Ninety-ninth Bureau Health Center, Ward 224, this ward used to entertain Gao Shuai and Matsushima Kohachi, and now it has a new guest, Cheng Peng, who can travel around the world at ten times the speed of sound with his body. Pen % fun % Pavilion www.biquge.info

Circumnavigating the Blue Star in six hours with his physical body, although it is not the longest circle around the equator, it is still remarkable, and it also surpasses Cheng Peng's own limits - both speed and mileage.

However, there is also a price to pay for exceeding the limit, that is, he was admitted to the hospital not long after he flew back.

"You won't be able to recover in about a week." Gao Shuai took the diagnosis results handed over to him by Huang Baozhong, and couldn't laugh or cry.

It is a good thing to get the support of a powerful supernatural power owner like Cheng Peng when the country is facing more and more threats from the outside, but he injured himself when he first came, especially under the premise that no one asked him to go around the Blue Star, which made Gao Shuai a little unsure of what to say.

"This is still under the condition that I use the battlefield mode to speed up your recovery, if you rely on your own physique, it is probably impossible for a month or even longer." Gao Shuai took advantage of Huang Baozhong's diagnosis to learn more about Cheng Peng's details, and found that even after the first stage of physical strengthening, the main indicators of this thin young man still lagged behind normal people. Judging from the current situation, he is probably the worst in physical fitness among all the possessors of divine powers, and even Wu Neng can't compare. You must know that Wu Neng's strength is so weak that he can't tell if he can beat the Mao family twins. Of course, Wu Neng himself firmly denied it.

Without the help of the "battlefield", as Gao Shuai said, even if Cheng Peng is given a month, he may not be able to recover as before. From this, we can also see how deep the damage to Cheng Peng is to forcibly break through the limit to ten times the speed of sound.

In fact, Gao Shuai didn't expect Cheng Peng's body to be so weak at the beginning, you must know that Cheng Peng is flying at ten times the speed of sound, not to mention the strong air pressure, not to mention the human being, even ordinary planes may not be able to withstand it, not to mention the huge damage caused by the thermal barrier effect after exceeding three times the speed of sound.

The speed of sound propagation in the air at room temperature is about 340 meters per second, which is 1224 kilometers per hour. If the speed of motion of an object exceeds this limit, then it also exceeds the speed of sound. At this time, that is, when the speed of sound is doubled, the object will catch up with the sound waves emitted by its high-speed motion, which is the sound barrier. When the sound barrier is crossed, the sound waves are overlapped and accumulated, and the pressure difference between different sound waves explodes in an instant, which is a sonic boom. Once this double speed of sound is crossed, the moving object runs ahead of its own sound, and there is no longer a sound barrier.

However, for a moving object in the atmosphere, such as an aircraft, the test has only just begun after exceeding double the speed of sound. One of the most threatening of those demanding tests was the heat barrier. When the aircraft flies at supersonic speed in the atmosphere, it is affected by the strong compression wave in the supersonic gas, that is, the strong friction between the shock wave and the aircraft and between the aircraft and the air, the high temperature generated by these frictions will increase with the increase of the speed of sound, when it exceeds twice the speed of sound, the temperature has exceeded 100 degrees, and when it is three times the speed of sound, it will rise to 350 degrees! Because the high temperature of 350 degrees can already cause strength damage to the material of the general aircraft, such as aluminum alloy, and this damage will further affect the overall structural strength of the aircraft. Therefore, in general, the thermal barrier of triple the speed of sound is taken as a standard, that is, the general thermal barrier refers specifically to the range after the triple speed of sound. In fact, from the beginning of the transatonic speed, the thermal barrier has existed, the difference is only the size and the impact on the aircraft.

This is why ultra-high-speed vehicles such as spacecraft or satellites are very concerned about heat insulation, especially during re-entry.

Cheng Peng didn't just cross the speed of sound, he didn't even cross three times the speed of sound! In fact, when he accelerated to six times the speed of sound, he was facing a high temperature of nearly 1,500 degrees! At this time, ordinary steel can be melted. Not to mention that when he swept over the country and the Pacific Ocean at 10 times the speed of sound, he would face an even more terrifying number.

So at first, Gao Shuai was still puzzled, because at first glance he could see that Cheng Peng's body was not very good, not to mention the strong wind pressure of six times the speed of sound, how did he survive the high temperature of 1500 degrees? Especially when he was sent to the health center after the completion of the global feat, and found that Cheng Peng was even weaker than he imagined, Gao Shuai was even more curious.

Another point is, flying so fast, why is Cheng Peng's clothes intact? This is much stronger than Wu Neng, who can't have clothes if he wants speed, and the prerequisite for that guy to escape quickly is that he must undress......

It's really the overall image that affects the origins.

"My magic power is shock wave oscillation, which uses weak compression wave oscillation to maintain buoyancy in the subsonic state, and when it reaches supersonic speed, it uses the extremely fast jump of strong compression wave to oscillate the surrounding air, forming a strong reaction force to accelerate. So when I'm flying and hovering, I have a 'crackling' sound, which is the constant oscillation of the compressed wave. It is precisely because my flight uses shock waves outside the body surface that it is equivalent to wrapping a protective film on the body surface, and no matter the high temperature or air pressure, it will not affect me. Cheng Peng explained.

"A high-tech roc, to be expected." Gao Shuai nodded, which was very in line with the consistent style of supernatural powers, all kinds of unaware black technology.

In fact, Gao Shuai still understood the basic principle that Cheng Peng said, that is, he could use the oscillation of certain air pressure fluctuations to obtain the reaction force required for flight. As for how this specious truth is reproduced in reality with science and technology, I'm sorry, but the researchers of the Divine Management Committee are still sharing their hands.

How else can it be said that it is black technology?

However, Gao Shuai still has gains, in addition to knowing Cheng Peng's most basic flight principle, he also has a general idea of how to use Cheng Peng's supernatural powers in the future and the problems that need to be paid attention to in future actions. At least because of the constant sound made during the flight, all the tasks that need to conceal his whereabouts are insulated from Cheng Peng.

Cheng Peng's performance made Gao Shuai very satisfied, because of the injury, so this young man was finally able to settle down and speak slowly, Gao Shuai didn't have to worry about what he said wrong, he went on another trip around the world.

In fact, Cheng Peng, who was quiet, was quite modest and friendly, at least when facing his idol Gao Shuai, and even he sincerely apologized for his recklessness, then hesitated for a moment, and asked cautiously: "Brother Gao, can I really recover?" ”

Seeing that Cheng Peng really regretted it, and felt instinctively scared and frightened of being paralyzed in bed again, he was afraid that he would lose the possibility of flying after this injury.

"Trust our judgment." Gao Shuai smiled and comforted, and then couldn't help but sigh: "Our worries about your injury will definitely not be below you, now that Shen Guo has the largest number of supernatural power owners in the world, but the main battle force is lacking, you are our hope." So, recuperate in peace and don't think about it, and soon you will be flying again, I promise. ”

Gao Shuai was telling the truth, whether it was about Cheng Peng's injury or the relative lack of owners of Shen Guo's main battle supernatural powers.

Cheng Peng, who was guaranteed, was obviously relieved, the supernatural power was the only thing he could rely on to get rid of the nightmare of twelve years of paralysis, and it was great that he would not lose it. Then he heard Gao Shuai's sigh again, Cheng Peng suddenly remembered something, first stunned, and then asked: "Brother Gao, have you heard of a supernatural power owner named Chen Ao?" I remember you were still a city. ”
