Suddenly, Gongsun Jian opened his mouth and asked Zhao Yang.

"Zhao Yanzuo, what kind of poison caused Miao Caiwei's death?"

"My lord, it will take about half a day to find out." Receiving the call of Gongsun Jian, Zhao Yang, who was standing in the yamen, hurriedly walked out.

Nodding, Gongsun Jian said to him: "Hurry up and check, this official is waiting for you here." ”

"It's my lord, my subordinates will go and check." Respectfully clenching his fists at Gongsun Jian, Zhao Yang hurriedly ran to the room where Miao Caiwei died, took out the poisoned teacup, and then ran out of Zhang's mansion with a smoke.

After all, there is no test equipment in the yamen in Zhang's mansion.

To be honest, when I used to watch TV series, Gongsun Jian thought that these pretenses were investigating the cause of death or something based on experience.

But after really going to Zhao Yanzuo's room to take a look, Gongsun Jian couldn't help but sigh that the wisdom of the ancient working people was also infinite.

People also have test equipment, after all, thousands of years of work as a profession, if there is no test equipment, how can novices find out the cause of death!

Veterans have a lot of practical experience, but novices don't have that much practical experience.

Although these test equipment are relatively rudimentary, some causes of death that are not truly unsolvable can still be identified.

After Zhao Yang left, Gongsun Jian was not idle, he looked at Zhang Mingyuan and asked, "Zhang Yuanwai, is it okay to have someone search your room?" ”

"Yes, sir."

There was no hesitation, it seemed that Zhang Mingyuan also wanted to find the murderer of his wife, so he agreed directly.

Nodding, Gongsun Jian said to Lin Changqing: "Lin Zhutou, you follow Zhang Yuanwai to search all the rooms in the mansion." ”

"Yes, sir." Lin Changqing clenched his fists and took the order, and then walked out of the hall with Zhang Mingyuan.

In Da Zhou, if you want to search the room, you must be in front of the owner, and there can't be too many people.

After all, there are so many people that it wouldn't be good if something was lost in the room.

When the time comes, not to mention the loss of face of the Great Zhou court, even the people of the Great Zhou will not be happy.

It's just that Gongsun Jian was a little surprised that Lin Zhutou hadn't searched a few rooms yet, so he ran over under the pretense of Zhao Yang.

With a happy face, he said to him, "My lord, the poison has been identified. ”

"What kind of poison?" Gongsun Jian hurriedly asked.

"Thunder Vine!" Without hesitation, Zhao Yang hurriedly answered Gongsun Jian's words.

Listening to Zhao Yang's answer, Gongsun Jian glanced at Zhang Xiaoyu, who suddenly shook his body over there.

The heart is really this thing.

Although he didn't know what it was, looking at Zhang Xiaoyu's reaction could show that this was the kind of poison she had given.

Moreover, there is a high chance that it can be bought in Tianyuan County.

So Gongsun Jian asked Zhao Yang directly: "Zhao Yanzuo, where can I buy Lei Gongteng?" ”

"My lord, this kind of thing can be bought in ordinary pharmacies, because many people mainly use it as a deworming medicine. Although it is said that boiling a small amount of soup can also cure some physical pain, if you cook too much, it will not be long before you die of poison. ”

"Boil? Does it taste the same as tea? Gongsun Jian suddenly asked a question.

"Yes, my lord, this thunder wilfordii tastes very bitter after cooking, and it does taste the same as some inferior tea." Zhao Yang replied honestly.

Hearing Zhao Yang's answer, Gongsun Jian's eyes lit up, and he looked at Zhang Xiaoyu, who was already trembling slightly, and Gongsun Jian thought of something in his heart.

It should be this Zhang Xiaoyu who put Lei Gongtian into the kettle when he boiled the water, so Zhang Xiaobao didn't notice it at all.

Thinking of this, Gongsun Jian turned his head to look at Gu Qing, "Gu Qing, you go to the kitchen and bring all the kettles." ”

"Yes, sir." Gu Qing didn't talk nonsense, and directly hugged his fists to lead his life.

