Watching Chu Fei fly to the sky with a "panic choice", Chen Qiang sneered, "Chu Fei, you can't escape!"

Then he chased and greeted new supporters to pursue.

Under the power of the magic scroll, the speed of Chen Qiang and three other magicians also soared rapidly, quickly breaking through the speed of sound, and continued to soar, rushing to high altitude.

However, as the speed increases, the power of the magic scroll is rapidly consumed.

During ultra-high speed flight, strong air shock waves have also become a huge obstacle.

Chu Fei was not relaxed either. It was very difficult to fly to high altitude, but Chu Fei also had his own plans.

During ultra-high speed flight, Chu Fei needs to make more calculations, and the calculation volume increases rapidly; the shape of the Wind Wings is constantly adjusted.

From a swept wing state, it becomes a forward swept wing, from a wide wing to a narrow wing, from a double wing to a six wing, and then it becomes a four wing.

As the speed increases, the surface area of ​​Wind Wings continues to decrease. A layer of wind shield also appeared on Chu Fei's body, and the wind shield is streamlined, reducing air resistance.

During the rapid flight, Chu Fei constantly adjusted the Wind Wings and continuously calculated the data one by one; finally even modified the structure and underlying data of Wind Wings according to the actual situation.

Ultra-high-speed flight and low-speed flight involve very different theories.

Finally, Chu Fei's Wind Wings adopted the most classic canard wing design.

The two main wind wings were like two scimitars pressing against the back, forming a shuttle shape; on Chu Fei's ankles, there were two small wind wings, like tail rudders, and they also played the role of candles and tail rudders.

However, after more than ten seconds, Chu Fei's shape had completely changed. He was like a humanoid fighter, sprinting in the sky.

The flight altitude quickly exceeded five kilometers and continued to break through ten kilometers. Chen Qiang and three other magicians followed closely behind, and the distance between the two sides was gradually getting closer.

A sneer appeared on Chen Qiang's face.

Seeing this, Chu Fei did not change his direction and continued to break through upwards.

As the height increases, the atmosphere changes rapidly. The high air pressure is low, the temperature is low, but the wind speed is not low.

Also, the decrease in air density at high altitudes also leads to a decrease in sound speed.

The decrease in air density leads to a decrease in resistance.

These changes directly affect the effect of the spell.

Countless information flashed through Chu Fei's mind, data were calculated one by one, and his flight methods and spells were constantly adjusted.

As the air density decreases, Chu Fei's wind wing area begins to increase. After adjustment, Chu Fei's speed continues to increase.

The three figures chasing behind finally showed negative changes, and Chu Fei's expected changes occurred - the speed began to decrease!

Although magic is somewhat "not scientific", it is all appearances.

In fact, no existence can come out of thin air and must be based on it.

Magic may involve some faith, dark energy and dark matter, but since it is something from the real world, we have to talk about science.

The science here refers to the broad meaning and respects the laws of nature.

For example, a person will die if he is killed ~

When the three figures rushed to a high altitude, to be precise, they rushed over 10 kilometers and their speed dropped sharply.

The atmosphere has a relatively obvious layering around 10 kilometers.

The troposphere is below 10 kilometers, and the stratosphere is above 10 kilometers. Although this boundary is not clear, the atmospheric environment does have obvious changes.

Chu Fei made timely adjustments to adapt to this change - this is also due to Chu Fei's usual learning and accumulation.

However, the three magicians chasing did not make adjustments in time.

Chu Fei turned his head and took a look, slowing down a little - Crazy diving, very tired.

When the three magicians saw that Chu Fei's speed had also decreased, they immediately felt that Chu Fei was just like that. There were three of them, and the magic scroll.

The three of them inspire the magic scroll again and continue to pursue.

When both sides broke through 12 kilometers one after another, the cold high-altitude atmosphere and the atmosphere were obviously thin, the speed of the four people continued to decrease.

But the pursuit was not over, and Chu Fei was still flying high, but the distance between the two sides gradually widened!

As the altitude increased, Chu Fei's flight speed exceeded the speed of three magicians.

Chen Qiang's face turned pale. He didn't expect that the carefully prepared ambush would be the result. Damn, can you fly a little higher?

Chu Fei... continued to fly. Although his speed continued to decrease, Chu Fei still barely flew to an altitude of 15 kilometers!

