The mage who walks in the heavens
(Newbie's work, description is weak, if you don't like it, I'm sorry)
Traversing other worlds, cultivating magic, and conquering other planes, he discovered that every plane was a familiar world. Marvel,(CD, anime, Hong Kong, 2D, none of these currently available), and so on…
"Hmm? Doctor Strange wants to borrow my power?" "Agreed."
"What, Harry Potter got beaten up by Voldemort, and you want me to come over and support him?"
"Gandaph, don't be idle, go help!"
"What is it? The Holy Master ran out again?"
"Ghidora, go and exchange a few moves with the Holy Master. If you lose, don't come back."
Merlin looked at the messages sent by the worlds under him and could not help but sigh.
"It's really tiring to be the big brother of the myriad worlds. I want to retire!"
This was the story of a mage walking in the heavens.
Quite an interesting way to start the book by having the MC go into the world of Harry Potter and become Gildroy Lockhart after that talk with the mysterious person not to mention the effort and understanding to learn the different spells and be proficient in them but also way handled lesson plans by going to Ministry and knowing about the level of the curriculum and what is expected of the student's year and how he taught the different classes including the incident with the slugs and using the cornish pixies to teach in a way overall I have enjoyed reading this book not to mention it had caught my attention and got me intrigued and interested in it different from other books by way it starts and how it progresses do look forward to reading more of this book when ur able to get the chance do look forward to it
