This Is a Magical Sky Screen

I know the cover isn't very good, and it doesn't measure up to other people's. I made it myself.

Don't sweat the details.

Sky screen, a male lead who's just a tool, a System, and light interaction across different worlds.

History is full of regrets.

What if Qin Shi Huang had known his dynasty would fall after just two generations?

What if Emperor Wu of Han had known about the Witchcraft Disaster?

What if Emperor Taizong of Tang had known about the An Lushan Rebellion?

Here, I'll do my best to make up for those regrets.

Let's watch the future together.

[The focus of this book:

It may not be the best, but it will certainly cover a lot.

From ancient times to the modern era,

from rebellions to resisting Japanese pirates,

from World War I to World War II,

it's all here.

And this book leaves no regrets: these figures will get the happiest endings possible.]
