"We are in the cave, come in, there are interesting things here."

"Oh, wait, the ground is a little dirty and slippery. I took off my shoes. "

Boom, boom, suddenly there was a loud noise and creaking sound in the cave.

"Help, sister, come and help us."

"Hey, what's the matter? I'll be right there, waiting for my sister. "

There was another thunder, and the hole collapsed. "

I was awakened by the rolling dust waves, and I was sweating all over.

I clearly remember that my two younger brothers were buried in that cave. But when I went down the mountain to ask my parents for help, my parents told me that I didn't have a younger brother. I was the only child in my family, and everything that belonged to my younger brother was gone, as if it had never really existed.

But I know it's not like that. Since then, I have had this dream every few days. My parents think it's just a dream, but I don't think so.

Then I couldn't hold back the constant noise. My parents called the workers and dug up the cave. It was empty, but I couldn't find my brothers. There is only one stone carving shaped like an old desktop computer.

This incident became evidence that my parents tried to persuade me not to have a younger brother, and I almost believed it. In a flash, ten years passed.

However, last night, I had this dream again, which reminded me of the little things I lived with my brothers, so I decided to go to the cave again.

It was a weekend, and in the early morning, I secretly left home and walked to the hillside. My parents have never allowed me to go to that mountain since that happened. I really haven't been here for so many years. Soon, I came to the hole again. In fact, it should have been filled long ago, but for various reasons, it is still open. I stroked the stone at the mouth of the cave, still so wet, like an open devil's mouth.

I took a deep breath and bravely walked into the cave, which was also my deepest nightmare. After so many years, the situation in the cave is exactly the same as that of that year: wet and muddy ground, rotten and turbid air, and computer-shaped stones still stand there so abruptly. I believe my brothers showed it to me. The disappearance of my brothers must have something to do with this stone.

I approached the stone and looked at it carefully, as if I were looking at a sleeping demon. After several rounds of forgiveness, I decided to touch the stone. When my finger touched the stone, I suddenly found that the texture was definitely not the texture of the stone. It's too greasy and even a little elastic. Just when I was surprised, a voice suddenly appeared in my ear: "Hello, please tell me your name."

I shouted once and turned to run, but suddenly I remembered the scene in my dream. It was obviously my brother's voice, so I stopped. Over the years, I have always regretted not coming in with my brothers. Anyway, I believe that with me here, I can definitely protect them. I tentatively replied to the stone: "Sophia, my name is Sophia."

After creaking, the voice in my ear rang again: "Wrong, wrong name, you still have two chances". Wait, I'll think about it. "Squeak, mistake, incorrect name, you have one more chance, make another mistake and turn it off." I quickly covered my mouth. Although I don't know what it means to turn off the computer, it is definitely not a good thing. By the way, I remember, its voice is my brother's, so try it at last. I cleared my throat: "Sister, I am a sister." This time, there was no creaking sound. That "stone" emits strange blue light, and two figures emerge from it, which is exactly what my brother looks like in my memory and dream.

"Brothers, it's all my fault. I should always be with you. Now we will never be apart? " I burst into tears and rushed to the two figures, but they were empty. At this time, my brother's voice came from my ear: "I am not your brother, I just chose this form and voice to communicate with you." I am the stability point of this world, a machine system used to maintain world stability. ""What about my brothers? Did you kill them? Give my brother back to me! " I shouted a little hysterically.

The machine replied, "I'm sorry about your brother." I slept for a long time before I was awakened by mistake, so I can only erase all the recent memory tools from this world. " This is necessary to protect the stability of the world. ","erase? What do you mean? Does this mean making them look as if they have never appeared? " The machine replied, "Yes. ".I asked tearfully," Then why do I still have their memories? "You know how much I have suffered over the years. I think about them every day, but I'm not sure if they really existed! " The machine replied, "I'm sorry about this, because you are in an uncertain state. We are not sure whether to erase you or remember you clearly." However, if you want to save your brother, there are ways. "

I quickly sorted out my thoughts. "What should I do?" . "Ha ha, don't be nervous, it's actually very simple!" The blue light of the machine gradually disappeared, and a small square table appeared in front of me with three boxes of red, yellow and blue on it. "These are three Pandora's boxes. Each box can start a program that changes the world. You need to choose one of them. The results of the election of representatives are as follows:

Red Box: When opened, the world will be formatted, but your brother and your family will live in a parallel world.

