"If you want to marry your sister, what procedures are needed? Do you go abroad? Or you just have a relationship with the civil affairs department or don't need to go through the procedures at all, as long as you have a long-term chance, you can cause a de facto marriage."

The boy's eyes were very serious, and his pure black pupils stared at Su Jing tightly. It was obvious that he was half-aged in front of him, but Su Jing felt that he was forced to a dead corner. The fan under the rooftop was whirling, and the heat made Su Jing sweat all over, which was very uncomfortable.

"You don't know what 'love' is yet, kid."

"There are contents of brothers and sisters in mythology, including Nuwa Fuxi in our country, Izanagi and Izanami in Japan, Osiris and Isis in Egypt, Zeus and Hera in Egypt... In the era of ancient mythology, ethics and morality were not fully established, which is a very common fact. The establishment of this morality is also due to practical considerations. The combination of homologous genes leads to the combination of recessive defect genes into homozygous... The incidence of genetic diseases among descendants of brothers and sisters is common..."

"One hundred and twenty-five times. But this is not all the reasons." Su Jing took a deep breath and tried his best to organize the language. "Close relatives will cause... psychological age development lag. As a human being whose physiological and psychological have not yet developed, you have not understood one thing, that is... your functional defect in interpersonal communication. The psychological function you get along with others needs to be fully developed through communication with others. You... you need to meet your own social needs through communication with others. Your sister, who can provide you with this psychological need, will block the interpersonal communication training you should have. You do not need to make friends or fall in love. This lack will lead to your psychological development delay..."

"Technically, as long as there is a sister, there will be no lack of subjective feelings between the two of us." The boy retorted coldly.

"Damn... I can't believe that I'm actually discussing this kind of problem with you..." Su Jing twitched her long hair maniacly. He raised her palm high, pointed at the boy opposite, and gritted her teeth and asked, "So, let me ask you a question...Is she sexually attractive to you?"

"…sexual attraction?" the boy raised his eyebrows.

"Yes. You know the Westmark effect. Do you, will you, feel, her sexual attraction to you? The answer is obvious, 'no'! She has no sexual attraction to you, although she is beautiful. And she will soon become one of the most beautiful girls in the world. But your feelings for her are the feelings between relatives, and there are many ways to protect her. Why choose the...the most...the most dangerous way?"

The boy looked at him coldly: "When Westmark was investigating, did he investigate even a pair of telepathic brothers and sisters?"

Su Jing was speechless.

"We are special. We... cannot be separated, just like two sides of the same soul. There is no pair of lovers in the world who can communicate with us in this way. Judging from my deduction, I can't think of any possibility that others can insert into us."

There is still such a possibility that one of the people completely disappeared from this world. This sentence flashed through Su Jing's mind, making his internal organs tighten like they were hit hard.

"In addition, there is also an opposite effect in Westmark's theory, which is hereditary sexual attraction. If you cannot live together in childhood, you will encounter sexual attraction between your close relatives after you meet in adulthood. If you are separated for a while and you may be able to cultivate sexual attraction between each other while practicing interpersonal skills... Why are your face so ugly?"

"……Yeah?"

Su Jing did feel that the blood on his face was rapidly fading away. The boy opposite was standing there. But he looked scarier than any monster. The touch he gave himself was like a hard and cold rock. Did he be such a person before? He knew everything about him, is this the manifestation of his inner demon?

"But, I don't understand one thing. Is interpersonal communication really useful? Do I really need to have a girlfriend?" The boy took a step forward. "What I want is not the same as what they want. I will hurt them. Although it's enough to close my eyes and not look at me, I still feel that I will be very sad."

