Xiang Yun solved the problem and left the hospital.

Yangzhou No. 9 Hospital is not a good place to stay.

Wang Goudan was babbling and complaining about being knocked unconscious and kidnapped.

It didn't know anything about what had just happened, which made Liu Yan'er wonder very much.

Liu Yan'er couldn't help but ask: "Some powerful Yin Spirits can also temporarily possess the human body, I heard that the Taoist master of the Immortal Realm can also use the power of seizing the soul out of the body, but why can the dark nightmare not only possess it, but also affect other people through the possessed person?"

How can this be explained?

Xiang Yun got some information from the Book of Heaven.

Dark Nightmares have a lot of origins, but they're complicated to explain.

Therefore, Xiang Yun summarized the ideas and roughly introduced some features.

"First, the Dark Nightmare is not a Yin Spirit, but a native creature. ”

"Second, the Dark Nightmare is not possessed but parasitic, it is very fragile and does not have any supernatural powers when it is separated from its host. ”

"Thirdly, the Dark Nightmare is not a great threat to ordinary people who do not cultivate, and only creatures with cultivation will attract the parasitism of the Dark Nightmare. ”

"In the process of parasitism, the dark nightmare will merge with the host's soul, and the host's spirit will be used as a medium, and the host's cultivation will be used as a bridge to release the host's tainted soul power. Soul power is invisible and intangible, more elusive than mental power, so it is usually difficult for us to feel it. ”

"I see!" Liu Yan'er clapped her high-fives, "These soul powers that have been tainted by the Dark Nightmare will erode other people's souls, so people who have come into contact with the host will also become crazy." ”

Xiang Yun said: "Not only that, these nightmares-polluted soul power accumulate in the bodies of other monks or demon beasts, and when they reach a certain level, there is a certain probability that new nightmares will be born." ”

Liu Yan'er showed a shocked expression.

Is this how creatures like Dark Nightmares reproduce?

In other words, a strong enough Dark Nightmare can infinitely generate new Dark Nightmares, and when the newborn Dark Nightmare grows, it can generate a new generation of Nightmares.

If this cycle repeats endlessly, wouldn't it be more terrible than any infectious disease, more deadly than any plague? It is enough to completely destroy a country, a population, and even an entire ecological chain!

Smoke guesses, though, isn't accurate.

But it's pretty much the same!

The origin of the Dark Nightmare is not simple.

Xiang Yun believed that this was not a creature of this world.

However, the Dark Nightmare, while terrifying, is not completely invincible.

Generally speaking, only a monk who has cultivated high enough will generate a new nightmare in his body, and if his cultivation is relatively weak, the contaminated soul power enters the body, and before it reaches the level of giving birth to a nightmare, it will completely collapse and go berserk and die, unable to become a new source of infection.

Liu Yan'er asked again: "If we hadn't saved this old man, what would have been his final result?"

"Well, once the parasitic time is too long, the host's spiritual power and soul power are exhausted, and the Dark Nightmare will not be able to continue to release its soul power, but at this time, it will completely occupy the host's body, making it demonize from the inside out, turning into a monster called the Nightmare Demon, which is a very powerful and difficult existence to deal with. ”

Xiang Yun looked at the girl beside him who seemed to be curious about the baby, "Is there anything else you want to ask?"

"Ah Yun, you are really so knowledgeable, my family is full of guys who think they have read more than 10,000 books, but they are far from you!" Liu Yan'er looked adoring, "I still have another question, why is Wang Goudan's cultivation obviously higher than ours, but he can't last longer?"

"People are born with spirits, and in addition, the soul structure of the three souls and seven spirits is more complex, so the ability to resist the dark nightmare is relatively strong, and the soul structure of the vast majority of demon beasts is relatively simple, so the resistance to soul erosion is weaker, plus the spirit of demon beasts is not innate, and it is easier to be stimulated to beast nature. ”

If Wang Goudan stays by the side of the mad old man for two hours.

One hundred percent of it will give birth to a new dark nightmare.

At that time, Wang Goudan will fall into a complete madness, and others can't even catch it.

When Wang Goudan heard these words, he not only didn't have any fear, but also said very proudly: "Hey, it seems that there is a powerful demonic beast hidden in Ben Wang's body, now who dares to look down on our demon dog." ”

Huskies don't seem to be saved!

Xiang Yun said goodbye to Liu Yan'er and returned to his home.

He always felt that after refining the dark nightmare of the mad old man in Yangzhou Ninth Hospital, there seemed to be an extra power in his body, although this power was not very powerful, it was obviously something he did not have before.

The Supreme Respect Hitomi can indeed recover the energy that has been refined by the life of the Overlord.

These recovered energies cannot increase cultivation and strength, but they can improve physique and bloodline.

But the question is, how should this power be used? He walked into the yard and looked around, when he suddenly noticed a rat coming out of the corner, sneakily looking for something.

"You're out of luck!"

"Let's do an experiment with you!"

Xiang Yun condensed the nightmare soul power fused into the Overlord's holy blood into his eyes.

Suddenly, my eyes felt a little numb, as if an electric current was flowing on them.

Xiang Yun released this power in one go, the power of the nightmare was invisible, and it would not produce the slightest fluctuation, but the speed was indeed very fast, and it instantly hit the sneaky rat in the grass.

The rat reacted immediately.

Its fur suddenly stood up.

His eyes turned blood-red and he immediately fell into madness.

It found Xiang Yun, it was originally afraid of humans, but it didn't seem to have the slightest fear at the moment, and immediately squeaked and rushed over, but was directly kicked away by Xiang Yun.

This is just an ordinary mouse, even if it is a casual kick from Xiang Yun, it is enough to kill it.

The rat did not die, and when it fell to the ground, its fur cracked open and was blown by flesh, and its size began to grow, and its body showed obvious alienation.

There is a tendency to demonize?

It shouldn't be directly demonized, right?

Xiang Yun had just had this thought.

With a bang, the mouse's fragile body exploded, turning directly into broken flesh.

No matter how tenacious the vitality is, it is impossible to resurrect it.

Why did it explode on the spot? Can't withstand some kind of alienation?

"Whew!" The husky spirit heard the voice and ran over, and when he saw this scene, he immediately said with disdain: "Boss, I didn't expect you to be this kind of person, actually bullying weak animals, it's really undisciplined!"

Xiang Yun glared at him: "You came over just in time, you sniff this mouse, is there anything abnormal?" ”

The husky spirit sniffed, "Hey, I smell a very special aura of power, neither demonic nor demonic, Ben Wang has never encountered it." ”

Xiang Yun thought for a moment, as if he was in thought.

The power of nightmares should belong to the variant of soul power, it can make creatures crazy, and at the same time can enhance creatures, it is indeed a very special power, and it has not been studied by human monks at present.

This discovery is enough to write several papers.

However, Xiang Yun obviously has no way to announce it.

Unless he wants to expose his secrets as well.

Xiang Yun could feel that after releasing the power of the nightmare, the power did not disappear completely, it seemed to recover slowly with time, but the power of the nightmare on Xiang Yun's body was very weak, and it was estimated that it was a threat to the little mouse, and it was not enough to deal with the monk.

It seems that there are still many things that can be excavated in his physique and bloodline.

In the evening, Hua Lei called, and the crazy old man had woken up.

After the examination of Yangzhou Ninth Hospital this time, his mental state has stabilized, and there is no difference between him and a normal person, which has to be said to be a miracle.

Xiang Yun asked Hua Lei to arrange for him to meet him.
