Even at half past eight in the morning, the sea was still covered with fog, and in order to avoid irreparable damage caused by the collision of ships shrouded in dense fog, two seaplanes carrying radios took off from the Notoro seaplane carrier and rose several thousand meters into the air to guide the ships moving on the sea in the dense fog with very low visibility.

On the Shanghai side, after expanding the patrol area to an area of 800 kilometers, dozens of high-altitude unmanned reconnaissance planes dispatched earlier discovered at 9:11 a.m. that nearly 100 large and small ships with flagpoles flying the Rising Sun flag on the sea were rushing violently toward Hangzhou Bay.

Due to the technical limitations of this era, there is no way for the seaplane to fly to a height of nearly 10,000 meters from the high-altitude unmanned aerial vehicle, and the seaplane responsible for leading the way was not aware of the fact that there was a surveillance overhead, but flew in the direction of 600 kilometers away from Shanghai.

Nearly a million residents of Shanghai and its surroundings lined up in countless queues to enter the huge underground bunkers in an orderly manner under the guidance of the Tuqi Marx chariot that maintained order, and the various wharves in Shanghai and the empty Zhoushan Islands were already covered with dozens of huge self-propelled batteries that had been waiting for them, and these giant beasts aimed their thick 800-millimeter electrothermochemical main guns in the direction of attacking the enemy, as long as the general command gives an order, the invading enemy will not return.

In the places where the Japanese troops on the front line of Hangzhou Bay were likely to land, the Workers' and Peasants' Army, which had increased in strength and had a total strength of 350,000 people, built one powerful anti-landing defense line after another with the help of automatic trench digging machines provided by Zhao Heng and a large number of prefabricated components of various bunker firepower points transported by a large number of military heavy trucks.

In addition, several hundred planes of the First Air Combat Brigade of the Workers' and Peasants' Army, including fighters and bombers, that arrived at Hongqiao Airport were ready to set off anywhere and reach the combat airspace to engage in a desperate contest with the enemy's air fighter units.

At this time, in addition to building anti-landing sites along the Hangzhou Bay, the Workers' and Peasants' Army also occupied favorable buildings in the entire urban area of Shanghai, blocked the stairwells and windows of various buildings, and used the powerful transport capacity of dozens of Mi-24 armed transport helicopters newly built by the Red Police Base to transport all kinds of ammunition, materials, weapons, equipment, and fighters between various strongholds.

In order to be on the safe side, Zhao Heng produced several base vehicles, one of which was placed in a hidden place two hundred kilometers away from the front line of Hangzhou Bay to establish a base, after the base car was deployed, several electromagnetic power plants and solar power plants were built, and then four light and heavy factories were built to produce various weapons and equipment and ammunition for front-line soldiers. The anti-aircraft artillery is to deal with the attack of the enemy's sky fighters, and in order to offset the enemy's long-range firepower, a large number of French cannons with a caliber of 280 mm were specially built in "Red Alert 2 Yuri's Revenge", and a large number of laser towers and electromagnetic coil towers were specially built in order to deal with the infiltration of the enemy's small forces and spies.

The other three are located in the suburbs not far from downtown Shanghai to build bases, and the same but a large number of defensive buildings have been built like the Hangzhou Bay front-line base, light and heavy factories have been built an astonishing dozen, and electromagnetic power plants and solar power plants have been doubled, so Shanghai's materials are continuously transported into the underground bunkers and defense bases in the urban area through the low-altitude transportation of tactical aircraft.

For Zhao Heng, these are nothing, what is even more crazy is that he copied the anti-aircraft fortresses known as G Tower and L Tower built by the mustachioed Führer of Nazi Germany in Berlin at the end of World War II.

The fortress turret built by Zhao Heng has an anti-aircraft function - this is the so-called "anti-aircraft turret". (German: flakturm, English: flak-tower)

The construction of the anti-aircraft turret was based on the pre-war ideas of Dr. Elmar Wiedmann, an authority in German architecture. According to its idea, eight 30-meter-high anti-aircraft towers were to be built near the railway station in Munich, an important town in southern Germany, in order to cope with enemy air raids on important German targets in future wars.

However, the bureaucracy of the Third Reich at that time did not fully realize the real threat of bombers, and this plan was not approved. Later generations improved on its conception, which evolved into the later anti-aircraft turret.

