Xiang Kun tried everything he could eat and drink at home.

Then make a record on the document:

solid food: instant noodles x, potato chips x, oatmeal biscuits x, Oreo biscuits X;

liquid drinks: boiled water √, pure water √, pure milk x, Red Bull X;

thinking that he had eaten porridge in a small shop outside on July 14, and all of them vomited, so he added:

clear porridge x into the solid food, Fried bean sprouts x, mustard X.

After checking and recording himself, he looked at the time at 1:30 in the morning, so he washed and prepared to go to bed first to ensure good sleep and rest.

But after lying in bed for nearly an hour, Xiang Kun did not feel sleepy. He thought that maybe he had just slept for 20 hours before, so he didn't feel sleepy, so he turned up and reopened his laptop.

Previously, he used his body changes as a keyword search, most of the search results are pointing to "vampire.".

So Xiang Kun is going to take "vampire" as the target to collect some information.

Of course, literary works such as twilight, night visit to vampires and Vampire Diaries won't be the targets of his collection.

He also saw the question "what's the experience of becoming a vampire?" besides the answers of those vampire novels which are obviously open-minded, there are also some answers that collect data seriously to explore the origin and scientific explanation of vampires.

Most of the answers about the origin and scientific explanation of vampires are similar. They think that the origin of vampire legend is Eastern Europe and central Europe in the 18th century.

Those who become "vampires" are usually people who die of accidents or violent diseases.

Their relatives either suffered from a bad disease or suffered other accidents and died one after another. And a few days before they die, they dream that dead people turn into vampires to suck their own blood.

In the final analysis, when there is a disaster or an infectious disease, or other unfortunate events, they will be recorded on the deceased family members.

At that time, the way to deal with it was to dig out the heart of the corpse and burn it. In a short period of time, the body's flatulence gave out strange sounds, and the tissue contracted, which made the nail look like it grew after death, which further promoted the legend of "vampire".

Later, with the development of medicine, various phenomena have been explained, and "vampire" has become more and more literary and artistic, has been added more images and characteristics, and even has super ability and immortal body.

Sometimes, patients with rabies, pica, porphyria and other diseases will also be used as the scientific explanation of modern "vampire".

Xiang Kun also went to watch the vampire analysis program "vampire forensics" specially produced by National Geographic Channel, which also talked about almost those things, and there was nothing that could explain his series of changes.

However, some descriptions and descriptions in some unreliable literary works are more consistent with his situation.

Unknowingly, it was dawn, and Xiang Kun was still in good spirits, so he decided to go out and buy something back.

I went to the bathroom to wash my face, opened my mouth and checked it. I found that my teeth had almost grown. At least when I grinned, other people thought his teeth were white, and they should not see anything.

To his relief, his new teeth were normal, and there were no terrifying fangs.

After Xiang Kun went out, he bought several kinds of food, such as fried dough sticks, soybean milk, pancakes, bread, and so on. He only tried to eat each of them, and tried the same, but there was no exception. Finally, he vomited out.

But eat less, nausea, vomiting when the discomfort, will also reduce a lot.

Xiang Kun hitchhiked to the shopping mall to buy some things, including a variety of food and drinks, an induction cooker and a matching small pot, cleaning tools, weight meter, meter ruler, etc.

When I went home, it was more than 10 o'clock in the morning, the sun was very big, and Xiangkun subconsciously avoided the sun.

It was hot in July, but Xiang Kun didn't feel the heat at all. He went out to buy things, crowded the bus, carried several bags and estimated the weight of things weighing dozens of Jin. He didn't sweat much.

Although the body instinct seems to subconsciously avoid the sun, but after noticing this, Xiang Kun deliberately stood in the sun, let the sun directly.

But in his feeling, standing in the sun did not have obvious discomfort, even the normal should feel the burning sensation of being exposed to the sun.

He looked up at the sky again, blinded by the sun, but the same for ordinary people?

Although he did not understand the specific reasons, he could still feel the body's instinctive rejection of the sun and the sun.

According to the information he read last night, "vampires" are much more photophobic. Once exposed to the sun, their skin will quickly burn and become black.

The so-called "vampire" porphyria, when exposed to the sun, will appear photosensitive dermatitis, pruritus, varicella can symptoms.

In contrast, although his body instinctively wants to avoid light, he has no obvious symptoms or reactions in the sun, and is even more heat-resistant than before?Back home, Xiang Kun directly moved a chair to the bathroom and began to drink.

Drink a coke, more than 20 seconds later, vomiting.

Drink a sprite, more than 20 seconds later, vomiting.

Take a sip of orange juice and spit after more than 20 seconds.

……

However, after drinking the coffee made by Nestle gold medal freeze-dried coffee powder, Xiang Kun did not spit it out for a few minutes, which made him vaguely find a way. Because he had drunk Nestle's three plus one instant coffee before, he also vomited in more than 20 seconds. What is the difference between the two? What's the difference from the drinks you've been drinking?

Xiang Kun made boiled eggs again and ate them, but there was no reaction. Then boiled beef slices with water, eat also no problem.

So he began to think, is it because of the sugar content of food?

Although black coffee, eggs and beef also contain trace amounts of sugar, compared with other foods and drinks, it can be said that it is much lower.

But why sugar? Xiang Kun learned that most of the energy needed by human body is provided by sugar.

When Xiang Kun was recording in front of his laptop, he suddenly felt a convulsion in his stomach and rushed to the bathroom again. He vomited up. All the things he had eaten and thought there was nothing wrong with him also vomited.

Xiang Kun reluctantly wiped his mouth, washed his face, and went back to the computer, and made a note in the document: food or drink with low sugar content can stay in the stomach for a longer time, but after 20 minutes to half an hour, it will still vomit out.

Then he began to take off his clothes. With only one pair of boxer shorts left, he stood on the electronic scale he bought to weigh himself. He measured his chest circumference, waist circumference, arm circumference and other data with a meter ruler, and set up his mobile phone to set up a delayed photo to take a full-length picture of himself.

He's going to start recording his physical changes.
