MTL - Godly Student - Chapter 9 Home niece?

The world is about to be destroyed to make way for an interstellar transmission array formation. A young man journeys through the stars to save his home. A bloody fantasy adventure.

When Yohan woke up in the morning, he had a beauty in his lap and in his bedroom. It was like a dream come true for him until reality struck him.

“I have made too many efforts to safeguard world peace. I am convinced that under her leadership, there will be no chance of the demons returning to the country.”

In the winter of 1802, the demons successfully restored their country.
