Lin Yu Yan has examined the old lady's body and and pressed on her skin to find the specific points, using her natural energy, to find out where most of the poison is located. She did first aid by sticking needles into her body and dripping the blood and poison out of her.
'Wait… this poison is super easy to cure? Why can't the Medical Sect. cure it themselves?' she thought. She can see in her peripheral view some of the faces the members were making. They weren't great ones either.
A couple of the medical sect. members decided to stay and watch Lin Yu yan's process of curing the grandmother. Most of them were hostile and annoyed why a random masked woman was here to cure the grandmother.
'Who is this woman wearing a sketchy mask and what is she doing here?' thought one of them.
But a good number of them were amazed at the different way Lin Yu Yan was doing, using certain needles to extract the poison.
'At least this one is in liquid form,' thought Lin Yu Yan.
"What is it?" asked Bingwen. He decided to stay to help Lin Yu Yan since there was no one else she trusted here who has a good knowledge in medicine.
"This poison is a very slow poison. Only activates when someone with a certain sickness is around and the little boy has it. Every time he is around her, the poison slowly spreads. This poison is quite rare so the body can't fight it on it's own but can be easily removed. Only issue is that this poison has no side effects until the very last stage," said Lin Yu Yan.
"I see…"
A few moments later the herbs were brought in and Lin Yu Yan was able to make an antidote.
"Yu Yan! What's wrong!?" came in Meiying.
Lin Yu Yan explains the situation and Meiying and she starts thinking of ways to make the antidote.
"I've done most of it already here. I need you to check on Su Wen's younger brother and find a way to cure him," asked Lin Yu Yan.
"Got it," said Meiying.
"I have a request," said Su Wen. She hesitated to ask but she needed it to be clear. Lin Yu Yan, Bingwen and Meiying looked at her in confused.
"Please don't tell my brother about this. If he found out that being with my grandmother this whole time was killing her, he would be very upset," asked Quan Su Wen.
Lin Yu Yan wasn't sure if that was a good idea but she nodded.
"Let me take you to his room," said Quan Su Wen to Meiying.
Meiying and Quan Su Wen leaves the room and closes the door behind them. Lin Yu Yan can hear some of the members mouth click in disgust and some snicker in delight.
"I heard the Medical Sect. was very skilled at healing and curing poisons and injuries. How come you didn't notice the poison before?" asked Lin Yu Yan to the other members.
The members freeze not knowing what to say when they heard Lin Yu Yan say those words.
Bingwen was listening carefully while helping Lin Yu Yan lift the grandmother's head to help her drink the antidote.
"Wow, what a disappointment. To even have an outsider cure such a simple poison," said Lin Yu Yan, mockingly.
"W-well, there was no side effects so how are we supposed to know!" said one of the members falling into her trap.
"Isn't that supposed to be your job? To find other aspects of the poison?" Lin Yu Yan was very disappointed this Medical Sect. branch here was actually this stupid.
"Ugh…" the member stopped talking.
"Hmmm… I think I'll call Master Mo to look more into this matter," said Lin Yu Yan.
"Master Mo!?" the members started to panic. Lin Yu Yan didn't think they'd panic this hard.
"Please! Don't call Master Mo!" said a member, already on his knees.
"Tsk," said another.
"We were only playing, it was just a joke," said another.
After the grandmother was able to finish her drink, Lin Yu Yan stood up, grabbed the one member who said it was a joke and focused her energy on him.
"Well, I don't think you understand the meaning of 'joke'," said Lin Yu Yan glaring at him.
The man was shocked and froze up stiff. He couldn't believe this little girl actually had such a strong presence. Even though Lin Yu Yan was focusing all her energy on him, all the other members present felt it too and couldn't help to hold their breaths.
"To purposely take a life… Isn't that murder?" said Lin Yu Yan. When she said that, she smiled, very cold, so fearful.
"Wu Lang. Get every members names, find their family, and kill every one of them. As a joke of course," said Lin Yu Yan.
"Ah… Yes…" said Wu Lang. He returned with Meiying and stood in the shadows until he was needed, this time he wasn't fazed since he is used to seeing her scary side by now.
"No! Please!" said a member, begging on the ground in fear.
All the others trembled in fear and kneeled down, begging for forgiveness.
Quan Su Wen felt her aura and came in and said, "Yu Yan, Stop!"
Lin Yu Yan looked over at Quan Su Wen. "It's okay, I was just scaring them. But that is half true," said Lin Yu Yan.
"It's fine. I still need them here. Please, let them go," asked Quan Su Wen.
All the members were surprised the woman they played the prank on was actually defending them. Many looked down in shame and the others clenched their fist in frustration.
"Okay. But..." said Lin Yu Yan. She let go of the man but all the members flinched hearing her say that.
"I want to know the reasons why."
