After Li Qian finished telling me the story, she handed me a diary and an envelope, she said that the diary was left by Zhang Chi before his death, and after reading it, she would have a better understanding of him.

The envelope contained 1,000 yuan, and when I was optimistic about Zhang Tong, she would give me another 1,000, she wanted to give me more, but the efficiency of her state-owned enterprise was not very good, and the mother and son lived in poverty, so they could only give so much.

I laughed and said that money is a small thing, but being optimistic about children is a big thing. Li Qian then said that the child would yell if she woke up at night and couldn't see her, so she had to hurry over to accompany Zhang Tong before he woke up, and then left quietly.

I sat on the couch and counted some money, just a thousand yuan, and I put it in my pocket. I don't really love money very much, but in just one year after graduation, I really realized what it means to be poor and short-minded.

Yu Nan, my girlfriend in college, because of my excellent grades in college, I was handsome, I loved me and loved me to death, how many times I fell in love to the depths of my life, I said that I would not marry in this life, but as soon as I graduated, I saw that I didn't find a job, so he broke up with me immediately.

I briefly reminisced about the past, and then began to study the journal. I have to say that in today's fast-paced society, there are not many people who are willing to insist on keeping a diary, which is really a very commendable move.

In order to understand Zhang Chi in more detail, I read his diary one after another, from May 1 last year to January 1 this year, fortunately, he doesn't write every day, otherwise I don't have to sleep this night.

The diary has not been updated from January 2nd to March 9th, and I guess this period should be the stage when Zhang Chi knew that his wife was cheating and was struggling with his thoughts, because his thoughts were more chaotic during the period, so he didn't continue to write.

The diary began to be re-recorded on March 10th. I was still a little sleepy before, but after reading this article on March 10th, I immediately fell asleep, and the content of the diary is as follows:

"I'm struggling today about whether or not to tell the rabbit the truth. All along, I and the little wolf, and the rabbit live in this land is very safe, very happy, but today the little wolf told me that there is a tiger on this land, it wants to destroy our lives, I and the little wolf are nothing, you can fight with it, but I don't want it to hurt the rabbit, the little rabbit is so cute, so simple, no, can't tell the rabbit, never, the little wolf and I have to swear to protect it......"

I didn't fully understand the contents of the diary at first, but simply made a guess that the little rabbit mentioned in the diary should refer to his son Zhang Tong, "I" should refer to Zhang Chi himself, and the tiger should refer to the man who cheated on Li Qian. In this way, the little wolf should refer to Li Qian, but this is a bit unreasonable, Li Qian belongs to the kind of easy-going personality, and it really doesn't make sense to describe it as a little wolf.

I then continued to look back:

"On March 23, the little wolf and I have been fighting the tiger in secret, but it is too strong, the little wolf and I are not its opponents at all, the little wolf was seriously injured in a fight, and died this morning, before dying, it repeatedly told me that I must protect the rabbit and not let it suffer even the slightest injury, rest assured little wolf, I will not let the tiger succeed."

Seeing this, I couldn't help but chuckle in my heart, it turned out that the little wolf was not referring to Li Qian, but a set of personalities that he had separated, and I hurriedly continued to look down:

"March 30th, today is the saddest day of my life, despite my hard work, the little rabbit was still killed by the tiger, I am sorry for the little rabbit, and I am sorry for the dead little wolf, but you can rest assured, I will not let the tiger get this land, I will destroy this land, and the tiger will die together!"

This is the last entry in the diary, Li Qian said that Zhang Chi committed suicide by jumping off the building in early April, it seems that Zhang Chi mentioned in the diary and the tiger died together, which means ending his life, so to speak, Zhang Chi actually split into four personalities, in addition to himself, there are little wolves, little rabbits and tigers.

This is really a bit unbelievable, but what puzzles me is that the tiger's personality is in, could it be a personality invasion?

When I was suddenly in college, there was a senior who wrote his graduation thesis about personality invasion, and he wrote in his thesis that when a person communicates a lot with another person who has no personality at all, the other personality is like an alien species invading a new ecological environment, because there are no natural enemies, so it can quickly occupy it in a short period of time.

The paper caused quite a stir at the time, and my psychology supervisor openly criticized the student in a public class, saying that personality invasion was pure nonsense and completely impossible.

But this situation, if it is not explained by personality invasion, is really a bit inexplicable.

I kept imagining the story told in Zhang Chi's diary in my head, and before I knew it, I fell asleep on the sofa, and I don't know how long later, I suddenly heard an extremely violent and piercing scream, which frightened me into a thriller and bounced off the sofa, and then I heard a child's cry. This should be what Li Qian told me before, Zhang Tong had a convulsion in his sleep.

I tiptoed to the door of the bedroom where they slept, put my ear to the door and listened to the movement inside, Li Qian kept comforting Zhang Tong who woke up from his sleep at this time, Zhang Tong cried and shouted: "I was wrong, Dad, don't beat me, ah......"

The crying is very heart-wrenching to listen to. The crying continued for a while, and then it gradually subsided, and then it was as quiet as death, and both mother and son were probably asleep again, and I was just about to leave, when suddenly I heard movement again, so I hurriedly put my ear to the door again, and this time I heard the sound of a woman sobbing.

Hearing Li Qian's cry, I began to understand why she had to let me live, every day facing a child who could get sick at any time, she was both heartbroken and scared, but what made her even more painful was that all of this was caused by herself.

Cheating is immoral, but she has also endured too much, if she was the only one in the room, I would definitely go in and comfort her, and there is no major that will comfort people more than someone who studies psychology.

I leaned in the doorway and listened for a moment, then slowly moved to the couch. Although Li Qian had prepared a special bedroom for me to rest, Zhang Tong had just fallen asleep, and the person with a split personality had a nervous breakdown, and the two bedrooms were next to each other, so I was really afraid of waking up the child when I opened the door.

Lying on the couch again, I couldn't sleep. Zhang Tong's sudden awakening triggered my thinking, Zhang Tong at normal times, his personality is like his mother, melancholy, and introverted.

The reason why he suffers from split personality is due to the high frequency of domestic violence by his father after his illness, and among Zhang Chi's multiple personalities, the one with a serious tendency to violence should be the tiger, if the appearance of the tiger's personality is really the so-called personality invasion, then Zhang Tong's split personality should also belong to personality invasion.

But this is more difficult, because in the realm of personality invasion, I belong to a blank slate. I thought, get through the evening, and wait until dawn to reach out to my college classmates to see if I can get the contact information of the senior who wrote the personality invasion essay from them.

At this time, I glanced at my watch, it was already more than three o'clock in the morning, and if I didn't sleep, it was about to dawn, so I lay on the sofa and began to close my eyes, ready to use the next time to sleep beautifully, I just felt a little sleepy, and suddenly there was a scream, but after this scream, it was not a cry, but a scream one after another.

I immediately tiptoed to the door of their bedroom, this time I could hear more clearly, only to hear Zhang Tong scolding inside: "You rabbit cub, I must kill you today, see if you die, I'll go over and discount your legs now, let you run around again, kill you, I must kill you......"

Just listening to the sound, it's hard for you to believe that this is a 7-year-old boy, I thought that Zhang Tong inside was tired of scolding, and would continue to lie down and sleep, but suddenly I heard a crisp sound, followed by a woman's wail, I heard that something was wrong, and immediately pushed open the door and rushed in.
