That short story collection only kept Zheng Rui going for more than an hour, because she had read most of the articles in it online. At this time, the rescue had not yet come, and there was not even the sound of cars running on the road outside.

She panicked again.

—so she opened the notebook and found a small piece of paper in the first page.

Zheng Rui was sure that she had not clipped it herself, because the piece of paper had a few lines written on it in a font similar to that of a black font.

[Gender: Female]

[Height: 170.3]

[Type: Immortal; Rapid recovery, resurrection after faking death from serious injuries】

This is...... What the?

The first two lines refer to her, but what is "immortal"? Recover quickly, and can you fake your death and resurrect? Is this really Earth Online?

It is very stupid to believe a small piece of paper, but since there is such a strange incident as the flattening of the surface building, Zheng Rui is still a little curious and scratches the back of his finger with the utility knife in the commissary. The utility knife was sharp, and even if it was cut very shallowly, a string of blood suddenly oozed out, but when she wiped the blood off with the absorbent paper in the paper drawer, the scratch was completely gone.

Crouch...... Trough?

Is this true?

That......

Try going deeper?

——

Soon, through an act of death called "practice", Zheng Rui realized that the so-called "immortal type" mentioned on this piece of paper was most likely true.

Her first reaction was that she had been captured and transformed by the aliens, but that didn't explain why the aliens had bothered to do so, and they were so kind enough to leave her a note to remind her.

According to Occam's razor principle, "don't add entities unless necessary", first of all, eliminate the brain in the jar. Now that it is assumed that an entity has flattened the building where she lives and transformed her, the technological gap between this entity and her, an ordinary member of human civilization, is so great that it is assumed that she is likely unable to understand neither the technology used nor the intentions of the other person. That being the case, it was pointless to speculate on an entity that was far beyond her comprehension.

Mainly, this trait is more interesting in comparison to the apparently "immortal" type.

When I was in high school, my Chinese teacher once gave an essay topic called "If there are only three days left to live". At that time, most people were talking about how to cherish life, but one of the classmates who left the deepest impression on Zheng Rui was about how to experience various suicide methods in three days in 800 words - because according to the title, he will not die within three days.

It's a brilliant idea, but it's just a fictional essay topic (and most people wouldn't want to trade the rest of their lives for only three days of suicide experience). But now that she's able to fake her dead and come back to life, it means that she can experiment with near-death experiences in the true sense of the word.

Of course, this belongs to the category of human experiments, which needs to be reported, audited, etc., and should be done in a formal sterile positive pressure laboratory. But Zheng Rui knew that if she waited until the school had completed a series of procedures for application and approval, the experimental project would belong to someone else, and it would definitely be impossible for her to arrange it herself. And seriously, it's not necessarily that the school is still there. Nearly 60 years of silos have disappeared out of thin air, and it is definitely not possible to do things according to the rules and procedures.

Therefore, she thought that if she hadn't come to the rescue tomorrow, she could try it herself first—a "pre-experiment" anyway.

——

So this "pre-experiment" was "pre-tested" for four days.

The last cut of the carotid artery and blood loss to death was quite effective, and the NDE (Near Death Experience) felt really good, and it was even a little addictive.

But until now, no rescue has come, which makes Zheng Rui feel that the whole world has forgotten her. However, she is "immortal", and the lack of systematic research on her acquired special ability is a real loss for all mankind.

However, Zheng Rui thought that maybe she was not the only immortal type. And since there is such a thing as "type", there must be other types besides the immortal type. No matter what happens, the structure of modern society dictates that as long as key resources are not the only one, the bigwigs who control various other resources will always be able to produce results one step faster than ordinary people. Maybe the academic bigwigs have already studied the immortal type and other types now, and she is still amusing herself with two sentences to break the experimental record.

Alas, it's a little sad to think about it. But scientific research is like this, it is inevitable to encounter the situation of hitting the topic, but everyone's research has its own characteristics, in fact, this kind of repetition is not completely meaningless. Besides, even if the content she does is exactly the same as that of the big guys, then it can be considered exploratory learning, right? After all, she is a weak scumbag in her senior year, and she still has to focus on studying at this stage.

Putting away the experiment notebook, Zheng Rui grabbed her blood-soaked hair and walked to the cut water pipe to wash it. The water pressure is much lower now than it was when it first broke, but it looks like it's still adequate. In the past four days, she has also tried to drink tap water, because tap water is wasted when it is not used, and the drinks in the commissary are fine.

She has not come to the rescue for four days, so she has a basic judgment that I am afraid that at least the surface buildings equivalent to the whole city have been flattened, so the rescue may have to wait for a long time, and she must be prepared to survive in the short term under the existing conditions. Fortunately, she was not in the city center when she was "Earth Online Refresh", but lived in her grandparents' house, otherwise she would have faced all kinds of smashing and robbing.

Of course, Zheng Rui was also worried that it was not that the rescue did not come, but that the rescue came at night when she was asleep, and did not find her. That's why she wakes up every morning to look at the neighborhood across the street, and when she sees someone coming out of their basement, she goes back to her basement with confidence. She won't take the initiative to communicate with the people opposite, because she knows that the basement of the new community opposite is the dormitory of the community security guard, and it is estimated that there will not be much inventory in it.

Although if the person on the other side is really short of food and water, she will also divide the things in the commissary, but Zheng Rui is not idle enough to take the initiative to deliver things to others. And the other party should know that there is a commissary here, if the people on the other side do not take the initiative to find her, it means that life can still be passed, and she doesn't need to worry too much about others.

After washing her hair, Zheng Rui drank tap water for a while. According to the law of conservation of energy, the blood she loses is the mass she loses, and it is impossible to make up for it even by the recovery ability of the immortal type - usually people do not come up with macroscopic hypotheses that contradict the laws of thermodynamics - so it is necessary to replenish the plasma first by drinking water. However, according to the definition of this immortal type, she should produce blood cells much faster than normal people, and her tolerance to hypoxia is also greater, and she can still exercise normally when she loses 30%~40% of her blood, she feels that she is really a miracle of biology.

Oh no, to say "miracle", the whole thing is unbelievably strange.
