The Reversal of Heaven Begins with The Smiling, Proud Wanderer

Lin Mu transmigrated into The Smiling, Proud Wanderer and obtained the Reversal System, which can turn the side effects of any cultivation technique, elixir, or spell into positive ones.
[The Evil-Repelling Sword Technique: Derived from the Sunflower Manual, a top-tier sword technique in the martial arts world, with rapid cultivation. Side effects: Practitioners will develop evil thoughts and experience internal fire during practice; to master this divine skill, one must first castrate oneself.]
[Negative Reversal: After cultivation, one generates pure Yang energy and righteous Qi, achieving success without castration.]
[Star Absorbing Technique: Modified from a fragment of the Northern Darkness Divine Art, it allows the user to absorb internal energy to strengthen themselves. Side effects: Difficulty in refining foreign internal energy; excessive absorption can easily lead to backlash.]
[Negative Reversal: Can purify all true energy, instantly refining and absorbing its power.]
[Drugs: Inducing unconsciousness and drowsiness.]
[A negative turnaround: It makes you feel refreshed.]
The greater the side effects, the greater the benefits.
