A crying child has milk.

Chu Fei grabbed the Neng Jing that Wu Yong gave him, and leisurely returned to his dormitory.

Speaking of which, Chu Fei's dormitory is still next to Sun Xiangqing's and has not been moved.

On the one hand, due to his busy schedule recently, except for fighting, Chu Fei spends most of his time "studying and practicing" in the research laboratory of the Shuguang team, so there is no need to relocate at all;
On the other hand, there have been many wars recently, and Dawn Academy has no time to solve such a small trouble.

Things have been delayed like this, but it's just a small problem.

When Chu Fei returned to the dormitory, he also met many old acquaintances.

Such as Zhang Xuan, Li Honggang, Lu Hong and other former classmates or acquaintances.However, most of those who stay here are not very high.

Chu Fei took a look, the one with the highest cultivation might be Zhang Xuan, but it felt like 7.9!
Looking at the rest of the people, Chu Fei actually had a strange feeling——unknowingly, he had soared to an unimaginable height.

Zhang Xuan is also a young genius, and now he is "that is" a half-awakened person.

After such a thought flashed through his mind, Chu Fei still greeted everyone, chatted casually, and even pointed out a few people's cultivation.

By the way, I learned that Sun Xiangqing and other old students have entered the team to fight, and many of them died.

Only Zhang Xuan and others who are under the age of 15 and break through the second limit of 7.8 have the right not to go to the battlefield.

Now Zhang Xuan lives next door to Chu Fei, not Sun Xiangqing.

After a short exchange, Chu Fei returned to his dormitory. On the one hand, he closed his eyes and rested his mind, on the other hand, he relaxed and cleared his mind, sorting out the things he needed.

Every major event requires quiet thinking.

Chu Fei even took out a pen and paper and wrote down what he needed.A good memory is not as good as a bad pen, especially when you think too much about things.

First of all, you need a sword and enough swords.Swords are consumables.With Chu Fei's current fighting intensity, it's not a big deal to lose three or five in one battle.

Secondly, enough gun bullets, electromagnetic sniper rifles also need battery packs.

Again, grenades are needed, especially flashbangs and the like.

Finally, medicine, food, etc., normal drones (not tactical drones with only two left).Medicines, in particular, can be used as currency.

After the calculation was completed, Chu Fei glanced at the storage space again, checking for omissions and making up for vacancies.

The storage space has now been opened up to 10 cubic meters, and there is still [-] cubic meters left, which has never had a chance to be filled.

After counting, Chu Fei took another look at the "brain and training device" placed in the corner of the storage space. It was Zhang Zhaoyang's brain.

After checking the data and the condition of the energy crystals, I added some nutrient solution, so I stopped paying attention.

Neng Jing was brought by Zhang Zhaoyang, and based on the current consumption rate, it can last for more than a year.

Even up to now, Chu Fei has not thought of how to arrange Zhang Zhaoyang, nor has he had the time.

In fact, even if he wanted to release Zhang Zhaoyang, he had to leave Feihu City and go to a place where everyone didn't know him, so that even if the storage space was exposed, it wouldn't matter.

"Wait a little longer, the animal horde is just over halfway now, and the horde of living corpses is also beginning to appear."

Consciousness left the space, Chu Fei went straight to the warehouse, replenished the supplies, and finally rose into the air.

It flew out of the range of Feihu City in one breath, and flew into the mountains.At this time, the mountains are relatively quiet, and those stronger beasts are walking around dead.

And Chu Fei found a relatively good place here, and began... to test the limits of flying!
It is said that knowing yourself and knowing your enemy will win every battle. At this time, Chu Fei has no idea what "the other" is, so he can only "know yourself".

If you want to win, you must know yourself and the enemy; if you want to live, you must at least "know yourself".

Flying ability is one of Chu Fei's most powerful "supernatural abilities" now, but after learning "negative pressure flight" from the space of Black Iron City, he has not studied it carefully.

When the lore King Kong giant ape was killed, the key turning point was to use negative pressure flight to complete it, so that the knife could be stabbed into the spinal cord before King Kong giant ape could react.

Suspended in the air, taking a deep breath, Chu Fei started a new test.

First test the basic data:
It takes energy to manifest and retract the wings, and it takes a little time.

Energy, from the previous energy of 20~50 calories, has been "raised" to 24~60 calories—the upper limit has been raised, because Chu Fei's body has become stronger and his wings have also been strengthened.

If it is "fully expanded", the minimum is 24 cards, and the maximum is 60 cards. In fact, it can be larger.The faster it unfolds, the greater the consumption.

