This guy again?

Elena was shocked by what Alex said.

With eyes that glowed with intense astonishment, she asked "Did you mean that there's no treasure-artifact buried around the spot we are or in the entire land?"

She asked to be sure of what Alex said.

"The entire land. There's no treasure-artifact buried in it." Alex replied.

Elena's eyes became filled with great surprise. 

"Alex! How do you know that? Don't tell me you scanned the entire place in such short amount of time with some I-don't-know senses. It is impossible for you to achieve such a feat!" Elena told Alex with a loud voice in an unbelieving tone.

"Well, anything is possible with me" Alex said with a proud smile.

Seeing how Alex was sure of himself, Elena then became quiet for a long time. The shock Alex gave her this time around was immense.

Some moments later, she asked "Where do you think the treasure would be or there has been no third treasure?"
