An adventure inspired by a nightmare. Because Wen Yirou lost her amulet, the tourmaline pendant, she was haunted by evil spirits and coerced her into establishing a life-and-death relationship, and escorted her back to Huangquanyuan at his request. The evil spirits took away the lifespans of Wen Yirou's three best friends as the carrier of their spiritual power. The difficulties and obstacles they faced along the way were just the knots in Wen Yirou's heart.
