Sure enough, the female doctor said it, Xiao Nan woke up the next morning, and found that as long as she moved a little, her whole body hurt like a knife, especially the right half of her body, the chest, shoulders, back, and arms were more serious, and the muscles of her limbs were as if they were sore and swollen like chicken blood, but she couldn't exert a little strength, and she really became a helpless little sister, if she didn't help her get dressed and comb her hair before going to work, I really didn't know how to go out to meet people.

Just cleaned up for a while, the female doctor came to see Xiao Nan, as soon as she entered the door, she simply asked her a few words, and immediately took her to the medical school for a more detailed test, Xiao Nan heard that her heart was furious, because she had fantasized countless times that after the secret of her "transformation" was exposed, she was arrested by a secret scientific research unit for slice research or something, it was not too scary!

However, the female doctor told Xiao Nan that she had tested the blood sample drawn out last night in the factory infirmary this morning, and found that there were abnormal metabolites in her blood, and she felt very wrong.

Although Xiao Nan still had some resistance in her heart, she was weak and weak after doing it with others several times before, and she also found that there might be some problems with her body, and she was a little worried that if she had some terminal illness, she wouldn't live long. Although she is not afraid of death, as a person who has faced life and death, she understands the preciousness of life better than others, she is not willing to die casually, even if she is destined to die, or at least, knowing how long she can live, she can make her last life more meaningful - after thinking about it again, Xiao Nan still agreed.

So Xiao Nan obediently followed the female doctor and went to the medical school to find her sister. In the laboratory of the Institute of Biology of the medical school, the female doctor gave Xiao Nan a myofibroblast biopsy and puncture sampling, and after local numbness was drunk, she used a long probe to pierce the deltoid muscle group of her shoulder, and saw that such a thick and long needle slowly pierced into her body, Xiao Nan couldn't help but beat a drum in her heart, fortunately, the whole process was completed very quickly and in less than a minute, and then the female doctor helped her get dressed, gave her two slow-release capsules that could reduce muscle pain for her to take, and took her to the rest room inside for bed rest.

Perhaps because the fatigue of the body was not fully relieved, although Xiao Nan didn't like the strange smell of the surrounding laboratory, she fell asleep not long after her head hit the pillow, and by the time the female doctor came back to wake her up, it was already noon.

As soon as Xiao Nan opened her eyes and saw the female doctor, she hurriedly struggled to get up from the bed, and the swelling pain that affected the muscles of her whole body when she got up made her grit her teeth and gasp. "How's the lab result?" she asked, frowning, holding back the pain.

The female doctor didn't answer immediately, but looked at her with a very strange look, as if she was looking at a specimen of rare birds and beasts in a museum, and Xiao Nan's heart was furious, and she suddenly remembered the blood test slip that her mother had mailed her, but unfortunately she was soaked in the rain and couldn't see what kind of results were written on it...... Could it be that she had already seen some secret from the tests?

"Little sister, sister wants to ask you a few questions...... "The female doctor moved a chair and sat next to the cot. "I hope you answer me truthfully, otherwise I won't be able to help you~"

What do you mean? Xiao Nan's eyelids jumped. Could it be ...... Can she tell from the lab results that I am a boy? or ...... I have a very terminal illness, and although I am nervous, my face is still calm: "You...... What questions would you like to ask me?"

Seeing that Xiao Nan's expression had obviously become a lie, the female doctor smiled slightly and comforted her: "Little sister, don't worry too much, in fact, your situation is not a big deal, you are just a little special compared to ordinary people......"

When the female doctor said this, Xiao Nan was even more panicked, her heart thumped as if she was about to jump out of her chest, and she hurriedly pressed her heart with her hand, but her face, which was already as white as jade, became even paler. "It's okay, you can ask......" The voice was weak, but it was quite in line with her current image.

"I've got a general idea of what happened last night, and I've heard that you knocked down four strong men in a cornfield with your bare hands, is it true?" the female doctor's expression was quite curious, and it was obvious that she still didn't believe it.

Xiao Nan nodded and said, "It's true, I'm hiding in the cornfield, it's dark, they can't see me, I'm actually plotting ......"

"That's ......" The female doctor's expression seemed to be slightly disappointed, and she asked again, "But then you covered everyone's escape, and you faced seven men by yourself and knocked them all down?"

"How is it possible, I'm not superhuman...... Xiao Nan explained helplessly: "I just took advantage of the chaos to knock down two people, and then got into the cornfield, at first they wanted to come in and arrest me, and I stabbed one with a hairpin, and then no one dared to come, just stood outside and threw bricks inside, so I took advantage of the chaos to escape." ”

"I see...... the female doctor nodded, thoughtful. "That'...... Have you ever noticed that at some point you are going to be special...... I mean, you can jump higher, run faster, and punch more than the average person at certain times......"

