My childish eyes looked straight at the board full of test results. On the left was a chaotically written chemical formula. Everyone looked at it solemnly before writing it down on the brown paper. I glanced at the letters on the paper of the man sitting to my right.

“Father, aren't you bored? Why do you have to read something this complicated?” I asked curiously.

“Time and your spirit will answer that question,” the father replied immediately. Then he took my hand and led me past the board and out of this room.

The light from the window filtered through the door, casting long shadows across the hallway. When his father's toes touched the shadow, he stopped. Taking a deep breath, he dragged me into the room following the light. The first moment I saw colorful test tubes on the table. Some had faint smoke floating on their faces. Some are constantly simmering. There were many beakers and jars lined up.

A girl with shoulder-length hair moaned incessantly. Maybe it was because her fingers were swollen and red. Dad leaned down and whispered softly to me that it was frostbite. Father slowly scooped some white cream from a beaker and smeared it between her fingers. After only a moment, the wound subsided and gradually became smaller. That moment made me appreciate the word "science"

Dad put on goggles and gloves on me and took me into another lab. The interior appearance is completely different from the previous room. The atmosphere is a closed room on all sides. In the center of the room was a steel box with wires all over the room, resting on a steel base. Next is a computer that projects a diagram of the working system.

Dad lightly pressed my fingers on the keyboard. Suddenly, dirty water continued to flow along the path. Then it stopped in a large metal box that vibrated rhythmically. Dad lifted my finger and touched the keyboard once more. The water droplets were slowly distilled until they were incredibly clean and clear. This system is called “Clean water filter” is said by Lieutenant General Ishii.

The inventor of this system was praised by the Emperor of Japan. Because a clean water filter can distill urine into clean drinking water.

“What about the bitterness hidden inside?”

After that experience, I had the opportunity to watch my father's work in the Epidemiology Research and Clean Water Development Center many times. Even though every time I received almost no theoretical knowledge at all. But it made me understand science more.

Misty clouds covered the sky until it was completely dark. Rain poured down all over the factory. Drops of water hitting the concrete floor It splashed on my legs until it felt wet. The delicate body of the twelve year old was completely soaked.

I quickly ran into a large dilapidated building to take shelter from the rain. The building's sign is marked with the words “731.

unit”

This is where the change began. Because in the past two years, Father has never brought me to this building even once. Why?

Rainwater erodes the concrete. In the concrete trench, there was a faint amount of blood dissolved mixed with water trapped inside. My eyes studied the building before I stumbled upon something. I tried to look at it with curiosity. So I decided to immediately follow the entrance to the building.

No…impossible!

A brown-haired man with a skinny body His abdomen was full of knife wounds. He put his hands on the ground and dragged his wrinkled body towards my feet. I'm trembling. His body couldn't move. It only calmed the fear mixed with disgust. He looked at the man with his hands on his soft feet.

“Let…let me go,” he said softly in a Chinese accent.

The thin man's short sentence was like a three-faced stick that hit me hard on the head. Tears streamed down my cheeks. I don't know if it was fear or pity. He looked into my eyes as if he was begging for my life from death in his last days.

What happened? Why did his body look like this? So why did he have to beg for his life from a small child like me? What should I do?

“Who is that kid?!” a doctor shouted as my thoughts became distracted.

"Oh, that's Lord Yamato's son," another doctor replied.

Upon hearing the answer, the two doctors quickly rushed in and carried my body out of Building 731. No matter how hard I tried to fight, I couldn't resist the strength of the two strong men. The last picture I saw that day was of an old man wiping away tears that had slowly flowed out and then gently folding his hands together on the floor of the building in prayer.

That rainy day lesson taught me that there was a whole new world at my father's research center that he never mentioned. A world that smolders with an aura of terror. I spent several months planning to investigate the history of Factory 731, and then the opportunity arose…

Smoke of soot from burning decay

Dust floating around on the cliffside

then spread through light at a strong rate

It was a cloudy sky, contrasting with indigo.

Smoke billowed throughout the treetops before drifting into a completely gray sky. It swirled throughout the air and spread out into a stream. Its smell was like burning blood. The picture below was of small and large buildings stacked together, obscuring the source of the smoke. I wandered through the crevices of the building for over several hours, searching for the source of the enormous smoke. Along the way, a fully clothed doctor walked past and met me by chance.

“What are you doing here?” The gruff voice that came through the mask made me flinch.

“Uh…Lieutenant Ishii asked me to come and inspect…the log.” That's right! The word log is an important secret code for this operation. I heard about it when my father was researching a cure for syphilis in the lab. Even though I don't know what it means, it's a good clue to finding answers from now on.

