"The general meaning of the case is basically the same as the case you reproduced in front of me, right?" Xu Tian asked.

"Of course it is the same, but I didn't tell Lao Chen the story behind this case." Yu Yi said.

"If I'm not mistaken, the old man watching the play is the object of your suspicion, right?" Xu Tian asked.

"Except for the old grandmother, I really can't think that anyone else will be a murderer, when I told Lao Chen about this case, I revealed something about the old grandmother pretending to be demented, but I think that although the old grandmother has a motive to kill, she has no power to kill!" Yu Yi said.

"How do you explain the old lady who appeared in the woods? Teacher Jin and I thought we had hit a ghost. Xu Tian asked.

"The things in the forest are really exaggerated, I wanted to see you as soon as possible, so I did the things in the forest, and the corpse I asked you to keep is actually your talisman." Yu Yi said.

"I don't understand what you mean, how can a corpse become a talisman? Who the hell is that corpse? Xu Tian asked.

"That body is involved in another case, it has nothing to do with the case here three years ago, and I will tell you about that case after we have successfully boarded the rescue ship in two hours." Yu Yi said.

"So, when you were in the forest, you deliberately rescued me and Teacher Jin, could it be that someone was not good for us when we were in the forest?" Xu Tian asked.

"You can understand it this way, I really wanted to meet you soon, but it was because I was too anxious that I prompted you to enter the abandoned building in advance, for this matter, I have full responsibility, about this matter, I will also tell you in detail after we get on the ship." Yu Yi said.

"Oh well! Tell me more about the background of the old woman in the village. Xu Tian said.

"The background of the grandmother you learned before is actually true, but the story is not finished yet. There is indeed a middle-aged man surnamed Ma in this village, Lao Ma and I have a good relationship, and the first friend I met after coming to this island was Lao Ma. When the developer approached them three years ago, Lao Ma was the first to sign the demolition clause, and now Lao Ma should take care of his grandmother in the interior! Yu Yi said.

"What's the story of that old woman?" Xu Tian asked.

"Things have to start from the time of the crime, you also know before, the first person to die in the ancestral hall was an unmarried young man, the young man who was killed had no enemies in the village, he was also very warm, and he had many friends, whether it was old, middle-aged or young or children, and his relationship was very good, and he could be described as a good old man. But such a good man died on the stage in the backyard of the ancestral hall, and this incident caused a stir in the village at that time, and even the town police who came to handle the case felt incredible. You've been to an old house in the woods, and you should have read the clues in the old house, right? Yu Yi said.

"I already have a rough idea of what happened in this village before, but I think there are too many inconsistencies in the old house about intermarriage in the village, and there is no convincing force." Xu Tian said.

"Those clues were deliberately left by me, of course they are not true, in fact, the real clues I have ......" Speaking of this, Yu Yi began to hesitate.

"It seems that this case has a very strong impact on you, does it involve a deep human relationship?" Xu Tian asked.

"You can say that, but I don't like to understand this case with negative and dark thoughts, I prefer to look at this case with a sunny mind." Yu Yi said.

"No matter what, this case has had a more or less psychological impact on you, and you, as a partner of the police, really shouldn't leave false clues in the old house, and I really can't understand what you're doing." Xu Tian said.

"Don't talk to me like Xiao Ai, you people haven't experienced this incident, and you haven't heard me tell me completely, so you start judging me, it's very wrong for you to do this." Yu Yi said.

"Time is running out, another ten minutes have passed." Xu Tian looked at his phone and said.

"Alright! I'll tell you the truth about my grandmother right now. Yu Yi said with a long sigh. Grandma's experience makes me feel very incredible, since the grandmother returned to her hometown to care for the elderly, there are a lot of letters sent to the grandmother from the mainland, these letters were read by the grandmother alone, the old horse because of the busy work, but also rarely pay attention to the grandmother's life, but this does not mean that the old horse is not filial, you should be able to understand, right? There are many people who are busy running around for the life of the family, they are not unfilial, they are really in love, Lao Ma is such a person, he thinks that the grandmother is taken to live in his hometown, and it is filial piety to take care of the grandmother, in fact, the old horse is concerned about his business in the inland all the time. This was also the trigger for the mistake of the old woman, who had become very depressed since she returned to her hometown, and only when she opened the letters from the interior would the old woman laugh out loud from the bottom of her heart, and I had been in contact with her since I landed on the island four years ago, and I can say that I know the old man's mood better than the old horse. Yu Yi said.

"I believe that you must be very observant." Xu Tian said.

"But I've never seen my grandmother reply to a letter, although my grandmother's mind was not too clear at that time, and there were many times when my grandmother was very confused, but even so, my grandmother should have the idea of replying, right?" Yu Yi said.

"This is really incredible, so have you investigated why the old lady didn't reply?" Xu Tian asked.

"Of course, I had an in-depth investigation of this situation at that time, and I was also very concerned about my grandmother's behavior, because I found more than once that my grandmother's eyes were normal when she looked at others, and I found that my grandmother was pretending to be sick, in fact, she was very healthy, she did not have Alzheimer's disease, and she was not confused, but she had been pretending to be confused." Yu Yi said.

"I have goosebumps when you say it, the old man who is nearly seventy years old has been pretending to be confused, this really shouldn't be, there must be a deep reason behind this." Xu Tian said.

"It all came from the experience of the original grandmother when she was young, because since I landed on the island, there have been new people getting married in this village, and it is because of this that the grandmother has been playing dumb in front of the villagers." Yu Yi said.
