The principle of a jet engine is simple: the action of force is reciprocal.

If no one controls the nozzle of the high-pressure water pipe, it will only scurry around due to the water pressure, and even push people away when the person holding the nozzle is not strong enough.

Qin Heng needs to do more than just create a high-pressure water pipe. Although he can compress air and then release it to generate powerful power, it takes time to compress air, and it also takes time to capture air elements, which will lead to the use of this method. The kinetic energy obtained is intermittent and not stable enough.

Moreover, pure jet cannot provide the kinetic energy for high-speed flight.

What he needs to do is to use magic energy to stabilize the four working processes of the jet engine according to the principle of the jet engine: intake, compression, combustion, and exhaust.

The most difficult of these is combustion, the 'internal combustion engine' that simulates the engine.

Under normal circumstances, even the temperature of the internal combustion chamber of the engine of the fifth-generation fighter is less than 2000 degrees, while the temperature of a general turbofan engine is 1400-1700 degrees.The flame magic that Qin Heng can create can reach this temperature, and the temperature of the scorching dragon flame can even reach 4000 degrees.

So the difficulty lies not in the temperature, nor in converting heat energy into power, but in the structure of the air element 'engine' made by Qin Heng, which cannot withstand such a high temperature.

From a scientific point of view, it is the development of materials science that restricts the development of engine manufacturing technology.

Because Daisy was next to him, Qin Heng was only compressing the roundness of the air that seemed to be an invisible substance, and did not use magical energy to create flames.

[If you simply use air elements to make a propeller, although it can provide some flying capabilities, but because maintaining the existence of the propeller and controlling its high-speed rotation requires too much magic energy, it is impossible to fly for a long time, and the speed will be very slow .With the same consumption of magical energy to create flames, the resulting high temperature can convert much more kinetic energy, and both the flying speed and the flying distance will increase a lot. 】

[However, I have already compressed the air to the extreme that I can compress, and I still cannot withstand the power generated when the high temperature of the flame is converted into kinetic energy, let alone the higher temperature, which can generate more powerful kinetic energy. 】

Qin Heng looked at the stable 'air element jet engine' floating in the air on the hand stretched out of the car window, and began to think about how to solve this problem.

[Materials science is one of the main disciplines that restrict the development of science and technology. Even the controllable nuclear fusion technology, in the final analysis, is due to the constraints of materials science, and it is impossible to produce materials that can withstand the high temperature of controllable nuclear fusion.To put it simply, scientists want to pack the sun into a box, and then convert the heat energy generated by the sun into electrical energy and kinetic energy, but scientists don’t know how to make the box, and the existing materials can only resist it for a few seconds. clock time. 】

[And my current problem is that I can't hold it for a second, otherwise, I can fly in a second. 】

The combination of science and magic is much more difficult than Qin Heng imagined.

[How can the air element withstand the high temperature of the flame? 】

After loosening the already formed air motor in his hand, Qin Heng felt a strange touch with his hand stretched out of the window.

The continuous wind, shaped by the shape of the palm, has a somewhat rounded feel.

Qin Heng suddenly understood the question that Daisy asked him just now. Under different vehicle speeds, the tactile sensation formed by the air based on the shape of the palm is also different. The specific difference lies in the size.

Glancing at Daisy who was driving, Qin Heng was stunned for a moment.

【continuous? 】

Looking at his palm facing the wind outside the car window, and the continuous tactile sensation in his palm, Qin Heng's eyes brightened a little.

[Air elements can't withstand the high temperature and kinetic energy of flames, but a cloud mage like Istron can defeat a pyromancer, because Istron can continuously create an air elemental barrier to block the flames of a pyromancer harm. 】

[A drop of water cannot extinguish a fire, but what if it is continuous rain?The engine made of compressed air elements really can't withstand the high temperature of the flame, but when the air elements are destroyed by the flames, what if I continue to replenish the compressed air elements? 】

[As long as the flame can be controlled within a certain range, and then the kinetic energy generated by it can be continuously output, the internal pressure can be relieved and the air element barrier can be strengthened at the same time, isn't it equivalent to obtaining a stable engine? 】

Feeling the enhanced touch in his hands, Qin Heng looked at Daisy who was speeding up the car secretly.

"Find a place to park."

Daisy froze for a moment, looked at the wilderness around her, coughed dryly and said, "Why don't we go to the town and find a place to live... it will be more convenient to take a shower."

Qin Heng frowned: "I said, stop."

The off-road vehicle stopped on the side of the road, and Daisy took a deep breath and looked forward to it.

The co-pilot's door was opened, Qin Heng got out of the car and ran towards the wilderness, and disappeared in the woods not far away.

Daisy was dumbfounded: "He went into the woods? Should I follow?"

Chapter 88 Respective Audience Gathering

魔法能量（400/450）……（300/450）……（100/450）……（50/450）。

Killing the Gods only used 400 points of magic energy. The energy value spent to learn to fly, or to create a 'flying' magic spell, has exceeded 3000 points in these days.

Qin Heng got out of the small woods with a somewhat disheveled face, and saw Daisy who finally walked to the edge of the woods, and it was Daisy who hesitated and had a ruddy face.

"What are you doing here?"

Qin Heng, who failed again, has found the correct method, but still can't see the time point of success, so he is not in a good mood.

Daisy looked at Qin Heng's disheveled face in astonishment, coughed dryly and said, "I said first go to the town to find a place to live, and it will be easier to take a shower. Look at you now..."

"Ha ha……"

Qin Heng sneered twice, and walked towards the location of the off-road vehicle on his own.

It's not that he doesn't understand Daisy's meaning. It's not that he doesn't understand Daisy. It's a problem for Daisy not to be tempted by the long-distance journey, and the exciting thing of hunting and killing vampires. .

But to treat a tool person, you must have an attitude towards a tool person. Facing Daisy, who has always wanted to disclose the existence of vampires, Qin Heng must protect himself. up.

Daisy was a little embarrassed, but followed quickly.

"Did you discover the vampire, did you have a fight with the vampire in the grove just now? By the way, is it a male vampire or a female vampire, how many are there?"

Just as he was about to scold Daisy for shutting up, Qin Heng suddenly thought of Daisy's professional skills, so he calmed down and asked, "Can you build a mathematical model? Or something called a calculation model."

Daisy asked as she walked, "What do you mean? Just tell me what you are."

[I'm your father. 】

Qin Heng thought about how to answer this question.

The matter of knowing magic needs to be kept secret, especially for Daisy, not because he doesn't want Daisy to know that he knows magic, but because he doesn't want those vampires to know through Daisy that he knows magic.

Pretending to be a pig and eating a tiger is very useful for hunting vampires. So far, the [-] vampires he has killed are all done by using physical fitness, combat skills, and the Heartbreaker Sword. He has never used magic once.

There were also two or three "living victims" similar to Hunter's. In addition to letting these living victims find more vampires, they also wanted those vampires to spread his fighting style and combat power to other vampires.

If the vampire knows about his magic through Daisy, it will affect his hunting.

"Starting today, you teach me computers."

Qin Heng, a former junior college student majoring in computer science, decided to regain his professional knowledge. He was full of motivation after not studying well in the past, and his improved memory and analysis ability also gave him the confidence to become a computer expert in a short period of time.

Learning the tools of a tool man is much better in many cases than carrying a cumbersome tool man.

"Huh? Oh, good."

Daisy agreed.

The two returned to the place where the off-road vehicle was, and drove again to the destination town. Qin Heng combined the information Daisy found and his own talent for smell, and quickly found the four vampires in this town.
