Because there were many hands on the excavation team and Leonard Ethan used his extraordinary powers to change some of the underground conditions to facilitate the work, they reached a depth of over 5 meters after more than 20 days of digging and found the historic city wall ruins.
The reason the excavation took longer was that as a team of professional archaeologists, they needed to carefully clean each layer and take detailed records before proceeding to the next.
After eating lunch that day, Leonard and Joan each picked up a metal detector and jumped into the newly excavated layer to start prospecting.
Since Leonard only had a few scattered memories in his mind, he had no choice but to search slowly. However, compared to Schliemann, he at least had a metal detector, which made the search much more efficient.
