Relics Return: When the Strange Descends

In 2050, the polar ice caps have completely melted, sea levels have risen globally, and celestial anomalies occur—auroras spread to the equator, and the moon's halo turns red. Every Chinese cultural relic lost overseas simultaneously emits a "sigh." Thereafter, all countries are forced into a brutal "National Fortune Competition." [Instance Rules] Each lost Chinese relic generates an independent "strange instance" in the void. Inside the instance is a nightmare manifestation of all the resentment, tears, and humiliation from the relic's century of exile. Those who clear the instance add 5% to their nation's fortune; those who fail burden their homeland with a 5% curse. When the instance ends, the exiled relic is forcibly returned. If anyone dares to obstruct, the nation's fortune is doubly deducted. [A century ago, the relics were taken; a century later, they become instances, demanding a price from the world. Only by letting them return can we save our nation's fortune.]
