"Oh." Gongsun Jian nodded knowingly.

It should be that this Xiaoyu has been preparing for many days, and first used a poisonous teacup to let Miao Caiwei drink for a lot of time. Then, in the last few days, the set of poisonous teacups began to be taken out and everyone drank together.

In this way, there is no need to find any evidence at all.

Because the evidence has been erased a long time ago.

Even Gongsun Jian suspected that at this time, there could be no other evidence in the entire mansion except for this set of teacups.

Sure enough, when Zhang Mingyuan and Lin Zhutou came back panting with disappointment, Gongsun Jian understood that his guess should be correct.

"My lord, nothing poisonous was found." Because Lin Changqing and Zhang Mingyuan went early, they don't know what kind of poison it is.

"Did you find Tripterygium Vine?" Without waiting for Gongsun Jian to speak, Zhao Yang, who was on the side, asked curiously.

"Tripterygium wilfordii? Is that thing poisoning? Lin Changqing glanced at Zhao Yang in surprise.

After all, he had also heard of Tripterygium Ratterium, and even used it at home. But it would have to weigh several pounds to kill someone.

But it's just a cup of tea, how can it be this thing?

Just as Lin Changqing wanted to remove this idea, he saw Zhao Yang nodding at him, and asked again: "Then have you found it?" ”

"I didn't pay attention! Who knows it's that? I'll go look for it with Zhang Yuanwai? Although he was very surprised that it was this thing, Lin Changqing was still ready to pull Zhang Mingyuan over to check it again.

"Okay, let's go." Hearing Lin Changqing's words, Zhang Mingyuan couldn't care that his body was already sweating, so he hurriedly followed Lin Changqing to find it again.

After all, it was his beloved wife who was killed, and although he was tired, he thought of his wife's tragic death.

He is not reconciled if he does not find out the truth!

However, before the two of them could make a move, Gongsun Jian smiled and spoke.

"Lin Zhutou, Zhang Yuanwai, you don't have to go, the murderer has already acted a long time ago, and it should be impossible to find Lei Gongteng."

"But my lord, how can the murderer be caught?" Zhang Mingyuan asked a little anxiously.

"I've already asked someone to call Shopkeeper Yang, and when he comes, ask who bought a large number of Tripterygium Wisteria, and then you will understand." Gongsun Jian said with a smile.

"Yes, sir." Seeing him say this, although Zhang Mingyuan was still a little unwilling, he could only follow Lin Changqing to hold his fists and take his life.

In fact, the reason why Gongsun Jian didn't let the two of them look for it again was because he found that when Lin Zhutou said this proposal, Zhang Xiaoyu had no expression at all.

So Gongsun Jian guessed that he either hid the thunder vine very well, or he had already thrown it away.

Turning his head to Zhang Mingyuan again, Gongsun Jian opened his mouth and asked, "Zhang Yuanwai, have you ever used Lei Gongyuan in your family?" ”

If Zhang Yuanwai's family has never used it, then as long as Shopkeeper Yang says that Zhang Xiaoyu has bought it, Gongsun Jian can let people arrest Zhang Xiaoyu.

But on the contrary, if their family has not used it, then this case will have to be investigated.

Hearing Gongsun Jian's words, Zhang Mingyuan carefully recalled it in his mind, and then said with some embarrassment: "My lord, I have bought insect repellent." ”

Sighing, Gongsun Jian's heart was a little disappointed.

At the same time, I was shocked by Zhang Xiaoyu, how many years would it take to plan for this to cause all the evidence to have nothing to do with Zhang Xiaoyu.

Compared with Gongsun Da Lei some time ago, Gongsun Jian felt that this was the difference between humans and animals.

Zhang Xiaoyu is a human, and that Gongsun Dalei is an animal.

Of course, Gongsun Jian just thought about it casually in his mind.

After all, Gongsun Dalei was a manslaughter, while Zhang Xiaoyu was a planned homicide.

These two situations cannot be put together.

