A hundred years ago, the balance between heaven and earth was out of balance, and obsession and turbidity arose in the world, and the tide returned to zero in a recurring cycle.
The black mist traps family affection and guilt, the red mist traps entangled love, and the turbid current of loess traps all living beings in mediocrity and unwillingness. Once the turbid core is formed, the whole city will fall into eternal reincarnation and be trapped in their own regrets.
Su Yan, who has returned from rebirth, has the only counter-obsession in the world. It is his innate power to cut off the past and eliminate illusions. After two lifetimes of walking alone against the tide of the apocalypse and shattering the two world-wide turbid cores, he met Lin Zhixia, a girl who was born with a pure mind and was not infected by obsession.
One person uses counter-thoughts as a blade, and the other uses clarity as a shield. The two work together to explore the source of the tide, break into the ancient view of Wangchuan that has been sealed for hundreds of years, and get a glimpse of the spring where thousands of thoughts gather underground.
The torrent of three obsessions resonates, the three-color turbid core appears, and the final end of the world comes.
In order to completely destroy the hundred-year cycle rule, Su Yan burned his soul and fell into the Abyss of Ten Thousand Thoughts, using himself to eliminate all the shackles of obsession in the world.
The tide ceases, reincarnation disappears, and there is no longer a prison in the world.
The world is peaceful every year, but only one person remains at the end of the abyss forever.
