Two hours later, the Iron Dragon in the sky passed through a thick cloud like a huge one, and in less than a minute, when the Iron Dragon left this cloud, Zhang Tie had already left the Iron Dragon, and appeared in this cloud layer tens of thousands of meters in the air unconsciously.
At the speed of the Iron Dragon, here, it has left the boundary of Longxi County, Zhongzhou.
Pingsha Valley may still be rainy at the moment, but here, it is a crisp autumn sunny weather, the sky is full of white clouds, from time to time there are airships flying under the clouds, and on the horizon in the distance, there is a faint outline of a prosperous city.
In several rooms on the Iron Dragon, there are secret passages that facilitate the knight to quickly enter and exit the Iron Dragon, which is convenient for escape and special tasks, these secret passages can only be opened from the inside, and after opening for a few seconds, they will automatically close, one of the secret passages is in Zhang Tie's retreat cultivation room, Zhang Tie came out of the secret passage, except for Bai Suxian, no one knows at all.
The surrounding white clouds are surrounded, and the visibility in the white clouds is less than 100 meters, and the people outside can't see what is in the white clouds at all.
I have to say that at this time, leaving the Iron Dragon, becoming alone, doing whatever he wants, Zhang Tie once again felt the state of mind and freedom of being free and unrestrained, it has been a long time, Zhang Tie has not had such a relaxed experience.
In the past few years, Zhang Tie has either been on the run or thinking about how to wash away his grievances or simply keep fighting and acting alone again, don't say it, this feeling is really good.
Zhang Tie waited in the white clouds for more than ten minutes, as the white clouds floated in the sky for a distance, and when the Iron Dragon had completely disappeared into the sky, Zhang Tie had changed into an ordinary middle-aged man wearing a blue robe, thick eyebrows and black face, and a thin hair.
After doing this, seeing that there were no knights and flying boats within dozens of kilometers around, Zhang Tie flew out of the clouds, and in broad daylight, turned into a small dot in the sky, and flew towards the north, while the height of his body from the ground was getting higher and higher.
In Zhang Tie's perception, the thunder falcon flying towards him seemed to be very excited when it felt Zhang Tie flying in his direction, and its flight speed actually increased by nearly 30% again, which startled Zhang Tie, and then there was an indescribable emotion.
This is the feeling of watching the puppy that I raised since I was a child leave me for several years, and when I see myself again when I grow up, I am desperate to wagging my tail and galloping towards me.
At this time, Zhang Tie's speed was not slow, just a few breaths of time, Zhang Tie's flight speed in the sky had already exceeded 900 kilometers per hour, and while the speed was increasing, in the blink of an eye, he entered the stratosphere more than 20 kilometers above the ground.
Entering the stratosphere, Zhang Tie's figure continues to rise, and his speed has exceeded 1,000 kilometers per hour.
The two chakras of the Infernal Peng King Sutra that he condensed are running low and powerful, dignified as a mountain, extremely calm, just like an efficient and surging engine has just begun to intervene in the working speed range, this running chakra not only completely cancels out the gravitational pull of the earth under his feet, but also makes Zhang Tie burst out at greater speed, and has an urge to try to fly higher and fly faster.
Savoring 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 an instinct that operated from the Infernal Pengwang Meridian Chakra that he had cultivated.
In this era, the Terran aircraft, airships and gliders and other aircraft flew in the troposphere within 20 kilometers above the ground, while the flying boats and knights could enter the stratosphere above 20 kilometers above the ground to 130 kilometers below the stratosphere.
And this instinct of the Infernal Peng King Sutra is a little strange, it is actually because Zhang Tie felt a little envious of the terrifying flight speed of the Thunder Falcon, and then Zhang Tie felt that the law of the Infernal Peng King Sutra that had been hidden in the Divine Palace was actually faintly restless, very strange.
It was driven by this curiosity and emperor-level exercise instinct, coupled with the fact that the time and place were quite right at the moment, a wave of pride rose in Zhang Tie's heart, and Zhang Tie wanted to see where the limit of his flight was.
Since advancing to the Earth Knight, Zhang Tie really hasn't had a chance to try this ability of his own.
Thinking so, Zhang Tie's body continued to rise, and the speed increased again, breaking through the limit of 1,100 kilometers per hour for the first time, and at this speed, Zhang Tie's ground clearance soon reached the top area of the stratosphere more than 130 kilometers above the ground.
At this height, the air is even thinner, but under the feet is a white sea of clouds, the whole person's feeling, just like standing on top of a high-rise building to look at a cotton field, the things on the ground below the cotton field, in the field of vision of ordinary people, except for some very large individuals, such as cities, mountains, lakes, and the long railroad occasionally peeking a little outline from under the cotton field, other things are almost imperceptible.
Of course, this is the case for ordinary people, but for Zhang Tie, who has the eyes of lotus blossoms, the higher he flies, the better he can get a better field of vision, even at this altitude, as long as he is willing and concentrated, he can clearly see every grass and tree on the ground.
Thinking of the thing called reconnaissance satellites before the cataclysm, Zhang Tie suddenly had a funny idea, compared to those metal instruments, it seems that he is a veritable "artificial satellite".
Zhang Tie didn't know why other Earth Knights rarely mentioned the atmospheric space above the stratosphere, but at least in his opinion, it didn't seem to be much difficulty for him to break through the stratosphere at all, both his feelings and the chakras that were still functioning normally gave him a lot of confidence.
Almost without any obstacles at all, Zhang Tie suddenly flew high into an atmospheric space more than 130 kilometers above the ground, the first feeling of entering this space was cold, the second feeling was that the convective movement of the air flow that had appeared in the troposphere reappeared, and the third feeling was that after his flight speed exceeded 1200 kilometers per hour, an invisible barrier appeared in front of him for the first time Sound impairment, a word appeared in Zhang Tie's mind
