Three Thunders

After an unknown amount of time, the king finally grew tired of it. Although he was sitting on everything in the world, he felt more and more boring. Even a king needed entertainment. This national library and academy is known as the world's encyclopedia, and it is said that its collection is so rich that it can even rival the king's collection. Therefore, he issued an ultimatum to everyone in the academy, requiring them to find all the rare treasures in the world to please him within a specified time limit, otherwise they would be sentenced to death.
