A Hundred Years Hiding in the Demon Sect, and Every Spell I Know Is Forbidden!

[Steady growth] + [Decisive and ruthless] + [System cultivation] + [A nobody rises to greatness] Xu Zechuan transmigrates and becomes a low-ranking nobody in a demonic sect. Luckily, his golden finger awakens: his cultivation techniques can be upgraded without limit! In his hands, even simple spells can become terrifying divine arts of immense power! [Fireball] upgrades to [World-Destroying Fire Lotus], increasing its power a millionfold! [Swift Movement] upgrades to [Golden Light Across the Earth], letting him travel ten thousand miles in an instant! [Healing Spell] upgrades to [Immortal Grace Shining on All], capable of reversing death and bringing the dead back to life with a single drop of blood! So Xu Zechuan keeps a low profile in the demonic sect, constantly growing stronger, and sets out on the road to immortality. Years later, when righteous cultivators besiege the sect, Xu Zechuan swats them with a single palm. The wind howls, and countless human emperors fall. Everyone stares in shock. “You call that a Gentle Breeze Spell?” Xu Zechuan smiles calmly. “That’s right, it’s the Gentle Breeze Spell. Though these days, I prefer to call it the Forbidden World-Destroying Gale!”