Yellow box: directly erase the memory of my brother, maintain my present life, forget my brother and move on.

Blue box: Go back to the time when your brother was erased. You will be cleared instead of your brother, and your brother will be able to go home.

Please make a choice within one hour. If you exceed the time, I will automatically delete you. "

Seeing this, I fell into a long silence and pain. Yes, by choosing the red box, my brother and my family can be together, but everyone else in the world will die, which is really unfair. If I choose the yellow box, I can get rid of the guilt for my brothers over the years and live a normal life, but that is unfair to my brothers. But if I choose the blue box, I will really see the world again and leave my father, my mother and all the people I love and love me.

With the passage of time, I looked at the hourglass of countdown and finally made up my mind: "I choose, blue box, let my brothers live with you." The machine seemed lost in thought and stood still for a few seconds. "Would you please confirm your choice? From then on, you will lose all traces of existence in this world, and no one will know the sacrifices you have made for everyone. Are you sure you still want to choose like this? "

"I'm sure," I nodded to the machine seriously, "but I hope to say goodbye to my parents, although I know they will never remember me again." "Well, as you wish, please leave with your box. You should hurry. It's not far from an hour. You should open the box before the time. " As he spoke, the hourglass floated above the box. "Don't worry, only you can see this box." I hugged the box, turned and ran out of the hole and ran home.

At this time, the sun has risen and mom and dad are preparing breakfast. "Hey, my lovely daughter is back. She wants something to eat. Dad will do it for you right away. " Dad was still very enthusiastic, joking with me and suddenly saw tears on my face. "What's the matter, who bullied my baby?" . My mother is studying a new dish with a recipe. Hearing this, she also turned to me: "What's the matter, my dear daughter, talk to my mother?" . I watched the time left in the hourglass getting less and less. I know I don't have much time. I gave my parents a big hug. "Dad, Mom, I love you and I will always love you." Afterwards, I opened the box with my parents' doubts.

After a burst of dizziness, I came to play with my brothers, who were playing around me on the hillside. I know I have to go down to the cave before my brothers can save them. So I told them to go home first, and then I went down the hole by myself. In the hole, I saw the machine. I touched the machine. The machine is on. Ask my name. I tried to answer "Sister". But this time, the answer is wrong. I answered two answers, but they were still wrong. The machine raised a strange yellow light, and I was gradually sucked into the yellow halo. I know, I'm going to be erased. Just when I was ready to accept my fate, I found that my brothers had actually gone down the hole: "No, don't take my sister, don't". They came running and grabbed my leg.

"Let go, brothers, if you are dragged in, it will be erased." The younger brothers didn't stop: "No, I love our sister. We must be together and die together. " . In this way, together, we were sucked into the yellow halo.

But, strangely, we opened our eyes again. In the dazzling yellow light, I heard a voice, "No. Planet: M34-4602 15 1-B, the experimental test is qualified, continue to develop and continue to investigate. " In the confusion of my brothers and me, a man in a wide robe came over: "Hello, Sophia, congratulations on passing the test on behalf of your world and winning the right to live for your planet".

I left my brothers. "What, you mean this is all a test?" . The man replied, "Yes, there are many civilizations in the universe. We should observe and identify them to prevent them from destroying the stability of the universe. This test is based on human nature. No matter which box you choose, your planet will be erased. " . "What, so you didn't mean to destroy us?" The man shook his head and said, "No, the key is not which box you choose, but your performance in the whole process." As far as choice is concerned, the red thought of harming others and benefiting oneself, the yellow passive thought and the blue self-harm thought are all disapproved by the universal civilization. You can survive because when you humans face the final fate, the power of love transcends everything, so you survived. "

Just when I wanted to ask something else, I saw the man pat me on the head with his hand. Then, in the blink of an eye, I got out of bed. I just wanted to find out what was going on when I heard something outside: "Sister, sister, you are awake, let's go out and play!" " "I looked out of the window, and the sunshine outside was really beautiful.
