I'm on chapter 3553. the author keeps stating the MC isn't ignorant but he's very arrogant and ignorant. someone who just started learning martial arts and has reached far but always confident he can kill everyone, always going out of his way to show his arrogance. the story started off good while he was on earth but after that it became every other martial art story. he suffers 1 setback out of every 500 situations. I can't see myself fully reading all 12,000 chapters. I'll keep reading for now to see the character development or if there is any at all besides an arrogant, ignorant person who's always invincible to everyone.
