Dad, open the door. I'll bring your mistress back for you.

"I know, it's oil." Shen Chuning suddenly shouted as she looked at the oily sheen on Aunt Gui's face.

"How long are you going to make trouble?" asked Old Lady Shen.

"That's right, sister. The court doctor has come to see me. You asked for water, and I added it. What else do you want? Do you want to invite the imperial physician?"

Shen Jingwan knelt down in front of Old Madam Shen again after she finished speaking. "Grandmother, as the saying goes, family disgrace should not be made public. Sister is doing this to let the world know that there is discord among us sisters in the Shen family. Wan'er no longer wants Wanbaoxuan in your hands, and I also don't want the shop that Grandmother said I would reward you with. I only ask that you stop now."

"Sister, if you have any dissatisfaction, you can tell Wan'er in private. Grandma will be so sad if you do this." Shen Jingwan actually started crying as she said this.

"If there is no problem, what are you afraid of?" Shen Chuning stared at Shen Jingwan and asked.

"How could Sister think of Wan'er like this?"

Doctor Chen, the court physician, felt that as an outsider, he should not stay in Songhe Hall any longer, so he left a few silver needles and said goodbye, saying that he had something to do.

When Manager Xu of Wanbaoxuan and Manager Zhang of Huarong Pavilion saw Doctor Chen leave, they also stood up and said goodbye.

Birui took a small dish of oil from the small kitchen of Songhetang and handed it to Shen Chuning.

"Grandma, this is the last time. If there is still no problem, I will admit defeat." After Shen Chuning said this, she poured the oil directly into the jar of rouge closest to her.

Birui noticed Shen Chuning's actions, took a silver needle from the table and handed it to Shen Chuning. Shen Chuning directly used the silver needle to stir the rouge in the jar.

Before it was completely stirred, the tip of the silver needle had already turned black.

Shen Chuning raised the silver needle and said, "Grandma, look."

Nanny Gui supported Madam Shen and walked quickly to the table. She picked up the silver needle, looked at it carefully, and turned to wait for Shen Jingwan.

"Grandma, grandma, there's a problem... It's the oil... There's a problem with the oil..." Shen Jingwan quickly explained.

Madam Shen said to Nanny Gui, "Go and fetch the oil yourself."

This time, Aunt Gui brought back a can of oil and poured it into a small dish first.

Shen Chuning took another

She tried the silver needle in a small dish first, then picked up the shiny silver needle and handed it to Old Madam Shen, "Grandma, there's no problem with the oil."

Then he poured the oil into a jar of incense powder and stirred it with the silver needle. The silver needle turned black at a speed visible to the naked eye.

Shen Chuning breathed a sigh of relief. She finally figured out the key point at the last moment.

Old Madam Shen's face turned as black as the bottom of a pot. She wrapped the jar of perfume powder in a handkerchief and threw it in front of Shen Jingwan, "Shen Jingwan, did you really add arsenic in it?"

Shen Jingwan raised her head and said, "As long as the dosage is controlled, arsenic can whiten your skin. I have actually earned money for the Shen family. I have done nothing wrong."

"You...you..." Old Madam Shen was so angry that her whole body was shaking.

Shen Chuning wet her handkerchief and brought it to Old Madam Shen, "Grandma, you must have used Huarong Pavilion's things quite often. Please wipe your face first."

Old Madam Shen widened her eyes and quickly took the handkerchief to wipe her face.

"Ah Gui, silver needle."

Old Madam Shen tremblingly took a new silver needle from Nanny Gui, wrapped it in the handkerchief she had used to wipe her face, and rubbed it.

He then opened the handkerchief and saw the blackened silver needle. His legs went weak and he took two steps back. Only with the support of Aunt Gui did he avoid falling to the ground.

"Shen Jingwan, I believe I have treated you well, why do you want to harm me like this?" Old Madam Shen scolded.

"Grandma, didn't you praise the skin care cream made by Wan'er for its effectiveness? Didn't the eldest aunt and the second aunt also praise you for looking younger? Although arsenic is a little bit toxic, it doesn't prevent it from being really effective." Shen Jingwan said, pulling on the hem of Mrs. Shen's clothes.

Madam Shen waved her hand, and Shen Jingwan fell to the ground. "A little bit of poison? Do you know that this arsenic can be fatal if used improperly?"

"Anyone who talks about toxicity without considering the dosage is a hooligan. Europeans even take small doses of arsenic regularly to whiten their skin. What's wrong with me just being a little miserable in rouge and powder?" Shen Jingwan defended.

Shen Chuning and Nanny Gui helped Madam Shen sit on the Luohan bed. "What's wrong? I don't know who the Europeans you're talking about are. I just know that if this continues, our Shen family will be finished."

"Sister, you are exaggerating. You are just jealous of me. Nothing has happened in the past six months. What I do will end the Shen family." Shen Jingwan said with her neck stiff.

"Am I exaggerating? Just because nothing happened in the past six months doesn't mean there won't be any in the future. Besides, is there really nothing? What about the rashes that appear on the faces of those who stopped using Huarong Pavilion's rouge and powder?"

"Second brother, what do you think we should do now?" Old Madam Shen asked tremblingly.

Knowing that her shop was selling poisonous rouge and powder, Mrs. Shen was completely at a loss as to what to do. She could only seek help from her second daughter-in-law, who came from a merchant family.

Madam Shen Er said carefully: "Mother, under the current circumstances, I am afraid that Huarong Pavilion cannot be saved. Let's close it first."

Madam Shen nodded and said, "Yes, yes, we can't sell it anymore. Ah Gui, go quickly and tell someone to close Huarong Pavilion first."

Nanny Gui got the order and ran out of Songhe Hall. Shen Jingwan grabbed Nanny Gui and said to Old Madam Shen, "Grandma, we can't close Huarong Pavilion. I just developed a batch of whitening pills and haven't started selling them yet. Once these whitening pills start selling, it will bring in hundreds of thousands of taels of silver."

When Shen Chuning heard about whitening pills, she thought of what Shen Jingwan had just said about Europeans eating arsenic.

"You wouldn't add arsenic to the whitening pills, would you?" Shen Chuning asked.

"So what if I added some? It's just a little bit. The maids in my Purple Bamboo Courtyard have all eaten it. It won't kill anyone."

"Evil daughter! Evil daughter!" Old Madam Shen slammed the table loudly and said excitedly.

"Shen Jingwan, you are taking human life lightly by testing medicine on maids." Madam Shen Er said angrily.

"Miss...Miss..." Fuzi was so scared that she sat down on the ground, shaking constantly, with cold sweat pouring out of her body.

Miss Wan prepared a pill and gave one to each maid in the yard every day, saying that taking it would make them more beautiful. At first, she didn't dare to take it, but when she saw that other maids became whiter after taking it and didn't feel any discomfort, she ate it. It turned out that the pill was mixed with arsenic.

Shen Chuning stared at Shen Jingwan and asked, "Since you said it wouldn't hurt if you ate it, did you eat it yourself?"

"I... I am naturally beautiful, so naturally I don't need to eat those things." Shen Jingwan argued cunningly.

"So you know that although this thing does have whitening effects, it is harmful to the body after taking it?"

"No...no harm."

There was nothing Old Lady Shen couldn't understand at this time. Shen Jingwan was deliberately trying to kill the Shen family. "Agui, why don't you go and tell someone to close the shop?"

"Grandma, Huarong Pavilion's rouge and powder are selling so well, and Shen Jingwan is using some kind of hunger marketing. Many ladies keep three or five cans of them at home as backup. If we just close the shop, there might be problems." Shen Chuning said solemnly.
