Chapter 49

Tang ran lowered her head in silence.

After several 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 cheat you. It's true."

"You're just lying to me. How could there be such a mistake?" the little girl stammered. "Unscientific prescription?"

Luo Zhan was amused by the little girl's little expression of serious discussion on academic issues. However, he tried to hold back: "the science you are talking about is medical science, and my folk prescription also has science, but what I'm talking about is not a discipline."

Tang ran hesitated for a few seconds, but still could not help his curiosity. He raised his head and asked suspiciously, "what subject are you talking about?"

Young master Luo laughed lazily and began to talk nonsense: "psychology."

"Ah?"

"Psychologically, being kissed stimulates the brain to produce pleasant emotions that help the sensory system ignore pain to a certain extent."

“……”

Tang Ran is lost in thought.

Although she doubted the reliability of this folk prescription, what Luo Zhan said seemed reasonable.

Luo Zhan looked at the little girl's contemplative appearance, amused her mind to be more serious: "how, don't believe what I said?"

As Luo Zhan said, he stepped down two stairs and stopped by the handrail of Tang Ran's next step. He turned to his side and blocked the space behind Tang ran by the wooden escalator fence, so as not to let the little girl step on it and fall down.

Then Luo Zhan was tired and lazy to smile: "which words do not believe, I explain to you."

Tang ran was silent for two seconds and asked softly, "why does kissing stimulate the brain to produce pleasure?"

“……”

The air in the dark was quiet for a few seconds, and then there was a muffled, happy smile.

Tang Ran is at a loss: "what are you laughing at?"

"Because it's a great one..." Luo Zhanyi, "academic issues."

Tang ran pursed her mouth and did not speak.

She felt that Luo Zhan was not exaggerating her problems, more like laughing at her.

Luo Zhan saw that the little girl was a little annoyed by himself, so he coughed in a low voice and restrained the improper teasing. Thinking for a few seconds, he said, "there are some neuromodulators in the brain that affect people's emotions. Kissing just affects the secretion of these neurotransmitters, and other behaviors can do the same

Tang ran: "neuromodulation?"

Luo Zhan patiently explained to the little girl, "well. For example, when the brain is stimulated by certain external stimuli and its secretion is increased, it can enhance myocardial contractility, increase cardiac output, accelerate blood flow throughout the body, and stimulate the follow-up response of all levels of system. Finally... "

Luo Zhan raised his hand and gently touched the little girl's forehead. "It will tell you that you are now in a state of rapid heartbeat, shortness of breath and even moist palms and fever."

Tang ran always has an endless thirst for knowledge in unfamiliar fields that he has never been exposed to. Usually, few people would chat with her, let alone explain the curious questions to her patiently like Luo Zhan.

So from Luo Zhan's mouth, she seems to have forgotten all the unhappiness in front of her and listened to him wholeheartedly.

After hearing this, Tang ran asked curiously, "will you also have this kind of state?"

Luo Zhan unexpectedly looked at the little girl: "why ask me?"

"Because, you seem to know it well."

"I will not."

"Well?" Tang Ran is at a loss, "why?"

“……”

Luo Zhan thought for a moment, drooped his eyes lazily and said, "maybe it's from the Luo family? Neither Luoxiu nor I have experienced this emotional stage. This hormone is stimulated to secrete a certain threshold of its own response to the outside world - you can understand that our growing environment makes us reach the threshold of sufficient level, which is much higher than other people, and it is difficult to get enough stimulation - the external stimulation that will make most people blush and heartbeat is not enough for us, so we are difficult to have fun Try your best. "

Tang ran thought for a moment, then nodded and then shook his head, seriously correcting: "everyone said that Luo Xiu is very gentle, and you do not..." The little girl stopped here.

But it's late.

Luo Zhan slightly squinted, holding the handrail of the stairs and bowing slowly. In a dangerous tone, he asked, "what's wrong with me, little girl?"

Tang ran bowed her head and put on a serious expression that she would not open her mouth.

Luo Zhan raised his hand and rubbed her long hair: "I'm not gentle with you? All my gentleness is for you alone, little white eyed wolf

“……”

Tang ran still pursed her mouth and didn't speak, but her face under her long hair was slowly showing a little Yan color.

She counted her disordered heartbeat, felt the warm feeling in her palms, and jumped off again in some novelty --

is this what Luo Zhan said about the brain's response to external stimuli?That kind of feeling, as expected, seems to be good.

Luo Zhan dropped his hand: "but don't be deceived by Luo Xiu. He is more difficult than I am to produce emotional feedback on external stimulation - that person only looks gentle and gentle. According to the degree of indifference in his heart, he is probably a perfect iceberg level."

Tang ran was stunned and raised his face: "why is this so?"

Luo Zhan's mood cooled down.

