It is difficult to get hold of spies from all over the country, and large weapons such as battleships are relatively difficult to get, but infantry weapons are chosen at will, and in the dazzling list of weapons, Zhao Yun chooses the ones he has seen before.

So the above kinds were found, and Zhao Yun's goal was to load the Browning M1921 on the plane. Dual-purpose use to fight airplanes and armored vehicles.

But this is going to run into a troublesome problem, the heavy machine gun is too heavy, and this is not just to be carried on a truck. The machine gun mounted at the front of the plane is too heavy, and the plane is prone to upside down when landing.

In the end, he thought of a way to change the barrel from water-cooled to air-cooled, installed it on the belly of the plane, adopted a fixed installation, and changed the sights, so that it looked similar to the cannon under the MiG plane that Zhao Yun had seen before.

After several test flights, the location of the installation can be basically determined, and Zhao Yun can be regarded as announcing the successful modification of this aircraft.

The first agreement was completed, and the second was the development of a 37-mm rapid-fire gun and a 37-mm cannon for aircraft installation, which was immediately put on the agenda.

This time, Zhao Yun got the 47mm (3-pound) rapid-fire gun (machine gun) manufactured by the French company Haggaeus that had been equipped on the warships of the Beiyang Naval Division "Jiyuan" and other warships, and spent a high price in the Beiyang Naval Division. 20 rounds/1 minute, range: 4575 meters, these numbers look good, but there is definitely something wrong with this gun. Because they were once equipped on every warship of the Russians, but now the Russians have completely abandoned them.

At this time, because domestic steel can't make cannons, Zhao Yun has already sent samples of various types of steel from European steel mills back to China and hoarded them in warehouses. This time, I took it out in one go.

Although the ready-made French cannon is a rotary type, but this firing mechanism can not return the shell, after thinking for a long time, the masters did not come up with a solution, in order to catch up with the progress of the gunners still adopted the principle of the Green gun, in the process of firing, the chamber does not move and the barrel rotates continuously. Each barrel completes the actions of feeding, locking, firing, opening and throwing the shell in turn, but this gun uses a small motor to provide power as the hand-controlled zhì speed of the Green gun.

The rate of fire of the rotary tube gun can reach 400 rounds per minute, and the rate of fire can be adjusted by changing the number of revolutions of the motor, but the main disadvantage of this type of gun is its large size and weight. Because of the problem of the barrel, the ten barrels of the barrel of the gun gun were installed, the diameter of which had reached half a meter, and there was no place to install it in the nose and tail of the aircraft.

Small planes could not carry this big guy weighing more than 600 pounds, so they could only hang a cannon pod under the fuselage of the 400 transport plane, which contained a 37 mm caliber cannon and shells. Shells are fed with magazines, which are loaded on the cannons.

After several tests, the 37 mm cannon installed on the aircraft found the correct position for use, and once the hatch was opened, it fired diagonally upward, because the cannonballs of the cannon were too heavy and began to fall after only 300 meters of flight.

But as long as the other party is next to each other, it is a big hole, during the period of resisting US aggression and aiding Korea, the volunteers used MiG to shoot down giants like B29 many times! It is enough to prove the terrifying power of this cannon!

Moreover, it is possible to enter the attack route from the rear under the bomber by means of a plunder, and flash after the fight, which can completely avoid encountering the bomber's anti-aircraft fire network.

Think about the all-metal fighter planes can't withstand it, and the wooden frame plane is estimated to be able to take down as long as one or two shots are taken.

The effect is good, but this thing can only be mounted on a battleship or a tank, and it is still unreliable for airplanes to use this thing.

Handley Page's 0/400 load is enough, but it is a bomber after all, and when it dives to attack ground targets, it is far away from the shooting accuracy is poor, and when it is close, it will fall headlong after shooting, and it is difficult to get up.

With the French Spad Light Bomb Type XI, the situation was slightly better, but it became a problem for aerial dogfights.

In the end, it cost a lot of money to ask Krupp to help make a special barrel and radiator, which reduced the thickness of the barrel of the gun by half and the weight to 378 kg.

