At that moment, Shen Yue thought of many things.
He could remember every detail about the small stone, and these details informed him that since his childhood up to this present moment, the stone had always remained in its original position.
The same was true for the big stone.
This led him to search the entire cave and yet he had never thought there would be a secret beneath the stones.
In fact, his master, Shizhen, had always been a traditional man, totally unrelated to any kind of advanced technology. This had caused Shen Yue to never associate his master with mechanisms and devices.
But, surprisingly, not only was there a mechanism here, but it was also very intricate and excellent. Even after more than twenty years, it still functioned just as well!
The master hadn't wanted to tell him something on his deathbed. Instead, he had buried a secret when Shen Yue was still his student and only decided to reveal it just before his death?
