Synopsis · Yún Xiāo and Cán Yún are revealed to be allies summoned by Guǐ Niǎo to join Fěi and a reluctant Bù Huàn as they journey to the Seven Sins Tower in the Demon Spine Mountains where the Xuán Guǐ Zōng dwell. Guǐ Niǎo explains that in order to get past the barrier surrounding the mountains and reach the tower, they must overcome three different obstacles, one of which requires the assistance of a demon necromancer named Xíng Hài, who resides in the Night Devil Forest. The next day, the group heads into the forest to seek out Hài, who believes them to be trespassers and attacks them with an army of zombies, which Fěi and Cán Yún fend off while the other three press forward.
