I Burn Lifespan to Grow Stronger in the High Martial World, and My Flames Can Evolve Without Limit

[High Martial Arts + Supernatural Abilities + Trading Lifespan for Power + Flame Evolution + Ruthless Combat + Power Fantasy] Li Heng transmigrates to a high martial arts world overrun by mutated beasts. Awakening a supernatural talent and becoming a martial artist is the only way out for ordinary people. Li Heng stares at the E-rank talent at his fingertips, [Flame Spark], lost in thought… Just then, Han Qianqian, the class beauty he's secretly in love with, appears before him and says arrogantly: "Li Heng, don't take part in this afternoon's class selection for the ruins training camp." "Haotian is aiming for a top-tier martial arts university. He shouldn't waste his strength and time on someone like you." Li Heng freezes for a moment, then lets loose a choice string of profanity. "Screw giving up, you idiot! Get lost!" [Ding! Host detected insulting a goddess. The Great Villain of the High Martial Arts System has been activated. Lifespan +30 days!] [Spend twenty years of lifespan to cultivate an E-rank technique to the Return to Simplicity Realm!] [Spend thirty-one years of lifespan to evolve the talent Flame Spark (E-rank) into Scarlet Serpent Flowing Flame (C-rank)!] [Spend…to evolve into the A-rank talent: Azure Flame of Guixu!] At the selection contest, the martial arts teacher watches Li Heng punch his opponent flying and stares in shock! "What!?" "Li Heng is only a high school senior, and he's already cultivated a fist technique to the Return to Simplicity Realm?" At the genius training camp, the instructor watches Li Heng's movement technique, fist technique, and spear technique, all at the Return to Simplicity Realm, and feels his blood surge! "Could he be a once-in-ten-thousand martial arts genius?" At the four major universities, the martial arts grandmasters look at Li Heng's profile, the corners of their mouths twitching violently. "You're saying this student evolved from an E-rank talent to an S-rank one?" "Nonsense! He's clearly my very own disciple, even though we've never met!"