After he left, Gongsun Jian looked at Zhang Xiaoyu.

"Zhang Xiaoyu, you said that you boiled the water last night, so did you put the thunder vine?"

"My lord, I didn't put it." Zhang Xiaoyu shook her desperately, looking at her like that, it seemed that she was really worried that Gongsun Jian would treat her as a murderer.

Seeing this, Gongsun Jian was curious.

Because, according to Zhang Xiaoyu's careful plan, she would not have left this clue, let alone show such an easily exposed expression.

Could it be that there is fraud in this?

After a while, Gu Qing ran over with several kettles.

Without waiting for Gongsun Jian to speak, Zhao Yang himself took the initiative to run over to check the kettles.

After carefully checking it several times, Zhao Yang shook his head at Gongsun Jian.

"My lord, all the kettles here don't smell of Tripterygium Ivy."

Now Gongsun Jian began to have a little brainstorm, if it weren't for these kettles, it wouldn't have been thrown away, right?

Therefore, Gongsun Jian opened his mouth and asked Zhang Xiaobao: "Zhang Xiaobao, go and take a look, is there a lack of kettle?" ”

Hearing Gongsun Jian's order, Zhang Xiaobao didn't dare to hesitate, and hurriedly ran over, and after checking it several times, he said with certainty: "My lord, we only have these kettles in our house, and there are many of them." ”

Sure enough, Zhang Xiaoyu will definitely not leave any loopholes.

Gongsun Jian even suspected that her nervousness just now was all performing.

Because he knows that Zhang Xiaoyu is the murderer, but others don't know!

Therefore, Zhang Xiaoyu was nervous just now, although in Gongsun Jian's opinion, it was revealed because he was afraid of being arrested.

But in the eyes of others, it may be only because of the fear of being mistaken for the murderer, so they are nervously afraid.

Seeing the suspicion in the eyes of everyone around her disappear, Gongsun Jian had to admire her clever methods.

It's a pity that Gongsun Jian knew that Zhang Xiaoyu was the murderer from the beginning, so he would not give up at all to continue to investigate Zhang Xiaoyu, who was no longer suspected.

Suddenly, Gongsun Jian thought of a question, since there is no smell of thunder vine on the kettle, is there one on the teacup?

Of course, there is a suspicion that the entire teacup has been steamed by Tripterygium Teng, and the poison may have penetrated into the teacup.

Gongsun Jian first asked Zhang Xiaobao, "Zhang Xiaobao, who gave you that teacup you served last night?" ”

"My lord, I got it straight from the kitchen." Zhang Xiaobao was a little surprised, he couldn't understand why Gongsun Jian asked this.

"When you took it, how many teacups were there in the whole set?" Gongsun Jian asked the most crucial question.

If there is only one, then it means that the teacup is most likely infiltrated by poison.

It's just that Zhang Xiaobao's answer made Gongsun Jian a little disappointed.

I saw that he thought for a moment and then said, "My lord, there are four teacups in the whole set." ”

Gongsun Jian turned his head to look at Zhang Chenglin, "How many teacups did you have when you poured tea?" ”

When Zhang Chenglin was hesitant, Gongsun Jian found that his chin had been touched by Gu Qing just now, and it had not recovered yet.

Helpless, Gongsun Jian could only look at Gu Qing.

Gu Qing over there saw Gongsun Jian looking at him, and hurriedly ran over, and closed Zhang Chenglin's mouth with two clicks.

"My lord, when the villain pours tea for my aunt, there are also four teacups." Although Zhang Chenglin was a little unclear because he had been for a long time, Gongsun Jian still heard it.

Nodding pretendedly, Gongsun Jian's heart began to worry a little.

At this time, all the evidence has nothing to do with Zhang Xiaoyu.

It's just that Gongsun Jian didn't want to die, so he looked at Zhao Yang.

"Zhao Yanzuo, take all the teacups to check to see if they have been infiltrated by poison."