I picked up my pace until I reached my destination. The source of the smoke was the ashes of corpses that had been piled up and set on fire. Some bodies were covered in blood. In some cases, the tendons were torn into pieces. Or it may be concluded that There were no dead bodies at all. I could only stand and mourn the thousands of dead bodies with sadness.

“Where do these corpses come from?”

That was the sawmill about two meters from the pile of corpses. It looks like a wide courtyard covered with a tin roof. A stocky man had his arms and legs pinned to the bed in silence. Soon, a large saw moved down and cut his leg slowly but sharply. When the flesh came into contact with the sharp edge of the knife, the chubby man screamed at the top of his lungs, his mouth wide open, his body trembling, sweat all over his body.

His voice stopped when his legs were completely separated from his body. The doctor lifted his legs and put them down. Take turns and connect back again. Of course, the body's nature will not accept a new organ using this type of graft. The man was heartbroken and finally died. This is where the word "log" comes from.

Looking up, there was a steel frame separating the roof that was intricately wrapped with ropes. A doctor tied the end of a dangling rope to the ankle of a petite female captive. Just for a moment The doctor shook his hand off the rope. Leaving the little girl writhing in mid-air for two minutes and forty-six seconds. He wrote down the results of the experiment on a piece of paper with the title “

The duration of human survival.”

Several days later I saw a captive running quickly out of a dark room. But because of the drug As a result, he was completely exhausted. His face looked tired. His steps were slow and irregular. Sometimes he almost fell down and lay flat on the ground. I couldn't stand it and rushed to wrap my arms around his body. The captive looked at me with gratitude. He gently caressed my head and used the last moments of his life to tell me everything.

This captive, named Long Cheng, was taken captive when the Japanese invaded Manchuria. He said that this place was established in the name of It's called the Center for Epidemic Research and Clean Water Development, but in reality it's used as a place to test various diseases or biological weapons. Using people as test subjects and without injecting any anesthesia at all.

This was because Lieutenant General Ishii feared that the anesthetic might distort the results of the experiment. Every piece of log was then cut into the body, organs were cut, or even toxins were injected into the body live. It was certain that no captive would be able to survive here, including Long Cheng.

He is a potassium cyanide lab rat. which initially results in muscle weakness, nausea, vomiting, and damage to the nervous system until eventually death. Before being taken and gassed in a darkened room, Long Cheng overheard the doctor talking: If the captive eats until he is full, it will preserve his life for a period of time.

This is because the stomach contains acid that helps digest food. He ate until he was full and survived longer than anyone else.

After Long Cheng poured out all his feelings, He vomited violently. The area around the mouth started to turn purple. Panting like a demon's howl Then he leaned on my shoulder before finally dying. Long Cheng was not the first person I had the opportunity to witness the final moments of his life. Previously, captives afflicted with syphilis or cholera had similar ends.

Up until now, the images showing the horror drama that came through in stages pierced the depths of my feelings. It was as if two years of witnessing various technologies had cost the lives of thousands of captives. Definition of a scientist What father said “It takes time and soul” is just a contrivance to make it look good.

Dad never had a scientist's spirit! Dad was never humane!

“Forget these bad memories.”

There was a sawmill about 32 meters away from the pile of corpses. A burly man had his limbs pinned on top.

bed with calm He…uh…he was crushed by a large saw, crushing both of his thighs until they were completely torn, then…uh…

He screamed at the top of his lungs in pain.

That was a sawmill about 16 meters from the pile of corpses. The man…uh…I don't remember his appearance.

He had his arms and legs pinned to the bed in peace. He…uh…he was crushed by a large saw that crushed both of his thighs.

He was torn apart. No! He'd just had his thigh cut with a knife. Then…uh…he cried out at the top of his lungs, NO! He didn't

cry

That's… Where is that? I saw a man lying motionless on the bed. No! Is he sitting or what is he doing? what happened? Why don't I see anything?

Long Cheng was a potassium cyanide test rat. He quickly ran out of the dark room. As a result, the amount of toxins still does not enter the body. He spared every minute before his death to tell me the whole story until he lay dead on my lap.

Long Cheng was a rat experimenting with potassium…cium…cyanide. He ran away from…somewhere in no hurry. He…uh…spent time before his death to tell me the whole story. Until…uh….he walked away cheerfully.

His name is...I forgot. He said he was a victim...a victim of what? yes! What happened to him? Why is my memory starting to disappear?

"Memories come back"

Yes! I remember now. My name is "Takeshi," Dr. Yamato's son. The incident started with my father taking me to see science. two years ago Now I'm encountering a new world that my father never talked about. It is a world of evil. world of depravity The images of the deaths of one captive after another still haunt my memory.

