This is a world of cultivation, and if it's just an ordinary airplane, it's better than a toy. The cultivation world has higher requirements for technology, and it must be brilliant enough and practical enough!

If the plane only flies a few hundred meters, or a few thousand meters, and the flight speed is only two or three hundred kilometers, it can only be reduced to a joke in this cultivation world, and this will affect the image of the Dayang Group.

Although it is inevitable that the development of technology is a little naïve at the beginning, no one likes to watch their own jokes. Especially the current Dayang Group, but pay attention to the image. Therefore, Zhang Hao needs to be extraordinary as soon as he makes a move!

This plane needs to fly at least 70 kilometers above the aura layer, where the air is much thinner and the gravity (gravity) is ten times higher than that of the ground!

But this world is not without merit. The atmosphere in this world is so thick that even at an altitude of 70 kilometers, the air is still thick enough to provide sufficient lift for aircraft.

In short, it took more than three years to create the first aircraft that met the standards under the condition that Zhang Hao was opened, and with the participation of Huang Mingshan and others.

Along the way, Zhang Hao passed by biplanes, triplanes, straight-wings, forward-swept wings, swept wings, wooden, aluminum, and even a variety of planes in the shape of canvas skins, kites, birds, and bats, and finally came to the back of the square, a huge hangar.

In this large, well-designed hangar, Zhang Hao saw the aircraft to be visited today.

Even if Zhang Hao has seen pictures and models, he is still a little amazed when he sees the real machine at this time. I couldn't help but exclaim: "Amazing!"

In a short period of more than three years, the Dayang Group has mobilized countless manpower, material, and financial resources, and the Dayang Group has gone through the stage of aircraft youth in three years under the condition of being built behind closed doors. Directly came up with a full-fledged aircraft that can fly to an altitude of 70 kilometers and has real combat significance!

The current plane, showing a rounded and streamlined shape, is not at all as simple as the aircraft of the other world at the beginning, and there are already some shadows of the aircraft technology in World War II that have begun to mature.

The shape of this aircraft is very similar to Zhang Hao's impression of the German 'Focke-wolf' fighter - this is Germany's legendary ace fighter, but there are still some differences. After all, in just three years, it is still behind closed doors, and there is always something lacking.

The current aircraft is 3.2 meters high, 12.8 meters long and 16.7 meters wide - the wings need to be large for sufficient lift, and the straight single wing, single-engine 14-cylinder star engine and four-bladed propeller are used.

Also, the wings are located above the fuselage, not below.

Zhang Hao looked around slowly, gently stroking the cold, aluminum body, and the excitement in his heart could not be suppressed.

For Zhang Hao, although Zhang Hao was excited, it was difficult to arouse 'pride' when he entered the stage of cultivation, Dayang Group was valued by the ancient family, explored the secrets of this world, and the periodic table.

In particular, the first splendid pearl of industrial technology -- aircraft technology and industry!

The representative of the primary industrial technology, which is also the representative of the first stage of industry, is the cannon of the giant ship, and the representative of the second level of industrial technology is ...... Plane!

The significance of airplanes lies not only in the improvement of industrial technology, but also in the fact that human beings have broken through the inherent living space! Even in this world of cultivation, the significance of airplanes is not trivial.

Airplanes represent the take-off of civilization.

With pride surging in his heart, Zhang Hao's voice was a little high, "Has this plane been tested in the base?"

Lin Yinghao said with some pride: "Teacher, it's flying over." The height of the barrier can reach one kilometer, and the range is more than ten kilometers, and we flew for seven hours yesterday, because it is an internal circle, and the speed is controlled at 280 kilometers, with a total range of about 2,000 kilometers.

If it's outside to let go of the flight, it's going to be farther.

The aircraft is designed for speeds up to 800 km and has a range of 4000 km. This data was measured in a wind tunnel.

It's just that...... Because it has been flown and tested within the barrier, this data may not be accurate. ”

Zhang Hao raised his head, looked at the enchantment in the sky through the hangar door, and smiled faintly: "Airplanes need the sky." Now that you're almost up to the mark, let's go out for an interview! You've been buried in your head for three or four years, and it's time for the outside world to know about you. ”

"Really?!" Lin Yinghao was overjoyed. After all, he is a young man, although he has been lying here for three or four years because of his hobbies, dreams and beliefs, but he yearns for the sky after all.

