Tehran, November 30, 1943. Pen ~ fun ~ pavilion www.biquge.info

There is a type of well called a qanat.

There are glaciers in the snow-capped mountains, snow and rain in the high mountains, and arid areas below, a climate type from Central Asia to northwest China.

The basic principle of qanats is this.

If there is an abrupt mountain range or peak on the flat ground, three thousand meters, or even higher, then the air currents flowing from above will leave its water vapor on the mountain peak in the form of snow and rainfall. The ground and the ground are still dry and hot, but there is a lot of snow on the mountains. This is true of all the high mountains in the world, which is why the high mountains and plateaus are the so-called water towers.

In spring and summer, a large amount of snow and rain flows down the valley and dives under the Gobi Desert. Taking advantage of the slope of the mountain, a series of wells are drilled down to draw water from the underground aquifer, which is connected underground and leads water to low-lying areas to irrigate farmland.

The first advantage of qanats is that they are not afraid of heat, wind, and water. The surface channel is exposed to the wind and sun, and the water loss is huge. Qanats won't.

The seepage loss of water in the surface channel is very large, and the qanats will not, because the qanats are mainly underground, and the elevation is basically above and below the groundwater level, so there is no loss of water. If it is below groundwater, the amount of water is also replenished.

Another benefit of qanats is that they ensure artesian irrigation. The farmland is in a low-lying area, far from the sand and gravel gathering place in front of the mountain. If you build an above-ground channel, the amount of work is very large. The underground channels were built once and for all, with a proper slope, and the water and wine did not need any power, and under the action of gravity, they flowed into the distant farmland on their own.

The desert soil is fertile, and there is no shortage of sunlight. With enough water, good crops can be produced.

The number and length of qanats in China are miraculous.

Walking in the qanats, if it is daytime, it is not dark inside, it is an earthen cave inside. The earth cave is very high, and people can move freely in it. If the soil is soft, it should be supported with wood. In the middle of the low part of the earthen cave is a canal, and on both sides of the canal is a pedestrian road. The qanats need to be constantly repaired, and the pavement is for maintenance.

The so-called maintenance is to scoop out the mud in the well and drain it through the shaft. If the wall of the well and the earthwork of the well canal are prevented from collapsing, they should also be supported by columns. Some wells are so old that you can't see the appearance of the well, they are extremely wide, and there are even trees growing at the bottom of the well.

In arid areas, qanats, and even underground waterways, are innovations that people have learned from survival.

In the "Historical Records", it is called "well canal", which is the most accurate name. It is called kanatz in Xinjiang and kanatz in Iranian Persian. In Russian, it is called Kanyaliz, and there is not much difference.

The point is that Iran also has qanats.

Tehran is located in the southern foothills of the Alborz Mountains, which are more than 3,000 meters high, and the Caspian Sea is in the north of the mountain range.

Tehran is relatively arid, and its water supply depends entirely on qanats and streams formed by snowmelt in the mountains.

Especially in the forties, there were also qanats, and the snow from the qanats watered the vegetable gardens in the suburbs. In addition, Tehran's sewers and water supply also have traces of qanats.

On the morning of the 30th, Xiaolu drove to the northern slopes of Tehran with a local, an interpreter, and a guard. On the hillside, the trail holds a map and compares the terrain of Tehran.

Looking at it, Xiao Lu saw some doorways, he saw where there might be a qanats, and asked the interpreter to ask the guide, and sure enough, the guide affirmed Xiao Lu's judgment.

So there is a qanats just near the British Embassy?

Yes yes.

What is that clearing?

Necropolis of Armenians.

Understood, go, I'll take a look at the cemetery.

There are abandoned houses in the cemetery, which are the houses of the cemetery keepers. There are several wells in the cemetery, very deep wells. The path can be clearly seen, there are traces of ropes at the mouth of the well, and it can even be seen that there are ladders under the well.

Leaving the cemetery, it was already noon, the late autumn weather was very dry, the road was rough, cars walked by, and there was a cloud of smoke and dust.

There was another cloud of smoke and dust on the south road, and it was a car, no need to ask. The two cars met, and the path looked into the car, and it just so happened that the people in the car also looked into the road. The eyes of the two sides met in an instant, and it seemed that both sides understood each other.

Sitting in the car across from him was a white man, wearing a hat, his face unclear, but Xiaolu clearly felt his gaze. Koji's intuition led him to be the head of a German spy.

Returning to the station, the delegation had already gone to the Soviet embassy.

Xiaolu rushed to the Soviet embassy, where five delegations were holding informal meetings because of the bombing incident, and many things had been agreed.

Xiaolu and Zhou Gong quietly discussed for a long time, and Zhou Gong proposed to several other delegations the plan for tomorrow's meeting, and the meeting at the Soviet Embassy would remain unchanged, and it would be unusual. Secretly send a convoy to the British Embassy, and so on.

