Episode 21 recap: Blue is the reincarnation of the Enchantress.

When Han Ye saw Blue with red eyes, he immediately ordered someone to inform Prince Ye of the situation, while he stayed behind to stop Blue. However, Han Ye was surprised to find that Blue's current strength was exceptionally strong and beyond his ability to contend with. A Jiu, who had formed a spiritual bond with Blue, felt the intense pain from the energy within Blue's body, even more agonizing than being burned. A Jiu struggled to save Blue.

Upon seeing A Jiu appear, Blue heard a voice in her heart telling her that it was because of A Jiu that the Herb Clan was destroyed. Blue immediately pulled A Jiu closer and, seeing A Jiu's pained expression, A Jiu apologized to Blue. This reminded Blue of the happy times they had together, and for a moment, she softened and asked A Jiu why she had treated her this way.

Yuhu saw that A Jiu was in trouble and unexpectedly rescued her from Blue's grasp. At the same time, Yuhu noticed the flame mark on Blue's forehead and speculated that Blue was the reincarnation of the Enchantress, and that all three realms were facing a great calamity. Prince Ye had been observing the situation for a long time and was excited by Blue's tremendous power. He came up with a clever plan to use Blue's help to seize the throne. He personally invited Blue to have a conversation.

Blue expressed concern for her fellow members of the Herb Clan, and Prince Ye offered to save their lives as a condition for Blue's assistance. Blue believed that her current strength was more than enough to kill Prince Ye and save the Herb Clan, but she had reservations. She worried that conflicts between mortals and spirits would persist, and this problem would not be thoroughly resolved. Prince Ye seized upon this and promised that once he ascended the throne, he would decree peace between mortals and the Herb Clan.
