The Death Mage's Diary

Thor transmigrated to a world full of bizarre and dangerous magic. To survive, he resolved to overcome all obstacles and become a mage. But in this terrifying world, both apprentices and official mages face constant mortal peril. Thor is an even bigger target for persecution. Fortunately, he obtained a diary that can predict the future. However, all the future predictions in the diary are:

[You died, your body drained of all blood]

[You turned into flower fertilizer and were quite satisfied with your new form.]

[You died laughing]

[Three years later, you became someone else's potion ingredient.]

Thor: (╯‵□′)╯︵┻━┻ I don't want this cheat anymore!

Wait, Thor's eyes lit up: Did I just eliminate another wrong option?

Not long after...

Diary: (╯#-皿-)╯~~╧═╧ This cheat is really not what a book should be doing!
