Having already had experience in purifying and separating Adamantine Stones, I certainly became much more proficient in the second purification and separation, but it took two days to once again extract materials equivalent to four standard Adamantite Stones.

The structure of the turbojet is actually very simple. At least for Li Xiao, there is no difficulty in disassembling it. In just half an hour, the four turbojet on the aircraft were quickly disassembled into a pile of parts.

As for why these four should be strengthened first, of course it is because the quality of these four turbojets has been completely verified, and there should be no problems after strengthening.

Of course, these parts have been used, so they also deliberately carried out comprehensive cleaning and maintenance on these parts. After removing all oil stains and stains on the surface, the parts were immersed in fine gold solution.

The parts were constantly swaying in the fine gold solution. After more than ten minutes, the parts began to turn pale gold, and then they were taken out and thrown into the flames for burning. The verification also consolidated the coating...

The coating this time is still perfect. The parts were burned in the fire for more than half an hour. After being taken out, the surface temperature of the parts was only a few dozen degrees, and the heat was almost completely reflected by the fine gold coating.

After reinstalling the parts, I took out two liters of fuel, installed the turbojet on a temporary wooden frame, and hung a tension scale... After everything was ready, I started the engine directly.

…

The noise still seems a bit harsh and has not reduced as expected. Even under the same 10% throttle, the noise may increase.

Of course, because the oil circuit has not changed, the fuel consumption will not be reduced at the same throttle. However, at the same throttle, the thrust of the turbojet increases beyond the phenomenon, even increasing several times.

It is said that the thrust of a turbojet engine comes from the air expansion effect caused in the combustion chamber, and every time the temperature in the combustion chamber increases by 100 degrees Celsius, the thrust will increase by about 20%.

Limited by material limitations, components can easily be damaged if the temperature in the combustion chamber is too high. Therefore, in general turbojet engines, the combustion chamber temperature is basically controlled within 1,700 degrees Celsius.

However, the fine gold plating is a perfect heat-resistant material. The most amazing thing is that it reflects almost all thermal radiation, causing the temperature in the combustion chamber to soar sharply.

The sharp surge in temperature caused the air expansion to increase significantly, and the thrust also increased significantly. When the throttle was increased to about 15%, the thrust of the small turbojet increased to 25 kilograms. When the throttle was pulled down to about 25%, the thrust directly exceeded 40 kilograms.

…

When the throttle continued to increase to 40%, the hot air flow ejected from the tail actually lit up a series of Mach rings. When they saw this thing, not only a large group of monkeys watching in the distance were confused, but also Li Xiao

Also a little confused.

This is a magical phenomenon that occurs when the airflow exceeds the speed of sound. It is a sign of a supersonic cruise fighter. In other words, if this thing is installed on a suitable micro-aircraft, it can make the aircraft easily reach supersonic speeds.

cruise.

Of course, flying skateboards are not aerodynamic and will certainly not be able to fly at supersonic speeds, but what is certain is that driving this kind of aircraft will increase the flight speed greatly.

The throttle continued to be increased to 55%, and the thrust of the turbojet exceeded the detectable range of the 100-kilogram pull scale.

Originally, the maximum thrust of this small turbojet was only 40 kilograms, but now it has exceeded 100 kilograms at 55% of the throttle, and it has successfully reached 40 kilograms of pull with only 25% of the throttle.

The thrust increase is more than four times. This increase is indeed a bit unexpected. The substantial increase in thrust certainly means that the range that can be provided by a pack of fuel is increased by more than four times.

Moreover, the maximum flight speed will be greatly improved. As for how much the maximum speed will be improved, we will not know until it is reassembled and tested for flight.

The improvement of aircraft is not only about the improvement of flight speed and flight distance, but also a qualitative leap in stability, making it almost impossible to malfunction and requiring no maintenance for life.

The versatility of the fuel will also be greatly improved, and most of the fuel can be used. It is just a matter of whether the thrust is larger or smaller. All in all, the four standard adamantine stones this time are indeed worth the money.

…

After thinking about it, I took out some high-purity alcohol and tried it. It can indeed be used normally, but the thrust is reduced by about 50% for aviation kerosene. However, the current turbojet efficiency is high enough, so alcohol can be used as fuel.

Then I tried mixing alcohol with a low ignition point and rapeseed oil with a high ignition point, and added a fuel pack. It still started up and ran smoothly. Even the thermal efficiency was quite high, which was slightly worse than aviation kerosene.

