Nowadays, Luo Zhen possesses not only a huge knowledge of spells, but also a vast amount of magic knowledge. His attainments in various spells are unparalleled in the world, just in terms of the amount of knowledge and the number and types of spells. , let alone modern magicians, even magicians from the age of gods are not as good as Luo Zhen.
