My Spells Are Endless

When he wakes up, Zhou Bingwen, a top student in mathematics, travels to a world based on a mage. Although the mage is powerful, he has a fixed number of spell slots and can only cast a fixed number of spells every day. When he discovered that the so-called essence of magic was mathematics, there were no restrictions, and he could improve and strengthen the magic himself. When someone else casts [Mage's Hand], he backhands a [God's Hand]. Others used [Detection Magic], but Zhou Bingwen used [God's Gaze]. When others no longer had spell slots and could only fight melee with swords, Zhou Bingwen directly used spell firepower to cleanse the ground. When the alien army came to the city, Zhou Bingwen stood alone on the city wall and told the world what a true mage is!
