Volume 38 Chapter 39

The invisible sound barrier in the air is like an extremely elastic film blocking Zhang Tie's face.

This layer of film is not terrible, Zhang Tie feels that he is fully capable of easily passing through it and breaking it, but for some reason, Zhang Tie has tried many times, but cannot break through this layer of sound barrier.

The chakras of the "Wu Jian Peng Wang Jing" are still running steadily, providing Zhang Tie with endless power. Zhang Tie feels that this speed is still not his limit. His ability has not been utilized yet, but what makes Zhang Tie want to vomit blood is that he obviously feels that he can easily break through this sound barrier, but in fact, no matter how hard he tries and struggles, his speed, They are always hovering around 1200 kilometers per hour. This speed may be scary to ordinary knights, but to Zhang Tie, it is not satisfied.

This kind of feeling is like you are clearly driving a Sendra T9, but you can only run slowly on the highway at a speed of 40 yards. The engine of the Scion t9 and the performance of all aspects of this car can fully support you to run more than 200 yards. You are also a racer yourself, but always, no matter how you step on the accelerator, you can only run within 40 yards. Toss on speed.

Where is the problem?

If this happens to a sports car, it is estimated that you did not put the car's gearbox into a higher gear.

But for Zhang Tie, who practiced the "Wu Jian Peng Wang Jing", in such a situation, he obviously had the powerful flying ability bestowed by the "Wu Jian Peng Wang Jing", but he couldn't burst out. Obviously, I felt that I could easily break through the sound barrier but finally stopped in front of the sound barrier. Then, there is only one problem in the complete "Wu Jian Peng Wang Jing". There is definitely a corresponding flying secret method that goes with it, which can release the powerful flying ability and talent of the "Wu Jian Peng Wang Jing". That's why it's so hard to feel.

Above the stratosphere, Zhang Tie remembers it should be the middle layer in the atmosphere.

While Zhang Tie was trying to break through the sound barrier, he also felt two obvious characteristics of the middle layer. The first characteristic of the middle layer is coldness, and the higher the middle layer is, the colder it is. In the middle of the middle layer, the temperature can reach below minus 50 degrees. The so-called biting wind should be like this. The second characteristic of the middle layer is the very obvious air convection movement.

The temperature below the middle layer is high, and the temperature above is low. This situation is very similar to the situation in the troposphere. Therefore, the middle layer also has the convective movement of the airflow in the troposphere, and it is more intense.

Zhang Tie didn't care much about the cold temperature, whether it was his body protection or his own cold resistance. They are all transcendent, and the super-strong airflow in the middle layer is for Zhang Tie. Just like the undercurrent in the seabed,

It can be used as a booster for his flight, allowing him to achieve greater speed with less effort.

In the past, he relied on the keen instinct cultivated by his body to feel the airflow movement, but now. In the case of having the Eye of the Lotus Blossom, because the airflow movement in the middle layer itself is generated by the temperature difference. Zhang Tie could even see the direction of movement of the various airflows in the middle layer.

Under the Eye of Lianhua, the cyclonic air column generated by the invisible airflow in the middle layer is like super large color-changing mushrooms planted in the middle layer one by one. Thousands of kilometers, very spectacular.

Zhang Tie has tried many times. Relying on the effect of airflow, he can indeed save energy when flying and sometimes be more flexible, but no matter how strong the airflow is, no matter how well he uses it, he still can't break through the airflow. layer sound barrier.

When rising to an altitude of more than 400 kilometers above the top of the middle layer, Zhang Tie saw for the first time on the distant horizon the outline of a faint arc of the land under his feet. While seeing this outline, Zhang Tie Iron also feels a kind of pressure, which is very similar to the sound barrier, that is, you obviously feel that you have the ability to fly higher, but there seems to be a transparent ceiling above your head, preventing you from continuing to fly upwards.

Zhang Tie knew that if he could not master the flying secrets of "The Infinite Peng Wang Jing", then the speed of about 1200 kilometers per hour and the top area of ​​the middle layer of the atmosphere above 400 kilometers above the ground should be what he can achieve now The limit speed and altitude of the flight.

Zhang Tie flew in the middle layer for eight hours, and had already flown out of the range of Zhongzhou and Longxi County.

After flying more than 9,000 kilometers, Zhang Tie didn't feel tired, and felt a little depressed. The thunder falcon he felt was flying towards him like lightning, with a speed of more than two Mach, almost reaching 3,000 kilometers per hour. Tired, I am a majestic knight of the earth, and I am practicing the "Infernal Peng Wang Jing". In terms of flying ability, I am not as good as a bird?

But depression is depression, Zhang Tie also knows that this kind of thing can't be rushed, unless he can get the complete "Infernal Peng Wang Jing", otherwise, he can only slowly find a way to improve his flying ability. However, if there is a full version of "The Infinite Peng Wang Jing", once this kind of emperor-level cheat book appears, I don't know how much turmoil will be caused among the two races of humans and demons. People above the rank are afraid to move. I am an earth knight. In this kind of competition, I guess I don't even have the qualifications to play.

During these several hours of flight, Zhang Tie also encountered three waves of knights and two flying boats in the sky.

The two flying boats were flying in the stratosphere, and Zhang Tie was not found at all. The two sides passed by each other. The remaining two waves of knights, one wave consisted of three people, two earth knights and one black iron knight, were also in the stratosphere. During the flight, this wave of people found Zhang Tie flying above them, but there was no communication. The two sides left separately. The second wave of knights were two earth knights. When they saw Zhang Tie, the two earth The knights didn't know why, but they seemed to be very curious about Zhang Tie's ability to fly in the middle layer. They chased Zhang Tiefei for a while in the stratosphere, as if they wanted to see what Zhang Tie looked like, but Zhang Tie didn't have any interest in communicating with them, so he flew directly. gone.

The flying speed of these two waves of knights in the sky did not exceed 900 kilometers per hour.

What really shocked Zhang Tie was the third wave of knights he met. In fact, there was only one person in the third wave of knights. It was a phantom knight, who was flying in the middle layer in the form of a hydra. Phantom Knight...(to be continued)
