This Necromancer Is Strong but Too Timid

[No system + easy + genius + complaints + different worlds] Zhou Che, a college student, jumped into the pool to save someone. Fortunately, he was rescued. Saving one life is better than building a seven-level pagoda. The sad thing is that he didn't come up himself. After all, crispy college students are really not that difficult to kill. As soon as his legs cramped, he met the King of Hell in a trance... Well, he actually didn't see the King of Hell, but after opening his eyes, he found that he had been reborn in another world. This is a world completely different from the previous life. What this world has developed is not technological civilization, but has been replaced by more brilliant and harmonious powers such as magic and fighting spirit. What is even more fortunate is that the German family into which he was born is one of the most prosperous nobles in this continent called Norman! With no shortage of connections and resources, Zhou Che, who changed his name to Winston, had a great dream. He wanted to become one of the top magicians on the continent. It was just a little joke played by fate on him. He did have unparalleled talent in magic practice, but it was a pity that he focused on necromancy. He is a coward who wants to practice necromancy and deal with the undead all day long? Who would love to be this necromancer... No, this career seems to be pretty good?
