Immortal Industry.
As the name implies, it is the Merits mastered by the Immortal God.
No matter what technology, no matter what principle, as long as one masters it and reaches that 'unified' 'result', then mastering it itself is enough to be called a great leap, even akin to Ascension.
Attaining Immortal Industry, then Ascending to Immortality.
Every Immortal Industry represents a celestial path that can achieve an undying Immortal God that theoretically stands at the pinnacle of a world.
It can even be said that the term 'Immortal God' exists because of 'Immortal Industry'.
Because, in many planets and planes, in the countless worlds, within numerous native extraordinary civilizations, the first being to reach this realm will naturally become the supreme Heavenly God, Immortal, or Demon King of that world.
