Strange. You should be able to engage him in a fight the 2nd time around. For the 'Fei Hu Wai Zhuan' story, here is what I did.Originally Posted by Feng Qingyang
Step 1: Fought with that Ji Du Wang guy. After I won, he told me to take whatever I want from his house. I got the 2 pages of Hu Family Sabre Manual.
Step 2: Gave that 2 pages to Hu Fei. Asked Hu Fei to join.
Step 3: Went to find Miao Ren Feng and saved him from Shen Long Jiao.
Step 4: Hu Fei talked to him (about his father's death and all that).
Step 5: Went to find Ji Du Wang, fought with him (I think Hu Fei is a must in this battle). I forgot whether the guy will die or not after we won, but I got a potted plant.
Step 6: Brought plotted plant to Medicine King (that place surrounded by read trees near the main character's house). You figure yourself how to get in .
Step 7: Met Cheng Ling Su there. Gave her the potted plant to make the antidote. Asked her to join (she will only join if Hu Fei is in the group).
Step 8: Went back to MRF and gave him the antidote. Hu Fei fought with MRF. Hu Fei won. Got 'Fei Hu Wai Zhuan'.
