Dr. Lichanghe, director of the city general hospital, comes to apologize to Mr. Yang. He tells him that he is the only person in the world who can save his son. He says that he will restore his son's hematopoietic function in half an hour. The doctor says that the pill he is using will change his bone marrow completely, and the blood inside his body will also be regenerated. He also says that this pill is made from seven herbs, and combining it with his dragon-revitalizing method, it will regulate his blood and qi. After this, the blood indices return to normal. He thanks the doctor and says that if his son is released from the hospital, his blood results will be normal for three days. The grandfather asks his grandson where he has been. He wants to know if he has visited southeast Asia before becoming ill, or has he been to a strange place. He asks him to tell him everything he knows.