In terms of the functions they played, there are two types of anti-aircraft turrets that were actually built: the G tower and the L tower

The fortress fortress of several super G turrets was built on various main roads in downtown Shanghai, and its length of 140 meters, width of 140 meters, and height of 70 meters is the largest known among the large towers, and its top has been equipped with eight 128 anti-aircraft guns, as well as 37 machine guns and a number of 20 machine guns for defense. In terms of personnel, there are usually twelve officers and two companies of three hundred and twenty enlisted men.

And its matching building super l tower (leitturm = command tower) is also next to each other, with a length, width and height of 100, 50, and 80 (meters) respectively, which is relatively a small tower. It is mainly equipped with radar and various shooting and aiming calculation instruments, and is also equipped with 20 machine guns for defense. The staffing is basically the same, and the number of soldiers is slightly less than that of the G tower.

Therefore, as a rule, both towers are combined as one actual combat unit. The combat tower is responsible for air defense, and the conning tower not far away provides it with data

In addition, in addition to air defense missions, because the anti-aircraft turret is a reinforced concrete structure, the outer wall thickness reaches more than two and a half meters, and the top thickness is usually more than three meters, which is extremely strong enough to withstand ordinary air raids, so its interior is usually used as a refuge for ordinary citizens or other temporary places for public facilities.

Of course, the first purpose of the existence of these anti-aircraft turrets is anti-aircraft defense. According to the designer's concept, even if it is impossible to shoot down incoming enemy aircraft, the anti-aircraft turret itself is a threat to enemy aircraft, which can prevent air strikes to a certain extent.

At a distance of four hundred to five hundred meters from it, a tower was set up. Since there were no anti-aircraft guns on the L tower, only ordinary anti-aircraft guns, the building was relatively small.

Relying on the data transmitted from the radar of the L tower, the anti-aircraft guns and machine guns of the G tower could conduct accurate fire. In addition, in addition to being equipped with light anti-aircraft guns for self-defense, the tower is usually equipped with a listening machine and a searchlight to capture enemy aircraft more effectively.

The light anti-aircraft guns of the G tower are usually mounted at the four corners of the top of the tower, at a distance from the anti-aircraft guns. On the one hand, it is to not affect the use of anti-aircraft guns, and on the other hand, it is also to protect itself from the sound and impact of anti-aircraft guns when they are fired. Use the automatic lift when returning. In addition, below the top platform are the gunners' standby room, living quarters, operation room, ammunition room, etc., which are kept at a certain distance to avoid shock wave interference when firing anti-aircraft guns.

At the top of the tower there was a circular flat platform with a diameter of ten to fifteen meters, on which a searchlight and anti-aircraft guns for self-defense were located. The superstructure of Tower L is basically the same as that of Tower G, with the same waiting room, living quarters, and operation rooms. The reason why the two towers had to be protected was that the weight of the anti-aircraft guns reached thirty tons, and the recoil force of their firing would reach about twenty-five tons.

The thickness of the outer walls of the anti-aircraft turret reached more than two and a half meters and was applied a mixed camouflage of gray + green.

Internally, it is usually five floors, excluding the basement. Each floor is connected by a spiral staircase, and an automatic lifting device is used between the top and the top. There are two automatic lifting devices, which can be used to transport wounded soldiers in addition to military and cargo handling.

The internal layout of the G tower is usually as follows:

The first floor is a civilian anti-aircraft shelter with separate power and water supply facilities;

the second floor serves as a temporary repository for art galleries and museum collections;

The third floor can be used as a temporary hospital, with nearly 100 beds and two operating rooms, with eight doctors, 20 nurses and 30 assistants;

The fourth and fifth floors are usually the soldiers' quarters, as well as the army headquarters, the wireless department, the Gestapo branch, etc., so that they can climb to the top of the tower at any time and participate in the air defense battle.

This turret has its own separate water tank and power generator, as well as a large loaf baking facility. Theoretically, even if Germany surrendered, the anti-aircraft turret in Berlin could hold out for another year or so.

The construction of such a structure would be a nightmare for the Japanese intervention forces and their allies who tried to occupy Shanghai, and the construction of such a defensive structure was also a forced choice.
