Shen Yuan has been able to see things that others cannot see since he was a child - the line of cause and effect, the knot of fate, and everyone's countdown to death.
His grandmother told him before she died: "This is our family's fate and our family's disaster."
The truth she didn't tell was that the bronze fragment in Shen Yuan's hand was sent back by his future self from three thousand years old. In the future, he became the strongest man in the nine realms, but was betrayed by the people he trusted most - because he wanted to sacrifice the entire world.
That disaster was called calamity, and it was the "residue of fate" left behind by all the people who had changed their destiny in countless epochs. The fate of the previous era, "Xu", turned himself into a living calamity, sleeping in the world of chaos, waiting for Shen Yuan to offer his eyes for him.
Su Wanqing is Shen Yuan's childhood sweetheart and the successor of the Guardian. She has only one mission: to kill Destiny with her own hands when he loses control.
Grandma arranged Su Wanqing by his side, which was both protection and final insurance.
Now, the calamity is coming and the ruins will wake up. Shen Yuan finally understood: everything he saw was planned by his future self.
But this time, he didn't plan to follow the script.
