Star Iron, building an empire starting with game development

Rear Command Post of the War Zone

"..." The command center was very quiet. Even when the phone rang, people answered it immediately and whispered something to each other.

There was no way around it; after all, sitting in the corner was a Sentinel Miss whom no one dared to offend, not to mention the obvious low pressure emanating from her, which was practically telling everyone else that she was very angry.

“Report… Waaah~” A JCC guard who ran into the command post had just shouted out when he was immediately held down and his mouth covered by the other guards.

"What are you doing!" an angry male voice rang out. The voice was so deep that the sentry sitting in the corner looked up, and everyone else in the command post immediately fell silent, afraid that the young lady in front of them would take her anger out on them.

"Get out of my way, and go get your whips!" The man's voice continued, and he walked into the command post, only to find it unusually quiet. The guards and communications officers stood by, not daring to speak.

"What are you all doing... uh~" Just as he was about to reprimand the others in his general's uniform, he suddenly sensed something was wrong. He turned around and saw someone sitting in the corner, staring at them with a dark expression...

"Excuse me, Your Highness." Seeing the girl staring straight at him, and noticing her clothes and the flag beside her, the general bowed without a word and hurriedly ran out of the command post.

"Divine Metal," the girl spoke, then continued her low-key demeanor...

…………

This is the third day since the girl came into this world. For the past three days, she has been sitting in a corner of the command post, neither eating nor drinking nor speaking, which has made the officers in the entire command post eager to do something but dare not overstep their bounds.

"System, what's going on?" On the third day, the girl, who was finally no longer in a bad mood, began to ask.

"A special world, a special human civilization, everything is special," the system responded.

"Didn't I travel through time again? How come I've become a different person in this world, and my strength has decreased significantly?" the girl said.

"In the past three days, I have been looking at the records of the composition of this world at the World Management Center. This world was created by a god of the main god level. After the creation was completed, the god disappeared, which caused many laws of this world to appear to be chaotic, but they can still function normally."

"As for why you are the way you are now, it's a matter of the laws of this world. I've preserved your original form in the system space," the system said.

"What a nuisance! My strength has decreased, not to mention my... oh, those things are still here." The girl complained, then realized that apart from her strength decreasing due to her new body, none of her belongings were missing.

"Nonsense, those concepts and skills are deeply bound to your soul," the system replied.

"Speaking of which, I feel like there's something wrong with this body," the girl said, puzzled.

"Because this body was on the verge of death before middle age, you were forced to enter this body and awakened a special ability unique to this world," the system said.

"Special ability? Her clothes and helmet look no different from those soldiers'." the girl asked.

"You'll need to find some records of human civilization in this world to know the specifics. All I can tell you is that awakening is a very normal but rare thing in this world," the system said.

"A record of human civilization? I understand." The girl indicated that she understood.

"Speaking of which, when a Star Core's body is on the verge of death, does it awaken? Am I the one who has taken over its place?" the girl asked.

"Not really. If you hadn't come, she would have died directly from the insects' attack. There's no soul of hers in this body," the system said.

"Okay, I understand." The girl nodded and said nothing more.

Day 4 - Outside the Sentinel's Room

"Has the lord still not eaten today?" an officer asked the guard who was carrying the cold food reserved for sentries.

"No, sir, he is still the same as before," the guard replied, shaking his head.

"We need to think of a way~ Today is the day the Knights arrive, and it will be troublesome if the Sentinel doesn't eat~" the officer said with a worried look.

"..." A commotion suddenly broke out in the command building.

"Go and see what happened?!" Upon hearing this, the officer immediately ordered the guards to go in and see what was going on. He didn't want any of the sentries, especially a flag sentry who could boost the morale of the army, to get into trouble.

If anything happens to a Sentinel outside the battlefield, it's a major event that could affect three generations!

"No need." A buzzing sound came from under the helmet, and in the officer's eyes, the sentry had finally walked out of the command post.

"My lord!" All the officers bowed their heads, while the guards on the side knelt on one knee, performing the imperial salute reserved for sentries.

"Whoosh~" In the distance, a spaceship bearing two crossed flags and a red rose at the front flew from planetary orbit toward this place.

That was a spaceship belonging exclusively to the Rose Knights, the flag sentinels, and it was specially sent to welcome the girl.

After the Rose Knights' ship returned to a magnificent spaceship in the planet's orbit, it departed the star system under the escort of a Royal Fleet squadron.

In the room reserved for the Sentinels to rest, the girl looked at the magnificent sight before her, which defied description, and then glanced at the history books of the human empire and books related to the Sentinels that had been arranged by the maids.

The girl didn't look at the history book about the human empire that had made her eyebrows twitch; instead, she picked up a book related to the term "sentinel" and started reading.

—Sentinels: The most important force in the human empire. The value of a single Sentinel is worth the empire trading several heavy fleets and tens of thousands of marines for its survival on the battlefield. While the empire's generals may die at will, Sentinels must live.

The origins of the Sentinels are lost to time due to their ancient history, but for tens of thousands of years since the human empire's birthplace, the Sentinels have been indispensable to the empire.

Sentinels are few in number. With the Empire's hundreds of superclusters and a population of trillions, there are fewer than a million Sentinels, making each one extremely precious.

Before a Sentinel is born, they can be a member of royalty, an ordinary slum dweller, or an alien race that has joined the Empire. They can even be any animal that takes human form after becoming a Sentinel.

But regardless of their original status, once they become Sentinels, their status is comparable to that of the emperor of the empire to a certain extent.
