The Founder of Diabolism

Same Boat (1x9)

:

With the beast angered, the Wen sect escapes from the cave and blocks the entrance, preventing anyone else from leaving. Lan Wangji points out that there is another opening as there are maple leaves despite the lack of its trees. As the beast returns to sleep, Wei Wuxian and Jiang Cheng are appointed to dive into the water to search for the way out. However, Wei Wuxian accidentally awakens the beast while Jiang Cheng emerges with good news. Wei Wuxian stays to hold off the beast while the others can have a chance to escape. But Su She accidentally shoots him in the shoulder with an arrow, causing Wei Wuxian's powers to weaken faster. While everyone have escaped, Lan Wangji stays to help Wei Wuxian. The two fights off the beasts but the cave is now blocked once again, so they tend to each other wounds and Lan Wangji tearfully confesses about his worry for his family. They make a deal to wait for three days before engaging to fight the Tortoise of Carnage by themselves. They eventually attempt to fight the beast with the Lan sect's Killer String Technique. When Wei Wuxian dives in to lure the beast, he is drawn to a mysterious sword hiding deep within that is full of resentful energy.
