Tang Ran lowered his head silently.
After a few seconds of silence on the stairs, Luo Zhan heard the little girl say in a low voice, "You lied to me."
Luo Zhan: "I didn't lie to you, it's true."
"You're just lying to me, how could there be such a problem," the little girl stammered, "unscientific remedies?"
Luo Zhan was amused by the little girl's serious expression of discussing academic issues, so he couldn't help but want to laugh, but he still tried his best to hold back: "The science you are talking about is medical science, and my remedies also have science, I just told you Not a discipline."
Tang Ran hesitated for a few seconds, but still couldn't help his thirst for knowledge. He raised his head and asked suspiciously, "Then what subject are you talking about?"
Young Master Luo laughed lazily and started talking nonsense: "Psychology."
"what?"
"Psychologically speaking, being kissed stimulates a pleasurable emotion in the brain, which helps the sensory system to ignore pain to a certain extent."
"… "
Tang Ran fell into deep thought.
Although she questioned the reliability of this recipe, what Luo Zhan said sounded like it made sense.
Luo Zhan looked at the little girl's thoughtful appearance, which made her feel even more serious: "Why, don't you believe what I said?"
Luo Zhan stepped down two stairs as he spoke, and stopped by the handrail of Tang Ran's next step. He turned sideways and blocked the space behind Tang Ran by pressing the wooden escalator fence to prevent the little girl from stepping down and falling.
Then Luo Zhan laughed lazily: "If you don't believe it, I'll explain it to you."
Tang Ran was silent for two seconds and asked softly, "Why does kissing stimulate the brain to produce pleasant emotions?"
"… "
The air in the dark was quiet for a few seconds, and then there was a low-pitched pleasant laugh.
Tang Ran was at a loss: "What are you laughing at?"
"Because this is a great one..." Luo Zhan paused, "academic issue."
Tang Ran pursed his lips and did not speak.
She felt that Luo Zhan was not complimenting her about her problems, but more like laughing at her.
Luo Zhan saw that the little girl was a little annoyed by his teasing, so he had to cough low to restrain the unruly teasing. After thinking for a few seconds, he said: "There are some neuroregulatory substances in the brain, which can affect people's emotions. Kissing only affects the secretion of these neurological substances, and other behaviors can also achieve the same effect."
Tang Ran: "Neural adjustment?"
Luo Zhan patiently explained to the little girl: "Well. For example, a certain neuromodulatory substance promoted by excitation, when the brain is regulated by some external stimulus and its secretion increases, it can enhance myocardial contractility, thereby increasing the Cardiac output, speeding up blood flow throughout the body, stimulating all levels of the system to follow up, and finally…”
Luo Zhan raised his hand and lightly tapped the little girl's forehead, "It will tell you that you are in an excited state of rapid heartbeat, shortness of breath, even wet palms, and fever all over your body."
Tang Ran always has an endless thirst for knowledge in unfamiliar fields. Usually, few people would chat with her, let alone explain her curious questions to her patiently like Luo Zhan.
So when Luo Zhan spoke, she seemed to have forgotten all the unpleasant things in front of her and listened to him wholeheartedly.
After listening, Tang Ran asked curiously, "Do you also have this state?"
Luo Zhan looked at the little girl unexpectedly: "Why ask me?"
"Because, you seem to know it well."
"I do not know."
"Huh?" Tang Ran was at a loss, "Why?"
"… "
Luo Zhan thought for a while, then lowered his eyes and smiled lazily: "Probably hereditary from the Luo family? Neither Luo Xiu nor I have ever experienced this emotional stage. The stimulation and secretion of this hormone requires one's own response to the outside world to reach a certain threshold— You can understand that we were raised in an environment where the lower threshold for reaching a sufficient degree is much higher than others, and it is difficult to get enough stimulation - the external stimulation that makes most people blush and heartbeat is not for us. Enough, so it's hard for us to get excited."
Tang Ran thought for a while, then nodded and then shook his head, correcting seriously: "Everyone said that Luo Xiu has a very gentle personality, and I'm not..." The little girl paused when she said this.
However it was too late.
Luo Zhan narrowed his eyes, leaned on the handrail of the stairs and bowed slowly, and asked in a dangerous tone, "What's wrong with me, little girl?"
Tang Ran lowered his head and put on a serious expression that would never speak.
Luo Zhan raised his hand angrily and hilariously, and ruffled her long hair: "I'm not gentle with you yet? All my gentleness is left to you, little white-eyed wolf."
"… "
Tang Ran still pursed her lips and didn't speak, but the cheeks under the long hair had slowly turned a little brighter.
She counted her heartbeat, and felt the slight hot flashes in the palm of her hand.
Is this what Luo Zhan said about the brain's response to external stimuli
That feeling really seemed pretty good.
Luo Zhan dropped his hand back: "But don't be fooled by Luo Xiu, he is more difficult than me to give emotional feedback to external stimuli - that person only seems to be gentle and gentle, judging by the degree of indifference in his heart, it is probably a The level of a refined iceberg."
Tang Ran was stunned and raised his face: "Why is this happening?"
Luo Zhan's eyes cooled down.
