The Last Watch: Age of Rust

The sky at the mouth of the Yahe River was torn apart, and the "living darkness" that poured out swallowed everything. I, forensic doctor Li Tinglan, am the only survivor of that "Guardian" purification. For the rest of my life, I was warned: The ancestral jade fish in my neck was the final key to activating a certain "corroded system"; my family's bloodline was the only evidence to repay a debt that spanned a century. The countdown to system collapse has begun. Under the deep sea, the forgotten "countercurrent spring" is awakening. A contamination known as "Whispers of Decay" spreads from within. The mysterious "Ouroboros" foundation, the "disciples" cultists who worship nothingness, the abnormal bureau that shoulders heavy responsibilities... All forces regard me and the key in my arms as targets that must be captured or destroyed. Deep in the rusty ruins, the final truth is waiting to be revealed. And I, the chosen "Watcher", will hold the short bronze blade that resonates with pollution and make a choice—— Is it to repair this collapsed world, or to be the... Last link that buries it?
