Lu Mingfei doesn't want to be a superhero

Lu Mingfei's Diary:
On February 10, 2009, I was transported to a terrorist base in the Middle East. There was a man there who called himself Tony Stark, and he said we would soon be executed by the terrorists! I want to go home!
February 11, 2009 Great! I'm home. It's so wonderful to have a peaceful world without any weird things!
On April 25, 2009, I traveled back to that world again. It seems that I have to keep traveling back and forth between the two worlds. Fortunately, my world is peaceful and normal.
On May 5, 2009, I discovered dragons in my Minecraft world. [Swear words crossed out]
……
I got a girlfriend on May 20, 2012. Erii is so cute.
……
Years later, Lu Mingfei, now the Sorcerer Supreme, Prince Nidhogg of Asgard, Principal of Kassel College, the new Dragon Emperor, and savior of the universe, cried out with a long face, "I really don't want to be a superhero! Did I get the wrong script?!"
This book is also known as — Lu Mingfei, who has repeatedly returned from Marvel.
