I’ve Transmigrated, but I Still Want to Go Back

Can someone please explain to me what the protagonist's cheat code is? I've only read a few chapters, so I might not have paid close attention, but I'm completely confused. How does the protagonist have modern weapons? And what's with my personal space?

Keep it up! It looks great, and it's right up my alley. 😘😘

It's pretty good, but there are some issues that need to be addressed later.

I finished reading it in one night. The author wrote it quite well; in this era of wish-fulfillment novels, it's a real gem in the online literature world.
