The protagonist can instantly obtain the corresponding level of martial arts, medical skills, or fortune by sacrificing his "longevity," "cultivation," "luck," or even "future opportunities." Other protagonists become stronger, while the protagonist becomes stronger through "self-mutilation". In order to protect his wife and daughter, he burns himself. This "tragic hero" color is more impactful than simple pretense.
The protagonist, Jiang Chen, who is married into the Su family, is actually the reincarnation of the Nine Heavens Emperor, and he abandoned his cultivation in order to suppress the evil spirits within his body. After the system awakens, he must walk a tightrope between "suppressing the evil spirit" and "sacrifice to save people."
