章 706: Chapter 685: The Secret of Half a Century

Zhong Cheng listened to Lin Ju's narration and slowly started to see the beginning of the story:

In the 1950s in America, most wilderness areas were still uninhabited, and Guo Xiao, who loved exploring nature, stumbled upon this huge unidentified object by chance.

Initially, he thought it was just a peculiar rock, but the keen perception of an aviation engineer quickly made him realize it was extraordinary, with many exceptional features evident from its refined exterior.

"Karst Black Stone," this was how Guo Xiao first referred to it. He treated the object as a collectible, storing it in his garage and even hoping to make some money by exhibiting it.

However, one day before he could take such action, while Guo Xiao was adjusting his black-and-white TV set, he encountered some mysterious interference.

After careful adjustments, he eventually found that it was a high-frequency signal, frighteningly powerful, as if he had installed an antenna in his own home.