The time to unfold and retract the wings has been shortened from 5 seconds to 3 seconds; this is the real improvement.

But 3 seconds still made Chu Fei dissatisfied.Because Chu Fei knew that the deployment speed of Liu Tingyun, Second Senior Brother and others was 0.2 seconds!
3 seconds and 0.2 seconds are the distance between life and death in battle.

But this can't be helped, it takes a long time of practice.After all, Chu Fei had too little time to learn how to fly.

Humans are not born to fly, let alone learn to spread their wings and so on.

Even if it is compressed to three seconds now, it is the result of Chu Fei's extensive practice and (thinking) training.

Secondly, the minimum energy consumption of the test flight was reduced from 100 calories per hour to 60 calories!
This improvement is relatively large, because after the flying ability is proficient enough, coupled with the more proficient knowledge, the aerodynamic efficiency is improved, and after mastering the negative pressure flight method, the efficiency is even higher.

The highest energy consumption of the flight, which is also the maximum flight speed, is increased from 0.3 calories/second (about 1100 calories/hour) to 0.38 calories/second (about 1370 calories/hour);
Correspondingly, the maximum flight speed is increased from 380 km/h to 440 km/h.

At this time, the noise has been reduced from 120 decibels to 116 decibels—this is also an improvement after the flight capability has been optimized.

The energy consumption increased by 26.7%, but the speed only increased by 15.8%. This is because as the speed increases, the resistance is greater and the body burden is greater.

This is because Chu Fei's energy utilization rate has increased a lot.Otherwise, according to the square relationship between kinetic energy (energy) and speed, the lifting effect will be even worse.

The data on the lowest hover is:

The past data is: 15 cm height, energy consumption per second is about 0.18 cal (about 650 cal/hour), there is noise but small, when raised to 40 cm height, the noise basically disappears.

[Old data: at a height of half a meter, the energy consumption per second is about 0.2 calories (about 700 calories/hour), and there is noise; when raised to a height of 1 meter, the noise basically disappears (within 30 decibels)]

Finally, test the overall flight ability:

① Maximum flight speed: 440 km/h, energy consumption 0.38 cal/s (about 1370 cal/h), noise 116 decibels;

[Old data: 380 km/h, energy consumption 0.3 cal/s (about 1100 cal/h), noise 120 decibels—comparable to a fighter jet]

②Maximum flight speed in quiet state (30 decibels): 70 km/h, energy consumption 0.05 cal/s (about 180 cal/h)

[Old data: 60 km/h, energy consumption 0.037 cal/s (about 120 cal/h)]

③ "Maximum" gliding speed (dive): 86 km/h, noise 60 decibels, energy consumption 0.041 cal/s (about 148 cal/h)

[Old data: 84 km/h, noise 60 decibels, energy consumption 0.042 cal/s (about 150 cal/h)]

This data has not changed much, only a slight optimization; because the dive speed is limited by the environment, air resistance, and its own factors are relatively small.

④ "Minimum" gliding speed (the wings do not vibrate, and the wings vibrate can hover): 15 km/h, the noise is less than 20 decibels, and the energy consumption is 0.042 cal/s (about 150 cal/h)

[Old data: 17 km/h, noise less than 20 decibels, energy consumption 0.048 cal/s (about 170 cal/h)]

This change is more obvious.When gliding at the lowest level, the air resistance is very small, mainly due to the adjustment of its own flight attitude, which requires a lot of calculations and a solid aerodynamic foundation.

The lower the minimum gliding speed, the better it is, and it can go deep behind enemy lines like a ghost.

⑤The best combat speed range is 60~120 km/h, which is fast enough in this range and can make almost right-angle turns.

[Old data: 60~110 km/h]

⑥Best long-distance flight speed: 200 km/stratosphere, energy consumption 0.08 cal/s (about 290 cal/h)

[Old data: 180 km/stratosphere]

Long-distance flight requires a comprehensive consideration of the balance of all aspects.Energy consumption, physical fitness, time, physical recovery, crisis response speed, etc.

⑦Horizontal flight acceleration time of 4.4 kilometers: 6.32 seconds, about [-]m/s
[Old data: 4.6 seconds, about 6.04m/s (Chapter 243 data error)]

⑧Maximum flight altitude: It used to be 15 kilometers, but now it is directly raised to a crazy height of 20 kilometers by using the negative pressure flight method!
It can reach this height because the technical parameters of "negative pressure flight" are no longer completely in the category of biology, but have added part of the category of science and technology.

After that, some piecemeal tests, such as deceleration, etc. were carried out.

