"Okay, you didn't see me, you're all targeting me, aren't you?" Chen Po said angrily.

"I didn't say that the murderer must be you, now I'm just asking what everyone was doing at the time, so the next is Jiaojiao, have you been sitting in the front hall?" Xu Tian asked.

"Almost! I have been sitting at the door of the front hall, because it was a little cold, I also went into the front hall to warm up, but the door has been open, if I go out, Teacher Jin and Chen Fan should see me, if Chen Po has been on the road, she should also be able to see me. Jiaojiao said.

"Okay, Dongzi, you were cleaning the road leading from the front yard to the guest room, right?" Xu Tian asked.

"Yes, because there was already snow on the road at that time, and the road was slippery, so that's my daily job." Dongzi said.

"Teacher Jin, you should be staring at the study at the same time as Chen Fan, right?" Xu Tian asked.

"To be precise, I've been staring at Chen Fan, he hasn't left, I can prove it." Teacher Jin said.

"But you've been out of my sight, I've been staring at the back of the study, you're at the front of the study, and I haven't noticed you, though I know you seem to be looking at me all the time." Chen Fan said.

"Okay!" Teacher Jin lit a cigarette and said. "To be honest, in fact, I didn't keep an eye on you, I was worried about Mr. Fang's safety, but I didn't see anyone at the gate of the courtyard but it's true."

"Then the last one is Siyan, did you come back from outside today?" Xu Tian asked.

"Yes, as soon as I entered the door, I saw Dan Xin nailed to a dead tree, and after a few seconds, you appeared one after another, fortunately there was already snow on the ground at that time, otherwise I really wouldn't be able to tell." Siyan said.

"May I ask you what you're doing today?" Xu Tian asked.

"I went to look for you, I followed your footsteps when you and Teacher Jin left Chen's house this morning, but then I lost it, and I didn't return to Chen's house after that, I thought about walking around the village, that's all." Siyan said.

"Why did Siyan lose us? It's a bit unscientific. Xu Tian said.

"Because I just walked out of Chen's house not long ago, I was stopped by Danxin, I said a few words to Danxin, and you were gone, and then I didn't come back with Danxin, so I went to the strange slope." Siyan said.

"What did Dan Xin tell you?" Xu Tian asked.

"It's nothing important, just tell me to pay attention to safety when I get to Fang's house, and don't wander outside for too long." Siyan said.

"It's reasonable, but Siyan should still be grateful for this blizzard, otherwise Siyan will be directly accused of being the murderer." Xu Tian said.

"It doesn't matter about this matter, now that Danxin has been killed, who killed Danxin is the most important thing." Siyan said.

"That's right, you should find the murderer of Dan Xin first." Mr. Fang said.

"Then let's take a look at Chen Fan's lawyer's certificate!" Xu Tian said.

Chen Fan opened the suitcase in public, and there was indeed a lawyer's certificate inside, and both Mr. Jin and Siyan could prove that the lawyer's certificate was real, and they also checked Chen Fan's ID card, and Chen Fan's identity information was also true.

"The last one is Li Nana, I remember that after hearing Siyan's shouting, Li Nana was the last to run to the front yard." Xu Tian said.

"Because I've been in the kitchen, I didn't hear anything, I just ran over to find Mr. Fang, but who knew that I saw this kind of thing in the front yard." Li Nana said.

"You didn't hear anything?" Xu Tian asked.

"Yes! I didn't really hear anything, I was in the kitchen all the time. Li Nana said.

"She's right." Chen Po said. "The kitchen is far from the front yard, and the pot in the kitchen must be either boiling water or stir-frying, and it is normal not to hear the sound of the front yard."

"This is everyone's respective alibi, and for the time being, Mr. Fang, Mr. Jin and Chen Fan can be excluded, this is my temporary conclusion." Xu Tian said.

"That's right, Chen Fan really didn't have a chance to slip out from under my nose, and it was even more impossible for Mr. Fang to leave the study that was stared at by me and Chen Fan, and Jiaojiao was still in the front hall behind the study at the time, so it can be said that Mr. Fang was in an absolutely closed space." Teacher Jin said.

"I'm so popular, so many eyes are on me." Mr. Fang teased.

"There are also Chen Po, Jiaojiao and Dongzi, the alibi of the three of you is relatively vague, but from the geographical location, the probability that the three of you can go to the gate of the courtyard and kill Danxin is very small, especially Chen Po and Jiaojiao, an old man, a thin girl, you two should not have the strength to insert the steel bar into Danxin's chest, and those two steel bars also pierced the dead tree, this is not something the two of you can do." Xu Tian said.

"Then it's probably me!" Siyan said.

"But Siyan's footprints didn't stay around Danxin's body, and with that, Siyan could be excluded." Xu Tian said.

At this time, everyone's eyes were on Li Nana, and Li Nana, who knew that she was being suspected, panicked, and couldn't even speak.

"No...... No...... Not me! Li Nana said.

"Why didn't there leave footprints around Danxin's corpse for the time being, I can only be suspicious of you after unlocking it, don't be afraid, you are currently the same as Siyan, the question of not leaving footprints around Danxin's corpse has not been answered, and neither you nor Siyan will be listed as suspects." Xu Tian said.

"It seems that I haven't completely ruled it out." Siyan said.

"I can prove to Nana that she didn't go to the front yard." Mr. Fang said.

"You prove?" Xu Tian said suspiciously.

"Yes, I can prove that the murderer is not Nana." Mr. Fang said.

"Do you see who the murderer is?" Xu Tian asked.

"I didn't see it, but it's certainly not Nana." Mr. Fang said.

"Why are you so sure?" Xu Tian asked.

"Because...... Nana didn't come to the Chen family this time to kill Danxin, but I asked her to help get rid of everyone in the Chen family except Danxin. Mr. Fang said.

"Poisoning food?" Xu Tian said with a sinking face.

"That's right, I originally planned to let Danxin come to the study to accompany me for lunch, if I call you and this Teacher Jin, you will definitely come too, Nana was brought by me, and it is not too much for me to ask Nana to accompany me." Mr. Fang said.

"Then the rest of the Fang family will eat other dishes, you let Li Nana poison other people's food, is that what it looks like?" Xu Tian said.
