Behind the neon lights of bustling cities, lies and illusions follow. Ji Zhen, a young reporter, possesses a magical pen that can write the truth. Wherever the pen touches, falsehoods will not escape. During an investigation, she met Jing Ling Jing Ming, the former incarnation of the Heavenly Mind Mirror, who was demoted to the mortal world for questioning the way of heaven.
The two work together to fight against the phantom that manipulates public opinion, use photo stones to record the truth, and use real pens to pierce lies. As the investigation deepens, they discover that there is a more terrifying existence hidden behind the illusion - the Tiandao Editor, a mysterious force that can tamper with the rules of the world.
Ji Zhen and Jing Ming fought on the boundary between truth and lies, rewriting the facts again and again, but at the cost of life and memory. In the gap between heaven and earth, they established the Truth Alliance to fight against the tamperers from other worlds, and finally discovered that all the worlds are just pages of the "Book of All Truths", and they themselves are the writers.
This is a legend that transcends reincarnation and protects the truth. It is also a fairy tale about courage, sacrifice and choice.
