This Is Not Lord of the Rings

Just a few casual complaints about life being unsatisfactory, you traveled through time, became a person named Fullerdo, and got a powerful golden finger: the Supreme System. You feel that you are going to be successful and reach the pinnacle of life. But the Great Elemental Master Gan Tofu tells you: This Supreme Gold Finger is the King of Gold Finger created by Black Queen Soni, with the intention of using it to control and conquer mankind. Now, Sony already knows that the Supreme Finger has fallen into your hands. He also tells you that the power of the Supreme Finger will make the holder corrupt and become a slave of Sony. To destroy the Supreme Finger, you must put it into the formatting factory where it was originally manufactured; that factory is located in the Magic City, Sony's home base. Although you don't quite believe it, you still embark on the journey to destroy the Supreme Finger. Along the way, you continue to encounter various obstacles: the pursuit and interception of Sonny's minions - the Knights of the Death King, the betrayal of humans with ulterior motives, the attacks of mutant monsters, etc. However, what can really prevent you from destroying the Supreme Point is the Supreme System itself: its powerful temptation makes you sink deeper and deeper... You feel like you are in the world of "Lord of the Rings", but obviously: this is not "Lord of the Rings"!
