearing behind the robe-wearing space marine, the figure is appear to be a female, for her chest armor seemingly budge out. For her to accompany a space marine then she must be a sister of battle, but what of the wing on her back?

Enri has heard many tales about the sister of battle and their heroic sacrifice for mankind, the most noticeable tale is about a living saint, who has the blessing of the god emperor to be revived and turn the tide of the most desperate battles of the imperium.

'Why would such an important figure like a saint be here? Is the situation of this world that bad?'

Not knowing what to say Enri mumbled to herself. Not noticing the strange language the two figure in front of her are currently speaking, thinking that their voice is muffled by their helmet.

"I apologize for my late arrival, the preparation took longer than expected."

"It's fine, you came just in time."

Wearing full plate armor it seems that Albedo is the closest being to the specification I requested, the layer of flesh imitation metal could also be used as a physical defense in combination with the full plate armor of necrodermis. Arm with a large battle axe readily to cleave any of Momonga foe.

"Thank you... Then shall I dispose of these inferior life forms? I do not wish for you to stain your hand with them."

"No... I intend to save these beings, I believe that those who are currently harming them can help me find out this era's technological level. Eliminate these armor warriors and send them to be analyzed."

Seeing Albedo nod in understanding, Momonga turns to the two girls.

Thank to the big one mumbling the language data have finished complying. Momonga and Nazaric now have a means of verbal communication.

"Now then. Take me to your leader."

Shrinking under Momonga and Albedo's gaze, the two girls make themselves as small as possible. After hearing Momonga in a familiar tone, Enri eases up thinking that the green angel of the emperor change his tone of voice to help her to calm down.

"He really is compassionate, so this is a real space marine, a angle of the emperor."

Slowly standing up Enri replies with a quivering voice.

"Right away my lord space marine, please follow me to our town."

With a shaky leg, Enri mustered up the rest of her courage to run back to her town, even knowing that she currently have two space marine guardians the fear keep swelling inside of her.

'god emperor protect.'

Letting out a silent prayer Enri advanced back to her hometown with their savior.

The silent prayer giving the young woman courage was heard by Momonga.

'Space marine? They refitted the combat force of the ocean to space?'

Wondering is their any mistake in the translation, Momonga stops thinking about such absurd titles and focuses on more pressing matters.

'Sister of battle, god emperor of mankind, it seems that this girl mistaken me for the warrior of this said emperor.'

'God emperor' it seems like these being worshipped their ruler, in a way we are the same, to be controlled by our ruling class mine through the body and them through the mind.

'Stil, I held no pity for these beings, the weak serve the strong, it is not their fault they are weak, so I will use them to further my own goal.'

Reaching the edge of the town, Momonga saw the scenery of a massacre taking place.

'They sure are taking their time, the killing were slow, to savor the torment inflicted.'

The two girls drop to the ground unable to bare the watch the butchering of their home, continuing the walk leaving behind the girls, Momonga prepares to make his next move.

.

"For the emperor!"

The mighty roar shatters the sky, filled with mockery and sadistic pleasure echoing throughout the street liter with fresh corpses. Seeing the loyal citizens of the corpse god Imperium with confusion depression and panic as they being flayed alive, fills Londes with much pleasure.

'Some of them even curse the corpses god, hilarious.'

The planet enjoyed peace, a rarity in this universe filled with horrors. A small amount of radiation ever clinging to the planet make it impossible to be an argri world, nor can it be a manufactory world for its lack of fusion material, many believe that mass radioactive ore mining during the dark age of technology is the cause of the planet environment. However or whatever happens in the past now does not matter, after taking part in the latest black crusades his chaos war band suffer quite some loss. Thank Abadon the despoiler, their offshore unit of emperor children's war band can escape from the eye of terror, but Londes does not feel indebted to the despoiler, so when he feels that the thirteen black crusades are reaching its end and the despoiler war master losing ground, Londes take his war band of three ships, hundreds of chaos marine and leave the losing war.

The crusades end a success, forfeiting out on the glory of opening the great rift Londes is in shock fearing how his battle brother might see him as a coward. Thankfully non of his battle brother disapproves of his decision for there is no glory in death, and they don't want their soul to be devoured by their god just yet.

It have been relatively smooth sailing for their Warband as of late, raiding gene vault, recruiting, and raiding world, everyone is happy even their tech priest is having a laugh now and then. This world and its inhabitants living in the arm of peace, make Londes second stomach chun making him want to barf out his last feast and some nutrients gel.

The timing is perfect With the world militarium force leaving with glee joining the indomitus crusade leaving their world defenseless.

'Hmm.. As if it even matters.'

Even with the full might of this world millions of militarium member, it only add to the challenge of ravaging the world.

But Londes does not come here to be challenged, he came to relax and vent. Taking part in some of the fun at the beginning, Now Londes prepares to let the rest of his men drop down from their ship in orbit while watching over those currently enjoying themselves here.

A ray of green energy ripped through Londes, even protected by his iron halo his terminator armor seem to receive some damage. But the same could not be said for his man, the surprise attack claim twelve of this chaos marine nearly half of his current ground force, the rest of his men are either unharmed or losing one of their limbs.

Soon after the figure of their attacker reveal themself. Skinny figure shining with a grey metallic hue seemingly appears, some arm with heavy cannon cracking with lighting, some held battle glaive with blade warping the very space itself.

Without a moment of hesitant Londes and his man raise their bolter and rain bolt at their enemy, not having armor piercing round is quite a blow to their firepower but with such sustained fire their no doubt that they can destroy these machines.

The necron shooter received heavy damage to their hull some have to be teleported out of the battle due to interior damage. Meanwhile, the melee wielder continues their advance ignoring the rain of bolt impact against their bodies, the damages could be clearly seen but combat effectiveness is not affected. Upon reaching the enemy the necron melee fighter raised their glaive ready to strike down.

To any regular living being seeing in front of them a huge metal skeleton damaged by continuous bolter fire ready to cleave them in half could mentally break them even before the blade could. But the chaos marine by design feels no fear, seeing the world in slow motion as their brain produces more and more chemicals boosting their already fast reflex. The marine drop their bolter and draw their chain sword to block the incoming attack.

Unfortunately, such a move is useless against a weapon that rips through space. The necron glaive easily and cleanly cut in half the chaos space marine along with their weapon.

Londes seeing the destruction of his battle brother, quickly order those still alive to board the land rider and retreat to the extraction site. Using the vehicle las cannon and heavy bolter, Londes order to use such heavy weapon to shoot the necron not caring about the crossfire killing the marine currently locked in combat with the necron warrior. The reckless attack heavily damaging the necron creating an escape chance. After ward the land rides escape from the battle with it engine pushed to it limit. With only a handful of his marine left, Londes swear his revenge, but first he have to regroup at the extraction site and return to his ship.

.

"Hmmm."

Observing the retreating vehicle, Momonga orders the battle damage report.
