Why Should a Little Devil Be in Charge of Tianheng?

[Urban Superpower + Decisive Killing + Revenge] My name is Gu Yan. I died at the age of fifteen. I was supposed to become a part of heaven, but by some strange combination of circumstances, I became a lonely soul in the world. My best friend and teacher Wei Chou is also a lonely soul, but he is different from me. He tried to reverse destiny, but in the end he became a pendant on my chest. He made me see the tragedy of destiny being irreversible, and he also made me a guide to the destiny of the world. The Crouching Tiger, Hidden Dragon in Lanxin City that I protect has been in turmoil since a hundred years ago, and the plans of heaven are spread throughout every corner of this city. The Masked Man uses his mask as a protection, and stirs up troubles according to eight major factions: greed, rage, and cowardice. Antiquities buried for thousands of years are also eyeing the enemy, and the fight between fate and fate has never stopped. I originally thought that the closed loop of heaven was unbreakable, but when I unexpectedly came to the Republic of China in the 16th year, I fell into confusion. I can clearly see everyone's destiny, but I can't clearly see the starting point of the catastrophe a hundred years ago, nor can I clearly see my true position in the chess game of Tiandao. The Feng family's blood curse, the dead family's key, and the seal in Yu Ruyi are all wrapping around my fingertips along the river of time. I originally thought that I was the chess player, the one in charge of balancing heaven and earth, but in this game set by heaven, I suddenly realized... I may be a variable that Heaven has failed to calculate, but I am also His sharpest knife; I can clearly see everyone's destiny, but I can't see my own ending. The war between Shuntian and Ni Ming has been rekindled, and the dust-laden fates have been unveiled one by one. I will take charge of Tianheng as a lonely soul. But do I want to follow the script written by heaven, or do I want to fight for lifeless freedom in the world?
