Xiang Yue didn't know who to call and misdialed the number several times.

Old Liu stepped forward and said, "Who are you trying to call? I'll help you!"

Xiang Yue trembled, "Call... call Meng Qingqiu!"

Old Liu said, "Let's go find her directly! Calling her might alert her."

"No need!" I shook my head. "When I broke the spell just now, I found that someone had placed a restriction on him. If that person is Meng Qingqiu, she should already know."

Old Liu took the phone from Xiang Yue and turned on the speakerphone.

Xiang Yue only managed to force out a "Hello!" when Meng Qingqiu's voice came from the other end: "You already know the truth, don't you?"

Meng Qingqiu's words were like a knife falling on his head, completely severing the last hope in Xiang Yue's heart. Xiang Yue, who was already kneeling on the ground, fell backward again.

Ye Yang gently moved a step, using his knee to support Xiang Yue's back, pushing him towards the phone.

Xiang Yue roared hoarsely, "Tell me, why?"

Meng Qingqiu said calmly, "It's nothing, just to protect my own daughter. The Yun family are the heirs to the Black and White Medical Hall. As long as they are descendants of the Yun family, they must return to the Black and White Medical Hall. This is a fact that no one can change. Unless, they die outside."

"If Yun Ya dies, the Yun family's restriction will be lifted easily. The Black and White Medical Hall will have nothing to do with Yun Shang anymore. She can live a good life. It's that simple."

Meng Qingqiu said, "I know I should say 'I'm sorry' to you. Now, no matter what I say, it's just pale words. Hate me if you want! Yun Ya is doomed to die. Li Po can't save her."

Meng Qingqiu paused and said, "Yun Shang, I know you must be listening to us. You've grown up and have the ability to take care of yourself. Live well, don't mention the Yun family again, and don't look for me again. Take care!"

Meng Qingqiu hung up the phone after speaking.

Xiang Yue knelt on the ground, crying and shouting, "Mr. Li, please save Yun Ya! I'm willing to give you all my property, just asking you to take action."

I said in a deep voice, "Stand up. I don't need all your property. I've already taken what I should take as a commission. Naturally, I will handle what you want me to do well. Let's go, back to Yun Family Village."

This time, no one on the car wanted to speak. Everyone seemed to be preoccupied with their own thoughts, not wanting to open their mouths.

Finally, Ye Yang broke the silence, "Li Po, tell me, how did Meng Qingqiu switch the two people? Bloodlines can't be changed, right?"

I shook my head slightly and said, "I'm not sure about this either."

Xiang Yunshang said in a low voice, "I know Yun Ya studied medicine. She was determined to become an excellent doctor like her father. That… Meng Qingqiu is an expert in medicine. She has been teaching Yun Ya medical skills. However, I don't know what she has learned."

"So that's how it is!" I nodded slightly and said, "It seems that the Black and White Medical Hall's criteria for choosing an heir isn't bloodline, but medical skills. In other words, no matter who the Yun family passes the secret to, they can enter the Black and White Medical Hall."

Ye Yang said again, "Then what about Yun Ya's crisis?"

I glanced at Xiang Yue, "I guess the problem still lies with Meng Qingqiu."

"A few years ago, the person who suddenly found the Black and White Medical Hall seeking medical treatment. Don't you think it was strange how he came? Perhaps, Meng Qingqiu had already started planning at that time."

Ye Yang turned his head and said, "Are you saying that they are plotting to destroy the Black and White Medical Hall?"

"That's right!" I nodded and said, "That person's existence is like a gatekeeper, a revenger, killing the descendants of the Yun family, and also destroying the Black and White Medical Hall."

"That person not only wants to kill, but also wants to destroy hearts. He wants the people of the Black and White Medical Hall to break their own rules, to come out of the medical hall to treat Yun Ya. Then, he will completely destroy the Black and White Medical Hall."

"Our going to Yun Family Village again is like leading the way for that person!"

Xiang Yunshang asked in a low voice, "Do you think Yun Sheng will be in the Black and White Medical Hall?"

"Not sure yet!" I shook my head and said, "There are too many uncertain things in this mission. Yun Sheng's disappearance was before that person approached the Black and White Medical Hall. The timing is wrong."

Ye Yang suddenly said, "What if Yun Sheng's disappearance is also related to Meng Qingqiu?"

I had already thought of what Ye Yang thought of.

The first time I saw Meng Qingqiu, I suspected from her attitude that Yun Sheng's disappearance must have some connection with her, at least she was covering up part of the truth.

Now, I increasingly suspect that there is also a feud between Yun Sheng and Meng Qingqiu.

I looked at Xiang Yue, "Mr. Xiang, I have some questions I want to ask you. I don't know..."

Xiang Yue said dejectedly, "I know what you want to ask. Although this matter is not honorable, I can't care so much now."

"Just like what you found out, back then, I exhausted all my resources to save Linlin, seeking medical treatment everywhere, and finally found Yun Sheng through someone's introduction. Yun Sheng was very sympathetic to me, and in order to treat Linlin, he even arranged for our family of three to live in his house."