After a while, he snorted softly: "The Luo family's bullshit elite education. The child must leave his biological parents after 12 months of birth, and cannot have close contact until the age of 7. This can completely break the dependence on childhood. , and use this stage to maximize the intellectual development of children in the fluctuating period through professional training personnel."
Tang Ran stayed where she was: "But this doesn't seem like raising a child."
Luo Zhan lowered his eyes and laughed lightly: "Yeah, doesn't it seem like raising a gu."
"… "
Tang Ran didn't know the meaning of raising Gu, but she felt that it was not a good word.
Luo Zhan didn't know what to think, but his eyes suddenly stopped.
After a few seconds, he lowered his eyes slightly and said in a low voice, "I would have probably become the same character as Luo Xiu, but I'm still luckier than him."
Tang Ran asked curiously, "Why?"
"Because..." Luo Zhan raised his eyes, slowly brushed every inch of the girl's facial features, and landed on her lightly closed eyes.
Those eyes used to be beautiful.
Luo Zhan's body twitched with pain, causing him to frown involuntarily. But he still looked into the girl's eyes like a self-abuse, and refused to look away.
"Because something happened when I was 11."
Tang Ran suddenly said, "Is it the incident where you fell down while learning to ride a horse and fell into a coma after being seriously injured for a long time?"
"… "
Tang Ran frowned and said, "If I were Grandpa Luo, then I would only hope that you are alive and well, and I won't care about you."
"..." Luo Zhan clenched his fists slightly.
Tang Ran didn't notice it. After thinking about it, she bent her eyes and smiled: "But this is a blessing in disguise, Luo Luo? After that, Grandpa Luo will definitely pamper you, that's why you have the character as rumored. That's fine too-"
"not good."
Tang Ran's voice was suddenly interrupted by Luo Zhan.
Tang Ran was stunned, her smile faded, and she raised her head uncomfortably—the tone that interrupted her was too fierce, and it seemed to contain a cold and unwilling restlessness.
It was the first time that Tang Ran felt such a somewhat terrifying negative emotion in Luo Zhan.
Then she heard the man grit his teeth and repeat, "Not good at all."
Tang Ran was a little frightened: "Luo Luo..."
Luo Zhan raised his eyes, struggling to entangle painful emotions in his eyes. After a long while, he said in a hoarse voice, "Tang Ran, I don't want to die for such a blessing in disguise."
"… "
Tang Ran was silent, and after a few seconds she slowly lowered her head: "I'm sorry, I shouldn't have said that. It must be painful to fall off a horse, right? If it were me, I would be very scared too."
Luo Zhan's emotions were suppressed to the extreme, and the corners of his thin peach blossom eyes turned red.
If that kind of pain... Then how painful is an accident enough to blind a child
He hates himself for not remembering it till now. The pain in that memory was only borne by the slender and fragile little girl in front of him, and he didn't even have the qualifications to explain his identity to her.
Luo Zhan's silence made Tang Ran uneasy for a long time.
After some entanglement, the little girl finally gathered up the courage to speak and comforted unskillfully: "Those things are over, Luo Luo. You are fine now, and you will get better and better in the future..."
Luo Zhan looked at the girl's Tian Ran eyebrows, and after a long silence, he whispered, "Well. It will get better in the future."
"… "
Tang Ran showed a hesitant expression.
She could hear that Luo Zhan's emotional state seemed to be still very low. According to what he said, the method of stimulating the secretion of neuroregulatory substances in his brain, and then generating excitement...
Tang Ran hesitated for a long time and asked softly, "If I kiss the back of your hand, will you secrete a lot of that neuromodulatory substance and mobilize your emotions?"
Luo Zhan was taken away from that low-pressure mood by the girl's words.
The demon Luo in his heart had long been stepped on by the angel Luo, who was full of self-blame and guilt, and he said helplessly: "That's a joke with you."
"Ah," the little girl sighed in disappointment, "I really thought a kiss would stimulate the brain."
"Theoretically, yes," Luo Zhan said. "Kissing belongs to sexual thorns... a kind of stimulus. This kind of stimulus has a very high impact on neuromodulating substances in the brain. impact can be achieved.”
For example, some kind of small movie that some members of the int team are deeply fond of...
Luo Zhan narrowed his eyes, and in his heart sifted these members into the list of "isolated contact with Tang Ran in the future".
Tang Ran didn't know that someone was already drawing a protection circle for her, and she raised her head curiously at this time: "Then why did you just say you can't?"
Luo Zhan lowered his eyes slightly: "I didn't say it before, because of the influence of the growth environment, Luo Xiu and I have a high threshold range for the stimulation required by the external response - just like the visual stimulation I said, we basically do not have any kind of visual stimulation. What's the reaction?"
Tang Ran was stunned: "Is that so?"
"Well," Luo Zhan nodded, "so kissing the back of the hand, which is only the lowest threshold of stimulation for ordinary people, won't have any effect on us—"
"What?"
Luo Zhan was very lightly wet on the back of the raised hand held by the girl's two hands.
Luo Zhan froze.
After a few seconds.
Tang Ran felt the pulse under the fingertips that had not left, and raised his head in confusion:
"Luo Luo, your heartbeat has accelerated a lot."
Luo Zhan: "… "
