In Zhang's office, Xia Xi saw Zhao Shuo's purple qi again, as well as a small cloud of black mist wrapped in purple qi, which he extracted from the second kitchen knife and carefully wrapped it in purple qi to prevent it from being swallowed by purple qi.

"It's the one who committed the crime!" Zhao Shuo pointed to the black mist in the purple qi.

"A cloud of fog, how can it commit crimes?" Zhang Ju's brain was a little out of turn.

"Zhao Shuo, did the black fog control the murderer's brain and let him commit the murder? But this doesn't make scientific sense, it doesn't make sense! Xia Xi realized it later, but his mind was still full of questions.

"So, do you think that Principal Situ Lanxue can be explained by being controlled by the black fog? Principal Situ is a scientific researcher, and his willpower is definitely much stronger than that of the murderer, but in the face of the black fog, he has no power to fight back, and he is controlled in an instant and loses himself, isn't this the same as the murderer's performance? Zhao Shuo asked rhetorically.

"Xiao Xia, what's the matter with Principal Situ?" Zhang Ju asked suspiciously.

This matter is like this...... Xia Xi told Zhang Ju what he knew. Zhang Ju fell into deep thought.

The evidence that can be found now is the kitchen knife, but the kitchen knife is the murderer, which is unjustifiable! Zhang Ju questioned.

"No, it's not a kitchen knife. There is a problem with the kitchen knife, and the crime is committed by the black fog and the existence behind the black fog! Zhao Shuo said with certainty.

"I don't know if it's a person or a monster behind the black fog, but there's definitely an invisible hand controlling the black mist. The black fog resides in a kitchen knife, and the murderer uses a kitchen knife to control the crime. Therefore, kitchen knives are just a medium. Zhao Shuo analyzed.

"Why do the people behind that control kitchen knives to kill people? What is the purpose? Xia Xi asked. Although what Zhao Shuo said has some truth, this is the only inference that can explain the serial case at present. But all murders will have a reason, and what is the reason for these serial cases?

"Actually, I don't know the reason, I only came into contact with this black fog yesterday, and I have a lot of questions about the black fog in my heart, and we need to continue to investigate." Zhao Shuo said with a wry smile.

He doesn't know anything about the weird black fog, and the only hole card is that his skills can detect the black fog and restrain him, so he can investigate boldly and without worrying about life.

"It's so shocking that I can't make up my mind, let alone explain it to you. That's it, Xiao Zhao, I believe in you, let Xia Xi cooperate with you to solve the case. Imperial guards are needed, Xia Xi can be deployed at any time, but this matter must be kept secret, and the fewer people who know, the better! Zhang Ju replied cautiously.

Whether it is the reason Zhao Shuo said or not, this matter is not trivial, if he is not careful, it will cause social instability, and he needs to make careful decisions. At the moment, this is the best solution he can provide.

"Well, Uncle Zhang, I know your difficulties. Rest assured, we will be able to solve this case and prevent more innocent people from dying! Zhao Shuo said heavily.

"Hehe, I'm old, I'm useless, and I'm really powerless to deal with these things." Zhang Ju sighed and continued: "Xiao Xia, on behalf of the Security Bureau, you will fully cooperate with Zhao Shuo and solve the case as soon as possible!" ”

"Imperial guard Xia Xi, police number: JXXXXXXXXX, resolutely complete the task!" Xia Xi stood up and accepted the order.

Kitchen knife! Kitchen knife! Everything is a kitchen knife! If you want to solve the case, you need to find the same kitchen knife again and find out the source of the kitchen knife.

All afternoon, the two of them wandered around different civilian markets and supermarkets, looking for kitchen knives.

Until the afternoon, the same kitchen knife was not found.

At this time, Lan Duoer called and asked for his opinion, saying that Yang Yutong asked her to move in and live together. A girl who lives in a chaotic shantytown and has just been killed today is very inappropriate.

Of course Zhao Shuo agreed, this little girl, with herself, has not taken care of others, and having Yang Yutong to take care of him can make him more at ease.

He thought that it was inconvenient for Lan Duoer to be alone, so he told Xia Xi that he would also go over to help.

Xia Xi found nothing for a kitchen knife, and he was tired of looking for it, so he asked to go over to help, and Zhao Shuo agreed. Xia Xi drove the locomotive and followed Zhao Shuo to the shantytown.

"Zhao Shuo, I heard you mention that Uncle Zhao also lives in this building?" When Zhao Shuo was chatting with a few girls, he once mentioned it.

"Eun, yes, he lives on the first floor, very close to the one where the accident happened." Zhao Shuo replied.

"That's just right, let's go and see if Uncle Zhao can provide me with valuable clues! It won't take long anyway. Xia Xi said with sudden interest.

This police flower, as soon as she encounters a case, becomes a workaholic, eats, sleeps and does things, her mind is full of cases, and she does not miss the slightest opportunity.

"Eun, let's see what we can find." After speaking, Zhao Shuo took Xia Xi to Uncle Zhao's corridor.

"Wow, this can live too!" Xia Xi was so surprised that she couldn't close her mouth. This wealthy lady has been clothed and fed since she was a child, and she never imagined that there would be people living in such a cramped, shabby, and messy place.

"Hehe, life is not easy, not everyone is born with everything. In society, elites and successful people account for only a small part, and most of them are these ordinary people who get up early and are greedy for darkness, and have a lot of food and food. In the future, you will enforce the law, and don't make it too difficult for them. Zhao Shuo said lightly.

"Hmm!" Xia Xiqiao blushed and responded softly. This self-righteous policewoman, who mostly ignores the advice of others, is rare to be able to follow Zhao Shuo's advice today.

"Uncle Zhao, I'm Xiao Shuo, are you at home?" Zhao Shuo stood outside and shouted.

Yesterday, there was such a big thing in the community, it is estimated that Uncle Zhao will take leave to stay at home, because he still has a student who needs to be comforted and stable, otherwise he will be panicked and will affect his studies.

"Oh, Xiao Shuo is here." Sure enough, the wooden door creaked, Uncle Zhao poked his head out, saw Xia Xi and Zhao Shuo, and immediately understood what it meant, and said apologetically: "The room is narrow, please come in"

Xia Xi leaned sideways, bent over, and followed Zhao Shuo tightly to the corridor.

"Huh! How is this kitchen knife exactly the same as a crime tool? "When Xia Xi passed by the simple kitchen in the corridor, he found a kitchen knife hanging on the wall.

"Well, I see!" Zhao Shuo suddenly realized, no wonder when he checked the scene, he always found that he had seen the same kitchen knife somewhere, but he never thought that it was at Uncle Zhao's house.

I searched for a day at noon and didn't find any clues, but I didn't expect to find them in this inconspicuous place.

It's really a village with no way out, and the willows and flowers are bright and another village!

He glanced at Xia Xi gratefully and gave her an appreciative look.

"Humph!" Xia Xi raised his head proudly, straightened his chest, and then blinked his eyes mischievously, quite a feeling of raising his eyebrows.

All along, it was Zhao Shuo who took her away, and finally showed her strength! Actually, in some ways, women are more delicate than men.

"Poof!" Zhao Shuo's blood surged for a while, and he almost spurted out a nosebleed.

This little girl, don't you know that your chest will break the buttons!