It's just that in this way, Gongsun Jian is very curious. What kind of hatred does this Xiaoyu and Miao Caiwei have, after all, all the information now shows that the relationship between the two is very good.

The case was in a predicament for a while, Gongsun Jian did not speak, and the entire hall fell into a deathly silence.

And the murderer Zhang Xiaoyu did not show any flaws, he was still the same as just now. From time to time, he was afraid of being mistaken for a murderer.

Of course, her expression is pretending in the eyes of Gongsun Jian, but in the eyes of others, it may be the expression she should have.

After all, only Gongsun Jian knew that Zhang Xiaoyu was the murderer through the system, while no one else knew who the murderer was.

Soon, Gu Qing hurried over with the shopkeeper Yang from the pharmacy.

Because of his age, even if Shopkeeper Yang walked slowly, he was sweating and panting.

First of all, he looked curiously at the surrounding officials and the people in the Zhang Mansion, and the shopkeeper Yang hurriedly came to Gongsun Jian, clasped his fists with both hands, and said respectfully: "My lord." ”

Smiling slightly, Gongsun Jian hurriedly spoke: "Shopkeeper Yang, I called you here today because I have something to ask, I hope you don't hide anything." ”

Hearing Gongsun Jian's words, the shopkeeper Yang on the opposite side immediately stood up straight and said with a reassuring face: "Don't worry, my lord, as long as you ask, the villain will definitely not hide it." ”

"In that case, then I'll ask." Smiling slightly, Gongsun Jian then said, "I don't know if there is a thunder vine in the shopkeeper Yang?" ”

"Tripterygium wilfordii?" Shopkeeper Yang glanced at Gongsun Jian in some surprise, after all, only he sold it in his pharmacy in the entire Tianyuan County, and he couldn't understand why Gongsun Jian asked knowingly.

However, Gongsun Jian was a county magistrate after all, and he couldn't ask anything, so he hurriedly said: "My lord, there is indeed Lei Gongteng in the villain's shop." And, if nothing else, only my pharmacy sells it in the entire Tianyuan County. ”

At the end, Shopkeeper Yang nodded very convincingly.

"Then I don't know if it's inconvenient for the shopkeeper Yang to tell me, has anyone in the Zhang Mansion bought Tripterygium Thunder in your pharmacy?" Gongsun Jian opened his mouth and asked the most crucial information.

"This, the villain is not very clear, after all, so many people in Tianyuan County have come to buy Thunder Kung Wilford, I can't remember them all, right?" Shopkeeper Yang said with some embarrassment.

However, just when Gongsun Jian was about to give up investigating the case and directly wanted to arrest Zhang Xiaoyu. Shopkeeper Yang said something that made him give up this decision.

"My lord, although I can't remember who bought it, I have an account book there, and there should be a record." Shopkeeper Yang said with a smile.

Hearing this, Gongsun Jian breathed a sigh of relief, but just as he was about to ask Gu Qing to get the account books.

Zhang Xiaoyu, who had not spoken just now, spoke.

"My lord, the little woman once bought Tripterygium Thunder in the shopkeeper Yang's shop." Zhang Xiaoyu made a nervous look on the surface and said timidly.

"Did you poison Madame?" Zhang Xiaobao on the side shouted in disbelief.

Since Miao Caiwei was poisoned by Tripterygium Thunder, the biggest suspect is the person who bought Tripterygium Vine.

Hearing Zhang Xiaobao's questioning, before Zhang Xiaoyu could defend himself, Zhang Chenglin on the side hurriedly said: "Xiaobao, don't talk nonsense, Xiaoyu has such a good relationship with her aunt, how could she poison her aunt?" ”

Seeing Zhang Chenglin defending himself, Zhang Xiaoyu over there hurriedly thanked him.

"Thank you, young master, thank you, young master, it is absolutely impossible for me to kill Madame."

Seeing this, Zhang Chenglin on the side hurriedly smiled and said, "You don't have to thank me, after all, your relationship with your aunt is so good, you must be the least suspicious." ”

Hearing Zhang Chenglin's words, Zhang Xiaoyu over there was even happier.

