In this way, the root knot does not seem to be in Professor Yan, but in fact, Professor Yan's madness is not a sudden mutation when he grows up, but has been there since he was a child.

She would hide alone in a dark room, quietly staring at the people in the light, her eyes dark and obscure, mature not like a child at all.

He would also run out in the middle of the night, rummaging through the dirt for all sorts of dead and unknown things, and bringing them home.

When she was older and had a certain amount of hands-on ability, she began to intensify her efforts and dissect all kinds of living creatures.

If it's just an autopsy, it can be regarded as her scientific research spirit. But Professor Yan obviously prefers the miserable screams of small animals when they are tortured to the process of dissection.

In order to increase the duration of this pleasure, she even taught herself all kinds of medical knowledge, trying her best to make those little animals live a little longer and scream a little more poignantly while dissecting.

Professor Yan's behavior and performance, her parents obviously can't accept it, after trying various educational methods and even taking medicine to see a psychiatrist to no avail, they gradually began to alienate this strange daughter, only to ensure her basic life, and no longer want to have a little communication with her.

Although she has a bad personality, Professor Yan's academic performance is just the opposite, in primary, middle and high schools, she basically did not fall out of the top five in all the exams she took, and she got various scholarships.

And after going to university, she restrained her behavior, began to focus on all kinds of knowledge, devoted herself to the ocean of science, and after graduating from the doctoral program, she married her current husband and gave birth to a daughter, that is, Xiaoxiao.

If such a life continues, with Professor Yan's smart brain, he will surely win various awards and become a famous scientist who has contributed to the world.

But when she tidied up her room and found the thin booklet, everything began to slide into the abyss of no return.

Professor Yan has fallen deeper and deeper into the unnatural world, and has become obsessed with the existence of ghosts to a certain level, so he often appears in hospital morgues, emergency rooms, and other places, just to observe the various manifestations of everyone before and after death.

However, she doesn't have yin and yang eyes, no matter how she looks at it, it's useless, even if the ghost floats past her, she won't have any reaction at all - this makes Professor Yan, who has been growing up since he was a child, and he will definitely be able to get whatever he wants with his own brain.

She began to go more and more insane, throwing tantrums at her own daughter whenever the research didn't go well, scolding her, beating her, and even abusing her.

The child she conceived and gave birth to in October seems to have become her exclusive venting tool, without any safety and freedom, no matter where she hides at home, she will be dragged out by her mother who returns home to beat and scold.

Until one day, Xiaoxiao suddenly found that her mother had regained the peace of mind that she had long ago every time she saw her.

It was Xiaoxiao's happiest day, and the mother and daughter really had a good time - and then, Xiaoxiao was killed.

Professor Yan took her to the balcony and bought her a lot of toys, and just as the little one was fiddling with the toys with great interest, Professor Yan gently reached out and pushed them.

"Smack!" Xiaoxiao fell off the balcony and died instantly.

Afterwards, Professor Yan cried and blamed himself: "It's all my fault, it's all my fault that I saw her playing with toys on the balcony and had too much fun, so I couldn't bear to call her back, who ......knows?"

Who can bear to blame a heartbroken mother? The saddest thing about losing her own child is her mother!

Only Professor Yan's husband remained silent about the whole thing, perhaps he had realized that the woman who had shared his bed with him for many years was actually a madman.

It is said that there is only a thin line between a genius and a madman, and this sentence is vividly displayed in Professor Yan.

She killed her own daughter, just because it was easier for her to get away with the guilt of doing it to this child, and it was easier for her to lie and deceive everyone, that's all.

As soon as Xiao Xiaoxiao fell off the balcony and broke away from the corpse, he was caught in the mirror by Professor Yan, who had prepared everything early—that time, it was also the first time in Professor Yan's life that he saw the existence of ghosts.

When she was ecstatic and eager to start researching immediately, this ability disappeared again.

No matter how hysterical Professor Yan is, there is no way to see another world again, and even because Xiaoxiao has died, she has no place to vent.

The depression accumulated more and more in his heart, and in the end, Professor Yan went completely crazy.

In the year since Xiaoxiao's death, she has killed several people one after another, but each time she has done it to the dying person in the hospital, so that no one has found it.

This is obviously not a long-term solution, and Professor Yan can only reluctantly stop after not seeing a ghost several times.

Just at this stall where research was stagnant and there was no way to enter, Tong Yan suddenly broke into her sight.

I don't know where she got her intuition, from the first time she saw Tong Yan talking to herself in the air around her, Professor Yan understood that this girl had something in her that she longed for the most, but couldn't get.

Since you are hungry, of course you have to get your hands on it.

"My mom said she had everything ready and was just waiting for the day of July and a half." Xiao Xiao finally said.

"Half of July...... Halloween? Bai Ruolian smiled, "Is it because the yin qi is the heaviest on this day, and the ghost door is wide open?" ”

Xiao Xiao shook her head, she was just a teenager, and she had been locked up at home without contact with the outside world, how could she have heard of Halloween, a holiday that few people talk about now.

Bai Ruolian turned around and beckoned to the office door: "Did you hear that?" This woman is about to succeed, guess she, after she obtains the Yin and Yang Eye, will she be the first to do it to you, the lewd ghost who has been dangling under her nose? ”

"Oh, I forgot." She suddenly laughed, "Have you ever been retaliated against for doing something to her?" Won't it ...... Your death is her handiwork, right? ”

With Bai Ruolian's voice, the frightened figure of the middle-aged man gradually appeared at the door of the office.

With his strength, he would definitely not be able to resist the mirror that Professor Yan placed outside the small building, and now he was able to enter the small building safely, but it was because Bai Ruolian attached a layer of spiritual power around his soul body, which was convenient to control him on the one hand, and could also bring him in on the other hand.

"You...... Who the hell are you! "What kind of person can become such a powerful being after death? The middle-aged ghost trembled his lips and muttered, "You and ...... That woman, it's not a good thing! ”
