Only you are irreplaceable

My name is Claire Sterling, and today is my No.20 three days in another world.

It was also the day I officially resumed weapon making.

Due to the need to guard against secrecy, Erwin didn't even give me a decent working environment, and asked me to do this directly in the dormitory. I really suspect that the Corps has been too poor recently.

Han Ji followed me to learn the knowledge all day, as if opening the door to a new world, I think her little notebook is full of important points, this...it's the same as when I was in college.

I didn't expect her to be more enthusiastic than me in her work. It wasn't that I could even keep learning if I was hungry.

I chatted with her a lot about materials science, and with her qualifications, I believe she can be a good helper for me someday in the future.After all, it needs to be nucleated｜It needs the assistance of a team to play, and I can't do it alone, unless I don't want this beautiful hair.

By the way, I have a position in the Survey Corps now.

I am now a team doctor, the kind who spends three days fishing and two days drying the net.

Some time ago, I worked overtime and made some simple antibiotics... But my old arms and legs were exhausted, and I could only enjoy Aurora's massage service by acting like a baby.

I didn't expect to take into account multiple directions here, one specialty and many abilities.

Aurora, you see how much I have devoted my heart and soul to you.

I used to aspire to be a conscientious doctor with medical ethics, and resolutely implement the fine virtues of saving lives and healing the wounded.Rejecting medical troubles and putting conscience first will be the code of conduct.

But all these beautiful ideas were shattered when I found out that they used my technology to transform Aurora.

My original intention was to contribute to the development of human medicine, so that more people with heart disease could survive.

Who would have thought that the results of nearly five years of research would be used by those unscrupulous guys to conduct inhumane living experiments.

When I found out about this, I regretted it for a long time, so I kept pretending to record the data and stay in the laboratory to take care of her. I wanted to make up for the mistakes I made.

I am a human being, and I have never seen a real witch. I have been taught that witches are sacred and inviolable since I was a child.

But Aurora is a rare hybrid. Humans are afraid of her abilities, and witches hate her impure blood.

It would be too ironic to say that it was a blessing in disguise. It was because of her special physique that she was able to survive among so many experimental subjects, but if she survived, she would face deeper despair.

After waking up, she could only stay in the laboratory, her body was connected to countless machine wires to supply energy to the heart, and she was injected with a muscle-relaxing fluid day after day, lying on the hospital bed weakly.

The boxy white walls cut off her freedom.

I carefully got along with her with a strong sense of guilt, not daring to tell her that I was the culprit.

Maybe it's because I'm too good at hiding the anxiety in my heart, she guessed the truth not long after waking up.

It's funny to say, but she was cheated out of it unintentionally.

Surprisingly, she didn't blame me and we just became friends.

On the surface, I am still a madman who only cares about medical research, but we have some little tacit understandings.

We know what the other is thinking without saying much.

I began to frantically research how to provide eternal power to her heart. I searched for all available elements and carried out countless failed experiments.

I found a last resort.

On the day I put her on the operating table for the second time, I completed the greatest research achievement of my life.

I knew that she no longer wanted to be a bird in a cage, and I didn't want to help the tyrant anymore, so I blew up the laboratory in cooperation.

If it was an original sin for her to live in that world, then I, who made her suffer for several years, should also be punished.

However, I survived and went to another world.

The level of science and technology in this world is very backward, all human beings live within the three walls, and outside the walls are species I have never seen before - giants.

Aurora arrived nearly two years earlier than me, and when I was still shivering about the new environment, she was already familiar with the way of the army and had a good time in the Corps.

Oh, and she also found a boyfriend.

Yes, she abandoned me for that 1.6-meter short.

But I just said a few words to her, I am happier than anyone else when someone loves her.

No one here has special abilities like her, and everyone is just an ordinary human being.For the time being, I am relieved that no one who knows her true identity is treating her with colored glasses.

I know her longing for freedom in her bones, and her desire to destroy giants.

When Han Ji talked about the tyrannical massacre of giants outside the wall, I felt terrified. I can understand what everyone in the Survey Corps is obsessed with.

So, I decided to help them change the status quo.

In the past half a month or so, I have learned about their existing resources and reserves one by one, and I have to say that the technology tree inside the wall is really crooked and boundless.

Obviously, there are a lot of mineral resources and high-pressure gas technology on the island, but I only want to make three-dimensional maneuvers and fixed wall guns. It seems to me that it is not worth it. It is simply the best example of overkill.

One of the reasons why I didn't want to continue to study weapons back then was that I had experienced war in my childhood.

War is full of blood, cold and disregard for life.

No one will help you just because you are weak, instead they will plunder until there is nothing left of you.

Perhaps the meaning of my rebirth in this different world is to use my power to help more people.

Even if I make these things, it will take some people's lives.

Once the war starts, no one is innocent, we can only look after ourselves and defend the side we care about.

Thinking about it carefully, I have always felt that the various deeds inside the wall are confusing but somewhat logically conflicting.

How on earth were creatures like giants created?

According to Han Ji, giants don't have reproductive organs, so the theory of breeding is naturally untenable.

They also don't have digestive organs, and they won't die if they don't eat or drink. It's just nature to prey on humans...

This is absurd, although it is true that the law of the jungle has always been the law of the jungle.

The history books inside the walls are even more confusing. How much manpower was used to build these three walls so high?According to the industrial development here, how can such a large-scale task be completed every five or six years.Is it possible that the giants will obediently refrain from eating people in the past few years?

And how did it assert that there are no humans outside the walls?Except for the survey corps, no one has ever stepped outside the city wall.Wouldn't it be unfair to draw such arbitrary conclusions in areas that haven't been explored?

No matter how you think about it, it's weird.

Both Aurora and I think that all this is not as simple as imagined, and there may be a huge conspiracy hidden behind it.

If there is still human civilization outside the wall, conflicts will inevitably break out one day, and it will be too late to prepare weapons for counterattack by then.

Leave the external affairs to Erwin and the others. I believe his talent can lead us to victory.

As for me, I will be a scientific researcher making shells or something.

Ah, another uneventful day.
