A Mystery: Innate Fate Sacred Body

Good news: I transmigrated.

Bad news: I transmigrated into a book I have never read.

What should I do?

Right, before transmigrating I watched a fan-made video, so I just need to follow what it said.

1. The Assassin potion is better for staying alive.

...

4. If you want to develop a hobby, buying a telescope to observe the starry sky is a pretty good choice.

5. The official personnel in this world are extremely dangerous. They will treat you, the transmigrator, as a heretic and wipe you out. If you run into them, you must pick up the handgun next to you and defend yourself.

...

7. If you think advancement is hopeless, you can try reciting Amon's honorific name; this will let you advance straight to angel.

8. If you encounter a problem you cannot solve, you can shout Leodero toward the sky, and all problems will vanish.

...

Very good: first choose Assassin, spend your free time using a telescope to look at the starry sky, shoot the police if you meet them, call on Leodero whenever you are in doubt, and if advancement does not work, shout Amon. The formula instantly kills everything.

Looking at the task sheet in his hands, Luo En is full of confidence.

...

A long time later, Luo En, now an angel, looks at the task sheet, on which not a single thing has been completed, and sighs.

How did I end up accomplishing nothing at all?

PS: The main plot is from Lord of the Mysteries.
