In October 2016, a war broke out among humans, which caused earth-shaking changes in the earth. Green plants became rare and precious. In the 22nd century, humans explore aliens, and aliens bring vitality to humans. In the twenty-sixth century, the earth is teeming with life again, even more so than six hundred years ago.

On the continent called Europe six hundred years ago, deep in a dense forest, there was a castle that had been abandoned for many years. I don't know when someone spread the news of its existence. It was said that there were rare treasures there, elixirs that could bring people back to life, and secrets of immortality... Some even said that finding that castle could save mankind from the gradual extinction of mankind. So countless people walked deep into the forest, but no one could save their fate. ...
