Two hours later, the Tielong in the sky passed through a thick cloud like a giant cotton candy. In less than a minute, Zhang Tie had already left when the Tielong left the cloud. After the Iron Dragon, God appeared unconsciously in this tens of thousands of meters high in the clouds.

At the speed of the Iron Dragon, this place has already left the boundary of Longxi County in Zhongzhou.

Pingsha Valley may still be rainy and rainy at the moment, but here is a clear and sunny autumn weather, white clouds in the sky, from time to time airships fly by under the clouds, and on the horizon in the distance, there is a vaguely prosperous city. Outline.

In several rooms on the Iron Dragon, there are secret passages that are convenient for knights to quickly enter and exit the Iron Dragon, which is convenient for escape and special missions. These secret passages can only be opened from the inside, and then automatically closed after a few seconds. A secret path was in Zhang Tie's closed training room. Zhang Tie came out of the secret path. No one knew except Bai Suxian.

Surrounded by white clouds, the visibility in the white clouds is less than 100 meters, and people outside can't see what is in the white clouds. Being in the white clouds, volleying in the sky, fluttering and fluttering, it really feels like a fairy.

I have to say that at this time, leaving the Tielong and becoming alone, doing whatever he wants, Zhang Tie once again felt the state of freedom and freedom. It has been a long time, and Zhang Tie has not been so relaxed. The experience.

In the past few years, Zhang Tie has either been fleeing or thinking about how to clean up his grievances for himself or simply fighting non-stop, acting alone again, let alone, this feeling is really good.

Zhang Tie waited in the white clouds for more than ten minutes. As the white clouds floated a certain distance in the sky, when the Tielong had completely disappeared from the horizon, Zhang Tie had changed into a blue gown with thick eyebrows and a black face. With the image of an ordinary middle-aged man with slab-inch hair, the aura of strength exuded from the whole person has also become chaotic and unpredictable, making it difficult to distinguish between reality and reality.

After doing this, seeing that there were no knights and flying boats within tens of kilometers around, Zhang Tie flew out of the clouds and turned into a small dot in the sky in broad daylight, flying towards the north while his body was off the ground. The height is getting higher and higher.

In Zhang Tie’s perception, the thunder falcon flying towards him seemed very excited when he felt Zhang Tie flying towards him. Its flying speed actually increased by nearly 3% again. Ten, Zhang Tie was shocked, and then there was a burst of unspeakable touch.

This is a feeling of watching the puppy that I have raised since I was a few years away from myself, and when I see myself again when I grow up, desperately wagging its tail and rushing towards me.

At this time, Zhang Tie’s speed was not slow, just a few short breaths, Zhang Tie’s flying speed in the sky had already exceeded 900 kilometers per hour, and while the speed was increasing, in the blink of an eye, As soon as he entered the stratosphere 20 kilometers above the ground, a knight flew in the stratosphere at a high speed. It was almost difficult for people on the ground to find the knight.

Entering the stratosphere, Zhang Tie's figure is still rising, and his speed has exceeded 1,000 kilometers per hour.

The two chakras of the self-condensed Wujianpengwangjing are running in a deep and powerful manner, dignified as a mountain, and extremely calm, just like an efficient and surging engine has just begun to intervene in the working speed range. This running chakra is not only completely It counteracted the gravitational force of the ground under his feet and made Zhang Tie explode to a greater speed. He had the urge to try to fly higher and faster.

Savour this impulse, Zhang Tie was surprised to find that one third of this impulse came from Zhang Tie’s curiosity, and the remaining two-thirds actually came from the pulse of the "Wu Jian Peng Wang Jing" he had cultivated. An instinct to turn the wheel.

In this era, Terran aircraft, airships and gliders, all fly in the troposphere within 20 kilometers above the ground, while flying boats and knights can enter the stratosphere between 20 kilometers and 130 kilometers above the ground. During mid-flying, over this altitude, he entered another atmosphere. Zhang Tie had never experienced what was happening in the other atmosphere, nor had he heard other earth knights talk about it, so he was a little curious.

The instinct of "The Infinite Peng Wang Jing" is a bit strange, because Zhang Tie felt that the thunder falcon's horrible flying speed was a little envious, and then Zhang Tie felt that the Infinite Peng Wang who had been hidden in the palace The Buddhist scriptures actually faintly agitated, very strange.

Driven by this curiosity and the instinct of a great emperor-level technique, plus the time and place are still appropriate at the moment, a sense of pride arises in Zhang Tie’s heart. Zhang Tie wants to see how his limit of flight is. where.

Since the advancement of the Earth Knights, Zhang Tie really had no chance to try his ability.

Thinking about this, Zhang Tie’s body continued to elevate, and his speed accelerated again, breaking through to the limit of 1,100 kilometers per hour for the first time. At this speed, Zhang Tie’s height from the ground soon reached an advection above 130 kilometers above the ground. The top area of ​​the layer.

At this height, the air is even thinner, and there is a vast sea of ​​clouds under your feet. The whole person feels like standing on a high-rise building and looking at a cotton field. The things on the ground under the cotton field are like ordinary people. In the field of vision, except for some very huge individuals, such as cities, mountains, lakes, and long railroads that occasionally reveal a little outline from under the cotton fields, other things are almost imperceptible.

Of course, this is true for ordinary people, but for Zhang Tie, who has the eye of lotus, the higher he flies, the better his vision. Even at this height, as long as he wants to and concentrates, the ground He could clearly see all the vegetation on it.

Thinking of the things called reconnaissance satellites before the cataclysm, Zhang Tie suddenly came up with a funny idea. Compared with those metal instruments, he seemed to be a truly "artificial satellite".

Zhang Tie didn’t know why other land knights rarely mentioned the atmospheric space above the stratosphere, but at least in his opinion, it seemed that he wanted to break through the stratosphere without much difficulty, no matter how he felt it was still working normally. The chakras gave him a lot of confidence.

There were almost no obstacles. Zhang Tie flew high into an atmospheric space more than 130 kilometers above the ground. The first feeling of entering this space was cold, and the second feeling was the convection of the air current that once appeared in the troposphere. Movement appeared again, the third feeling, after his flying speed exceeded 1,200 kilometers per hour, an invisible barrier appeared in front of him for the first time...

The sound barrier, a word appeared in Zhang Tie's mind.
