"Gu Family Book" Lee Seung Gi uses his wit to retrieve the stolen silver from Lee Sung Jae.

May 7, an episode of the MBC drama "Gu Family Book" featured Choi Kang Chi (Lee Seung Gi) retrieving Park Moo Sol's (Uhm Hyo Sup) silver that has been taken by Jo Kwan Woong (Lee Sung Jae).

During this episode, Choi Kang Chi hides inside of the secret safe with Dam Yeo Wool (Bae Suzy) in order to get Park Moo Sol's silver. However, they get locked inside because of Jo Kwan Woong's men who are trying to capture them. Inside the secret safe, they find Park Moo Sol's silver.

Jo Kwan Woong eventually learns about the location of the silver and Choi Kang Chi is on the risk of losing it. Choi Kang Chi hides the silver but pretends to hand it over to a soldier along with his meal.

Choi Kang Chi knows that he needs to make sure the silver does not get into the wrong hands since it is worth enough to build 12 ships for the army.

Later when Choi Kang Chi proudly returns with the silver, a man questions him about how he kept the silver in his possession. Choi Kang Chi answers, "Didn't you know? I'm not human."
