The doctor tells Zeng that he will kill him if he tries to harm his wife. Zeng says he will give him a transformation, and if he cannot get it, he will destroy it. The doctor says that if he had known what would happen, he wouldn't have ended up like this. He says that he is the man who solved the formula for the drug that Zeng drank, and that his name is "yinshi chen" . He asks if Zeng is having an operation, and Zeng replies that he believes she will recover in the next day. He is impressed by the young man's talent, and says that his research has been very nice. He adds that he can sue Zeng if he wants to, but that his formula is the product of Zeng's genius, and he says that others may think Zeng carried out the experiment on himself and then went mad, but Zeng argues that they are the same person, and should be able to finish the task in three hours. He then asks Zeng where he can find the people he needs, and when Zeng asks where he is, Zeng answers that he has brought his man, who has promised to give him bowenzhou back.
