Hidden away from the outside world, on the top of Wuxiang Mountain, there is an ancient sect called "Shimen". There are no masters and disciples in the sect, only "fellow disciples". Twelve men and women of different ages, whose identities are mysterious, gathered here due to the enlightenment of different "guides". They may be good at dancing and adjusting spirits, or they may know the medical skills of life and death, or they may be good at manipulating power and political situations, or they may be able to transform into thousands of faces... In Shimen, they are comrades who have forgotten their past lives and only cultivate the "Linglong Heart Seal".
However, the eternal tranquility was finally broken. A chaotic force called "Obscurity" began to erode the destiny of the world, and even the pure land of Shimen was not spared. The elders of the sect used unpredictable power to force the twelve people down the mountain and ordered them to join the world and face the catastrophe that was coming. Before leaving the mountain, a "tongchen star array" engraved into their souls became the only and unbreakable connection between them.
Stepping into the world, the pattern of the four countries is complicated and undercurrents are surging. They originally wanted to observe in secret and follow the trend, but gradually discovered that their lost memories were closely related to their noble but heavy life experiences - they were an exiled princess, a deposed prince, an anonymous saint, and an unjust general... And when the dark shadows became aware of their existence, a huge net was quietly woven against the twelve people.
They must find their own strength and memory in a crisis-ridden chess game, and grow in resonance and bond with each other. From strangers who were forced to join forces, to Tongchenyu, who shares life and death, they face not only the disputes and dark conspiracies among the four countries, but also the final choice concerning the order of heaven and earth, and their own path. This is a grand epic that begins with the right people and ends with the hearts of the people.
