"Boom~"

There was another thunder.

This time Lin Feng heard clearly.

From under the ground, there were waves of echoes.

Lin Feng closed his eyes and judged the location, size, and shape of the underground space based on the echo...

Ten minutes later, through the echo caused by the thunder, Lin Feng constructed a three-dimensional three-dimensional figure in his mind.

Last time when I was digging for gold buried in my childhood in Myanmar, a master named Wei Wu demonstrated this skill.

But compared to Lin Feng's hearing, Wei Wu was far behind.

Later, whenever he thinks about this, Lin Feng will train himself to use his hearing to judge the size, location and other data of various spaces.

Lin Feng has accumulated a lot of experience through constant training this year.

"Boom~"

There was another explosion of thunder.

Lin Feng heard the sound of metal objects colliding.

Not an ordinary metal, but gold!

More than 300 meters underground, there is an underground space with an irregular shape, hundreds of meters long and tens of meters wide.

There's a lot of gold in it!

"What's wrong?"

An Qi finally couldn't help but ask.

Lin Feng took a deep breath and said calmly: "I heard strange sounds coming from the ground."

An Qi smiled slightly, "Are you looking for an excuse to divert attention?"
