"It seems that our country's doctors have a successor!" When a deep voice came from behind her, Jian Xing'er turned around and realized that the person who spoke was an old man. He didn't come by himself. There was a cute little boy standing behind him. Jian Xing'er felt that this old man looked a little familiar, but she couldn't remember where she had seen him before. She simply stopped thinking about it and smiled at the old man before turning to leave. "Please wait! I want to ask you for a favor!" When the old man suddenly stopped Jian Xing'er, Jian Xing'er turned around and said in confusion, "How can I help you?" The old man explained to Jian Xing'er with a solemn expression, "I want to ask you to treat my grandson! My grandson has had a very strange illness since the day he was born." With that, the old man pushed the little boy in front of Jian Xing'er and begged, "With your ability, you can definitely save my grandson's life."