Barely installed in the lower part of a Spad two-seater, tried it on Taihu Lake, used for a ground-to-ship attack, it must be no problem, and the effect is not bad, it should be no problem to deal with airships. However, it is not satisfactory for other aircraft.

In the final analysis, it is still too heavy, and it needs a high-horsepower engine, and this is Huaxia's weakness, and it is a problem that future generations have not been able to solve well, so Zhao Yun can only continue to have a headache.

Therefore, Zhao Yun finally gave up the large-scale equipment, and could only wait for it to be lighter or have a new high-horsepower engine, of course, this problem still has to be solved by Ba Yuzao and others. Because according to the agreement, their second task is only half completed.

For the time being, the aircraft will be equipped with Browning M1921 (12.7mm) heavy machine guns to equip transport aircraft and some fighters to strengthen the force in the air.

The two-horse-drawn chariots of the cavalry in Outer Mongolia were also modified, and the machine guns in the carriages were changed from all Maqinke to half of the carriages were Maqinke and half of the carriages were Browning's heavy machine guns, and the Browning ones were also specially made gun mounts, which could be used for both high and flat purposes, and were suitable for air defense and dealing with enemy armored vehicles.

The arrow towers in various places have also been redeployed, and some of the arrow towers are equipped with anti-aircraft machine guns on the top, and Zhao Yun can finally breathe a sigh of relief against the threat from the air.

The anti-aircraft artillery that the Germans installed on the battleship was also equipped with some equipment by Zhao Yun. The key equipment is Outer Mongolia, and Zhao Yun estimates that the old Maozi of Outer Mongolia will not wait for him to come to the door too safely.

November is the busiest month, although Zhao Yun has found a master of building aircraft and is developing the modification of the aircraft, but he is also busy, because the good news from all over the country continues.

This year, there was a bumper harvest everywhere, and Zhao Yun's French spies collected 7,000 tons of rice from the camp in the French colony of Vietnam, which was then brought into the local mill by the timber bakery, which had grown into a bread chain giant. In other words, the operation in Europe has basically reached the stage of self-sufficiency and providing resources for Zhao Yun's use.

Throwing away this heavy burden of Europe, Zhao Yun is a lot easier, in order to develop the intelligence network, the resources spent are huge! Now that the intelligence network has basically been built, it is time to start harvesting the fruits. The British battleship Zhao Yun has been coveted for a long time, and as an old empire, the army and navy Britain still have a lot of say.

Even if it is difficult to get hold of the British warships in service, then in Scapa Bay, Orkney Islands, Britain, the 52 German warships that sank themselves because of the "Rainbow Operation" were the targets of Zhao Yun's attack.

Of the 52 German warships, 10 battleships and 5 battlecruisers were included. The tonnage of this battleship was enough to rebuild the Beiyang Naval Division.

The bigger result was the establishment of a European intelligence network and the expansion of camps in the Americas, with some people entering the United States through Mexico and others working on local farms.

Timber and food were available in large quantities in South America, and with machinery from Europe, the farms in Brazil expanded faster than the other camps combined.

Of course, the speed of such development is not unrelated to the chaotic social order here, and all kinds of bandit and bandit activities are rampant. Sugar cane farms and farmers who owned more property were the targets of their looting.

However, their weapons were not much better, although some teams also had a small number of submachine guns and light machine guns, but in the face of the rapid development of the Amazon army, with the cooperation of the Mayan feather archers who were good at jungle warfare, the Eagle Warriors, and the Jaguar Warriors, they did not take advantage of anything.

