A Hundred Years in the Demon Sect, My Spells Are All Forbidden!

Xu Zechuan transmigrates into a demon sect as a low-level talent. Fortunately, his golden finger awakens, allowing him to infinitely upgrade his techniques. Simple spells become terrifying divine skills with immense power. [Fireball] upgrades to [World-Destroying Fire Lotus], power increased a million times! [Swift Step] upgrades to [Golden Light of the Earth], traveling ten thousand miles in an instant! [Healing Art] upgrades to [Immortal Grace Shining Everywhere], reversing life and death, regenerating from a drop of blood! Thus, Xu Zechuan hides in the demon sect, continuously improving his strength, paving a path to immortality. Years later, righteous experts besiege the mountain gate. Xu Zechuan slaps out, wind howling, countless human emperors fall. Everyone is shocked: "You call this a gentle breeze technique?" Xu Zechuan smiles calmly, "That's right, it's the gentle breeze technique, but now I prefer to call it forbidden—World-Destroying Gale!"