After the test was completed, Chu Fei hovered above the forest, thoughtful:
"The overall improvement is not great, but it's not too small. It's not a reborn state, but it's not bad.

If the flying ability is improved a little, the actual combat power can be increased by three to four points!

In fact, just because of the change in flight ability, combat effectiveness and survivability, it has increased by at least [-]%!
Flying is really against the sky, especially for humans.

The so-called added wings to a tiger must be talking about this truth. "

After completing the "self-inspection and self-assessment" for an hour, Chu Fei continued to fly north.

The Black Iron City is in the northeast direction, and Chu Fei plans to fly to the north—either due north, or as far as possible out of the radiation range of the Black Iron City.

At this moment, Chu Fei is flying at an altitude of 8 to 12 kilometers, maintaining a flying speed of 200 kilometers per hour.Fine-tuning will be made according to the actual situation during the specific flight.

The average height of the stratosphere is 10-50 kilometers, but the actual situation always fluctuates.The lowest altitude can reach 7 kilometers, and the highest can reach 13 kilometers.

If you want to fly the most easily, not to mention adjusting the flight attitude all the time, but frequent adjustments are still necessary.

The lower the altitude, the greater the buoyancy, but also the greater resistance and disturbance;
The higher the altitude, the less buoyant, but also less drag and less turbulence.

Because the air is dynamic, Chu Fei would occasionally take advantage of the wind to get lazy.

During the flight, Chu Fei continued to summarize experience, collect data, and conduct thinking training.Even gradually integrated into science and technology, intensive training.

In this mode, Chu Fei's flying ability continues to improve.After flying only sixty or seventy kilometers, the negative pressure flight method was completely integrated into the normal flight mode.

In other words, from now on, flying under negative pressure is no longer a "magic", but an "instinct"!
The gap between magic and instinct is actually the gap between "external tools" and "the body itself (noumenon)".

No matter how proficient you are with chopsticks, you still have to find chopsticks before eating—prepare a spell;
But if it's instinct, you can use it without even thinking about it-you don't need to look for your hands if you eat with your hands.

"Perhaps the so-called practice makes perfect, which is to strengthen acquired skill training into innate instinct—at least it is infinitely close."

While thinking, Chu Fei's flying speed increased a little.After integrating the ability to fly under negative pressure, the flight speed reached 210 kilometers per hour when the rest of the conditions remained unchanged!
"I don't know if this counts as an iteration of the driver program?" Feeling the joy of progress, Chu Fei's thinking began to run wild, and at the same time, he was multitasking and flying forward.

Compared with riding a motorcycle last time, this time Chu Fei flew over.Looking down at the rolling mountains from a high altitude is refreshing.

This time, without the pressure of the war and carrying few items, Chu Fei easily soared in the sky above 10 kilometers, overlooking the vast land.

At this time, it is already raining, and the pines have not completely receded from the black and green winter, but the earth is already pregnant with vitality, and the bright yellow colors adorn the mountains and fields, extending to the horizon.

Looking at this magnificent scenery, who would have thought that this is the end of the world!The beast tide broke out once every ten years, and the little civilization power that human beings had just recovered was destroyed.

With a long sigh, Chu Fei began to pay attention to the terrain and other strategic information.

The overall direction of the mountains at present is the direction from northwest to southeast, with the northwest high and the southeast low.

It is estimated that Hong Qingxin, Vajra Giant Ape, etc. went north from the southeast and entered the range of the Black Iron City.

Continue to fly, continue to observe, and want to calculate the road through the mountain through the terrain trend-what if there is a large-scale march in the future?
In fact, the communication between Flying Tiger City and Black Iron City is not completely cut off, there are exchanges every year, although not many.At the same time, they also send people who can fly and even drones to explore the terrain, and they are preparing to open up business routes.

The flying speed was very fast, even if Chu Fei was slow, he flew over the mountains and mountains in half an hour, and then saw a "familiar strange beast" - an albatross, an albatross with a broken claw.

But now this albatross has added a "mechanical claw"—or a breeding suit!
Seeing this Chu Fei felt like scolding her mother - Hong Qingxin, you are going too far!
Humans don't even have enough reproductive equipment, yet you use it for animals.Oh, you're a beast now too - this isn't a curse, it's a straight statement.

But what really caught Chu Fei's attention was the "knight" on Albatross's back, who was clearly a person, an awakened person.

After Chu Fei slowly approached, the awakened person shouted: "Oh, this is Chu Fei, hahaha...

The king said that there might be mice coming, let us patrol the mountain.

Unexpectedly, he won the grand prize. "

big prize?Chu Fei narrowed his eyes and touched the weapon. (end of this chapter)
