Lu Ming's question was somewhat unexpected by Zhang Dingshan and the others.

Is there anything to question about this question?

It is impossible for Master Zhiguang to lie to Master Zhitong, and it is almost impossible for Master Zhitong to lie to himself. Before Master Zhiguang died, he really saw what "Great Fear of Heavenly Demons".

Zheng Peng's screams before he died were also presented in front of people through the surveillance screen. If Lu Ming is willing, he can take out that video and replay it hundreds of times.

This matter is almost certain and unquestionable.

"I don't think there's anything to discuss."

He Wei shook her head first.

Lu Ming said, "First of all, I agree that they did see the Great Heavenly Fear Demon before they died, and I also think that there is nothing to discuss and question. It's just that, based on the principle of "different interpretations of the same clue" that I established earlier, we can also try to interpret it a little bit."

"How do you interpret it?"

"First of all, it can be determined that both Master Zhiguang and Zheng Peng felt extreme fear at that time. And because they all claim to have seen the Great Heavenly Fear Demon, so if we let it be, we will think that it was this Great Heavenly Fear Demon that brought the ultimate fear and scared Zheng Peng to death, and Master Zhiguang was scared to collapse and commit suicide.

But is that really the case?"

"What else could it be if it wasn't?"

This seems to be a very simple logical relationship, so simple that it does not need to be thought about further.

Lu Ming pondered for a moment and said slowly: "Some research data show that under extreme fear, even the fear of dying, people will hallucinate, and it is possible that the more afraid you are, the more hallucinations will appear."

At this moment, He Wei, who was still a little absent-minded, sat up straight in an instant. Zhang Dingshan raised his eyes slightly and looked straight at Lu Ming.

This is a very simple phenomenon of psychological suggestion. Although Lu Ming is not proficient in psychology, he also knows this.

For example, when people are surrounded by darkness and in a state of fear, the more afraid people are of ghosts, and when they look into the darkness, the more they seem to see shadowy ghosts.

But if one is not afraid at all and looks into the darkness, he will not see ghosts.

"I mean, is it the advent of the Great Fear of Heaven and Demon that brought the ultimate fear, or is it the extreme fear that caused the hallucination that led to the sight of the Great Fear of Heaven and Demon? Which of the two comes first and which comes last?"

"That's not right."

Lu Qingliang suddenly said, "If Master Zhiguang's heart is the most fearful, it is the Great Fear Heavenly Demon that he hates the most, but Zheng Peng also saw the Great Fear Heavenly Demon, how to explain it?"

He Wei said in a deep voice, "I mentioned to Uncle Zheng about Master Zhiguang. He knew that Master Zhiguang was frightened and collapsed by the Great Heavenly Demon."

Lu Qingliang was thoughtful.

If you explain it this way, it becomes "Zheng Peng received a psychological hint about the Great Fear of Heavenly Demons in advance, and in the extreme fear before death, the psychological hints came true, and the hallucinations appeared Great Fear of Heavenly Demons."

Zhang Dingshan muttered, "If this is the case, then a new problem must be explained. Where does the victim's fear before death come from?"

If this fear wasn't brought about by the Great Fear of Heavenly Demons, then there must be a source, right?

He Wei thought about it and said, "Perhaps...... Well, I vaguely remember that our human brain is divided into different functional regions, and stimulating different areas can bring different emotions."

It's like a drug. Drugs produce a large number of related hormones to stimulate the corresponding brain areas, which can produce a huge amount of pleasure when people have done nothing else.

"It's a possibility." Lu Ming nodded: "This fear actually has no source, it's just because the victim's brain, amygdala or related brain regions, uh, I don't know much about this, in short, the area in charge of fear has been strongly stimulated, and as a result, the victim feels the ultimate fear out of thin air." And because of the extreme fear, I hallucinated, and I saw what I feared the most in my heart."

Zhang Dingshan looked at Lu Qingliang: "You immediately go to the relevant experts to consult, see if there is such a possibility." And, again, is there a difference between being frightened by an external object and causing fear, and being stimulated to a relevant area of the brain and causing fear? Can you tell the difference?"

Lu Qingliang immediately said, "I happen to know an expert in brain function research, so I'll go and ask him."

"Okay."

In the video screen, Lu Qingliang's figure disappeared. But it was only half an hour before he reappeared.

"How?"

