Can you recommend some novels with similar settings to Black Mirror?

It was basically a story where the protagonist's cell phone connected to another world, and then the earthlings went to another world to play a game to do a mission to save the other world.
The setting of the Black Mirror Era was quite good, but it was too hard to write.

Answer 1

I recommend a novel similar to the Black Mirror Era, called "Hyper-Virtual World". This book is about a character who obtained a powerful game item,"Super Shelves", while playing a game. However, this item displayed unimaginable power. This novel belongs to the category of virtual online games. There are many settings similar to the Black Mirror Era in the plot. I believe you will like it. I hope you like my recommendation. Muah ~
