The mage who walks in the heavens
(Newbie's work, description is weak, if you don't like it, I'm sorry)

"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?"

Two biggest mistakes of this novel, one entering MCU in 2017 after civil war and before infinity war just ruins things most for me as most of MCU plot has ended and what's the point of transmigration if you transmigrate after almost all the initial plot of the story is done and second you chose Micheal Jones (Zendaya) as love interest. I'm not picky with women in harem novels but with non harem ones I only read those that have my waifus as love interests