Later that day, I told my father about what I had seen in Laboratory 731, as a reminder that this agency was crueler than he knew. I urged my father to pack up his things and leave this place immediately. But of course Dad didn't want that. Because doctors who work in this unit will receive better benefits than general doctors.

When I was at my wits' end, I threatened my father that I would reveal the secrets of this agency to the people all over the world. So the father agreed to run away, but there was a condition. “I would like to research biological weapons one last time.” This time, there were more than twenty captives lined up in front of the board. Lieutenant General Ishii forced everyone to open their mouths all the way to their jaws.

Then, toxic substances are scattered from the sky and spread throughout the air. then enters the captive's body through the mouth and breath

Meanwhile, the wind changed direction to the opposite side. The anthrax in the air curled in the air before hurtling towards the doctors and soldiers. The crowd of soldiers in that area panicked and ran away in chaos. Of course, the intensity of the poison and the speed of the wind were faster than a person's footsteps. One thousand seven hundred soldiers and doctors were instantly destroyed by the anthrax and succumbed to their deaths. One of them is “Lord Yamato,” my father.

This was the deepest wound in a twelve year old's heart. If I could negotiate for Dad to take one last break from work. Today, Father's tall and warm body will probably be sitting next to me, waiting to answer my question like before.

From that terrible monsoon I had to go crazy for several days. Therefore he was sent to receive treatment for his mental illness with Dr. Hiroshi. The doctor promised me that he would program me to erase all bad memories. I am truly impressed by Dr. Hiroshi. He helped me even though we never knew each other before.

But…why do I still remember my father's story?

“Five, four, three, two, one, wake up from your subconscious right now.”

I woke up from a dream on a clean white bed. It feels as if everything has just happened not too long ago. Doctor Hiroshi is seen taking notes in his notebook.

“What are you writing?” I asked as he was writing diligently.

“No….nothing,” he replied suspiciously.

I sat up on the bed and quickly grabbed the piece of paper. Until the lower right corner of the paper was torn because of the force of the pen resisting the force of the pen. On that piece of paper, there were various technologies that I had described. along with many more chemical formulas The last line is the anthrax summary that remains blank.

“Doctor betray me?!” I shouted.

“No, take it easy.”

“I put my trust in the doctor to heal my memory. But the doctor revived it to get these theories.” I clenched my sweaty hands tightly.

“The doctor's relatives are the captives in this incident. He had anthrax applied to his skin to test the severity of the disease. But because of his relatively good immunity, he survived with bumps all over his body,” the doctor tried to explain.

I'm not interested in any explanations or excuses. He raised his clenched fist and punched the doctor in the face. I quickly jumped out of bed and picked up a knife from the table, intending to take the doctor's life. At that moment, the doctor grabbed a knife to protect himself as well. I pushed my hand back before stabbing and swiping the knife down again. But the doctor was able to lift the knife and resist my force.

“Yamato's life is a dead life. As for the doctor's relatives, he still has to breathe. Which is more important: forgetting the dead or treating the living?” The doctor stressed.

I swung the knife in a circle and threw it in a straight line. But Dr. Hiroshi can still dodge as before. The knife flew past his rough face and stuck into the wall. I hurriedly walked to pick up the knife. But Dr. Hiroshi stretched out his arm and raised his knife to trap me.

“How well do you understand the word science?”

“Don't fool me with words like my father did,” I said harshly. “Science is a waste of time, energy, willpower, and even life. In exchange for technology to help humanity.”

I was stopped by this sentence. Every word repeats in a loop of thoughts. It reflects to me that “In the past, I thought my father used fancy words to impress me. Then he sought new knowledge by killing others until finally his father had to end his life like a snake charmer who died because of that snake. It's neither right nor wrong at all.”

Father may have done something wrong in this inhumane experiment. But Father was willing to gamble his life in exchange for various sciences. That's what we call "science".

I decided to devote the rest of my life to it. To invent and produce drugs with ingredients similar to current penicillin. We call it "

ATT731”

It is used to inhibit anthrax, which is a bacterium. This type of drug has more side effects than penicillin, including pain and rashes around the body. But it will not affect mental anxiety.

although

ATT731

It will be created imperfectly, but it is the first step towards making science-minded people The next generation is dedicated. Their “time and soul” went into creating science. New theories and knowledge that are beneficial to the public

I leaned down and paid respects to the image of a warm-hearted man named “Yamato” at the cemetery of those who died in the war. I believed that "Father never lies to me."
