Authority Fragments of the "Compassionate Heaven and Earth Castle"

[Across boundless heaven and earth and endless time, no living being at one place and one moment can know how events will unfold at another place and another moment. But you, perhaps, can.]

[Fate gives you a hint.]

[Fate Hint One: Based on a previous "Fate Hint," you learned that the true goal of "Great Copper of the World" is to go beyond the "Blue Star Federation" and truly unify all of spacetime. However, completing a task of this magnitude requires an immense amount of time and gradual effort. But now, infected by the "Virus Source Species," you have gained the possibility of accelerating the task after obtaining the skill "Gold-Silver Conversion." Harvest vast numbers of the Longevity-Cursed Species, seize the "Gold Coins" and "Silver Coins" in their possession, and convert them using the "Gold Crystal" and "Silver Crystal" you hold, while secretly retaining one "Copper Coin (Second Chapter)." Remember, Human Kind, you may secretly retain only one, and seizing that one requires the right timing.]

[Fate Hint Two: "Great Copper of the World" will eventually begin. Wait for it to begin naturally, approximately 500 to 900 years from now.]
