Is This the Method I Learned?

In January XXXX, an unemployed man with a bachelor's degree in law was reincarnated into a different world while looking for a job, and found out: What does it mean that a bachelor's degree in law is awarded a master's degree? What do you mean the red tome you have read is actually a basic skills book? What does legal examination certificate actually mean as a job transfer certificate? Which method is this for you? ! Oh? The good news is that the knowledge of the original world is available. The bad news is... You are an undergraduate who has been throwing away books for a while after taking the law exam! Let's see how Yu uses the remaining knowledge in his mind to become a mage in another world (Even if you arrive in another world, you still have to study hard, Saonian!)
