Demon Nobles

Lin En traveled through the world of Demon High School and became the fourth young master of the Phoenix family, one of the seventy-two pillars of the pure-blooded demons. He awakened the supreme optimization system and embarked on the path of cheating.

The bloodline was optimized, and the Undying Bird bloodline became the Phoenix bloodline!

[Weapon optimization: Iron Sword to Holy Sword!]

You know the effect of optimization, hehehe.
