Before he passed away due to old age, Zhang Zhixuan is a well known Celestial Refiner that stands in the peak as the third Pinnacle Legend of all the Celestial Refiners. Only two people stronger than him, and billion of Celestial Refiners below him.
Still, he failed to overcome the border between mortal and immortal, which is known as the Trial of Age and Time.
As a Pinnacle Legend that overcomes more than two seasons of the Refiner Realm's War, it stunned him to hear about the incoming Refiner Realm's War, which was already started when he's reborn into this world once again.
But the trouble still followed him wherever he goes.
Failure to obtain any reading material that was useful to explain his whereabouts, the reborn Zhang Zhixuan can only put more effort into exposing the secret covering this unknown realm and protect them from being consumed by either the Erosion Refiner or Putrid Refiner.
His first task?
To make sure he knows why their civilization remained rural, undeveloped, and of course, inefficient.
His first challenge?
To not get angered to his death of course!
