Magician: My Magic Has a Critical Hit

This is a magical world. There are monsters, humans, birds and beasts in this world, as well as all kinds of magic. Demons live in groups, small ones gather into tribes, and large ones form empires of demons. Humans can only live in the demon empire and rely on the profession of magicians to resist the demons. Qi Yang dreamed of becoming a magician since he was a child. He awakened a unique talent - all magic is born with critical strikes! While other magicians were still scraping the demon, he hit the demon with one move and made the demon scream in pain! His flat magic is considered a ultimate move by others!
