Chapter 49

Tang Ran lowered her head silently.

After a few seconds of quiet on the stairs, Luo Zhan heard the little girl say in a low voice: "You lied to me."

Luo Zhan: "It's true that I didn't lie to you."

"You are just lying to me, how could you have this kind of thing?" the little girl stuttered in anger, "An unscientific folk remedy?"

Luo Zhan was amused by the little girl's expression of seriously discussing academic issues and couldn't help laughing, but he still tried to hold back: "The science you are talking about is medical science, and my folk remedy also has science, but what you are talking about is not the same subject."

Tang Ran hesitated for a few seconds, but still couldn't help but seeking knowledge. He looked up and asked suspiciously: "Then what discipline are you talking about?"

Young Master Luo laughed lazily and began to talk nonsense: "Psychology."

"ah?"

"Psychologically, being kissed can stimulate the brain to produce pleasant emotions, which will help the sensory system ignore pain to a certain extent."

“…”

Tang Ran fell into deep thought when he heard this.

Although she questioned the reliability of this folk remedy, what Luo Zhan said sounded very reasonable.

Luo Zhan looked at the little girl's thoughtful look and made her think a little heavier: "Why, don't you believe what I said?"

Luo Zhan said as he stepped down two stairs and stood next to the handrail of Tang Ran's next stairs. He turned sideways and blocked the empty space behind Tang Ran with the wooden escalator fence to prevent the little girl from falling down.

Then Luo Zhan laughed lazyly: "I don't believe anything, 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 darkness was quiet for a few seconds, and then a low and pleasant smile sounded.

Tang Ran was confused: "Why are you laughing at?"

"Because this is a very good..." Luo Zhan paused, "Academic issues."

Tang Ran pursed her lips and refused to speak.

She felt that Luo Zhan was not praising her problems, but more like mocking her.

Luo Zhan saw that the little girl was a little annoyed by herself, so he had to cough and suppress her inappropriate teasing. After thinking for a few seconds, he said: "There are some neuromodulatory substances in the brain that will affect people's emotions. Kissing only affects the secretion of these neuromodules, and other behaviors can also achieve the same effect."

Tang Ran: "Neuromodulation?"

Luo Zhan patiently explained to the little girl: "Well. For example, some kind of neuromodulatory substance that promotes excitation. When the brain is subjected to a certain external stimulus, it can enhance myocardial contraction force, thereby increasing cardiac blood flow, accelerate blood flow throughout the body, stimulate the follow-up reaction of systems at all levels, and finally..."

Luo Zhan raised his hand and gently tapped the girl's forehead, "It will tell you that you are in an excited state of rapid heartbeat, rapid breathing, even wet palms, and fever."

Tang Ran always has an endless desire for knowledge in unfamiliar fields that she has never been exposed to. Few people would chat with her, and would not patiently explain to her those curious questions like Luo Zhan.

So when Luo Zhan spoke, she seemed to have forgotten all the unhappiness in front of her and listened to him.

After listening, Tang Ran asked curiously: "Do you have this state?"

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

"Because, you seem to know it very well."

"I won't."

"Hmm?" Tang Ran was confused, "Why?"

“…”

Luo Zhan thought about it and lowered his eyes lazily and smiled: "It's probably because of the Luo family's inheritance? Luo Xiu and I have not experienced this emotional stage. This hormone is stimulated and secreted, which requires our reaction to the outside world to reach a certain threshold - you can understand that our growth environment makes us reach a sufficient threshold lower limit much higher than others, and it is difficult to get enough stimulation - the external stimulation that will make most people blush and heartbeat reaction is not enough for us, so it is difficult for us to feel excited."

Tang Ran thought about it, nodded and shook his head, and carefully corrected it: "Everyone said that Luo Xiu has a gentle personality, so he doesn't like you..." The little girl stopped at this point.

However, it's too late.

Luo Zhan narrowed his eyes lightly, held the handrail of the stairs and asked dangerously, "What's wrong with me, little girl?"

Tang Ran lowered his head and showed a serious expression that he would never speak.

Luo Zhan raised his hand angrily and amusedly, rubbing her long hair: "I'm not gentle to you? I'll give you all my gentleness alone, little ungrateful."

