Simultaneous Travel: But It's Always Hellish Difficulty

A very familiar time travel.

But the problem is, no matter which world you travel to, it's always hellish difficulty?

A harmonious and friendly game world, but the absolute zero zone has become a skeleton.

The free-spirited America, but due to a combination of biochemical changes, has become a zombie.

It's an anime world full of girls, but the Greatsword Demon is still a male Greatsword user.

I finally arrived in a Western fantasy world, but you're telling me it's The Band of the Hawk? Oh my god, it's Berserk!

Finally, after much difficulty, we arrived in Hong Kong Island.

But what exactly is Lanmeng Company?

...

In short, it's a group of unlucky time travelers.

Survive in worlds of various hellish difficulty levels.

And strive to tell stories that penetrate the world.