In the end, it died tragically when very high-purity industrial alcohol was mixed with water, and the alcohol content was reduced to about 60 degrees, a level that many high-strength liquors can reach, but it was still usable.

Even the thrust did not decrease as expected, but increased slightly. It seems that the extremely high heat reflection of the fine gold coating successfully maintained the extremely high temperature of the combustion chamber, and the water molecules in the alcohol encountered extremely high temperatures.

The volume expanded more violently than air.

It's just that the tail no longer sprays flames and has no Mach ring, but sprays out a large amount of white mist. The mist instantly covered a large area, scaring the monkeys watching the show in the distance and fled to another place.

Far away.

It seemed that Bai Yuan was brave enough to be an expert in martial arts, so he came close to Li Xiao with a look of envy on his face.

"I didn't expect that Brother Li could just create a magical weapon and be able to swallow clouds and mist. I guess it's not that far away from the real soaring clouds and mist, right?"

"Using magic weapons to fly is just a small way, and you can't get on the stage. You should practice hard and use your own true energy to control the power of heaven and earth to control the clouds and mists. It will be much more powerful."

"It is not easy to break through the heavens and humans and call upon the power of heaven and earth at will. Many monks cannot do this in their entire lives because of the convenience of magic weapons."

"Old Bai, this thing is very precise. I can't make it out of thin air, so don't worry about it."

"I know, I know, something that can soar into the clouds and mist is certainly very advanced. I'm not worried about it. I just want to understand the principles behind it."

"It's not difficult to explain the principle. It's nothing more than burning something and letting the air expand to generate thrust."

"No need to borrow the spiritual power of heaven and earth?"

"Yes."

"Does this mean that the Forbidden Air Formation is ineffective against your magic weapon?"

"It would be ineffective if it were just to ban the borrowing of spiritual power, but the weird energy field like that above the sinkhole, which can directly interfere with the airflow, will definitely stop this aircraft."

"That's awesome...can't you really get one for me?"

"This thing requires extremely high processing precision. Without a huge industrial base, in fact, even if you have this thing, you can't use it with your ability."

"You are looking down on me, my reaction speed is faster than yours."

"It's not just a control issue, but involves fuel extraction and use, equipment oil system, circuit control system maintenance, etc. If you want to use this thing, you have to learn basic knowledge for a long time... If you have this time, you might as well focus on it

Breaking through your realm of heaven and humanity is real."

"How can heavenly beings be so simple? My understanding is not very high. I have been cultivating for more than a thousand years and I have not yet become a heavenly being. Maybe I will never even think about going to heaven in this life."

"... Your Qi is extremely strong, almost to the point of being endless. I thought of a special method that might allow you to fly in the air." Li Xiao suddenly remembered the tornado he had obtained in the game world.

A spell book. In theory, this spell can not only blow away enemies, but also blow yourself into the sky.

"What? Can you teach it to me and at what cost?"

"Well, your meridians are slightly different from the human meridians. I can't guarantee whether that method is feasible."

"Brother Li, you are trying to kill me. Please tell me what conditions you need to teach me."

"We are all friends, so what are the conditions for communicating with each other? Sit down and I will point out to you the path of the movement of your true energy. However, your meridians and meridians are slightly different, so you have to try to correct them yourself."

"I understand, I understand, don't worry, I have been with Mr. Chisong for hundreds of years, so of course I understand this simple truth." He said and quickly sat down.

Seeing the other party's answer, Li Xiao no longer struggled with the question of whether that method was feasible. He directly used his luck and fingertips to send a trace of biological current directly into the white ape's body, and began to lead the white ape's vast sea of ​​true energy to circulate in the meridians.

The White Ape, who has lived for thousands of years, is indeed experienced. The only thing that seems to be lacking is that someone has given him some guidance. Li Xiao pointed out the path of Qi movement for controlling the tornado technique. Although it is only suitable for humans, the White Ape easily calibrated it.

some deviations.

Even the tornado technique that he mastered on the spot, with the movement of the true energy, an energy field spread to the surroundings, and the wind surged in an instant. Seeing this situation, Li Xiao, who had finished giving instructions, also hurriedly fled away.

The white ape sitting on the ground was swept up into the sky by the increasingly violent tornado. I don't know if he was too happy, too nervous for the first time, or too complacent.

He fell down just after reaching an altitude of six to seven hundred meters.

A deep pit was created on the ground, and the white ape jumped out of the pit unscathed. Although he was a little embarrassed, he looked up to the sky and roared excitedly.
