※This article contains spoilers. In the SBS TV series "Ghost Palace" EP11 (viewership rating: 8.7%), Gangcholi (Yuk Seong Jae) and Yoli (Kim Ji Yeon)
The film depicts how the King (Kim JiHun) and the Demon King (Kim JiHun) get closer to discovering the true identity of the Demon King. Taking advantage of the opportunity that the Demon King possessed Poongsan (Kim SangHo) escaped, Gangcholi saves Yoli and saves the shrine.
Gangcheol-ri, Yo-ri and the King now know who Poongsan really is, but he has already disappeared. Yo-ri remembers that Poongsan called her "bait" when he disappeared, and
The king visited the temple of Pungsan to vent his frustration at the demon who was pushing him into endless fear. Gangcholi also possessed the demon,
After pondering over Poongsan's words and actions, he came to the conclusion that the demon must know him. Gangcholi is a scientist who eats the bad nobles in order to ascend to heaven.
Gangcholi tried to persuade Yo-ri, saying, "It's God's fault, so don't get angry," but Yo-ri replied, "When God kills a person, it's God's punishment, but when a person kills a person, it's murder."
He expressed his disappointment in Gangcholi, who was involved in the life and death of humans in Gab's (Yuk Seong Jae's 2nd role) body. When Yeori worried about Gab, Gangcholi couldn't sleep at night because of jealousy.
Bibi's hatred towards Yori, which was already a thorn in her side, grew even stronger. Furthermore, in order for Ganchori to eliminate the Hassaku Oni, all of the luminous pillars in his body must be consumed.
Bibi was shocked to find out the truth. When Poongsan's true identity was revealed, Bong-in (Son Byung-ho) was desperate to clean up the mess. Bong-in told the king that the Queen Mother (Ha) was standing behind Poongsan.
However, the King was suspicious of Bong-in's attitude and visited the Queen Dowager to find out who had introduced Poong-san to him and revealed his misdeeds. The Queen Dowager replied that she was the one who had introduced him to the King.
She was troubled by the realization that she had been a foolish mother who had sacrificed her son, Prince Yeongin (Kim Seong-bin), to the Yasaka Demon.
