Why didn’t General Wan Xinghan brilliantly submit the map?

Greedy for money. "Brilliant Star" is a legendary costume drama starring Wu Lei and Zhao Lusi. The drama will be broadcast online on Tencent Video on July 5, 2022. The map General Wan took was the "Kanyu map", also known as the Feng Shui map. It is a map depicting the relationship between the Feng Shui geographical conditions and planning layout of tombs, residences and city sites. The reason why General Wan didn't hand over the Kantu Map to Ling Buyi was because he thought it was a treasure map. It was because of his greed for property that he didn't hand over the Kantu Map.
