I Am Gu Xuan, the Strongest Protagonist

[Trick people flow] [Invincible flow] [Extremely cool writing without breaking the brain]! Gu Xuan has traveled through time, and he is the Holy Son of Taixuan Holy Land. Congratulations--- Oh! The mentally retarded system actually made him the ultimate devil! The more evil you do, the higher the reward! "What? You said I killed too much? Slander! Pure slander! If you have the ability, call those people over and let us confront them face to face? Can't call them? If they can't be called, then what are you calling for? Come here, pull them down and behead them!" "What? You say I'm a scumbag? Well... You're really good at reading people!" "What? You said you are the Son of Destiny and want to challenge me? Hey, get in line, man. I have eight Sons of Destiny instead of seven. If you want to duel with me, ask my secretary for a schedule!" The Holy Son is invincible and has been popular throughout his life. If you say he is not the protagonist, who would believe it?
