Since the war, the air has always been the territory of the Imperial Army, but this time, they finally realized that they had made a huge mistake.


    Infected people can build huge dungeons and naturally make their own fighters.


    Although a set of industrial system involves many technical categories to explosion. It is quite difficult to establish a complete industrial system in such a short time.


    However, the relatively simple military volume is not completely impossible. Especially in this universe, the technical difficulty of fighter is actually quite low.


    Even now, the soul guide stamping technology is still a very practical technology, even if the problem of thermal expansion and cold contraction needs to be considered. Most of the time, the accuracy can reach the micron level.


    This greatly reduces the time required to climb the technology tree from scratch.


    In addition, the storage soul guide can also carry propellant for fighters. It can carry a large amount of propulsion medium without increasing the mass. It is absolutely revolutionary for aircraft.


    Moreover, even in tulip, the propulsion without working medium is still in the process of test, and the technology is not mature.


    At present, most rocket engines are not much different from skydiving monkeys in essence, and the fighters of infected people are essentially a huge skydiving monkey that can adjust the flight direction.


    They focus almost all their technology on propulsion and steering. This enables the fighter to be extremely flexible in the air and maintain a very high speed.


    As for how to land


    This problem is not in the designer''s consideration. Infected people can fly. It''s a big deal to jump. Fighters are designed for one-time use. They don''t expect this thing to land smoothly, even without special landing gear.


    Such a large monkey is much less difficult to design and almost no more difficult to produce. You can really do whatever you want without considering landing.


    The speed of the fighter is 30% faster than the fastest fighter in the Empire, although the maximum speed is quite unstable due to the influence of aerodynamic shape and shock wave.


    But this thing is designed to crash. Instability is not a big problem. It can probably fly out of a straight line when running away. Anyway, even if the record explodes in the air, the driver will be fine.


    The low cost makes the number of these things quite huge. More than 500 are dispatched at one time, and each row carries a large number of soul guided bombs.


    Their goal was not air combat, but to bomb the surrounding walls and weaken the strength of the border shrouded in the walls.


    In terms of the range of weapons, infected people are still at a disadvantage. They can equip fighters with machine guns and rockets, but precision precision guided missiles can never be produced on a large scale in such a short time.


    In terms of range, it naturally has disadvantages. Even in the air, it is better at close combat. After all, the soul guide ray has a range of nearly kilometers.


    That thing has no mass and is fast. It shoots almost in a straight line. As long as it is locked, it can''t escape.


    Although the speed of the raid was fast, the Empire also had fighters on standby near the city wall. More than 200 standard fighters took off quickly to intercept the large flying monkeys of the infected people.


    However, the difficulty of this kind of thing is really not small. The big monkeys are running too fast. Missiles can indeed track enemy fighters to a certain extent.


    But only if the missile flies faster than the fighter. Or both sides go head-on.


    The problem is that these large flying monkeys fly too fast, and the drivers have strong physical qualities. I don''t worry about the damage caused by acceleration. As a result, they can accelerate and turn recklessly, and the missile can''t catch up with them at all. Many fighter planes were chasing four or five missiles. Draw a gorgeous track in the air.


    People who didn''t know thought he was followed by a wingman.


    After the imperial fighter, which was at a disadvantage in speed, released missiles and failed to achieve results, it immediately encountered a storm like attack. After the distance was narrowed, the power of soul guided rays was reflected.


    The fast attack can''t be avoided at all. After being aimed, it is basically shot down because of this, although the range is indeed a fatal weakness. But the speed of the large string of sky monkeys is too fast. As long as the fighters they stare at can''t escape the fate of being close to and killed by them.


    At one time, two hundred fighters responsible for blocking suffered heavy losses and retreated in a hurry. Unlike the infected people, they did not worry about the crash and did not even install the landing gear for the fighter.


    Most of the pilots of the imperial army do not have the ability to fly. Being shot down is mostly the end of aircraft destruction and human death. The chance of successful parachute jumping is very slim, so they can''t care about war damage like infected people.


    The fighter planes carried a large number of explosives and threw them in the direction of the city wall. The violent explosion flooded the whole city wall and rocked the border on the city wall.


    Unlike ordinary city level shields, the walls surrounding infected people are too huge. It can''t be shrouded in a whole shield.


    Therefore, the interaction is divided into different blocks. Installed on the corresponding wall. A total of 72 fences were formed, covering all the hundreds of miles around.


    Such a huge range means that they have weaknesses, that is, any shield is independent, if destroyed. It means that the encirclement has opened a gap.


    With the fierce attack in the sky, the ground troops of the infected people also appeared. This time, it was a mighty army of 100 million. Although it was no longer the elite of Douluo level, it had at least the cultivation of soul saint.


    It looks extremely shocking, with 100000 people boundless, but if you carefully distinguish it, you can find it. Only the most peripheral of these people are soldiers. In fact, the middle part of the team is only ordinary infected people who have received simple training.


    They are really strong, but without organization. It''s hard to say how much strength they can play, which can be judged from the relatively thin purple sea of clouds above their heads.


    The purpose of infected people is not to attack the city, but to send out a large number of infected people who lack combat effectiveness.


    These people could be engaged in production before, but after being surrounded, they became a burden. They had to be escorted out of the encirclement. To make the most of them.


    After seeing through this, the commander of Tiandou Empire not only did not breathe a sigh of relief. On the contrary, he looks more and more dignified. If he is killed by these 100000 people, the Empire will win the war. I also lost strategically.
