Celestial Master: My Golden Light Spell Leveled Up in One Second and Became a Nuclear Bomb

Mu Feng transmigrated here and woke up to find himself lying in a hospital bed, being humiliated by his girlfriend. He thought he had stumbled into a melodramatic romance. Unexpectedly, the very next moment, an old man who called himself a Celestial Master passed on all his lifelong power to him! Mu Feng inherited the title of 65th-generation Celestial Master! Then he was told that strange phenomena would return in a day. By then, heaven and earth would undergo a cataclysmic transformation, and the entire world would be shrouded in a blood-red shadow! Ding ding ding! Warning, warning! There are no skills available for upgrade. The System is furious and about to self-destruct, sending its host to meet the King of Hell! Looking at the Golden Light Incantation and Five Thunder Rites he'd casually activated, Mu Feng fell into deep thought. Is this really the Golden Light Incantation? Why does everything around me disappear when I say the words? And the Five Thunder Rites... Whose lightning comes down like a waterfall? Someone who didn't know better would think we were setting off fireworks!
