Ep. 9: Wei Wuxian and Jiang Cheng search for an exit while Lan Wangji assists in the escape.

The Wen sect blocks the cave after angering a beast, trapping everyone inside. Lan Wangji identifies a hidden tunnel connected to a pond where maple leaves are found. Wei Wuxian and Jiang Cheng dive in to locate the exit, but Wei Wuxian accidentally wakes the creature. He stays behind to distract it with a flame array while others flee. Su She accidentally shoots Wei Wuxian, weakening him and attracting the beast with blood. Lan Wangji rescues Wei Wuxian, but the tunnel collapses, leaving escapees vulnerable to Wen attackers. After resting for three days, they confront the Tortoise of Carnage using the Killer String Technique. Wei Wuxian lures the beast into the water, where he is drawn to a resentful sword and swallowed. Together with Lan Wangji, they kill the monster, but Wei Wuxian sinks unconscious as the sword disappears.
