Sparks in the Long Night: I Slay Demon Gods in the Mortal World

[Warning! I've gone completely mad. There's some buildup at the start, then it's nothing but heartbreak. I'll make you suffer, hahaha!] [Probably no female lead + urban setting + no System + no holier-than-thou protagonist + invincible + sunny, healthy, and uplifting] Sometimes, is being more clearheaded really a good thing? By chance, Shen Ziyan awakened a special ability: his eyes could see through illusions. He saw the deadly crisis hidden beneath the peace, and endless dangers soon came one after another. Gods and Buddhas from all the heavens, ghosts, monsters, demons... From that moment on, as a mere “human,” he embarked on a path that set him against the entire world. In the end, we will pay a heavy price for being “clearheaded.” Shen Ziyan believes that confusion comes from having too much idle time. Once you get moving, your goals become crystal clear! Facing the gods and demons of the heavens, Shen Ziyan stands alone to defend Tianhua, sword in hand and horse beneath him, blood staining the sky. “Sixth Seat of the Spark Society, Shen Ziyan of the human race is here! Who among the heavens dares fight me?” (The protagonist is ruthless and decisive, killing from beginning to end.)
