For Leonard and his group of people, discovering the Orient Express was much more valuable than finding the World War II Golden Train. The Golden Train would be considered looted goods, with no need to be handed over and without any economic compensation.
On the other hand, these carriages became unclaimed property due to a series of post-war compensations and agreements. So, after Leonard honestly obtained legal excavation permits, the carriages belonged to him as the discoverer.
So, Leonard had a good night's sleep that night. On the one hand, this was because everyone was very tired after spending several days outdoors. On the other hand, it was due to the joy brought by their huge harvest.
Of course, taking advantage of this opportunity, Leonard also checked the cards he obtained this time before going to bed. Compared to the cards obtained before, this time the cards were not as magical, but they were definitely not lacking in practicality.
