Mistakenly practicing magic skills, causing chaos in the martial arts world

"Have you heard? A new demon has appeared in the world?"
"But that old demon Shi who claims to have amazing wisdom?"
"Yes, it's that devil! That devil is very powerful in martial arts, and he often uses a wrong secret book to make the whole sect crazy and insane! He enjoys it!"
"That's what I heard! The devil is really crazy!"
Half of a magical secret book opens up Shi Feizhe's journey to martial arts!
When he was invincible and everyone wanted to kill him, he faced the rumors and angrily said:
"What? Did I practice wrong?"
"Impossible! Absolutely not!"
"We have the same technique, but I'm obviously stronger!"
"You can't practice because you don't have enough talent. It's your problem! You are the one at fault!"
"No one knows martial arts better than me!"
