The economic development of Yan is not slow among the other six countries. At least. They have their own iron works in Liaodong. Coal mine base. This coal and iron were transported in large quantities to the northern steel base of the Qin State. At the same time, there are also medicinal herbs, such as ginseng, or something. There is also a lot of leather, wood and so on. The paper industry in Yan is also relatively developed. One-third of the paper in the Qin State was made in the Yan Kingdom. Most of the paper demand in the six countries comes from Yan. Because Yanguo not only has large-scale papermaking equipment. There is also a large amount of primary deforestation.

Other countries are doing it because they don't have the technical equipment. For example, the state of Chu in the south. They can't produce paper because they don't have the technology and equipment to do so.

Generally. Yan still has a few things that can be used for the development of the national economy and industry. But economic development is inseparable from management. Yan's economy clearly lacks the proper management. In particular, in order to satisfy his own selfish desires, King Yan frantically taxed these enterprises. This puts a heavy burden on these companies. It is difficult to have long-term development. In particular, they don't have enough money to scale up their businesses.

And the worst things can happen to these businesses. It is the fact that these business operators have difficulty obtaining some of the major infrastructure guarantees. Especially a guarantee system like the one in the Qin state. The reason why the Qin State developed rapidly. In addition to being lightly taxed. There is also the huge investment in public facilities. Like what. Large-scale railway construction. The state of Qin was completed by competitive bidding. There is also a network of highways. and urban water systems. Sewer system. There is also the Qinguo urban power network system. In order to provide lighting for Xianyang, the first city with a population of more than one million. The Qin State also vigorously developed public lighting systems. The impact of this system is: It is very convenient for the people of Qin to stay and work in Xianyang, Qin State.

And these government inputs. It has also stimulated the development of many economic industries. For example, the construction industry of the Qin State. Qin's cement and steel production grew rapidly. Not only is the yield fast. It also led to the leading construction technology of the Qin State. The advent of cement pouring technology has made it possible to complete buildings more quickly. And the quality is good, too.

It's not just about construction. Then there's the power generation industry. Qin's power generation industry developed rapidly under the stimulus of Qin's public lighting system. A series of power plants were built. The scale of power generation is getting bigger and bigger. And the power of the generator is getting bigger and bigger. In addition to power generation. There is also the manufacturing industry of lamps and wires in Qin. They are in order to get government orders. It is bound to increase innovation efforts to make the development of electricity in the Qin State faster.

Arguably. Behind the rapid economic development of the Qin State is inseparable from the painstaking management of the Qin people. In particular, the Qin people invested a lot of money to obtain the expected results, which were all originally deserved by the Qin people.

Opposite. Yan Wang's inaction. In particular, the frenzied taxation of taxes has caused a great burden on the economy of Yan State. This burden has a significant negative impact.

Yan not only has a need for war. At the same time, there are also the personal needs of Yan Wang. This demand is that King Yan has renovated his palace extensively. It's not so much about repairing. It's better to rebuild. Yanwang Palace has been built with a five-storey reinforced concrete building, and the building is completely converted from new fiberglass. The floor was paved with tiles that only a few families in the Qin State could afford, and the entire palace also had an independent palace system. In order to decorate this building, Yan Guo also used specially customized crystal lamps. You must know that there are no crystal lamps in the palace of King Qin. It can be seen that its decoration is very unusual.

Yan Guo is so wasteful of taxes. And he did not hesitate to use military spending to build palaces for himself. When Shang Wen heard these reports. He even felt that such a government should not be helped. But in fact, Qin could only do this. Because the Yan and Qi countries are still at war. The Qin state needed to consume the military strength of both sides in order to achieve its goal of depleting national strength.

And Qin Guo also knew that Yan Guo really wouldn't last long. It is even said that the collapse of the country is at hand. Especially when the Qi army wiped out the army on the front line, they would immediately counterattack. The threat is real.

"We need to use our air power to deliver sustained air strikes against the approaching Qi army to eliminate the other side. In addition, we need to have a flying machine that can fight at night to curb the night combat behavior of the Qi army. "Wang Jian is simply putting forward opinions from a military point of view.

"Our plan is such that the Celestial Forces are responsible for seizing air supremacy. And strikes are carried out on airships that continue to rise into the air, and our army aviation strikes at ground targets. Wang Jian said as he placed flags marked with the Sky Army and Army Aviation on the big sand table.

