"Woo" A Qin fighter roared past. The twin-engine "Eagle" fighter flew swiftly past one of Qi's newest hot-air airships.

The "Tutu Tutu" machine gun fired three bursts. The machine gunners in the back aimed at the hot airship of the Qi Air Force and fired incendiary bullets.

It's a pity. Three bullets did not stop the hot airship. Qi immediately conducted research after accidentally obtaining an airplane. The main result was that they mastered the secrets of the propeller. I learned about the use of air flow as a propulsion force. But their aerial vehicle is still a spherical hot air balloon.

The subsequent capture of the airship crew greatly improved Qi Guo's flight skills. That is, they also began to pay attention to the external shape of the airship. That is to make it a cigar type. Cross wings are also installed for easy manoeuvring.

Although the crew presented information about the use of hydrogen as a filling gas for airships by the State of Qin. But the production method of this hydrogen is not yet known to the Qi people. The crew concealed the fact of electrolysis. The people of Qi don't know what electricity is. They only know that it was mentioned in the newspapers.

But none of that matters. The people of Qi have made great progress in airships. It's not just the form. There are also propulsion units. Their airbags are starting to have brackets. The main frame is made of wood. The rest of the supports are bamboo. This can drastically reduce the payload of the airship.

On the choice of fuel for the airship. The Qi people chose kerosene, which was easier to burn. However, air is blown in by air in the air to accelerate its combustion in order to quickly provide enough hot air to rise into the air. In this way, the Qi country has a hot airship with a long combat distance.

The appearance of this airship brought great trouble to the Qin Heavenly Army. Qin's air "gunboats" were all grounded and returned to China. Only the planes that remain can fight. But the front line consisted of only two squadrons of fighter formations. There is only one main airport. There are two temporary airports. Fortunately, during this period, the aircraft did not have great requirements for the landing situation at the airport. However, the Qi Air Force adopted a multi-faceted attack.

I don't know how Qi did it. The number of their airships increased a lot at once. If the Qin army sent reconnaissance planes to some county towns in Qi to take pictures, they would find out how these airships came from.

Qi in order to mass-produce this airship. The government organized nearby women to participate in the sealing of airship airbags. In order to speed up the manufacture of airbags. For the first time, the state of Qi adopted the division of labor contracting system. That is, a group of several women specializes in processing a certain piece of the airbag. In this way, the airbags are processed separately, which greatly speeds up the manufacture of airbags. Of course, there are certain standards for this. This standard allows for a certain margin of error. However, it can be processed generally. To encourage women to process quickly. Qi paid some of the women's wages.

And a few women mostly appear in the form of workshops. Most of their work is done by a representative woman. Then divide the work to do it. This creates a relationship of employment and employment. Although it is composed of several families jointly. And most of them are small workshops. But this is, after all, the germ of capitalism, which was born under the conditions of war. Some of the enterprise management methods of Qin Shangwen also indirectly affected the Qi State.

Except for women. There are also men in the Qi country. Especially carpenters. The construction of the frame is not a simple job. In order to dramatically increase the production speed of airships. Qi also began to implement workshop-type processing frames. So. There is a great opportunity for the development of the handicraft workshop. In particular, the handicraft industry, represented by carpentry, has developed rapidly.

The Qi Air Force has also made some adjustments. That is to keep some capable flying teams. Pay attention to the importance of talents. The training of pilots in the Qin State taught the Qi Air Force a lot. For example, flight hours are calculated. Training courses for some technical movements have also been developed. In order to speed up the combat formation of the Air Force. They established the Qi Air Force Flight School. This is Qi Guo's own flight school. The future pilots of the Qi Air Force all went to the battlefield from here.

In terms of weapons innovation. Qi still has not mastered the technology of trigger fuze. The state of Qin sealed it tightly. Although the state of Qin has reached the point of a double-base charge. But they are still afraid that their opponents will get the technology they know before. In particular, Huomao has a technical blockade of it. As a result, Qi has a lot of resistance in terms of weapon innovation. However, the craftsmen of the Qi State invented the flintlock fuze bomb based on the principle of the flintlock pistol.

The bomb uses a well-sealed wooden barrel or clay pot. Then adjust it according to the position of the center of gravity. This adjustment is positioned so that you can throw your head down when you are thrown from a high altitude. This means that the front charge is very large. A bamboo pole was used as an ignition fuse in the charge position.

An iron pipe is inserted into the front of the ignition fuse. Place an iron sand ring where the bamboo pole is inserted into the gunpowder. The gunpowder charge part is also specially processed. That is, from sparse to tightly fitted. This allows for a certain amount of space to retain oxygen to ignite the ignition of the ignition gunpowder. This is the early aerial bomb of the Qi Air Force.

The Qin Heavenly Army could not control air supremacy on the entire front. They have no trouble blasting such airships, though. But it couldn't stop the many airship air raids.

With hot airships, the guerrillas secretly provided more accurate battlefield information. As well as the use of flintlock aerial bombs. In particular, the pottery shards blown up by clay pots and aerial bombs are staggering. Equivalent to a grenade attack. The Qi Air Force, which had successfully bombed frequently, began to gradually occupy the initiative in the air. However, the pilots of the Qin Heavenly Army complained a lot. They are flying more and more. There is less and less time to rest. A lot of pilots are in a state of exhaustion. However, the positions of the Yan army were frequently attacked. And the Qin army could only dispatch planes to patrol in vain.

They can only try their luck to catch the opponent's hot airship and attack. But sometimes it's hard to shoot down an airship even if you run out of bullets. The reason for this is the high penetration of their bullets. But that's even a hundred bullets for a hot airship. At most, that is, a hundred small holes. The airship can still rely on a certain amount of hot air to provide safe lift. For a while, the Qin State pilot hurriedly threw away the toolbox on the plane. Some flying shooters were even more angry, and then threw a bullet at the opponent. The reason is that the airship is still floating in the sky after so many shots.

Not only the Qin army was discouraged. Even Yan Jun was annoyed when he looked at it. This big fat guy is too hard to fight.

"Tutu Tu" was another three-shot machine gun fire. Three rounds accurately concentrate the huge airship airbags. This time, the airship's airbag hit and began to burn. Saw the airship on fire. The machine gunner seized the opportunity to pull the trigger.

"Tutu Tutu" is another series of continuous shots. The bullet hit it and caught fire. The airship soon burst into flames.