The Eagle Warrior is a class between ordinary infantry and special infantry produced by castles, and is an ordinary class of troops of the Mayan and Aztec tribes. With a short spear, he was able to restrain cavalry who were equally agile in his movements, and compared to other infantry, the Eagle Warrior's ranged armor was surprisingly good, second only to the steel armor of the Gothic Guard. Their armor was made of salt-soaked cotton armor, about two fingers thick, a bit like the cotton armor of the early Manchu cavalry, in fact, this armor was very effective against the impact of swords and crossbows, and many Spaniards who invaded the Americas liked to wrap this cotton armor on their steel armor, so that it was more effective against muskets. As such, he was the pride of the Mayan and Aztec native peoples of the Americas, as he applied a combination of tactics such as sneak attacks, roundabout attacks on ranged troops, and luring their enemies into the ambush circle of the Mayan archers. The Mayan Feathered Archers, on the other hand, were a type of foot archer, but they were only slightly slower than the Eagle Warriors and were very dexterous, especially in jungle warfare, like the elves of Western legends. When facing the enemy, they come and go freely in the sporadic rain of rifle bullets, unless they are strafed with submachine guns. The wooden bow is made of the best wood in the jungle, and it is not inferior to a submachine gun in terms of range. Therefore, after the Eagle Samurai went out to lure the enemy, coupled with the siege of the Mayan Feather Archers and Jaguar Samurai, the basic enemy did not want to leave once he entered the ambush circle.

In order to strengthen their firepower, Zhao Yun also equipped some Mayan archers with submachine guns and rifles, but in the jungle, they were not as effective as the silence of bows and arrows and the ability of bows and arrows to shoot against enemies hiding behind trees.

Among the three major civilizations of South America, the Incas, the Maya, and the Aztecs, the Aztecs were the most barbaric and aggressive people. It can be said that the symbol of the Inca Empire was gold, the symbol of the Maya was technology and the pyramids, the symbol of the Aztecs was force, and the symbol of their military power was the jaguar warriors.

Now let's talk about the military thinking of the Aztecs, who attached great importance to military victory, but they did not rely on killing to win battles, and the Jaguar warriors fought in a very special way: in the eyes of the Aztecs, the status of weapons was different, and the low-ranking warriors used bows and arrows, while high-ranking warriors, such as the Jaguar warriors, used obsidian swords. Their typical way of fighting was to open a long line to approach the enemy, firing long-range attacks as they went, and then the Aztec warriors, the brave and skilled spearheads, led the charge, and the two sides engaged in a fierce white-knuckle battle...... However, it is possible that when the battle is over, the casualties will not be large. Because they did not value the destruction of the opposing party's living forces, the Aztec warriors considered it useless to kill an enemy, and wounded captives were not fit to be consecrated to the gods.

The Aztec warplanes were efficient, and like the Mongols, all boys had to undergo military training. They also had a class of professional soldiers, made up of nobles and brave civilians whose sole duty was to fight. This class is made up of jaguar warriors or eagle warriors, and this class is not hereditary like European knights, but anyone who fights bravely can rise to this class (a warrior can accumulate more than 4 captives, why not kill more than 4 enemies?). This was because the Aztecs were going to take their captives back for human sacrifice, so they tried not to kill the enemy on the battlefield).

The Aztecs revered the jaguar, the king of the South American jungle, as "cautious, intelligent, noble", a powerful animal that was swift and agile enough to dodge incoming arrows before striking down attackers. The warriors wore this tiger skin armor in order to be as brave as the jaguar and gain the strength of the jaguar, and on the other hand, to intimidate the enemy. When you are walking in the jungle and suddenly a person in a tiger skin suddenly appears, your first reaction must be startled. This tiger skin armor can resist certain external damage like the armor of the eagle samurai, and the samurai holds an obsidian sword in his hand, which is a wooden sword with sharp obsidian on both sides, the blade of the stone is sharp enough to be used for shaving, it is glued with turtle feces to hold it in place, and it can be held with both hands. Don't look at it as just a mace-like weapon, but the power is amazing - the hardness of the items we usually use is usually divided into 10 grades, the hardness of diamond is 10, and the hardness of the knife we usually use is 5, and the hardness of obsidian is generally 7, which is 2 grades harder than a knife. According to the records of the Spaniards, it only takes one blow to cut off a horse's head! They were also usually accompanied by shields, which were made of rattan or hardened hard wood, reinforced with leather. Jaguar warriors armed with these weapons proved to be difficult to deal with in white-knuckle combat, suffering fewer casualties than ordinary soldiers, and were able to stun their opponents and capture captives with the smooth side of their obsidian swords. Don't forget to remove the obsidian, they have a big wooden stick in their hands.

So when he was playing against the unruly submarine students of the academy, Zhao Yun just asked them to carry a big stick, knocked all the people who dared to fight unconscious, and gave them a dismount.
