"Who are you" the middle-aged man asked in a cold voice.,When Yun Yan heard this, her face was full of dejection. The usually aloof expression on her face was replaced with a pleading look as she gazed at Hu Yang, "Then... can you try to contact him I'm really anxious, as long as Doctor Hu can save my grandfather, we can agree to any condition.",Just at this moment, Yun Yanran received a call. After saying a few words, her face was full of grief, "Uncle Lu, please send me back as soon as possible. My grandfather can no longer breathe on his own and can only rely on a ventilator to maintain his life. I... want to see him for one last time."。