“…”

Tang Ran still pursed her lips and didn't say anything, but her cheeks under her long hair were slowly showing a little bit of a shiny look.

She counted her heartbeat that had been chaotic for a few beats, felt the slight hot flash in her palm, and was a little novel and jumped out of the way-

Is this what Luo Zhan said about the reaction of the brain under external stimulation?

That feeling really seems pretty good.

Luo Zhan lowered his hand and said, "But don't be fooled by Luo Xiu. It's harder for him to give emotional feedback to external stimuli than me - that person can only look gentle and gentle. According to his indifference, he is probably at the level of an iceberg that has become a spirit."

Tang Ran was stunned and raised her face: "Why is this happening?"

Luo Zhan's eyes were cold.

After a moment, he sneered: "The Luo family'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. This will completely abstain from the dependence mentality of childhood, and use this stage to develop the child's intelligence in the fluctuation period to the maximum through professional training."

Tang Ran was so angry that he stayed in place: "But this doesn't seem like raising a child."

Luo Zhan lowered his eyes and laughed: "Yes, does it look like raising a Gu?"

“…”

Tang Ran didn't know the meaning of raising a Gu, but she felt that it was not a good word.

Luo Zhan didn't know what he thought of, but his eyes suddenly stopped when he turned dark.

A few seconds later, he lowered his eyes slightly and whispered: "Originally, I would probably have the same personality as Luo Xiu, but I am still lucky than him."

Tang Ran asked curiously: "Why?"

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

Those eyes used to be beautiful.

Luo Zhan's body twitched in pain, which made him frown involuntarily. But he still looked at the girl's eyes as if he was self-abuse and refused to look away.

"Because something happened when I was 11."

Tang Ran suddenly realized: "Is it because you went to learn how to fall down on a horse and get seriously injured and fall into a coma for a long time?"

“…”

Tang Ran frowned and said, "If I were Grandpa Luo, then I would only hope that you would live well and would not care about you."

"..." Luo Zhan clenched his fists slightly.

Tang Ran didn't notice it. After thinking about it, she bent down the corner of her eyes and smiled: "But you can be considered a blessing in disguise, right? Luo Luo? Then Grandpa Luo will definitely indulge you in the future, so you will have the same personality as the rumor. That's great--"

"not good."

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

Tang Ran was stunned, her smile disappeared, and she looked up uneasily - it was the tone that interrupted her so fiercely, and it seemed that the cold and unwillingness was suppressed inside.

This is the first time Tang Ran has felt such a terrible negative emotion in Luo Zhan.

Then she heard the man gritting his teeth and repeat: "Not good at all."

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

Luo Zhan raised his eyes, struggling with the entangled and painful emotions in his eyes. After a while, he said hoarsely: "Tang Ran, I don't want such a blessing in disguise, I don't want it to die."

“…”

Tang Ran was silent. After a few seconds, she slowly lowered her head: "I'm sorry, I shouldn't have said that. It must be painful to fall from the moment I got off? If it were me, I would be very scared."

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

If that kind of pain is... that enough accident that makes a child blind, how painful should it be? He hated that he still can't remember it. 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 qualification to explain her identity to him.

Luo Zhan's silence made Tang Ran uneasy for a long time.

After some confusion, the little girl finally plucked up the courage to speak and comforted her unskilledly: "Those things have passed, Luo Luo. You are good now, and you will get better and better in the future..."

Luo Zhan looked at the girl's calm eyebrows and after a long quiet time, he whispered: "Well. I will get better in the future."

“…”

Tang Ran showed a hesitant expression.

She could hear that Luo Zhan's emotional state seemed to be very depressed. According to him, the method that can stimulate and secrete the neuromodulating substances in his brain and then produce 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 motivate your emotions?"

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

The demon Luo in his heart had long been stepped on under his feet by the angel Luo who was full of self-blame and guilt. He said helplessly: "That's a joke on you."

"Ah," the little girl sighed disappointed, "I really thought that kissing her can stimulate the brain."

"It is indeed possible in theory." Luo Zhan said, "Kissing is a sexual sting... a type of stimulation. This stimulation classification has a high effect on brain neuromodulatory substances and has a great impact. It can often be achieved by only visual input.
