After Wei WuXian meets a dead end while running away from Fairy, he calls out for Lan WangJi's help. The latter arrives to stop Jin Ling from teasing him further and Jin Ling leaves with his dog. Wei WuXian then asks the merchant about any strange incidents and learns the existence of a XingLu Ridge that eats souls. When he then asks why the Nie Sect has done nothing to stop this, the merchant says that the current sect leader Nie HuaiSang is incapable of doing anything. Wei WuXian and Lan WangJi then goes to find the tower. There, they keep hearing Fairy's barking but Jin Ling is not in sight. They then enter the tower through a broken hole and Wei WuXian gets frequently bothered by the spiritual energy inside. Wei WuXian then uses the Compass of Evil to find Jin Ling. When they arrive at the coffin area, they are surprised to find that only swords are inside the coffins. Lan WangJi then uses Inquiry to ask for Jin Ling's whereabouts. They successfully retrieve him from inside the wall and splits up outside. Lan WangJi goes to chase after the mysterious person while Wei WuXian brings Jin Ling to rest in an inn. However, when Jin Ling wakes, he runs away and Wei WuXian gets caught by Jiang Cheng while chasing for him. Wei WuXian's identity is finally revealed to Jiang Cheng, and the two have another heated argument about the past. Jin Ling then lies to Jiang Cheng to save Wei WuXian and justifies that it's because he doesn't believe Wei WuXian is the real deal. Wei WuXian then knocks Jin Ling out to absorb the curse marks from Jin Ling onto himself. (Source: Wikipedia)
