My Territory Leads Straight to Terraria

One day, Charlie wakes up to find he has transmigrated into the lord of a remote barony in the desert.

Greedy dragons, bloodthirsty demons, beautiful elves, restless undead, and a human empire on the brink of war.

It's hell difficulty from the start.

No problem.

He can just open a portal in his territory leading to the world of Terraria.

Soldiers!

Go explore the new world!

After Charlie returns to his territory with his loyal army, having torn the Empress of Light to shreds and charged through the Moon Lord, along with treasure and supplies...

What?

Dragons are attacking?

Demons are invading?

A tide of undead is surging in?

Do they think my [Zenith] is too dull, or that my [Solar Flare Knights] aren't dazzling enough?
