I, Starting in the Wasteland, Have a Small Fantasy World

As a hostage to the subjugation of the country, on the day I was exiled, the Heavenly Master of the empire declared that I had committed a sin of fate and would die in the Cursed Wasteland with no bones left. He didn't realize that there was a seed hidden in my soul. They regard it as the curse of the Jedi, which happens to be its best nourishment. When I planted the first spiritual rice in the wilderness, rescued the first batch of refugees, and built the first wooden house, I thought this was just the beginning of a revenge story. Until that day, in order to expand the shelter, I punched open a rock. The rocks collapsed, revealing not earth and rocks, but a wisp of ancient spiritual energy that was so pure that it made the entire wasteland tremble. At that moment, the imperial city in the north was shaken by dragon energy. The Heavenly Master spurted blood from his mouth and exclaimed, "A change has occurred." On the Black Wind Mountain to the west, the cold and charming female village leader suddenly stood up and looked in my direction, her eyes full of horror. I finally understood when I looked at the abyss where spiritual energy gathered. They didn't exile me here to let me die. But the huge secret of this wasteland has been waiting for a... Key like me.