Not only Lin Yinghao, but also most of the people involved in the research are eager to cheer and cheer from the outside world!

In the past three or four years, they have studied new star engines, solved the fluid dynamics of flight, developed fretting hydraulics, and of course, researched new machine tools for the production of airplanes, and so on.

Behind an airplane is the support of a complete industrial system. Of course, strong financial resources are needed to support it.

The propellers began to circle, and in the roar and whistling of the plane, the plane slowly drove out of the hangar. The person in charge of driving is Lin Yinghao himself.

The enchantment of the sky was microwaved, closed for the first time in four years.

After taxiing out of the hangar, the plane adjusted its direction and began to accelerate in the direction that had been planned.

The roar of the machine was heavy and majestic, and the aircraft, loaded with fuel, with a take-off weight of 5.6 tons, began to accelerate slowly under the traction of the propeller.

The speed became faster and faster, and without the assistance of the formation at all, the two front wheels of the plane gradually left the ground, and the small wheels on the rear tail also left the ground.

The plane, completely suspended in the air!

The roar quickly became distant, and the more powerful sound echoed between the heavens and the earth, faintly revealing the breath of freedom.

One of the god-transforming stage guards beside Zhang Hao couldn't help but be shocked at this time and said, "Unexpectedly...... Completely unaided by formations and spells, is this a bird that flies?"

Zhang Hao didn't speak, just watched quietly.

After the plane flew into the sky, the sound of the engine changed rapidly, and the plane rushed straight into the sky at an elevation angle of almost 7 degrees, and the speed was getting faster and faster.

Zhang Hao pointed to the three masters of the Transformation Stage on the left and right, and said, "Catch up and take a look." Prevent accidents. If anyone comes close, kill them directly!"

The three gods couldn't hold it back for a long time, and at this time, they didn't even have time to sacrifice the flying sword, so they directly controlled the light of the supernatural power and rushed into the sky like lightning.

And in the base, there were also more than a dozen god transformation masters who rushed out.

Zhang Hao stood on the ground, quietly watching the plane become a black dot and gradually disappear above the white clouds, with a bright smile on the corner of his mouth.

A new era is about to begin!

The war being waged now is more like a 'World War I,' but Zhang Hao wants to link World War I and World War II together until a new order is established in the whole world! In this way, casualties can be minimized to the greatest extent.

A new world always needs to be born in the flames of war. Because only the fire of war can burn away the decay of the past and illuminate the future.

War is the curse of human civilization, but it is also unavoidable for human civilization to break out of its cocoon. War does not necessarily bring progress, but every take-off of human civilization must be accompanied by war!

In this era of drastic change, war is inevitable. What Zhang Hao can do is to try to guide a 'war that ends all wars'!

............

The plane roared, and Lin Yinghao screamed excitedly. The aircraft has been researched for more than three years, almost three and a half years, and the construction of this base has been four years.

Four years ago, he was named by Zhang Hao because of his top grades in fluid mechanics, mathematics, physics, and internships. Since then, he has come here, immersed himself in research, and has never left here for half a step, even to visit his relatives.

How much he has endured in the past four years, only he knows. In fact, the first successful test flight of the aircraft was two years ago, but Zhang Hao was still not satisfied.

Until today!

Until today, he finally had the opportunity to fly an aircraft of his own design and rush into the blue sky.

There are no spells, no formations, it is completely the power of industrial technology, this is the power of knowledge.

Unlike the spells and practices that he knew but didn't know why, he remembered every nut and every detail of the engine of this plane.

Why this aircraft can go to the sky and why it can fly at such a speed and altitude has been determined as early as the time of design. In this, there is no metaphysics!

When the plane rushed into the white clouds, Lin Yinghao roared excitedly, and when the plane overtook the white clouds, his pride was already overflowing, but the excitement on his face disappeared and was replaced by solemnity.

