Deep in the more than 20-meter-long secret passage was the CIA branch in Jinling. The moment Xiao Xiumian unlocked the combination lock and opened the door, Zai Chun was stunned by the lively scene in front of him.
The room is not big, just over a hundred square meters, but there is a huge sand table of the Jiangnan region in the middle. There are countless military maps on the surrounding walls, corresponding to the longitude and latitude on the sand table.
Zai Chun had already received basic mathematics education. In fact, in the royal education system of the Forbidden City, there were courses on Western mathematics. Kangxi himself was a geometry master at that time.
After Zai Chun arrived in Ryukyu, Xiao Letian specially provided him with a lot of mathematics knowledge. It would be impossible if he didn't do it, because if ordinary people don't have a foundation in mathematics, they can't understand military maps.
The biggest difference between military maps and civilian maps is that one is more detailed, while the other has contour lines. In the eyes of a knowledgeable person, a flat two-dimensional map can create a three-dimensional topographic map in the mind at a glance.
It can be said that looking at a military map is completely from a God's perspective, and what the string of numbers outlines is a detailed three-dimensional world.
When the two armies were fighting, one general used the two-dimensional map of the Qing Dynasty, while the other used an advanced three-dimensional map. The outcome of this battle was already clear before it even started.
The generals of the Qing Dynasty must make preparations in advance and let Tan Ma find out where is high and where is low on the battlefield, where is the water source and where are the forest shrubs.
Generals with new-style maps don't have to waste such time at all, because espionage personnel have already drawn everything on the map before the battle begins.
Where to seize the high ground first, where to place the artillery positions, how to seize the water source and poison it, how to seize the limelight and set fire, have been deduced countless times on this small map.
Xiao Letian knew that only later generations of computers could replace military maps, because computer systems could truly simulate three-dimensional terrain maps, and with the help of satellite systems, those terrain maps were so detailed that it was unimaginable.
There is a row of telegraph machines against the wall around the intelligence center. Carefully disguised wires are hidden in the walls of private houses. They are connected to each other through dozens of secret interfaces and the main telegraph network. Dozens of telegrams are passed back and forth every day. Every move of the Jiangnan CIA All are under the control of this brain.
When Xiao Letian came here, he felt as if he had entered the tri-services headquarters that was full of science fiction in later generations. He knew very well that the current command system in Ryukyu was no less than that in Europe. If compared with the backward Qing Dynasty, everything in front of him was actually a movie. Science fiction blockbuster.
Zai Chun childishly rushed to the edge of the Jiangnan sand table. He first found out which direction was north and then muttered, "Up north, down south, left, west, right east... This side is the west, which is Shanghai... This side is To the east, oh this is Wuhan..."
Zaichun can understand military maps, and of course he can also understand the military symbols on the sand table. All the Hunan Army's military deployments have been displayed on this sand table.
The names of the Hunan Army generals and a series of numbers were written on small wooden signs and inserted in different positions on the sand table. Zeng Guofan's troop deployment was clear at a glance, and all the pass city defenses were clear.
Telegrams were passed back and forth, and the temporarily changed defense information was quickly reflected on the map. Those small wooden signs were either inserted in different places, or the numbers were erased and written on top again.
Gradually, Zai Chun's excited face turned lonely. "Master, no wonder you don't want to train too many soldiers. With such a strong intelligence network, if you are given an army of 40,000 to 50,000 soldiers, you can defeat the Hunan Army of 500,000 soldiers." The army."
"Don't talk about you, even I have found countless loopholes in the sand table. As long as the intelligence is in your hands, the army can find every opportunity on the battlefield, lead the enemy by the nose, and drag down the elite soldiers into tired soldiers. Harass the tired soldiers into weak ones, and finally annihilate them with all your strength..."
Xiao Letian put his arms around Zai Chun's shoulders and said, "Learn slowly. Technology is not the strong ships, guns, steel and textiles that you can see...the soft power in many places is very scary, such as the popularization of telegraph lines." , destined to change the entire pattern of war..."
"Mathematics, physics, chemistry... all kinds of subjects will intensify the changes in the world. If a country wants to stand among the nations of the world, it depends on its comprehensive strength... Let's go and see the city of Jinling Landowners, it’s time to give them a meal.”
After walking through the command center and bypassing two small secret passages, a group of people got out of a cabinet in the study room. Only then did Zai Chun realize that the secret passages had opened up many private houses. Many ordinary people's homes are the footholds of the CIA.
After walking around and walking through a crack in the wall, I opened the secret door and found a storage room filled with rice noodles. The beams were hung with bacon and various baskets. Xiao Letian stretched out his hand from the jar at the foot of the wall. He actually took out a preserved egg and handed it to Zai Chun, "Try it. I'm afraid few people in the palace will give you this..."
This is actually the storage room of a restaurant. After Xiao Letian and the others walked out of the house, they were in the backyard of the restaurant. The boss and the waiter had been waiting here for a long time. When they saw Xiao Letian and Zai Chun, they kowtowed without saying a word.
The big shopkeeper's words were filled with tears and excitement, and he couldn't say anything right. "Sir...please...the third floor has been cleared, and the distinguished guests are waiting for you, um..."
The group of people climbed up the stairs, and finally at the door, only three people, Xiao Letian, Zai Chun and Hu Xueyan, pushed open the door and entered, while the others stayed outside.
In the warm private room, as soon as the brilliant Zeng Guofan and Zeng Guoquan saw Emperor Tongzhi, they immediately stood up and knelt on the ground three times and nine times. If it weren't for the inconvenience of talking here, they would probably have roared.
"Old minister, I see your Majesty, long live my emperor, long live, long live."
"Pingsheng, you two love me." Zai Chun rushed to help the two of them. After Zeng Guofan stood up, Xiao Letian was about to speak and Marshal Zeng fired at him.
"Xiao Letian, it is an honorable thing for you to take His Majesty to study. Why are you so secretive? Could it be that the Emperor cannot come to Jiangnan? Why don't you display the Emperor's guard of honor?"
"White Arowana Sui, if anything happens, my 500,000 Hunan Army will never let you go."
Looking at the angry Zeng Guofan, Xiao Letian shrugged, "Okay, okay, Marshal Zeng, please calm down first. You know better than me what's going on in the imperial court now. If Your Majesty comes to Jiangnan with great fanfare, is it really okay? In Beijing, Those people will agree...Don't get angry at me yet, it's been a long time since I saw His Majesty, and you still haven't caught up with me."
"Hmph, I'll settle the score with you later..." These five figures in the Qing Dynasty, who could make the whole country tremble when they stamped their feet, finally sat together and had a dinner that affected China's modern history.