Hearing Gongsun Jian's words, Zhao Yang's eyes lit up over there, and he hurriedly hugged his fists to receive his life, regardless of fatigue, and ran back to the yamen with the teacup for Miao Caiwei to test.

Looking at the back of him leaving, Gongsun Jian was not idle, and turned his head to look at Gu Qing.

"Brother Gu, go and invite Shopkeeper Yang from the pharmacy."

There is only one pharmacy in the entire Tianyuan County, if Zhang Xiaoyu really bought it from the county, then there is only Shopkeeper Yang's shop.

As Gu Qing hugged his fists to receive the order, Gongsun Jian noticed that Zhang Xiaoyu's expression suddenly panicked, although she quickly regained her composure, Gongsun Jian still saw it.

It seems that it was really bought in Yang's shopkeeper Tripterygium Iysteril!

Gongsun Jian thought affirmatively in his heart.

Otherwise, Zhang Xiaoyu wouldn't have the expression she had just now, if it was just deliberate, she wouldn't have to take back that expression at all.

The happy events continued one after another, and soon Zhao Yang returned, and he said to Gongsun Jian with an excited expression: "My lord, it has been ascertained that these four teacups have all been soaked in poisonous water. ”

Gongsun Jian nodded, and then looked at Zhang Xiaoyu, whose expression was no longer calm, although he did not speak, but it still made Zhang Xiaoyu feel a lot of pressure.

The twitching legs from time to time at that time exposed her inner thoughts.

On the other side, hearing that the four teacups had been soaked in poisonous water, several people in the Zhang Mansion were a little shocked.

"Who is so ruthless that he wants to poison us all?" Gasping for air, Zhang Xiaobao shouted in shock.

After all, these four teacups were soaked in poisonous water, so wouldn't the tea they usually drink be poisonous?

It's just that as soon as he finished speaking, Zhang Chenglin, who was already able to speak normally, raised his own questions.

"And if all four teacups are poisonous? So why haven't we been poisoned? ”

"Someone." Hearing his question, Gongsun Jian shouted at the servant.

Immediately, a servant stood up respectfully.

"Your Excellency, please command!"

"Go to the kitchen and see if there's another tea set?" Gongsun Jian instructed him.

"Yes." The servant clenched his fists and hurriedly ran to the kitchen.

After a while, he really ran over with another tea set.

Seeing the tea set brought by the servant, Zhang Xiaobao hurriedly ran over, and after carefully observing it for a long time, he hugged his fists and said to Gongsun Jian: "My lord, this is what we usually use." ”

However, then he wondered: "But when did the murderer change the tea set?" ”

Hearing this, Gongsun Jian almost scolded him for being a stupid donkey.

It's just a change of tea set, so why don't you use it for a few days?

When you boil water, you can change the tea set by the way!

Fortunately, Zhang Chenglin on the side didn't care about his stupidity, he looked at Zhang Xiaobao with a smile.

"Xiaobao, it won't take long for a different set of tea sets to work, just a moment."

"Young master, I mean there is dust on this tea set, it was obviously changed a few days ago." As he spoke, Zhang Xiaobao also took out a teacup and wiped the dust on it to show Zhang Chenglin.

Hearing his explanation, although Gongsun Jian was embarrassed, he showed an expression of appreciation to Zhang Xiaobao on his face.

It seems to be saying that he is very attentive to observation.

Zhang Xiaobao over there naturally didn't know that Gongsun Jian was scolding him in his heart just now, and at this time, he was very happy when he saw the county magistrate's appreciative smile at him.

"But, my lord..."Zhang Chenglin over there just wanted to ask another question, but Zhao Yang directly interrupted him.

Because everyone present understood what Zhang Chenglin wanted to ask, after all, Gu Qing had already gone to call the shopkeeper Yang, except for him, all the people present were people with normal brains.

"My lord, although these teacups have been soaked in Tripterygium wilfordii, if you only use these teacups for a few days, not only will they not be poisoned, but they will also have some benefits for the body." Zhao Yang said respectfully to Gongsun Jian.
