According to the research of biologists, the generation of love is not as sacred, so beautiful and romantic, and so incredible as everyone imagines. In fact, it has a scientific mechanism and a scientific explanation.

When the other half of a person's life appears, her or his appearance, voice, smell, behavior, etc., stimulate the person's brain, secrete corresponding chemicals, and make people feel romantic, happy, happy, and relaxed, forming an early strong impulse.

That's love!

So scientists call these neurotransmitters and chemicals 'love hormones.' ’

Little.

There are many kinds of love hormones, and they appear at different stages of love, controlling the beginning of love, blazing, and then flat.

First of all, from love at first sight to falling in love, it is PEA, also known as phenylethylamine, that controls people in the body. PEA is a neurostimulant synthesized by the human body itself, which can make people feel extremely high, and with this substance, both parties in love will "call". This thing also has the effect of enhancing confidence and courage, making the lover confused and lose his mind, which is also known as the saying 'the IQ of men and women in love is zero'.

However, any substance has a 'lifespan'.

The peak concentration of PEA lasts from about 6 months to 4 years, with an average of less than 30 months. That is to say, under normal circumstances, a couple of men and women will gradually sober up and slowly lose their passion after two or three years of love.

The second love hormone is norepinephrine, which can make men and women in love feel their hearts beating.

Speaking human words is heartbeat.

The third love hormone is more familiar to everyone, it is dopamine, which mainly plays a role in transmitting messages of excitement and joy, which can affect the degree to which everyone feels the pleasure of things. The reason why people become addicted to some things is because they make them secrete more dopamine.

In the process of love, the sense of security and satisfaction brought by hugging, kissing, playing poker and other behaviors between men and women comes from the hormone dopamine.

The fourth love hormone is serotonin, also known as serotonin, which is a vasoconstrictor, which is related to the stupidity and denailing of the hot love stage, and is also related to male lust.

When the above main hormones disappear, it means that the love is over, love is facing a major test, and then the human body will secrete a love hormone called endorphins, which makes both lovers feel calm, restore reason, and calmly look at the feelings between the two parties. If enough endorphins are secreted after the end of the relationship, it is likely to lead to a long-lasting and stable relationship.

In addition, loyalty between lovers is important, and posterior pituitary hormone can make lovers feel a sense of responsibility and mission, and make a psychological commitment. In general, the more hormones secreted by the posterior pituitary gland, the more loyal the lover becomes, a veritable 'loyalty hormone'!

Seeing this, do you think it's subversive for those who have girlfriends or boyfriends, and don't you really want to refute it, bullshit love hormones, scorching, she's my woman...... Ahem, it should be 'I love her (him) from the bottom of my heart, and it has nothing to do with love hormones'.

In fact, it doesn't matter whether you admit it or not, people's emotional mechanisms are very complex and delicate, and it is difficult to tell whether love is produced by love hormones or whether it comes from the heart.

I love her, she loves me, enough is enough.

In the last catastrophe, human beings created immortal gods, but love was still not studied clearly, and later the Pangu tribe abandoned love in order to avoid the troubles caused by love, and required everyone who ascended to the eternal kingdom to give up love in order to be reborn and immortal.

In their view, love has the power to destroy the world, and it always brings war, pain, and tears.

But in the eyes of the generals, love is the greatest power of zombies, and he can use this power to protect Nuwa and fight for love.

And Xu Cheng, he wants to use this power to stimulate the divine source, break the bloodline limit, and upgrade to the fourth generation of gray eyes.

Of course, love hormones are not necessarily equal to true love, and the specific effect is not clear.

"Open the love hormone transmission channel."

"Ready to inject love hormones!"

The small square in the thermal chamber opened, and a thin metal tube of needles extended out, and the sharp needles pierced into Xu Cheng's skin, injecting 400 μg of mixed love hormones into his body.

"400μg of love hormone infusion."

"Retract the transmission channel."

Outside the core cabin, Lianfeng, Rena and other technicians paid close attention to the curves, values and monitoring images on various instruments and equipment, and they were surprised to find that after the injection of love hormones, the energy in Xu Cheng's body was very 'calm', like a smooth straight line, without any ups and downs, incredibly calm, terrifyingly calm.

Lian Feng couldn't help but ask, "Xu Cheng, how are you?" ”

The space in the thermal chamber seemed to tremble slightly, and in response to her was a terrifying, domineering, and long roar, which conveyed an incomparable sense of shock, and everyone's heartbeat seemed to slow down.

"The energy in his body is increasing rapidly, almost geometrically." Rena, who was the first to react, exclaimed.

Lianfeng hurriedly shouted: "Xu Cheng, what's wrong, answer!" ”

The roar disappeared, Xu Yingtong knelt on the ground, his fists clenched, rattling, his head hung down, his body trembled slightly, he clenched his teeth, and felt that every flesh and bone in his body was filled with the sudden expansion of divine power, constantly torn apart, and then reorganized.

Pain!

The pain was so terrible that he couldn't respond to the mercy.

"Xu Cheng, answer me......"

The voice of the wind came into his ears from all directions, and it was as beautiful as a fairy sound in a trance, as if it contained the magic power to soothe the pain, making Xu Cheng feel an indescribable pleasure and ripple while bearing the pain.

Not good!

The divine source in Xu Cheng's body belongs to the original divine source, and it has only been half a month since it was born, and it has not fully adapted to the new body. To Shen Yuan, many things in Xu Yin's body are completely unfamiliar, including love hormones.

The love hormone originally had a great stimulating effect on the divine source, and the sensitivity of the original divine source was ten times or even dozens of times that of the inherited divine source.

Under this kind of stimulation, the divine source was overloaded, the divine power was rushing, the divine sea was roaring, and Xu Cheng felt that his body was about to explode, full of power.

"Promise ......"

"Shut up!" He roared in pain, "No...... Regardless of gender...... If you don't want to...... I'm in love with you...... All...... Don't even speak. ”

Hearing this, Qi Qi outside the thermal cabin breathed a sigh of relief, but then fell into an indescribably strange atmosphere.

Rena asked ignorantly, "What did he mean by that sentence just now, and why did he fall in love with him when he spoke?" ”

Lian Feng turned a deaf ear and said in an unquestioning tone: "Xu Cheng, report your status, I need to know your current situation." ”

"Blood ......"

Lianfeng hesitated slightly, and ordered: "Open the blood transmission channel." ”

As soon as the blood vessel appeared, Xu Cheng jumped out, grabbed it, and drank blood. In the blink of an eye, he drank 50 liters of blood, which was almost equivalent to the entire amount of blood in the bodies of ten people.

The technicians looked at Xu Cheng on the surveillance screen in horror, and the Adam's apple rolled subconsciously.

Drinking nearly 100 liters of blood in a row, Xu Cheng suddenly let go of the blood vessel, shook out three or four steps like drunk, turned around suddenly, two zombie teeth broke out of his lips, and a dark and weird magic pattern appeared on his face, and he opened his mouth and roared, and the extremely violent energy mixed with the fierce aura surged out, like countless heavy hammers smashing the four walls of the thermal cabin, rumbling.

There was a dead silence in the entire factory, only Xu Cheng's domineering and terrifying roar echoed.