After a moment, he sniffed: "Luojia's bullshit elite education. Children must leave their biological parents 12 months after birth and cannot have close contact until they are 7 years old. In this way, we can completely stop the dependence in childhood, and use this stage to develop the children's intelligence in the fluctuating period to the maximum through professional trainers

Tang ran stayed in the same place: "but it's not like raising a child like this."

Luo Zhan lowered his eyes and scoffed: "yes, it's like raising poisonous insects."

“……”

Tang ran doesn't know the meaning of raising Gu, but she feels that it's not a good word.

Luo Zhan did not know what to think of, the mood dark turn eyes suddenly stopped.

A few seconds later, he drooped his eyes and whispered, "I would have been the same character as Luoxiu, but I'm still luckier than him."

Tang ran asked curiously, "why?"

"Because..." Luo Zhan's eyes raised, slowly brushed every inch of the girl's facial features and landed on her gently closed eyes.

Those eyes used to be beautiful.

Luo Zhan has a kind of pain in his body. He can't help but frown. But he still looked at the girl's eyes as if he were masochistic and would not move his eyes.

"Because something happened when I was 11."

Tang ran suddenly: "did you learn to ride a horse and fall down, seriously injured and unconscious for a long time?"

“……”

Tang ran frowned and said, "if I were grandfather Luo, I would only like you to live well. I will not care about you."

“……” Luo Zhan clenched his fist slightly.

But Tang ran didn't notice. After thinking about it, she bent her eyes and laughed: "but you can be considered a blessing in disguise, Luo Luo? After that, grandfather Luo must connive at you, so you will have the character like the rumor. That's good too -- "

" not good. "

Tang Ran's voice is suddenly interrupted by Luo Zhan.

Tang Ran is stunned and the smile disappears. She looks up uneasily. It is the tone that interrupts her so fiercely that it seems to suppress the cold and unwilling impatience in it.

It is the first time that Tang ran felt such a terrible negative emotion in Luo Zhan.

Then she heard the man gritting his teeth and repeating, "not at all."

Tang Ran is a little scared: "Luo Luo..."

Luo Zhan raised his eyes and struggled with the painful emotion in his eyes. After a long time, he said in a hoarse voice, "Tang ran, this is a blessing in disguise. I don't want to die."

“……”

Tang ran was silent. After a few seconds, she slowly lowered her head: "I'm sorry, I shouldn't have said that. Must it hurt to fall off a horse? If it was me, I would be scared

Luo Zhan's mood was depressed to the extreme, and his thin peach blossom eyes were red.

If that kind of pain How much pain should it be if that accident is enough to make a child blind?

He hated himself for not remembering. The pain in that memory was only borne by the tiny and fragile little girl in front of her, and he didn't even have the qualification to explain his identity to her.

Luo Zhan's silence disturbed Tang ran for a long time.

After some entanglement, the little girl finally got up the courage to open her mouth and comforted her inexperiently: "those things are over, Luo Luo. You're fine now, and you'll get better and better in the future... "

Luo Zhan looked at the girl's calm eyebrows and eyes. After a long time of silence, he whispered, "well. It will be better in the future. "

“……”

Tang ran looks hesitant.

She could hear that Luo Zhan's emotional state seemed to be very low. According to him, the way to stimulate the secretion of neural regulatory substances in his brain and then generate excitement

Tang hesitated for a long time and asked softly, "if I kiss your back, will you secrete a lot of that neurotransmitter and then mobilize your emotions?"

Luo Zhan was taken away from the low pressure mood by the girl's words.

Luo, the devil in his heart, had long been trampled under his feet by the angel Luo, who was full of remorse and guilt. He said helplessly, "it was a joke with you."

"Ah," sighed the little girl in disappointment, "I thought a kiss would stimulate the brain."

"In theory, it can." Luo Zhan said, "kissing belongs to sexual thorn A kind of stimulus. This kind of stimulation classification has a high efficiency and great influence on the neural regulatory substances of the brain, which can be achieved only by input in the visual aspect

For example, some members of the int team are deeply interested in a small filmLuo Zhan narrowed his eyes, and from the bottom of his heart, he screened 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 protective circle for her. At this time, she was looking up curiously: "then why did you just say no?"

Luo Zhan slightly drooped his eyes: "no, Luo Xiu and I are affected by the growth environment, and the threshold range of the stimulus required by external response is on the high side as a whole - just like the visual stimulation I said, we will not have any response."

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, will not have any effect on us --"

"

Luo Zhan was held by the girl's two hands. The back of the raised hand was very light and moistened.

Luo Zhan froze.

A few seconds later.

Tang ran feels the pulse under the finger tip that hasn't left yet, and looks up in a puzzled way:

"Luoluo, your heart rate is much faster."

Luo Zhan:
