The so-called knowing oneself and knowing one's opponent can win all battles, and there is no written information that is more practical than what you see with your own eyes. Although the eye cannot guarantee that everything seen is correct, it can be recorded in one's mind as direct evidence, and human witness is the most important evidence in any case.

With a population of 1.2 million, West Berlin occupies more than half of the urban area of Greater Berlin, which is 62 percent of the size of the whole of Greater Berlin. It has its own city government, but it is under the supervision of the occupation forces of the United States, Britain and France.

"Across the road is the range of West Berlin?" Serov saw a warning sign on the opposite street, and the soldiers on both sides were facing each other from a distance, not to mention the sabre-rattling, but there was no warmth.

"Yes, Comrade Serov, West Berlin in the occupation zone of the Three Kingdoms uses the currency of West Germany, and the dollar can also be used as a currency!" The person who spoke was Serov's comrade, Adal Bet, head of the German Stasi Technical Supervision Department. However, the real identity of this person is an investigator of the Adviser Department of the First General Directorate of the KGB in East Germany, and his nationality is the Soviet Union, but he is a minority in the Soviet Union, a Volga German.

"Really? That's a terrible thing! Serov's eyes on the other side were uncertain, any confrontation on the surface could be prevented, but this invisible infiltration was the most terrifying. In Serov's eyes, West Berlin, which was located in the territory of the GDR, was a cancer that absorbed the nutrients of the GDR and even Eastern Europe, and the longer it went, the more malnutrition would become in the countries of Eastern Europe.

At present, the Berlin Wall does not exist, and there is nothing to stop Serov from looking at the other side, and it is very normal that cars flying the flags of the United States, Britain and France disappear from time to time not far away, and part of the reason for the recent Berlin crisis is that the three countries want to keep their troops able to patrol the whole of Berlin.

"Today I'm going to take a closer look at the outposts that surround West Berlin, by the way, is it the People's Army or the People's Armed Police Force patrolling?" Serov, who was sitting in the back of the sedan waiting for departure, asked.

"It's a people's armed police force under the Ministry of Internal Affairs!" Adalbert motioned to the driver in front of him to drive, and said, "Even if we patrol day and night, we still can't organize the exodus of the East German people, which makes us very embarrassed when facing the other side......

"Who made the Americans rich, there is no way, who let the main battlefield of World War II be in Europe? The United States won the world war by killing 400,000 soldiers, and even Azerbaijan paid more casualties than the United States! If it was reasonable, the Iron Curtain should not have appeared! Now because of the Berlin crisis, the motherland is scolded by those mouthpieces every day, and those heads stuffed with don't think about who ignored the demands of the Soviet Union and couldn't wait to form the Federal Republic of Germany? When we established the GDR defensively, it became a disregard for the feelings of the German people? Serov said these words in a playful tone, "If we were really reasonable, our relations with the Americans would not be like this!" So I'm not going to reason this time......"

Serov spent three days walking through all the checkpoints, followed not only by the KGB members who had been brought from home, but also by the military staff officers of the Western cluster of the Soviet Red Army in Germany, after all, he was not a professional soldier, and he needed these professionals to make a correct judgment.

"There are two reservoirs in the precinct of West Berlin, which were dammed by the rivers Spree and Javel!" The Red Army staff officer who followed Serov with a high-powered telescope said, "Two reservoirs are enough to supply a million people in West Berlin!" ”

"Is there still one sewer and electricity in the whole of Berlin?" Serov asked meaningfully.

"Yes, after all, it is a whole city, and we are not separated from the United States, Britain and France!" Serov's question was answered in the affirmative by the staff officers of the Western cluster.

That's it! Serov smiled uncertainly, "Okay, that's all for today's inspection!" I also want to go back to the garrison to think of a way, thank you Red Army comrades for accompanying me for a day of idle strolling today......"

The inspections of the past few days were not fruitless, and Serov saw something unusual, that is, a considerable amount of building materials piled up in some places, including masonry, steel and barbed wire! This shows that Serov's German counterparts are making some preparations behind the back of the Soviet Union, and as long as the situation develops to the point where the Soviet Union can no longer sit still, the GDR waits for the Soviet Union's nod and approval, and the historical Berlin Wall can be quickly completed in a short time.

Historically, Khrushchev was surprised by the rapid completion of the Berlin Wall, and the fact that it only took such a short time to complete such a large project shows that the GDR had already prepared for this purpose.

Serov took a cold look at the development of this matter, and the Germans themselves could afford to make such a determination, and he, a Soviet man who had no stakes, naturally did not care. Serov came to Berlin not only to be a contractor, but also to repair the wall, he only needed to make a suggestion, and he didn't need to come in person.

The reason why the Soviet Union was in a relatively difficult position in the Cold War was because the Soviet Union was far from recovering its pre-war strength just after the end of World War II, and the United States, which had not been hit on its own territory, forced the Soviet Union to fight in a disadvantaged situation, and it had no time to maintain a confrontational situation without even having time to develop its economy. Even the Soviet Union, as the big brother of socialism, is facing the war while developing, not to mention the fraternal countries on its side that were hit hard in World War II.

As for the situation in Berlin, the United States, which has deep pockets, used the Marshall Plan to support the recovery of these countries, allowing those countries whose foundations were much stronger than those of Eastern Europe to recover quickly, creating a contrast with the Soviet Union.

As a result of the Cold War, some people often use capitalism's victory over socialism as an argument, ignoring that the struggle was unfair from the beginning, and that the result was not the victory of capitalism over socialism, but the victory of a group of countries that were already imperialist powers over the Soviet Union and a group of poor countries, which were barely considered poor countries.

On Serov's desk that night, a map of Berlin's circuit network and a map of the city's sewer network, a statistical map of Berlin's annual rainfall, and a map of the rivers around Berlin appeared: "It's too easy to build a wall, I want to make West Berlin a dead city, a stronghold that will make the other side bleed, and if you want to continue to occupy it, you must pay several times the price now......

West Berlin is like something that should not be in the GDR, and to use the metaphor of a nail in a planning area, Serov has to cut off water and electricity, divert the two rivers that flow through Berlin, replan Berlin's electrical network, and rebuild underground waterways, not just repair the walls.
