"Wu Shilang, I'm back."

Li Zhen's loud voice broke the silence of the Yayuan Residence.

"How? Is this food poisonous? Wu Tianyi was also very curious and asked anxiously.

"I took it to the doctors of all sizes in this secluded capital city, and they all said that this wine and food are not poisonous."

Li Zhen gasped heavily, but the words he said were still clear.

"Not poisonous?"

Wu Tian was taken aback, and then seemed to think of something again, and continued:

"It's right if it's not poisonous, it means that the murderer is this Wang Hongsheng. He had been with the deceased from last night until this morning, and the door was so locked that no one could open it. And now that Zhou Dao is dead, and Wang Hong is still alive and well, isn't this full of suspicions? ”

"I'm suspicious of what you're saying."

Yan Nuo glanced at Wu Tianyi and said lightly, "It is precisely because there is no poison in this wine and food, so the murderer is not Wang Hongsheng." ”

"What kind of logic are you? Then do you know what kind of poison died in this Zhou Dao Institute? ”

Wu Tianyi was a little unconvinced, he was also a martial servant of the Criminal Department, and when he was replied by this little girl, he couldn't hold back a little on his face, so he directly asked about the doubts in his heart.

"As I said earlier, the poisonous weeds in him are very common, and I guess they are found in the surrounding mountains. This poisonous herb is called Yuyigan, which can be used as a traditional Chinese medicine when dried, but it is highly toxic in the fresh juice. ”

Yan Nuo pondered deeply, if it weren't for the fact that this kind of poisonous weed was too common, she probably wouldn't know so many details.

The reason why the murderer didn't take the trouble to pick this poisonous weed was that he didn't want to make people suspicious, it seems that the murderer was an extremely delicate person.

"Hehe, according to what you say, I still suspect that this Wang Hongsheng deliberately used this poisonous weed to poison Zhou Dao and deliberately did not leave, because the most dangerous place is the safest place."

Wu Tianyi sneered at the corner of his mouth, the limelight was repeatedly covered, the jealousy in his heart was really unbearable, and he retorted contemptuously.

"Well, what Wu Shilang said makes sense."

Yan Nuo nodded, glanced at Wu Tianyi, who had a smug expression on his face, hooked the corners of his mouth, and continued: "Then I have a few questions, I want to ask you." ”

"Ask, what's the problem?" Wu Tianyi waved his hand heartily, and his heart was also filled with a bit of vanity.

"Then why did the key to Zhoudao's room appear under this table? There is only one key to this one, there is no backup, and it should be kept safely. ”

Yan Nuo said, pointing to the original table foot, then took out the key in his hand and shook it in front of Wu Tianyi's eyes.

"It's not difficult to explain this, the horse has a hoof, the person is frustrated, and he accidentally dropped."

Wu Tianyi smiled easily and blurted out.

"Okay, what about this book? Hua Shang just said that this week has always had a habit of cleanliness, and everything that has been used will be placed in its place, so why is this book placed on the edge of the table? And it was going to fall to the ground and didn't care? ”

"I all know that he was drinking with Wang Hongsheng last night, who knows if he was drunk? Confused. ”

Wu Tianyi disagreed, shook his head, and thought how powerful this little girl was, but it turned out to be just a fox and a fake tiger, so he asked some if there was any.

"The most important point, since Wang Hongsheng is the murderer, why didn't he kill Zhou Dao directly with a knife, but went up the mountain to pick poisonous weeds tirelessly?"

"Heh, of course he is afraid that blood will be splashed everywhere, or he is afraid that the cries of this Zhou Dao will attract students and catch this Wang Hongsheng on the spot."

"Hehe, it seems to be contradictory again! Wu Shilang, you first said that the most dangerous place is the safest place, since he is about to kill someone, why do you care about killing Zhou Dao by what method? Also, he didn't run away when he killed someone anyway, so why was he afraid of attracting students to catch him red-handed? ”

Yan Nuo asked with a smile, directly leaving Wu Tianyi speechless and embarrassed in place.

"Peiyun, wait, you made my head dizzy, you said that the murderer is not Wang Hongsheng, who is the murderer?"

Qu Yiyu looked at Yan Nuo and asked anxiously.

Yan Nuo shook her head, indeed, she didn't know who the murderer was now.

One thing is for sure, this person is the person in this Siyuan study.

First of all, when the deceased Zhou Dao died of ugliness, at that time everyone had already rested, and only those who were familiar with the study would smoothly enter the study and then commit murder...... Into the study? Anti-lock in the study? Key...... That's right!

Yan Nuo slapped his head, "Why am I so stupid." He muttered to himself and walked to the door of the study and looked closely.

"Peiyun, what are you looking for?"

Qu Yiyu was curious, followed behind Yan Nuo, and asked in surprise. But what answered Qu Yiyu was a silence.

Yan Nuo looked at it for a long time, and went directly to the study opposite this Yayuan Residence, Shang Wenju.

"Sure enough, the murderer really used this method to kill people......"

Yan Nuo muttered to himself and returned to Yayuanju.
