Cha Luo says she will spare Wan Mei and Chang'An if it snows on a sunny summer day. Just then, Li Si Yuan manipulates the air and snow begins to fall. Cha Luo lets them go but Chang'An is still dying from the poison. Wan Mei rushes to the apothecary to get the antidote but because she has failed her mission, they refuse to give her the antidote. Meanwhile, Yue Yang uses the gua jian grass to brew the potion that will heal Li Si Yuan's blindness. Wan Mei rushes to their residence and begs Yue Yang to give her the antidote but Yue Yang refuses and tells her she should have killed Doctor Shen if she wanted to have the antidote. Wan Mei does not give up and kneels there all night. The next day, Li Si Yuan whose eyes have healed slightly takes pity on her in his good mood and tells her that if she is willing to give her life in exchange for Chang'An's, then he will help her. She accepts but Li Si Yuan does not kill her. Instead, he tells her that if she can catch one firefly from the hot spring in 6 hours then he will save Chang'An. Yue Yang saves Chang'An's life while Wan Mei still struggles to catch one firefly. She finally realizes the fireflies are attracted to blood so she uses that to manipulate them all and guides them to Li Si Yuan who is surprised that she managed to do so. Things seemingly turn to normal but still, the other masters try to poison Wan Mei and Chang'An. (Source: Autumn carrot at MyDramaList)
