In Zhang Fan's opinion, for himself now, the cumulative distance of about 18,000 kilometers from the same Heavenly City to the estimated Phantom Island is not too far away, even if it is separated by the sea and in the air. Therefore, I also took advantage of the time when I was flying forward, and tried to use some unique flying machines. This rough aircraft was designed by Zhang Fan according to the general shape of a non-vertical tail PCA sixth-generation aircraft or a "five-and-a-half-generation" light fighter in his impression. Because Zhang Fan estimates that this is probably a known pinnacle of human design from stealth to pneumatics, right?

With an unprecedented increase in spiritual power, allowing Zhang Fan to use the spiritual power of the Transformation Realm and even the Heavenly and Human Realm to accurately machine the first-class steel in the air, at least in Zhang Fan's opinion: it is much easier to process the metal shell than the artillery in the Shenwu artillery array. Because for Zhang Fan, whose internal strength cannot reach the realm of heaven and man, but whose spiritual power is very high, the processing of complex but the power demand does not exceed two or three hundred tons of cumulative demand for workpieces is the best trick.

Of course, it is impossible for Zhang Fan, a layman who knows nothing about machinery and even the principles of various aviation engines, to invent and manufacture a variable cycle or even the simplest piston engine out of thin air. The fantasy plane fantasy method solves the problem, so Zhang Fan simply installed a rotating propeller with a bicycle pump structure in the shell of this sixth-generation machine without vertical tail, and directly controlled the inner propeller blades inside the propeller to rotate continuously with internal force.

According to Zhang Fan's rough estimate, his ultimate output power should be 1,000 kilowatts or about 2,000 horsepower, so the size and diameter of the propeller can be about 1.2 meters, and the propeller blades are quite thick.

Of course, there doesn't seem to be too good glass in this world, so Zhang Fan can only make this sixth-generation aircraft shell a convertible with ultralight aircraft specifications, barely able to accommodate two people.

Zhang Fan began to gradually exert his skills to rotate the propeller in the cylinder to push the gas to rotate, the entire 100-kilogram body together with Zhang Fan and Xia Yumeng's total weight of 100 kilograms gained strong power almost in an instant, almost in two seconds or so, the entire body gained a speed of about 100 kilometers, the entire body was almost dry land and rose from the ground, as if it suddenly fell forward, Rao is Xia Yumeng at this time is no longer an ordinary woman, but a top master of the West Sea Continent in the realm of the Inner Gate Eight Grades, without any seat belts and caught off guard, the body can't help but lean against Zhang Fan in the back seat, leaned on Zhang Fan's arms.

"I've just made a force, you don't have a problem, right?" Seeing this, Zhang Fan in the air asked with some concern.

"Rest assured, Lord, the slave is fine!"

"Then you can get ready, I'm going to start testing my extreme abilities, such as those that can be used to escape at the limit in the future. If you feel uncomfortable or can't hold on, don't care about your face, just shake your head... ”

Xia Yumeng didn't know why Zhang Fan let him use this representation, but subconsciously replied: "The slave understands... ”

From the beginning, it only took less than two successes, and in the end, Zhang Fan began to show his ability to be close to the limit. When the propeller power of the World War II Mustang fighter level acted on an ultra-light aircraft with only one-twentieth weight from the members to the fuselage, it almost instantly obtained twenty times the thrust-to-weight ratio of the Mustang and several times the thrust of its own aircraft, and the entire ultralight aircraft was almost like an air-to-air missile after the engine was ignited, and it was on the verge of sound barrier in almost a few seconds under the huge acceleration。 Even when the sound barrier is broken, I only feel a slight explosion and the oncoming wind blowing in front of me is a little stronger.

However, almost within a dozen seconds or so, not only did the entire ultralight aircraft reach three times the speed in the air, which was not too high, but even Xia Yumeng felt that the oncoming wind seemed to be a little difficult to open his eyes head-on, and after a while, the clothes on his entire body began to become hot. Zhang Fan kept trying various maneuvers, and the mobility grew from small to large, and finally reached the level of tens of G, and Xia Yumeng almost tried his whole body to barely fall off this thrilling ultralight aircraft.

However, at this time, Zhang Fan's mental power sensed that the propeller seemed to be a little deformed due to heat at this time. Obviously, it seems that the aircraft was made by himself, and it was made of super-grade steel that is almost impossible to find on earth. However, when he overdrew this ultralight aircraft to the low-altitude power of air-to-air missiles, the propeller blades were still a little unbearable, which made Zhang Fan a little dissatisfied.

Therefore, after thinking about it, Zhang Fan first flew the aircraft to an altitude of about three or four thousand zhang with his own skills, and then swallowed the not too big fuselage into the Qiankun Shield, and began to try to make a new simple aircraft again.

This time, Zhang Fan no longer pursued anything tall, and directly in the tens of seconds in the process of falling, that is, within a few hours in the shield, he used his own internal strength to create a tube that looked like a slipper's shoes, which was nothing special except that it could only accommodate himself. Of course, it also seems to have become a bit stronger because of the simplified form. There are unique exhaust outlets installed at both ends of this sloaf-like flying machine, and Zhang Fan's thinking is also blunt at this time: "In the shield, I have stored at least dozens of tons of secret wine and dozens of tons of charcoal. This charcoal can be smoldered into charcoal at any time using the oxygen inside and outside the Qiankun shield. If I compress these charcoal gases into the Shenwu cannon as quickly as possible, and constantly release them and detonate them at the muzzle of the cannon, they will explode a cloud of carbon dioxide like a projectile. Is this the so-called pulse shock engine or rocket engine in the local method? What kind of engine power can be achieved by this method?"

Thinking of this, Zhang Fan's heart couldn't help but be happy: if this happens, most of his big problems may be solved in the future: that is, if he really encounters a strong enemy that he can't deal with, how can he avoid the other party's attack...

In this way, the muzzle of the Shenwu artillery array was hidden in the Qiankun shield, and it was facing the exit of the Qiankun shield. Under the control of its own internal force, thousands of atmospheres of carbon gas with a density of oil are expelled from the existence of any oxygen, and are constantly released under the control of internal forces. When he first came into contact with the internal gas shield, an explosion occurred almost immediately under the high-speed jet and high temperature brought by high pressure and even high pressure, and under the guidance of Zhang Fan's precise mental power and internal force, the gas continued to be violently ejected at a speed of seven times the speed of sound. Under the thrust of dozens of times the weight of the aircraft