This time, the plane will not challenge the white clouds, but the space above the aura layer at an altitude of 70 kilometers, and the harsh environment!

After circling twice, the speed of the plane has exceeded 800 kilometers, and the dial has shown a speed of 832 kilometers per hour and an altitude of 18 kilometers.

However, at this time, the mechanical instrument has a large error, Lin Yinghao probably calculated the altitude and air pressure, etc., roughly calculated, the real speed of the aircraft now, should be about 850 kilometers.

At this time, Lin Yinghao once again pulled the plane up to an elevation angle of 7 degrees and rushed to the air again. This time the goal, depending on the altitude of 70 km!

............

However, it is said that outside the aircraft research base of the Dayang Group, a little far away, that is, outside the one-kilometer cordon, there are many spies.

The Dayang Group did not hide the fact that there was a secret research base here, after all, the trains and cars that come and go here every day cannot be concealed. However, people don't know what is here and what is being studied.

It's just that in the past three years, there has been no movement here, the barrier is open all year round, and the Ocean Group has not been merciless in killing spies, so everyone has gradually relaxed.

It wasn't until today that Zhang Hao suddenly came here in person, which attracted more attention.

Of all the spies lurking here, Cold Wind is probably the longest. And compared to other spies, he still has a little bit of resentment towards the Ocean Group.

Leng Feng, during the first voyage of the Dayang Group, came to visit the Dayang Group with the "Zhiyuan", but in the end, he was rejected when visiting the dock of the Dayang Group, lost face, and since then he has embarked on the road of discrediting the Dayang Group.

However, after sparing no effort to smear the Dayang Group for several years, Leng Feng found a problem: the more he said bad things about the Dayang Group, the more interested everyone was in the Dayang Group.

It's really strange! A strange thought appeared in Leng Feng's heart: Is this person all cheap? Don't listen to good words, but listen to strange things?

After gaining experience, Leng Feng no longer went to smear the Ocean Group head-on, he joined Xi Kunlun, and then with the help of Xi Kunlun, he finally walked into the 'Golden Body Realm'.

However, it is West Kunlun that has now also established its own transformation technology base.

After that, Leng Feng volunteered to lurk here in the Ocean Group and was responsible for investigating the intelligence of the Ocean Group.

Before I knew it, it had been five years, and the cold wind was like the intelligence leader of Xi Kunlun here in this ocean group. Two years ago, Leng Feng set his sights on this research base of the Ocean Group.

This base, which has no name, not even a code name, but has been determined by long-term observation that it is a research base.

For several years in a row, a large amount of materials could only enter and exit, and it is conceivable that extremely confidential research must be going on here.

A year ago, Leng Feng began to personally supervise the place, but after a year of supervision, there was almost no gain, and he was about to give up. The Secrecy of the Ocean Group has made all the spies desperate.

In a positive and fast-growing group, and a group that has its own core and is transforming into a 'holy place', the centripetal force and cohesion of personnel are terrible.

It is incredibly difficult to plant a spy in such a group. Even some spies took the initiative to expose after entering the Dayang Group!

In particular, Dayang Group is a technology-based enterprise, and any important position needs a little technical foundation. Otherwise, it is the guards, etc., and the guards are strictly required, and the slightest deviation will be investigated.

However, the technological environment is relatively closed, and it is impossible for a person's technology to come out of thin air, which greatly hinders the infiltration of spies.

Because of all the above willingness, as of today, the highest-level spy that Leng Feng has planted in the Dayang Group is actually just a chef and a cook of a road construction engineering team.

And if you need a little bit of expertise, it's almost impossible to get started.

Until noon today, a spy in charge of the headquarters and public toilet sanitation of the Dayang Group suddenly sent information that Zhang Hao was going to the south and to the secret base in the south that did not even have a name or a code name.

The cold wind hurried in.

I didn't want Zhang Hao to enter this base less than an hour ago, the enchantment disappeared, and a huge but simple base was presented in front of the cold wind.

Then, a silver-white object flew into the sky like lightning.

The cold wind was stunned.

What the hell is the Dayang Group researching?
