My name is Su Chen, a time traveler, and the oldest alchemy outer disciple in the sect. I am eighty years old, at the third level of Qi refining, and only have the last three days of my life left.
Just when I was about to lie down and wait for death, I accidentally activated a mysterious ancient coin that could "retrace" the state of all things.
Unfortunately, it cannot trace back to myself.
But... It can trace back everything!
