Among the three of them, the most surprised person was Gu Pianran.
When Gu Pianran saw Bei Yutang, her heart was filled with turmoil.
How could it be her?
She is actually the person in charge of Lei's company.
Gu Pianran frowned instinctively. Ever since this woman appeared, she always felt that everything was not going well for her.
This woman must be here to jinx her.
"Fortunately, the young master of the Lei family appreciated me and entrusted me with the management of all the business of the Nan Tang Kingdom store." Bei Yutang said in a clear voice.
Lord Wang looked at her and asked, "Do you know why I asked you to come here this time?"
"It's about the recent appearance of a poisonous cream in Chang'an City."
"Now the story of your two families is being spread all over the streets. Now you can tell me, is there any way to prove your innocence?"
If they can't find the poison, then let them prove their innocence. Those who can't prove their innocence must have problems.
Officials in previous lives were not so smart. They had to go through a lot of twists and turns in their investigations before they discovered the truth.
"Okay." Gu Pianran agreed readily, showing her confidence in this matter.
Lord Wang frowned slightly when he saw Bei Yutang didn't respond, "Madam Mu, do you have any questions?"
"Sir, I just thought of a way to prove the innocence of our two families." Bei Yutang said.
"What method?" Lord Wang was very curious.
Not to mention that he was curious, Gu Fanzhi was also very curious, and Gu Pianran was more worried in her heart, worried that she really had a way to prove all this.
The three of them all looked at Bei Yutang.
"We can find six women and have them use Gu's and Lei's face creams. We can tell which brand's cream has problems by looking at the women."
Lord Wang's eyes lit up. This method was indeed good, but it would take a little too long.
Gu Fanzhi also agreed with this method.
Gu Pianran's heart skipped a beat. Although she remained calm on the surface, she was actually feeling panicky inside.
"The method is good, but it takes too long." Lord Wang pointed out the problem.
Bei Yutang said slowly, "Normally, we use facial cream once in the morning and once in the evening. If we ask six women to apply it once every three hours, this can greatly shorten the time."
"It's just one more time. How can you guarantee that they can produce the results within the time limit set by His Majesty?"
"My Lord, ever since the Lei family became involved in this incident, I've sent people to investigate the onset of these disfigured women's illnesses. This is a comparison of the time periods before and after they used our Lei family's face mask and the Gu family's face mask. I carefully inquired about their daily dosage and the dates of their illness, and roughly calculated that the latest onset of illness coincided with the final period specified by Your Majesty."
Bei Yutang took out her investigation results from her sleeve.
After the Fourth Prince and Lord Wang passed it around, they could both tell that she came well prepared.
Lord Wang agreed with this method, but he didn't dare to slam the table. He could only turn to look at the Fourth Prince and ask for his opinion, "Fourth Prince, do you think this method is feasible?"
The Fourth Prince was afraid that Gu Pianran would suffer. After all, this plan was proposed by the Lei family. Perhaps they had already come up with a countermeasure. By then, Pianran would definitely suffer, and might even be framed.
However, there is no better way to verify it so far.
After careful consideration, the Fourth Prince nodded and said, "That's it."
