"I told you a long time ago that I don't need your protection." Xiao Ai opened the curtain and said.

"I'm sorry, I found the clue too late this time, otherwise I might have prevented Li Nana from being killed." Xu Tian said guiltily.

"Do you think this is your dereliction of duty as a detective, or are you being played by the murderer? At that time, when Li Nana was killed, you were always with Dongzi. Xiao Ai said.

"You're right, but Dongzi and I didn't stay together after leaving the boiler room, I walked out of the boiler room first, and when I suddenly thought about why Siyan in the kitchen next door didn't look for me, I walked directly to the kitchen, and I also glanced at the boiler room at that time, and I saw Dongzi follow me out of the boiler room, and Dongzi didn't lock the door of the boiler room, but hung the lock on the door." Xu Tian said.

"You found out too late, and you did something very fatally wrong at the time." Xiao Ai said.

"That's right, this matter is indeed what I did wrong, I underestimated the murderer's ability to act, in fact, I should have thought that the murderer was Dongzi, a person who could wait for us for a day in the cold wind, and his endurance was absolutely extraordinary." Xu Tian said.

"The most important thing is that Dongzi doesn't have a mobile phone on him, or he waits for us for a day on the edge of the barren grassland, so that there is no entertainment life and boring life waiting for us all day, which is definitely not something ordinary people can do." Teacher Jin said.

"This point is a bit ridiculous, Mr. Jin complained too seriously." Xu Tian said.

"Then I have roughly speculated about the process of Li Nana's murder, Xu Tian, do you know where your own shortcomings are now?" Teacher Jin lit a cigarette and said.

"It's okay for me to exercise now, but it's still a bit difficult for me to be a strong person, if I had been trained since I was a child......"

Xu Tian was suddenly stunned, and at this time, pictures from his childhood appeared in Xu Tian's mind.

It was also a snowstorm night, Xu Tian stayed in a small dark room with a girl a few years older than him, who was that girl? The last time Xu Tian dreamed of this dream, the picture ended when the girl showed a terrifying smile after burning the house.

"Why are you stunned?" Teacher Jin said to Xu Tian.

"I ...... It's okay, let's talk about the case! It was indeed because of me that Li Nana was killed at that time, and if I had been a little more athletic, maybe I could have saved Li Nana. Xu Tian said.

"Don't blame yourself, it's not your fault, the murderer was prepared in advance, but you are not merciful to everything, in that case, you can't expect the murderer to want to kill Li Nana, even if you have a strong skill, you may not be able to prevent the tragedy of Li Nana's murder." Teacher Jin said.

"If you say that, I can feel a little better, Dongzi used me to make an alibi for him, this is indeed Dongzi's smartest move, but I don't understand, why did you make that row of big footprints outside?" Xu Tian asked Dongzi.

"I haven't understood what you're talking about." Dongzi said with a gloomy face and a smile.

"Then I'll let you understand that the way you killed Li Nana was to hang the lock on the door of the boiler room after we left the boiler room and then went to the front yard. But the snowstorm was so hard that I could barely see you when you walked five meters away, and instead of going to the front yard, you went around to the back of the kitchen, or to the side of the boiler room, as long as you could get to the roof. After that, you tried to manipulate the pre-designed mechanism to kill Li Nana, and the blood stains on the ground were the result of your manipulation of the mechanism, am I right? Xu Tian said.

"What about the evidence?" Dongzi said.

"Don't worry, I'll convince you. Let's talk about the mechanism you used first, if my reasoning is correct, you should use Xiao Ai's computer to buy some remote control equipment online, if we go to search the kitchen again now, we will definitely find traces of the equipment. Xu Tian said.

"If you had that kind of instrument, wouldn't you be able to see it? You are slandering me by saying this. Dongzi said.

"Then do you dare me to search your body?" Xu Tian said.

"Whatever you want, anyway, what you said doesn't correspond at all, if I had that kind of killing device, I would have killed you all one by one." Dongzi said.

"You don't have the guts." Teacher Jin said to Dongzi in a mocking tone.

"What do you say? Are you underestimating me? So do you want to try it? Dongzi looked at Teacher Jin viciously and said.

"Your biggest failure is to put Li Nana's body in the boiler, as well as the inexplicable human head, and the evidence of the murder you are accused of is on that human head." Xu Tian said.

……

While the snowstorm was still blowing outside, two strangers came to the temple of the dog god, and one of the young men sprinkled a few handfuls of cat food on the ground, and poured some mineral water into the bowl to feed the hungry and thirsty cats.

"They're almost done, right?" Said the man with a stubble on his face.

"It's hard to say, it depends on whether the kid you choose will succeed." The young man said.

"If he doesn't succeed this time, our plan will be postponed again." Said the man with a stubble on his face.

"Why don't you just kill that detective and detective? You also had so many opportunities before, but you didn't do it every time, this time the two of them are two lambs to be slaughtered in this deserted village, as long as you give an order, you don't need the greedy ghost in the Chen family's ancient mansion to make a move, I can help you get rid of them. The young man said.

"I want to see what smart people who are cornered will do, and the desperate eyes they have, and it will be a very exciting time." Said the man with a stubble on his face.

"But don't forget, there is still that person by their side, and if that person does something that disappoints you again at a critical moment, I'm afraid we'll be playing in vain this time." The young man said.

"No, she doesn't have much time left, all she can do now is to obey our orders, if she dares to disobey the order again, she will not have a chance to continue her life for the next four years." Said the man with a stubble on his face.

"If she dies, I'm afraid it will also be a fatal shock to that big man, aren't you afraid of being blamed?" The young man said.

"God doesn't know it, I won't be that stupid." Said the man with a stubble on his face.