At Chu Fei's feet, at an altitude of about 14 kilometers, the three magicians had stopped rising, but they were still hiding Chu Fei.

Chen Qiang inspired a magic scroll again and said hatefully, "I don't believe you can fly without falling."

Before he finished speaking, he sneezed hard and shivered a few times. There was no way, this height was a little cold.

Chu Fei floated above the three of them, with the corners of his mouth slightly raised, and there was a faint coldness of a blade.

Then Chu Fei looked at the Wisdom Tree intently. Chu Fei had used a lot of dewdrops from the Wisdom Tree, but he had made up for it at this time.

Since entering the semi-finals, Chu Fei's dewdrops of wisdom tree have been continuously dewdrops, which is quite inexhaustible.

Without hesitation, using five drops of dewdrops, there was a flash of light in Chu Fei's eyes.

"The hunting time has come!"

Chu Fei's head and feet flashed through his mind.

"Boom..." The wind wings behind it expanded to a length of three meters, with a wingspan of as much as 6 meters. With the help of dive and the gravity of the earth, Chu Fei's flying speed quickly exceeded 300 meters/s.

Below, Chen Qiang saw Chu Fei diving, sneered, and took out the magic scroll from his arms again.

The magic scroll was activated, and the magic wings behind Chen Qiang surged, and his figure rose rapidly, sprinting towards Chu Fei - everyone left a hand.

Although I, Chen Qiang, are not familiar with the situation at high altitude, I know it!

Chen Qiang had mockery on his face.

The two approached quickly and reached a hundred meters in the blink of an eye.

The two of them sprinted against each other, and a hundred meters was just a blink of an eye.

However, at this moment, Chu Fei took action.

Prediction, small immobilization technique!

At this time, Chu Fei's potential was approaching 11.0, but he also swallowed five drops of dewdrops of wisdom tree, and his mind was filled with unimaginable knowledge.

After the release of this small immobilization technique, it instantly solidified a range of more than ten meters in an radius.

Just as the small immobilization technique was completed, Chen Qiang hit him head-on.

"Boom..." Chen Qiang felt dizzy, his eyes turned black, and his magic was out of control and collapsed.

What a Chen Qiang, who did not hesitate at such a critical moment, and with the last little magical power, he barely rolled over his figure.

A wind blade flew over Chen Qiang's shoulder, bringing up a little blood.

If Chen Qiang had no changes just now, the wind blade could cut open his neck. But a little change was just a stroke across his shoulder and it was only a minor injury.

Chu Fei looked at Chen Qiang in surprise, you should be called Xiaoqiang.

However, Chu Fei was too fast now, and he passed by Chen Qiang and had no time to launch a second attack.

Missing Chen Qiang, Chu Fei headed straight to the next target.

Compared to Chen Qiang's agility, the other two are a little stupid. Not only is the air thinner at this high altitude, but it is a little cold. Chu Fei rushed over, and these two guys were still rubbing their hands.

Chu Fei went straight to the closest one to him, his diving speed had exceeded 420 meters/s, and his figure was like a flash of lightning.

A wind blade flew past, and the sound of silk cracking appeared in the air. Unfortunately, Chu Fei could no longer hear it. At this time, Chu Fei's speed exceeded the speed of sound and rushed towards the next target.

The second target is thousands of meters away from Chu Fei, and it takes Chu Fei 2.5 seconds to fly.

Behind Chu Fei, a figure was torn apart by the wind blade. Chu Fei's wind blade penetrated the other party's chest and blood sprinkled in the sky.

Another magician who rubbed his hands finally reacted and screamed. After hesitating for a moment, he saw Chu Fei rushing towards him like lightning, and immediately activated the magic scroll and rushed towards Chu Fei.

The two hedge.

Chu Fei's eyes looked like an eagle.

The two of them quickly approached, with a distance of less than 100 meters in the blink of an eye.

At this moment, the other person's figure was slightly tilted a little. He actually dodged Chu Fei's attack direction. After missing Chu Fei's figure, he did not stop and continued to accelerate forward, accelerate... and run away!

Moreover, this man actually learned Chu Fei's dive method and used dive to increase his speed.

Chu Fei:...

I looked up at the sky again, but saw that Chen Qiang also used dive to accelerate and ran away.

With the blessing of magic, the two guys could no longer see their backs in a blink of an eye.
Chapter completed!
