C821 CIA Secret Base (1/2)

The CIA's branch in the depths of the twenty-metre long secret passage. The moment Xiao Xiu Lian unlocked the door and opened it, he was shocked by the bustling scene in front of him.

The room was not big, only around a hundred square meters. However, in the middle of the room was a gigantic sand table from the Jiang-Nan region. On the surrounding walls, there were countless Military Maps s, corresponding to the latitude and longitude of the sand table.

Zai Chun had already received basic mathematics education, but in fact, in the Forbidden City's Royal Education System, there were already courses on Western Mathematics. At that time, Kang Xi himself was an expert in geometry.

When Zai Chun arrived at the Ryukyu, Xiao Letian especially gave him a lot of math knowledge. He had to make up for it, because if a normal person did not have a foundation in math, even he would not be able to understand Military Maps.

The biggest difference between a Military Maps and a civilian map was that one was more detailed, while the other one had a contour line. In the eyes of a wise man, a 2D map of a flat surface could be formed into a 3D map with a single glance.

It could be said that looking at the military map was the perspective of God. The series of numbers outlined a detailed three-dimensional world.

In a battle between two armies, one side used the 2D map that was previously clear to the public, while the other side used an advanced 3D map.

The generals of the Qing Dynasty had to make preparations in advance so that the horses could feel exactly what was high and what was low on the battlefield. There was also water and forest and shrubs.

The generals who owned the new type of map didn't need to waste such a long time, because the spies had already drawn everything into the map long before the battle had even begun.

They had already deduced the location of the high ground and artillery position countless times on this small map. If they were to snatch the water source and poison it, then they would be able to seize the limelight and set it on fire.

Xiao Letian knew that the only thing that could replace Military Maps s were the future generations of computers. This was because the computer system could truly simulate a 3D map, and with the help of the satellite system, the detailed map was unimaginable.

There was a line of telegraph s against the wall around the information center. They carefully camouflaged their wires and connected them with the telegraph master network through dozens of secret connections. Dozens of telegrams were sent back and forth every day, and the movements of the Jiangnan CIA were controlled by this brain.

When he reached there, Xiao Letian had the feeling that he had just entered the Three Armies Command Headquarters. He was very clear that the current command system of the Ryukyu was not inferior to that of Europe.

Zai Chun childishly pounced towards the edge of the Jiangnan sand table. He first found the direction to the north, then muttered to himself, ”Go north to south, left to west to right, and east to east... This is the west side, which is Shanghai. ”This is the east side, oh, this is Wuhan …”

Zai Chun could understand the military map, but he could also understand the military emblem on the sand table. All of the Xiang Army's troops and defenses were displayed on the sand table.

The names of the Xiang Army Generals and a series of numbers were written on the small wooden tablet and placed at different locations on the sand table. Ceng Guofan's troops could be seen at a glance, all of the defenses in the mountain pass were extremely clear.

As the telegram went back and forth, the temporarily changed defensive information was quickly reflected on the map. The small wooden signs were either inserted in another place or the numbers were erased and written up again.
