Ruler - Master of the Mask Episode 37

While everyone was running about in confusion between two, Jo Tae-ho suggested to take off the mask. As they revealed their face, Jo Tae-ho shouted that the prince is the Chief Peddler.

But Chung-woon, the son of the chief guard of the late King appeared to defense him. Everyone falls into the confusion again. King suggested bringing Queen Mother to judge. 

Queen Mother exposed the fact that the late King was murdered by Dae Mok. 

Woo Bo testified that the prince obtained strong blood that overcomes all poison after his survival in the poison to death as a child. 

Meanwhile, Ga-eun found Lady Yongbin's jar that contains the late King's letter about the prince. 

She enters the royal court with Mae Chang and Gon's help. 

Queen Mother opened up the late King's letter to everyone, and she declared anyone who survives after the poisoned tea is the real. 

Current King Lee Sun was grabbing the tea with shaking hands. The real prince takes the cup out of him and drinks. 

As the result, the letter appears to prince's shoulder. Everyone was surprised by seeing that. 

Lee Sun mocked everyone that even if the real gets the throne, Dae Mok is the one holding everyone's life. 

The real prince revealed that Dae Mok doesn't have enough poppy pill anymore as the field was all burnt and that he made a hit list. 

Queen Mother says the real prince is now their only hope and that we must accept him as new King and find a way to save their life. 

The fake cursed that everyone will die eventually without finding the antidote. Ga-eun looks at him in tears.
