When Mrs. Huang saw the large basin of unwashed cups, plates, and bowls, she was both amused and exasperated.

"Dr. Gu, thank you for your trouble. Shanwazi, when you were serving water and dishes to the guests, did you notice anything unusual?"

Huang asked casually, but Shanwazi's greatest strength was his good memory.

He began by recounting everything from the two guests sitting down to placing their order, bringing water, and serving the dishes, including the two water glasses Li Er used.

"Oh, you two gentlemen haven't drunk any wine, so why do you need two water cups?" Huang asked curiously.

This made Li Er angry.

"Who knows? I've always felt that the food at your house is clean, but today when I came back from the outhouse, the water I drank tasted like it had flour in it."

It was sticky and gritty. I had to ask the waiter to change the cup.

Madam Huang frowned. "Shanwazi, is the cup you gave this guest clean?"

Shanwazi stared wide-eyed, as if Huang was questioning his stupidity, and pouted.

"Grandma Huang, what I took was definitely clean."

All the tableware we use for our guests has been thoroughly cleaned and boiled at high temperature, so how could it possibly be dirty?

Besides, these two guests arrived very early; they were among the first group of customers, so there's absolutely no chance of them taking the wrong item.

Madam Huang frowned. "Esteemed guests, have you ever left your seats?"

Wang Wu shook his head, while Li Er nodded.

Huang began to inquire.

Wang Wu then remembered the incident where a madwoman came to the outhouse when Li Er went there and described it to him.

"Since that woman is sitting in Mr. Li's seat, Mr. Wang, have you noticed what she did, such as what she was holding or what outrageous thing she did?"

Huang pressed for an answer.

Wang Wu recalled it carefully again.

"I was terrified by her. I had never seen such a frightening woman before. At the time, I only noticed her eyes."

As for what she did, well, she sat in Brother Li's seat, raised her right hand, and the position of her hand..."

Wang Wu repeated the woman's actions. He was completely stunned.

At this moment, Dr. Gu also found the cup from which the murky liquid had been drawn among the dirty dishes.

After Dr. Gu's examination, it was confirmed to be croton powder.

It is now confirmed that someone deliberately poisoned Li Er.

"Esteemed guests, may I ask if you have offended anyone?"

The two looked at each other, both saying they had never heard of it.

Huang believes there are two possibilities for how Li Er could have been poisoned in public.

One possibility is that Li Er offended someone, and another is that they came for his family's business.

This kind of thing cannot be tolerated.

"Esteemed guests, perhaps we should do this: what happened today is too strange. Why don't we report it to the authorities?"

That way, justice can be served for you two as soon as possible.

The two agreed, went to the backyard to fetch a carriage, and, carrying the evidence "cup," along with witnesses Doctor Gu and Shanwazi, rode in the carriage to the county government office.

Upon arriving at the county government office and explaining the situation, the suspect turned out to be the woman with dark circles under her eyes. And it was yet another heinous case of poisoning.

Fortunately, the murderer wasn't vicious enough; if he had used rat poison or something, Li Er would be dead by now.

There were specialized painters in the county government office.

Based on Wang Wu's description, a rough sketch of the woman with dark circles under her eyes was drawn.

Although it's a bit abstract, Huang Shi looks like a person.

Since it was someone she was familiar with, it must have been someone she had offended. Huang pondered the recent events without showing any emotion.

Suddenly, Zhang Baosheng's face came into view.

Looking at the person in the portrait again, it can be basically confirmed that it is Zhang Baosheng's mother, Zhang Qiushi.

"Sir, it seems that I know who the murderer is."

So Huang then recounted in detail the feud between her family and the Zhang family, as well as the recent events that had occurred.

There was no embellishment; the scene was reproduced exactly as it was.

Lord Qiu felt that his abilities were being questioned.

It is unheard of for something so disgusting to happen under one's own jurisdiction.

Now that we know who committed the crime, we summon the clerk and have him search for Zhang Baosheng's family.

"Zhang Qiang, take a team of men to Qingshui Bay to capture the person, and bring the whole family with you."

Li Guang, take a team to Wufang Town to search, especially the inns.

Zhang Qiushi probably wasn't sure when she would succeed before committing the crime.

That means we must prepare for two scenarios: one is to return to Clearwater Bay before dark, and the other is to find an inn to stay in first.

Lord Qiu gave the instructions.

To assist in solving the case, the group followed the constables back to Wufang Town.

Li Er and Doctor Gu were sent home. Wang Wu and Huang Shi both knew Zhang Qiu Shi, so they followed the officials from inn to inquire about her.

By the time they found the inn where Zhang Qiu was staying, it was already late at night.

Thinking she had done everything perfectly, Zhang Qiu was having a wonderful dream in the inn. In her dream, her son held a high position and had obtained an imperial title for her.

Surrounded by a group of maids and servants, kneeling before him was that little wretch Zhao Qingyan, who was disobedient and being slapped by the old woman.

He was so smug.

With a "bang," the door was kicked open, waking Zhang Qiushi from her dream.

She was still stuck in the mindset of being a high and mighty old lady, unable to break free.

"Where did this lackey come from, so ignorant of the rules? Guards, drag him away and beat him to death with sticks!"

"Holy crap, this woman is really crazy. Someone, bring a basin of cold water to wake her up."

Li Guang gave the instructions.

There's no need to trouble the officials with such matters.

Huang saw a basin of water for washing her face by the window, went over, picked it up, and poured it over Zhang Qiu's head.

Stimulated by the cold water, Zhang Qiushi fully regained her senses. Looking at the room full of officials and the Huang family and Wang Wu standing beside them, she trembled with fear.

Before she could even cry out for justice, Li Guang waved his hand, and officials came up and tied Zhang Qiushi up.

Zhang Qiushi, who was already numb, had lost all her previous fierce and stern demeanor. She urinated, sitting on the ground and urinating.

The officers, suppressing their disgust, dragged Zhang Qiushi away, one on each side.

If Zhang Qiushi hadn't been so frightened that she wet herself, she might have been treated like a passenger in a carriage, but now she's surrounded by such a pungent smell.

Hmph, he was "cruelly" tied to the side of the carriage at the back by the officials.

It's only about ten centimeters wide, with the ends fixed, and if you're not careful in the middle, it might dangle in mid-air.

For the sake of her life, Zhang Qiu kept her body upright the whole way.

Upon arriving at the county government office, he was immediately thrown into prison.

In my drowsy state, I seemed to hear the voices of my husband and son.

"How could that be? The father and son must be resting at home."

"Damn you, Huang! How dare you throw water on me! When my son passes the imperial examination, I will grind your entire family to dust!"

Zhang Qiushi drifted off to sleep in this daze.