Zhang Xiaobao, who was on the side, was muttering in a low voice: "Maybe it's her!" Who knows if her heart is red or black? ”

Although his voice was very small, basically everyone present heard it, so Zhang Chenglin was naturally no exception.

"Xiaobao, don't talk." Zhang Chenglin frowned and interrupted Zhang Xiaobao's words.

Seeing that he was angry, Zhang Xiaobao on the side quickly closed his mouth.

However, unlike Zhang Chenglin, Gongsun Jian, who was sitting above, was a little curious about Zhang Xiaobao's words.

After all, he knew very well that Zhang Xiaoyu was the murderer.

It stands to reason that they are both from Zhang's house, no matter how bad the relationship between Zhang Xiaobao and Zhang Xiaoyu is, at least now they have to be a little sad, right?

But Zhang Xiaobao was not like this, and he even suspected that Zhang Xiaoyu was the murderer.

Could it be that this Xiaobao knows something?

For a while, Gongsun Jian fell into deep thought.

However, at the same time, Gongsun Jian did not forget one thing.

"Lin Zhutou, please send someone to the shopkeeper Yang and bring the account book." Gongsun Jian glanced at Lin Changqing and said.

Actually, originally he wanted Gu Qing to get it, but then he thought about it again and again, he had to give him a little sweetness, right?

So he left Gu Qing to handle the case with him.

"Yes, sir." Lin Changqing, who was over there, heard Gongsun Jian's order, hurriedly clenched his fists and took the order, and then sent someone to walk out with Shopkeeper Yang leisurely.

There's no way, Shopkeeper Yang is old after all, and he has walked a lot just now, so how can he have any strength at this time!

On the other side, many people present were puzzled by Gongsun Jian's sudden order.

After all, Zhang Xiaoyu admitted just now that he had gone to the pharmacy to buy Tripterygium wilfordii.

But now why does Gongsun Jian want to take the account books back again?

Seeing that everyone was puzzled, Gongsun Jian didn't have the heart to explain anything.

After all, sometimes it's still necessary to maintain a sense of mystery for a reason.

Although they can't figure it out now, when the case is over, when they think about it, most of them will suddenly realize.

will even have a hint of admiration for Gongsun Jian, making it easier for him to gain popularity points.

In fact, there are two reasons why Gongsun Jian wants people to go to the store with Shopkeeper Yang to bring the account books.

One is that the other clues have been broken, and he can only look for evidence in the account books.

The second is that generally speaking, the most worrying place for prisoners is the place where they show the most flaws.

Just now, Zhang Xiaoyu said that she had bought Lei Gongteng, although in the eyes of many people, she was open-minded.

But in the eyes of Gongsun Jian, who has long understood that she is a murderer, this is to cover up his flaws.

Especially when he asked people to follow Shopkeeper Yang to get the account book, Zhang Xiaoyu's eyelids that kept beating made Gongsun Jian understand that there was definitely an article in this account book.

When Shopkeeper Yang left, Gongsun Jian was not idle, first leaving Zhang Mingyuan behind, and then letting Lin Changqing leave the hall with the other three.

Although a few people left, the hall that was full of people just now instantly became empty.

At this time, Zhang Mingyuan didn't know what he was thinking, and when he saw that Gongsun Jian left him alone, he didn't have any superfluous expression.

Gongsun Jian stepped down from his seat and stood in front of Zhang Mingyuan.

"Zhang Yuanwai, who do you think poisoned your wife?" Gongsun Jian suddenly asked.

These words made Zhang Mingyuan on the other side finally lift a little spirit.

didn't surprise Gongsun Jian, Zhang Mingyuan on the other side insisted and said: "My lord, it was the villain who killed him." ”

It's just that Gongsun Jian is not satisfied with his answer at all.

Shaking his head, Gongsun Jian continued to ask, "Aside from you and Zhang Chenglin, who do you think is the most likely?" ”
