This is a bizarre and mysterious world filled with various sinister cultivation methods. Once a person begins to cultivate, they will either undergo mild changes in appearance and temperament, descend into madness, or become a great elixir for evil beings to consume...Duan Yun, having transmigrated into this world, unexpectedly comes across a supreme elixir cultivation manual, the 'True Explanation of the Jade Sword.'To his surprise, he is a one-in-a-million cultivation genius who, unwittingly, transforms the manual into something extraordinary. Guided by the Jade Sword, he is able to pierce through everything.Later, as his mastery over various methods grows, Duan Yun, carrying the philosophy of 'the enlightened benefit the world,' never keeps secrets and spreads martial arts across the land.Who would have thought...“Duan the Demon misled me! He said this technique enhances yin and yang, but now I can only squat to pee, boo hoo...”“It was the Demon who taught me this 'Seven Parts Returning Qi'.

All he did was practice martial arts, spread techniques, and occasionally emulate the laws of nature, so how did he become notorious as a demon?This is slander!The same techniques cause no issues for me, so the problem lies with you all, not me!
