"Gu Family Book" Lee Seung Gi begins to train so that he can kill his father Choi Jin Hyuk who has returned as an evil spirit

June 11, the 20th episode of the MBC drama "Gu Family Book" featured Choi Kang Chi (Lee Seung Gi) fighting against Dam Pyung Joon (Jo Sung Ha) in order to train for the fight against his father Goo Wol Ryung (Choi Jin Hyuk).

Meanwhile, Dam Yeo Wool (Bae Suzy) speaks to Ja Hong Myung (Yoon Se Ah). She says, "Can't you live as Kang Chi's mother from now on? Can't you heal the scars he has? Can't you give him everything he lost?"

At the same time at a different location, Dam Pyung Joon tells Choi Kang Chi, "Take off your bracelet and attack me with everything you've got." Choi Kang Chi hesitates when Dam Pyung Joon takes out his sword at him.

Gon (Sung Joon) watches the two men and remembers the moment Dam Pyung Joon had told him, "This is the only thing I can do for a child whose father has been killed in my hands. I am the one who turned his father into an evil spirit. In order to teach a student, the most a teacher can do is to risk his life for his student."

Dam Pyung Joon had decided to dedicate everything to prepare Choi Kang Chi for a fight against Goo Wol Ryung since he is the only one who has a chance to killing him for good.
