Fifteen years later.

December 25th.

Along the banks of Lake Ying, a thin layer of ice had formed on the lake's surface, and the surrounding cherry trees were already bare.

But next to it, the modern science museum was bustling with activity, welcoming two middle school student groups for a visit that afternoon.

From the outside, the building's layout still resembled that of a school. If one were to look down from the surrounding heights and see a campus full of students, they would never imagine it was a museum.

Inside the "classroom building," however, everything had been turned upside down.

Undoubtedly, the most attractive exhibit was the "double-slit interference demonstration."
