Just as he was about to die, the most powerful kryptonian life system awakened! Consuming lifespan can quickly deduce martial arts! Song Ci: Max out my money! Not enough life? Hunt demons to absorb life! Many years later, Song Ci stood at the pinnacle of martial arts, looked back, and couldn't help but sigh: I just wanted to slay demons and monsters, how come I became invincible?
