Qinglan Ferry is the ferry at the edge of the world of cultivation. Its left hand is next to the smoke of the mortal world, and its right hand is close to the mist of the spiritual world. Most of the people coming and going are casual cultivators and demon spirits. Occasionally, a large number of sect disciples pass by, and most of them are hiding from the world or looking for things. Su Wanqing opened a "Wangyou Tea House" at the ferry end, guarding a small shop, making tea and selling wine. She seemed indifferent and casual, but there was an indelible sadness in her eyes - she lost a memory, and only remembered a jade button engraved with the word "scape", and a vague sentence "Wait for me at Qinglan Ferry". For hundreds of years, she restrained her cultivation, concealed her identity, and became just an ordinary teahouse owner. She didn't dare to delve into the past, but she couldn't help but look forward to it. Until one day, Mo Jingyuan, who was seriously injured, was carried into the tea room. An identical jade button with the word "scape" hung on his waist. When he woke up, his eyes were wary, but when he saw Su Wanqing, a trace of imperceptible familiarity flashed in his eyes. With Mo Jingyuan's stay, the peace of Qinglandu was broken. Xuanyin Pavilion who was chasing him and various sects who coveted the secret treasure at the bottom of the ferry came one after another. Su Wanqing was forced to expose his cultivation. The forgotten past, hidden love, and dust-laden conspiracies gradually surfaced. While she is struggling with the dilemma of "whether to retrieve her memory", she is repeatedly pulled between protecting Mo Jingyuan and maintaining her own stability. What is hidden at the bottom of Qinglan Crossing is not only the secret of the world of cultivation, but also her and Mo Jingyuan's old love that spanned life and death and was deliberately erased. The road ahead is long and murderous. Every choice she makes is related to the truth of the past and the future of the two of them.
