I, Gu Xuan, Am the Strongest Protagonist

[Schemer Protagonist] [Invincible Protagonist] [Pure, Brain-Off Fun]!

Gu Xuan transmigrated and became the Holy Son of the Supreme Mystery Sacred Land. What a joyous occasion---

Wait, no!

The idiot System actually wants him to become a peerless demon lord! The more wicked his deeds, the greater his rewards!

“What? You say I've killed too many people? Slander! Pure slander! If you've got the guts, bring them here and let us face off! Can't bring them? Then why are you making such a fuss? Guards, drag him away and execute him!”

“What? You say I'm a womanizer? Hmm... You certainly know how to read people!”

“What? You say you're the Child of Destiny and want to challenge me? Heh, get in line, buddy. I've already got at least seven or eight Children of Destiny running around. If you want to fight me, ask my secretary for an appointment!”

The Holy Son is invincible, sweeping through his age. If he isn't the main character, who is?