Xiao Nan found that the female doctor's question did not mention the secret of her "transformation", and her nervousness gradually relaxed. "Yes, sometimes, huh...... For example, when I feel very anxious and dangerous, I will suddenly exert incredible strength, but then I will become weak and weak, and I will even faint...... But there has never been a time when the consequences have been so severe......"

"I see, it doesn't seem that the sample is contaminated, but that your physique is a little different from that of ordinary people. The female doctor took out a color print from her pocket and handed it to Xiao Nan, who took it and saw that there were some strange oblong objects on it, which looked like a capsule.

"This ...... What is it?" Xiao Nan pinched the printer paper in his hand and looked confused.

"It's the mitochondria, and it's responsible for the energy that feeds the human body, and with that energy, we are able to do all kinds of movements. Mitochondria are common in each of our bodies, because our body cells contain countless mitochondria. The female doctor pointed to the capsule in the picture and said to Xiao Nan: "It's just that you are different from ordinary people...... This is a picture that was taken under an electron microscope just now, and in your sample of deltoid fibroblasts, the number of mitochondria is much more than that of a normal person, and you know what that means?"

Xiao Nan looked at the female doctor blankly, shook her head, and vaguely felt in her heart that it was definitely not a good thing.

"With such a large number of mitochondria, if they work together to provide energy to your body, you will gain a lot of strength beyond ordinary people, very powerful power......" The female doctor's expression at this time was simply a little fascinating.

Xiao Nan was stunned by her, and asked weakly, "Yes...... How powerful?"

"Uh......" The female doctor rolled her eyes: "Actually, I don't know, it takes a lot of effort to calculate it accurately, and you need to collect more live somatic cell specimens in your body...... But it's not necessary, you just need to know that you have far more power than ordinary people. But ......"

Xiao Nan's heart skipped a beat when she heard the "but", and she didn't know why, as if she knew in advance that there would be a "but" waiting for her. "But...... What?"

The female doctor's expression became serious: "But what I have to tell you is that if a normal person has such a large number of mitochondria, there is usually a side effect - making your metabolism much faster than ordinary people, in other words, you will eat more than others, but you will be hungry faster than others, and what's worse is that you will age much faster than ordinary people......"

After speaking, he looked at Xiao Nan with some sympathy, for such a young young girl, aging faster than others is definitely bad news that cannot be more terrible, enough to make some fragile girls have a mental breakdown.

However, Xiao Nan looked at the female doctor blankly, and said for a long time: "That's it?"

You're not afraid that you'll become an aunt in your twenties......? Is it a slow reaction or is the Shen Sutra relatively big? The female doctor was choked by Xiao Nan's reaction, she originally planned to scare Xiao Nan with this bad news, who made Lao Zuo value her so much?

Seeing that her "conspiracy" did not succeed, the female doctor rolled her eyes very unwillingly, and continued to say with a straight face: "But you don't have to worry too much, because I found that there are two types of these mitochondria, one is always active, and the other is usually dormant and does not participate in energy metabolism at all, which means that you are usually no different from ordinary girls, and they will only be activated under special circumstances...... I tried activating them with several human hormones and found that the dormant mitochondria had a somewhat weak response to thyroxine, and when I switched to epinephrine, they were all activated in a very short time as the dose was increased......"

The female doctor was talking like a golden flower, and suddenly noticed that Xiao Nan was looking at her blankly, as if she was listening to a book. "Doctor, I don't understand what you're talking about......

The female doctor couldn't help but cover her face with shame, feeling that she had told the stone everything. "Okay, okay...... I put it another way to understand, although you have a lot of mitochondria in your body, most of them are usually resting, so you will not eat too much because of too fast metabolism or premature aging, only when you encounter an emergency, when the brain secretes a large amount of adrenaline, those dormant mitochondria will be activated and return to work, which is the secret of your sudden great strength. ”

"Oh......" Xiao Nan nodded, this time she finally understood. "Then why did I ......"

The female doctor interrupted her words with a wave of her hand, and her expression became serious: "Don't be in a hurry to listen to what I say, this is very important to you! When I gave you a physical examination yesterday, I found that as a girl, your body is indeed very strong, but no matter what, you are still a little girl, with your current body condition, you can't bear the strength you have, and your current skeletal muscle strain is proof of this!" If you use this power regularly in the future, sooner or later it will cause irreversible and serious consequences to your body organs, and then it will be more than just muscle pain...... Do you understand what I said?"
