Put it this way: 280,000 "Origin" was enough for him to do absolutely nothing and stay in the Mysterious Shop for... six years.
Holy crap, how could it be this brutal!?
Well, it could actually be calculated. Don't let such a huge number fool you—based on the monthly increase in "performance," the first half-year was 6,000, the second was 9,000, the third was 12,000... the tenth half-year would be 33,000...
By the nineteenth half-year, it would reach the cap of 10,000 "performance." By the Mysterious Shop's reckoning of time, that would be nine years later. Was that a long time?
For a Mysterious Shop that had existed for who knew how long, that amount of time was nothing! And by then, the total "performance" Jiu Ming needed to reach would be 627,000. Ahahaha... wasn't that far harder than an ordinary person saving up that much money over ten years?
Fine. With that method, Jiu Ming successfully calmed down. He had never seen a one-use item worth so much. Then again, its heaven-defying nature had reached the point of reversing time itself!?
Just think of the loop in Suzumiya Haruhi's world—a whole world's time "rolled back." Was that something a human being could even do!?
No need to doubt it. Judging by the scarlet warning words in the notes alone, he would never use this Sealed Card. Since all backlash had to be borne by himself, then even if time was reversed after using it, Jiu Ming himself definitely would not survive. He was not Suzumiya Haruhi...
An unprecedented collectible. After swiftly giving it that designation, Jiu Ming directly put it away. He probably wouldn't be able to obtain a more precious "collectible" in his lifetime.
A strange curiosity made him badly want to recklessly use it once, just to see