Qin's air combat force was still dominated by airplanes and airships, but the airships were comprehensively improved. The first is the adoption of a rigid airship. In other words, the defensiveness has been improved to a certain extent. The second is that the filled gas becomes helium instead of hydrogen, as previously stated. In this way, Qin's airship will be more safe and reliable.

Finally, there is the weapon system of the airship. Since the airship has a large load capacity, this is much stronger than an airplane. Moreover, the state of Qin had previous experience in the use of gunboats in the air. They found that a large-caliber machine gun mounted on an airship could effectively kill and injure ground targets. Especially to load some artillery. Although the caliber of the artillery is not very large. However, it can provide sustained target damage.

While the engineering designers of the Qin State were renovating the airship, they also upgraded the weapon system of the Qin State's airship.

The airship made a transparent cabin in the lower part of the airship using a more rigid fiberglass. This transparent cabin can rotate 360 degrees from side to side. The machine gun can rotate up and down from 180 degrees to 360 degrees. Two large-caliber dot-60 twin air-cooled machine guns were installed in this transparent dome-shaped cabin.

This allows the machine gun compartment to carry out continuous strafing on the ground. Elsewhere, machine guns were also installed on airships. For example, there are two machine guns in the front, rear, and left and right, so that the airship has as many as ten machine guns. The firepower is super fierce.

Not only that, the engineer of the Qin State also modified a three-inch gun at the left door of the airship. The gun can fire both solid and grenades, but mainly grenades, as the guns are mainly aimed at ground targets. And not air targets. The role of solid shells is also not very large, the main thing is that there are no armored targets to strike at this time.

The three-inch gun was equipped with as many as 120 rounds. The machine gun ammunition can reach 20,000 rounds, and not only that, but the airship is also specially humane to install toilet facilities, because the pilot reported that the previous gunboat needed to stay in the air for more than half a day. Some pilots who were in a hurry to urinate had to wear seat belts and pee in the air, what a sight to behold.

Therefore, in order to solve this problem, the airship specially installed a toilet device to provide convenient services for the pilot. This can be regarded as humane. However, the life of a pilot is not so easy, first of all, the airship sometimes has to stay in the air for more than 3,000 steps, the temperature is unbearable in the first place, and some people are not able to breathe.

Therefore, the pilot has to wear a thick flight suit, and at the same time, the problem of eating cannot be solved well. The main thing is that pilots can only eat cold food. There is no hot food to eat, but fortunately their stomachs can still accept such temperatures. However, long-term consumption will cause gastrointestinal problems.

In addition to these, some electrical systems were installed on the airship, which was provided by the addition of a power supply device in the propulsion unit. Electricity is mainly used in two directions. The first is night lighting. They are not used to drive, but to drive searchlights with higher power. This is an airship of the night model. This was the first airship made by the Qin State that was specifically designed for night battles.

In addition to the lighting, there is also the radio. For the first time, airships used radio stations, and for this purpose, the Space Army and Army Aviation set up a special wireless communications section, and ground crews also organized a large number of personnel for radio training. But the first thing the instructor told them was.

"Radio is electricity that doesn't need wires. It's barely possible to talk at close range, but you should send a report, and I would say that the most important thing is that it's because he's wireless. So don't expect too much from him. He's wireless. That's what the instructors tell their trainees.

The pilots of the Qin State were very interested in radio technology, mainly because they solved the problem of shouting or gesturing when they were flying. Although it was told at the beginning that the radio was not very reliable. Indeed, the instructors could not do anything at a distance of a thousand paces during the experiment. The worst part is that sometimes it's hard to even send out the report, they think it's a broken machine, and they don't know what the military is spending taxpayers' money on this.

Except for airships, there are airplanes, but the planes have not changed much. Qin still uses the old Eagle fighters, and in terms of manufacturing, this aircraft is mainly equipped with some larger horsepower engines, and there is not much improvement, such as the use of metal skin or something, they have not done it at all.

However, the military has used this aircraft to carry out several other derivations, such as changing to reconnaissance aircraft, liaison aircraft, and battlefield observation aircraft. At the same time, the Navy and Air Forces also experimented with a seaplane equipped with pontoons. This aircraft is mainly used for the Qin naval aviation to use the aircraft on the water, and they found that if some special supply ships are sent for fuel replenishment, then they can use the surface to take off and land, which can greatly save the use of aircraft airports. Because airports need to be specially built, especially when landing, planes are easy to crash, if pontoons are used, this situation can be greatly improved. The most important thing is that the restrictions of the airfield can be freed, and the combat area can be much wider. This is one of the most important weapons of naval aviation.
