City’s Best Divine Doctor

Ye Qiu didn’t care much about George’s illness. After dinner, he was ready to drive himself to the ancient castle.

He didn’t bring Ma Wenwen and Louise. As he got into the Range Rover, Ye Qiu drove again to that ancient castle.

Maybe there was no party tonight.

Or maybe it only happens once every while.

Now, the ancient castle felt eerily silent.

Especially after Ye Qiu turned off the car lights and engine, he realized that outside the castle, apart from the sound of the wind, there was no other sound at all.

Also, it’s the deep winter now; even though it wasn’t snowing, the temperature here felt very low.

Ye Qiu sat in the car for a while.

He got out of the car and walked towards the ancient castle.

The large door of the castle was closed, appearing no different from those relics.

The door was closed, but Ye Qiu pushed it gently, and it opened.

Upon entering, he found that besides some dim yellow lights, there were no other lights.

Ye Qiu continued to walk inside.

He paused, noticing a peculiar scent.

It was the smell of blood.

He followed that metallic scent and found it was coming from the basement of the castle.

Some ancient castles have basements, and there’s a stairway leading down; stepping on that stairway would make a noticeable sound.

Ye Qiu neither turned on the lights nor made a sound, cautiously descending the stairs.

It took about five minutes.

When Ye Qiu stopped, he had reached the basement.

In the basement, Ye Qiu saw in the corner, similarly dim yellow lights were on, and then Ye Qiu saw patches of already coagulated blood.

What kind of place is this?

Ye Qiu really didn’t know, but he didn’t stop; he continued to examine the place and found it very eerie, with vampire traces in many locations.

Could this be the vampire’s lair?

Ye Qiu found it strange.

Where did those vampires go?

Could they possibly turn into bats?

Speaking of spells, Ye Qiu did believe in them.

But, a vampire turning into a bat?

Ye Qiu didn’t believe it.

The reason people associate vampires with bats is precisely because both are bloodsuckers.

When Ye Qiu came out of the basement and went upstairs to the place where last night’s party was held, now it was eerily quiet, completely devoid of last night’s bustling splendor.

What shocked Ye Qiu even more was seeing that the decorations on the castle walls were completely different from last night.

Last night it looked at least luxurious, but now only the remnants of history remain, with many walls covered with moss and a lot of bat droppings inside, appearing very disgusting.

Now, to Ye Qiu, what he saw last night was likely all an illusion.

This could even deceive him.

Like that disgusting big cake, which was filled with wriggling maggot-like things; he saw through that, but what he didn’t expect was that the environment here was all fake too.

So-called illusion.

According to scientific explanation, an illusion refers to perceptual experiences that appear without corresponding objective stimuli. In other words, an illusion is a subjective experience whose sensation resembles perception.

This is a rather serious perceptual disorder.

The difference between illusion and delusion is that the former lacks objective stimuli. Its vividness can evoke emotions or behavioral responses like anger, sadness, fear, avoidance, or even aggression.

Trying to persuade someone experiencing illusions not to believe them is sometimes futile.

Illusions can occasionally be seen in normal people. For example, auditory or visual hallucinations may occur when half-asleep, known as pre-sleep illusions; illusions occurring upon waking while sleepily are known as post-sleep illusions.

Illusions can also be induced by suggestion. As documented in past literature, some people immersed in religious fervor claimed to see "Guanyin Bodhisattva" or "Jesus Christ," without necessarily having pathological implications.

However, it should be mentioned that most illusions are pathological. If a person experiences illusions repeatedly, they should be promptly checked to diagnose psychological disorders and prevent incidents like harming others, running away, or committing suicide under the influence of illusions.

Ye Qiu indeed encountered illusions.

This couldn’t possibly be just a simple party on the surface.

Like some wealthy scions hallucinating if they inhale something, but the illusion Ye Qiu felt is completely different.

Illusions can be classified by their origin into true illusions and pseudo-illusions.

True illusions, also known as complete illusions or perceptive illusions, refer to experiences perceived via sensory organs that are actually nonexistent, originating from the objective space, possessing "real," vivid and lively illusions. Patients firmly believe in them, accompanied by corresponding thought, emotion, and volitional behavior responses.

Pseudo-illusions, the illusion imagery isn’t vivid or lively, arising from the patient’s subjective space, like within the brain, the body.

Illusions aren’t perceived through sense organs but can be "heard" internally, like a speaking voice inside the belly, or "seen" without using one’s eyes like there’s a person’s image in the brain.

Although illusion imagery differs from normal perception, patients often strongly believe they indeed heard or saw, hence firmly believe it.

Illusions arise from many causes, including central nervous system disease, emotional influence, suggestion, impaired vision and hearing, sensory deprivation, etc.

Any factor increasing the burden on sensory analyzers or enhancing their activity can prompt illusion.

Mountain climbers ascending peaks higher than several thousand meters may develop illusions due to lack of sensory stimuli.

After cataract surgery removal in elderly people, illusions frequently occur, possibly due to sensory deprivation combined with mild age-related brain changes.

Those with impaired vision and hearing may experience delusions and illusions due to difficulty differentiating sensory analyzers.

Hence, hearing-impaired individuals often have paranoid mental disorders.

Illusions caused by organic brain disease have been clinically and experimentally confirmed many times.

Illusions can appear in states like high fever, epilepsy, and other diseases.

They can also arise in abnormal psychological states, where patients abandon objective, real concepts to react with self-based psychological states, treating them as external stimulus characteristics.

Some experts believe the brain needs a minimum level of environmental stimuli; if this minimum is unmet, or disturbed by psychological disorder factors, it may prompt the brain to reconstruct reality and the environment’s significance based on past experiences and personality traits, resulting in illusion.

This theory holds everyone possesses the ability to produce illusions, but in usual circumstances, these are continually tested by the brain via interactions with sensory-based real stimuli, thereby inhibiting such abilities.

Also, some drugs can cause illusions, but these aren’t genuine illusions; they differ from self-produced ones and are merely results of these drugs’ effects on the brain.

Yet some think illusions are abnormal dream extensions occurring during non-sleep states. In certain situations, including dreaming, imagination disassociates from self, with a person unaware they’re fantasizing.

"Imagination" retrieves data from sensory memory, reconstructs it, and sends it back to the sensation area to form illusion. Dream-imagination aims to replace real signals with simulated sensory signals, driving the autonomic nerve for mind/body function.

The essence of illusion has been extensively debated. As blindness and deafness can still produce illusions, illusions aren’t peripherical receptor disorder. B.X. believes "illusion is the excitement of the sensory central unrelated to external impressions."

Popov argues illusions are caused by inhibition processes.

He notes illusions intensify during sleep or waking, lessen with caffeine, strengthen with bromide, and indeed, illusions are easily observed in intermediate states between sleep and wakefulness.

These two opinions should be considered supplementary, as modern studies on central inhibition prove not all central nervous neurons are in a state of inhibition during sleep; some neurons remain moderately excited.

Therefore, illusion may be due to certain levels and scopes of cortical excitement under conditions inducing central inhibition.

As illusion emergence is a whole-brain reaction, attempts to anatomically localize illusion in the nervous system are incorrect.

The problem is, Ye Qiu found that the illusion he perceived last night isn’t quite the same concept as these so-called illusions.
