Misguided Evil Cultivation: Heaven and Earth Manifestation

This is a bizarre and mysterious world, filled with all sorts of evil and strange cultivation methods. Once a person practices them, in mild cases their appearance and temperament change and they fall into demonic madness; in severe cases they become a Great Medicine, to be harvested and devoured by evil demons......

Duan Yun transmigrated here and accidentally obtained a Great Medicine cultivation method, Jade Sword True Explanation.

Unexpectedly, he is a one-in-a-million cultivation genius. Unaware of the truth, he transformed this technique, turning it into something entirely new—the jade sword points the way, piercing through everything.

Later, as he mastered more and more techniques, with the ideal that "when one is accomplished, one should benefit the world," Duan Yun never kept his knowledge to himself and spread martial arts across the world.

Who would have thought......

"Demon Duan has ruined me! He told me this technique nourishes yin and strengthens yang, but now I can only squat to pee, sob......"

"That devil taught me this Sevenfold Returning Origin Qi. Now I'm either getting killed or stepping in shit. The fortune-teller said I've lost seventy percent of my luck."

"Don't listen to a single word Demon Duan says! The fairies of the Myriad Wonders Palace were about to ascend to heaven with the entire palace, but instead they fell into demonic ways overnight and became wicked women—all of this is Old Devil Duan's doing!"

......

Duan Yun was very puzzled. He had only practiced martial arts, passed on techniques, and occasionally used his Heaven and Earth Manifestation—how did he become a devil whose crimes are too numerous to record?

This is slander!

It's the same cultivation method—why don't I have any problems?

You're the ones who are wrong, it can't be me!
