Digging up for treasure

He claimed to have found a temple! An ancient temple! Something that no one knew existed. A place that was not even mentioned in most professional history books. 

How did he find a place that wasn't mentioned anywhere? How could a young man know about such a hidden place? He said he had calculated it. The villagers were mostly illiterate, so they couldn't understand, but the boy still explained to them how he found out that there were some abnormalities in a specific area after reading the records of the unfinished project his father was working on before his death. He said these records were so reliable that they were accepted by the academy and even the organization his mother used to work at. 

Now that he thought about it, wasn't it a little bit strange that his father left this important information at home? The pieces of paper were hidden in between his books. It was only after years of reading that the young man found the research data.
