It's late and Mr. Qin isn't there yet. He's got a cold and won't be able to attend to his nephew. He tells his son-in-law to go check on his father. He says that he'll send additional men to guard the mansion if there's anything wrong. Mr. . , who's glad to see his dad, says he's arranged for the best doctor to come and treat him. He also says that if his dad doesn't wake up soon, he will be cured. He then says that his dad's going to need the help of "the big man" . The big man is going to have to help him with the potion. He explains that the potion has to be mixed with his "soul power" , which is higher than the "earth spirit five heavens" : the higher the level of the earth's power, the greater the healing power of the potion . So, if you're going to use the potion to purify the "yin evil spirit," you've got to use "the soul power" to do it, too, because it's higher than "the earth spirit five heaven" ! So, the big man has to use both of his powers to do the job. He asks if Mr. Quin wants to go with him, and he says he can't go, because he'd rather stay and watch "the brat" than go to the doctor and cure his dad. He goes on to say that apart from his father and uncle , he has earned the "greatest credit" in the "qin family industry"