Several delegations, which were having a headache, listened to the suggestion and thought it was good, and they all agreed.

December 1, 1943.

In the morning, several countries simultaneously announced that today's meeting would be held at the Soviet Embassy, and the reporters were waiting in a designated place, and when the press was open for interviews, there would be a car to pull the reporters to the Soviet Embassy. The Government of Iran provided cars for each delegation, as well as soldiers in the cars to serve as guards.

At the same time, the road to the British Embassy was sealed for all delegations. At ten o'clock in the morning, the delegations, under the protection of the troops, came to the Soviet embassy one after another.

At half past ten, a dozen cars quietly drove into the British Embassy. When the Chinese delegation left, everyone did not see Zhou Gong clearly, but only saw a person wearing Zhou Gong's clothes enter the car. However, the people around saw it clearly, and after looking around the path, the last one entered the sedan. Moreover, the sedan slowly drove to the British Embassy.

In the past few days, anyone who has followed the Tehran meeting knows that Xiaolu is the second person in charge of the Chinese delegation, and wherever he goes, the meeting will be held there.

As soon as the Chinese delegation's vehicle entered the British Embassy, the embassy door was closed. The British embassy was heavily guarded, and the movement inside was not clear at all.

Xiaolu saw that the gate was closed, so he got out of the car, and the old wolf wearing a Mao suit and combing his back also got out of the car, and whispered: "How can you fight in a Mao suit?" I'll change it later. ”

Xiaolu said: "Maybe wait a little while to enter the sewer, this suit is very suitable." How do you wear military shoes? Not a match at all. ”

The old wolf said: "If you wear leather shoes, how will you fight later." ”

The two walked briskly into the conference room.

This time, Koji's plan was to give the German spy the impression that the meeting was still being held at the British Embassy, but it was just a trick to deceive the German spies.

The real delegates to the conference were all in the Soviet Union, and the people who came to the British embassy were security personnel disguised as leaders. Because only two cars came from each delegation, there were not many people, only about 30 security personnel. After a while, some people had to be quietly evacuated, and only a dozen or so security personnel were to carry out the plan to eliminate the most powerful German spies at the British Embassy.

The plan is made by the path, and naturally there is the path to direct the implementation.

By noon, the British and American security personnel had already left, and the French had left only two.

The trail and the Soviet security personnel were already led by the personnel of the British embassy and found the sewer system.

The British embassy happened to be built on a qanats, through which sewers and water supply pipes passed.

When I entered the qanats, I realized that the underground tunnels here were more complicated than I imagined. Because of the needs of urban construction, two underground passages were added to the main road of the original qanats, one of which led to the cemetery, and one of them was very narrow, and people could only climb through it, so there was no iron fence, which was a loophole.

The sink has an exit in the kitchen, and you can go through two doors to the conference room. Because of the meeting, the kitchen is not used these days.

Soon, the people were set up, a few people were arranged in the conference room, a few people were arranged in the kitchen, the tape recorder played the sound of different people talking, and everything was set up.

The path was in one of the hallways of the conference room, waiting for the arrival of the Germans, like a spider waiting for a flying insect.

Xiao Lu sat on a chair, covered with an overcoat, his eyes closed, he touched his body armor with his hand and decided to sleep.

It's a rare break from the trail.

Except for the recordings played by the tape recorder, the embassy was very quiet.

December 1, 1943. 12 noon. Cemetery.

Li Shun, Three Foxes, Sultan? Three of Armazov were ambushed in the cemetery, and two other Soviet agents were ambushed in the distance from the cemetery.

The location of the three of them was the house of the cemetery caretaker.

The Soviet agents had a good nose, and they also smelled the conspiracy of the Germans, and listened to the Chinese's proposal to come here to arrest the Germans, but without saying a word, they agreed to come with their intelligence.

At 2 p.m., a truck drove out of the city, the car stopped at the cemetery, and eleven people jumped out of the car. The ten men were all dressed in civilian clothes and armed with pistols. After looking around for a while, and with peace all around, they came to a well. One of them lowered a long rope and was about to go down.

At this time, one of them stopped them and said a few words to the two of them. This is a person who can be alerted.

Four men pulled out their pistols and walked towards the dilapidated house where the cemetery was guarded.

Four men entered the house from both sides and began to search. The house was dilapidated, half of the roof was gone, most of the walls had collapsed, and a low section of the wall under the windows remained.

The four of them searched carefully and saw that there was nothing unusual, so they left the dilapidated house.

Eleven mermaids rushed in and drilled through the wellhead.

The cemetery was calm again. The strong sunlight shone on the loess of the cemetery, as if it were summer.
