章 1340: It's Lin Yuelan!

The detector might not be worth much in modern times, but in this era where metals were precious, it was priceless.

That was because that thing could detect where there was a mountain of gold and silver…

However, without a certain amount of professional knowledge, it was impossible to use the probe.

He didn't know if the advisor behind the Second Prince of Black Clouds, Xiao Jingrui, had any ability to study the use of that thing.

"When did Xiao Jingrui come to the Imperial City?"Lin Yuelan was slightly puzzled.

Jiang Zhennan shook his head and said," I'm afraid Xiao Jingrui came to our Longyan Capital in secret in disguise."

Lin Yuelan was still a little confused." When did Jiang Yunfeng hook up with the Second Prince of the Black Clouds Kingdom?"

Jiang Zhennan was silent.
