General Manor
Lin Yuelan opened the backpack she found in the basement and found some cosmetics. Then, she opened a small zipper inside and rummaged through it. She found two maps inside.
Lin Yuelan was not clear about the geographical situation of this era.
Therefore, she raised her eyebrows slightly when she saw the map and handed it to Jiang Zhennan.
Jiang Zhennan looked at the two maps and frowned slightly. Then, he said very honestly," Yue 'er, I don't understand!"
Lin Yuelan was a little confused," You don't understand?"
Then, she took the blueprint and understood why Jiang Zhennan couldn't understand it!
Because this map was marked according to geographical coordinates, the angles and slopes were clearly recorded, so it was understandable that they could not understand it!
Lin Yuelan explained," This is a kind of geographical coordinate mark. It records the coordinates in degrees of latitude and longitude!"