Su Jing took a step back. The pale and handsome boy shed two shrill tears of blood and tears from his eyes, but he seemed to have no idea. He opened the fairy tale book in his hand and asked with a frown:

"The happy prince in the story will not feel pain as long as he closes his heart. In fact, if he still lives happily in his palace, he will not be infected by the sufferings in the outside world... My sister and I only need to live with each other. As for those girls, they can be used to satisfy their own health, but I can't help but be attracted by them. Every time I hurt them, I will feel tear-like pain and equal happiness... The more I fall in love with someone, the more painful and happier I will feel when I hurt her. I think this may be because of the harm I suffered in my childhood, or maybe because my nature is so ugly?"

Every time the boy took a step, the mark of flames appeared on the ground.

"Are human beings so selfish? Or is this a bad habit in nature? I want to torture, bully, abuse the people I love, and feel my control over them. But when I do this, I feel pain, and suffer for my ugliness and badness. I want to lift them up to the pinnacle of the whole world, but lock their hands and feet with shackles called love. I want to cherish them, but I am controlled by my own despicable **..."

A black flame leaped in the boy's eyes. Su Jing sighed long, his originally pale expression had calmed down. He stared at the boy in front of him and asked calmly:

"Are you my dark side?"

"... In some ways, yes." The boy raised his head, "But in other words, I am also your childhood. Su Jing. I am the young you. Only you can see your weaknesses clearly. I will reveal everything you avoid."

"But you also have a weakness, my childhood." Su Jing raised his index finger, "I am more than teenager than you, and I have experienced stories that you can't imagine. You are filled with unlucky experiences in the first half of your life, and your heart is filled with darkness and violence. But I am different... I have love from others."

Su Jing stretched out his hand and put it on the boy's head: "The things in the world are not just the knowledge you see in books. In your future life, you will meet many interesting people. You realize your extraordinaryness, but you have not yet realized your ordinaryness... You will meet people who can change you and make you realize that this world is not so boring..."

“…”

"One day, you will smile at everything you used to. In your eyes, things that seem very serious are actually just that." Su Jing rubbed the boy's soft hair. "You are a very kind person, so you feel sad every time you hurt someone, so that in order to avoid this pain, you have learned to draw happiness from the pain. I know, I always know. You will meet someone who understands your kindness, as for your sister..."

Su Jing raised his head and looked up at the dark sky of the inner world. There were no stars, but the dark and light-free space was still vast. The ground fire under his feet was extinguishing little by little, the red charcoal turned into hard stones, and the unstable barbed wire fence regenerated into rough concrete ground.

The inner world is collapsing, and the hot and filthy world is returning to the cold and lonely world.

"If you really love her then, just love her. Don't care what other people say. I know, the only thing you will care about is the people you love. The point of thousands of people is just a breeze blowing on your face, but those you love, if they also object, then choose a path from it. Your intelligence is not just for scientific research, to move your head. When facing the difficult-to-choice problem in life, human 'capacity' exists to open up the third choice."

The boy waved his hand and opened it, thinking for a while and said:

"I remember what you said."

"Even if you sometimes hurt the person you like, it is... it is inevitable. There are always bumps and bumps in life. It is very normal for people with arrogant hearts to hurt each other. As long as you learn to tolerate each other, understand each other, and are willing to change yourself for the other... it is not to give up your own self, but to respect each other, you will be able to get along well with everyone."

“…I will write down what you said.”

"Maybe this kind of thing needs to be experienced in person before you can understand it." Su Jing sighed, "So, tell me, where is the sapphire? I think it's time to get out of this place."

The boy pointed to his chest expressionlessly.

"Just kill me, the sapphire will belong to you."

Su Jing looked at him with his head tilted, and the boy did not move.

"Kill you... No, I don't want to do this kind of thing. Although you make me feel very annoying, I have learned to understand and tolerate others. I understand you very much because you are the one I used to... I hate myself, but..."

Su Jing squatted down seriously and looked at the boy:

"I forgive you. Even if I can't get the sapphire, I will say, I forgive you. Su Jing."

When Su Jing finished saying this, the last piece of wall flew back to the ceiling, and the world was transformed into a world of appearance. There was no one on the rooftop, and only a fairy tale album and a pencil were left in front of Su Jing.
