Universal Mage: I Rely on Cheap Spells to Transform into Natural Disasters

In this era where mages are the most respected and magic is highly commercialized, a basic attack spell can easily cost 70,000 to 80,000 yuan, while a bottle of magic potion can cost as much as 1,000 yuan. Zhang Ning, who had traveled through time, touched the five thousand yuan in his pocket and fell into deep thought. Fortunately, he has awakened [All Magic Enlightenment]: As long as he masters a spell, no matter what the quality is, he can permanently increase his mental power by 1 point. And when the proficiency is full, it can be fired continuously without cooling down! Can't afford tens of thousands of dollars worth of fireball skills? Zhang Ning turned around and set his sights on the "Water Film Technique for Cleaning" worth 3,000 yuan a book, the "Conductive Mark" for industrial use, and the "Low-Level Thunder Technique" for dog repelling... When the rich second-generation geniuses of the same class exhausted their mental energy and finally suppressed a gorgeous high-level magic. Zhang Ning just raised his hand expressionlessly, and instantly threw out hundreds of cheap thunderballs with tracking capabilities. Zhang Ning looked at his opponent who was instantly overwhelmed by a massive amount of spells, and calmly put down his hand: "Sorry, my spells have not cooled down." ——This is the story of a poor mage who relied on waste spells at the beginning to blast through the entire era.
