Speaking up to this point, Eldest Sister stopped in her tracks, and waited for Suo Jia to catch up before once again striding forwards. As she walked, she said, “About 20 years ago, the western aristocrats presented a few bottles of fine liquor that had very unique flavors to Duke Wen Sha as gifts. However, these bottles could not be stored at room temperature, because if the temperature was too high, the liquor would turn sour. The bottles could only be stored for long periods of time in an environment below 20°C!”
“However, because of Holy Light’s geographical position, although it is never blazing hot, there are still four distinct seasons. The temperatures during the summer can easily reach 40°C, so for the sake of storing these fine liquors, the Duke had built a man-made lake. The purpose of this lake was precisely to control the temperature of the storehouse below it.”
