Spoiler Alert
A Sacrifice and a Confession
The episode kicks off right where we left it. Wu Zhen and Mei Zhuyu are stuck in Pei Jiya's rock trap. The Wordless Book is losing its mind, trying to get Pei Jiya to tell them how to break the spell.
But Pei Jiya just laughs. He admits the whole thing was designed to kill Mei Zhuyu. He also says that even if they break the formation, it needs a blood sacrifice. Someone has to die. The rocks start closing in. With just moments left, Mei Zhuyu finally tells Wu Zhen the truth. He says he fell for her way back in the sea of flowers. He just never said anything because he was afraid his own problems would bring her down.
Then he shoves her out of the trap. He falls into a dark abyss and gets swallowed by black fog. Wu Zhen is left screaming his name. It's a gut punch.
The Tables Turn
Just as the Wordless Book is about to end Pei Jiya, a flash of light shoots out from the abyss. It's Mei Zhuyu. He figured out the trap's weak point from the inside and used it to shoot a magical blast right through Pei Jiya's eye.
Mei Zhuyu isn't totally safe, though. He starts turning to stone. But then his spiritual power flares up and completely shatters the trap around him. He stumbles out, and Wu Zhen just runs and throws her arms around him. They have a real, proper hug.
The Aftermath
Confronting the Traitor
Back on the boat, Pei Jiya is bleeding everywhere from his eye. He confesses he did it all because he was jealous of Mei Zhuyu. Wu Zhen is having none of it. She lays out exactly how she figured him out. She knew something was up ever since a servant at the Ruyi Lounge used a weird incense that made her mistake Pei Jiya for Mei Zhuyu.Then Hu Zhu told her that Pei Jiya was spotted lurking around the ink room. All the little pieces finally clicked into place.
Pei Jiya tries to argue he did it all for her love. Wu Zhen calls him out for being a monster who left them to die.
A Merciful Banishment
The evil spell starts to backfire on Pei Jiya, causing him agonizing pain in his ruined eye. Mei Zhuyu, being the good guy he is, actually helps him and removes the arrow. Seeing this, Wu Zhen comes up with a clever solution. She banishes Pei Jiya to the distant Kunzhou province, telling everyone it's for "medical treatment." This gets him out of their lives for good without causing a huge political scandal.