Lu Qingliang said: "Experts say that there is indeed such a possibility. For example, the use of bioelectricity to stimulate relevant brain regions, or certain chemicals, such as L-dopa, the metabolic precursor of dopamine, which produces dopamine under the action of aromatic amino acid decarboxylase, can make people perceive certain emotions for no reason.

And whether it is due to the stimulation of bioelectricity or the fear caused by the sight of the terrifying scene of the outside world, there is no difference between the two situations for the body. Because the root cause is stimulation of the autonomic nervous system, which dominates fear, the two cannot be distinguished.

Well, long-term use, or being affected by such means, can affect human physiology and cause certain changes, such as the inability of the body to synthesize dopamine, but obviously, this does not apply to our current situation."

There are good and bad news.

The good thing is that this proves that Lu Ming's speculation is possible, at least theoretically. The bad thing is that even if Lu Ming's speculation is true, it is impossible to distinguish between the remains of those victims.

No one knows if the fear they are feeling is actually seeing a terrifying external object or because the autonomic nervous system has been stimulated. Because there is no difference in the performance of the two in the body.

Lu Ming pondered for a moment, but still cheered up: "Now, for the time being, let's continue to push down according to our inference. Let's assume that the victims in the Marina Building were scared to death because the relevant brain areas were stimulated, then what is the possible way for them to be stimulated?"

First of all, bioelectricity can be ruled out. Because when Zheng Peng was victimized, he had extremely complete and comprehensive testing equipment by his side. If Lou Shen had stimulated his brain with bioelectricity, it would have been impossible to hide from the device's monitoring.

"Maybe there's another way, psychological suggestion. Well...... It can't be."

He Wei proposed an idea, but she rejected it.

The reason is equally simple. If there was some kind of existence at that time that gave Zheng Peng the ultimate sense of fear by means of psychological suggestion, it would also not be able to escape the monitoring of the monitoring equipment.

Several options were discussed, but in any case, there was no ability to bypass the monitoring equipment.

Of course, it can also be assumed that the "Lou Shen" has mastered some means beyond the current level of human technology, but in this way, the discussion at this moment is meaningless. At the same time, the need to introduce this assumption is not seen at this stage. This possibility was thus temporarily ruled out.

After that, there is only one possibility left in front of people.

Chemical substances.

Chemicals similar to L-dopa. After this substance enters the human body, it is either directly stimulated, or the metabolites after entering the human body can stimulate the relevant brain tissue, or the autonomic nervous system, so that the human body can produce related emotions.

"Qingliang, let's ask the relevant experts again, is there such a substance, after being absorbed by the human body, it can strongly stimulate the autonomic nerves or tissues in charge of fear, making people extremely afraid, and even directly scaring people to death?"

"Okay."

Lu Qingliang left again. Came back again shortly after.

"According to experts, fear arises because the brain function area analyzes and determines that there is a threat, which activates the function of the amygdala, which in turn triggers the body's emergency response. But so far, no chemical has been found to directly irritate the amygdala and cause it to cause fear."

"Haven't found it yet? Do experts mean that the existence of such a substance has not been theoretically ruled out?"

"It can be understood that way."

Lu Qingliang nodded.

"Okay, then let's assume that such a substance exists." Lu Ming said: "Then we can think about how this substance, under the premise of having such a comprehensive monitoring equipment, entered Zheng Peng's body and produced its effects?"

"It should be air."

"Possibly. Do you still have air samples collected by air monitoring equipment at that time?"

"Yes."

He Wei replied, "There are about five liters left, divided into ten air cylinders."

Lu Ming nodded: "In addition to air, there is also a possibility that it is absorbed through the skin."

At that time, Zheng Peng was not wearing a full-body protective suit. He must have been in contact with the environment and air inside the Marina Building at that time. In this way, the possibility of dermal absorption after contact cannot be ruled out.

"In that case, let's try to see if this unknown chemical we speculate exists. Qingliang, I would like to trouble you to go to the relevant experts and conduct some tests on the air samples collected at that time, as well as Zheng Peng's body, to see if you can find the residue of this chemical."

"Okay."

promised, and Lu Qingliang was leaving. But at this time, Lu Ming stopped him again.

"Don't go yet."

After pondering for a moment, Lu Ming said slowly, "Don't tell the experts the truth, don't tell the experts that we are not sure whether this kind of thing exists. You can say this to the experts, just say it...... We have established that this substance exists and that it is up to the experts to do just to find it out. Also, find several groups of experts to do it at the same time."
