She was put on the cracks in the world by two men she shouldn't love.
Bai Ze, the Kunlun beast in charge of the laws of heaven, gave her knowledge and protected her. Wen Renyi, the orphan of Gonggong who bore a blood feud, laid down his life for her and offered his sincerity. One part is a silent guardian who abides by heaven's rules, and the other part is a burning sincerity that burns everything.
And she, Yunzhi, is just a herb collector in the mountains and fields who can listen to the pain of all things, but she has become the "key" connecting the worlds of two mortal enemies. To love him is to betray the order, to love him is to agree with original sin, to love both is to shake the world.
When corrosive energy engulfs the mountains and seas, ancient conspiracies emerge. Before healing the world, she must first heal this deep love that cannot be tolerated in the world - between law and sincerity, protection and destruction, the three worlds are torn apart and reshaped.
