On the second night of that incident, Qian Lang had a high fever and talked nonsense. The local local doctor said that he was overly frightened, so he gave him some good medicine to calm his nerves and reduce his fever.

A few days later, Qian Lang's illness slowly improved. But that incident has since become a psychological shadow that he can't erase in his life.

"I see." Zhang Fan thought for a while and asked, "Do you suspect that the black shadow we saw before is the same thing as the one in that cave?" ”

Qian Lang nodded.

"What the hell is that?" Zhang Fan asked puzzled.

"The people in the village and I also want to know what that harmful black shadow is. It's a pity ......" Qian Lang sighed regretfully.

"I know what that is!" Leng Xingyun turned on the flashlight and walked over from afar: "Tell you to stay where you are, why are you so disobedient?" What to run around? It's easy to find me! ”

"Stop!" Zhang Fan and Qian Lang shouted at the same time: "Are you real or fake? ”

"If I were a fake, you would be dead!" Leng Nebula was loud and silent, and walked towards them quickly.

"Strange." Zhang Fan wondered: "This time the voice is so loud, why is there no longer an echo?" ”

Qian Lang didn't care, but as if he had seen a dear God, he greeted him, half laughing and half crying: "You can come back!" If you don't come back, Zhang Fan and I won't be scared to death, we will have to burp! ”

Leng Xingyun walked up to Qian Lang and didn't stop, but he thought that Qian Lang was in the way, so he pushed him away and walked straight to Zhang Fan.

"Disobedient again and again, is it too long? Or do you think your parents raised you too easily, and you can quickly replicate the same you when you die? "Leng Xingyun is really angry this time.

Zhang Fan lowered his head like a child being trained: "I'm sorry, it's not that we don't listen to you because we have a long life, but ......"

Zhang Fan and Qian Lang complemented each other about what happened since Leng Xingyun left, and elaborated in detail.

"If you can do it, and turn a blind eye to that thing, it won't attract you anymore." Leng Xingyun sighed: "Fortunately, I found you in time, and fortunately, you haven't had an accident yet." ”

"Leng Xingyun, you just said, do you know what that thing is?" Qian Lang asked.

"Hmm." Leng Xingyun explained: "At first, I didn't think about it; But then I remembered that I had seen it once. In ancient times, it was called the 'Earthbound Spirit'. To put it in modern theory, it is a special energy body.

Originally, he was also a human being, and he died tragically with extreme resentment before his death, but this was burned alive by the flames. Just because, before death, the brain waves are abnormally active, even far exceeding the normal human brain wave frequency, which happens to collide and absorb with the frequency emitted by a special magnetic field energy.

After death, brain waves are present with special magnetic field energy. Gradually, there is a form but no substance, a shadow. And that special magnetic field energy gives the shadow some energy.

It becomes no wisdom, only the residual resentment in the brain waves of life, relying on special magnetic field energy to take revenge without any purpose. That is, to kill at will. ”

"Isn't that the ghost of the legend?" Zhang Fan asked.

"It's not." Leng Xingyun replied firmly: "In this world, there are no ghosts!" There are only some things that, with the current level of science, cannot be explored for the time being. But as far as I know, thirty years ago, there was an experiment.

Connect the brain waves of a dying person who is obsessed with it to a meteorite with a powerful special magnetic field energy. At the moment when the person died, although the physical body died, the mental power, that is, the human brain waves, was very active.

Then, under the repeated stinging of the meteorite, the person's brain waves gradually merged with the special magnetic field, forming a faint shadow of human nature.

In the end, the researchers destroyed all the shadows and all the experimental data in order to keep them secret and not to cause panic in the society. ”

"So, the black shadow we met was actually just the brainwave of a person who died tragically here, absorbing a special energy magnetic field and mutating into a black shadow?"

Seeing Leng Xingyun nodding, Zhang Fan asked again: "Didn't you say that the black shadow has no entity?" What's the red line on the cave wall? ”

"I drew it with a marker."

Leng Xingyun's statement, the two didn't believe it, especially Qian Lang.

Qian Lang explained the incident when he was a child to Leng Xingyun, and finally asked: "If this red line is really drawn by you, how can it be so long?" Moreover, in the cave I went to when I was a child, there was also a red line when the black shadow appeared, but it was not there before it appeared. What's going on? ”

Leng Xingyun's expression was obviously unnatural: "It's not important, as long as I'm here, that mutated thing won't dare to come." ”

Although the two still didn't believe it, they didn't ask any more questions.

After looking at each other for a while, Zhang Fan asked Leng Xingyun, "Why have you been there for so long?" Nothing happened, right? ”

"It's fine." Leng Xingyun replied lightly: "It's just that in the process of exploring the path, I got lost." As soon as I find my way back, I will go back to pick you up.

But I found that you were no longer where you were, and that I had left no mark, and that I was like a headless fly, looking for you everywhere. During this period, he also encountered the black shadow, and after being attracted by it and repeating the route back and forth, he remembered that it was the Earth Bound Spirit.

Since, its brain waves are controlled here by a special magnetic field energy, it cannot be separated from the cave. So, as long as I ignore his existence, I won't go down the same route. ”

"I see." Zhang Fan said: "Then let's stop here and return quickly." ”

Then, the two began to return with the markers drawn by Leng Xingyun.

But both of them found a problem, Leng Xingyun made a mark with a bold red marker stroke of a pentagram, while the previous cave wall was an irregular two red thin lines.

This proves that the feelings of the two are right, Leng Xingyun lied about this matter, at least to hide it.

But the two didn't intend to expose it, because they knew that with Leng Nebula, they didn't have to be too afraid of those strange things.

Trust him, and it will be solved.

In fact, Leng Nebula did tell them a white lie. That black shadow was actually scared away by Leng Nebula's poisonous blood......

On the way back, although the black shadow reappeared, but this time there was a cold nebula, and the black shadow only dared to climb the cave wall not far away.

As a result, two thin red lines were left on the cave wall.

After walking for an unknown amount of time, the three of them finally returned to the cave where they had been.

At this time, the blizzard outside the cave had stopped, and nearly one-third of the cave entrance had been sealed by the blizzard.

But the three of them didn't bother to bother with that for the time being, and when they returned to the warm tent, they soon fell asleep.

However, before falling asleep, Zhang Fan promised in his heart that he would never be so curious in the future! ……
